[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-4As shown, the reagent strip holding and discarding module includes a support 1, a lead screw motor 6, a detection plate 3, and a fixing plate 2. The detection plate 3 is fixed on the support 1. The detection plate 3 has a slot 3a that allows the reagent strip 10 to be shifted in from one end and shifted out from the other side. The detection plate 3 also has a clearance opening 3b, which is connected to the other side of the slot 3a. The lead screw motor 6 is fixed on the detection plate 3 by a mounting piece 4. The fixing plate 2 is connected to the lead screw end of the lead screw motor 6. The lead screw motor 6 is an existing product, and the connection of the fixing plate 2 to the lead screw end of the lead screw motor 6 is also an existing method. The fixing plate 2 has a spring piece 9 for holding the reagent strip 10, and the spring piece 9 is fixed to the fixing plate 2 by screws. Specifically: the spring piece 9 The mounting plate 2 includes a top spring and a side spring. The top spring is fixed to the top pressure plate 2a, and the side spring is fixed to the side ejection plate 2c. The fixing plate 2 includes a top pressure plate 2a, a side pressure plate 2b, and a side ejection plate 2c. The side pressure plate 2b and the side ejection plate 2c are respectively arranged on both sides of the top pressure plate 2a. The fixing plate 2 also includes a connecting plate 2d, which is arranged on the top pressure plate 2a. The connecting plate 2d also has an indicator plate 2e. The mounting plate 4 is also equipped with a photoelectric switch 5 that cooperates with the indicator plate 2e. In this embodiment, the photoelectric switch 5 detects the position of the fixing plate 2 to determine the position of the fixing plate 2. This is a prior art technique. The fixing plate 2 is integrally manufactured. This is a prior art manufacturing method.

[0020] In the initial state, the photoelectric switch 5 detects that the fixed plate 2 is in the zero position. At this time, the lead screw range of the lead screw motor 6 is in the shortest state. The fixed plate 2 and the detection plate 3 are in the position shown in Figure 1. The clearance port 3b of the detection plate 3 is for clearance.

[0021] When the fixing plate 2 is in the zero position, the reagent strip 10 is pushed into the slot 3a. At this time, the two sides of the reagent strip 10 are limited by the inner wall of the other side of the detection plate 3 and the inner surface of the spring sheet 9, respectively, so as to achieve the purpose of tight fixation and ensure that the reagent strip 10 is in the center position of fluorescence detection. At the same time, because the spring sheet 9 is selected, there is a certain amount of elastic space, so that it is not too narrow to be pushed in.

[0022] After the test is completed, the reagent strip 10 is pushed to the innermost side. At this time, the lead screw motor 6 starts to move and drives the fixed plate 2 to move synchronously until the reagent strip 10 is completely removed from the test plate 3.

[0023] A waste hopper 8 with a collection port 8a is detachably installed on the bracket 1. After the waste hopper 8 is installed on the bracket 1, the waste hopper 8 is located on the side of the detection plate 3, so that the reagent strip 10 at the slot 3a can be pushed out horizontally and fall into the waste hopper 8. In this embodiment, the waste hopper 8 is not fixed, but is a pull-out type. It can be filled with waste reagent strip 10 and then pulled out to empty the reagent strip 10.

[0024] The detection plate 3 is also fixed with an introduction piece 7. In this embodiment, when the reagent strip 10 is translatably input into the slot 3a, the introduction piece 7 can play the role of introducing it.

[0025] In summary, when the fixing plate 2 is in the initial position, the side pressure plate 2b closes the opening on one side of the slot 3a, and the reagent strip 10 moves into the slot 3a. The top spring and side spring hold the reagent strip 10 in place, that is, the spring 9 can keep the reagent strip 10 in a fixed state. After the test is completed, the lead screw motor 6 can move the fixing plate 2 towards the waste hopper 8. Due to the action of the side push-out plate 2c, the reagent strip 10 in the slot 3a is pushed outward. At this time, the reagent strip 10 is in a loose state and can automatically fall into the waste hopper 8.

[0026] In this invention, the reagent strip 10 is conveyed into the slot 3a of the detection plate 3. The spring 9 in the fixing plate 2 will firmly press the reagent strip 10 into the slot 3a. After the existing fluorescence detection module completes the detection of the reagent strip 10, the lead screw motor 6 starts and drives the fixing plate 2 to move. The fixing plate 2 will move the reagent strip 10 above the waste hopper 8. The reagent strip 10 falls into the waste hopper 8 due to gravity, thereby realizing the convenient holding and disposal of the reagent strip 10.

[0027] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
