The operation side 10 is an upper surface of a platform of the detecting unit in the embodiment, and a concave detecting groove 11 is formed on the upper surface; the supporting side 20 may be the bottom of the detection slot 11, or the outer edge of the detection unit platform, i.e. the bottom of the detection unit platform, for supporting. The height difference between the operation side 10 and the support side 20 is at least greater than the depth dimension of the detection slot 11.

In this embodiment, the detection groove 11 and the receiving position 12 are both provided with one, which is a single person and is suitable for single person detection. In other embodiments, the detection groove 11 is provided in plurality, the receiving position 12 is correspondingly provided in plurality, and multiple users can be detected, such as home detection.

As shown in fig. 1 to 4, the inner surface of the detection groove 11 is provided with a convex portion 111. When a sample is eluted, the sample is directly soaked in eluent, the elution effect is not ideal, and the sampler 30 is scraped on the convex part 111 through the arrangement of the convex part 111, so that the sample is scraped, and the elution effect is obviously improved.

Specifically, the wall of the detection groove 11 protrudes inward to form the protrusion 111. The protrusions 111 are provided on the bottom and/or the side walls of the detection tank 11. In this embodiment, the protrusion 111 is disposed on the sidewall of the detection slot 11, and by swinging to move up and down, the bottom and the side of the sampler 30 can scrape and rub the protrusion 111.

As shown in fig. 4 to 6, the detection groove 11 includes a step, so that the detection groove 11 forms two layers, the opening of the first layer is larger than the opening of the second layer, and the lowest point of the first layer is connected to the edge of the opening of the second layer. The opening of the first layer is large, so that the eluent can be poured conveniently when poured, the lowest point of the first layer is connected with the opening of the second layer, the eluent can flow into the second layer along the gravity, the second layer is used for collecting the eluent at the moment, the function of a funnel is formed, and the bulge part 111 is also arranged on the second layer. Of course, two layers are adopted here, and three layers or even more layers can be arranged on other alternatives.

As shown in fig. 4 and 5, the receiving position 12 includes a receiving plane 121, and the receiving plane 121 is disposed at an angle of 0 to 80 degrees with respect to the upper surface of the operation side 10. The receiving plane 121 or an extension line thereof extends below the detection slot 11. The bearing plane 121 is used for placing the test paper 40, and the test paper 40 is in a strip shape and is placed on the bearing plane 121 for reading and avoiding the random movement of the test paper 40. Specifically, the receiving plane 121 and the upper surface of the operation side 10 may be parallel or inclined, that is, the receiving plane 121 and the upper surface of the operation side 10 may be arranged at an angle of 0 to 80 degrees. Of course, the receiving space 12 here includes a receiving plane 121, but a curved surface is also possible, and the receiving plane 121 is taken as an example here.

Preferably, the receiving plane 121 is disposed at 15 to 25 degrees from the upper surface of the operation side 10. The angle setting can make people easily see clearly when watching. And in the present embodiment, it is set to 18 degrees.

When the receiving plane 121 is parallel to the upper surface of the operation side 10, the receiving plane 121 penetrates through the detection tank 11, but is higher than the highest liquid level of the detection tank 11 after the eluent is placed in the detection tank 11, so that the eluent is prevented from entering the receiving plane 121, and the whole receiving plane 121 is covered, so that the sample washing of the detection test paper 40 is caused, the detection result is affected, in this case, the detection test paper 40 is inserted into the detection tank 11, the eluent is dipped, and then the detection test paper 40 is obliquely placed into the receiving plane 121. When the receiving plane 121 and the upper surface of the operation side 10 are disposed in an inclined manner, the bottom point of the receiving plane 121 or the extending surface of the receiving plane 121 is lower than the highest liquid level of the detection tank 11 after the eluent is placed in the detection tank 11, so that the detection test paper 40 can be directly inserted into the detection tank 11 from the sample-adding side of the detection test paper 40 after being placed in the receiving plane 121, and dipped in the eluent to wait for the detection result.

As shown in fig. 5 and 6, the operation side 10 is further provided with a recessed position 13 on a side of the detection receiving position 12 away from the detection groove 11, and the recessed position 13 passes through a side surface of the detection unit platform. When the test paper 40 needs to be taken out or put in, the test paper 40 is held by hand and inserted into the bearing plane 121, and the concave position 13 can just avoid fingers, and certainly, when the test paper 40 is taken out, as shown in fig. 6, the bottom of the tail end of the test paper 40 is not blocked, so that the fingers can conveniently stretch in and the test paper 40 is taken out.

The detection unit platform integrally adopts a shell structure, is processed in a plastic suction mode during processing, is high in processing speed and low in cost, and can greatly save the cost especially for mass production.

Example two:

the present embodiment differs from the first embodiment as follows.

