Reusable Syringe / Syringe

As is known to us all, disposable syringes have a good effect to prevent
the spread of AIDS in Africa, but at the same time, we neglect a point that
a large number of abandoned syringes have caused irreparable damage
to the original beauty of the African continent. Different from the traditional
syringe, we make barrel and piston not in contact with the liquid, so the
no-longer syringe we designed not only can save materials, improve the
utilization rate, more importantly, also protect the ecological environment
Africa area.
