[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] The present invention provides the following preferred embodiments:

[0038] Example 1, as Figure 1-Figure 7 As shown, a hemoglobin and calprotectin combined detection kit includes two shells 11, each of which is equipped with a test strip 12. The two test strips 12 are used for detecting hemoglobin and calprotectin, respectively. The test strips 12 are conventional and will not be described in detail here. They also include a loading mechanism, a connecting mechanism, and two sample ports 15. Each sample port 15 is fixedly mounted on one end of the surface of one shell 11. The sample port 15 facilitates feeding. When in use, the sample can drip onto the sample pad on the test strip 12 through the sample port 15 to facilitate subsequent detection.

[0039] By arranging two test strips 12 in one test kit, hemoglobin / calprotectin can be detected simultaneously, which is simple to operate and does not require testing one by one;

[0040] The feeding mechanism includes a sample injection cylinder 16, a sample injection tube 17, a sampling assembly, and two sample outlet tubes 21. The two sample injection cylinders 16 are fixed between one end of the two housings 11. The sample injection tube 17 is fixedly installed at the bottom end of the sample injection cylinder 16. The two sample outlet tubes 21 are symmetrically installed on both sides of the sample injection cylinder 16. The other end of each sample outlet tube 21 is inserted into the interior of a sample port 15. The sampling assembly is located inside the sample injection cylinder 16.

[0041] During use, the sampling assembly can transport the sample to the interior of the sampling cylinder 16 through the sampling tube 17, and then the sample can be diverted to the two sample ports 15 through the two sample outlet tubes 21. At this time, the sample can drip onto the sample pads on the two test papers 12, achieving the effect of synchronous loading without the need for separate loading.

[0042] like Figure 1-Figure 7 As shown, the sampling assembly includes a piston plate 19, a pull rod 20, a connecting seat 28 and two opening and closing components;

[0043] The piston plate 19 is slidably arranged inside the sampling cylinder 16. A through hole is provided in the middle of the piston plate 19, which penetrates the piston plate 19. The setting of the through hole allows the sample to pass through, making it convenient for the sample to enter the two sample outlet tubes 21. The connecting seat 28 is located above the through hole and is fixedly installed on the top of the sampling cylinder 16. The setting of the connecting seat 28 is used to prevent the through hole from being blocked, thereby achieving a avoidance effect. The pull rod 20 is slidably arranged on the top of the sampling cylinder 16, and the bottom end of the pull rod 20 is fixedly connected to the connecting seat 28. The two opening and closing components are respectively located above the sampling tube 17 and the through hole. The opening and closing components are used to open or close the opening on the sampling tube 17 and the through hole.

[0044] During use, in the initial state, the piston plate 19 is located below the interior of the injection cylinder 16. When sampling is required, the injection tube 17 is inserted into the sample, and the pull rod 20 is pulled down. The piston plate 19 can be driven to slide upward inside the injection cylinder 16 through the connecting seat 28. At this time, the opening and closing component above the injection tube 17 opens, and the opening and closing component on the piston plate 19 closes, and the sample enters the interior of the injection cylinder 16 through the injection tube 17;

[0045] When the pull rod 20 is pressed, the piston plate 19 moves downward, and the opening and closing component above the sample injection tube 17 closes, and the opening and closing component on the piston plate 19 opens, so that the sample between the piston plate 19 and the sample injection tube 17 can enter the top of the piston plate 19 through the through hole;

[0046] Repeated pressing increases the amount of sample in the sample injection cylinder 16 until the sample flows out from the sample outlet tube 21 .

[0047] like Figure 1-Figure 7 As shown, each opening and closing assembly includes a cover plate 23, a fixing seat 33, two hinged rods 24, two mounting rods 25 and two return springs 26;

[0048] The cover plate 23 is located above the through hole or the opening of the sample injection tube 17. A fixing seat 33 is fixed to one side of the cover plate 23. Two hinged rods 24 are respectively fixed to the two sides of the fixing seat 33. One end of the two mounting rods 25 is fixedly mounted on the top of the cover plate 23. The other end of each mounting rod 25 is hinged to a hinged rod 24. Two return springs 26 are respectively sleeved on the two hinged rods 24. The two ends of each return spring 26 are respectively connected to the fixing seat 33 and a mounting rod 25. The return spring 26 can achieve a quick reset effect.

