[0002] Stool sampling is to obtain important information about the health of the digestive system through laboratory testing and analysis, which is used to diagnose diseases, monitor treatment effects and study intestinal microecology. Stool is generally collected through a sampler, and then the sample is stored by placing the sampler in a test tube, which is then sealed with a cover and transported to the laboratory for monitoring and analysis.
[0003] However, in the prior art, the sampler is generally an integrated type, so when the sampler collects stool and places it in a test tube, the stool may accidentally stick to the outer wall of the test tube, which may lead to cross infection or contamination of other places, increase the risk of infection, and cause discomfort to the collector. In view of the above problems, a stool sampler is proposed by a person skilled in the art to solve the above problems. Utility Model Content
[0004] In order to make up for the above deficiencies, the utility model provides a stool sample sampler, aiming to improve the problem that the samplers in the prior art are generally integrated.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A stool sample sampler comprises a test tube and a cover body, wherein the bottom end of the cover body is fixedly connected to the sampling tube, a mounting groove is provided inside the sampling tube, a spring is fixedly connected to the inner wall of the mounting groove, a limit block is fixedly connected to the bottom end of the spring, a push rod is fixedly connected to the top end of the limit block, and a sampling hook is fixedly connected to the bottom end of the limit block.
[0007] Furthermore, a threaded ring is fixedly connected to the outside of the test tube, and a threaded groove is formed on the inner wall of the outer cover.
[0008] Furthermore, a sealing ring is fixedly connected to the inside of the cover body, and the inside of the sealing ring abuts against the outside of the push rod.
[0009] Furthermore, the interior of the installation groove is slidably connected to the exterior of the limiting block.
[0010] Furthermore, the interior of the cover body is slidably connected to the exterior of the push rod, and the interior of the mounting groove is slidably connected to the exterior of the sampling hook.
[0011] Furthermore, the interior of the test tube is slidably connected to the exterior of the sampling tube.
[0012] Furthermore, the outside of the test tube is connected to the outside of the cover body by threads.
[0013] Furthermore, a hook is provided at the bottom end of the sampling hook.
[0014] The utility model has the following beneficial effects:
[0015] 1. In the utility model, the sampling hook can be pushed out to collect feces through the mutual cooperation of the installation groove, spring, limit block, push rod, sampling hook and other structures. After the collection, the sampling hook is hidden in the sampling tube through the spring reset activity, so that when the sampling tube is placed, the feces will not be stained with the outer wall of the test tube, thereby effectively reducing the risk of cross contamination, ensuring that the collected samples are clean and pure, and creating a hygienic and tidy working atmosphere.
[0016] 2. In the utility model, the sealing ring, the threaded ring, the threaded groove and other structures are used in coordination with each other, so that the cover and the test tube can be sealed, thereby preventing the stool sample from overflowing or contaminating the outer wall of the test tube, ensuring the purity and hygiene of the sample, and preventing the odor from spreading to the surrounding environment, thereby improving the comfort of the workplace.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a stool sample sampler, including a test tube 1 and a cover body 2, the outside of the test tube 1 is threadedly connected to the outside of the cover body 2, the bottom end of the cover body 2 is fixedly connected to the sampling tube 3, and the inside of the test tube 1 is slidably connected to the outside of the sampling tube 3.
[0024] Specifically, the test tube 1 is threadedly connected to the cover body 2, so that the cover body 2 can seal the test tube 1, and the cover body 2 fixes the sampling tube 3 so that the sampling tube 3 can stably perform sampling, and the test tube 1 limits the sampling tube 3 so that the sampling tube 3 will not deviate when moving.
[0025] Reference Figure 1-Figure 3 A mounting groove 4 is provided inside the sampling tube 3, a spring 5 is fixedly connected to the inner wall of the mounting groove 4, a limiting block 6 is fixedly connected to the bottom end of the spring 5, the inside of the mounting groove 4 is slidably connected to the outside of the limiting block 6, a push rod 7 is fixedly connected to the top of the limiting block 6, the inside of the cover body 2 is slidably connected to the outside of the push rod 7, a sampling hook 8 is fixedly connected to the bottom end of the limiting block 6, a hook is provided at the bottom end of the sampling hook 8, and the inside of the mounting groove 4 is slidably connected to the outside of the sampling hook 8.
[0026] Specifically, the mounting groove 4 and the limit block 6 fix the spring 5, so that the spring 5 can stably perform elastic deformation. The mounting groove 4 limits the limit block 6, the push rod 7, and the sampling hook 8, so that the limit block 6, the push rod 7, and the sampling hook 8 are stable when moving. By pushing the push rod 7 downward, the limit block 6 is driven downward, and then the sampling hook 8 is driven downward, so that stool can be sampled.
[0027] Reference Figure 3 The outside of the test tube 1 is fixedly connected with a threaded ring 10, the inner wall of the cover body 2 is provided with a threaded groove 11, the inside of the cover body 2 is fixedly connected with a sealing ring 9, and the inside of the sealing ring 9 abuts against the outside of the push rod 7.
[0028] Specifically, a threaded ring 10 is provided on the outside of the test tube 1 and a threaded groove 11 is opened on the inner wall of the cover body 2, so that the test tube 1 and the cover body 2 are sealed when connected. A sealing ring 9 is provided inside the cover body 2, and the sealing ring 9 is in contact with the push rod 7, so that the connection between the cover body 2 and the push rod 7 is sealed, thereby preventing odor from spreading to the surrounding environment.
[0029] Working principle: when it is necessary to sample stool, the cover body 2 is taken out, thereby driving the sampling tube 3 to be taken out, and then the push rod 7 is pushed downward, thereby driving the limit block 6 to move downward, and then pulling the spring 5 to make elastic deformation, thereby driving the sampling hook 8 to move downward, and then sampling stool is performed, and then the spring 5 is reset, thereby driving the limit block 6 to move upward, and then the sampling hook 8 moves with it, and then the sampling hook 8 is retracted into the sampling tube 3, so that when the sampling tube 3 is placed in the test tube 1, the stool will not stick to the outer wall of the test tube 1, and then by twisting the cover body 2, the test tube 1 and the cover body 2 are sealed, thereby completing the sampling of stool.
