Description

Technical Field

[0001] The utility model relates to the technical field of fluorescent immunoassay analyzers, and in particular to a reagent card positioning device for a fluorescent immunoassay analyzer. Background Art

[0002] Fluorescent immunoassay analyzer is a kind of instrument commonly used in fields such as biomedical research and drug development. It can perform non-invasive detection of biological molecules to obtain results quickly. Fluorescent immunoassay analyzer generally consists of two parts: detector and reagent card. When in use, the biological reagent is dropped into the reagent card, and then the end of the reagent card carrying the biological reagent is inserted into the detector. Then the detector is used to detect the molecules in the biological reagent in the reagent card to obtain the test results.

[0003] When the reagent card in a traditional fluorescent immunoassay analyzer is inserted into the detector, it is generally inserted directly for simple positioning. Although this card connection method is simple and convenient, the positioning restriction force of the detector on the reagent card is relatively small, and the frequent insertion and removal of the reagent card can easily cause greater wear on the detector's socket, resulting in the reagent card becoming loose when inserted later, thereby affecting subsequent test results. Utility Model Content

[0004] The utility model aims to provide a reagent card positioning device for a fluorescent immunoassay analyzer, so as to solve the problem that the fluorescent immunoassay analyzer in the prior art has little positioning restriction on the reagent card, which causes the reagent card to be easily loosened, thereby affecting the test result.

[0005] The utility model provides the following technical solution: a reagent card positioning device for a fluorescent immunoassay analyzer, comprising a detector, a reagent card is arranged on the outside of the detector, and card slots are provided on both sides of an end of the reagent card close to the detector, a clamping component is fixedly connected inside the end of the detector close to the reagent card, and a separation component is fixedly connected to the end of the clamping component away from the reagent card.

[0006] As a preferred embodiment of the above technical solution, a pushing component is fixedly connected inside the middle end of the detector, and elastic components are fixedly connected to the outer sides of both ends of the pushing component.

[0007] As a preferred embodiment of the above technical solution, the positioning assembly includes a card block fixedly inserted into the interior of one end of the detector close to the reagent card, and a first spring is fixedly connected to the middle of one end of the card block inserted in the detector, and the end of the first spring away from the card block is fixedly connected to the inner side of the detector.

[0008] As a preferred embodiment of the above technical solution, the separation component includes a separation block arranged on a side of the card block away from the reagent card, and a plug rod is fixedly connected to a side of the separation block close to the card block, an end of the plug rod away from the separation block is inserted in the card block, and a second spring is fixedly connected to the side of the plug rod away from the separation block, an end of the second spring away from the plug rod is fixedly connected to the inner side of the card block, and a first telescopic rod is fixedly connected to the middle part of one end of the separation block inserted into the inner side of the detector, a slider is fixedly connected to the side of the first telescopic rod away from the separation block, and an end of the slider away from the first telescopic rod is inserted and slid in the detector.

[0009] As a preferred embodiment of the above technical solution, the pushing component includes a pushing plate inserted into the inner side of the middle end of the detector, and a rubber pad is fixedly connected to the side of the pushing plate close to the reagent card.

[0010] As a preferred embodiment of the above technical solution, the elastic component includes a third spring fixedly connected to the middle end of the side of the push plate away from the reagent card, and the end of the third spring away from the push plate is fixedly connected to the inner side of the detector, and the two ends of the side of the push plate away from the reagent card are fixedly connected to the second telescopic rod, and the end of the second telescopic rod away from the push plate is inserted and fixed in the detector.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The reagent card positioning device of the fluorescent immunoassay analyzer has the advantages that when the reagent card needs to be inserted into the detector to detect the biological reagent, the end of the reagent card close to the card slot is first inserted into the detector. During the insertion process, the reagent card squeezes the clamping components on both sides, and the clamping components are squeezed while driving the separation components to move. When the detector carries the card slot to the clamping component, the clamping component pops out and is inserted into the card slot to position the detector. After the detection is completed, the detector is pushed again to continue to be inserted into the detector to squeeze the separation component. After the separation component is squeezed, it drives the clamping component to move and pull out of the card slot. Then the detector drives the separation component to move and fit with the clamping component. At this time, the reagent card can be pulled out of the detector by pulling it, so that when the reagent card is inserted into the detector for detection, the detector can use the clamping component to quickly clamp and position the reagent card, thereby improving the stability of the detector after insertion, and facilitating subsequent detection.

