Problems solved by technology

[0002] Vacuum blood collection technology is an advanced blood collection technology today, and it is very popular in the medical field. Vacuum blood collection devices replace disposable syringes for blood collection. Because of its advantages of simple operation, less pain for patients, high work efficiency and large blood collection volume, vacuum blood collection technology is in It is very popular clinically. In the actual nursing practice in recent years, the nurses are not particularly familiar with the vacuum blood collection device and cannot skillfully use the vacuum blood collection technology. It is necessary to invent a blood collection tool that can be used flexibly and is easy to operate. Vacuum blood collection has the advantages of sterility, environmental protection, and fast speed. The traditional blood collection device is complicated to operate and has a single function, which cannot meet the problem of large blood collection volume in major hospitals.
