prevention of pressure ulcers and must be used with sound clinical judgment.

5.5 Alarms & Indicators

There will be an audible alarm sound for the following reasons:

Power Failure Alarm

In the event of a power failure an audible alarm will sound.

This will be accompanied by the red ‘Failure’ light flashing on the pump control panel.

Check that:

• The power socket has not been turned off.

• The plug has not been pulled out or partially out of the power socket.

• There has not been a general power cut to the building or the patient’s bedroom.

Restore the power by replacing the plug in the socket.

Note - when power is restored the pump will automatically turn itself back on and starts to

re-inflate the mattress to the previous settings.

Page 16 of 40

The Power Failure Alarm must be tested at least once per year, and also after

any prolonged period of storage before commissioning the Pump for use.

TO TEST: With the Pump powered and operating, switch off at the wall socket. If

no alarm sounds, leave the pump running for 60 minutes to recharge internal

batteries, then repeat the test. If the alarm still fails to sound, inform service

personnel and schedule the Pump for service immediately.

NOTE: If a replacement pump or alternative mattress system is not available, the

pump can continue to be used providing a qualified engineer has been called to

service the pump and suitable risk assessment has be carried out. All other pump

features and alarms will continue to operate, but there will be no warning of a power

failure!! Regularly check the pump is powered, and exercise increased caution while

using.

Low Pressure Alarm

In the event of low pressure within the mattress an audible alarm will sound.

This will be accompanied by the Low Pressure light flashing on the pump control panel.

Check that:

• The tube set connector is securely located into the Dormir Digital 8535 Pump and

no air is escaping. Check there are two ‘O’ Rings present on the connector if air is

escaping.

• The CPR valve on the tube set is held firmly in place and that no air is escaping.

If the mattress continues to indicate low pressure, it will be unable to alternate

the pressure in the cells. This could lead to a pressure ulcer. The patient should

be transferred to an alternative operational MRS whilst the mattress is

inspected and/or repaired.

5.6 CPR Valve

In the event of cardiac arrest:

The CPR is a mechanism that allows for the rapid

deflation of the mattress. It is within the tube set. It can

be identified by a bright yellow nylon Strap that is

connected to a valve on the Tube Set.

If the mattress is to be deflated pull the yellow CPR Strap

firmly ensuring that air flows freely from this area.

March 2019

Issue 1.9

Page 17 of 40

5.7 Mattress Transfer Mode

This mode allows for some air to be sealed inside the mattress base allowing the mattress

to be transferred to different locations (e.g. for cleaning and servicing) without deflating.

Do not use mattress transfer mode with a patient in the bed.

The transfer mode must not be used if a patient is using the mattress.

Disconnect the male tube set connector from the pump and clip the transport cap into

place.

Press down to seal before each use

7. Cleaning and Decontamination

7.1 Cleaning Precautions

Always clean and disinfect the Pump and the Mattress before use, in

particular when assigning new patients to reduce the risk of any possible

cross infection.

Before beginning any cleaning or disinfecting procedure, make sure you are

wearing suitably protective clothing and gloves to prevent against skin

irritation or other adverse skin reactions.

Always dispose of cleaning agents in compliance with any instructions given

with the cleaning agent and facility policies.

Always dispose of all cleaning agents & waste in accordance with company

procedures.

Never use abrasive cleaning agents or pads on the Mattress or Pump, doing

so will damage the Mattress Covers and the finish of the Pump.

If disinfection procedure involves large scale spaying of flammable

disinfectants, special precautions should be taken to prevent against the risk

of fire or explosion.

Always unplug the Pump from the main electricity supply before carrying out

any cleaning, disinfecting or maintenance on the Dormir Digital MRS and

keep the plug away from all liquids.

Never use any type of water or steam high pressure cleaner, jet or spray on

the Dormir Digital MRS, use detergent/disinfectant on a damp cloth only.

Do not use phenol-based disinfectant solutions.

Never attempt to clean a Dormir Digital MRS while there is a patient

occupying it.

Page 20 of 40

7.2 Cleaning the Mattress

Whilst cleaning the Mattress, it is always good practice to look for signs that the Dormir

Digital MRS may have been damaged or is requiring service. Such indicators include (but

are not limited to) rips or tears, air bubbles appearing as you wipe Air Cells, signs of fluid

ingress into the interior of the Mattress or damaged components.

1. Inflate the mattress base and disconnect the 8535 pump from the main power

supply.

2. Use the mattress transfer cap to seal air within the mattress base. An inflated

mattress base will make the inspection and cleaning process easier.

3. Use a soft cloth soaked in a solution of mild detergent and warm water at 40°C to

wipe down all the mattress surfaces clean, including the protective sleeve to the

pump.

4. It is recommended to begin with the underside first and finish with uppermost

surface, and work systematically down the tube set towards the Connector.

5. Wipe all surfaces of the Mattress with a solution of sodium dichloroisocyanurate

(NaDCC) at a concentration of 1,000 parts per million (0.1%) of available chlorine

using a soft cloth.

6. Unzip the top cover and continue to clean the tube sets and air cells within the

mattress. Once wiped clean as far as possible, remove the Transport Cap to deflate

the Air Cells and continue to clean the base of the mattress interior.

NOTE When the Mattress Cover has been damaged or nears the end of its life, the white

lining on the inside of the Cover will show signs of staining or soiling. If it has been stained

the Mattress Cover needs to be replaced. The Mattress must be fully decontaminated

before the Mattress Cover is replaced.

7. Wipe away any residue detergent solution from all parts using a soft cloth soaked in

only warm water, and dry with a paper towel or second dry soft cloth.

8. Allow all cleaned parts to air dry thoroughly before replacing mattress cover and

store in a clean area.

9. Check the foam in the mattress base. If this has been soiled then it should be

replaced .The mattress must be decontaminated before the foam is replaced

Cross contamination is a major hazard to patients. The Mattress Cover should

therefore be laundered in between patients. Spare covers are available to

ensure that a Mattress is never out of use.

If all points in the Table above have been addressed but the fault persists, or a puncture has been found, then the MRS will require servicing. Take the Dormir Digital MRS out of use until it has been serviced.

It is important that the mattress and patient are checked frequently to ensure that there is

sufficient air to safely support the patient. If there is insufficient air to support the patient

the patient should be transferred to another support surface.

The mattress will not alternate its pressures without power. This can lead to

pressure ulcers so additional clinical support may be required

If the mattress continues to indicate low pressure, it will be unable to alternate

the pressure in the cells. This could lead to a pressure ulcer. The patient should

be transferred to an alternative operational MRS whilst the mattress is

inspected and/or repaired.

Portable and mobile RF communications equipment should be used no closer to any part of the PL-8900 PLUS including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.

Recommended separation distance:

d = 1,2 √P d = 1,2 √P 80MHz to 800 MHz d = 2,3 √P 800MHz to 2,5 GHz Where P is the maximum output power rating of

the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in metres (m).

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the compliance level in each frequency range.b

Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and

land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the PL-8900 PLUS is used exceeds the applicable RF compliance level above, the PL-8900 PLUS should be observed to verify normal operation. If abnormal performance is observed, additional measures my be necessary, such as re-orienting or relocating the PL-8900 PLUS.

b Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.
