Abstract
This invention relates to a holder for use in combination with a pre-filled cartridge-needle unit, the holder comprising a hollow body sized for housing the cartridge-needle unit therein, and means for permitting the body to move axially relative to the cartridge-needle unit. In one preferred embodiment, the distal end of the body is elliptical in cross section and the proximal end of the body is circular in cross section. In another preferred embodiment, the body comprises a pair of cam slots at the distal end and a pair or retaining slots at the proximal end, the slots being sized to accept a circumferential ring on the cartridge-needle unit and positioned to hold the cartridge-needle units in use and safe positions. The holder is easier to use and manufacture and reduces the susceptibility of health care workers to accidental needle strikes.
