Abstract: A connector is provided with a holding component, a support component, a terminal electrically connected to a contact of a guide wire held by the holding component, and a guide component rotatable around an axial line of the guide wire with respect to the support component. The holding component is provided with a body having an insertion hole for the guide wire and a holding piece extending along an axial line of the insertion hole from the body and capable of being elastically deformed inward in a radial direction with respect to the axial line. The guide component has a guide surface guiding the holding piece inward in the radial direction. The holding component is slid along the axis line of the insertion hole with respect to the guide component, whereby the holding piece abuts on the guide surface to be elastically deformed inward in the radial direction.

Abstract: A control circuit for a sensor provided in a long member which can be inserted into a lumen to measure the flow velocity of a fluid in the lumen and a measurement device. The control circuit includes a drive circuit supplying a drive current to the sensor. A leakage current detection circuit detects a leakage current and performs an output corresponding to the detected leakage current. The leakage current detection circuit outputs a detection signal in response to detection of a leakage current exceeding a threshold value. A stop circuit stopping supply of the drive current to the sensor by the detection signal is further provided.

Abstract: A connector (140) is provided with a holding component (141), a support component (148), a terminal (144) electrically connected to a contact of a guide wire (130) held by the holding component (141), and a guide component (147) rotatable around an axial line (130A) of the guide wire (130) with respect to the support component (148). The holding component (141) is provided with a body (150) having an insertion hole (150a) for the guide wire (130) and a holding piece (151) extending along an axial line of the insertion hole (150a) from the body (150) and capable of being elastically deformed inward in a radial direction with respect to the axial line. The guide component (147) has a guide surface (165a) guiding the holding piece (151) inward in the radial direction. The holding component (141) is slid along the axis line of the insertion hole (150a) with respect to the guide component (147), whereby the holding piece abuts on the guide surface (165a) to be elastically deformed inward in the radial direction.

Abstract: A blood measurement device having high bending rigidity and having excellent propulsion properties and rotational force transmission properties in a blood vessel. A blood measurement device has a tubular shaft having flexibility, a tubular connection portion positioned coaxially with the distal end of the shaft and having an inner diameter larger than the inner diameter of the shaft, a slit communicating the inside and the outside of the connection portion, a tubular tip guide portion having flexibility coaxially connected to the distal end of the connection portion, a core material having flexibility fitted into the connection portion and extending to the distal end in the internal space of the tip guide portion to be connected to the tip guide portion, a measurement element positioned in the internal space of the tip guide portion and measuring the physical quantity of blood, and a signal wire which is extended from the measurement element to be inserted into and passed through the internal space of the shaft through the slit.
