[0012]
In FIG. 1, reference numeral 10 denotes a sensor mounting structure according to the present invention, and reference numeral 12 denotes a measurement display according to the present invention. The measurement indicator 12 is a device that calculates and displays a blood glucose level by attaching a sensor unit 16 having a biosensor 14 in a measurable state, and includes a sensor attachment structure 10 at a distal end portion 18 of the main body.
[0013]
The sensor mounting structure 10 includes a holding unit 20 fixed to the main body tip 18 so as to hold the sensor unit 16 in a measurable state, and the sensor unit 16 held by the holding unit 20 is slid from the holding unit 20. And detachment means 22 for detachment.
[0014]
As shown in FIG. 1, the holding means 20 includes a hollow portion 24 for inserting and holding the sensor unit 16. As shown in FIG. 2A, the hollow portion 24 is configured in a shape having a substantially square cross section by a socket 26 fixed to the main body tip 18 and a slide fitting 28 slidably attached to the main body tip 18. The That is, the socket 26 shown in FIG. 3 forms the upper side and the lower side of the substantially square cross section, and the slide fitting 28 shown in FIG. Two terminals 29 are provided on the U-shaped inner surface of the socket 26.
[0015]
Further, as shown in FIG. 1, the holding means 20 includes two cantilever beams (engagement members) 42 that are engaged with the sensor unit 16. The cantilever 42 is made of an elastic member, and is configured to be engaged with the engagement protrusion 44 of the sensor unit 16 while being elastically deformed. As shown in FIG. 2B, the cantilever 42 is a fixed support in which one end 46 is fixed to the main body tip 18, and the other end 48 is a free position located in the hole 50 of the main body tip 18. At the end.
[0016]
The detaching means 22 pushes the sensor unit 16 by sliding integrally with the slider 30 shown in FIG. 5 that slides against the biasing force of the spring 52 in the direction opposite to the insertion direction of the sensor unit 16. 4 and a slide fitting (pressing member) 28 shown in FIG. The slider 30 is provided with a curved surface 34 for sliding by pressing a finger. The slide fitting 28 is configured such that the sensor unit 16 can be pushed out by a pair of pushing members 36.
[0017]
Further, an LS (limit switch, insertion detection means) 40 for detecting the insertion of the sensor unit 16 is provided on the P board 38 of the main body tip 18. That is, the LS 40 is provided on the back surface side of the measurement indicator 12 in the hollow portion 24.
[0018]
The operation of the sensor mounting structure 10 and the measurement display 12 will be described below.
[0019]
A person who performs a blood glucose level test using the measurement display 12 including the sensor mounting structure 10 first prepares a sensor unit 16 having a biosensor 14. The sensor unit 16 is not particularly limited as long as the sensor unit 16 can be attached to the measurement display 12 in a measurable state. In the present embodiment, as an example of the sensor unit, the sensor unit 16 configured to cover the biosensor 14 by inserting the biosensor 14 into the sensor cover 80 and attaching the sensor cap 82 as shown in FIG. The case of using will be described.
[0020]
Next, the sensor unit 16 is held, and the sensor unit 16 is inserted into the hollow portion 24 of the measurement display 12 as shown in FIGS. 7 and 8. At this time, as shown in FIG. 7B, the engagement projection 44 of the sensor unit 16 is engaged with the cantilever 42, whereby the sensor unit 16 is positioned and fixed to the hollow portion 24. Further, as shown in FIG. 8B, when the convex portion 60 on the back surface of the sensor unit 16 presses the LS 40 or contacts or approaches the LS 40, the LS 40 detects that the sensor unit 16 is positioned and fixed. . The fact that the sensor unit 16 is positioned and fixed is displayed by display means (not shown). The person who performs the blood glucose level test can recognize that the sensor unit 16 has been positioned and fixed by this display. Further, since the LS 40 is configured to react by the convex portion 60 on the back surface of the sensor unit 16, it can be recognized that the sensor unit 16 has been properly positioned and fixed without misidentifying the front and back.
[0021]
Next, as shown in FIG. 9, the person who performs the test opens a hole in the finger 64 with a needle to give blood 66 as a specimen. On the other hand, the measurement indicator 12 to which the sensor unit 16 is attached is held by hand, the sensor cap 82 is removed, and the inflow portion 68 of the biosensor 14 is brought into contact with the blood 66. The blood 66 in contact with the inflow portion 68 flows into the specimen holding portion 70 by capillary action. The measurement indicator 12 measures the blood glucose level of the blood 66 via the terminal 29 and displays it after a certain time.
[0022]
When the measurement of the blood glucose level is completed in this way, the sensor cap 82 is attached to the sensor unit 16 again, and the slider 30 is pressed with a finger so that the slider 30 is biased by the spring 52 as shown in FIG. Slide against. By sliding the slider 30, the slide fitting 28 slides integrally, and the pair of pushing members 36 of the slide fitting 28 push out while sandwiching the sensor unit 16. When the pushing member 36 pushes out the sensor unit 16, the sensor unit 16 is detached from the hollow portion 24 as shown in FIG. 10B, and the sensor unit 16 is detached from the measurement display 12.
[0023]
As mentioned above, although embodiment of this invention was described based on drawing, this invention is not limited to what was illustrated. For example, the detaching means is not limited to being manually detached, and may be detached by an urging force of an elastic body or a driving force of a driving means. Moreover, the shape of the measurement display of this invention is not specifically limited, What is necessary is just to include the sensor attachment structure of this invention. The application of the present invention is not limited to blood glucose level testing, and may be widely used for medical, biological, chemical testing or testing. Moreover, blood tests other than blood sugar levels may be used.
[0024]
In addition, the technical scope of the present invention includes embodiments in which various improvements, modifications, and variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Moreover, you may implement with the form which substituted any invention specific matter to the other technique within the range which the same effect | action or effect produces.
[0025]
【The invention's effect】
According to the sensor mounting structure and the measurement display of the present invention, the sensor unit can be detached from the measurement display by the detaching means after the blood glucose level or the like is measured. For this reason, the person who performs the inspection can remove the sensor unit without touching the sensor unit, and can prevent infection with a viral disease such as hepatitis.
[0026]
Further, according to the sensor mounting structure and the measurement display of the present invention in which the detaching means includes the slider and the pressing member, the sensor unit can be smoothly detached by the slide mechanism. In addition, since the sensor unit is a mechanism for manually sliding the sensor unit, it can be configured compactly.
[0027]
Further, according to the sensor mounting structure and the measurement display of the present invention provided with the insertion detecting means, a person who performs a blood glucose level test can recognize that the sensor unit has been positioned and fixed. Further, since the insertion detection means reacts by the convex portions on the front surface or the back surface of the sensor unit, it can be recognized that the sensor unit has been properly positioned and fixed without misidentifying the front and back. For this reason, the measurement work by a biosensor can be performed reliably.
[0028]
Further, according to the sensor mounting structure and the measurement display device of the present invention including the engaging member engaged with the sensor unit, the sensor unit is mounted on the sensor mounting structure in a state where the engaging member is engaged with the sensor unit. Thus, the sensor unit can be reliably positioned and fixed. Further, it is possible to prevent the sensor unit from being detached from the sensor mounting structure during the measurement work.
