An injection device which includes a container constructed and arranged to contain a medicament, a medicament disposed within the container, a seal constructed and arranged to seal the medicament in the container, and a hypodermic needle. The hypodermic needle has a tubular, elongated, generally cylindrical wall defining an internal longitudinal bore extending longitudinally through the cylindrical wall along a longitudinal axis. The cylindrical wall forms a forward end defining a forward opening of the bore and a rearward end defining a rearward opening of the bore, the cylindrical wall having a laterally facing opening spaced closer to the rearward opening of the longitudinal bore than the forward opening of the longitudinal bore. The longitudinal bore is restricted at a position between the rearward opening and the laterally facing opening. The forward end has a point constructed and arranged to pierce an individual's flesh, the rearward end having a point constructed and arranged to pierce the seal so that the rearward opening and the laterally facing opening establish fluid communication with the medicament to enable the medicament to be dispensed through the bore and into the individual's flesh.

Injection device having anti-coring needle

A hypodermic needle comprising a tubular, elongated, generally cylindrical wall defining an internal longitudinal bore extending longitudinally therethrough along a longitudinal axis, The longitudinal bore has forward and rearward openings. The cylindrical wall is constructed and arranged to form a forward pointed end and a rearward pointed end. The rearward pointed end is defined by an annular end surface forming the rearward end of said cylindrical wall. The rearward pointed end terminates in a rearwardmost point lying in an imaginary plane disposed perpendicularly to the longitudinal axis. The annular rearward end surface defines an imaginary plane inclined with respect to the imaginary plane perpendicular to the longitudinal axis. The cylindrical wall has a laterally facing opening spaced from the rearward opening of the longitudinal bore, and the longitudinal bore is restricted at a position between the rearward opening and the laterally facing opening.

Anti-coring needle

An injection device includes a generally tubular outer body and a medicament cartridge assembly carried within the outer body. The cartridge assembly includes a glass container, a charge of medicament disposed within the glass container, iii) a plunger member rearwardly confining the medicament, and iv) a seal for sealing the forward portion of the glass container. A needle has a rearward end disposed proximate the seal, with the seal and needle being movable with respect to one another. A rigid needle cover member is normally maintained in an inoperative position and is movable relative to said body to a protective position wherein the needle cover member extends forwardly to cover the forward end of the needle. A releasable spring is releasable in response to a predetermined actuating procedure to drive a collet member forwardly within the outer body and thereby enable i) the cartridge assembly to move relative to the needle so that the rearward end of the needle pierces the seal to establish communication with the medicament, ii) the needle to move with respect to the body so that the needle projects outwardly from the forward end of the body, and iii) the needle cover to move relative to the body from the inoperative position to the protective position so that the needle cover member extends beyond the forward end of the needle.
