SAFETY SYSTEM FOR SYRINGE

摘要

A Safety system for a syringe having a housing, a syringe carriage slidably mounted within the housing and a syringe socket defined within the syringe carriage. The syringe carriage is able to assume an injection position and a retracted position. The retracted position being the safety position following injection. The syringe carriage may also be capable of assuming a cocked position for forced insertion. A retraction spring includes a loaded position and a released position. A retractable catch or frangible seat operates to release the retraction spring to withdraw the syringe needle into the housing. A spring biases the syringe carriage to the extended position and a latch selectively retains the syringe carriage in the cocked position. A cover permanently lockable can close the housing after use.
