Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to an animal oral fluid sampling device for animal epidemic diseases. Background Art

[0002] The Animal Oral Fluid Sampling Device for Animal Diseases is a medical device or tool specifically designed to collect oral fluid from animals. It is primarily used for the detection, diagnosis, and research of animal diseases. By collecting oral fluid samples, animals can be tested for viral, bacterial, or other pathogenic infections, such as rabies, foot-and-mouth disease, and swine fever.

[0003] Patent publication number CN221205489U relates to the technical field of sampling devices. The patent provides an animal oral fluid sampling device, comprising a main body block with a handle welded to the main body block for holding. The device allows the animal's mouth to be held open during sampling, preventing bites to personnel and improving overall safety. After the animal's mouth is held open, oral fluid can be conveniently collected, completing the initial sampling. When subsequent sampling is required, the sample can be directly taken from the collection box. This facilitates quick sampling and eliminates the risk of bites when using a sampling device. Currently, sampling requires holding the animal's mouth open and then using a sampler. During the sampling process, one hand is required to sample while the other hand controls the sampler to hold the animal's mouth open, resulting in reduced stability. If the spreader becomes detached from the animal's mouth, a safety hazard could occur.

[0004] In the above patent, the animal's mouth is opened by improvement, which can prevent the animal from biting the staff and improve the overall safety performance. However, it is difficult to fix the animal to keep it still when sampling the liquid in the animal's mouth, which can easily cause the animal to move around during sampling and pose a danger to the staff.

[0016] The present invention provides an animal oral fluid sampling device for animal disease detection. It has the following beneficial effects:

[0017] (1) This invention uses two rubber blocks to move against the upper and lower jaws of the animal, respectively, to keep the mouth open, making it easier for the sampling device to enter and improving operational efficiency. At the same time, the rubber material is soft, which can reduce damage to the animal's mouth and avoid discomfort or damage during sampling. The top guard can move to block part of the field of vision when sampling oral fluid, reducing the animal's perception of the external environment, relieving its tension, thereby reducing stress reactions and making the animal more cooperative with sampling. At the same time, the use of the top guard can reduce the need for additional fixation of the animal, simplify the operating steps, and save time and manpower.

[0018] (2) This invention can effectively control the movement of the animal's head by moving the clamp rod, preventing it from struggling or swinging, and ensuring that the sampling process proceeds smoothly. At the same time, after the head is fixed, the operator can use the sampling device more accurately, reducing operation time and improving efficiency. After the animal is fixed, the collection drawer can be moved and pushed out to accurately collect oral fluid, avoiding sample contamination or omission caused by animal movement, thereby improving detection accuracy. At the same time, after the animal is fixed, the operator can focus more on sampling without being distracted by controlling the animal, thereby improving efficiency.

[0019] (3) This invention makes the process of gradually pushing out and opening the collection drawer smoother, avoiding sudden movements that might scare the animals and reducing their stress response. At the same time, the operation of pushing out and opening the collection drawer is more orderly, reducing the possibility of operational errors and repeated sampling, and improving overall efficiency.

[0020] (4) This invention limits the collection box by contacting the inclined rod with the limiting block to ensure that the next sampling device remains stable during operation, avoiding sampling errors caused by shaking or offset. At the same time, preventing the collection box from moving excessively can reduce the risk of accidental collision or equipment damage during operation, thereby protecting the safety of operators and animals.
