Description

Technical Field

[0001] This utility model relates to the field of biochemical and immunoassay analysis technology, and in particular to a foolproof assembly structure for a sampler and a reagent kit. Background Technology

[0002] A fully automated biochemical and immunoassay analyzer is a device that performs biochemical and immunological tests simultaneously with a single sample injection. Automation is achieved by mounting the reagent kit onto a mounting base, which is then moved to different stations within the analyzer. To be compatible with the analyzer, the reagent kit includes sample chambers and detection chambers.

[0003] For example, Chinese Patent Publication No. CN209535773U discloses a test kit, including a kit body and a reagent card cap. The kit body is provided with a test strip storage section, a detection chamber, a reagent holding section for holding reagents, and a sample chamber. The reagent card cap is configured to cooperate with the kit body. The reagent card cap is provided with a card cap holding position that cooperates with the reagent holding section, a card cap detection position that cooperates with the detection chamber, a sampling placement position, and a sample aspiration placement position. A sampling head assembly is placed on the sampling placement position, and a sample aspiration component is placed on the sample aspiration placement position. The sampling head assembly includes a sampling head body, a conical opening provided on the sampling head body, a sampler communicating with the conical opening, and a handle installed on the sampling head body.

[0004] The sampling head assembly of the aforementioned existing test kits is generally square, resulting in low directional accuracy and making it easy for users to misjudge the orientation during assembly. When the sampling head assembly is assembled incorrectly in the sampling placement position, the following problems can easily occur: 1. Assembly stability issues: The sampling head assembly is not securely attached to the main body of the test kit, and it is easy for the sampling head assembly to detach from the main body; 2. Interruption of the testing process: If the sampling head assembly contains blood samples, detachment will prevent subsequent testing from proceeding normally; 3. Biosafety risks: Blood samples may leak and contaminate the inside of the testing instrument. If the blood sample carries pathogens, it may further cause cross-contamination or user exposure risks.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a foolproof assembly structure for a sampler and a reagent kit.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides a foolproof assembly structure for a sampler and a reagent kit, including a placement seat on the reagent kit and an assembly cover on the sampler. The assembly cover and the placement seat have matching shapes. The shapes of the assembly cover and the placement seat are both set to have a larger size at one end and a smaller size at the other end, so that the assembly cover can only be fitted onto the placement seat in a single orientation.

[0009] By designing both the assembly cap and the placement base to have a shape that is larger at one end and smaller at the other, users can quickly and easily determine the accurate assembly orientation through direct and simple observation. Furthermore, the assembly cap can only be fitted onto the placement base in a single orientation, ensuring that the sampler is installed correctly. In other words, the shape design of the assembly cap and the placement base achieves a dual foolproof effect of visual guidance and shape matching restriction, ensuring that the sampler is installed correctly and effectively avoiding the risk of the sampler falling off the reagent kit due to improper installation.

[0010] It is understood that the shape described above, where one end is larger than the other, can be an isosceles trapezoid, an isosceles triangle, etc. Those skilled in the art can set specific shapes as needed, and this utility model does not impose any limitations.

[0011] According to the above scheme, the assembly cover includes a top plate and an outer plate, with the outer plate surrounding the bottom of the top plate.

[0012] According to the above scheme, the outer wall of the outer plate is provided with longitudinally arranged anti-slip grooves. By providing anti-slip grooves, the friction between the outer plate and fingers is increased, making it easier for the user to hold the outer plate and install the assembly cover on the placement seat.

[0013] According to the above scheme, the assembly cover is detachably fixed to the placement base by a snap-fit ​​mechanism.

[0014] According to the above scheme, the buckling mechanism includes a protrusion and a slot that mates with the protrusion; the protrusion is provided on one of the inner sidewall of the outer plate and the outer sidewall of the placement seat, and the slot is provided on the other.

[0015] By setting a protrusion that engages with a slot, the assembly cover can be detachably fixed on the placement base, and the user can also sense whether the assembly cover is in place.

[0016] According to the above scheme, the sampler is fixed to the bottom of the top plate, and the top plate has a through hole. The upper opening of the sampler is connected to the through hole. The sampling component passes through the through hole in the top plate and is inserted into the sampler to draw up the sample from the sampler.

[0017] According to the above scheme, the upper opening of the sampler is funnel-shaped, wider at the top and narrower at the bottom. This design guides the insertion of the sampling component, making it easier for the component to enter the sampler.

[0018] According to the above scheme, multiple reinforcing ribs are uniformly fixed on the outer wall of the sampler, and these reinforcing ribs are fixedly connected to the top plate. By setting multiple reinforcing ribs, the stability of the connection between the sampler and the top plate is improved.

[0019] According to the above scheme, the reagent kit is provided with a sample suction head holder. The sample suction head holder is used to hold the sample suction components.

