Page 11

2.2.2 Safety Information for the Operator

 Using this instruction manual, which must be provided with the bed, ensure

that every user is instructed in the safe operation of this bed before using it
for the first time.

 Draw every user’s attention to the possible hazards that can arise if the bed

is improperly used. This applies in particular to the use of electrical drives
and safety sides.

 In order to ensure permanently safe operation of this medical product with

no risk to occupants, users and third parties, observe your obligations in
accordance with MPBetreibV (Medical Devices Operator Ordinance).

 If the bed is in long-term use, test the functions and check for visual

damages (see Chapter 6.2) after a reasonable period of time
(recommendation: annually).

 Only permit persons who have been properly instructed to use this bed.
 Make sure that substitute staff is also sufficiently well instructed in the safe

operation of the bed.

 When other additional equipment (e.g. compressors for positioning systems,

etc.) is attached, ensure that all equipment is safely mounted and
functioning. Pay special attention to:

o Safe hook-up of all loose connector cables, tubing, etc.
o No multiple socket outlets are located under the bed (fire hazard in the

presence of penetrating fluids).

o Chapter 2.3.1of this instruction manual

In the case of ambiguity, consult the manufacturer of the additional
equipment or the Stiegelmeyer company.

 Check that your staff is complying with the safety information.

Instruction Manual for Care Bed Libra

Page 12 -

2.2.3 Safety Information for the User

 Route the cable for the transformer unit in such a way that it

cannot be pulled, driven over or damaged by moving parts
when the bed is operated.

 At regular intervals, carry out a visual inspection of the

transformer unit cable to check for mechanical damage
(scuffing, exposed wires, kinks, pressure points, etc.). Such a
check should be performed:

o Whenever the transformer unit cable has been subjected to

any mechanical load, e.g. has been driven over by the bed
itself or by an equipment trolley, has been bent, stretched or
violently pulled due to the bed rolling away while still
plugged into the wall socket.

o Whenever the bed has been moved or relocated before

plugging it back into the transformer unit.

o Regularly by the user when the bed is in constant operation.

 If any damage or malfunction is suspected

o unplug the transformer unit immediately from the power

supply.

o indicate clearly that the bed is “Out of Order”
o and take it out of service and
o report it immediately to the operator responsible.

 Check the strain relief of the mains cable regularly to ensure that

the screws are tight and secure.

 When using external electrical components such as patient lifts,

reading lamps, or compressors for positioning systems, ensure
that all equipment mains cables will not become entangled or
damaged by the moving parts of the bed. This will prevent
potential hazards due to electric shocks, fire, etc.

 Multiple sockets that are placed loosely on the ground should

not be used for connecting external electrical components.
Otherwise electrical risks might occur due to damaged mains
cables or penetrating liquid.

Before moving the bed, it is important to always unplug it from the
power supply. Store the transformer unit cable in the cable holder
provided to ensure that it will not fall off or trail on the floor.
(See here Chapter 4.4.1).

 Ensure that the operator instructs you in the safe operation of

this bed.

Instruction Manual for Care Bed Libra

Page 13

 Each time before using the bed, check that it is in perfect

working order to prevent unnecessary hazards for the patient
and delays to work procedures (see Chapter 3.1).

 Make sure that the mattress base has travelled to its lowest

position before leaving the occupant unattended. In this way,
you greatly reduce the risk of the occupant injuring
himself/herself as a result of falling when getting in or out of
bed.

 Place the handset out of reach (e.g. at the foot end) to protect

the occupant against accidental motor-driven adjustments or
lock the adjustment options of the handset if:

o The occupant is unable to operate the bed safely or free

himself/herself from potentially dangerous positions.

o The occupant could be at risk due to inadvertent adjustment

of the electric motors.

o The safety sides are raised (risk of limbs being crushed or

trapped when adjusting the backrest or thigh rest).

o Children are left unsupervised in the room with the bed.

 The adjustments may then only be carried out by, or in the

presence of, an instructed person.

 Ensure that no obstacles such as night tables, window sills,

sloping ceilings, floor cable ducts or chairs could impede
adjustments to the bed, to prevent damage to load-bearing
parts of the bed and to the obstacles.

