  • Anaesthetic controller
    Patent number: 6830047
    Abstract: For automatic supply of an active substance to a patient's body (14) the supply rate (R) of an infusion pump (13) is evaluated. The supply rate is processed in a patient model (11) which receives the corresponding active substance data from a drug data bank (12). The patient model (11) calculates the concentration (CNactual) in the patient's body from the former values of the active substance supply. Said actual concentration value is fed to a concentration controller (17) which also receives a desired concentration value (CNdesired). The infusion pump (13) is controlled as a function of the difference obtained. The desired concentration value can be manually set on an input device (19) or is supplied by another control portion which generates e. g. a BIS level or an adequate signal from the patient's EEG, the BIS level being a measure of the depth of anaesthesia.
    Type: Grant

  • Communications installation
    Patent number: 5410537
    Abstract: A number of peripheral controllers are connected to a PCM highway used exclusively for switching through signalling and packet data. Each controller has a counter indicating the usage factor. If the usage of one controller is too high, the next controller is activated.
