A ring with the ability to diagnose sexually transmitted diseases like syphilis, gonorrhea, chlamydia and trichomoniasis was designed by the Mexican Ernesto Rodríguez Leal. The portable medical device called Hoope is a ring that is placed in the thumb, contains a disposable cartridge with a retractable needle for single use and sends the data to a smartphone in less than a minute.
The ring functions as a home diagnostic tool that distributes blood into four microfluidic channels. There are antigens specifically synthesized to catch antibodies for each of the diseases, their interaction functions as a lock and key mechanism. If antibodies for any of the conditions exists, the antigens trap them and produce an electrochemical reaction. After, these data is wirelessly transmitted to a smartphone or tablet, where an app gives results in less than a minute