 When not in use, always stow the handset in such a way that it

can not fall onto the floor (hang it on the hook). Make sure that
the cable will not be damaged by moving parts of the bed.

2.3.6 Structural Design

Mattress base

The mattress base is divided into a backrest, a fixed seat section, a thigh rest
and a lower leg rest. The rests are adjustable. The mattress base can be raised
and lowered horizontally or set to the reverse Trendelenburg position with the
foot end lowered (optional Trendelenburg position also available).

Chassis

The chassis is constructed from welded steel tubing with an optimised scissor
lift design and is equipped with four castors which can be locked in by axle at
the foot and head ends.

Safety sides
To protect the occupant from falling out, the bed has full-length safety sides
(2), or, optionally,

 a combination safety side (Mobivit) (6),
 a swivelling safety side (A),
 a split safety side MobiFlex (D).

The safety sides can be raised, one after the other, from the lowered position
to protect the occupant and then lowered again.

Electric Drive System

The electrical drive system for this bed is single fault-safe and flame-retardant
(V0) and consists of:

 an 'external' power supply. The transformer unit consists of: Power

converter and low-voltage connecting cable. The power converter
generates a safe, low voltage current which is not dangerous for
occupant or operator. The transformer unit provides protective low­voltage power to the control for all drives (motors) through a connecting
cable.

 the central control device. All drive motors and the handset, which work

on this safe low voltage are plugged into the central control unit.

 the electric motors for the backrest and the thigh rest.
 two electric motors for the mattress base height adjustment.
 a handset with a flexible hook.

service for the first time, since the bed has been tested by the
manufacturer for electrical safety and functionality and left our factory in
perfect condition.

Before putting the bed into service for the first time:

 Remove all transport securing devices and packaging film.
 Clean and disinfect the bed.

Before putting the bed into service each time:

The user must check that:

- The bed has been cleaned and disinfected.

- The castors are braked.

- The power supply is compatible with the bed (100 - 240 volt AC, 50/60

Hertz).

- The transformer unit is connected and the power cable is routed in such

a way that it cannot be damaged through bed adjustments /being
driven over. Hang any cable which is not being used on the cable
holder (see Chapter 4.4.1)

- The transformer unit, drive cables and handset cable cannot be

damaged by moving parts of the bed.

- No obstacles such as bedside lockers, floor cable ducts or chairs will

inhibit adjustments.

- All adjustment facilities work properly and have been checked (see

Chapter 3.1).

The care bed may be put into operation only after carrying out these
checks!

3.2 LOCATION REQUIREMENTS

 There must be sufficient room available to accommodate the bed's entire

range of adjustments. Furniture, window sills, etc. must not impede
adjustments.

 Before using the bed on parquet flooring, check whether the castors could

leave marks on the parquet varnish. The bed can be used on tiles, carpet,
linoleum or laminate flooring without causing any damage.

 A properly installed 230 Volt mains socket must be available close to the

bed (preferable).

 For transformer unit:

o Hang any cable which is not being used on the cable holder

under the head end.

o Only insert transformer into socket vertically with  the cable

end downwards.

o Be careful when moving the bed away: Ensure that the cable

is long enough; unplug transformer unit first.

o Take care when adjusting the height: Maintain a sufficient

distance at the side between the bed and the
transformer unit to avoid damage from occurring. (If necessary, use a
wall spacer)

 If any other equipment is attached to the bed, (e.g. compressors for

positioning systems, etc.), ensure that this is securely fastened and that all
additional devices are functioning properly. Pay special attention here to
the safe routing of all loose connector cables, tubing, etc. If you have any
queries or concerns, consult the manufacturer of the additional equipment
or Stiegelmeyer care furniture.

Observe the following points when positioning the bed in order to

minimise, as much as possible, the risk of fire due to external

influences. Instruct users on these points!

 Preferably use only flame-retardant mattresses and bedding.
 Avoid smoking in bed since the mattress and bedding used may not be

resistant to smoking materials or smoking accessories.

 Only use additional equipment which is in perfect working order (e.g.

electric blankets) and other electrical devices (e.g. lamps, radios)!

 Ensure that this equipment is used only for the purpose intended and that

instruments are not left unintentionally on or under the bedding (danger of
overheating)!

