1.4.General safety instructions

CAUTION!

Refer to user’s manual!

Please read safety instructions!

WARNING! – Serious injury can be caused when moving powered parts of the bed. Make absolutely sure that there are no parts of the body poking through the safety frames during electrical operation. Ensure without fail that there are no people, pets or objects beneath the bed.

WARNING! – Increased safety measures are necessary when the bed is being used … 1. … by a child under 12 years of age,

2. ... by a person with reduced mental faculties, 3. ... for psychiatric purposes.

WARNING! – Automatic mode should not be selected when the bed is being used … 1. … by a child under 12 years of age,

2. ... by a person with reduced mental faculties, 3. ... for psychiatric purposes.

WARNING! – In order to avoid falls, always return the bed to lowest position after each use of the adjustment functions. Make absolutely sure that

a)the bed is in lowest position before getting into or out of it, and

b)the brakes are applied.

WARNING! – Safety frames only mark the limits of the bed. Other appropriate measures must be used to restrain patients.

WARNING! – Children under 12 and people with reduced mental faculties may only occupy Völker beds when the safety frames are covered by protective covers. Risk of injury. Refer to user’s manual.

WARNING! – In order to minimise risk of injury, the following permitted mattress sizes must be strictly observed. If you are not using Völker mattresses, please contact your Völker authorised dealer.

1.6. Before using the bed for the first time

Before the bed is put into service for the first time, this user’s manual must be closely read by all those responsible for nursing care.

Before the bed is put into service for the first time, it is absolutely essential to carry out a functional test as described in Chapter 8.

Before first use, carers must receive detailed instructions in the operation of the bed. In addition, carers must be made fully aware of potential dangers that can arise in spite of the correct operation of the bed (see Chapter 4).

1.7.Checking the operational safety and condition of the bed

Before putting the bed into service, it is essential to make absolutely sure that it is in good working condition and safe to use. This test must not only be carried out before first use, but continuously throughout the service life of the bed. If necessary, the bed must be tested daily or after each shift to ensure that its use does not endanger anybody. To reduce maintenance to a necessary minimum, the bed should be cleaned, disinfected and tested as soon as possible after each use so that it can be used again without delay or risk (see Chaper 8, Functional test). Please note that preparation in a cleaning plant offends against this principle (see Chapter 9).

In cases of malfunctioning, it may be necessary to transfer the patient to another bed.

Edition: 2002 May.-C

Völker hospital bed		User’s Manual	Model S 960-1

1.8.Position of the hospital bed – Danger of falling out of bed

In the case of unsupervised patients, we recommend that the bed is put into its lowest position to minimise the risk of injury due to falling out of bed. In other cases, it should be put at a height proportionate to the size of the patient.

1.9.Four-castor central braking system – Caution! Risk of accident

Unless in transport, the brakes must always be applied so that patients can use the bed as a support when accessing or exiting it. Serious falls can result through an unbraked bed rolling away. After applying the brakes, check that the bed is really immobile, ie that the brakes are fully applied to all four castors.

Height adjustment – Risk of entrapment between bed-frame and chassis

When adjusting the bed, make absolutely sure that no limbs, bedding or other objects are situated between the bed-frame and the chassis.

1.10. Safety frames – Risk of entrapment

In the case of patients whose physical or mental state may be felt to call for the use of safety frames to protect them from falling out of bed, the following safety measures must be observed at all times:

1.Safety frames may be operated only by carers instructed in their use.

2.Make sure safety frames – or elements of them – are either fully raised and locked or fully lowered.

3.During the electrical adjustment of the mattress-frame, make sure that the patient is not touching the safety frames. Also make absolutely sure that no limbs are poking through the frames.

4.If the safety frames are being used to protect a child or a person whose physical state may make their use appropriate, then make sure that the handset is out of reach. We also recommend the use of safety frame covers.

Failure by carers to obey these safety rules may cause hæmatoma or other injury to hands, knees, fingers, feet, shins and hips through entrapment.

1.11.Cleaning and disinfection

Risks can arise through the incorrect cleaning and/or disinfection of the bed.

Völker hospital bed		User’s Manual	Model S 960-1

1.12. Service and maintenance

The S 960-1 bed requires very little maintenance. All moving parts of the lifting gear, mattress-frame drives and safety frames are permanently lubricated during manufacture. None of these parts need relubrication when the bed is correctly used and cleaned. The manufacturer assumes, however, that beds are regularly inspected and damage such as worn parts, loose screws or fractures are immediately put right. For further information, please see the maintenance section of this user’s manual.

Edition: 2002 May.-C

Page 15 of 80

Völker hospital bed		User’s Manual	Model S 960-1

repositioning of leg section. Full horizontal lower leg position possible by putting upper leg section at 75°.

