The width of the groove 1-20 is adapted to the width of the arm of the V-shaped spring piece 1-15 in the groove 1-20, so as to prevent the arm from sliding left and right or shaking during use, thereby affecting the stability of the hook body.

[0041] Furthermore, the support arm connecting the V-shaped spring piece 1-15 and the hook seat 1-14 is provided with an extension part 1-18 extending along its length direction, and the extension part includes two parts, which are symmetrically arranged on both sides of the support arm. The contact area between the support arm and the hook seat 1-14 is increased, the stability is improved, and the strength of the support arm is improved.

[0042] For further information, see Figure 8 The card ejection mechanism 5 includes a card ejection push plate 5-5, a guide mechanism and a reset mechanism. The card feeding mechanism 1 drives the reagent card 9 to push the card ejection push plate 5-5 to reciprocate along the guide mechanism in the horizontal direction to eject the reagent card 9 on the card throwing position 3 to realize card ejection. After the card is ejected, the reset mechanism drives the card ejection push plate 5-5 to reset; the guide mechanism guides the movement direction of the card ejection push plate 5-5.

[0043] Furthermore, the card ejection mechanism 5 also includes a bracket 5-1, and the card ejection push plate 5-5 is connected to one side of the bracket 5-1 through a connecting rod 5-6. The end of the bracket 5-1 located at one end of the card feeding mechanism 1 is provided with an extension portion 5-2 extending vertically downward; the guide mechanism includes a guide shaft 5-3 and two guide shaft bracket units 5-4. Preferably, there are two guide shafts 5-3, and the two guide shafts 5-3 are arranged in parallel. The two ends of the two guide shafts 5-3 are respectively connected to the two guide shaft bracket units 5-4, and the bracket 5-1 is passed through the guide shaft 5-3. The card feeding mechanism 1 drives the reagent card 9 to resist the extension portion 5-2 to push the bracket 5-1 to reciprocate in the horizontal direction along the guide shaft 5-3.

[0044] Furthermore, the reset mechanism includes an elastic component (not shown in the figure), which is preferably a spring. The spring is sleeved on the guide shaft 5-3, and one end of the spring is in conflict with the guide shaft bracket unit 5-4 located on one side of the card ejection push plate 5-5, and the other end of the spring is in conflict with the bracket 5-1 located on one side of the card ejection push plate 5-5.

[0045] See also Figures 1 to 4 The card slots are arranged in the card inlet 8, the card inlet units 1-7 and the incubation tank 7, and the card slots are parallel to each other. The card slot structure is described in detail by taking the card slot in the card inlet unit 1-7 as an example, see Figure 3 and Figure 4 The card slot includes a bottom plate 1-9, an end of the bottom plate 1-9 is provided with a long strip notch 1-8, a clamping member 1-3 is provided above the bottom plate 1-9, and the clamping member 1-3 is an elastic member. A card slot for clamping the reagent card 9 is formed between the clamping member 1-3 and the bottom plate 1-9. The hook card slide rail 1-6 is fixed to the bottom of the bottom plate 1-9 in the card feeding unit 1-7 and is provided corresponding to the long strip notch 1-8. When the hook card device moves to the bottom of the card feeding unit 1-7, the top of the hook body 1-12 is located in the long strip notch 1-8. The long strip notch 1-8 allows the hook body 1-12 to enter the card slot and match with the groove 9-1 on the bottom surface 9-2 of the reagent card 9, so as to hook up the reagent card 9 and drive it to move. Therefore, the lengths of the long strip notches in the bottom plates of the card feeding unit 1-7, the card feeding port 8, and the incubation tank 7 are not exactly the same. The detection module 2 is provided with a placement slot for placing the reagent card 9. The difference between the placement slot and the card slot is that there is no card connector on the top. Due to the diagnostic analyzer of the present invention, the reagent card 9 is placed in the placement slot of the detection module 2 for detection, and the reagent card 9 in the placement slot is directly pushed out to realize card ejection after the detection, so the placement slot is the card ejection position.

[0046] During operation, the reagent card 9 is inserted into the card inlet 8, and the control driving mechanism 4a drives the card inlet mechanism 1 to move along the slide rail 4 toward the card inlet 8 until the card slot in the card inlet 8 and the card slot in the card inlet unit 1-7 are in the same straight line; the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body to move toward the first end along the hook card slide rail 1-6. When the hook body enters from below the reagent card 9 in the card inlet 8, the reagent card 9 presses the hook body downward, and when the hook body moves to the groove 9-1 on the bottom surface 9-2 of the reagent card 9, it bounces upward and is engaged in the groove 9-1, hooking the reagent card; the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body and the reagent card 9 to move along the hook card slide rail 1-6 toward the second end until the reagent card 9 is brought into the card slot in the card inlet unit 1-7.