 To prevent risk of fire, do not use any plug connectors from extension

cables or multiple socket bars under the bed.

4 Operation

4.1 MOVING AND BRAKING THE BED

The bed is equipped with four lockable castors. The bed is delivered with the
standard paired braking (at head and foot end) (10). If desired, the customer
can order a bed equipped with central braking at the foot end. The bed can
also be moved in the room when occupied.

 The bed is not suitable for being moved often and over long

distances outside the room in corridors, across thresholds or on
very uneven floors.

 Bring the bed to the lowest mattress base position when moving

the bed greater distances outside of the room.

 Each time before moving the bed, ensure that:

o The mains cable cannot be stretched, driven over or

damaged in any other way.

o When moving the bed the mains cable is always stowed in

the designated mains cable holder and does not trail on the
floor (see Chapter 4.4.1)

o Cables, tubes or conductors of mounted additional

equipment that are possibly attached are sufficiently
secured and cannot be damaged.

Otherwise these could be damaged due to the mains cable
being torn off, driven over or crushed. These damages may
lead to electrical risks and malfunctions.

 Ensure that the bed is always sufficiently braked when an

occupant is left unattended.

Depending on the location (e.g. by a wall or in a niche), it may be
sufficient to brake only two of the castors. If the bed is standing on
a sloping floor (e.g. on a ramp), then all four castors must be
braked.
A safe and secure bed position must always be guaranteed!

Instruction Manual for Care Bed Libra

Page 23

4.1.1 Individual axle braking (Standard)

Operate the castors, one set after the other, on either side at the head or foot
end of the bed. This allows the castor sets at each end of the bed to be
operated with one lever.

Travel: Raise the foot lever (at the foot
and head end) with your foot.

Braking: Press down on the foot lever
(foot and head end) with your foot.

4.2.2 Manual emergency release of backrest

In the event of power supply outages or electrical drive system failures, the
raised backrest  can be lowered by hand.
Optionally also by using the 9-Volt batteries (See Chapter 4.3.6).

Please note: Manual emergency release of the backrest requires

two people!

Disregard for this safety information and instructions for use may cause
the backrest to fall uncontrollably, which could lead to serious injuries
for both user and occupant!

 Emergency lowering may only be carried out in the case of extreme

emergencies and by users who have a complete command of the
procedure described below.

 We strongly advise you to practice emergency lowering of the

backrest under normal conditions. That way, in the case of
emergency you will be able to react quickly and accurately.

Before lowering, the load on the
backrest  must be removed.

 To do this, the first person raises

the backrest  slightly by  the
frame and holds it in this
position.

 The second person now

removes the bolts . To do this,
open the bent rail  and pull
the bolts out along with the rail
from the lifting bar of the
backrest motor.

 The motor is now separated from the

backrest.

 Place the motor on the bed frame by

hand.

 After the second person has left the

danger zone, the first person (with the
help of the second person) lowers the
backrest carefully.

Hold the backrest firmly when lowering, otherwise it could fall
uncontrollably!

 Now the motor on the lifting bar is no longer connected to the motor

connector mount.

 The lifting bar remains in the position it was in when emergency lowering

was carried out.

4.2.3 Emergency release of backrest using Quick Release (optional)

If a power outage or
outage in the
electrical drive system
has occurred, it is
possible to manually
lower a raised
backrest by one
person without
removing the motor
through a Quick
Release device.

There is a red
operating lever on the
head end on the bed
frame .

 Risk of crushing! When lowering the rests, ensure that the patient’s

limbs are not underneath the backrest. Otherwise, the weight of
the rests could cause limbs to be trapped or crushed.

 The backrest can drop very quickly in the case of heavy occupant

once the operating lever has been activated!

 Always grip the backrest by its frame with one hand  so as to

“control” the adjustment.

Proceed as follows:

1. Grasp the frame of the backrest  with one hand.

2. With the other hand, push the red operating lever  upwards and guide

the backrest down to the desired position.

 Hold the operating lever down until the backrest is completely

lowered.
The backrest can also be held in position by letting go of
the red operating lever.