Mattress displacement device according to GPNA:

The mattress displacement device or length compensator automatically shifts the fulcrum of the back section 15 cm backwards when it is being raised. This stops patients sliding down the bed and concertinaing against the footboard, especially when both back and leg sections are being adjusted simultaneously. The compensator creates a kinæsthetic space that stimulates patient mobility.

Fast-release facility:

The back section can be rapidly lowered (CPR) as required simply by releasing the retaining mechanism on the mattress-frame. The facility is fitted with a cushioning device to ensure jerk-free descent. No resetting is needed to reinstate normal back section operation after fast release.

Safety frames:

The S 960-1 is equipped with split safety frames on both sides of the bed that are fully integrated into the mattress-frame. When raised, they both protect the patient and serve as a support when accessing or exiting the bed. When not in use, they are pushed out of sight beneath the mattressframe. This facilitates the unobstructed fitting of accessories and the use of a bed-jack even when the bed is in lowest position. During mattress-frame adjustment, the safety frames are repositioned automatically. To use, pull the safety frames horizontally out of their locations. To protect the patient, they are then raised either singly or together and locked into position. Complete patient protection is achieved by raising all four safety frame. Thanks to their exceptional stability, they can also by used as a depository for bedding or as support for special therapeutic positioning, eg physiotherapy. This stability also stimulates patient mobility by providing reliable support when sitting up and exiting the bed. As in the case of many S 960-1 functional features, here too the variety of possible configurations pays off. Hence the back section can be used to help the patient sit up, and the telescopic jack to put the bed at the ideal individual height for exiting it. As an option, the height of the safety frames can be increased by 12 cm, eg when using special mattresses. In this way, the minimum required height of 22 cm between mattress and the upper edge of safety frames can always be maintained. During transport, the safety frames – in whatever position – act as robust anti-impact side-fenders. In the case of the S 960-1, this avoids the usual damage to door-frames or to the safety frames themselves.

Lengthening the bed:

An extension piece mounted on telescopic slides enables the bed to be lengthened by 20 cm without removing the footboard (optional). The extension piece is securely fixed to the lower leg section of the mattressframe and is simply pulled out of its location and folded up, as required.

Edition: 2002 May.-C

Page 16 of 80

Völker hospital bed		User’s Manual	Model S 960-1

Fast removal of headand footboard:

The headand footboard can be removed as required by means of a fastrelease fixing built into the bed-frame. Easy handling at all times is ensured by the use of plastic connectors with an exceptionally long service life. As the connectors are not subject to crevice corrosion, they do not split and hence tend to clamp even after being washed many times.

Fixings for trapeze pole and drip-feed stands:

Push-in sleeves for trapeze poles and drip-feed stands are provided on the outside of the headend of the bed.

Fixings for accessories and therapeutic appliances:

Adapters fitted to the full-length slide bars on each side of the bed accept therapeutic appliances and care accessories. These can be positioned as required simply by pushing them back and forth along the slide bar. Easy positioning is guaranteed independently of bed height and safety frame configuration.

Wall buffer wheels:

In addition to the safety frames acting as side-fenders during transport, there are also horizontal buffer wheels on all corners of the bed and two further vertical buffer wheels at the headend.

Accessories: Völker offers a wide range of accessories for its beds.

You will find the complete range in our hospital accessories brochure.

Electrics and

control: Processor control, integrated energy storage device (battery), all functions operable without mains power supply, 230 V mains connection on battery charger, from there and within bed safe low voltage (24 V) – no electrosmog.

Carers’ keyboard with all mattress-frame positions and height adjustment, plus trendelenburg/reverse trendelenburg function, activation/deactivation of patient’s handset functions, including graphic display. Functions that stimulate the autonomous mobility of patients, ie height adjustment and mattress-frame positioning, can be selected by patients themselves via separate handset (unbreakable; IP X5 as standard or IP X6 for decontamination plants).

Handset for patients with the following functions:

−	Back section	up/down
−	Upper leg section	up/down
−	Lower leg section	up/down
−	Height adjustment	up/down
−	Comfortable sitting position

Handset can be mounted to right or left, as required; an optional handset connection is also available on safety frame.

Operational readiness independently of mains supply is ensured by means of a rechargeable battery. An integrated power-saver (eco-mode) means that the bed remains operational over long periods out of service. In normal operation, the bed can be used for about 2 days with a fully-charged battery. When used as instructed, the service life of the batteries is at least 5 years. Spent batteries are returned to Völker for recycling.

The use of an external 400 mA charger and an internal energy storage device ensures that only safe low voltage current flows from the battery charger (in the socket) onwards. The bed is fitted with an infrared port for maintenance purposes

Cleaning: If required, a version of the bed can be supplied that is suitable for cleaning in decontamination plants. Follow the recommendations in brochure ZH 1/200 to ensure a long service life and functional efficiency.

