ABSTRACT:
A low cost safety sterile cartridge injector apparatus comprising an injector and a safety needle sheath having elements which promote facile assembly and disassembly. An embodiment is disclosed which incorporates an integral needle hub and safety sheath which is displaced to protectively cover a medical needle after use. The sheath also incorporates patterns of rachet teeth which cooperate with a holder portion of the injector to lock a sterile cartridge in place for use in a medical procedure and to release the cartridge for facile disposal when the sheath is displaced to cover and protectively shroud the needle after use. Through this process, need for rotary collars to capture and hold the cartridge in place during use is eliminated, reducing injector cost and apparatus assembly steps and time.