4.3 ELECTRICAL ADJUSTMENT OPTIONS

4.3.1 Special Safety Information on the Electrical Drive System

 When making any adjustments, ensure that no limbs from the

patient, user or other persons, especially playing children, are
under the rests or the bed frame. Otherwise, this could lead to
trapped or injured limbs.

 Lock the operating functions for the occupant on the handset if

- The occupant is unable to operate the bed safely,

- The occupant is unable to free himself/herself from

potentially dangerous situations,

- The occupant is liable to an increased risk of entrapment

during backrest and thigh rest adjustments when the safety
sides are raised

- The occupant could be at risk from inadvertent adjustment

of the electric actuators,

- Children are left unsupervised in the room with the bed.

 Upon delivery of the bed, a locking key for the handset is

supplied along with this instruction manual. The locking key is not
intended for use by the occupant. The locking key should remain
with the user for safekeeping.

 Adjust the mattress base height whenever necessary, but at

least once a day, to the uppermost or lowest height. This
automatically equalises the two independent adjustment motors
and results in a level horizontal mattress base.

 When using accessories on electrically adjustable beds, the

following applies: Make sure that the arrangement of
accessories does not produce any crush or shearing zones for
the patient when the backrest and thigh rest are adjusted. If
that cannot be guaranteed, the user must safely prevent the
backrest and thigh rest from being adjusted with the handset.

 Make sure that the mains cable and the cable of the handset

cannot be trapped or otherwise damaged.

 Before moving the bed, always make sure that you have

unplugged it from the transformer unit supply. The transformer
unit may not fall to the ground or touch the floor ( 4.4.1). Not
observing these restrictions may cause the transformer unit to
become permanently damaged.

 Each time before moving the bed, ensure that the mains cable

will not be stretched, driven over or damaged in any other way.
When moving the bed, the mains cable must be stowed in the
designated mains cable holder ( 4.4.1).

 In order to avoid damages, ensure that no obstacles such as

furniture or sloped ceilings could impede adjustments to the bed.
This is to avoid damage.

Instruction Manual for Care Bed Libra

Page 29

 Patient lifts or other devices may be put under the bed. Ensure

when the mattress base is at the lowest height that the drive
components of the bed are not damaged – if in doubt raise the
mattress base height by about 10 cm before using the patient lift.

 Ensure that the 24 volt power supply cable and handset cable

cannot be driven over or otherwise crushed when the bed is
moved.

 In the case of malfunctions, an electronic overload switch

deactivates the drives in order to protect the control unit and
motor. Once the malfunction has been remedied, adjustments
are once again possible via the handset.

 Electrical adjustments are only possible when the bed is properly

connected to the mains supply

 If the load is too high, an electronic overload switch is activated

and the control unit is automatically switched off. When the
overload is removed, the drive unit system can be reactivated by
pressing the appropriate button on the handset.

 Continuous operation must not exceed two minutes! After this

time, a rest period of at least 18 minutes must be observed.
(Alternatively: one minute continuous operation followed by a
nine minute rest period, etc.)

 For safety reasons, when the maximum operation time is purposely

disregarded, a thermal safety device will permanently cut off the
power supply to prevent the drive unit system from overheating
due to continuous “playing”.

 The adjustment range for all functions is electrically / mechanically

limited to the permitted ranges.

 As with every electrical device, even if all specified limit values are

observed during operation, interference from and to other closely
situated electrical equipment cannot be completely eliminated

(e.g. “crackling” in a radio). In such cases, increase the distance

from the device. Turn off devices that have disturbance.

4.4.4 Patient lifting pole *

There is a round sleeve (A) with a notch (C) on the upper side at the inner
head end (E) of both corners of the mattress base frame. These are sleeves for
patient lifting poles. The patient lifting pole should be attached to the side of
the bed on which the occupant gets in and out. This will provide assistance
for the occupant when getting in and out of bed.

The maximum loading capacity at the front end of the patient
lifting pole is 75 kg.

 The patient lifting pole may not be swivelled beyond the area

of the mattress base and then pressure put on it. Otherwise the
bed may tilt. It is essential that you pay attention to this when
mobilising the occupant or bringing him/her to bed.

 The patient lifting pole is not suited for rehabilitation exercises

 Pay attention to door clearances when moving beds with

inserted patient lifting poles.