As shown in fig. 7 to 10, the operation side 10 is further provided with a receiving platform 14, and the receiving platform 14 is located on a side of the recessed portion 13 away from the receiving position 12. The receiving position 12 can be used for receiving the tail end of the sampler 30, especially under the condition that the elution time is required, the user experience is influenced by always holding the sampler 30 by hand, the sampler 30 is directly put down, the sampler 30 is long, and the eluted part is easy to warp due to the lever principle, so that the receiving table 14 arranged at the moment receives the sampler 30 and frees the hands of people. Although the height of the receiving platform 14 can be set higher, if the height is too high, the overall height of the platform of the detecting unit is greatly increased, so that the connecting line between the receiving part of the receiving platform 14 and the lower part of the detecting groove 11 is adopted without obstruction.

As shown in fig. 7 to 10, the receiving plane 121 includes a first section plane 1211 and a second section plane 1212, the first section plane 1211 is close to the detection slot 11 relative to the second section plane 1212, a height difference is provided at a junction of the first section plane 1211 and the second section plane 1212, and the second section plane 1212 is higher than the first section plane 1211. When the eluent is placed, if the eluent splashes onto the bearing plane 121, the eluent is contacted with the detection test paper 40 when the detection test paper 40 is placed, so that sample washing is caused, and the detection result is influenced. In the embodiment, even if the eluent splashes, the eluent basically splashes to the side close to the detection groove 11, that is, on the first section plane 1211, but there is a height difference between the first section plane 1211 and the second section plane 1212, and the second section plane 1212 is higher, so that the detection test paper 40 is placed, the lower side is located near the detection groove 11, and the higher side is located on the second section plane 1212, so that the first section plane 1211 is suspended to avoid contacting the detection test paper 40. In other alternatives, the receiving plane 121 may be provided in three or more segments, as shown in fig. 7, which is an example of providing three segments for the receiving plane 121.

As shown in fig. 9 and 10, the upper surface of the sidewall of the first section plane 1211 is inclined, the difference between the inclination angle of the first section plane 1211 and the inclination angle of the second section plane 1212 is not greater than 5 degrees, and the highest point of the upper surface of the sidewall of the first section plane 1211 is not higher than the highest point of the second section plane 1212 by 5 mm. When the test strip 40 is placed, the result display area of the test strip 40 is located on the first section plane 1211, and if there are higher side walls on both sides of the first section plane 1211, the result display area of the test strip 40 is affected by the shadow under the effect of the side-emitting light, which is inconvenient for reading and affects the viewing of the result. The test paper 40 is received on the second section plane 1212, and the inclination angle of the test paper 40 is close to the angle of the second section plane 1212, and the highest point of the second section plane 1212 is higher, so the upper surface of the sidewall of the first section plane 1211 is close to the inclination angle of the surface of the test paper 40, and the height is also close, thereby avoiding the shadow effect of the light. Specifically, the upper surface of the sidewall of the first section 1211 is inclined at the same angle as the second section 1212. In other alternatives, the sidewall of the first section 1211 and the upper surface of the sidewall of the second section 1212 may be inclined at the same angle.

As shown in fig. 7, a limiting protrusion 1213 is provided on a side wall of the receiving site 12, and the limiting protrusion 1213 is a curved protrusion such that the minimum width of the receiving site 12 is narrowed for limiting the test paper 40 and the sampler 30. Compared with the case of the first embodiment, the side wall of the receiving position 12 of the first embodiment is a plane, and if an eluent splashes to the side wall, the eluent is likely to remain on the surface and contact with the detection test paper 40 to cause sample washing of the detection test paper 40, but in the embodiment, the structure of the limiting protrusion 1213 is adopted, so that the residual amount of the eluent can be reduced, the contact surface between the detection test paper 40 and the side wall of the receiving position 12 is reduced, and the limiting effect can also be achieved.

The rest of the structure is the same as the first embodiment, and the description is not repeated here.

Example three:

the difference between this embodiment and the second embodiment is as follows.

As shown in FIG. 11, the receiving site 12 includes a receiving hole 122, the receiving hole 122 is disposed at the edge of the detection tank 11, and the receiving hole 122 is communicated with the detection tank 11, so that the eluent in the detection tank 11 can enter the receiving site 12, and during detection, the sample-loading side of the test paper 40 is directly inserted into the receiving hole 122.

The rest of the structure is the same as the embodiment, and the description is not repeated here.

When the drawing description is quoted, the new characteristics are explained; in order to avoid that repeated reference to the drawings results in an insufficiently concise description, the drawings are not referred to one by one in the case of clear description of the already described features.

The above embodiments are intended to be illustrative, and should not be construed as limiting the scope of the invention, and the technical solutions, objects and effects of the present invention are described in full herein.

The above examples are not intended to be exhaustive list of the present invention, and there may be many other embodiments not listed. Any replacement and improvement made on the basis of not violating the conception of the utility model belong to the protection scope of the utility model.
