Patent attributes
A cushioning device having a first deep cell inflatable bladder, a first restraint structure, a pump and an attachment. The first deep cell inflatable bladder has a first side, a second side, an upper surface and a lower surface. The first restraint structure has a top surface and a bottom surface. The pump has (a) a maximum inflation mode that inflates the first deep cell inflatable bladder so the bladder's upper surface and the first restraint's top surface are in or approximately in the same plane and (b) a normal operating inflation mode that provides sufficient inflation to (A) prevent the first bladder's upper surface from contacting the first bladder's lower surface, (B) decrease (i) the formation of debuticus ulcers on a patient and (ii) the patient's tissue interface pressure, and (C) allow the restraint structure to inhibit and/or restrain the patient from rolling off the first deep cell inflatable bladder. The attachment attaches at least a portion of the first bladder's first side to the first restraint structure at a predetermined distance below the first restraint's top surface so (A) the first restraint during the normal operating mode inhibits and/or restrains the patient from rolling off the first deep cell inflatable bladder, and (B) the first restraint and first deep cell inflatable bladder provide lateral stability to allow the patient to get in and out of the cushioning device and facilitating patient transfers during the maximum inflate mode.