Inserting

Insert the long, straight end of the patient
lifting pole (D) into one of the two sleeves. The
metal pin (B) on the patient lifting pole must

standard bed comes with full-length safety sides (2) on both sides of the bed.
The bed can be fitted with the following variants of safety sides as an option.

 both bed sides with split safety sides (6)
 one bed side with full-length safety side (2) and the other side with split

safety side (6)

 both bed sides with split safety sides MobiFlex (D)
 both bed sides with swivelling safety sides (A)

The safety sides can be raised from the lowered position next to the mattress
base to protect the occupant.

Depending on the type of mattress base, there are two versions of safety

4.5.2 Special Safety Information for Safety Sides

Safety sides protect the occupant from unintentionally falling out of the care
bed. They are not intended as a device to prevent the occupant from
intentionally leaving the bed.

If not used properly, there is a considerable danger of, for example,
strangulation for the occupant! Please, therefore, bear in mind the following
instructions.

 Only use technically perfect, undamaged side guards which lock

securely into place!!

 Before using the safety sides, assess and take into consideration

the clinical condition and particular physical build of the resident:

o For example, if the resident is extremely confused or very restless,

avoid using safety sides as far as possible and make use of
alternative safety measures such as posey belts, restraint sheets,
etc.

o For especially small, frail residents, additional protective

measures for reducing the space between the bars on the
safety sides may be necessary. In these cases, use safety side
foam covers (accessory), posey belts, etc. This is the only way to
effectively guarantee patient safety and reduce the risk of the
patient becoming trapped or slipping through the bars.

 Only use suitable mattresses (not too soft) complying with DIN

13014 with a volume weight of at least 40 kg/m³ and dimensions
complying with the specifications in the instruction manual for
the bed (in the Chapter "Accessories"), to prevent endangering
patients through trapping or suffocation.

 If thicker special mattresses are used (for prevention or therapy),

such as mattresses to prevent pressure sores, an effective safety
side height of at least 22 cm above the non-occupied mattress
must be guaranteed.
If this requirement is not met, the operator is responsible for
taking any additional measures, or other measures he considers
suitable, based on his own risk assessment in view of the clinical
condition of the patient, and in view of the characteristics of the
special mattress, such as additional safety systems for the
patient, regular and more frequent monitoring of the patient or
internal instructions for users.

Instruction Manual for Care Bed Libra

Page 48 -

 The patient’s risk of falling can be lower:

o The smaller and more settled the patient is
o The softer the mattress is (the patient sinks deeper into the

mattress)

 Lock the operating functions for the patient on the handset if the

patient is liable to an increased risk of entrapment during backrest
and thigh rest adjustment when the safety sides are raised,

Otherwise there is a danger of limbs being crushed or trapped
between the safety sides if the patient inadvertently activates the
handset. The effectiveness of the safety sides can also be reduced if
the mattress base is raised to a high level.

4.5.3 Operation of split safety sides *

Position as delivered Raising the safety side

Raising the safety sides at the head end

 Grasp the middle of the top safety side bar  and pull the safety side bar

upwards as far as it will go. Both ends must audibly click into place.

 Repeat the procedure on all other safety side bars.

Raising all safety sides

The occupant is not sufficiently protected from falling out of bed if
only the safety sides at the foot end of the bed are raised.

Therefore only ever raise the foot-end safety sides if the head-end
safety sides are also raised.

Maximum protection for the occupant can only be achieved this
way, as with full-length safety sides.

5 Cleaning and Disinfection

This bed cannot be machine washed and not suitable for
cleaning in a decontamination unit. It is suitable only for
manual cleaning and disinfection. To maintain the lifespan
and functionability as long as possible, you must observe the
advice in this chapter.

5.1 GENERAL INFORMATION ON CLEANING AND DISINFECTION

Cleaning is the most important measure and requirement for a successful
chemical disinfection.
When the bed is occupied by the same occupant, routine cleaning of the
bed is generally sufficient. Disinfection of the chassis is only necessary when it
has been visibly contaminated with infectious or potentially infectious
materials (blood, stool, pus) or, if in the presence of an infectious disease,
under doctor’s orders.

Before an occupant change, the bed must first be cleaned and disinfected by
wiping!

