Problems solved by technology

The application of living Phnom Penh leeches in Guangxi has been used since ancient times, and it can be used for skin flaps, skin grafts or other tissues that suffer from impaired venous circulation. However, the existing leech breeding techniques are based on outdoor field cultivation or ordinary indoor water tanks. Breeding is the main method, and the live leeches obtained from farming will carry some pathogenic bacteria, so the obtained live leeches cannot be directly used in medical treatment

[0003] In order to use the live leeches obtained from farming for medical treatment, it is necessary to disinfect the live leeches according to the user's own knowledge, which leads to the use of live leeches for medical treatment The quality and safety of leeches are not uniform, and there are potential safety hazards, which makes it difficult to promote the medical application of live leeches
