Nowadays thousands of people were infected with diseases like HIV, HBV, etc. through used injectors, especially in some poor districts. In addition, how to deal with billions of abandoned injectors safely and eco-friendly is also a big issue to all of us.
The material of the injector is changed into syringe. It is made of a synthetic fiber with low hygroscopicity, which has enough hardness in the normal condition and will become soft in 10 minutes once contact with liquid. When the injector becomes dry, it will maintain the deformation and can not be used again. Additionally, the biodegradable synthetic fiber is eco-friendly after abandoned.
