Method and apparatus for fluid administration with distributed heating

Abstract

Disclosure is provided for apparatus and methods to control the temperature of fluids being administered to patients. The apparatus consists of an I.V. reservoir, fluid administration or I.V. tubing, an in-line heater, a heater controller, a temperature sensor located near the patient and feedback circuit connecting the temperature sensor to the heater controller. A method is disclosed which provides for overheating of the fluid so that it cools down to the desired temperature (usually body temperature) by the time it reaches the patient. In another embodiment, apparatus is disclosed for providing distributed heat to fluids being administered to patients. This apparatus includes heating channels or elements running along a length of the fluid administration tubing. These heating elements are controlled by a controller, which is attached to a temperature sensor, preferably located near the patient. The key advantages of this system include low cost, ease of use and reduced overheating of fluids prior to delivery to the patient. Such overheating could result in degradation of the fluids being delivered to the patient.
