The device described consists of three sub-assemblies: a detector (S1), an amplifier (S2), and a recorder (S3) the detector (S1) measures pressures ranging from 0 to 7 600 mm/Hg, and withstands permanent overloads of 11 400 mm/Hg without any change in its characteristics. A specialized amplifier (S2) shapes the signal emitted by (S1). It has three measurement ranges: 1 900; 3 800 and 7 600 mm/Hg, and an automatic display of the values at T0/s and T60/s. A recorder connected to (S2), provides the track of the pressure signal. It has three recording speeds: 2.5, 5 and 10 mm/s. (S2) and (S3) are located in the same casing and form a single unit. The device according to the invention is particularly well-suited for measuring the pressure of a liquid injected into a compliant medium, such as a liquid compartment of the articular type or an intervertebral disc of humans or animals.
