Patient undersheet for preventing bed sores

An undersheet apparatus for the prevention of bed sores in bedridden patients, said apparatus comprising:

• a base layer having a plurality of bubble-like supports each having a closed top and a bottom and a side, the bottoms of said bubble-like supports being connected together;
• a relatively porous upper layer having an air resistance of approximately 2%;
• and,
• adhesive means for attaching said upper layer to the top of said bubble-like support so that air channel circulation means are formed between said upper layer and said base layer for circulating air through said porous upper layer, a plurality of patient contact areas being formed substantially at the locations where said upper layer is ahdesively connected to the tops of said bubble-like supports,
• wherein said patient contact areas carry substantially all of the force exerted by the patient on the apparatus thereby producing a massaging-like stimulation of said patient.

An undersheet apparatus for the prevention of bed sores in bedridden patients, said apparatus comprising:

• a base layer having a plurality of bubble-like supports each having a closed top and a bottom and a side, the bottoms of said bubble-like supports being connected together;
• a highly porous upper layer which permits air to pass from said base layer through said upper layer;
• and,
• adhesive means for attaching said upper layer to the top of said bubble-like support so that air channel circulation means are formed between said upper layer and said base layer for circulating air through said porous upper layer, a plurality of patient contact areas being formed substantially at the locations where said upper layer is adhesively connected to the tops of said bubble-like supports,
• wherein said patient contact areas carry substantially all of the force exerted by the patient on the apparatus thereby producing a massaging-like stimulation of said patient.
