Abstract: The present invention relates to a device for flushing a body cavity with a fluid, the fluid being pumped by means of two lines from the body cavity. The respective pumping capacity is regulated via controllable pinch valves, the two pinch valves being coupled in an antiparallel manner.

Abstract: An emergency ventilator for artificially ventilating patients in the event of a medical emergency, having: —a housing with an ambient air suction opening and a ventilating gas outlet opening and —a fan which is designed and is arranged in the housing so as to convey ambient air from the ambient air suction opening to the ventilating gas outlet opening, wherein the fan includes a fan housing with an air conveyor which can be moved relative to the fan housing, and the fan housing is arranged in the housing in a fixed manner thereto; the fan housing is secured to the housing with the interposition of a heat conducting body, the heat conducting body including or being made of a material which is selected from light metal, nonferrous metal, and/or a plastic filled with a heat-conductive filler material.

Abstract: An exhalation valve arrangement includes an upstream breathing gas duct, which extends along a first duct path, a downstream breathing gas duct, which extends along a second duct path, and a valve assembly having a valve body and a valve seat, which valve assembly is provided such that, in the event of a predetermined first breathing gas overpressure in the upstream breathing gas duct relative to the downstream breathing gas duct. The valve assembly permits an exhalatory breathing gas flow from the upstream breathing gas duct to the downstream breathing gas duct and, in the event of a predetermined second breathing gas overpressure in the downstream breathing gas duct relative to the upstream breathing gas duct, the valve assembly blocks a gas flow from the downstream breathing gas duct to the upstream breathing gas duct.

Abstract: An exhalation valve for a ventilator apparatus for at least partial instrumental respiratory assistance of a patient, includes a valve housing with a flow passage which extends along a passage trajectory defining a local axial, radial and circumferential direction and along which respiratory air can flow through the valve housing. The valve housing has a housing-side valve sub-formation with a closed end surface which extends around the passage trajectory and towards which a mating surface of a valve body, movable relative to the valve housing and facing the end surface, can be pretensioned by the pretensioning force of a pretensioning device in such a way that the mating surface, when subjected to respiratory gas in an exhalation flow direction counter to the pretensioning force of the pretensioning device, is removable.

Abstract: The present invention relates to an exhalation valve (10) for a ventilator apparatus for at least partial instrumental respiratory assistance of a patient, comprising a valve housing (14) with a flow passage (16) which extends along a passage trajectory (D1, D2) defining a local axial, radial and circumferential direction and along which respiratory air can flow through the valve housing (14), wherein the valve housing (14) has a housing-side valve sub-formation with a closed end surface (24) which extends around the passage trajectory (D1) and towards which a mating surface (26) of a valve body (12), movable relative to the valve housing (14) and facing the end surface (24), can be pretensioned by the pretensioning force of a pretensioning device (58) in such a way that the mating surface (26), when subjected to respiratory gas in an exhalation flow direction (E) counter to the pretensioning force of the pretensioning device (38), is removable, with enlargement of an annular gap (42) which is present or can