[0013] The reagent card positioning device of the fluorescent immunoassay analyzer, when the reagent card needs to be pulled out, pushes the reagent card to squeeze the separation component, and the reagent card squeezes the pushing component synchronously, and the pushing component is squeezed and then squeezes the elastic component, and the elastic potential energy of the elastic component increases after being squeezed, and when the positioning component is pulled out of the card slot, the elastic component pushes the pushing component to push the reagent card out of the detector with the assistance of the separation component, so that when the reagent card needs to be taken out after the test, it can be taken out more simply and quickly, thereby improving the convenience of use.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a reagent card positioning device for a fluorescent immunoassay analyzer, comprising a detector 1, a reagent card 11 is arranged on the outside of the detector 1, and card slots 12 are provided on both sides of one end of the reagent card 11 close to the detector 1, a card position component is fixedly connected inside the end of the detector 1 close to the reagent card 11, and a separation component is fixedly connected to the end of the card position component away from the reagent card 11. When the reagent card 11 needs to be inserted into the detector 1 to detect the biological reagent, the end of the reagent card 11 close to the card slot 12 is first inserted into the detector 1. During the insertion process, the reagent card 11 squeezes the card position components on both sides, and the separation component is driven to move while the card position component is squeezed. When the detector 1 carrying the card slot 12 arrives at the locking component, the locking component pops out and is inserted into the card slot 12 to position the detector 1. After the detection is completed, the detector 1 is pushed again to allow the detector 1 to continue to be inserted into the detector 1 to squeeze the separation component. After the separation component is squeezed, it drives the locking component to move and pull out of the card slot 12. Then the detector 1 drives the separation component to move and fit with the locking component. At this time, the reagent card 11 can be pulled out of the detector 1, so that when the reagent card 11 is inserted into the detector 1 for detection, the detector 1 can use the locking component to quickly lock and position the reagent card 11, thereby improving the stability of the detector 1 after insertion, and facilitating subsequent detection.

[0021] like Figure 2 and Figure 4 As shown, a pushing component is fixedly connected to the inside of the middle end of the detector 1, and elastic components are fixedly connected to the outer sides of the two ends of the pushing component. When the reagent card 11 needs to be pulled out, the reagent card 11 is pushed to squeeze the separation component, and the reagent card 11 simultaneously squeezes the pushing component. After the pushing component is squeezed, the elastic component is squeezed. After the elastic component is squeezed, the elastic potential energy increases. When the positioning component is pulled out of the card slot 12, the elastic component pushes the pushing component to push the reagent card 11 out of the detector 1 with the assistance of the separation component, so that when the reagent card 11 needs to be taken out after the test, it can be taken out more simply and quickly, thereby improving the convenience of use.

[0022] like Figure 2 and Figure 3 As shown, the locking assembly includes a locking block 2 fixedly inserted inside one end of the detector 1 close to the reagent card 11, and a first spring 21 is fixedly connected to the middle part of one end of the locking block 2 inserted in the detector 1, and the end of the first spring 21 away from the locking block 2 is fixedly connected to the inner side of the detector 1. When the reagent card 11 is inserted into the detector 1 and the locking block 2 is squeezed, the locking block 2 is squeezed and inserted into the detector 1 to compress the first spring 21, and then the elastic potential energy of the first spring 21 is used to push the locking block 2 in the reverse direction, so that the locking block 2 is inserted into the card slot 12 to lock and fix the reagent card 11, which can improve the stability of the reagent card 11 after insertion, thereby facilitating subsequent detection.

