Description

A blood collection device for African swine fever virus samples in large-scale pig farms

technical field

The invention relates to the technical field of blood collection, and more particularly, the invention relates to a blood collection device for African swine fever virus samples in large-scale pig farms.

Background technique

At present, the risks and challenges faced by farms are very large, because there are many epidemic diseases. Since the African swine fever virus was first discovered in my country in August 2018, it has spread extremely rapidly, and it has appeared in many provinces and regions. At present, the detection of African swine fever virus mainly adopts laboratory methods, which is inseparable from the preparation of experimental samples. Since African swine fever is a DNA virus, we generally extract the DNA from the sample. After a certain system ratio, after polymerase chain reaction (PCR), nucleic acid electrophoresis is performed to observe whether there is a bright band corresponding to its position. Determine whether it contains African swine fever virus.

For samples, they can be divided into two types: blood samples and tissue and organ samples. The preparation of blood samples is relatively simple. The collected blood is put into a centrifuge tube, and the plasma part is collected by centrifugation, and then a commercial blood DNA extraction kit is used. Just do the extraction.

Common pig blood collection methods are: ear vein blood collection and anterior vena cava blood collection. Both of them need to be stabilized before blood collection. The former is relatively easier to operate, while the latter is more troublesome. According to the actual situation, if the auricular vein of the pig is clearly visible, and the pig body is larger and the blood vessels are thicker, blood is collected from the ear marginal vein, otherwise, the anterior vena cava is used for blood collection. When the existing ear vein blood collection is used, due to its simple structure, it is easy to be inconvenient to collect blood due to the turbulent movement of the pig, the blood collection risk is high, and it is also easy to cause blood coagulation, and the use effect is poor. .