Before cleaning or disinfecting:

 Unplug the transformer unit cable and store the mains plug so

that it does not come into contact with water or other cleaning
solutions.

 There must be no external damages visible on any of the

electrical components. Not following this can lead to water or
cleaning solutions leaking into the electronics and causing
malfunctions or damages.

 Before restarting the transformer unit, ensure that the electrical

contacts are free of any remaining moisture.

 The electrical components must not be cleaned with a water

jet, a high pressure cleaner or other similar device! Clean only
with a moist cloth!

 If you suspect that water or any other form of moisture has

penetrated the electrical components, pull the transformer unit
plug out immediately or do not plug it into the socket. If
already disconnected from the mains supply, make sure it is not
plugged in again. Report this immediately to the operator
responsible.

Failure to follow this safety advice could result in considerable
damage to the equipment and lead to subsequent malfunctions!

Instruction Manual for Care Bed Libra

Page 63

5.2 CLEANING AND DISINFECTION INSTRUCTIONS

 Remove bed linen and send it to the laundry service.
 Clean all surfaces, including the slatted bed frame and mattress base

made of synthetic or metal slats, with a mild and environmentally
friendly cleaning agent. This also applies for the handset.

 If the bed has been visibly contaminated with infectious or potentially

infectious materials, the bed should be subsequently disinfected by
wiping with one of the disinfection media approved by the DGHM
(Deutsche Gesellschaft für Hygiene und Mikrobiologie, German Society
for Hygiene and Microbiology) which is suitable for the corresponding
surfaces. The same applies for all beds with occupants who have
notifiable diseases according to § 6 of the Infektionsschutzgesetz (IfSG,
Protection against Infection Act), bacterial infections, or infections with
multiple-resistant pathogens (e.g. MRSA, VRE), as well as all beds in
intensive care stations and infectious disease clinics. For all disinfections,
the concentrations given in the DGHM list must be observed.

 Disinfection of the castors is only necessary when they have been visibly

contaminated with infectious or potentially infectious materials.

Continuous disinfection is only necessary in hospitals when an
occupant has a multiple-resistant pathogen (e.g. MRSA).

Instruction Manual for Care Bed Libra

Page 64 -

5.3 INSTRUCTIONS FOR THE USER AND EXPERT

In order to ensure that cleaning and disinfection are properly conducted, we
recommend that users and trained staff are appropriately instructed.

When providing instruction, observe the following points:

 A clean bed must be transported in such a way that it will not become

dirty or contaminated.

 Staff should be informed of the special measures required for cleaning

and disinfection and should carry out the procedure in a reliable
manner (the operator should specify the operational procedures or the
individual procedural steps). Care must be taken that only disinfection
agents approved by the DGHM (German Society for Hygiene and
Microbiology) are used, and that these are used only in the DGHM
approved concentrations.
The disinfectant must be suitable for the relevant surface.

 For this activity, the expert should be provided with disposable aprons

and gloves which are impermeable to fluids.

 For the cleaning treatment, only fresh, clean cloths may be used which

are subsequently sent to the laundry service.

 When cleaning/disinfecting work has been completed, the staff must

disinfect their hands before carrying out other tasks.
An appropriate dispenser of hand sanitizers (with lifting dispensing
device) should be included in the equipment of the staff.

 The immediate cleaning of the bed on site has the advantage that no

“dirty” beds or bed components come into contract with clean beds.

In this way, the transfer of potentially infectious germs which may be
found on the used chassis is prevented.
A transfer of germs in terms of a nosocomial infection can be safely
avoided by consistently and thoroughly following these
recommendations.

 When the bed is not immediately reused, it should be stored (covered)

in such a way that it is protected from dust, inadvertent dirt and
contamination.

Instruction Manual for Care Bed Libra

Page 65

5.4 CLEANING AND DISINFECTION AGENTS

Pay attention to the following recommendations to ensure that the bed
functions and usability are preserved as long as possible:

 Do not use scouring agents, care products for stainless steel

and abrasive cleaning agents or scouring pads.
These substances can damage the surfaces.

 Cleaning and decontaminating agents must have a pH value

of 5 to 8 at the specified concentrations.

