Abstract

Abstract A small container such as a syringe or vial of fluid is inserted into a flow of temperature-conditioned gas to warm the fluid. The gas may be used, for example, to inflate a thermal care apparatus that exhausts the gas through a plurality of exhaust ports about a patient to envelop the patient in a warm bath. In one embodiment, the container is inserted into an inflatable chamber of the apparatus, and sealably held in place by a resilient aperture structure. In another embodiment, the container is inserted into through the aperture structure into a fluid supply hose that brings temperature-conditioned gas to the apparatus from a source. The aperture structure may comprise, for example, a selected pattern of perforations defined in the chamber or hose, or a layering of resilient material affixed to the chamber or hose with a suitably shaped aperture for receiving the container.
