Problem being addressed
HIV/AIDS is a devastating epidemic that affects millions of people around the globe. Circumcision has been shown to reduce HIV/AIDS transmission by up to 60%.(citation needed) There is a need for low-cost and easy-to-use technologies that enable health care providers with limited training to perform the procedure.
Detailed description of the solution
The ShangRing is a new circumcision tool that helps health care providers with limited training to perform circumcision. There is no cutting or suturing of the foreskin. The device consists of two parts (rings). The outer ring applies constant pressure to the foreskin, which leads to the foreskin’s removal. The device must remain on the penis for 5-7 days.
