precautions detailed in this document should be observed.

Do not cover the pump unit with bedding or blankets.

Always protect your system from open ames, do not use in the presence of

cigarettes or smoking materials. Air circulation in the cushion will assist combustion if

the air cells are punctured allowing the released air to fan any burning.

Suffocation risk: The cover is not air permeable and may present a suffocation risk to

some patients. Ensure that the patient can use the product safely.

Do not expose the pump unit to liquids of any kind.

Do not use phenol based solutions when cleaning. Please note that certain patient

creams etc, that are petroleum based or similar may affect the re retardancy of the

product.

WARNINGWARNING

The HARVEST SEAT CUSHION is an alternating pressure relieving seat system used

in the prevention and treatment of pressure ulcers. This system is recommended

for use by a patient who would normally sit out of bed through the day but who

is still at risk from pressure sores. The maximum weight recommended for this

system is 25 stone / 159 kg.

The SEAT CUSHION uses the established principles of alternating therapy, this

offers the patient comfortable and relaxing support that can both prevent tissue

breakdown and help with healing.

The pump unit is both lightweight and compact; its features include a clearly visible

low-pressure warning indicator and a manual pressure / comfort control function.

The SEAT CUSHION is made up of alternating cells and is split up into 2 sections

consisting of odd cells e.g. 1,3,5 etc. and even cells e.g. 2,4,6 etc. These

two sections will alternate through a 10 minute cycle in which time both sets

of alternating air cells will have inated and deated sequentially. All air cells are

individually replaceable should any damage occur to them.

Quick release couplings between the pump unit and the seat enable easy patient

transfer arrangements. To deate the system simply disconnect the couplings

from the pump unit.

The cover is made of a multi-stretch, vapour permeable, waterproof PU fabric.

and/or vapour permeable cover upmost.

Connect the tubes leading from the seat cushion to the outlet ports on the pump.

Refer to the comfort control setting (on the front of the pump) and adjust the dial

according to the patient’s weight.

Connect the seat pump to the power supply and switch on the pump.

When the low pressure indicator has extinguished the patient may be placed on

the support surface.

Setting Procedure

It is important to follow the correct setting procedure to ensure the patient receives

adequate support while achieving maximum pressure relief and comfort. Failure to

follow this procedure could result in the patient being put at risk.

Set the correct pressure setting on the pump according to the patient weight

guide on the face of the pump.

If the pump unit has been used to power an air mattress before being

connected to a seat cushion, check the setting on the control panel for the

patient weight.

Sit the patient on the seat cushion when it is inated.

NOTE:

Ensure that the pressure setting is set to the correct setting when the patient is

returned to the bed if the pump has been used with a cushion. Failure to do so

could result in the patient being put at risk.

Ensure that the pump is giving out enough mmHg (millimetres of mercury) on

the maximum output by using either a sphygmomanometer or any mercury

/ digital pressure gauge. If not, adjust the comfort control parameters to

the correct range. If the pump is still not achieving the correct mmHg then

replace the motor or the relevant defective parts.

(Contact Harvest Healthcare for guidance on how to repair this device.)
