According to another embodiment of the present invention, the two connecting ends 422 are elastically supported against the inner side wall of the receiving box 20, whereby the elastic piece 42 can be fixed in the receiving box 20 and elastically pressed against the outer side of the pushing member 412. Thereby, the space for setting the elastic piece 42 is reduced, and a better elastic restoring force is provided. As shown in FIG. 6, when the biochemical value detector 1 of the present invention has not been connected to the test strip, the slide member 41 is closer to the opening 23 at this time, and the elastic piece 42 is in a state of natural relaxation, and the resisting section 421 of the elastic piece 42 is lightly touched. The pushing member 412 of the slider 41 and the contact portion 431 of the ejecting button 43 do not contact the contact portion 413 of the slider 41.

As shown in FIG. 7, in the process of detecting that the test piece 90 is inserted into the test piece connector 33 from the opening 23, the slide member 41 is horizontally moved along the guide groove 331 by being pushed by the detected test piece 90 until the contact portion 413 of the slide member 41. The contact portion 431 of the eject button 43 is brought into contact with and the contact portion 413 is stopped against the retaining wall 44. At this time, the abutting portion 421 of the elastic piece 42 is deformed in the horizontal direction away from the opening 23 by being pressed by the pushing member 412 of the sliding member 41, and the detecting test piece 90 also completes the connection with the test piece connector 33, in this state. The specific actions as described above can be performed. In one embodiment, the user simply presses the cover 10 above the free zone 22 to trigger the detection body 30 to be triggered by the cover 10 to activate the sample test on the test strip 90. In another embodiment, the test strip 90 is connected to the test strip connector 33 to automatically detect the sample specimen on the test strip 90.

It should be noted that when the elastic piece 42 is pushed by the sliding member 41, the two connecting ends 422 of the elastic piece 42 are not fixed but slide along the inner wall of the receiving box 20 in the slot 262. According to this, the abutting section 421 of the elastic piece 42 generates a large deformation, thereby providing a greater elastic restoring force.

As shown in FIG. 8, after the sample detection is completed, the user can push the ejection button 43, thereby releasing the interference state between the contact portion 413 of the slider 41 and the contact portion 431 of the ejection button 43, The sliding force of the slider 41 is pushed along the guide groove 331 by the restoring force of the abutting portion 421, and the detecting test piece 90 is also pushed out from the test piece connector 33, and finally the detecting test piece 90 is automatically separated from the detecting body 30.

Specifically, in the embodiment, when the eject button 43 is pressed by an external force, the contact portion 431 pushes down the contact portion 413 and disengages the contact portion 413 from the latch of the barrier wall 44. The slider 41 is elastically pushed by the elastic piece 42 after the contact portion 413 is disengaged from the click. Subsequently, the elastic restoring force of the elastic piece 42 pushes the sliding member 41 forward. At this time, the test piece 90 in the test piece connector 33 is also pushed forward by the sliding portion 411 of the sliding member 41 while being forward. It then leaves the opening 23. Accordingly, the biochemical value detector 1 of the present embodiment achieves the purpose of ejecting and ejecting the test strip 70 by the setting of the ejecting device 40.

In addition, in some embodiments, since the ejecting button is integrally formed with the accommodating case as described above, and the cover body and the accommodating case are properly combined without a gap, only the opening of the biochemical value detector can be substantially in communication with the outside, so that We can effectively control impurities such as dust into the biochemical value detector, prolong the service life of the biochemical value detector, and reduce the failure frequency of the biochemical value detector.

It should be noted that the above is only an embodiment, and is not limited to the embodiment. Therefore, those who do not depart from the basic structure of the present invention should be bound by the scope of the patent, and the scope of the patent application shall prevail.
