Span America Isch-Dish Seat Cushion, 18 X 18 X 3-1/2 Inch Foam, Black, Each - Model 221F

Since 1989, the Isch-Dish has been the most direct seating solution for those with, or at high risk for pressure ulcers at the ischium or coccyx. Unlike other products that merely equalize pressures across the seating surface, the unique, open pocket design of the Isch-Dish actually eliminates pressure at the ulcer site while ventilating heat and moisture. Caregiver selects the appropriate standard small, medium, or large pocket size based on a simple measurement of the ischial span. Documented as an important complement to any wound treatment, and for long term prevention. Promotes healthful, upright posture by controlling pelvic tilt. Reduces "sacral sitting" that can cause skin breakdown. Includes multi-tiered foam support core (see Tab 3 above) protected by Durafilm incontinence-proof coating, machine washable deluxe cover, removable Sling-Fill seat base, 2-year warranty. Sized Pocket: The unique, fit-to-the-user, U-shaped pocket provides pressure elimination at the ulcer site, while allowing full ventilation through the open back. Sizing the pocket correctly puts maximum pressure on the femurs, removing the danger of the “donut-effect” inherent in one-size-fits all, circular cut-outs. Pocket should fit close to the ischials without touching them. Femur Shelves: Flat shelves for the femurs allow even distribution of body weight across the length and width of the load-tolerant femurs. They also help to control internal or external rotation of the femurs. Multi-tiered core: The core of the Isch-Dish is made of layers of open-cell foam of varying densities and ILDs for support and longevity. Sling-Fill Base: Molded ABS plastic insert fills in the gap created by fabric slings. Creates a flat rigid foundation where needed. Included standard with every Isch-Dish. 1 Each / Each
