SID Technologies is developing intradermal devices aiding healthcare workers in performing intradermal injections. The goal is to provide an alternative, easier to learn method of intradermal drug delivery to the Mantoux technique, in order to expand the population of healthcare workers who may deliver drugs intradermally. This, in tum, is expected to spare valuable doses of expensive, short-supply vaccines such as rabies, thereby stretching supplies and reaching more patients. A successful 10 delivery technology could also catalyze novel approaches for existing vaccines that could be used more widely, less expensively, and potentially more effectively through the 10 route. Auto Disable Intradermal adapter (AD 10 adapter) is intended for safe intradermal injection in conjunction with AD syringes. When used with AD syringes the AD ID adapter will prevent the potential reuse of the 10 device with a new syringe minimizing the occupational acquisition of patient infections as well as a potential for cross contamination of patients. The AD 10 adapter is envisioned as a single molded plastic part. The manufacture of the AD 10 adapter does not require any specialized technologies. The adapter could be introduced into developing world practice in a few years Immediately reducing the vaccination costs.
