Notes

General The Transair Overlay is an alternating pressure relief overlay system for High Risk patients.* The complete system comprises of a mattress with two sets of air cells, a two way hose set attached to the mattress, a microprocessor controlled pump unit and a 5 metre power lead with moulded plugs fitted at each end. Installing the System Unroll the Transair Overlay mattress onto the existing bed mattress with the hose exit at the right hand foot end of the bed. Secure the Overlay mattress with the end flaps and press fasteners attached. Place the pump unit at the foot end of the bed, preferably hung by the built in hooks onto the foot board or rail. The hooks are released from their carrying position by depressing them into the case and turning outwards. Connect the hose set between the pump and mattress. The hose connectors are opposites and may be connected one way round only. Connect the pump mains lead to a suitable power supply and switch on. Switch on the pump unit. The switch will be illuminated green. The system should now be left to pressurise.

Controls The control panel has tactile push buttons to adjust operating pressure to suit the comfort requirements of the patient and to control the audible alarm. The left hand button adjusts pressure, for comfort purposes, in three steps. The level selected is indicated on the front panel by three LEDs marked ‘Soft’, ‘Med’ and ‘Firm’.

After switching on the system will enter it’s Pressurising Mode. The control panel will be in-operative, the alarm mute indicator will be lit and the alarm will not function. The ‘Soft’ LED indicator will be slowly flashing. Both banks of cells will commence to inflate until the minimum working pressure is achieved (nominally 28 mmHg) when the system will enter:Normal Mode. Three bleeps will indicate this change. The system will normally reach working pressure within twenty minutes. Failure to inflate to pressure will be detected and the alarm will emit rapid beeps, indicating a system failure. When Normal Mode is entered the system will light the ‘Mid’ LED indicator. The control panel will become operational, the alarm will be functional and the alarm mute indicator will be extinguished. By default the system will select the middle level of comfort. The comfort control may now be adjusted to suit the needs of the patient. Each press of the button will increment the pressure by one step. When the firm level has been reached the next press will revert the pressure to minimum. If the Care Plan requires the patient to be sitting almost totally upright for long periods then the firm level should be selected

Alarm Mode. The alarm facility is functional in all modes except Pressurising Mode. Should the pressure in the system fall below effective levels continuously for longer than two minutes then Alarm Mode will be triggered. If the pressure rises to effective levels during the two minute delay period then the delay will be reset to commence a further two minutes delay.

Warranty The Transair Overlay system is manufactured from quality materials engineered to operate effectively and give many years of good service. Karomed provide a warranty for the product of two years. Under the terms of its warranty, Karomed agrees to cover its product against component failure for a period of two years. Upon receipt of the product, at the Karomed Service Centre, Karomed will correct the fault and ensure that the system is running effectively thereafter. Parts and Labour will be covered by Karomed. If the product fails because: i) it has not been used in accordance with the manufacturer’s instructions. ii) has been damaged by the customer or his/her staff iii) all reasonable care has not been taken to maintain proper accommodation and facilities for the equipment.

The alarm indicator will flash and the audible alarm, unless previously muted, will sound intermittently. The audible alarm may be muted by pressing the ‘ALARM MUTE’ button. Repressing the button will cause the alarm to be audible again. The system will now attempt to counter pressure loss by inflating both banks of cells. The purpose of this is to prevent a bank of cells from exhausting to relief in normal cycle, whilst the other bank may be deflated due to leakage. Should pressure be restored to effective levels then the Alarm Mode will be cancelled and the system will return to Normal Mode.

then Karomed reserves the right to raise an Invoice for the cost of repair, parts and labour at rates published from time to time.

In the event of the need to return the product under warranty, or otherwise, prior arrangement should be made by calling the National Helpline Number. Contamination procedures detailed in Cleaning and Infection Control Procedures must be adhered to when returning any product.

Note: In Alarm Mode the pressure is set by the system to maximum, therefore the comfort control button is inoperative in this mode

Service and Maintenance Apart from regular cleaning as detailed above the Transair system is designed to be virtually maintenance free. The hose set and connections from the mattress to the pump unit should be periodically checked for damage or excessive wear. The mains lead should be carefully checked for wear or exposure of the inner conductors at the entry to the plugs. Damaged leads should not be used. Refer to a competent electrician for advice or repair.

Power Fail In the event of power loss the alarm will sound continuously until the ‘ALARM MUTE’ button is pressed. Note: Whenever power is interrupted, and subsequently restored, the system will reset into Pressurising Mode. Transport Mode If it is necessary to move the bed with the pump disconnected it is possible to retain the air in the mattress by simply joining together the two end connectors of the mattress hose set

The pump unit may be powered up in the Normal Mode to test alarm functions etc, without waiting for the mattress to be pressurised. This is achieved by switching on the pump unit with the alarm mute button held pressed. Three ‘bleeps’ will be heard to indentify that Normal Mode has been entered. With no mattress connected the alarm should sound within three minutes. There is no user adjustment to the set levels and on no account should attempts be made to make any adjustment to the control circuit board. Karomed recommends that the internal filters of the pump unit are checked and cleaned or replaced every twelve months. This involves the dismantleling of the pump unit and should therefore only be carried out by competent qualified staff. The Karomed Service Centre offers full service facilities and may be contacted through the National Helpline.

Troubleshooting Guide

Cleaning and Infection Control Procedures

Karomed operates a 24 hour support service for all of it's products but experience has shown that many 'faults' can be cured without the need to call for assistance. Please check the following before calling for an engineer

Always use universal precautions, especially where the product is known or suspected of being infected. Refer to your Infection Control Manual or Department for advice.

System appears to be 'dead' If the mains switch is not illuminated then mains power has been lost. • Check that the unit is plugged in and switched on. • Check/ replace fuses in mains plug and/or mains inlet System will not pressurise or pressure is lost

• Check hose set is correctly fitted into the pump unit. • Check that the bed frame does not foul the hose set. • Check for mattress leaks, especially at 'tee-piece' connections into the cells. • Check for punctures in mattress cells. Note: The pump unit will not allow you to use any functions until the system has reached operating pressure.

For every day cleaning the mattress cover may be wiped with neutral detergent and warm water. For heavier soiling the mattress cover may be removed and machine washed (not tunnel washed) at 70 degrees C. and tumble dried. Protect against iodine based products which may stain the cover. If the internal cells become stained with body fluids, they may be sponged with a mild detergent and dried thoroughly. This depends on the type and extent of soiling. For extensive soiling with potentially infected body fluids, 0.1 percent Hypochlorite solution may be used under careful control. This applies to both the cover and the cells. The mattress base and sides may be washed over with either mild detergent or 0.1 percent Hypochlorite solution as above. The pump unit, tubing and mains lead may be wiped over with a mild detergent after ensuring that the mains supply is disconnected. Do not over wet the pump as fluid may then enter the case. Decontamination The Karomed Service Centre operates a Cleaning and Decontamination Service for the users of Transair systems. Further details may be obtained from the Karomed National Helpline Number. In the event of return to the Centre a completed HSG (93)26 form should be provided and all the components (mattress, tubing and pump) placed in yellow bags and sealed. The contamination status should be clearly indicated and provision made for staff protection (Universal Precautions) during disassembly and/or transport.
