<p>PURPOSE: To provide a biological zero readjusting assembly by which the zero readjustment can be performed from an external of an organism in a condition that a physiological pressure sensor is fixed in the organism. CONSTITUTION: A biological zero readjustment assembly 11 comprises a member 14, a passage 20 installed on an intermediate part of the member 14, a sensor 21 covering the passage, and a pressure connecting means 24. The sensor comprises the first side part 22 which receives the physiological pressure, and the second side part 23 at a side opposite to the first side part. The pressure connecting means comprises a curved passage 13. The passage 13 equalizes the pressure acting on the first and second side parts. The passage 13 prevents the communication of the liquid during the time when a standard value of a signal from the sensor is to be determined. The equalized pressure is generated when the passage 13 is positioned at the height almost same as the sensor.</p> |
