Cushion Varilite Evolution Psv Valve With Incontinence Cover 16X16 
Cushion Varilite Evolution Psv Valve With Incontinence Cover 16X16  is ideal for wheelchair users with a high degree of tissue breakdown and symmetric positioning needs - It has superior pressure distribution, positioning stability and comfort. Therapists recommend the Evolution for individuals with motor and neurological dysfunction due to spinal-cord injury, stroke, multiple sclerosis, cerebral palsy, and traumatic brain injury. Therapists value the Evolution’s outstanding pressure distribution and postural support.
VARILITE Air-Foam Floatation makes the Evolution ultralight, without compromising pressure distribution and support.
Functional areas of the cushion are created by three types of foam: soft foam for the decubitus-sensitive area of the ITs; medium foam for the thigh trough, pelvic bucketing and pre-ischial bar; and firm foam for the perimeter and the medial thigh separator.
Bonding Evolution foam to coated fabric makes the cushion hold air. A valve releases air to immerse the user in the foam, the foam conforms to the user, and the user’s weight is distributed over the surface of the cushion.
Independent research has shown VARILITE air-foam floatation to be the #1 impact and vibration dampening technology (RESNA 2000).
- Four-way-stretch Fabric - Evolution foam is bonded to four-way-stretch knit fabric for maximum conformity during immersion. The fabric is puncture and water resistant.
- PSV - VARILITE’s PSV takes guesswork out of cushion adjustment and makes it automatic. Evolution PSV uses VARILITE’s revolutionary new Pressure Setting Valve (patent pending). The PSV works by sensing the amount of internal cushion pressure. As air is released, internal pressure decreases and the user is immersed in the cushion for effective pressure distribution. The PSV is marked with three pre-set positions, which provide the best range of immersion for most users. The therapist determines the PSV position that results in optimal pressure distribution for a client. (A therapist can mark a different position on the PSV if the user falls outside the pre-determined range.) Sitting on a fully inflated Evolution PSV, the client simply opens the PSV to the appropriate position. When the PSV senses that enough air has been released, it automatically shuts off the flow. The client closes the PSV. Adjustment is simple and consistent.
Ease of use improves user compliance. A therapist can select the Evolution PSV with confidence, knowing that a client or caregiver can adjust the Evolution PSV easily for optimal pressure distribution. The first time. Every time. Consistent.
Standard Valve for Adjusting Air Volume
Sitting on a fully inflated cushion, the user opens the valve and releases air, closing the valve when sitting on approximately 1/2 inch (13 mm) of air and foam.
