Abstract:
1. A method for the operation of a pressure measuring device ( 10 ) for the measurement of the pressure in a system through which fluid flows, in particular in an extracorporeal circuit ( 20 ) of a medical unit, with the pressure measuring device ( 10 ) having a measuring chamber ( 12 ) which is bounded by a flexible membrane ( 13 ), through which fluid flows in the operation of the system or which is filled with fluid and also having a pressure sensor ( 14 ) connected to the membrane ( 13 ) for the purpose of pressure measurement, characterized in that the method includes the following steps not requiring any intervention of the staff: a. increasing the pressure in the measuring chamber ( b. separating the membrane ( c. joining together the membrane ( d. repeating the steps a, to c, at predetermined intervals and/or on the occurrence of an error case.