 The chloride content of the solutions prepared for use must not

exceed 100 mg/l.

 We recommend (damp) wipe cleaning. When selecting

cleaning agents, ensure that the ones chosen are mild (gentle
to skin and surfaces) and environmentally friendly. A standard
household cleaner can generally be used.

 Ensure that after cleaning / disinfection no residues remain on

the surfaces of the bed. Otherwise the surfaces may become
damaged in the long term in these areas.

 Despite the excellent mechanical resistance, scratches,

markings, etc., which permeate the entire coating should be
resealed using a suitable repair medium to prevent the
penetration of moisture. For further information, consult
STIEGELMEYER or a specialist of your choice.

Instruction Manual for Care Bed Libra

Page 66 -

 As a rule, aldehyde-based disinfection media have the

advantage that they have a wide range of impact, a
relatively low protein effect and are environmentally friendly.
The main disadvantage of these agents is their potential to
cause allergies and irritation.

 Glucoprotamine-based formulations do not have this disadvantage

and are equally effective, although most are somewhat more
expensive.

 Disinfection media based on compounds which could potentially

release chlorine may be corrosive for metals, synthetics, rubbers and
other materials over longer contact periods or when concentrations
are too high. Furthermore, these media have a higher so-called
protein effect, are mucous membrane irritants and demonstrate poor
environmental compatibility.

 For disinfection by wiping, most cleaning and disinfection agents

usually used in hospitals or care facilities, such as cold and hot water,
detergents, alkaline solutions and alcohols, can be used.

 These agents may not contain any substances that could change

the surface structure or the adhesive properties of the plastic
materials.

 The choice of cleaning agents and disinfectants available on the

market may change from time to time. Stiegelmeyer therefore
routinely tests the most commonly used materials for compatibility.
The most up-to-date list of cleaning agents and disinfectants can be
obtained on request.

Instruction Manual for Care Bed Libra

Page 67

5.5 HANDLING CLEANING AND DISINFECTION AGENTS

 Pay attention to the exact dosage! We recommend the use of

automated dosing instruments.

 Always prepare solutions with cold water in order to avoid the

formation of vapours which are mucous membrane irritants.

 Wear gloves, in order to avoid direct skin contact.
 Do not keep prepared surface disinfection solutions in open containers

with floating cleaning cloths. Be sure to cover all containers!

 Use sealable bottles with pump dispensers for moistening the cleaning

cloths.

 Ventilate the room after the disinfection has been completed.
 Disinfect by wiping; do not disinfect by spraying! When spraying, a large

portion of the disinfection medium is released as spray and could be
inhaled.

 Furthermore, the wiping effect plays a significant role.
 Do not use alcohols for the disinfection of large surfaces.

6.5 REPLACEMENT OF ELECTRICAL COMPONENTS

Danger of death due to electric shock!

 Before commencing any work, unplug the transformer unit

cable from the electrical socket!

 Any work and/or repairs to the electrical drive system may

only be carried out by the Stiegelmeyer service engineers,
the drive manufacturer or qualified and authorised
electricians in compliance with all the relevant VDE and
safety regulations!

 Only dismantle the control unit and electrical motors when

the bed is in the home position (mattress base is in the
horizontal position). Otherwise there is the risk of being
crushed due to falling parts of the mattress base.

 On no account should the user attempt to rectify

malfunctions in the electrical system!

- All the drive components are maintenance-free and must not

be opened. In the event of a malfunction, the corresponding
components should always be replaced in full!

- When replacing individual components, always make sure that

all plugs are equipped with undamaged O-rings. The plugs
have to be aligned in accord with the sockets of the control
unit and have to be plugged in all the way. Finally the plug
cover has to be properly fastened again. Only this ensures
tightness and efficient function. Only this ensures tightness and
proper function.

6.5.1 Plug assignment of the control unit

All plugs are connected to the control unit. To prevent the plugs from being
inadvertently disconnected, they are secured with a cover. When necessary,
this device can be carefully lifted off using a screwdriver.

