Abstract:
1. A method for producing a heating device which covers and controls a temperature of a medical instrument, the method comprising the steps of: a) co-extruding, in a single extrusion process, an inner heating profile, made from a heat-conducting elastic material, and an outer coating, made from a heat-insulating material, an inner surface of the outer coating thereby being connected to an outer surface of the heating profile with material fit, wherein the heating profile and the outer coating define at least one cavity which extends along an entire axial extension thereof and which can be accessed from an outside for insertion of the medical instrument and the heating profile defining at least one axial bore which extends along an entire length thereof, the at least one axial bore having an axial bore diameter, wherein the cavity and the axial bore are separated from each other, along an entire axial length of the heating profile, by a thickness of the elastic material from which the heating profile is made; b) selecting a temperature control element, the temperature control element having an outer surface with an outer surface diameter that is larger than the axial bore diameter; and c) inserting, following steps a) and b), the temperature control element into the axial bore of the heating profile, thereby widening the axial bore, wherein the widened axial bore presses inwardly in a substantially radial direction against the outer surface of the temperature control element thereby establishing good thermal contact between the temperature control element and the heating profile.
