INTRODUCTION
Product Description
The Herida Wiltshire II is our second generation cushion used in the prevention and treatment of
pressure ulcers for patients in all categories of risk. It provides comfort and support by maintaining
a good level of blood flow around the body whilst seated.
This cushion contains a unique horizontal cell design that alternately inflate & deflate in a cyclical
pattern. This type of cushion is ideal for patients who spend a proportion of their day in long term
care, using a chair & is used in conjunction with a dynamic mattress system, under the required
level of supervision.
Application
For patients who are classed as medium to high risk of developing pressure ulcers.
Contraindications
Patients with severe spinal injuries / fractures should not be using this product.
This product forms part of a holistic care package and should only be used by trained personnel.
For training or further advice contact Herida Healthcare on Freephone [phone].
Working Principle
The dynamic cushion system consists of a manual air pump and an alternating air cushion. The air
cushion has three distinct airway chambers:
1. Group A Chambers –Air tubes 1,3 & 5.
2. Group B Chambers –Air tubes 2 & 4.
A and B chambers alternate inflating and deflating by using the pump connected. This air
alternating, cushion system enhances the blood circulation to treat and prevent pressure ulcers,
when part of a holistic care package. Initialisation can take up to 10 minutes to achieve.
Important Clinical Notes
The manual (or where applicable digital pump) pressure setting is for clinical application purposes
and of course patient comfort. When the pump is set to the indicative patient weight (refer to
clinical notes), it is important to ensure that sufficient clearance of the patients sacral area if lifted
off the chair and the product is fully functioning. A way to ensure that the patient is fully clear of the
cells during cycle and after initialisation, is to place a hand under the deflated cell and feel from the
side of the chair. If you have clearance the setting (other than comfort is suitable). If the patient is
not clear of the chairs surface, then please increase the pressure settling gently and repeat the
process after five to ten minutes.

Wiltshire II™
OPERATION
(NB: use hand to check ensure appropriate clearance when profiled as below. Add more pressure
on the pump if required in order to achieve this. NB: Weight setting is a guide only and cell
pressure must also be taken into consideration for individual patients). Clinical judgement must
always overrule user guidance.
Static Mode
Alternating Mode
When started, both chambers A & B are initially inflated to full inflation. Group A chambers deflate
for 5 minutes followed by both A & B inflating for 1.5 minutes. This is followed by Group B
chambers deflating for 5 minutes. This is one complete cycle.
When the pump is adjusted to the static mode, air chambers A & B are both
fully inflated until full inflation is achieved.
When started, both chambers A & B are initially inflated to full inflation.
Group A chambers deflate for 5 minutes followed by both A & B inflating
for 1.5 minutes. This is followed by Group B chambers deflating for 5
minutes. This is one complete cycle.

OPERATION
Installation
1. Remove all packaging & place the pump over the back of the chair on its hooks or on a flat
surface.
2. Ensure that there are no sharp or hard objects on the seat before unfolding the cushion &
laying out flat. The air inlet should be located at the rear of the seat.
3. Connect the pump to the socket & switch on.
4. Adjust the mode & pressure by the users condition & weight to suit.
5. In order for the alarm to activate, the system must be switched on & powered up for at least
5 minutes. This should give the internal battery on the PCB sufficient time to charge.
Safety Instructions
1. Ensure that there are no sharp objects, fire or abrasive materials in the vicinity. If the
cushion is damaged, remove the patient & transfer to an alternative mode of pressure relief.
2. If there is an issue with the pump, remove the patient & transfer to another mode of
pressure relief.
Pump Operation
Power: Power On / Off
Pressure Dial: Turn clockwise / anti-clockwise to increase / decrease the pressure setting as
required, depending on the weight & comfort of the patient. Each section represents 20kg
increments.
Static: All tubes will inflate up to full inflation. No alternating takes place & the dynamic cushion
system will remain in static mode until switched back to normal.
Pressure Monitor: The light is illuminated when pressure is normal & extinguished when pressure
is abnormal. The light will continuously flash during the alternating cycle change-over.

OPERATION
Air Leakage / Low Pressure Alarm
•After working for 50 minutes and the pressure is lower than 30mmHg, the pump will alarm
indicating an initialisation failure.
•During normal operation, when the pressure is lower than 30mmHg for 6 minutes, the pump
will alarm indicating possible air leakage from the cushion.
•Pushing the mute key will silence the pump alarm.
•If the alarm sounds consistently and all attempts to remedy have failed, seek engineer
assistance to rectify.
Power Off Alarm
The alarm will sound if power is lost to the pump.

MAINTENANCE - 12 Months or Upon Patient Return
At point of service the following aspects must be maintained to ensure that manufacturer’s
warranty remains intact. These can be done in a non-alphabetic way, if all areas are covered:
•Ensure the pump unit and cushion / cells are fully decontaminated prior to service and are
cleaned in accordance with the schedule provided.
•Electrical safety checks / Pat Test –To be conducted annually or time of service. Please
make sure the kettle lead and plug fuse is compliant at 3amp only.
•Filters must be changed at point of return / before patient handover / new client and at time
of service.
•Rear pump fuse must be inspected and replaced if faulty –0.5A only.
•Pump casing must be opened and vacuumed internally, if any dust or particles are evident.
Never use any water / fluid internally to clean.
•Pump must achieve pressure within 20% tolerances as per page 9 of this manual –via
calibrated sphygomometer and cell attachments. Kits available to purchase via
manufacturer. Ensure that a rapid inflator is used at time of service to ensure that service
and installation time is reduced to minutes.
•Pump low pressure function is evident at 6mmHG or lower for 15-20 minutes or more.
•Cells are to be fully inflated and tested for leakage. This should be done via a pressurised
system, soak test over at least 3 cycles or under weights to replicate patient in situ.
•The tubing and connectors that run down the side of the cushion, must be clear of kinks /
debris or must not be snapped in any way. These should be running freely with air
distribution to each cell and have no leakage or deterioration of surface.
•A functional “soak test”, ensuring that the tactile panel / pump and mattress operates fully in
synergy. This is done by attaching and inflating the mattress to full pressure and then
increasing / decreasing both weight and other panel / button functions.
•The pump, if stored for a period of time, may require attaching to the mains electric for at
least one hour prior to use. This is to ensure the battery is sufficiently charged, ensuring the
alarm function is fully functioning. Contact manufacture if a warranty item.
•Ensure the timer valve is rotating freely & a light application of grease should be applied if
required. The manufacturer recommended grease to use is Molykote 111 compound.
•Cushion cover and cells are to be inspected for puncture, tear, rip or excessive odour post
cleaning and replaced accordingly if defective.
•Calibration setting as required. See page 12 for further details.
Storage
Good ventilation will be required when storing the product & it should always be kept dry & away
from direct sunlight. Temperature should be maintained in the region of 22°C ± 3°C when in use.
Avoid repeat exposure to extreme temperatures.
