Description

Technical Field

[0001] The invention relates to the technical field of blood sampling equipment, and in particular to a multifunctional blood sampling device and method for animal husbandry and veterinary medicine. Background Art

[0002] The multifunctional blood collection device for animal husbandry and veterinary medicine is an important invention in the field of animal husbandry disease prevention and blood collection technology. The birth of this device stems from the demand for efficient and stable blood collection tools in animal husbandry and veterinary practice. Traditional blood collection methods are often time-consuming and labor-intensive, and it is difficult to ensure the accuracy and safety of blood collection. In order to meet this challenge, researchers have developed a multifunctional blood collection device to improve blood collection efficiency, reduce the labor intensity of veterinarians, and ensure the stability and safety of the blood collection process. These devices not only have automatic blood collection functions, but can also adjust the amount of blood collected according to actual needs, avoiding the tediousness of manual observation of scale lines. In addition, they are also easy to operate and easy to replace blood collection components, which greatly improves the efficiency and convenience of animal husbandry and veterinary work.

[0003] After searching, the invention patent of Chinese patent number CN115553772A discloses a multifunctional blood sampling device and method for animal husbandry and veterinary medicine, including a blood sampling tube, a connector, a needle, a blood drawing component, a limit component and a scale line. The blood sampling tube is provided with a blood drawing component, and the blood drawing component is provided with a limit component inside. The outer wall of the bottom end of the blood sampling tube is fixed with a connector, the outer wall of the connector is plugged with a needle, and the outer wall of the blood sampling tube is provided with scale lines. The blood drawing component is provided in the present invention, which is convenient for driving the piston to move by a rotating motor, thereby realizing automatic blood collection. The veterinarian only needs to hold the blood sampling tube with one hand to collect blood. The blood collection is relatively stable, the blood collection efficiency is improved, and the labor intensity of the veterinarian is effectively reduced. It is more practical and complete. The limit component is provided to adjust the height of the limit plate according to the amount of blood to be collected. When the limit plate contacts the limit ring, the piston cannot move, and the blood collection is completed. There is no need to collect blood while looking at the scale line, which further improves the efficiency of blood collection. Compared with the prior art, the invention patent with Chinese patent number CN115553772A aims to solve the defects of the currently used blood sampling devices, namely, the functions are relatively single, the blood sampling effect is relatively poor, the labor intensity of veterinarians is increased, and the blood sampling efficiency is reduced.
