Title:
REMOVABLE PRESSURE SENSOR AND EXTRACORPOREAL CIRCULATION DEVICE PROVIDED WITH REMOVABLE PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/104158
Kind Code:
A1
Abstract:
[Problem] To provide a removable pressure sensor and extracorporeal circulation device provided with the removable pressure sensor, which make it possible to easily and yet also quickly and safely measure the circuit internal pressure of liquid circulating through a circuit. [Solution] A removable pressure sensor 30 is provided with a main body 31 and a pressure sensing element 40 disposed on the main body 31. The main body 31 comprises: a base 32 having a tube-mounting recess 34 into which a midway section of a tube 11 (12, 19) is removably inserted so as to elastically deform the tube 11 (12, 19), allowing the pressure sensing element 40 to sense the circuit internal pressure of liquid within the tube 11 (12, 19); and a cover 33 for closing off the tube-mounting recess 34 of the base and thereby retaining the tube 11 (12, 19) within the tube-mounting recess 34. The tube-mounting recess 34 has a rectangular cross-section, and the width L of the rectangular cross-section is set so as to be smaller than an external dimension D of the tube.
