  • Publication number: 20190298965
    Abstract: 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).

  • Publication number: 20190232015
    Abstract: A gas heater (1) and gas heater method heat a carrier gas flow. The gas heater includes a gas inlet (2) a gas outlet (3) and a connecting gas channel (4). A heating system (5), arranged in the gas channel, includes a heat exchanger (12) surface. The carrier gas at least partly flows over the surface to heat the carrier gas flow. The gas channel includes a first section (6), arranged upstream of the heat exchanger in a flow direction, and a second section (7) arranged downstream of the heat exchanger. A respective sensor (8a, 8b), for detecting a pressure value, is in the first and the second section or directly adjacent thereto. Pressure values are transmitted to a control and analysis unit (9) which ascertains a mass and/or volume flow of the carrier gas in the gas channel based on a pressure difference between the two pressure values.

  • Publication number: 20170151412
    Abstract: A device, for dispensing an anesthetic into a gas stream, has a gas inlet, via which gas to be enriched with anesthetic and coming from a gas source flows in and with a gas outlet, via which gas enriched with anesthetic flows out to a patient port. A heating element, for heating the gas stream, is arranged upstream of an evaporation chamber, for dispensing an anesthetic into the gas stream, between the gas inlet and the gas outlet. The heating element is actuated by a control unit such that heat is fed to the gas to be enriched with anesthetic for evaporation of the anesthetic located in the evaporation chamber as a function of at least one status parameter of the gas to be enriched with the anesthetic and/or of the gas at least partially enriched with the anesthetic.
