Method of heating medical liquids
First Claim
1. A method of heating a fluid to a temperature appropriate for administration to a patient while said fluid is being transferred from a fluid reservoir to said patient, which comprises:
- a. providing a fluid supply conduit through which said fluid is passed from said reservoir to be administered to said patient;
b. providing a first elasticized device comprising an elongated flexible elasticized band having incorporated therein at least one internal chamber in which is disposed a semi-solid heat-absorbing and -emitting composition having a relatively high heat capacity;
c. pre-heating said composition within said elasticized device to a predetermined desired temperature;
d. wrapping said device around a predetermined length of said conduit; and
e. retaining said device in place by quick release fastening means;
such that said pre-heated composition within said device transfers heat to said adjacent conduit thereby heating said fluid passing through said conduit from said reservoir to said administration temperature immediately prior to administration of said fluid to said patient.

Abstract
A simple and cost-effective method is disclosed to avoid hypothermia and other adverse effects of administration of chilled fluids such intravenous medicating fluid, an intravenous hydrating fluid or blood to a patient during medical procedures such surgery and post-operative recovery. The method provides heat to such fluids, using an elasticized heating device such that each unit can be quickly and easily replaced with another unit when the heating effect of the first significantly diminished, so that the fluid administered is kept at the desirable administration temperature during the entire surgical procedure. The method involves providing a conduit through which the fluid is administered to the patient (usually intravenously or subcutaneously), providing the elasticized device incorporating a semi-solid composition with a relatively high heat capacity, pre-heating the composition to administration temperature; wrapping the device around a length of the conduit; and retaining the device in place by quick release fasteners, so that the pre-heated composition heating the fluid passing through the conduit to the desired temperature immediately prior to administration of the fluid to the patient. Use of two or more devices simultaneously is also disclosed. Further, as the heat content of one device is depleted, the method also includes quick replacement of that device with another, previously pre-heated, so that the heating of the fluid continues substantially continuously at the desire temperature.
