  • Device for picking off and evaluating a pressure, in particular a pressure of a fluid
    Patent number: 4928702
    Abstract: The invention relates to a device for picking off a pressure, particularly of a fluid, and to utilize it either for measuring or for transcodable signals.It comprises a capsule 1 which is provided with an opening 2 and which is closed by a flexible membrane 4, accessible to the pressure to be picked off, with said capsule 1 containing a non-compressible liquid 5.It is characterized in that it comprises compressible elastic means, positioned opposite the opening 2 and exerting a calibrated and invariable counter pressure on the non-compressible liquid 5 to assure the automatic and instantaneous returning of the flexible membrane 4 which closes the opening 2.The elastic compressible means can be formed by an air pocket 7 which may be separated from the opaque non-compressible liquid 5 by a non-compressible transparent liquid 23.The device is especially adapted to the measuring of arterial blood pressure.