All sub-assemblies are in stainless steel and hence require little maintenance. Inspection checks are only necessary at 12-month intervals. Bar-code and inventory number for technical inspections can be integrated. We also run training sessions for in-house technical staff, if required.

Warranty: 2 years warranty on construction and working assemblies.

Ecological

data: Fitted with a device (24 V safe low voltage, internal energy storage device) to hinder the formation of electrosmog.

All packing materials are removed on delivery and taken back free of charge. We also guarantee to take back the bed itself for ecologicallyappropriate utilisation/disposal.

Service life of hospital beds:

With the exception of parts subject to wear and tear, eg castors and electronic components, the bed has a service life of about 12 years providing that it is used, cleaned, serviced and repaired as instructed. Cleaning and/or disinfection in mechanical plants can reduce the above service life, depending on frequency.

3. Explanatory notes for carers

This documentation contains all information necessary for the normal operation of Völker hospital beds.

Völker accepts no guarantee claims whatsoever for damage, injury or accidents caused by carelessness, inattentiveness or the incorrect use of the Völker hospital bed. In this connection, the question of culpability is irrelevant.

If required by the customer, Völker or its representative is willing to give carers basic training in the operation of the bed.

The participation in such training sessions for carers must be confirmed with name, date and signature on a form specifically intended for this purpose, which must be counter-signed by Völker or its representative.

The safety regulations contained in this documentation – more especially those in Chapter 2 – must be strictly obeyed and adhered to at all times.

The conscientious observance of the safety regulations, modes of behaviour and instructions described in this manual guarantees the safety of carers, patients and others.

Please note that functional features marked as special equipment are only available in beds so equipped.

5. Operational units

General operating instructions

5.1.1. Safety class

The bed conforms to Safety Class II and Type B according to DIN EN 60601-1 and VDE 0750, Part 1.

The bed is fitted with a connection for a voltage compensator.

The electricity supply via the charger is safety insulated and is equipped with a fail-safe transformer that charges the battery with electrical energy.

5.1.2. Operating interval

The maximum operating interval of the electrically-powered bed functions is given on the bed (name plate) and/or in the technical data sheet as “Int 2 min / 10 min”, ie each bed function may only be continuously operated for a maximum of 2 minutes in any period of 10 minutes.

Automatic safety devices kick in if the maximum operating interval of 2 minutes is repeatedly or markedly exceeded, leading to the power drives cutting out. The bed must then be inspected and tested!

An integrated time-lag device hinders the accidental or brief operation of the keyboard and consequent movement of the mattress-frame. This device requires that users consciously press and hold down the relevant key. Functions then kick in after a time-lag of ca. 0.5 seconds.

5.1.3. Batteries

When fully charged, the bed batteries have a theoretical capacity sufficient to power all bed functions with a working load of 170 kg continuously for ca. 15 minutes. After that, only the emergency functions (trendelenburg/reverse trendelenburg) and booting can be carried out.

If the bed is put into storage with disconnected charger, then self-discharge through leakage leads to the exhaustion of the battery!

Totally discharged batteries can be so badly damaged as to necessitate their premature replacement!

In order to achieve a long service life, the correct treatment of both the battery and the charger is absolutely essential!

5.1.4. Built-in safety cut-out

The bed is fitted with a built-in electronic safety cut-out that hinders the overloading of the drives. In the event of overloading, the drives are automatically switched off. For safety reasons, thereafter electrical adjustment is only possible in the opposite direction.

This adjustment in the opposite direction is also required if the drive is already in end-position!

After having been moved in the opposite direction, normal adjustment of the mattressframe is automatically reinstated.

Puting bed into service for the first time (initiation)

Location

The bed is authorised for use solely in dry rooms (Technical data sheet). A mains power supply socket and, if required, a voltage compensator connection must be available in the room in which the bed is to be used.

The bed is mobile without the need for auxiliary transport equipment.

The bed may only be moved on firm surfaces. Moving the bed over obstacles greater than 2 cm in height is prohibited. Gradiants may not exceed an angle of 10°.

The bed is supplied complete and can be set up without first having to remove transport equipment.

5.2.1. Mechanical initiation

•Push the headand footboards supplied into the corner connectors of the bedframe.

(see 5.3.10)

•Handset connection

There is a socket for the handset on the LH and RH face of the central bearer below the seat section. Pull off the protective cap and insert the handset plug. Make sure that the socket that is not in use always remains sealed with the protective cap!

If the handset is removed from the bed, then the socket must immediately be resealed with the protective cap (maintenance of safety standards IP-X5 or IP X6).
