Dynamic Cushion and Mattress System

The TRINOVA Dynamic Cushion and Mattress System is suitable for patients showing any of the following characteristics: •

Assessed to be up to very high risk of pressure sore development.

•

Require therapy to promote pressure sore healing.

•

May have limited mobility but can be repositioned if necessary.

•

Can sit out of bed for more than a few minutes.

The TRINOVA System reduces skin surface pressure at frequent intervals. This encourages the blood flow necessary to maintain healthy tissue, thereby giving therapy and prevention from pressure sores in vulnerable patients. The mattress system offers a Step Down mode which is a static, lower pressure mode to assist in the assessment of patients whose condition continues to improve. The system also offers comfort for the patient, firm side supports to facilitate bed/chair transfers and ease of use for the carer. Patients who are immobile and/or cannot be repositioned when necessary, are therefore at greater risk and can be nursed on the CAIRWAVE Therapy System. NOTE:

Optimal performance is, in part, dependent on attaining a good seated position (chair height and posture), see Section I.

FAST INFLATE MODE (Fast Mattress Inflation) When switched ON with the air connector in Normal position and the mattress fully deflated, the system will automatically go into Fast Inflation Mode to ensure the mattress inflates quickly, allowing the system to be used in the shortest possible time (max 30 min). While the system is in Fast Inflate Mode, the amber Static Mode indicator light will continually flash. If the system is switched ON with a partially inflated mattress, Fast Inflation will continue for a shorter period before reverting to Normal Mode. NORMAL MODE (Normal System Operation) When the Fast Inflation Mode is completed, the system will automatically go into Normal Mode with the mattress cells inflating and deflating (cycling) and the green Normal Mode indicator light constantly illuminated. STATIC MODE (Mattress not Cycling) WARNING:

The patient will not receive the full benefits of the system while it is in Static Mode, therefore the system should be returned to Normal Mode as soon as possible.

Some nursing procedures may require a static, fully inflated mattress. This is achieved by pressing the Normal/Static pushbutton to initiate Static Mode. A single beep will sound to indicate Static Mode is selected. Static Mode enables the PMU to inflate all cells fully and to maintain full inflation. When Static Mode is selected, the amber Static Mode indicator light will illuminate. Static Mode runs for 30 minutes, after which it reverts to Normal Mode, unless an extension is made. An alarm sounds after 25 minutes to warn of a return to Normal Mode. To extend Static Mode for a further 30 minutes within the last 5 minutes, press the Normal/Static Mode pushbutton twice. If Static Mode is re-selected within the last 5 minutes, or up to 15 minutes after reversion to Normal Mode, the system assumes an extension has been made and will not allow a further extension. Only one extension is allowed and Static Mode cannot be selected for 30 minutes after the extension is finished. NOTE:

You can toggle between Normal and Static Modes by pressing the Normal/Static Mode pushbutton, unless it is within 30 minutes of a Static Mode extension.

STEP DOWN MODE (Mattress not Cycling) Enables a patient assessment to be made of the requirement for continued use of the system. Step Down Mode can only be selected when in Normal or Static Modes. To start or stop Step Down Mode, press and hold the Alarm Reset and Normal/Static pushbuttons at the same time until a beep is heard. When Step Down Mode is selected, the mattress becomes static and the pressure automatically reduces. Step Down Mode has High and Low pressure settings. To toggle between the two settings press and hold the Normal/Static Mode pushbutton once each time until a beep is heard. The pressure selected can be seen by the Static Mode LED flashing in groups of two (low pressure) and three (high pressure) flashes.

11

To ensure a regular check is made of the patient and the nursing staff are aware of the system being in Step Down Mode. An alarm will sound after 2 hours in groups of 2 or 3 beeps depending on pressure selected and will continue to sound at regular intervals. The alarm can be cancelled by pressing the Alarm Reset pushbutton but will sound again after 2 hours. NOTE:

While in Step Down Mode, the patient only receives pressure care equivalent to a quality pressure redistributing foam mattress.

CARDIO PULMONARY RESUSCITATION (CPR) In the event of cardiac arrest, turn the air connector to the CPR position. The mattress will immediately begin to deflate.

♥ CPR CPR

FOR RAPID DEFLATION TURN CONNECTOR FULLY IN DIRECTION OF ARROW (DO NOT DISCONNECT)

When the connector is turned to the CPR position the alarm will sound for a few seconds and the red heart will flash. The flashing red heart will cancel when CPR is no longer selected or if the Patient Management Unit (PMU) is switched off. If CPR is required while the bed is being moved and the system is in Transport Mode, ensure the connector is disconnected from the PMU, turn the air connector to the deflate position. This will allow the mattress to deflate to enable CPR to be carried out.

CUSHION CONNECTED When the cushion is connected in place of the mattress, the cushion indicating light will illuminate and all other lights will extinguish. ALARM FUNCTIONS CHECK AIR CONNECTOR INDICATOR LIGHT The amber Check Air Connector indicator light will flash when the air connector is not correctly in place or is in the Transport Mode with the PMU turned on. SERVICE REQUIRED INDICATOR The amber Service Required indicator light will flash after 10,000 hours of use, when a routine system service is recommended - contact the Service Organisation. The system will continue to function normally whilst in this state. SYSTEM ALARM The red System Alarm indicator light will flash and the audible alarm will sound if there is a system fault. There will only be an audible alarm: 1.

Every 2 hours when in Step down Mode.

2.

Within the last 5 minutes of Static Mode.

3.

If the air connector is disconnected.

4.

For 10 seconds when CPR is selected.

The System Alarm indicator light can only be reset by turning off the PMU. ALARM RESET BUTTON Resets the audible alarm when pressed. All alarms other than the power down alarm will return after 30 minutes if no corrective action is taken.

13

TRANSPORT MODE (Mattress not Cycling) WARNING: NOTE:

The patient will not receive the full benefits of the system while it is in Transport Mode. Therefore the system should be returned to Normal Mode as soon as possible.

Prior to disconnecting the mattress for transport, it is recommended that Step Down Mode is selected to provide support for the patient during transport (for Step Down Mode, see page 11).

When moving the bed with the mattress still inflated, or in the case of power failure, turn the air connector to the Transport position and disconnect. This will maintain the cells in their present state for approximately 24 hours. AIR CONNECTOR RECEPTACLE

SECTION D – ALARMS AND FAULT FINDING ALARM FUNCTION The System has audible and visual indicators to alert the user to the system status. In normal conditions with mains power available, the Patient Management Unit (PMU) turned on and the mattress fully inflated and cycling, the Normal Mode indicator light on the PMU front panel will be green and the mains light on the switch socket illuminated. If at any time the mains power should be removed from the PMU, an audible alarm will be heard. The audible alarm may be cancelled by pressing the Alarm Reset Pushbutton on the PMU. Should your system develop a fault whilst in use, the System Alarm indicator light will turn red and an audible alarm will be heard. This alarm may be cancelled by switching OFF the PMU and then pressing the Alarm Reset Pushbutton. NOTE:

The red fault light may flash in a series of two, three, four, five or six flashes. This is to assist the supplier when contacted about the fault.
