MEDICAL BLOOD CIRCUIT

PURPOSE:To facilitate manufacture, to reduce manufacturing cost and to repetedly use a probe for an electromagnetic flowmeter by attaching the coil part constituting the probe for the electromagnetic flowmeter to a medical conduit in a detachable manner. CONSTITUTION:A horizontal U-shape core 22 and the magnetic field generating coil 23 wound around the central part of the core 22 are embedded in a horizontal U-shape cover material 21a made of an epoxy resin. The cover material 21a is mounted so as to straddle the annular thick-walled part 20 provided to a connector cylindrical part 20a. The press part 21b provided to the cover material 21a on one end side thereof in a shakable manner by a shaft 21c is inwardly energized by a spring 21d to be fixed to the annular thick-walled part 20. Further, contacts 25A, 25B, 25C are fitted in the cover material 21a and the press part 21b so as to come into contact with the platinum electrodes 24A, 24B, 24C provided to the annular thick-walled part 20. By this constitution, even when a connector is discarded, the probe 21 for an expensive electromagnetic flowmeter can be detached from the connector main body for the sake of reuse.