 1 = Handset
 2 = Lift motor foot section (white)
 3 = Lift motor head section (blue)
 4 = Thigh rest (yellow)
 5 = Backrest motor (black)
 6 = Battery compartment (2 x 9 Volt batteries)

Instruction Manual for Care Bed Libra

Page 77

6.5.2 Connection of a reading lamp (optional equipment)

The reading lamp is installed as follows and then connected with the plug­power pack to an external 230 Volt outlet.
Please read the separately enclosed instruction manual on how to operate it.

Step 1

Step 2

Insert the plastic adaptor securely

into the sleeve for the patient lifting

pole at head end (left or right).

Insert the upright pole of the lamp

with the connecting cable from

above into the plastic adaptor and

press it down until it is firmly in place.

6.5.3 Control unit replacement

 Unplug the transformer unit plug from the socket.
 Carefully unscrew the plug cover on the control unit off using a Philips

screw driver.

 Mark the plug positions to avoid switching them when re-assembling

(see Chapter 6.5.1).

 Unplug all plugs / connecting cables from the control unit.
 Remove the old control unit from its holder.

o Remove the two clamps on the holder.

 Place the new control unit in and fasten it with the help of the clamps.
 Insert all plugs again into the corresponding outlets (see Chapter 6.5.1).

o Pay attention that the plug O-rings are all present and undamaged. It

seals the plug within the control unit.

 When routing the handset cable, ensure that it cannot be damaged by

any moving parts of the bed.

 Put the plug cover back in place. This prevents all the plugs from being

pulled out of the control unit.

 Lower the bed completely down or raise it up. That allows the bed's

control system to detect the intermediate stops.

 After this, check the power adjustment functions according to Chapter

6.2!

6.5.4 Motor replacement

 Unplug the transformer unit plug from the socket.
 Remove the faulty motor.

o For lift motors: Remove the safety disk and extension bolts.
o For upper thigh and back motors: Remove clevis pins.

 Loosen the plug-in cable connection on the control unit.
 Reinstall the new motor in exactly the same way.
 To prevent the motor bolts from working loose and causing potentially

hazardous sudden changes in the position of the bed, always ensure that

you fit new safety caps (“Starlock”; available from Stiegelmeyer service

department) and do not refit the old safety caps that you removed.

 After this, check the power adjustment functions (see Chapters 6.2).

6.5.5 Decommissioning

If the bed is not used for an extended period, please follow the instructions
below for taking the bed out of service safely and ensuring ideal conditions
for its re-use.

 Clean and disinfect the bed (see Chapter 5) and cover it as a protection

against new contamination.

 Adjust the mattress base to a flat home position at its lowest level.
 Lock the electric adjustment functions to prevent them from being

activated accidentally or by unauthorised persons.

 The bed must be braked.
 Pay attention to the ambient conditions required for storage (see Chapter

9.3).

8 Accessories

A wide range of accessories is available for this bed, and we are continually
extending this range

Risk of Injury

 Efficient and safe operation combined with maximum

protection of patients can only be guaranteed if original
Stiegelmeyer accessories are used which are designed for the
relevant model of bed.

 In addition to the information given in this instruction manual,

please also refer in this respect to the separate special
instruction manual supplied with certain accessories.

 Make sure that the arrangement of accessories does not

produce any crush or shearing zones for the resident when the
backrest and leg rest are adjusted.

 If this cannot be guaranteed, the user must safely prevent the

occupant from adjusting the backrest and leg rest.
Place the handset out of reach (e.g. at the foot end of the
bed) or lock the handset adjustment options.

Preventing damage to property

In order to minimise any potential damage to property, please
read and refer to the following general information on selecting
and attaching accessories:

 Attach accessories only while these are required and only at

the positions intended for them in such a way as to avoid
damaging the surfaces of the bed and accessories.

 Avoid, for example, chafing or unprotected attachment of

metal clamps on coated or varnished surfaces.

 Please note when moving the bed that attached accessories

may extend beyond the height, width or length of the bed
and so may collide more easily with door frames, corners of

walls and other obstructions.
In the case of very long accessories such as patient lifting poles,
infusion poles, extensions, mobilisation aids, etc., avoid applying
high lateral forces, such as are possible with this bed design,
such as by manoeuvring the bed using the infusion pole. This
will prevent overloading the fixing points.

Lists of accessories can be obtained from Stiegelmeyer and their sales
partners, quoting the bed model.
