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
Copyright Squirrel Medical® 2017 - E&OE
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
In an emergency, pull CPR Strap to open
valves and quickly deflate mattress

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.
Excessive heat can damage the cover

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.
