Patent number: 10921021Abstract: A blood warmer (10) has a first heating plate (12) and a second heating plate (14) as well as an exchangeable conductor (18, 20, 22, 24) for blood, which is arranged between the first heating plate (12) and the second heating plate (14). The blood warmer (10) has an inlet (66) and an outlet (68) for blood to which the conductor (18, 20, 22, 24) is fluidically connected. Due to the roughness of the surface (46) of the conductor (18, 20, 22, 24), an intermediate space (50) remains between the first heating plate (12) and/or the second heating plate (14) and the conductor (18, 20, 22, 24). A medium (52), which has a higher thermal conductivity than air, is at least partially statically arranged in the intermediate space (50). The blood warmer (10) may also have an electromechanical oscillating circuit and/or a vibration motor.Type: GrantFiled: March 22, 2017Date of Patent: February 16, 2021Assignee: WWT Technischer Geraetebau GmbHInventors: Klaus Schmider, Axel Stihler, Wolfgang Theilacker-Beck, Matthias Theilacker

Patent number: 9138548Abstract: A fluid warmer for tempering a medical fluid guided in a fluid line includes a first and second resistance heating element for alternating voltage and a heat exchanger thermally coupled to the two resistance heating elements and includes a holder for the fluid line. Each resistance heating element has a first and second electrical line connector, respectively, for connection of the resistance heating element to an alternating voltage source. Each electrical line connector has a respective drivable first switch. A respectively inversely phased alternating voltage or in-phase alternating voltage is applied to each resistance heating element during the tempering mode, wherein a compensation alternating voltage which is substantially inversely phased with respect to the heating alternating voltage is additionally applied to the heat exchanger using a compensation circuit.Type: GrantFiled: February 7, 2014Date of Patent: September 22, 2015Assignee: Stihler Electronic GmbHInventor: Axel Stihler

Patent number: 5474538Abstract: The apparatus for the heating of fluids exhibits a cylindrical heat exchanging body 10 which exhibits an outer groove 18 for the insertion of a conduit 20 through which the fluid is flowing. The groove 18 forms windings w with a heat transfer length l per winding w. With a fixed section length L to be warmed of the conduit 20, the heat transfer length l per winding w is at least increased by a factor of 1.4 or the heat exchanging cylinder 10 is directed largely horizontally and the diameter of the heat exchanging body 10 is larger or equal to 160 mm. (FIG. 1).Type: GrantFiled: January 17, 1995Date of Patent: December 12, 1995Assignees: Stihler Electronic medizinische Gerate Produktions, Vertriebs GmbHInventors: Axel Stihler, Wolfgang Theilacker-Beck

Patent number: 5138138Abstract: The heating system for an operating table comprises a multi-layer heating pad (2) having at least one heating segment (12a, 12b, 12c, 12d) which is adapted for being electrically heated and which is pervious to X-rays. A control and regulating unit (3) serving to control or regulate the heating current necessary for achieving an adjustable temperature of the heating pad (2) is connected to the heating pad (2). The heating pad (2) is equiped with a heating conductor (16) comprising a resistor (18) having a specific electric resistance and being wound in helical form about a carrier (17) made from an electrically non-conductive material which, regarding its mechanical properties, is rubber-elastic in the temperature range of between T=10.degree. celsius to T=200.degree. celsius. The different layers of the heating pad (2) are intimately bonded to form a composite material.Type: GrantFiled: July 26, 1990Date of Patent: August 11, 1992Assignee: Stihler Electronic Medizintechnische Gerate Prod. und Vertriebs-GmbHInventors: Wolfgang Theilacker, Hans-Peter Stihler, Axel Stihler, Josef Burkert

Patent number: 4709135Abstract: A device for heating infusion and transfusion solutions includes an automatically temperature controlled, electrically heated heat exchange unit having an exposed cylindrical outer surface provided with a helical groove removably receiving and holding with a clamping effect a flexible infusion tube through which the solution to be heated flows. A sleeve of thermal insulation material having its inner surface covered with an aluminum foil closely surrounds the outer surface of the unit and the tube seated in the groove. Safety clamps secured to casing portions at opposite ends of the heat exchange unit insure that the tube is held in the groove.Type: GrantFiled: September 20, 1985Date of Patent: November 24, 1987Assignee: Stihler Medizintechnik GmbHInventors: Kurt Dietrich, Axel Stihler, Wolfgang Theilacker
