System installation

The following describes the procedures for setting up the system for the first time.
a) Remove all covers, sheets and mattress from the bed.

b) On a standard bed, position Mattress
Replacement on top of bed, printed top cover facing upwards and air hoses towards the base of the bed. Attach to the bed by securing the adjustable straps under each end of your bed. Ensure buckles are securely fastened and straps are pulled tight.

c) IMPORTANT: On a profiling bed, secure the side straps around the moveable sections of the bed base. DO NOT secure to the side rails or main bed frame – irreparable damage could be caused to the bed and mattress
d) Confirm there are no sharp objects in the immediate area which may risk damage to the Mattress Replacement.

Pump Unit Activation
a) Position Control Unit by hanging hooks over foot board of the bed or place unit on the floor under the bed.

b) Attach the air hoses through the use of the quick connector to the Control Unit. Ensure air  hoses do not kink between mattress, bed frame  and Pump Unit.

c) Plug the power cord into an electrical outlet with grounded AC power.
NOTE: Before inserting the plug into the outlet, make sure the voltage is compatible. Also make sure this product is well grounded.
d) Switch the power button on. Allow up to 40 minutes for full inflation.

e) The 8 pressure indicate lights will flash until the mattress is inflated and ready for patient use. Once ready, the weight setting will show a constant light at the 40kg weight setting.
Perform a “bottom out” test to ensure that patient is properly suspended. Slide your hand under the top cover along a deflated cell in the sacral (bottom) area. Secure sheets loosely enough to ensure they do not interfere with cell alternation.

Operation

NOTE: Always read the operating instructions before use.
General
This product is designed to provide  maximum comfort to patients. Make sure that you operate this product in a proper way optimizing its value. Here we provide some general information that you should be  aware of.

For products:

• DO NOT use another pump with different specifications unless instructed to do so by OSKA Care
• DO NOT change any component by yourself.

If there is need for replacement or repair, always contact OSKA Care
For patients:
When the pressure has been adjusted to a desired level of firmness, the patient can then lie on the mattress.
A firm surface will make it easier for the patient to transfer or reposition. Make use of the static mode function for this feature. To sit a patient up in bed, press the Seat Button to increase the pressure to have better support on sacrum area.

Hand check:
Check if the pressure is properly adjusted by sliding one hand between the air mattress and bed  frame to feel the patient’s buttock.
Users should be able to feel the space in between, and the acceptable range is approximately 25 to 40 mm (1” to 1-1/2”).

NOTE: Please follow instructions below for detailed operating procedure of each type.
Step 1 Turn on the power. A beep sound will begin the operation.
Step 2 The pump will enter into static mode when the power is initially turned on.
First it will inflate the mattress to 1015mmHg and then enter alternate mode.
If 10-15mmHg can not be reached within 30 minutes, the unit will stay in static mode and keep inflating. If 10-15mmHg still can not be reached within 40 minutes, the alarm will beep and its LED will come on.
Press the Alarm Mute button to mute the alarm. The alarm LED will continue flashing.
Press the Alarm Mute button again to re-enable the audible alarm.
Step 3 The alternating cycle time and pressure  level are set at 10 minutes and 30mmHg  initially. Select from the touch panel to adjust the cycle time and pressure level to
the patients specific requirements.
NOTE: Press the static mode button from the touch panel to provide a firm surface that makes it easier for the patient to transfer or reposition. The static mode can support the patient by keeping the mattress from bottoming out when the patient is in a sitting position. The static  mode will revert back to alternating  mode after 20 mins.
Step 4 During normal operation, the unit will monitor pressure. If the mattress pressure  is lower than the set pressure, the pump  will automatically inflate the mattress to the set level and then stop. The alarm will beep and its LED will come on to alert a low pressure condition.
Press the Alarm Mute button to mute the alarm. The alarm LED will continue flashing.
Press the Alarm Mute button again to re-enable the audible alarm.
Step 5 Press the Max Firm button to automatically inflate the mattress to the maximum level (65mmHg) for about 20 minutes. The pressure will return to a previously set level after 20 minutes.
In case there is a bad connection of tubing or any air leakage from the mattress, this will result in a low pressure condition, and it will activate the alarm within 1 min.
NOTE: For suitable pressure, please refer to page 8 for the hand check procedure.

