摘要:
The present invention provides a device and method for preventing or curing pressure ulcers or chronic wounds. A multilayer dressing comprises a soft silicone jell layer of a suitable thickness which is placed in the multilayer dressing, above an absorbent layer. The matrix of the silicone jell layer is populated with a plurality of silicone beads of suitable size. The beads are connected to each other, and to the silicone jell layer. Breathing of wound and substantial supply of oxygen to the wound is duly insured for all layers of the multiple layer dressing. The beads play a pivotal role in promoting the effectiveness and performance of the multilayer dressing by acting as the plurality of effective cushions, as they absorb and uniformly redistribute a patient's body weight across the entire applied dressing area. The low adhering adhesive coating of about 5 mm in width is applied to the peripheral edges of all the layers. Unlike the multilayer dressing already available in the market, skipping the application of low adhering adhesive coatings on the entire top and bottom surfaces of the layers helps in promoting overall breathability and consequently, the efficiency of the multilayer dressing of the present invention.
