  • Patent number: 10143609
    Abstract: A medical air mattress has a mattress body and an upper bedspread. The mattress body is formed by multiple air cells including independent air cells parallelly arranged as an air cell row. The upper bedspread covers the mattress body. The independent air cells are connected to the independent deflating unit to be deflated independently. When the patient needs to use the bedpan, the independent air cells are deflated to form a recess for receiving the bedpan so that the patient needs not to move.

  • Patent number: 10045632
    Abstract: A traveling wave air mattress apparatus includes an air mattress comprised of an array of laterally disposed, longitudinally spaced air bladder cells that are individually inflatable to quiescent pressure levels which provide comfortable support for a human body, and an air pressure-pulse generator controlled by a wave sequence generator for periodically introducing into sequences of the air bladder cells timed sequences of air pressure pulses which vary pressures in the cells from quiescent pressures, the air pressure variations resulting in leading and lagging soliton-like traveling waves of body support force variation which travel longitudinally over the surfaces of the pulsed air bladder cells, thus inhibiting formation of bedsores. The wave patterns may optionally simulate water waves and/or rocking motions of a boat to produce relaxing effects.

  • Patent number: 8914928
    Abstract: An alternating pressure pad (1) comprises inflatable cells (9,10) supplied with air by supply lines (7, 8) from a compressor (2) via supply line (3). A pressure controller controls the output of the compressor. Also connected to supply line (3) is an angle detection valve (40) restricting flow of air to atmosphere with increase in its angular position and a pressure transducer (17). Any increase in pressure due to an increase in angle of the detection valve (19) results in back pressure in the detection line. The pressure controller (2) uses the pressure transducer (17) to detect this change in pressure and then acts to adjust compressor output to the cells (9, 10) accordingly. The angle detection valve (40) is positioned under the head section of the pad to move with the head rest section.

  • Patent number: 8910334
    Abstract: A patient support includes a layer of fluid pressurized bladders, the bladders each having a chamber and an upwardly facing surface for facing and supporting a patient, and a cover over the layer of fluid pressurized bladders. Respective bladders in at least a group of the bladders each have a resilient body in its respective chamber to reform the shape of the respective bladder when a compression load on the respective bladder is removed wherein the pressure in the respective bladders is generally maintained without a powered supply of air. The cover has an upwardly facing patient surface and a bladder layer facing surface, with the patient surface for forming a patient support surface on the support, and the bladder layer facing surface for lying on the upwardly facing surfaces of the bladders.

    Abstract: Method and devices for the prevention and treatment of pressure ulcers are described in which a portable support assembly may be worn by a bed-stricken individual around particular regions of the body where pressure ulcers tend to form. The portable support assembly may generally include one or more individual fluid filled pods which are enclosed entirely within an inner fluid pad localized along a central portion. Both the one or more pods and inner fluid pad are then enclosed entirely by another layer of fluid within an outer fluid pad which extends over the entire assembly. Each of the fluid layers may be secured to an outer shell which is relatively stiffer than the fluid layers and may restrict or limit the expansion or movement of the fluid pods and/or fluid pads.
