[0026] In order to better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0027] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusion, for example, a process, method, region, product or device comprising a series of steps or units does not have to be limited to the clearly listed steps or units, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] The following will be described in detail Figures 1-5 and the present application

[0029] Embodiment one, refer to Figures 1-5The illustrated home rapid testing device includes a solution channel, a test strip chamber 1, and a sampling rod 2. A valve 3 is provided in the solution channel, dividing it into an upper chamber 4 and a lower chamber 5. The test strip chamber 1 is connected to the lower chamber 5, and a test strip 6 is provided inside the test strip chamber 1. A bottom cover 7 is provided at the opening of the lower chamber 5, and the bottom cover 7 fits tightly with the lower chamber 5. A sealing element 8 is slidably disposed in the upper chamber 4, and a solution chamber containing a solution is provided between the sealing element 8 and the valve 3. An air compression chamber is provided between the solution and the sealing element 8, and the solution chamber is connected to the air compression chamber. A through hole is provided on the sealing element 8 (which can be a sealing plug), through which the sampling rod 2 passes and contacts the solution. The sampling rod 2 and the sealing element 8 are movable within the solution channel. The sampling rod 2 can open the valve 3 and enter the lower chamber. A push stop 9 is provided on the sampling rod 2, located on the side of the sealing element 8 away from the valve 3, and is larger than the through hole on one side of the test strip chamber 1. The device is equipped with a insert 10, and a test strip 6 (used to detect transferrin or hemoglobin in feces) is placed on the insert 10. The insert 10 has a through hole at one end near the bottom cover 7. The lower cavity 5 is connected to the test strip 6 in the test strip cavity 1 through the through hole. Thus, the user inserts the sampled sampling rod 2 into the solution channel, first passing through the seal 8 (the seal 8 has a hole in the center) until it reaches the solution. The sample at the end of the sampling rod 2 mixes with the solution. Then, the user pushes the sampling rod 2 until the end of the sampling rod 2 opens the valve 3. At the same time, the pusher 9 on the sampling rod 2 abuts against the seal 8, causing the seal 8 to move towards the valve 3. The seal 8 compresses the air in the lower cavity 5, creating pressure above the solution. The air pressure pushes the solution with the sample out from the opened valve 3, through the through hole, into the test strip cavity 1, and into contact with the test strip 6 placed at the insert 10, thus conveniently completing home testing.

[0030] Further optimization involves ensuring that the mixed solution in the lower chamber 5 flows out of the valve 3 quickly and sufficiently, so that the height of the air compression chamber is not less than 5 mm, thus ensuring that there is enough gas above the solution to make the air pressure high enough.

[0031] Further optimizations include, for example Figure 1 As shown, in order to facilitate hand-held operation of the sampling rod 2, a handle 11 is provided at the suspended end of the sampling rod 2. The testing personnel can hold the handle 11 to operate the sampling rod 2 conveniently. In addition, in order to facilitate sample acquisition, a sampling groove is provided at one end of the sampling rod 2. When in contact with the sample, the sampling groove can retain the sample. That is to say, the sampling groove end of the sampling rod 2 is set in the solution cavity and in contact with the solution.

[0032] Further optimization is that the structure of the valve 3 can meet the sampling rod 2 top open, can be a sheet, when producing, the sheet is integrally formed with the side wall of the solution channel, and the hardness of the sampling rod 2 is greater than the hardness of the sheet, and the optimal thickness of the sheet is less than 0.9mm (for example, 0.8mm, 0.7mm, 0.5mm, 0.4mm, etc.), so that the sampling end of the sampling rod 2 can be provided as a sharp end to ensure that the sheet is poked, and the valve 3 can be provided as a plunger, which is blocked at the bottom of the lower cavity 5, and when the end of the sampling rod 2 is abutted, the plunger is pushed away from the bottom of the lower cavity 5 to make the sample solution flow out.

[0033] Further optimization is that, in order to reduce production cost, the sampling rod 2, the push 9 and the handle 11 are integrally injection molded to improve production efficiency and reduce production cost, and in order to further reduce production cost, the bottom cover 7 and the insert sheet 10 can also be produced by integrally injection molding.

[0034] Further optimization is that the test paper cavity 1 is transparent at least on one side, and the inner wall of the transparent side is in contact with the test paper, so that the state of the test paper strip 6 can be clearly and conveniently observed through the transparent side, so as to obtain the detection result.

[0035] Further optimization is that a limit is arranged on the sampling rod 2, and the limit is used for fixing the sampling rod.

[0036] Further optimization is that the bottom cover 7 and the insert sheet 10 are integrally formed and are made of elastic material.

[0037] The working principle of the utility model is: when in use, the sampler is inserted into the solution channel, first passes through the sealing element 8, and reaches the solution until the sample at the end of the sampling rod 2 is mixed with the solution, then the sampling rod 2 is pushed until the end of the sampling rod 2 opens the valve 3, at the same time, the push 9 on the sampling rod 2 abuts against the sealing element 8, the sealing element 8 moves towards the valve 3, the sealing element 8 compresses the air in the lower cavity 5, the pressure above the solution is generated, the air pressure pushes the solution with the sample to flow out from the opened valve 3, flows into the test paper cavity 1 through the through hole, and contacts the test paper strip 6 placed at the insert sheet 10, so that the home detection is conveniently completed.

[0038] The above is only the preferred embodiment of the application, and the utility model is not limited to the above examples. It can be understood that other improvements and changes directly derived or thought by those skilled in the art without departing from the spirit and concept of the utility model should be considered to be included in the protection scope of the utility model.
