Description

Technical Field

[0001] This utility model relates to the field of medical test kit technology, and in particular to a tandem thrombin assay kit. Background Technology

[0002] In the determination of thrombin time, thrombin assay kits are usually used to hold the blood samples to be tested. In order to improve the efficiency of taking the assay kits out and putting them in the test chamber, the assay kits are often designed in batches in series.

[0003] Most existing tandem structures of reagent kits rely on interference fits between their assembly and connection components to maintain the overall assembly and usage state, ensuring the kit remains stable in the tandem configuration. However, most assembly and connection components lack structures to temporarily offset the frictional positioning forces generated by the interference fits. This means that frictional positioning forces must be overcome when assembling or disassembling reagent kits. When the frictional positioning forces are too large due to manufacturing errors in the assembly and connection components, the assembly and disassembly operations become strenuous and laborious, thus reducing the convenience of the assembly and disassembly operations. Utility Model Content

[0004] In view of this, the present invention provides a tandem thrombin assay kit to solve the problem that the assembly and disassembly of the kit may be stuck and laborious, thereby reducing the convenience of the assembly and disassembly operation.

[0005] The technical solution proposed by this utility model is: a tandem thrombin assay kit, specifically including a kit body, wherein four short connecting shafts are symmetrically fixed to one end of the kit body;

[0006] The first end of the four connecting short shafts is fixedly connected to a series assembly. The series assembly is integrally formed by two symmetrically distributed U-shaped fittings, a row of arc-shaped connecting plates between the two U-shaped fittings, and a row of vertical force transmission plates between the row of arc-shaped connecting plates. A T-shaped groove is formed between the two U-shaped fittings. The other end of the reagent kit body is integrally formed with a T-shaped connector. The T-shaped connector is slidably assembled and fixedly connected to the series assembly through the T-shaped groove. The two vertical sidewalls of the T-shaped connector are tightly fitted with the two vertical inner walls of the T-shaped groove. Both the arc-shaped connecting plates and the connecting short shafts have a certain elastic deformation performance.

[0007] Furthermore, a blood dripping groove is provided through the middle of the top plate of the reagent kit body, and a sealing plug is installed on the blood dripping groove.

[0008] Furthermore, the sealing plug is composed of a cover plate, a pull-up head and a plug integrally formed at the upper and lower ends of the cover plate, and a rubber sealing ring fixedly fitted on the plug.

[0009] Furthermore, the insert block is inserted into the blood drip groove.

[0010] Furthermore, the shape of the rubber sealing ring is adapted to the shape of the blood dripping groove.

[0011] Furthermore, the outer side of the rubber sealing ring is pressed against and in contact with the inner wall of the blood dripping groove.

[0012] Furthermore, the cross-section of the lifting head is T-shaped.

[0013] The tandem thrombin assay kit provided by this utility model has the following beneficial effects:

[0014] 1. The series components and T-shaped connectors are assembled and connected in series. A row of arc-shaped connecting plates and a row of vertical force transmission plates together form a mechanism for temporarily releasing the positioning force. Through this mechanism, the positioning force can be temporarily released when assembling and disassembling the reagent kit body, avoiding the need to overcome the positioning force when assembling and disassembling the reagent kit body. This prevents the assembly and disassembly operations from being stuck and laborious when the positioning force is too large due to the manufacturing error of the assembly and connecting components, and helps to improve the convenience of assembly and disassembly operations.

[0015] Second, since the connecting short shafts have a certain elastic deformation performance, when a row of arc-shaped connecting plates is pressed down and expanded, the four connecting short shafts can be bent and deformed by the push driven by the two U-shaped fittings. The bending and deformation of the four connecting short shafts can provide displacement margin for the row of arc-shaped connecting plates to drive the back sliding of the two U-shaped fittings, ensuring that the function of temporarily releasing the positioning force is implemented normally and effectively.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please refer to Figures 1 to 6 Example 1:

[0031] This embodiment proposes a tandem thrombin assay kit, including a kit body 1, with four short axes 101 symmetrically fixed to one end of the kit body 1.

[0032] The first end of the four connecting short shafts 101 is fixedly connected to a series assembly 3. The series assembly 3 is integrally formed by two symmetrically distributed U-shaped fittings 301, a row of arc-shaped connecting plates 302 disposed between the two U-shaped fittings 301, and a row of vertical force transmission plates 303 disposed between the row of arc-shaped connecting plates 302. A T-shaped groove is formed between the two U-shaped fittings 301. The other end of the reagent kit body 1 is integrally formed with a T-shaped connector 102. The T-shaped connector 102 is slidably assembled and fixedly connected to the series assembly 3 through the T-shaped groove. The two vertical sidewalls 1021 of the T-shaped connector 102 are tightly fitted with the two vertical inner walls 304 of the T-shaped groove. Both the arc-shaped connecting plates 302 and the connecting short shafts 101 have certain elastic deformation properties.

