Description

Technical Field

[0001] The invention relates to the technical field of saliva sampling, in particular to a sampling device for animal saliva. Background Art

[0002] Saliva sampling plays an important role in animal quarantine. It can not only be used for disease diagnosis, monitoring pathogen prevalence, and assessing animal health, but also has the advantages of reducing animal stress response and easy sampling. Therefore, in animal quarantine work, the advantages of saliva sampling should be fully utilized to contribute to the prevention and control of animal diseases and the protection of animal health. When veterinarians sample pig saliva, they usually hang cotton balls in the pig house. When the pigs chew the cotton balls, their saliva will remain on the cotton balls, and finally squeeze the saliva on the cotton balls into the collection bag. However, when squeezing the cotton balls containing animal saliva for sampling, food residues, hair and other impurities are likely to appear in the squeezed saliva, which is difficult to remove while collecting. Some impurities may react with experimental reagents, affecting the accuracy of experimental results, and impurities may clog experimental equipment, such as straws, centrifuge tubes, etc., resulting in equipment damage or experimental failure. At the same time, the hands of sampling staff are easily contaminated with animal saliva, and some saliva containing viruses contains pathogens, which leads to safety hazards during sampling.

[0003] The patent document with the announcement number CN220124720U discloses an animal saliva sampling device, which specifically includes a chewing net bag, a saliva absorber arranged inside the chewing net bag, and an isolation bag turning assembly arranged inside the chewing net bag. The utility model can pull the elastic isolation bag through the hanging piece when it is necessary to squeeze the saliva absorber that absorbs enough saliva to promote the discharge of saliva, so as to make the elastic isolation bag as a whole turn over from the inside to the outside, and wrap the chewing net bag and the saliva absorber inside. At this time, the user can manually squeeze the outer surface of the still clean elastic isolation bag turned over, and squeeze the saliva in the saliva absorber out of the through hole arranged on the surface of the elastic isolation bag, without the need for other devices to participate in the operation. While the operation is fast, it can also effectively prevent the user's body from contacting the chewing net bag with saliva. However, the patent still has the following problems in actual use:

[0004] When the sampling device is in use, the elastic isolation belt is still prone to rupture when it is pulled when the animal is chewing, resulting in leakage of animal saliva. When in use, the staff still needs to touch the elastic isolation with their hands to squeeze the saliva absorber, resulting in the risk of contact with the animal saliva when the staff is sampling the animal saliva. In addition, it is difficult to filter the impurities contained in the animal saliva directly by squeezing, resulting in low purity of the saliva sample. At the same time, the presence of impurities may interfere with the experimental process and increase the experimental error.

[0005] Therefore, we propose a sampling device for animal saliva in order to solve the above-mentioned problems. Summary of the invention

[0049] Working principle: Figure 1-Figure 11As shown, when the device is used, first, by rotating the sliding push rod 301, the sliding push rod 301 drives the rotating sleeve 204 to rotate at the fixed handle 201 through the rotating shaft 203, so that the positioning block 206 contracts toward the positioning spring 205. At this time, the retracted and expanded grasping clamp 411 is separated from the rotating groove 102, and when the sliding push rod 301 is turned over to be perpendicular to the sampling tube 101, the positioning block 206 is engaged with the positioning groove 202 and pushes the locking plate 305, so that the locking plate 305 slides on the connecting rod 304 through the locking groove 306, and the push plate 303 and the locking plate 305 fall on both sides of the rotating sleeve 204 respectively, and then the filter plate 501 is aligned with the docking strip 504 through the docking groove 503, and the filter plate 501 falls on one side of the support ring 505.

[0050] Secondly, hold the push plate 303 or the sampling tube 101 and press the adjusting rod 401 to make the adjusting rod 401 slide in the control groove 307, and push the retracting slide rod 403 to slide through the adjusting plate 402. At this time, the guide block 404 slides in the guide groove 405, and the reset spring 420 contracts, and the retracting slide groove 406 pushes the retracting rotating rod 408 through the sliding shaft 407, so that the retracting rotating rod 408 rotates and unfolds on the rotating seat 410 through the rotating block 409, and then the chewed sampling cotton ball is clamped between the retracting rotating rod 408 and the retracting clamp 411, and the sliding push rod 301 is rotated again to make the silicone plate 308 fall on the inner side of the sampling tube 101.

[0051] Next, by pushing the push plate 303, the push plate 303 drives the sliding push rod 301 and the limiting rod 302 to slide in the sliding groove 207 and the limiting groove 208 respectively, and the silicone plate 308 slides in the sampling tube 101, and the sampling cotton ball is squeezed at the filter plate 501. At this time, the retracting and opening grasping clamp 411 rotates at the retracting and opening rotating rod 408, so that the torsion spring 1 412 contracts. At the same time, the slot 502 on one side of the filter plate 501 pushes the claw 416 to expand, so that the claw 416 pushes the retracting and opening folding plate 417 to rotate at the retracting and opening seat 418, and the torsion spring 2 419 is expanded, and then the claw 416 passes through the slot 502 and engages with the filter plate 501.

[0052] Finally, pull the push plate 303 so that the claw 416 drives the filter plate 501 to be taken out, and by pulling the adjusting rod 401, the adjusting sheet 402 pulls the sleeve plate 413 to shrink toward the reset spring 2 421, and the sleeve plate 413 drives the adjusting circular plate 415 to move through the connecting slide rod 414, so that the adjusting circular plate 415 pushes the retracting and expanding folding plate 417 to unfold at the retracting and expanding seat 418, thereby realizing the separation of the claw 416 and the slot 502, and realizing the replacement of the filter plate 501.
