Installation and Set-Up

7.1 Setting up mattress
For the comfort and safety of the patient do not put them onto the mattress overlay until you are sure that the mattress overlay is properly secured and the system indicates that it is fully inflated. The mattress overlay is designed to be placed on an existing base mattress which may be in use on a bed or can also be used on a standard divan bed.
Place the mattress overlay on top of the base mattress, ensuring that the air pipe connector is situated on the bottom left hand side of the bed foot end (as viewed from the foot of the bed). Secure the mattress overlay to the base mattress by utilising the elastic security straps fitted to the base cover of the mattress overlay. These elastic straps should be secured around the base mattress.

Caution : Do not use the Tamora II mattress overlay directly on the bed frame.
Caution : Ensure when fixing the mattress overlay to the bed the security straps are only fitted to the moving parts of the mattress platform. Straps secured to the fixed
parts of the mattress platform will damage the bed/mattress when operated.

7.2 Setting up power unit
Whilst holding the power unit, unfold the hanging hooks on the rear of the power unit and hang it from the beds footboard. If required the power unit can be placed on the floor at the foot of the bed.

Caution : Ensure that the power cable is routed in such a manner so that it cannot be twisted, trapped, crushed or stressed.

7.3 Cable management system

Cable management fixings are located on each side of the mattress overlay underneath the flap of the cover. The mains power cable should be secured through the cable management fixing as follows:

• Locate each cable management fixing.
• If necessary, open the press studs.
• Run the mains power cable along the side of the mattress overlay securing each fixing loop around the cable using the press studs.

7.4 Connecting mattress to the power unit

Remove the cover of the air pipe connector and connect the air pipe connector to the power unit and then ensure that the air tubes are free from any kind of obstruction, and are not kinked.
Plug the power cable into a suitable electrical socket and switch ‘ON’ using mains power switch found at the side of the power unit. All indicators on control panel will light up.
The power unit will start Inflation (inflation mode) and the Normal Pressure indicator will flash. Turn the comfort control to the maximum. Once the mattress overlay is fully inflated, you can then set to the appropriate setting suitable for the patient.

Caution : The power unit must only be connected to the mattress overlay recommended by the manufacturer. Do not use it for any other purpose.
Note : Ensure that the CPR tag is replaced in position over the CPR plugs.

Control Panel Operation Guide

The Control Panel of the power unit is used to make adjustments to the mattress overlay and also indicates fault conditions/service requirements. These are either visual (indicator lights) or audible.

8.1 Comfort level

The comfort level adjustment dial allows carers to adjust pressures within a safe pre-set range to provide patients with enhanced comfort or support whilst maintaining a very good level of protection and therapy. Qualified clinical advice must always be taken before adjusting mattress overlay pressures.
When the dial is turned towards Firm, the output pressure will increase to provide a higher pressure output and thus increased support.
When the dial is turned towards Soft, the output pressure will be decreased to provide a lower pressure output and thus increased comfort.
To check if the pressure is adequately supporting the patient, slide one hand between the mattress overlay and base mattress to feel under the patient’s bottom. You should be able to slide the hand inbetween and an acceptable range is approximately 25 to 40 mm (1” to 1-1/2”) to ensure the patient Is not bottoming out.

8.2 Control panel lockout

If the control panel is not used for a period of 30 seconds it will lock out and inhibit the use of the functions. Additionally, if you wish to lock out the control panel press the Lock Out button and all functions will be locked. This is to prevent the system being altered accidently.
In order to unlock the control panel, simply press and hold the Lock Out button for 3 seconds, the control panel will now be active for use.

8.3 Function mode switch
8.3.1 Alternate

Alternating mode is the default mode for the system. Within this mode the mattress will operate in an alternating 1-in-2 cell cycle. The alternating cycle will continue at the selected cycle time until another mode is selected.

8.3.2 Static

Pressing the Mode button until the Static indicator illuminates puts the system into Static mode.
Within this mode the mattress will maintain a selected constant pressure. After 30 minutes the system will automatically revert back to Alternating mode.

8.4 Alternate cycle time selection

The alternating cycle times can be selected to provide an individualised care program for each patient.
Within Alternating mode the cycle time can be selected by pressing the Mode button.
Selections can be made from 10-20 minutes at 5 minute intervals. The cycle time selection will be indicated by the relevant indicator light being illuminated.

8.5 Alarm mute

The Alarm Mute button temporarily resets the audible Low Pressure/Power Failure/Service alarms. Should the situation not be resolved and the fault condition continues the alarm will resume notifying carer.

CPR Mode

CPR (Cardio Pulmonary Resuscitation) can be performed using the red CPR valve which is situated at the head end on the left hand side of the mattress.
For rapid deflation gently pull and rotate the dial of the CPR valve to ‘click’ into the OPEN position. At the same time, disconnect the air pipe connector from the power unit to speed up the air release.
If re-inflating the mattress, ensure the dial of the CPR attachment is rotated until it ‘clicks’ into the CLOSED position.

Transport Mode

If the patient is being moved on the mattress overlay, or there is a power cut, general pressure can be maintained in the system for an adequate period of time whilst disconnected from the mains.
Simply disconnect air pipe connector and place the connector cover over it. The air pressures in the mattress overlay will now equalise, but maintain a degree of comfort. This will maintain the cells in their present state for up to 24 hours.
It is important to restore the Tamora II dynamic overlay mattress as quickly as possible by reconnecting the supply tubes to the power unit.

Alarms & Fault Findings

The Tamora II is equipped with audible and visual alarm indicators. These alert the user to the status of the available mains supply and any mattress defect.
11.1 Low pressure alarm
Upon detection of low pressure, an audible alarm will be heard and the Low Pressure indicator will illuminate. The audible alarm may be cancelled by pressing the Alarm Mute button. The Low Pressure indicator will continuously illuminate until the low pressure fault condition is resolved.
This condition could be caused, for example, by incorrect fitting of the air pipe connector, opening of the CPR valve or a leak in the mattress due to a cut or puncture.

11.2 Power failure alarm
If at any time the mains power should be removed from the power unit or the power cable is unplugged without turning the power unit OFF, an audible alarm will be heard  and the Power Failure indicator will illuminate. The audible alarm may be cancelled by pressing the Alarm Mute button.

Note : When the power unit has not been used for more than 3 days, it might require 30 minutes operating time (or more) for the Alarm to function correctly.

11.3 Service (alternating failure alarm)
Should your system develop a fault condition whilst in use, an audible alarm will be heard and the Service indicator will illuminate. The audible alarm may be cancelled by pressing the Alarm Mute button. Should the situation not be resolved and the fault condition continues the alarm will resume.
Please contact Ultimate Healthcare or your local service provider.
