Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry blood sampling, and in particular to an automatic cattle tail blood sampling device and system. Background Art

[0002] In animal husbandry, the collection of animal blood samples is an important part of disease diagnosis, health monitoring and genetic research. For cattle, the tail vein is one of the commonly used blood collection sites. However, due to the deep tail vein of cattle and the large size of cattle, the cattle need to be restrained during manual blood collection, which increases the difficulty of operation. The traditional manual blood collection method is not only inefficient, but also has certain risks. Especially in the blood collection process of large animals such as cattle, manual blood collection not only causes a greater stress response to the animals, affecting their health and production performance, but may also lead to blood collection failure or sample contamination due to improper operation.

[0003] At present, there are some automatic blood collection devices on the market, but most of the equipment still has some shortcomings. First, most of the existing devices are complicated to operate, not easy to be fixed on the cow's tail, and need to be operated by professionals; second, most of the existing devices are of a single size, often unable to adapt to cattle of different sizes, resulting in animal struggles during blood collection, affecting the blood collection effect; third, due to the deep location of the cattle's tail vein, the existing blood collection needles are often difficult to accurately locate the vein, resulting in blood collection failure or multiple attempts to cause pain to the cattle; in addition, some automated blood collection devices have high manufacturing costs, which are not conducive to popularization in large-scale breeding. Some blood collection devices also have requirements for blood collection tubes and can only be used for blood collection tubes of certain specifications, which greatly limits the scope of application.

[0004] In view of the problems in the related technology, such as the blood collection device being complicated to operate and not firmly fixed, the blood collection device being unable to be adjusted according to the size of the oxtail, and the blood collection device being only suitable for some blood collection tubes and thus having limited use, no effective solution has been proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic oxtail blood sampling device and system to address the deficiencies in the prior art, so as to solve the problems existing in the related art, such as the blood sampling device is complicated to operate and is not firmly fixed, the blood sampling device cannot be adjusted according to the size of the oxtail, and the blood sampling device is only suitable for some blood sampling tubes and has limited use.
