  • Patent number: 8997741
    Abstract: 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.

  • Publication number: 20140135569
    Abstract: 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.

  • Publication number: 20140060537
    Abstract: A device (10) for the mechanical respiration of a patient (12) has a gas delivery device (14), which includes a flow module (16) for generating a gas stream (A), a gas outlet (24) and a gas inlet (34). The device (10) includes a gas-carrying short-circuiting unit (56), by which the gas outlet (24) and the gas inlet (34) can be coupled with one another to short-circuit the gas delivery device (14), and a plasma generator (62) coupled into the short-circuited gas delivery device (14) for enriching the gas stream (A) generated in the short-circuited gas delivery device (14) with a disinfecting plasma.
