ABSTRACT:
The therapeutic mattress comprises an elastic but hard base layer of foam material. Over this base layer is applied a frame composed of a hard part and a soft part. On its upper side the mattress is bounded by a soft cover layer. Between or inside the aforementioned parts is disposed a core comprising essentially two groups of three air-cushions each and an insert. Each of the two air-cushion groups has its own connection to a pumping station equipped with a programmable control device. Using this control device it is possible to set up the most varied programs and cycles for moving a patient and positioning him, or repositioning him, as often as needed. In this way, decubitus ulcers may be prevented from developing, but in addition, conditions may be created to enable ulcers already developed to be healed.
