  • Apparatus for determining the pressure between a support dressing and a body portion surrounded by said support dressing
    Patent number: 4502491
    Abstract: An apparatus for determining the pressure between a support dressing and a body portion surrounded by said support dressing comprises a device for sensing the pressure, a device for indicating the pressure sensed and an arrangement transferring the pressure sensed to the device for indicating the pressure. The device for sensing the pressure may have a first part borne by the support dressing and a second part movable relative to the first one and being urged against the body portion by a spring or the like, the second part being connected to an indicator cooperating with a graduation through a lever system. The device for sensing the pressure may, however, also comprise a cavity filled with an incompressible fluid, said cavity being defined by a wall which is flexible at least in a region abutting the body portion.
