Abstract
A drug delivery device may include sterile needle covered by removable a sterility preserving protector. The device optionally includes skin contact surface and a needle protector for preventing a stick hazard upon removal of the skin contact surface from an injection site or angle without Removing completely. Optionally, the needle protector may include a shield that interferes with replacement of the needle protector. In some embodiments, the needle cover may interfere with deployment of the needle protector.
Claims24
An injector with a needle stick protector comprising:
- a frame having a skin contact surface and defining an aperture in said skin contact surface;
- a needle having a sharp tip configured to advance through said aperture;
- a needle protector removably mounted over said needle;
- and
- a stick protector movably attached to said frame and biased against said needle protector, the stick protector being movable into a shielding position upon removal of the needle protector, blocking exposure of the sharp tip and preventing the needle from deploying.
A needle protection system for an autoinjector comprising:
- a frame including a skin contact surface having an aperture;
- a sterile needle including a sharp tip on a distal portion thereof, a connection between said needle and said frame defining a pathway of movement for advancing said tip through said aperture;
- a needle protector removably attached to said needle, said needle protector being removable from said needle along a trajectory defined by sliding of said needle protector along an axis of said distal portion of said needle;
- and
- a shield connected to said frame, the shield being movable between a deployed position blocking said pathway and said trajectory, an open position clearing said pathway and said trajectory and a primed position blocking said trajectory and clearing said pathway.
