Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry, in particular to a cow tail fixing device used for blood sampling from cow tail vein. Background Art

[0002] In the vast fields of veterinary medicine, biological research and animal husbandry, blood sampling from the tail vein of cattle is a vital animal medical practice, which plays an irreplaceable role in accurately diagnosing diseases, monitoring treatment effects and evaluating the nutritional status of animals. However, due to the deep location of the tail vein of cattle and the large size and strong strength of cattle, this operation is difficult.

[0003] The traditional method of collecting blood from the tail vein of cattle mainly relies on the experience and skills of veterinarians and staff, and usually requires two or more people to work together, one person is responsible for restraining the cattle, and the other is responsible for collecting blood. This method not only consumes a lot of human resources, but also the blood collection process may become extremely difficult if the cattle do not cooperate, and may even cause injuries to personnel or unnecessary harm to cattle.

[0004] With the continuous advancement of technology, some auxiliary tools have emerged in the market, such as horn bands and restraining frames, which are designed to improve the efficiency and safety of blood collection from the tail vein of cattle. These tools can indeed improve the efficiency of blood collection from cattle to a certain extent and reduce the difficulty of operation for staff. However, they still have some problems that cannot be ignored. For example, the design of some fixing devices is too complicated, which not only takes up valuable space resources, but also is very cumbersome to operate. In addition, the size of these devices is often difficult to adjust and cannot adapt to cattle of different sizes and ages. The cumbersome operation process often makes the restraining process longer and more difficult, thereby increasing the pressure and discomfort of cattle. In addition, some fixing devices are not stable enough when fixing the tail of cattle, which can easily cause cattle to struggle and shift, which not only affects the accuracy of blood collection, but also may cause additional pain to cattle. Therefore, how to reduce the stress response and discomfort of cattle while ensuring the efficiency and safety of blood collection has become an urgent problem to be solved.

[0005] There is no effective solution to the problems in the related technology, such as the complexity of the oxtail fixing device, the difficulty in adjusting the fixing size which limits its use, the long time it takes to secure the oxtail, and the loose fixation of the oxtail.
