  • Patent number: 10130538
    Abstract: A pneumatic mattress having a plurality of pneumatic cells so connected that sets of them can be selectively and cyclically pressurized and exhausted in sequence to support a user, or permanently inflated. The mattress also including an air flow manifold within a cover around the cells for providing air flow to spaces between some of the pneumatic cells beneath of the cover. The cells are provided transversely of the mattress with longitudinal edge cells, and the air flow manifold is provided inwards of the longitudinal cells across the ends of the transverse cells. The cover is semi-permeable to allow moisture from the patient to be carried away by the air flow. Between the cells and the cover, a replaceable open weave or gauze layer of non-woven material is provided, allowing air flow from one inter-cell space to the next with the cover held from the cells by the gauze layer.

  • Publication number: 20120017376
    Abstract: A body support assembly comprising a first layer (e.g., a visco-elastic foam) having a lower surface, and a second layer supporting the first layer and having an upper surface. One of the upper and lower surfaces is defined by a non-planar surface to define a plurality of passages. A fan is positioned to move air through the passages. Preferably, the non-planar surface comprises a plurality of protrusions (e.g., a convoluted surface). The body support can further comprise a sensor that detects a parameter and produces a signal, and a controller coupled to the sensor and programmed to control the fan. Multiple fans and sensors can be provided, and the controller can control the fans to provide different air flows through different locations of the body support assembly. A user interface can be coupled to the controller to allow selection of a desired parameter of the body support assembly.

  • Publication number: 20110296611
    Abstract: A climate controlled seat, bed or other assembly configured to receive a person includes a blower and two or more thermoelectric devices or other conditioning fluid modules. According to one embodiment of an operational scheme, a control system for the seat or bed is configured to continuously discharge air from the blower through the thermoelectric devices. In one arrangement, the thermoelectric devices are sequenced between an activated and a deactivated position. Consequently, the desired cooling and/or cooling effect can be maintained while reducing energy consumption of the climate control system.

  • Publication number: 20110247143
    Abstract: A person-support surface comprises a non powered mattress and a coverlet positionable on the non powered mattress. The coverlet includes an entry positioned at a first end of the coverlet, an exit positioned at a second end of the coverlet opposite the entry, an upper air impermeable layer, and a lower air impermeable layer coupled to the upper air impermeable layer to form an air flow path along the coverlet between the entry and the exit. The upper air impermeable layer is a vapor permeable and the lower air impermeable layer is a vapor permeable.

  • Patent number: 8002940
    Abstract: An inflatable convective thermal blanket is designed to have at least one section on its top surface that has securely mounted thereon at least one fluid absorbent mechanism for absorbing fluids from a subject that is placed onto the blanket, or from fluids fallen onto the blanket from other sources. The one section is configured onto the blanket in such a way that it forms a well for collecting the fluids. The fluid absorbent mechanism, which may be in the form of a pad, would absorb the collected fluid to thereby minimize evaporative and cooling effects on the subject. Instead of mounting it on top of the blanket, the fluid absorbent pad may be mounted to the underside of the blanket, with appropriate holes and/or openings provided at the fluid collecting section, so that the collected fluids are drained onto the fluid absorbent pad.

  • Patent number: 7945979
    Abstract: A mattress with airflow-circulating function has a main body and a ventilator. The main body has a crisscross groove formed in the main body. The ventilator is detachably connected with the main body and has a hollow joint, four extending tubes and a curved tube. The joint has five openings. The extending tubes are respectively and securely connected to four of the openings of the joint to form a cross and are mounted in the groove. Each extending tube has multiple apertures formed in the extending tube. The curved tube is securely connected to the other one of the openings of the joint and is mounted through the main body. Accordingly, air can be pumped into the joint and is ejected out from the apertures toward the part of the human body. Therefore, the circulating airflow can massage the part of the human body, relieve the pressure and facilitate blood circulation.

  • Publication number: 20110010850
    Abstract: A non-inflatable resting device used for heating and cooling is provided with a plurality of interconnected channels located close to an external surface of the resting device. Each channel substantially occupies the space between two support beams and the interior of said external surface. The comfort level of the resting devices is considerably increased while maintaining adequate structural integrity of the channels when the support beams are constructed with a cushion material having layers of different hardness levels. The top layer is a cushion material with high initial softness ratio. The arrangement of the channels and beams allows a non-pressurized conditioned fluid to flow underneath of the external surface providing a resting device with a heating and cooling system with unmatched energy efficiency. The high energy efficiency of the proposed resting device is due to the elimination of the compressor motor and the thick cushion layer used on the top surface as required by the competition.
