The day when all syringes are single-use many not be far off as indicated by the One-Time Injection Needle. The One-Time Injection Needle is the second one-time-use syringe to be featured on Trend Hunter and was designed by Gyeongwan Koo.
The One-Time Injection Needle is designed to help diseases from spreading via syringe sharing. Syringe sharing is typically a problem of drug addicts in the first world, but it is often an issue in the medical offices of the third world. A lack of funds and proper training can be a deadly combination as the same syringe is used multiple times in rural clinic. Koo's redesign incorporates a piece of hard elastic that stops the needle from drawing after a second use. The word "used" also appears along the syringe in case someone needs an overt warning not to use the needle again.
