TECHNICAL FIELD
[0001] The present application relates to the technical field of animal sampling equipment for biomedical use, in particular to an animal saliva sampling equipment for veterinary use. BACKGROUND
[0002] Biomedicine is a cross-discipline of medicine, life science and engineering technology, which mainly studies medical problems through biological and engineering means. It covers fields such as genetic engineering, immunology and biological medicine, and is applied to vaccine research and development, pathological diagnosis and medical equipment development. Biomedicine requires basic knowledge of medicine and biology, and on the other hand, it requires in-depth and solid learning of electronic and information professional knowledge such as medical electronics, medical signal detection and processing, medical imaging and medical image processing, medical pattern recognition, medical instrument principle and design, etc. A veterinarian is a doctor who prevents, diagnoses and treats diseases in animals. Specifically, a veterinarian is a worker who uses medical methods to promote the coordination between the body of an animal (including wild animals and poultry and livestock and aquatic animals) and microorganisms and the natural environment.
[0003] In veterinary medical diagnosis, such as infectious disease screening, hormone-related disease screening, toxicant exposure and poisoning diagnosis, drug concentration monitoring and compliance inspection, metabolite and nutritional status analysis, the core is to obtain biomarkers that can reflect the health, metabolism or environmental exposure state of the animal through non-invasive means, and the saliva sample of the animal needs to be sampled. The traditional method of sampling animal saliva is to use a throat swab to dip the inner wall of the oral cavity to sample. Such a method is difficult to get the cooperation of the animal, and there is a sampling difficulty. The swab used for various animals is usually the same, such as using a conventional adult swab for small animals such as cats and dogs. Due to poor cooperation, restraint is needed to sample, and struggling leads to insufficient sampling volume (usually <0.1 mL); short handle swabs are used for large animals such as cattle and horses, and it is difficult to reach the opening of the parotid duct, and the sample is easily mixed with feed residues. It is difficult for veterinarians to restrain animals when they go out for diagnosis or sampling, and it is not convenient to use, so it is difficult to sample different animals in different ways, thus causing certain inconvenience in sampling. Therefore, an animal saliva sampling equipment for veterinary use is proposed. SUMMARY

[0042] In another embodiment, as shown in Figure 2 and Figure 6 One end of the connecting tube 29 is connected with the inside of the installation screw tube 34, the inside of the threaded installation head 30 is connected with the outside of the connecting tube 29 through threads, the end of the connecting tube 29 away from the installation cover 28 is a plug, the air inlet hole 33 is uniformly arranged on the circumference of the plug, a plurality of air outlet holes 35 are arranged on the tube wall of one end of the connecting tube 29, the one-way valve 36 is installed in the inside of the end of the connecting tube 29 close to the air inlet hole 33, and the air outlet holes 35 are located on one side of the one-way valve 36.
[0043] When sampling small animals, the cone cover 11 and the installation screw pipe one 12 are unscrewed from the outside of the branch pipe 1, the installation screw pipe two 34 and the installation cover 28 are threaded and installed on the outside of the branch pipe 1, and the swab cotton ball 32 is placed inside the food-grade silica gel tennis ball 31, which is threaded and installed on the outside of the connecting pipe 29 through the threaded head 30 and the threaded rotation. After installation, the first step is to close the second air valve 8 and open the first air valve 6, and start the first fan 19 to blow air. The inducing smell of the porous rattan stick 25 is introduced into the inside of the connecting pipe 29 through the branch pipe 1, and the airflow is guided through the connecting pipe 29 and limited by the one-way valve 36. The airflow is guided out through the exhaust hole 35, which promotes the formation of the inducing smell outside the swab cotton ball 32. Then the operator licks and bites the food-grade silica gel tennis ball 31 by inducing small animals, and the saliva and slobber are partially adsorbed by the swab cotton ball 32. Then the first air valve 6 is closed and the second air valve 8 is opened, and the second fan 20 is turned on to make the airflow pass through the food-grade silica gel tennis ball 31. The airflow adsorbs the saliva and slobber of the small animals, and part of the liquid adhered to the mesh of the food-grade silica gel tennis ball 31 is guided into the inside of the swab cotton ball 32 as much as possible to increase the sampling sample and reduce the sampling time and difficulty. The food-grade silica gel tennis ball 31 is made of food-grade silica gel, polished round hard plastic such as PP, PE, etc. The surface of such materials is smooth and smooth, without rough texture or fine fibers, which will not cause discomfort to the tongue of small animals such as cat tongue. At the same time, the hardness is moderate, not too hard or too soft and collapsed, which can keep the shape of the air hole stable and will not contaminate the sample. The size of the air hole is divided into different specifications and models for production of various specifications to adapt to the licking or biting of the tongues of different small animals. The recommended size of the hole diameter is not less than 3 mm and not more than 8 mm. Other sizes can be adjusted according to the actual animal sample and experimental data to match the production. The exhaust hole 35 is set to guide the airflow to avoid contamination of the sample by the airflow containing the inducing smell through the swab cotton ball 32. The inducing smell of the porous rattan stick 25 can be set in various ways, so it needs to be avoided. If the smell composition is inert and low in concentration, it may only slightly contaminate or have no significant effect on the target object. If the substance in the inducing smell reacts with the target detection object in the saliva, such as hormones, pathogens, metabolites, etc., it will have an impact. The exhaust hole 35 is set to avoid this impact, and when the installation cover 28 is installed on the outside of the branch pipe 1, the inside of the support surface of the connecting pipe 29 leaves a certain space for the adsorption pipe 17 and the outer cover 21.
