Description

  The present invention relates to a sensor attachment / detachment structure and a measurement display that can easily separate a biosensor from a measurement display attached with the biosensor.

  Conventionally, a measurement display that calculates and displays a measured value such as a blood glucose level by a biosensor has been used. And it is necessary to remove and discard the biosensor after measurement of blood sugar level, etc., but at this time there is a measuring device equipped with a sensor discharge mechanism for preventing the hand from touching the biosensor and causing an infection. Has been devised (for example, see Patent Document 1). According to this sensor discharge mechanism, the biosensor can be pushed out without touching the biosensor by hand by sliding the slide member with a finger.

However, it is difficult for a handicapped person to slide the slide member with a finger. Further, when the slide member does not slide smoothly, a great amount of force for sliding with the finger is required. Also, an unnatural movement of the finger was required to hold the measurement display with one hand and remove the biosensor.

The sensor attachment / detachment structure 10 according to the present invention is a sensor attachment / detachment structure that allows the biosensor 16 inserted and attached to the attachment port 14 of the measurement display 12 to be detached from the measurement display 12. The sensor attaching / detaching structure 10 includes a slide member 18 that can slide in a direction in which the biosensor 16 is pushed out, a push button 20 that can be pressed from the outside of the measurement display 12, a slide operation of the slide member 18, and a press operation of the push button 20. And a link mechanism 22 to be interlocked, and is a sensor attachment / detachment structure in which the slide member 18 is slid by the link mechanism 22 to push out the biosensor 16 when the push button 20 is pressed.

  The measurement indicator 12 of the present invention includes such a sensor attaching / detaching structure 10, and can attach a biosensor 16 to the attachment port 14 to measure a blood glucose level or the like and display it on the display unit 24. The biosensor 16 is inserted and attached to the attachment port 14 while being slid with the slide member 18 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 28 and the housing 30 fixed to the main body 26. The slide member 18 is provided with two guides 32 that come into contact with the housing 30, and the movement of the slide member 18 in the direction perpendicular to the direction in which the biosensor 16 is pushed out (Y direction in FIG. 1) is regulated by the guide 32. . Further, the movement of the slide member 18 in the Z direction in FIG. 2 is restricted by the substrate 28, the swing arm 38, and the housing 30.

  The push button 20 is provided so as to be slidable in the X-axis direction with respect to the bearing member 34 fixed to the substrate 28. When the push button 20 is not pressed, the push button 20 protrudes to the outside of the measurement display 12 as shown in FIG.

The link mechanism 22 includes a swing arm 38 that can swing back and forth around a pin 36 fixed to the substrate 28. On one end side of the swing arm 38, an engagement groove 42 in which the engagement pin 40 of the slide member 18 is engaged is provided. When the biosensor 16 is inserted into the attachment port 14 and the slide member 18 slides together with the biosensor 16, the link mechanism 22 is rotated clockwise to push the push button 20 to the outside of the measurement display 12. It is configured. The link mechanism 22 is configured to be rotated counterclockwise by the push button 20 to push the slide member 18 toward the outside of the measurement display 12 when the push button 20 is pressed. .

  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, the biosensor 16 is first inserted into the attachment port 14. The biosensor 16 inserted into the attachment port 14 slides along the bottom surface 44 of the housing 30 and then contacts the guide 32 of the slide member 18 to press the guide 32. When the guide 32 is pressed, the biosensor 16 and the slide member 18 slide along the substrate 28 and the housing 30, and as shown in FIGS. 1 and 2, the sensor electrode 46 of the biosensor 16 is a measurement indicator. 12 electrode terminals 48 are contacted. Further, when the engagement pin 40 of the slide member 18 presses the engagement groove 42 at one end of the swing arm 38, the swing arm 38 rotates clockwise, and the other end side of the swing arm 38 is the leg portion of the push button 20. 21 is pushed to push the push button 20 to the outside of the measurement display 12. When the sensor electrode 46 of the biosensor 16 comes into contact with the electrode terminal 48 of the measurement indicator 12, the movement of the biosensor 16 and the slide member 18 is regulated by pressing the biosensor 16 by the electrode terminal 48. 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 blood glucose level measurement is finished, the leg 21 of the push button 20 is moved as shown in FIG. 3 by pressing the push button 20 with the measurement display 12 held on the disposal container. The other end of the swing arm 38 is pressed, and the swing arm 38 rotates counterclockwise. When the swing arm 38 rotates counterclockwise, the engagement groove 42 presses the engagement pin 40 of the slide member 18, and the slide member 18 and the biosensor 16 are pushed out of the measurement display 12. When the slide member 18 and the biosensor 16 are pushed out of the measurement display 12, the pressing force to the biosensor 16 by the electrode terminal 48 is released, so that the biosensor 16 is attached by the pressing force by the slide member 18. Jump out of mouth 14 and leave. The detached biosensor 16 falls into a disposal container and is collected and discarded.

  In this way, by pushing the push button 20 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. Further, since the biosensor 16 can be detached only by pushing the push button 20 with a hand, even a person with a handicap can easily remove the biosensor 16 and discard it. Moreover, since only the push button 20 can be seen from the outside as the sensor attaching / detaching structure, it is preferable in terms of appearance.

Furthermore, the push button 20 can be pushed out of the measurement display 12 when the biosensor 16 is inserted and attached to the attachment port 14 only by the link mechanism 22 without requiring a spring or the like. When 20 is pressed, the biosensor 16 and the slide member 18 can be pushed toward the outside of the measurement display 12. For this reason, the biosensor 16 can be attached and detached with a compact configuration. Further, since the direction in which the push button 20 is pressed is opposite to the direction in which the biosensor 16 is pushed out, it is easy to grasp the direction in which the biosensor 16 is detached, which is preferable for safety.
