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.

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.

Abstract: The present invention provides a method for reducing condensed humidifying agent in a humidification system by pulsing a delivery of humidifying agent into a respiratory circuit. During a non-pulsed interval, gas flowing through the respiratory circuit will evaporate the condensed humidifying agent present in the respiratory circuit. The present invention also provides a method and apparatus for delivering humidified gas to a patient, wherein the delivery avoids the problems associated with a stationary water humidifier. In the method, the delivery of humidifying agent is precisely controlled to deliver a flow of humidifying agent to a volume of gas.

Abstract: A connection device for a patient warming system is provided. The device includes a first connector port and a second connector port that each includes a wall that circumferentially defines a longitudinal channel. The first and second connection ports are each configured to receive a tubing that leads to a patient warming device. A self-sealing valve is aligned in each of the longitudinal channels to engage an inlet and outlet port of a control unit of the patient warming system. A planar base member of the connection device joins the second end of the first connector port generally parallel to the second end of second connector port. The connection device also includes a flexure member with a first catch mechanism that releasably secures the connection device to the control unit of the patient warming system.

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.
