  • Patent number: 8366644
    Abstract: A reduced pressure treatment system includes a compressible chamber positionable beneath a foot of a user and being movable between an expanded position and a compressed position. The compressible chamber includes an inlet and an outlet. An inlet valve is in fluid communication with the inlet to prevent fluid within the compressible chamber from exiting the inlet, and an outlet valve is in fluid communication with the outlet to prevent fluid from entering the compressible chamber through the outlet. A biasing member is disposed within the compressible chamber to bias the compressible chamber toward the expanded position, and a manifold is positionable at a tissue site and in fluid communication with the inlet of the compressible chamber.
    Type: Grant

  • Patent number: 8021407
    Abstract: A patient cooling system comprises an inflatable patient mattress and a patient enclosure or tent supported by a framework of inflatable tubes drawing air off of the same air supply used to supply the mattress and to cool the tent. The framework of inflatable tubes is divided into left and right sections, which are further subdivided into lower body and upper body sections. An inflatable connector with a stem and protuberance is provided to secure the framework in a closed position. The patient-supporting mattress comprises a plurality of inflatable compartments extending transversely across the width of the mattress that can be alternately pressurized for pressure relief therapy. Radially collapsible, sleeved openings in the tent panel enable connection of conduits or patient care lines to the patient.

  • Patent number: 7507249
    Abstract: A patient cooling system comprises an inflatable patient mattress having an airflow system and integral manifold incorporated therein and a patient enclosure or tent coupled to the inflatable patient mattress and supported by a framework of inflatable tubes drawing air off of the same air supply used to supply the mattress and to thermally control the area in the tent. The framework of inflatable tubes is divided into left and right sections, which are further subdivided into lower body and upper body sections. An inflatable connector with a stem and protuberance is provided to secure the framework in a closed position. The patient-supporting mattress comprises a plurality of inflatable compartments extending transversely across the width of the mattress that can be alternately pressurized for pressure relief therapy. Air is recirculated from the area in the tent and the integral manifold through the airflow system and into a thermal control unit.

  • Patent number: 6945987
    Abstract: A patient cooling system comprises a patient enclosure or tent having a coaxial hose connection to a re-circulating air-cooling system. The hose comprises an inner tube to introduce air into the enclosure and an outer tube for the return air. The patient cooling system further comprises a patient-supporting mattress comprising a plurality of inflatable compartments extending transversely across the width of the mattress, which can also be supplied with cooled air. The compartments can be alternately pressurized for pressure relief therapy. Moreover, the compartments can be pressurized either with relatively low pressure cold air from the air cooling system, or with higher pressure air which acts to support the patient, but provides relatively less cooling effect. Radially collapsible, sleeved openings in the tent panel enable connection of conduits or patient care lines to the patient.
