IMPORTANT CONSUMER INFORMATION

NOTICE: This manual contains important instructions that must be passed on to the user of this product. Please do not remove this manual before delivery to the end user.
SUPPLIER: This manual must be given to the user of this product.
USER: Before using this product, read this entire manual and save for future reference.
NOTE: Check all parts are free from shipping damage. In case of damage DO NOT use. Contact Sunrise Medical or your supplier for further instructions.
Sunrise Medical recommends that a clinician such as a doctor, therapist or rehab engineer experienced in seating and positioning be consulted to determine if a J3 Cushion is appropriate. Cushions should only be installed by:

an authorized Sunrise Medical supplier
a qualified healthcare professional who has undergone appropriate training by either Sunrise Medical or their approved supplier.

**** GENERAL WARNING

Do not install this equipment without first reading and understanding this manual. If you are unable to understand the Warnings, Cautions and Instructions, contact a qualified clinician or supplier – otherwise injury or damage may occur.
Hook and loop Velcro should not come into prolonged contact with moisture as this may degrade the adhesive and lead to a failure of the Velcro.

Introduction

The JAY J3 Cushion is designed for clinicians to use with clients who are at extremely high risk of skin breakdown. Designed for superior pressure distribution and stability, the J3 Cushion offers a high end cushion to meet a large rang of skin protection and positioning needs. The J3 Cushion has the benefit of skin protection in a comfortable and lowmaintenance design. The J3 incorporates a JAY Flow Fluid Pad, optional Fluid Inserts, optional PLA (pelvic loading area) reducer ring, foam base and one of two over materials.
The intended lifetime of this product is 5 years.
Maximum User Weight:

150 kg on Pelvic Loading Area ring sizes A and B 227 kg on Pelvic Loading Area size C
WARNING
Installing a cushion on a wheelchair may affect the centre of gravity of the wheelchair and may cause the wheelchair to tip backwards, potentially resulting in injury. Always assess the potential need for anti-tippers or amputee axle adapter brackets to be added to the wheelchair to help increase stability.
Prior to prolonged sitting, any cushion should be tried for a few hours at a time while a clinician inspects your skin to ensure that red pressure spots are not developing. You should regularly check for skin redness. The clinical indicator for tissue breakdown is skin redness. If your skin develops redness, discontinue the use of the cushion immediately and see your doctor or therapist.
The J3 cushion is designed to help reduce the incidence of pressure ulcers. However, no cushion can completely eliminate sitting pressure or prevent pressure ulcers. The J3 cushion is not a substitute for good skin care including
proper diet, cleanliness and regular pressure relieving.
WARNING
Do not leave the cushion outside overnight at temperatures below 40° F (5° C). Allow the cushion to warm to room temperature before using. Sitting on extremely cold or hot surfaces can cause skin damage.
Avoid sharp objects or exposure to excessive heat or open flame.
PROPER FLUID LEVEL: The amount of fluid contained in the insert is determined by the clinician during a seating evaluation. This should not be adjusted without a clinician directive as it can alter the pressure relieving properties and lead to injury or damage.
OBSTRUCTIONS: DO NOT place any obstructions between the user and the cushion because it will reduce product effectiveness.
CUSHION AND COVER ORIENTATION: Product must be used with the fluid insert facing up. If the cover is not used correctly or if the cover is the wrong size, it may reduce or eliminate the cushion’s benefits and could increase risk to the skin and soft tissue.

Cushion Adjustability
The size of the PLA (pelvic loading area) is adjustable.
Your clinician will determine if a PLA reducer is needed in your cushion at the time of your evaluation.
Fluid Adjustability
The J3 Cushion offers fluid volume adjustability to accommodate user’s needs through two models the “Factory Filled” or the “Field Variable Volume” model.
The determination of factory filled or field variable filled is made by your clinician during evaluation. The insert should only be changed at the direction of your clinician.
The field variable volume insert has the ability to adjust to the user’s need over time. Your supplier will be involved in the adjustment once it is determined to be needed for better clinical efficacy.
Adjusting the “Factory Filled” J3 Cushion
If at any time the volume needs to be modified, Sunrise Medical or its approved supplier can at no additional product cost modify the volume to meet current medical needs. This method of fluid adjustment prevents unqualified fluid adjustments. This allows the appropriate fluid amount to be controlled by the appropriate healthcare provider and prevents the fluid volume from being manipulated by a patient or caregiver that might place the patient at a higher risk for skin breakdown.
To modify the fluid volume of the Factory Filled Fluid Pad, simply contact Customer Services of JAY supplier, or Sunrise Medical.
Adjusting the “Field Variable Volume” J3 Cushion
The Field Variable Volume version of the J3 Cushion allows the appropriate healthcare provider to apply a specified amount of fluid at the time of prescription and to modify the amount of fluid if needs change through the use of discreet Fluid Supplement Pads. This method of adjustment is useful where there is no concern of unqualified fluid adjustments occurring after prescription.
WARNING
The Field Variable Volume Fluid Pad comes with two Fluid Supplement Pads as standard and has a blue urethane cover to differentiate it versus the standard grey urethane on the Factory Filled Fluid Pad. This colour difference identifies that the blue fluid pad comes underfilled in comparison to the grey Factory Filled pad, and has four Velcro attachment points to attach the standard Fluid Supplement pads for obliquities, and overfills. To determine how to use the Fluid Supplement pads, please reference the “Fitting a Pressure Distributing Cushion” section.
Fitting A Pressure Distributing Cushion
Using Fluid Supplements Pads.
Fluid Supplement pads are to be only used with the Field Variable Fluid pad. To determine if you have a Field Variable Fluid pad, unzip the cushion cover and look at the pad in the pelvic loading area. If the pad has a blue outer cover, it is a Field Variable Fluid pad and designed to work with Fluid Supplement pads.
Clinicians or therapists should use Fluid Supplement pads by attaching or removing to the Fluid pad Velcro attachment points located between the folds on the upper Fluid Pad surface to increase or decrease the amount of fluid needed.
Fitting The Cushion.
Select a cushion to match your hip width when in the seated position. The cushion length should extend to within 1” – 2” (2.5cm – 5cm) from the back of the knees.
Place the cushion to the back of the wheelchair with the material identification tags and fluid pad toward the rear.
When fitted correctly, your hips should be to the back of the chair. Your ischials (seat bones) should be centered on the JAY Fluid pad in the pelvic loading area of the cushion.
Proper footrest adjustment may enhance sitting comfort and help lower peak sitting pressures. Adjust the footrests so your legs rest firmly but comfortably on the cushion.
Use the cushion indexing notches located in the rear of the foam base to ensure proper alignment of the cushion to the backrest. This will ensure that the pelvic loading area and fluid insert are in the right position for the user.
Misalignment of the fluid insert and pelvic loading area could lead to injury and skin breakdown.
Avoid using the cushion on overly stretched seat upholstery. Stretched upholstery does not provide adequate support for the cushion and improper positioning may result. Replace stretched upholstery or purchase the JAY Adjustable Solid Seat.

