Patent number: 11623064Abstract: A dispensing device for dispensing anesthetic in a breathing gas stream includes a flow duct (42) for an anesthetic-containing breathing gas stream, a control unit (5) and a first temperature sensor (54). An anesthetic feed device (45) has an evaporation surface (46) arranged in the flow duct (42). The first temperature sensor (54) detects the temperature of the evaporation surface (46) and sends a first temperature signal (T1) to the control unit (5). A second temperature sensor (53) detects the temperature of the breathing gas stream in the flow duct (42) and sends a second temperature signal (T2) to the control unit (5). The control unit (5) is configured to determine an anesthetic concentration based on the first and second temperature signals (T1, T2).Type: GrantFiled: July 13, 2017Date of Patent: April 11, 2023Assignee: Drägerwerk AG & Co.

Publication number: 20140135569Abstract: An incubator (12) includes an incubator hood (11) with two side walls (2, 3), a front wall (4), a rear wall (5) and preferably an upper wall (6), which have each inner and outer surfaces. One or more of the inner and/or outer surfaces of one or more of the walls (2, 3, 4, 5, 6) of the incubator hood are provided with a coating. The coating is electrically conductive and essentially optically transparent. The electrical conductivity of the coating is designed to heat the coated walls, similarly to a resistance heater, to a desired temperature by applying an electric voltage in order to prevent thereby water of condensation from forming. The coating is essentially scratch resistant.Type: ApplicationFiled: November 8, 2013Publication date: May 15, 2014Applicant: Dräger Medical GmbHInventors: Hans-Ullrich HANSMANN, Michael RIECKE, Henryk SCHNAARS

Patent number: 8146593Abstract: A process and a device are provided for separating carbon dioxide from a breathing gas mixture by means of a “Fixed Site Carrier” membrane. The breathing gas mixture is guided in the device on a side of a selective, semipermeable membrane, which is provided with amine groups, which are bound covalently to a polymer. Through the membrane, the transport of the components of the gas mixture can take place. The membrane is selected to be such that the permeability for CO2 is substantially higher than the permeability for the other gas components of the breathing gas mixture. The membrane has or is associated with means for guiding the gas, which acts to guide the gas mixture on one side along the membrane. The membrane separates volume areas in which different CO2 partial pressures prevail from one another.Type: GrantFiled: September 6, 2007Date of Patent: April 3, 2012Assignee: Dräger Medical GmbHInventor: Michael Riecke
