Disposable thermostatically controlled electric surgical-medical irrigation and lavage liquid warming bowl and method of use

摘要

A warming bowl for electrically heating lavage and irrigation liquid for use during medical-surgical procedures includes an electric heating device and an automatic thermostatic control to heat and maintain the liquid at a substantially constant temperature. The warming bowl is disposable after use and has an inner and an outer bowl sealed to one another so as to provide an internal sealed region therebetween for holding a battery to power the electric heating device. The inner bowl serves to hold irrigation liquid and supports therein a housing made of low-thermal-conductivity material that houses the electric heating device and the thermostatic control in spaced, substantially thermally isolated relation from one another. A metallic thermal shunt conductor is disposed along and in contact with a portion of the external periphery of the housing and extends over and across the space between the heating device and the thermostatic control. The housing is fixedly supported spacedly above the inner bowl's bottom. When the inner bowl is filled with irrigation liquid, a major portion of the housing is exposed to the liquid at least over a substantial part of the outer surface of the shunt conductor. An external power source can be selectively optionally connected to power the heating device.