Easy Maintenance & Cleaning

Monthly cleaning and regular maintenance may help extend the life of your cushion. During cleaning, component inspection is recommended.
Check the cover for tears and excessive wear and replace if ripped, torn or otherwise not fully functional. Inspect the fluid pad for punctures or any other abnormalities.
Check the foam base to ensure foam consistency. While checking the fluid pad if you ever feel the fluid is firmer in one area, simply knead the fluid back to its original consistency and/or call your supplier.

To Clean Cover

Remove the cover from the foam base and turn inside out.
Machine wash in warm water and drip or tumble dry on low heat.
No ironing required.

CAUTION

Do not dry clean covers or use industrial washers and dryers to clean cover.
Do not steam autoclave.
Do not bleach.
To refit cover after washing, reinstall the cover on the foam base. Ensure the back of the cover matches up to the back of the foam base.
If used in an institutional setting, write the resident’s name with a permanent marker on the content label of the covers. This will help to ensure the return of the covers after washing.
Use only JAY covers on JAY cushions. The cover is an important part of allowing the immersion into the fluid insert which redistributes the pressure. Changing the cover will alter this design and its efficacy.

To Clean Foam Base, Pla Reducer Ring And Positioning Components.

Remove the cover, fluid pad and PLA reducer ring (if applicable) from the foam base. Wipe lightly with a damp cloth. Do not use soap. Do not submerge in water. Wipe off with a clean cloth. Let it completely air- dry before reassembly.
Avoid submersion of the foam base in water.
Re-install the cover over foam base. Ensure the back of the cover matches up to the back of the foam base.

To clean fluid pad and fluid inserts (if applicable)
Remove the cover from the foam base. Remove fluid pad from its foam base and wipe with warm water and soap.
Rinse with a clean, damp cloth, then wipe dry with a clean cloth.
CAUTION

Never submerge the fluid pad in any liquid.
Avoid harsh cleaning or rough handling as this may lead to a degradation of the fluid insert and lead to a leakage.
If at any time the cover, Pelvic Loading Ring, foam base, fluid insert or any other component appears to be wearing or you notice a degradation in the texture, contact your supplier/Sunrise Medical for evaluation and further instructions.

Re-Assembling The JAY J3 Cushion After Cleaning

Follow cleaning and maintenance instructions as described in “Easy maintenance and cleaning” then re-assemble as follows.

WARNING

Insert the JAY Fluid pad on the foam base making sure that all Velcro® strip locations are aligned.
A mis-alignment or creation of an edge could cause an unwanted pressure point which could lead to injury.
Insert the foam base into the outer cover.
Ensure that the zipper is at the rear of the foam base (the part number tag should be to the rear of the foam base) where the pelvic loading area is located.

What Is Bottoming-Out?
Bottoming-out may occur on a J3 Cushion if you displace the fluid underneath your pelvic bones or buttocks, which would leave you sitting on the foam base. It sometimes occurs on very thin individuals, people using recliner wheelchairs, people who have lost weight or have other changes in body size or shape, people who slouch when sitting or a person using a PLA (pelvic loading area) inappropriately sized for their pelvis.
WARNING
When bottoming-out occurs, increased pressure is placed onto the ischial and coccyx increasing the risk of skin breakdown. Immediately discontinue use of the pad. See your health care professional.
How To Check For Bottoming-Out
To check for bottoming-out, sit on the cushion with the cover on and the zipper opened for at least two minutes.
Transfer up and off the cushion (or have someone help you transfer), trying not to disturb the fluid underneath you.
Fold the back portion of the cover forward over the front, exposing the fluid pad. Push down in the depressions on the pad where your ischial (seat bones) and coccyx (tailbone) were. You should have to push through at least 1/2” (1.3 cm) of fluid before you feel the firm cushion base below.
1/2” (1.3 cm) is approximately this deep.
WARNING
If the cushion is properly positioned, the footrests are properly adjusted and there is not at least the minimum 1/2” (1.3 cm) of fluid, the cushion is bottoming-out and should not be used.
If you are bottoming-out, discontinue use of the cushion and see your clinician. Usually bottoming-out is easily solved by ordering additional fluid in the form of an Overfill on the Factory Filled model. On the Field Variable version, you can use the Fluid Supplement pads to add additional fluid. Call your local supplier to see if this is appropriate for you.
When To Check
Check your cushion and fluid pad every month when you clean it.