[0020] Furthermore, the reagent kit is provided with a reagent chamber, a reaction chamber, and a detection chamber. It is understood that those skilled in the art can set the number of reagent chambers, reaction chambers, and detection chambers according to actual needs. The beneficial effects of this invention are:

[0021] This invention sets both the assembly cap and the placement base to a shape with one end larger than the other, allowing users to quickly and easily determine the accurate assembly direction through direct and simple observation. Furthermore, it ensures that the assembly cap can only be fitted onto the placement base in a single orientation, thus guaranteeing proper installation of the sampler. In other words, the shape design of the assembly cap and placement base achieves a dual foolproof effect of visual guidance and shape matching constraints, ensuring proper installation of the sampler and effectively avoiding the risk of the sampler detaching from the reagent kit due to improper installation.

[0028] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown, this utility model provides a foolproof assembly structure for a sampler and a reagent kit, including a placement seat 11 on the reagent kit 1 and an assembly cover 3 on the sampler 2, wherein the assembly cover 3 and the placement seat 11 have matching shapes.

[0030] Both the mounting cover 3 and the placement seat 11 are designed with one end larger than the other, so that the mounting cover 3 can only be fitted onto the placement seat 11 in a single orientation.

[0031] By setting the shapes of both the assembly cover 3 and the placement base 11 to be large at one end and small at the other, users can quickly determine the accurate assembly direction through direct and simple observation. Moreover, the assembly cover 3 can only be fitted onto the placement base 11 in a single orientation, thus ensuring that the sampler 2 is installed in place. In other words, the shape settings of the assembly cover 3 and the placement base 11 achieve a dual foolproof effect of visual guidance and shape matching restriction, ensuring that the sampler 2 is installed in place and effectively avoiding the risk of the sampler 2 falling off the reagent kit 1 due to improper installation.

[0032] In this embodiment, both the mounting cover 3 and the placement seat 11 are set to be isosceles trapezoids. In some embodiments, those skilled in the art can set other shapes as needed.

[0033] Furthermore, the mounting cover 3 includes a top plate 31 and an outer plate 32, with the outer plate 32 surrounding the bottom of the top plate 31.

[0034] Furthermore, the outer wall of the outer plate 32 is provided with longitudinally arranged anti-slip grooves 321. By providing anti-slip grooves 321, the friction between the outer plate 32 and the fingers is increased, making it easier for the user to hold the outer plate 32 and install the mounting cover 3 on the placement base 11.

[0035] Furthermore, the mounting cover 3 is detachably fixed to the placement base 11 by a snap-fit ​​mechanism.

[0036] Furthermore, the buckling mechanism includes a protrusion 322 and a slot 111 that engages with the protrusion 322; the protrusion 322 is provided on the inner sidewall of the outer peripheral plate 32, and the slot 111 is provided on the outer sidewall of the placement seat 11.

[0037] By setting a protrusion to cooperate with the slot, the assembly cover 3 can be detachably fixed on the placement base 11, and the user can also feel whether the assembly cover 3 is placed in place.

[0038] Furthermore, the sampler 2 is fixed to the bottom of the top plate 31, and the top plate 31 has a through hole 311. The upper opening 21 of the sampler 2 is connected to the through hole 311. The sampling component passes through the through hole 311 on the top plate 31 and is inserted into the sampler 2 to draw the sample from the sampler 2.

[0039] Furthermore, the upper opening 21 of the sampler 2 is funnel-shaped, wider at the top and narrower at the bottom. This design allows the upper opening 21 to guide the insertion of the sampling component, making it easier for the sampling component to enter the sampler 2.

[0040] Furthermore, a plurality of reinforcing ribs 22 are uniformly fixed on the outer wall of the sampler 2, and the plurality of reinforcing ribs 22 are fixedly connected to the top plate 31. By setting a plurality of reinforcing ribs 22, the stability of the connection between the sampler 2 and the top plate 31 is improved.

[0041] Furthermore, the reagent kit 1 has a protruding sample suction head holder 12. The sample suction head holder 12 is used to hold the sample suction components.

[0042] Furthermore, the reagent kit 1 is provided with a reagent chamber 13, a reaction chamber 14, and a detection chamber 15.

[0043] When using the foolproof assembly structure of the sampler and reagent kit described in this utility model, hold the outer plate 32 of the assembly cover 3 and add the blood sample to be tested into the sampler 2 through the through hole 311; put the assembly cover 3 on the placement seat 11 from top to bottom in the only accurate installation direction, and when the protrusion 322 is felt to be inserted into the slot 111, it means that the assembly cover 3 and the sampler 2 have been placed in place; then place the suction component on the suction head placement rack 12, and install the reagent kit 1 on the corresponding fixed seat of the detector to start automatic detection.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
