[0002] Blood is an opaque red liquid flowing in the heart and blood vessels. Blood contains various nutrients and stores human health information. Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, and bone marrow cytology. Detection, blood type identification and cross-matching experiments can detect the hematological characteristics of common blood diseases; when patients undergo examination in the hospital, they often need to collect blood for laboratory tests; some of the following contents can be detected through blood testing, alanine amino Transferase, hepatitis C virus antibody, HIV antibody, and syphilis tests, etc.; when taking blood samples from patients, it is necessary to manually pull out the tail needle of the blood collection needle and insert it into the next set of blood collection tubes. Manual operation makes blood collection easier. The tail of the needle will cause harm to medical staff; unskilled medical staff need to spend more time switching blood collection tubes, which will greatly increase the exposure time of the tail needle of the blood collection needle in the air, and germs and impurities in the air are easy to attach to the blood collection needle On the tail needle, which affects the accuracy of blood testing
