  The measurement indicator 12 of the present invention includes the sensor attaching / detaching structure 10 as described above, and can attach a biosensor 16 to the attachment port 14 to measure a blood sugar level or the like and display it on the display unit 26. The biosensor 16 is inserted and attached to the attachment port 14 while being slid with the slide member 18 against the urging force in the direction opposite to the pushing direction.

  The slide member 18 is provided so as to be slidable in the direction in which the biosensor 16 is pushed out or in the opposite direction with respect to the substrate 30 and the housing 32 fixed to the main body 28. The slide member 18 is provided with a guide 34 that contacts the housing 32 and a groove 38 that contacts the pin 36 fixed to the substrate 30, and is perpendicular to the direction in which the biosensor 16 of the slide member 18 is pushed out (FIG. 3). Motion in the Y direction) is regulated by the guide 34 and the groove 38. Further, a T-shaped hole 48 including a groove 42 slidable with respect to the leg portion 40 of the push button 24 and an engagement hole 46 that is continuous with the groove 42 and into which the claw portion 44 of the locking member 22 can be inserted. Is provided.

  The spring 20 is provided between the fastener 50 fixed on the substrate 30 and the slide member 18. The locking member 22 is made of an elastic member, and the base opposite to the claw portion 44 at the tip is fixed to the back side of the substrate 30. The locking member 22 is straight when no load is applied, and the claw portion 44 at the tip of the locking member 22 is inserted into the engagement hole 46 of the slide member 18 through the hole 31 of the substrate 30. Is possible. On the other hand, the locking member 22 is elastically bent downward by being pressed from above by the leg portion 40 of the push button 24, the claw portion 44 is released from the engagement hole 46, and the slide member 18 is The biosensor 16 is slid in the pushing direction by the biasing force of the spring 20.

  While the push button 24 is normally positioned above the T-shaped hole 48 by the biasing force of the spring 52, the leg portion 40 is inserted into the engagement hole 46 by being pressed from the outside of the measurement indicator 12. Thus, the claw portion 44 of the locking member 22 is configured to be pushed out from the engagement hole 46. That is, the push button 24 pushes the locking member 22 out of the engagement hole 46 against the elastic force of the locking member 22 by applying a pressing force from the outside of the measurement indicator 12, and no pressing force is applied. In this case, the locking member 22 is pushed back in conjunction with the operation of inserting the locking member 22 into the engagement hole 46 by the elastic force of the locking member 22. Since the push button 24 is pushed back by using the elastic force of the locking member 22, it is not necessary to provide an urging means for pushing the push button 24 back. When the leg portion 40 pushes the claw portion 44 of the locking member 22 from the engagement hole 46, the slide member 18 slides in the direction to push out the biosensor 16 by the biasing force of the spring 20, and the groove is formed in the groove with respect to the leg portion 40. 42 slides.

  When the biosensor 16 is attached to the sensor attaching / detaching structure 10 and the measurement display 12 and the blood glucose level is measured, first, the biosensor 16 is inserted into the attachment port 14 as shown in FIGS. As shown in FIGS. 2 and 3, the biosensor 16 inserted into the attachment port 14 slides along the bottom surface 54 of the housing 32 and then contacts the guide 34 of the slide member 18 to press the guide 34. At this time, as shown in FIG. 2, the slide member 18 presses the claw portion 44 of the locking member 22. When the guide 34 is pressed, the biosensor 16 and the slide member 18 slide along the substrate 30 and the housing 32, and as shown in FIG. 4A, the sensor electrode 56 of the biosensor 16 is a measurement indicator. 12 electrode terminals 58 are contacted. When the sensor electrode 56 of the biosensor 16 contacts the electrode terminal 58 of the measurement indicator 12, the claw portion 44 of the locking member 22 is inserted into the engagement hole 46 of the slide member 18 through the hole 31. Thus, the movement of the biosensor 16 and the slide member 18 is regulated. The movement of the biosensor 16 and the slide member 18 is also restricted by pressing the biosensor 16 with the electrode terminal 58. Further, as shown in FIG. 2, the movement of the biosensor 16 in the Z direction is restricted by narrowing the attachment port 14 side of the housing 32. In this manner, with the biosensor 16 attached to the measurement display 12, blood is attached to the tip of the biosensor 16 and the blood sugar level is measured.

  After the measurement of the blood sugar level is completed, the push button 24 is pressed while the measurement display 12 is held on the disposal container or the like, so that the leg of the push button 24 is shown in FIG. The portion 40 pushes the claw portion 44 of the locking member 22 downward from the engagement hole 46 of the slide member 18. The restriction of the slide member 18 is released by pushing out the claw portion 44 from the engagement hole 46, and the biosensor 16 and the slide member 18 are moved along the substrate 30 and the housing 32 according to the biasing force of the spring 20. Slide in the direction to push out. Note that the biasing force of the spring 20 is larger than the frictional force due to the pressing force of the electrode terminal 58 against the biosensor 16, so that the biosensor 16 and the slide member 18 slide. At this time, the groove 42 slides with respect to the leg portion 40 of the push button 24, and the end of the groove 42 hits the leg portion 40, whereby the slide member 18 stops at the position shown in FIGS. 2 and 3. The slide member 18 also stops when the end of the groove 38 hits the pin 36. On the other hand, since the pressing force applied to the biosensor 16 by the electrode terminal 58 is released immediately before the slide member 18 stops in this way, the biosensor 16 jumps out of the attachment port 14 due to the pressing force by the slide member 18. break away. The detached biosensor 16 falls into a disposal container and is collected and discarded.

  In this way, by pushing the push button 24 by hand, the biosensor 16 can be detached from the measurement display 12 and discarded without touching the biosensor 16 by hand. For this reason, the infection by the blood adhering to the biosensor 16 can be prevented, and safety can be improved. In addition, since the biosensor 16 can be detached only by pushing the push button 24 by hand, even a person with a disability can easily remove the biosensor 16 and discard it. Moreover, since only the push button 24 can be seen from the outside as the sensor attaching / detaching structure, it is preferable in terms of appearance.