[0049] During use, after the sampling tube 17 is inserted into the sample, the pull rod 20 is pulled up to move the piston plate 19 upward. Due to the sealing, the air between the piston plate 19 and the sampling tube 17 will be reduced and the pressure will become smaller. At this time, the cover plate 23 on the sampling tube 17 is pushed open by the sample, and the sample enters the interior of the sampling cylinder 16. When the pull rod 20 is pressed downward, the piston plate 19 moves downward. At this time, since there is a certain amount of sample between the piston plate 19 and the sampling tube 17, when the piston plate 19 is pressed down, the sample under the piston plate 19 is compressed, and the cover plate 23 on the sampling tube 17 is closed under the action of pressure. At the same time, the cover plate 23 on the piston plate 19 will be opened due to the action of pressure, and the sample enters the top of the piston plate 19 through the through hole. The reciprocating operation increases the sample above the piston plate 19 until the sample flows out from the sample outlet tube 21.

[0050] like Figure 1-Figure 7 As shown, the connecting mechanism includes two fixing hoops 29 and a plurality of connecting rods 14;

[0051] The two fixing hoops 29 are both sleeved on the outside of the injection cylinder 16, and the two sides of the two fixing hoops 29 are respectively fixedly connected to the two shells 11. The fixing hoops 29 are used to install and fix the injection cylinder 16. Multiple connecting rods 14 are equidistantly arranged between the two shells 11, and both ends of each connecting rod 14 are fixedly connected to the two shells 11. Multiple connecting rods 14 are used to connect the two shells 11, so that it can become the main body of the detection box.

[0052] like Figure 1-Figure 7 As shown, a sealing ring 22 is installed on the inner wall of each sample port 15 to improve the sealing performance. Each sealing ring 22 is arranged between the sample port 15 and the sample outlet tube 21 to increase the sealing performance between the sample port 15 and the sample outlet tube 21 to prevent the sample from flowing out.

[0053] like Figure 1-Figure 7 As shown, the bottom end of the sample injection tube 17 is provided with a cover 18 for sealing, and the inner wall of the cover 18 and the outer wall of the sample injection tube 17 are interference fit;

[0054] By arranging a cover 18 on the outside of the sampling tube 17, the sampling tube 17 can be protected. Before the detection reagent is used, the cover 18 can isolate the sampling tube 17 to prevent other objects from accidentally touching the sampling tube 17 and causing subsequent sample contamination. At the same time, after sampling, the cover 18 can block the sample on the sampling tube 17 to prevent the sample from contaminating the surrounding environment.

[0055] like Figure 1-Figure 7 As shown, a limiting ring 32 for limiting the position is installed on the inner wall of the sample injection cylinder 16. The limiting ring 32 is installed below the sample outlet tube 21. The setting of the limiting ring 32 can prevent the piston plate 19 from being moved to a position exceeding the sample outlet tube 21.

[0056] like Figure 1-Figure 7 As shown, a supporting foot 30 is fixed on both sides of the bottom end of each shell 11, and the bottom section of each supporting foot 30 is flush with the bottom section of the cover shell 18, which can facilitate placement and enable the test box to be placed stably and horizontally to avoid tilting that affects the accuracy of the test results.

[0057] like Figure 1-Figure 7 As shown, an observation window 13 is provided at the top of each shell 11 for easy observation, and a transparent panel is embedded in the interior of each observation window 13. The transparent panel not only facilitates observation but also achieves a sealing and protective effect.

[0058] like Figure 1-Figure 7 As shown, a pinching plate 31 is provided at one end of the two shells 11 away from the sample port 15, and each shell 11 is fixedly connected to the pinching plate 31. The pinching plate 31 makes it convenient for the user to hold the detection kit, making it easy to operate and use.

[0059] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
