  • Device for differential pressure measurement in anesthetic dispensing devices
    Patent number: 7591263
    Abstract: A device is provided for measuring the differential pressure in anesthetic dispensing devices, with which the differential pressure can be measured between two lines (2, 6) for supplying gaseous components to a mixing site (3). The device has at least one differential pressure sensor (11), which is connected with the lines (2, 6) for supplying the gaseous components. Buffer elements (12, 12?) are integrated in the connection between the lines (2, 6) for supplying the gaseous components and the differential pressure sensor (11).

  • Filling adapter for a metering device
    Patent number: 5911250
    Abstract: A filling adapter is provided for connecting a reservoir filled with a liquid with a metering device, which filling adapter has a liquid-specific connection piece for the reservoir. A code device is provided, detectable by the metering device, at least for the liquid contained in the reservoir. The code device is provided on the filling adapter in the connection area between the filling adapter and the metering device.

  • Gas dosing device for medical apparatus
    Patent number: 4542740
    Abstract: A gas dosing device for medical apparatus uses electrical control signals for connecting a gas supply under pressure through a pressure reducer to an outlet which is connected to the use load for the gas. The device includes a buffer connected between the gas source and the outlet and a reversing valve connected to the buffer and to the outlet. A pressure valve connected to the buffer and to the outlet. A pressure chamber is connected to the buffer and a measuring chamber is connected to the reversing valve. A differential pressure transducer has one connection to the pressure chamber and another to the measuring chamber and thus receives a differential of the pressure between these chambers.
