Large livestock animal saliva sample acquisition and collecting device

Abstract

The invention discloses a large livestock animal saliva sample acquisition and collection device comprising a chewing tube, cylindrical saliva collecting cotton, a rubber pull ring and a plurality of pull ropes; the chewing tube is provided with a saliva collection interlayer cavity, the outer wall of the chewing tube is provided with a plurality of saliva filtering holes communicated with the saliva collection interlayer cavity, and the bottom end of the chewing tube is provided with a saliva outlet communicated with the saliva collection interlayer cavity; the saliva outlet is sleeved with a saliva collecting pipe, a vertical fixing rod is fixed to the outer wall of the chewing pipe, and a handle is fixed to the lower end of the vertical fixing rod; the cylindrical saliva collecting cotton is fixedly sleeved on the top of the inner tube wall; the bottom of the saliva collecting cotton penetrates through the rubber pull ring, and the saliva collecting cotton and the rubber pull ring are in tight fit; and one end of each pull rope is fixed with the rubber pull ring, and the other end of each pull rope penetrates through the bottom end of the chewing tube and is fixed with a handle plate. The device does not need to fix an animal, does not damage the experimental animal, has low requirement on the skill level of experimenters, is simple and convenient to operate, and is relatively pure in collected saliva sample and small in influence on the experimental result.

Description

Technical field [0001] The present invention relates to the field of experimental biology and medicine, and more specifically, to a large livestock animals saliva sample collection and collection device. Background technique [0002] Research shows that a variety of pathogens can be used as a saliva sample vector for precise identification of pathogens by molecular biology techniques, to distinguish between different pathogens loading period, to provide early warning of a pathogen infection of the body. The field of human medicine is the health of human saliva likened to a mirror, showing the importance of clinical medicine saliva sample pairs. The method of collecting a number of animal origin saliva, is divided into: a direct charge method, which is inserted into the oral cavity of the subject animal animal saliva suction pipette with different specifications. But its drawback is that the operation is complicated, the animal is fixed in advance, mechanical stimulation of larger...

AI Technical Summary

Problems solved by technology

Compared with other methods, this method can collect more pure saliva, but it needs to anesthetize the experimental animals one by one / head by head, open the gland and intubate, requiring operators to have a higher technical level, and several The saliva collected is not secreted by the animals under normal conditions, and the collected saliva cannot be measured, which affects the accuracy of the experiment.
