Mink venous blood collection method

Abstract

The invention provides a mink venous blood collection method which includes the steps: fixing a mink, disinfecting a manubrium and the periphery of the manubrium of the mink, taking the tail end of the manubrium as a datum point, forming an angle of 30-45 degrees between the manubrium and a sternal bar and taking the right centripetal position of a body median line as a blood collection site; stabbing the blood collection site by a blood collection needle, and enabling blood to flow into the blood collection needle if stabbing an anterior vena cava after repeated needling tests; connecting a blood collection tube and collecting the blood. According to the mink venous blood collection method, the blood is collected at the position of the anterior vena cava of the mink, a traditional toenailcutting and heart blood collection method is replaced, irritation and injury to the mink caused by the blood collection process are reduced, the requirement of animal welfare is met, blood collectionefficiency and blood quality are improved, application of a blood sample in an animal experiment research process is more facilitated, the experimental requirement of the blood sample is met, and theblood sample can be more effectively applied to the field of physiological and biochemical research.

Description

technical field [0001] The invention relates to the technical field of blood collection, in particular to a method for collecting mink vein blood. Background technique [0002] The body of mink is slender, the male body length is 38-42 cm, the tail length is 20 cm, and the body weight is 1.6-2.2 kg, while the female is smaller. The body hair is yellowish brown, with white spots on the jaws, the head is small, the eyes are round, and the ears are semicircular, slightly higher than the head and inclined to the front, and cannot swing. The neck is thick and short, the limbs are thick, the forelimbs are slightly shorter than the hind limbs, there are webs between the fingers and toes, the webs between the rear toes are more obvious, and there are fleshy pads on the soles of the feet. The tail is slender and the hair is fluffy. Mainly nocturnal and eats small rodents, but also mole crickets, frogs and fish. [0003] In view of the fact that the mink is covered with fur, small ...

Problems solved by technology

[0003] In view of the fact that the mink is covered with fur, small in size and flexible in movement, it is difficult to capture and fix it, and it is even more difficult to collect blood. In the scientific research and experiment of mink, blood collection is required many times. In clinical practice, toenail clipping or heart blood collection are often used. Both methods have many disadvantages. Toenail clipping and blood collection cannot guarantee sterility. Cardiac blood collection is more harmful to the heart, and it is also easy to injure other organs, causing internal bleeding and affecting normal growth. Usually, the needle punctures the heart and liver and causes bleeding. die of too much

Moreover, neither of the two methods can collect blood for multiple times in a row. In this way, many researchers have locked the blood collection object in the vein of the mink. Considering that a large amount of blood is needed for scientific research, ordinary small veins cannot meet this requirement. Requirements, need to find a vein that can provide sufficient blood and convenient and easy blood collection method to replace toenail clipping and heart blood collection
