PROBLEM TO BE SOLVED: To provide a pressure measuring system utilizable for re-sterilizing a suction pipe used for the lens surgery operation, using an autoclave sterilizer, thereby making it possible to re-use the pipe. SOLUTION: The pressure measuring system has a pipe 3 for flowing a fluid 4 and a diaphragm provided on a part 5 having a flat outer face 6 on a part of the pipe 3. The motion of the diaphragm, i.e., the pressure control characteristic is transferred to a pressure sensor. The diaphragm is connected no more removably to a protrusion 10 projecting from the pipe 3, the protrusion 10 has an extension member 12 extending in a direction approximately crossing the length 14 of the part 5 having the flat outer face and the extension member mechanically and separably acts on a force sensor as a pressure sensor. |
