Furthermore, the flow rate is not easily adjustable, resulting in inconsistent sample flow and reduced testing effectiveness. Additionally, the angle of the test strip base plate is generally not adjustable, and there's no need to ensure the sample reaches the designated location, requiring prolonged sample penetration, increasing testing time and further diminishing the test's effectiveness.

[0012] The technical solutions of the present 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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Example 1 See Figures 1-2 A sample guide strip base plate includes a base plate body 1, a sample guide component 2, and an angle adjustment component 3. The sample guide component 2 is installed on the base plate body 1, and the angle adjustment component 3 is installed on the outer side of the base plate body 1. A test strip 4 is attached to the top outer wall of the base plate body 1, and the test strip 4 is located on the top outer wall of the guide groove 201 and the reaction groove 202. The test strip 4 is provided with tearing grooves 5. The test strip 4 is torn by tearing grooves 5, and the reaction of the test strip 4 is observed to determine the sample condition. The top of the guide tube 203 is connected to an inlet tube 6, and a valve 7 is embedded in the inlet tube 6. The valve 7 is opened, and the sample is injected into the guide tube 203 through the inlet tube 6, and then the sample is guided into the guide groove 201 through the guide tube 203. The sample guiding assembly 2 includes a guiding groove 201, a reaction tank 202, a guiding pipe 203, a first threaded hole 204, a piston plate 205, a conical regulating rod 206, a first threaded rod 207, and a first knob 208. The guiding groove 201 is distributed at the top of the base plate body 1, and the reaction tank 202 is located in the middle of the guiding groove 201. A guiding pipe 203 is connected through the inner wall of one end of the guiding groove 201. A conical regulating rod 206 is sleeved inside the guiding pipe 203. A piston plate 205 is fixed to the outer wall of one end of the conical regulating rod 206, and the outer side of the piston plate 205 is sealed to the guiding pipe 204. On the inner wall of 3, a first threaded rod 207 is rotatably connected to one side of the outer wall of the piston plate 205. A first threaded hole 204 is opened at one end of the guide tube 203 corresponding to the position of the first threaded rod 207. A first knob 208 is fixedly connected to the outer wall of one end of the first threaded rod 207. The reaction tank 202 is Z-shaped, and there are four reaction tanks 202. Because the shape of the reaction tank 202 is relatively curved, the sample can be retained in the reaction tank 202 for a longer time. At this time, the test strip 4 is torn open by tearing open the slot 5, and the reaction of the test strip 4 is observed to determine the condition of the sample.

[0014] Working principle: First, according to the type of sample, turn the first knob 208 to rotate the first threaded rod 207. Then, under the action of the first threaded hole 204, the first threaded rod 207 rotates and moves, causing the conical flow regulating rod 206 on the piston plate 205 to move along the guide tube 203. The flow rate of the sample is adjusted by the gap between the conical flow regulating rod 206 and the guide tube 203. At this time, the valve 7 is opened, and then the sample is injected into the guide tube 203 through the inlet pipe 6. Then, the sample is guided into the guide groove 201 through the guide tube 203, and then flows into the reverse flow channel 201. Inside the reaction tank 202, due to its curved shape, the sample can remain in the reaction tank for a longer period of time. At this time, the test strip 4 is torn open by tearing the slot 5, and the reaction of the test strip 4 is observed to determine the condition of the sample. Since the base plate 1 is made of PVC material, it has good cross-linking properties with the test strip 4 and does not react with the reagent, thus avoiding affecting the test results of the sample. The sample can be guided to a designated position, and the flow rate of the sample can be adjusted to ensure that the flow rate of the sample remains consistent, thereby improving the test effect.

[0015] Example 2 See Figure 1 and Figure 3 The angle adjustment assembly 3 includes an adjustment plate 301, a rotating shaft 302, a base 303, a second threaded hole 304, a second threaded rod 305, an eccentric wheel 306, and a second knob 307. The base 303 is installed on the outer wall of the bottom end of the base plate body 1. The rotating shaft 302 is on the inner walls of both sides of the base 303, and the other end of the rotating shaft 302 is rotatably connected to the outer wall of the base plate body 1. The second threaded hole 304 is opened on both sides of the base 303. The second threaded rod 305 is internally threaded in the second threaded hole 304. The eccentric wheel 306 is fixedly connected to the outer side of the second threaded rod 305. The adjustment plate 301 is fixedly connected to both outer walls of the base plate body 1, and the adjustment plate 301 is located above the eccentric wheel 306. The second knob 307 is fixedly connected to the outer wall of one end of the second threaded rod 305.

[0016] When testing the sample, turning the second knob 307 causes the second threaded rod 305 to rotate 90 degrees. Then, under the action of the second threaded hole 304, the second threaded rod 305 moves spirally, causing the eccentric wheel 306 to rotate 90 degrees. The protruding part of the eccentric wheel 306 presses against the adjusting plate 301, causing the base plate body 1 to rotate along the rotating shaft 302 on the base 303. The base plate body 1 rotates upward, causing the sample in the guide tube 203 to flow quickly into the reaction tank 202 under the action of gravity, so that the sample reacts with the test strip 4. The angle of the test strip base plate can be adjusted to ensure that the sample can flow to the designated position for testing, avoiding prolonged sample penetration, reducing the testing time, and improving the testing effect.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
