  • Patent number: 9439803
    Abstract: A patient warming device with patient access for maintaining normothermia and/or treating hypothermia is provided. The device includes a first compliant layer and a second compliant layer sealed together around an outer border to contain a liquid between the two layers and to form a wrap that surrounds and conforms to a body portion of a patient. A plurality of flaps extends from opposite sides of a generally longitudinal central portion of the wrap, such that one or more flaps from the opposite sides fasten to each other to surround the body portion. The flaps are openable during functional use to provide access to an underlying patient body surface. A continuous fluid flow path extends between the first compliant layer and the second compliant layer between a fluid inlet and a fluid outlet to carry liquid and deliver heat through the wrap.

  • Patent number: 9433527
    Abstract: A compressive patient warming device is provided. The device includes an elastic inner layer that conforms snugly to a shape of an appendage of a patient so that the inner layer wraps around and substantially contacts most of an underlying surface area of the appendage. An outer layer is attached to and covers the inner layer to form a space that holds a heat transfer medium between the inner layer and the outer layer while the inner layer is wrapped around the appendage. The outer layer may be a rigid layer, and a predetermined compressive load may be applied to the outer layer to encourage blood flow in the appendage. A source of heat may be applied to the device to maintain normothermia and/or treat hypothermia.

  • Publication number: 20160105977
    Abstract: The unit comprises an assembly for clasping-escaping and a receptacle-terminal assembly. The assembly for clasping-escaping includes an L-shape subassembly having a vertical wall provided with backwards projecting, vertically spaced and inverted at 90? T-beams for connecting the L-shape subassembly to a parallelepipedic open box subassembly of a receptacle-terminal assembly. A bottom plate, located at the lowest part of the vertical wall extends outwardly. A passage above the bottom plate has a base terminating in a pair of serrations. The clasping-escaping includes a flat bar that after folding itself extends into a diverging strip provided with a multitude of serrations for meshing with the pair of serrations when a component is clasped. The parallelepipedic open box subassembly incorporates a plurality of T profile protrusions for connecting with the backwards projecting, vertically spaced and inverted at 90? T-beams.

  • Publication number: 20140276254
    Abstract: A patient warming and deep vein thrombosis system are provided. The system includes a first and a second compliant layer sealed together around an outer border to contain a warm liquid between the two layers and to form a wrap to surround and conform to a body portion of a patient. The wrap includes a plurality of flaps extends from opposite sides of a generally longitudinal central portion, such that one or more flaps from the opposite sides fasten to each other to surround the body portion. The flaps are openable during functional use to provide access to an underlying patient body surface. The system also includes a fluid control pump that directs the liquid through a continuous fluid flow path that extends between the two layers so as simultaneously to fill the wrap and apply pressure and heat to the body portion surrounded by the wrap.
