Description

Technical Field

[0001] The utility model relates to a device for collecting intestinal flora, in particular to a device for collecting tree shrew intestinal flora, belonging to the technical field of experimental apparatus for tree shrews. Background Technique

[0002] The tree shrew is an animal of the genus Tupaia in the family Tupaiidae. It is very similar to humans in terms of physiological and biochemical indexes and their regulatory mechanisms. Coupled with the advantages of being more convenient to raise, observe and operate, an animal model of human diseases can be replicated. In the research experiment of intestinal flora, the tree shrew is fixed, and defecation is promoted by massaging the abdomen or squeezing the tip of the animal's tail. An intestinal flora collection device can be used to collect the feces of the tree shrew for the study of intestinal flora.

[0003] Among them, the "device for collecting tree shrew intestinal flora" disclosed in the patent application No. "201821101487.2" is also an increasingly mature technology, including a tree shrew fixing device and a flora collection box. The flora collection box is arranged below the base of the tree shrew fixing device. There is a track on the base that matches the upper part of the flora collection box, forming a drawer structure. There is a through hole on the base that is consistent with the opening of the flora collection box. Using this sampling device, samples are collected first and then transferred to a sampling tube. There is a filter membrane in the sampling device, and urine can be excluded, reducing the pollution of urine to the samples. The intestinal flora samples can directly enter the sampling tube from the outlet tube, shortening the sample collection time and reducing the microbial pollution of the samples by the environment during sampling. At the same time, it can fix experimental animals time-saving and labor-saving, reduce the struggle of experimental animals, solve the problem of multiple-person operation, improve the sampling efficiency, prevent the pollution of intestinal flora samples, facilitate sample collection, the device can be reused, reduce the sampling cost, and the operation is very convenient. After further retrieval, the "device for collecting intestinal flora" disclosed in the patent application No. "202011064129.0" includes a support mechanism, and a fixing component installed at the top of the support mechanism for fixing experimental animals, and a feces collection component installed on one side of the fixing component and connected to the support mechanism for collecting the feces of experimental animals. The invention has a simple structure and very convenient operation. Using this experimental animal fixing component can fix experimental animals time-saving and labor-saving, solve the problem of multiple-person operation, facilitate the operation of experimental personnel, and at the same time reduce the struggle of animals during the experiment. It has a low cost, has good market promotion prospects, can improve the sampling efficiency, prevent the pollution of intestinal flora samples, facilitate sample collection, is easy to clean and disinfect, and can be reused.

Then, pass the limbs of the tree shrew through between the third strap 302 and the support plate 5, tighten the third strap 302, and adhere the third rough surface magic tape 307 and the third hook surface magic tape 308 to fix the limbs of the tree shrew, thereby fixing the tree shrew.

[0032] Embodiment 3:

[0033] The collection mechanism 4 includes a moving plate 401. The moving plate 401 is slidably connected to the other side of the top end of the bottom plate 1. A placement groove 402 is provided in the middle of the top end of the moving plate 401 to keep the disposable test cup stable through the placement groove 402. Two side plates 403 are fixedly connected to the other side of the top end of the bottom plate 1. Moving seats 404 are fixedly connected to the bottoms of both sides of the moving plate 401. A sliding groove 405 which is slidably matched with the moving seat 404 is provided in the middle of the side plate 403. A limiting rod 406 which is slidably matched with the moving seat 404 is fixedly connected inside the sliding groove 405. The sliding groove 405 and the limiting rod 406 limit the moving position of the moving seat 404, and further limit the moving position of the moving plate 401 and the disposable test cup, so as to adjust the position of the disposable test cup and accurately collect feces;

[0034] Specifically, first, place the disposable test cup into the placement groove 402 to prevent the disposable test cup from tilting. Then, push the moving plate 401 and push the moving plate 401 towards the tree shrew to accurately adjust the position for collecting feces and prevent feces from scattering on the bottom plate 1.

[0035] During use, first pass the head of the tree shrew through between the second strap 301 and the support plate 5, tighten the second strap 301, stick the second hook-and-loop fastener with a fuzzy surface 304 to the second hook-and-loop fastener with a hook surface 305 to fix the head of the tree shrew. Then pass the limbs of the tree shrew through between the third strap 302 and the support plate 5, tighten the third strap 302, and stick the third hook-and-loop fastener with a fuzzy surface 307 to the third hook-and-loop fastener with a hook surface 308 to fix the limbs of the tree shrew, thereby fixing the tree shrew.

[0036] Then press the baffle 9 to make the baffle 9 enter the connection shell 8, compress the spring 10. Then put the tail of the tree shrew into the through groove 7, and then release the baffle 9. Under the action of the spring 10, the baffle 9 blocks the through groove 7 to limit the tail of the tree shrew between the through groove 7 and the baffle 9. Then pull the first strap 15 to fix the tail end of the tree shrew's tail between the second upright post 6 and the first strap 15, so as to be able to fix the tail of the tree shrew, prevent feces from sticking to the tail of the tree shrew, and avoid affecting the collection of feces. Finally, place the disposable test cup into the placement groove 402 to prevent the disposable test cup from tilting. Then push the moving plate 401 and push the moving plate 401 towards the tree shrew, which can accurately adjust the position for collecting feces, so that the feces accurately fall into the disposable test cup for collection.
