Patent number: 6223369Abstract: Multiple varieties of patient support surfaces are presented with a common modular assembly primarily including a perimeter chassis and integrated upper support element. Perimeter bolsters provide relatively firmer support for gently prompting a patient towards the center of the bed, without obstructing regular entry and egress. The added stability facilitates safer transfers and better sitting at the edge of the bed. Pressure redistribution air cylinders (turned either longitudinally or laterally) are captured by shaped, slotted inner bolsters aid underside arches of an integral foam topper. All such features work collectively to cradle and surround the air cylinders. The resulting interlocking, integrated design provides flexible progressive support while maximizing structural integrity. Different arrangements of air cylinders and static or dynamic performance thereof, either non-powered or powered, permit different embodiments to be created using the same modular assembly approach.Type: GrantFiled: November 13, 1998Date of Patent: May 1, 2001Assignee: Span-America Medical Systems, Inc.Inventors: Edmund K.

Patent number: 5699570Abstract: A pressure relief valve vent line mattress system utilizes a self-adjusting approach with a single air source to obtain in combination a low air loss feature for beneficial cooling and drying of a patient's skin. A single air supply source outputs a predetermined positive flow of air into one or more patient air support bladders. An air distribution manifold received within a mattress body receives and disperses overflow pressure routed thereto from the patient air support bladders via an air passageway having a first pressure relief valve with an established set point. A second pressure relief valve is associated with a pump return line adjunct to the constant air flow pump. The net effect is to disperse overflow pressure from the mattress bladders (tending to keep such bladders at a constant pressure) while providing low air loss through the mattress for patient cooling and drying effects, all utilizing a single air flow source.Type: GrantFiled: June 14, 1996Date of Patent: December 23, 1997Assignee: Span-America Medical Systems, Inc.Inventors: John W.
