ABSTRACT:
A valve and switch device for measuring pressure of liquids in living objects comprises a pressure converter which is hydraulically connected with the liquid to be measured, and which transforms the pressure to be measured into electrical signals. It transmits the signals to a measuring device for indication and/or registration. This measuring device has an electro-mechanical switch and valve mechanism for switching off to automatic zero balance and automatic calibration. The main device has a switchable valve unit connected to the pressure converter for supplying alternately to the pressure converter, by the shifting of an operating member, the pressure to be measured, a zero pressure for zero balancing, and possibly a reference pressure for calibration. The invention is particularly characterized, in that the operating member is connected with an electrical operating device arranged at the valve unit and operating the switching device of the measuring device simultaneously with the switching of the valve unit in such manner that, for zero pressure, it reaches the switch indication "zero balance", and, for reference pressure, it reaches the switch indication "calibration".
