Compressive patient warming device

摘要

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.

1. A compressive patient warming device comprising:
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 attached to and covering the inner layer to form a space to hold a heat transfer medium between the inner layer and the outer layer while the inner layer is wrapped around the appendage; and an intermediate layer sealed to the outer layer at an outer border and disposed between the inner layer and outer layer, the outer layer being attached to the inner layer via the intermediate layer, and wherein: the intermediate layer and outer layer form a wrap comprising:
a generally longitudinal central portion sized to cover a surface of the appendage, anda continuous fluid flow path extending between the intermediate layer and the outer layer between a fluid inlet and a fluid outlet so as simultaneously to inflate the wrap and apply pressure and heat to a body portion being surrounded by the wrap, and wherein the inner layer comprises a tight fitting elastic sleeve attached to the intermediate layer along a longitudinal axis of the central portion of the wrap and is configured to slide onto the appendage.
