Publication number: 20230226307Abstract: An absorption arrangement (100) includes a CO2 absorber (4) and a water trap (2). Such an absorption arrangement (100) is used with a process for filtering carbon dioxide from a gas mixture by absorption. The gas mixture flows from a source through the absorption arrangement (100) to a sink in the following way: through a supply fluid guide unit (3), through a lower deflecting fluid guide unit (9), through the CO2 absorber (4), through an upper deflecting fluid guide unit (6), through a connecting fluid guide unit (33), through the water trap (2) and through a discharge fluid guide unit (34). The gas mixture flows vertically or obliquely upward through the CO2 absorber (4) and vertically or obliquely downward through the connecting fluid guide unit (33) to the water trap (2).Type: ApplicationFiled: January 4, 2023Publication date: July 20, 2023Inventors: Henryk SCHNAARS, Marcel PRIESKE

Patent number: 8997741Abstract: A respiration system feeds an anesthetic gas having, a density ?gas, with a Y-piece for connection to a patient, with a respiration circuit having an inspiration branch and an expiration branch, which extend away from the Y-piece. A first supply line from a branch in the expiration branch leads to an anesthetic gas discharge valve and a second supply line from the branch leads to a reservoir. A too high pressure, opposing expiration, cannot build up in the expiration branch and losses of anesthetic gas are kept to a minimum. A prestressing device exerts a prestressing force onto the valve body of the anesthetic gas discharge valve against the effect of gravity. The mass mvalve and the prestressing force determine a threshold pressure in the anesthetic gas discharge line that results in an opening of the anesthetic gas discharge valve.Type: GrantFiled: January 27, 2012Date of Patent: April 7, 2015Assignee: Dräger Medical GmbHInventors: Ralf Heesch, Henryk Schnaars

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
