Abstract

A thermal therapy garment that covers at least the lower extremities of a patient. The garment has an air impermeable outer layer and an air permeable inner layer. An inflatable air chamber is defined between the inner and outer layers. An inlet port connects to the chamber to allow inflation with conditioned air, which is exhausted through the inner layer over a selected region of the patient's lower body. A gown has a length sufficient to overlap a waist portion of the garment, The gown has an opening that coincides with the inlet port, thereby allowing a hose to pass through the gown and connect to the inlet port. In one embodiment, the gown has sleeves and/or a posterior portion that are heat reflective whereby the extremities are warmed to minimize the core to peripheral temperature gradient.

Dependent claims

A system configured to warm a patient to prevent redistribution hypothermia, comprising:

a garment configured to cover a lower body portion of the patient, the garment including:
a pair of leg portions, each leg portion having a leg flow configured to move air in a direction downward from the pair of leg portions;
a waist portion having a waist flow configured to move air in a direction upward from the waist portion;
a first surface that is air permeable and proximate the patient when the patient is wearing the garment, each of the pair of the leg portions having a plurality of perforations along the first surface;
a second surface that is air impermeable and, being an outside surface of the garment;
an air chamber formed between the first surface and the second surface, the air chamber dimensioned and shaped to expand as air is supplied to the garment;
and
an inlet port penetrating the air chamber, wherein
when an air hose is connected to the inlet port the air chamber is configured to receive conditioned air, the conditioned air being provided to the air chamber at a temperature of at least 36 degrees celsius, and
each of the pair of leg portions dimensioned and shaped to provide convective heating directly to legs of the patient, and the waist portion dimensioned and shaped to provide conductive heating within the garment;
and
a gown configured to cover an upper body portion of the patient and having a length sufficient to create an overlap portion that overlaps the waist portion of the garment when the garment and the gown are worn by the patient, the gown having an opening through the overlap portion from an exterior side to an interior side of the gown, the opening being dimensioned and shaped to accommodate the air hose when the air hose is connected to the inlet port.
