  • Patent number: 10821256
    Abstract: A method and device, for enriching a gas flow with an anesthetic, include a gas mixer (1), with gas inlets (2a, 2b) and one or more gas outlets (3a, 3b), and an anesthetic dispenser (4) connected to the one or more gas outlets. The anesthetic dispenser at least partially enriches the gas flow to provide a breathing gas flow enriched with anesthetic at a patient connector (5). A control valve (7a) is arranged fluidically in series with the anesthetic dispenser (4). The gas outlet is connected to the patient connector (5) via a gas channel (8), arranged fluidically parallel to the anesthetic dispenser (4) and in which at least another control valve (7b) is arranged. A control unit (6) actuates at least one control valve as a function of a desired value for an anesthetic concentration in the breathing gas flow to change anesthetic concentration at the patient connector (5).

  • Patent number: 10722677
    Abstract: A wick (12) includes a porous molding, which has a plurality of air ducts (26) extending in the vertical direction, a plurality of upper deflection chambers (28), which connect each a first air duct pair (29) of the plurality of air ducts (26) to one another, and a plurality of lower deflection chambers (30), which connect each a second air duct pair (31) of the plurality of air ducts (26) to one another. The two air ducts (26) of the second air duct pairs (31) are each associated with different first air duct pairs (29). An anesthetic evaporator (10) includes a housing (14, 16), which receives the wick (12), so that the vertical air ducts (26) and the upper and lower deflection chambers (28, 30) form an air flow duct between the air inlet (22) and the air outlet (24).

  • Patent number: 10682485
    Abstract: An anesthetic dispensing device (1), to which a carrier gas stream is fed for enriching with anesthetic, has the gas stream split into two partial gas streams, one of which flows through a bypass channel (7) unchanged and the other of which is fed to an evaporation chamber (9), where the partial gas stream is saturated with anesthetic. In a mixing point (6), both partial gas streams are mixed to form an anesthetic gas stream, which leaves the anesthetic dispensing device through the anesthetic gas outlet (4). A control unit (2) is provided that is configured to generate a control signal for an electric motor drive (14) for adjusting the valve opening of the valve element (15) on the basis of a concentration of the anesthetic in the anesthetic gas needed at the anesthetic gas outlet (4) and at least one temperature-specific correction factor.

  • Patent number: 8490621
    Abstract: A device is provided for increasing humidity for respirating patients, especially for a respiration humidifier or an anesthesia reflector. The device includes a gas channel for passing through breathing air, a control and/or regulating device, a temperature sensor and a dew sensor for measuring the humidity present in the breathing air by electromagnetic radiation with a generating device and with a detection device for electromagnetic radiation. The humidity of the breathing air is determined at a low cost and in a reliable manner and condensation is avoided in the respiration system without any additional effort for sterilization. Humidity in the breathing air is determined by the a dew sensor by the change in the reflection of the electromagnetic radiation as a function of dew formation at a condensation-fogged and condensation-free boundary surface between breathing air and a medium having an optical density higher than that of breathing air.

  • Patent number: 7942389
    Abstract: An evaporator defines an evaporator volume, and boils the liquid inside evaporator volume. A mixing chamber is in communication with the evaporator volume and mixes the vapor or moisture from the liquid in the evaporator with the breathing gas of the patient. The mixing chamber is a separate structure than the evaporator. The mixing chamber and the evaporator are connected by a first connection that is repetitively connectable and disconnectable without significant destruction of a respective connection. A heater is arranged outside of the evaporator and in a heat conducting connection with the evaporator. The heater is a separate structure than the evaporator. The evaporator and the heater are connected by a second connection that is repetitively connectable and disconnectable. A liquid storage tank is in communication with the evaporator and supplies a liquid to the evaporator through a flow channel. The liquid storage tank is larger than the evaporator.
