5.4 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 ‘Power 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.

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 does not sound, take the pump out

of use until it has been serviced.

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 Diamond 8900 Pump and no air

is escaping. The ‘LOCK’ on the connector should be engaged.

• 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.

Nov 2018

Issue 1.06

Page 19 of 40

5.5 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.

Press down to seal before each use

In an emergency, pull CPR Strap to open valves and quickly deflate mattress

⚫

Page 20 of 40

5.6 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 Tube Set connector from the pump and attach the transport cap into place.

1. Align the red arrows and locate the Transport cap over the Tube Set Connector.

2. Pressing the Transport Cap tightly against the Tube Set Connector, twist them anti-

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 Diamond 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 Diamond MRS, use detergent/disinfectant on a damp cloth only.

Do not use phenol-based disinfectant solutions.

7.2 Cleaning the Mattress

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

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 Diamond 8900 pump from the main

power supply.

2. Use the Transport 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.

Page 24 of 40

7.2.1 Disinfecting the Mattress

If the Mattress has been soiled or stained, a solution of 10,000ppm chlorine releasing

agents such as bleach may be used to remove body fluids. Overuse of these solutions may

compromise the longevity of the Mattress and/or Mattress Cover. Ensure that all high

concentration cleaning agents are rinsed with fresh water from the mattress only.

7.2.2 Laundering Mattress Cover

The Mattress Cover can be removed and machine washed if required.

Unzip and remove the PU top cover from the mattress.

The Mattress Cover all around the perimeter of the Mattress and wash according to the

instructions below. Always ensure that the Squirrel Diamond MRS is cleaned prior to

transfer to another location i.e. for repair.

7.3 Cleaning the Pump

▪ Disconnect the Diamond 8900 pump from the main electricity supply. ▪ Wipe all surfaces of the Pump 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.

▪ Wipe down all surfaces of the Pump with mild detergent on a damp cloth ▪ Dry all surfaces with a lint free cloth. ▪ Check for damage such as cracks to the Pump housing. ▪ Allow all cleaned parts to air dry thoroughly before replacing mattress cover and

store in a clean area.

7.3.1 Disinfecting the Pump

▪ Ensure the Pump is unplugged before commencing the decontamination process. ▪ In cases where there has been contact with bodily fluids, e.g. blood, wipe down the

external surfaces of the pump with a soft cloth dampened in a concentration of

NaDCC increased to 10,000 parts per million (1%) of available chlorine.

▪ Dry with a paper towel or dry soft cloth ▪ Allow all cleaned parts to air dry thoroughly before using or stowing the Pump. ▪ Staff should refer to the safe work practice sheet on the use of workplace

equipment contained in the department safety statement.

Fault (Contd.)

Possible Causes (Contd.)

Solutions (Contd.)

Audio Alarm

sounding at

regular intervals

▪ Leak in System ▪ Punctured Mattress ▪ Alarm Mute button

pushed

▪ Is the CPR valve is fully sealed? ▪ Has the mattress or Tube Set been

punctured?

▪ If ‘Silence Alarm’ has been pushed, the

alarm will continually sound again until

the underlying problem has been

resolved. Check for error lights.

If all points in the Table above have been addressed but the fault persists, or a puncture has been found, then the Diamond MRS will require servicing. Take the Diamond 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.

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

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 may 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 less than 3 V/m.