CPR function
When there is an emergency requirement to perform CPR on the patient, press the CPR button at the head section of the mattress and disconnect the air hose from the pump to release the air quickly from the mattress.
Pressure set up
Users can adjust the pressure level of the air mattress to a desired firmness by themselves or according to the suggestion from a health care professional.
NOTE: It is recommended to press Max Firm on the panel when the mattress is first inflated. Users can then easily adjust the air mattress to a desired firmness according to the patient’s weight and comfort.
Low pressure warning
When abnormal pressure occurs, the Low Pressure indicator will come on. For some types of pumps, the alarm will be activated to alert of a low pressure condition. Check if the connections are secure and correctly installed according to the relevant instructions.
NOTE: If the pressure is consistently low, open the zipper and confirm that all of the hoses are properly connected. Then check for any noticeable leakage in any of the tubes. If necessary, contact your local dealer to replace any damaged tubes or hoses.

Cleaning
In this section, we describe the procedures to clean and decontaminate the pump. It is important to follow these procedures before using the system again.
The cleaning task is required at least once a week to maintain personal hygiene.
Pump Unit

• DO NOT immerse or soak the pump in any water or fluids.
• Check for external damage and move the pump to the cleaning area.
• Place the pump on a work surface and spray or wipe the outside of the case with quaternary ammonium solution.
• DO NOT spray any cleaning solution directly on the surface of the pump.
• DO NOT use a Hypocarbonate or Phenolic based cleaning solution as this may cause damage to the case. Allow the solution to  incubate for 10 minutes or accordingly as  stated by the cleaning product instructions.
• Wipe case with a clean cloth. Make sure all areas are clean (top and bottom, both sides).
• Spray cloth with cleaning solution and clean faceplate. DO NOT allow excess cleaning solution on faceplate or control panel. (If solution gets inside, damage will occur.) Allow surface to thoroughly dry after cleaning.
• After the pump is thoroughly cleaned and  dried, proceed to plug in the pump and test to  see if it runs normally.
• Unplug the pump and store with proper identification tag.
• Avoid long exposure to sunlight.

Mattress

• Brush off or wipe down all surfaces of the cover sheet with soap and water before wetting with any liquid disinfectant.
• Any obvious blood spots should be wet thoroughly with 1:9 Hypochiorite solution (1 part bleach to 9 parts water) and allow drying for at least 10 minutes. Then blot with a clean, damp cloth.
• Unzip the top cover from the mattress.
• Brush or wipe down all surfaces with soap and water before applying any liquid.
• Covers are immersed and soaked in disinfectant for the required incubation time.
• After pre-soaking, the cover is rinsed through a regular cycle in a washer with no soap then laundered with mild detergent (wash temperature 93°F/34°C, rinse temperature 78°F/26°C or on the coldest setting).
• Covers are aerated until they are fully dry. (Drying temperature range 90-120°F/32-49°C or on the coldest setting.)
• The air cells are unsnapped from one side and are sprayed on all sides with a disinfectant. Let it sit for the required incubation time and wipe down with a clean cloth. (Make sure to disconnect all the air cells, one by one, and spray the disinfectant on all sides, including all the connecting tubes and hoses. Let it sit for least 10 minutes. )
• If there is a base after you remove all the air cells, the base has to be sprayed down with the disinfectant, inside and outside. Let it sit for the required incubation time and wipe down with a cloth.
• Repeat the process with the tubing set: spray, incubate, and then wipe clean.
• The carrying bag should be turned inside out and completely wiped down using the  disinfectant solution. Allow it to thoroughly air  dry. Once the inside is dry, turn it back: wipe down the outside of the bag with disinfectant.
• Dry the mattress on a flat surface area after cleaning, away from exposure to the sun.
• Avoid long exposure to sunlight.

Handling and storage

• Lay the mattress out flat and upside down.
• Roll from the foot end towards the head end; the foot-end strap can then be stretched around the rolled mattress to prevent unrolling.
• Do not fold, crease or stack the mattress.

Maintenance

General

• Check the power cord and plug to see if there are abrasions or excessive wear.
• Check the mattress cover for signs of wear or damage. Ensure the mattress cover and tubes are connected together correctly.
• Plug in the pump unit and check the airflow from the hose connection port. The airflow should alternate between ports every halfcycle time.
• Check the air hoses to see if there are any kinks or breaks. For replacement, please contact your local agent or dealer.
• Make sure the mattress tube is well connected.
• Check the pump unit and make sure both power indicators are off when the switch is turned off.

Low pressure
Examine if there is any air leakage between the pump and the mattress connections or from the air mattress tubes:

• Check connectors between the air mattress and pump. If there is any disconnection, please reconnect it.
• Check the CPR Valves. Ensure their outlets are sealed.
• Check the air-connecting tubes. Ensure each single cell is not broken.
• Set the pressure at Max firm. Keep the tubes fully inflated and inspect for air leakage.
• Check if there is any air leakage from cells.
  Ensure no leakage occurs. If any leakage occurs, please contact your local agent or dealer.