[0033] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0034] A blood dripping groove 103 is provided through the middle of the top plate of the reagent kit body 1. A sealing plug 2 is inserted into the blood dripping groove 103. The sealing plug 2 is composed of a cover plate 201, a pull head 202 integrally formed at the upper and lower ends of the cover plate 201 and an insert block 204, and a rubber sealing ring 203 fixedly fitted on the insert block 204.

[0035] Preferably, the insert 204 is inserted into the blood dripping groove 103.

[0036] Preferably, the shape of the rubber sealing ring 203 is adapted to the shape of the blood dripping groove 103.

[0037] Preferably, the outer side of the rubber sealing ring 203 is pressed against the inner wall of the blood dripping groove 103.

[0038] Preferably, the cross-section of the lifting head 202 is T-shaped.

[0039] The following section provides a detailed explanation of the specific details, implementation steps, functions and interrelationships of the above features, and their roles in achieving this technical solution:

[0040] The sealing cap 2 is used to seal the blood infusion tank 103. When the series assembly 3 is slidably connected to the T-shaped connector 102, the reagent kit body 1 can be connected in series. When the series assembly 3 is slidably separated from the T-shaped connector 102, the connected reagent kit body 1 can be disassembled into separate independent parts. If the thrombin time of the blood sample in a certain part of the reagent kit body 1 fails to meet the requirements, it may be necessary to disassemble the reagent kit body 1 and further test the blood sample to analyze the cause of the failure of the thrombin time test.

[0041] The series assembly 3 and the T-shaped connector 102 form a series structure of the reagent kit body 1. Through the frictional resistance generated by the tight interference fit between the vertical sidewall 1021 and the vertical inner wall 304, the series assembly 3 and the T-shaped connector 102 are positioned together, maintaining the overall assembly in a connected state and stably keeping the reagent kit body 1 in a series-assembled state. Because the arc-shaped connecting plate 302 has a certain elastic deformation performance, and a row of vertical force transmission plates 303 can synchronously transmit the downward pressure applied to the top arc-shaped connecting plate 302 to all arc-shaped connecting plates 302, when the top arc-shaped connecting plate 302 is pressed downwards, its arch height can be reduced. As its arch height decreases, its arch curvature decreases accordingly, and its two ends expand outwards and shift. When the two ends of the connecting plate 302 expand and shift outward, they can drive the two U-shaped fittings 301 to slide in opposite directions, so that the vertical side wall 1021 and the vertical inner wall 304 are temporarily separated, temporarily releasing the positioning force generated by frictional resistance that fixes the reagent kit body 1 in the series assembly state; the series assembly 3 and the T-shaped connector 102 are a series assembly connection assembly, and a row of arc-shaped connecting plates 302 and a row of vertical force transmission plates 303 together form a mechanism for temporarily releasing the positioning force. Through this mechanism, the positioning force can be temporarily released when assembling and disassembling the reagent kit body 1, avoiding the need to overcome the positioning force when assembling and disassembling the reagent kit body 1. This prevents the assembly and disassembly operation of the reagent kit body 1 from being stuck and laborious when the positioning force is too large due to the manufacturing error of the assembly connection assembly, and helps to improve the convenience of the assembly and disassembly operation.

[0042] Because the connecting short shaft 101 has a certain elastic deformation performance, when the row of arc-shaped connecting plates 302 is pressed down and expanded, the four connecting short shafts 101 can be bent and deformed by the push of the two U-shaped fittings 301. The bending deformation of the four connecting short shafts 101 can provide displacement margin for the row of arc-shaped connecting plates 302 to expand and drive the two U-shaped fittings 301 to slide backward, ensuring that the function of temporarily releasing the positioning force is implemented normally and effectively.

[0043] The working principle of this embodiment is as follows: In use, a blood sample collected from a vein is injected into the reagent kit body 1 through the blood infusion tank 103. Then, the blood infusion tank 103 is sealed by the sealing cap 2 to prevent the blood sample from leaking out of the blood infusion tank 103. Next, multiple reagent kit bodies 1 containing the blood samples to be tested are connected in series and these series-connected reagent kit bodies 1 are transferred in batches to a constant temperature and humidity test chamber to start the thrombin time measurement in the blood sample. After waiting for the standard measurement time to be reached, the reagent kit body 1 is taken out and the blood sample inside is observed to see if it has coagulated. If it has coagulated, the thrombin time measurement is considered qualified; otherwise, it is unqualified. Thus, the time measurement of thrombin by the reagent kit is completed.