[0023] like Figure 2 and Figure 3 As shown, the separation component includes a separation block 3 arranged on a side of the card block 2 away from the reagent card 11, and a plug rod 31 is fixedly connected to a side of the separation block 3 close to the card block 2, and an end of the plug rod 31 away from the separation block 3 is inserted in the card block 2, and a second spring 32 is fixedly connected to the side of the plug rod 31 away from the separation block 3, and an end of the second spring 32 away from the plug rod 31 is fixedly connected to the inner side of the card block 2, and a first telescopic rod 33 is fixedly connected to the middle of one end of the separation block 3 inserted in the inner side of the detector 1, and a slider 34 is fixedly connected to the side of the first telescopic rod 33 away from the separation block 3, and an end of the slider 34 away from the first telescopic rod 33 is inserted and slidable in the detector 1 When the reagent card 11 needs to be pulled out later, the reagent card 11 is continued to be pushed so that the reagent card 11 squeezes the separation block 3. After the separation block 3 is squeezed, the card block 2 is driven to move and be inserted into the detector 1 through the insertion rod 31 under the limit of the first telescopic rod 33. After the card block 2 is pulled out of the card slot 12, the reagent card 11 is pulled to drive the separation block 3 to move with the assistance of the first telescopic rod 33 and the slider 34. After the first telescopic rod 33 moves, the insertion rod 31 is pushed to be inserted into the card block 2 to compress the second spring 32. When the separation block 3 and the card block 2 are in contact with each other on the opposite side, the reagent card 11 is pulled out of the detector 1, so that it can be pulled out quickly, thereby improving the convenience during use.

[0024] like Figure 2 and Figure 4 As shown, the pushing component includes a push plate 4 inserted on the inner side of the middle end of the detector 1, and a rubber pad 41 is fixedly connected to the side of the push plate 4 close to the reagent card 11. After the reagent card 11 is pushed, the reagent card 11 squeezes the rubber pad 41 and the push plate 4, so that the push plate 4 can push the elastic component, and then use the elastic potential energy of the elastic component to push the push plate 4 and the rubber pad 41 in the opposite direction, so that the push plate 4 and the rubber pad 41 can quickly push the reagent card 11 out of the detector 1, making it more convenient to take out the reagent card 11.

[0025] like Figure 2 and Figure 4 As shown, the elastic component includes a third spring 5 fixedly connected to the middle end of the side of the push plate 4 away from the reagent card 11, and the end of the third spring 5 away from the push plate 4 is fixedly connected to the inner side of the detector 1, and the two ends of the side of the push plate 4 away from the reagent card 11 are fixedly connected with second telescopic rods 51, and the end of the second telescopic rod 51 away from the push plate 4 is inserted and fixed in the detector 1. When the push plate 4 is pushed, the third spring 5 is squeezed under the limit of the second telescopic rod 51. After the third spring 5 is squeezed, the elastic potential energy of the third spring 5 increases, so that the elastic potential energy of the third spring 5 is used to push the push plate 4 and the rubber pad 41 in the reverse direction, so that the push plate 4 and the rubber pad 41 push the reagent card 11 to pop out quickly, effectively improving the convenience of taking out the reagent card 11.

[0026] Working principle: When the fluorescent immunoassay analyzer is needed to detect biological reagents, the biological reagent is dripped into the reagent hole at the upper end of the reagent card 11, and then the end of the reagent card 11 near the card slot 12 is inserted into the detector 1. During the insertion of the reagent card 11, the card blocks 2 on both sides are squeezed. After the card block 2 is squeezed, it is inserted into the detector 1 to compress the first spring 21. When the reagent card 11 drives the card slot 12 to move to the end of the card block 2, the first spring 21 pushes the card block 2 in the opposite direction to pop out, so that the card block 2 is inserted into the card slot 12 to limit the position of the reagent card 11. Then, the detector 1 is used to detect the biological reagent in the reagent hole of the reagent card 11. When the reagent card 11 needs to be taken out after the test, the reagent card 11 is pushed again to allow the reagent card 11 to move and squeeze the separation block 3. After the separation block 3 is squeezed, it moves between the first telescopic rod 33 and the insertion rod 3. 1, the card block 2 is inserted into the detector 1 with the assistance of the first telescopic rod 33 and the slider 34, compressing the first spring 32, so that the separation block 3 and the card block 2 are fitted on the opposite side. At this time, the reagent card 11 is pushed by the push plate 4 and the rubber pad 41 to quickly pop out a part of it and separate it from the card block 2. Finally, the reagent card 11 is pulled out of the detector 1.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