After the reagent card 9 is stuck in the card slot of the incubation tank 7, the end of the reagent card 9 away from the card feeding unit 1-7 is against the side wall of the incubation tank 7; continue to control the driving device 1-1 to drive The movable hook card seat 1-14 drives the hook body to move along the hook card slide rail 1-6 toward the first end, and the hook body disengages from the groove 9-1 of the reagent card 9; the control driving mechanism 4a drives the card feeding mechanism 1 to move along the slide rail 4, and the hook body deviates from the groove 9-1 on the bottom surface 9-2 of the reagent card 9 in the card slot of the incubation tank 7. At the same time, the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body to move along the hook card slide rail 1-6 toward the second end, and the control driving mechanism 4a drives the card feeding mechanism 1 to move along the slide rail 4 toward the card inlet 8. Repeat the above steps to send the reagent card at the card inlet 8 into the incubation tank 7.

[0048] After the reagent card in the incubation tank 7 is incubated at a constant temperature for the incubation time, the reagent card 9 in the incubation tank 7 needs to be transferred to the detection module 2 for detection.

[0049] The control driving mechanism 4a drives the card feeding mechanism 1 to move along the slide rail 4 toward the incubation module 4 until the card slot in the card feeding unit 1-7 and the card slot in the incubation tank 7 are in the same straight line, and the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body to move along the hook card slide rail 1-6 toward the first end. When the hook body enters from below the reagent card 9 in the incubation tank 7, the reagent card 9 presses the hook body downward, and when the hook body moves to the groove 9-1 on the bottom surface 9-2 of the reagent card 9, it bounces upward and is engaged in the groove 9-1 to hook the reagent card; the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body and the reagent card 9 to move along the hook card slide rail 1-6 toward the second end until the reagent card 9 is brought into the card slot in the card feeding unit 1-7. The control driving mechanism 4a drives the card feeding mechanism 1 to move along the slide rail 4 toward the detection module 2 until the card slot in the card feeding unit 1-7 and the placement slot in the detection module 2 are in the same straight line, and the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body and the reagent card 9 in the card slot in the card feeding unit 1-7 to move along the hook card slide rail 1-6 toward the first end, and bring the reagent card 9 into the placement slot of the detection module 2. After the reagent card 9 enters the placement slot, the end of the reagent card 9 away from the card feeding unit 1-7 rests on the side wall of the placement slot; the control driving device 1-1 continues to drive the hook card seat 1-14 to drive the hook body to move along the hook card slide rail 1-6 toward the first end, and the hook body disengages from the groove 9-1 of the reagent card 9; the control driving mechanism 4a drives the card feeding mechanism 1 to move along the slide rail 4, and the hook body deviates from the groove 9-1 of the bottom surface 9-2 of the reagent card 9 in the placement slot. At the same time, the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body to move along the hook card slide rail 1-6 toward the second end.

[0050] The detection module 2 detects the reagent card 9 in its placement slot, and at the same time uses the above-mentioned method to bring the reagent card 9 in the incubation tank 7 into the card slot in the card input unit 1-7.

[0051] After the detection module 2 has finished the detection, the control driving device 1-1 drives the hook card seat 1-14 to drive the hook body and the reagent card 9 in the card feeding unit 1-7 to move along the hook card slide rail 1-6 toward the first end, and at the same time controls the driving mechanism 4a to drive the card feeding mechanism 1 to move along the slide rail 4, so that one side of the reagent card 9 abuts against the side of the extension part 5-2 away from the placement slot 3; controls the driving mechanism 4a to drive the card feeding mechanism 1 to move along the slide rail 4 toward the placement slot 3, and pushes the bracket 5-1 and the card ejection push plate 5-5 to move in the horizontal direction and push them out of the placement slot 3, at this time, the spring on the guide shaft 5-3 is compressed; after the reagent card 9 on the placement slot 3 is pushed out, the control drive device 1-1 drives the hook card seat 1-14 to drive the hook body and the reagent card 9 to move toward the second end along the hook card slide rail 1-6 to bring the reagent card 9 into the card slot in the card input unit 1-7, and after the reagent card 9 leaves the extension part 5-2, the bracket 5-1 is reset to the standby position under the action of the spring; the above-mentioned method is used to send the reagent card 9 in the card input unit 1-7 to the detection module 2 for detection.
