Filed:

Mar 13, 2013

Appl. No.:

13/801270

Inventors:

Christopher M. Varga - Laguna Hills CA, US
Michael McMahon - Yorba Linda CA, US
Thomas Dillingham - Aliso Viejo CA, US
James Chan - San Marino CA, US
Todd Schmaltz - San Diego CA, US
Noah Meade - Grayslake IL, US

International Classification:

A61F 7/02

US Classification:

601 15

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.

International Classification:

US Classification:

607104

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.
