[0108] Hereinafter, the first embodiment of the present invention will be described. figure 1 The illustrated blood measurement device 50 can be used, for example, to measure physical quantities such as blood pressure in a blood vessel of a living body. The blood measurement device 50 has a tubular shaft body 10 and a tubular distal end guide 20 provided at the distal end (corresponding to the front end) of the shaft body 10 . The distal end guide portion 20 is provided with a measuring element 27 ( figure 2 refer to). A control device 40 as an external device is connected to the proximal end (corresponding to the proximal end) of the shaft body 10 . The control device 40 performs control of power supplied to the measurement element 27 , processing of signals emitted from the measurement element 27 , and the like.
[0109] The shaft body 10 is a flexible tube body. The shaft body 10 has a length suitable for measuring blood pressure at a desired position of the blood vess...
no. 2 Embodiment approach
[0137] Hereinafter, a second embodiment of the present invention will be described. In the aforementioned first embodiment, the connecting portion 12 is formed integrally with the shaft body portion 11 , but in the connecting portion of the present invention, the shaft body 10 may be formed as another member. In addition, in the following description, the members with the same reference numerals as those in the first embodiment refer to the same members.
[0138] like Image 6 As shown, the shaft 60 has a shaft body portion 61 and a boss portion 62 formed on the distal end of the shaft body portion 61 . The shaft body portion 61 is a tubular body whose outer diameter is substantially constant over the entire axial direction. The inner diameter of the inner space 63A of the shaft main body portion 61 is fixed over the entire axial direction. The boss portion 62 protrudes in the axial direction from the distal end of the shaft main body portion 61 . The boss portion 62 is in...
no. 3 Embodiment approach
[0163] Measuring device 100 such as Figure 9 shown. The measurement device 100 is a device that measures the flow velocity of blood flowing in a human blood vessel. In the measurement device 100 , the AC-DC adapter 111 and the personal computer 112 are connected by a cable 113 . In addition, the flow velocity of blood is an example of the physical quantity of blood.
[0164] The AC-DC adapter 111 is a converter that converts a commercial AC voltage (eg, AC 100V) into a DC voltage (eg, DC15V) and outputs it. In addition, the AC-DC adapter 111 can be assembled into the measurement device 100 to be a part of the measurement device 100 .
[0165] The personal computer 112 has analysis software installed. The analysis software analyzes the signal input to the personal computer 112 from the measurement device 100 and displays it on the display.
[0166] The measurement device 100 includes an AC-DC adapter 111 , a main body 120 connected to the personal computer 112 , and a gui...
