Medicament delivery device with alignment mechanism
First Claim
Patent Images
1. A medicament delivery device, comprising:
- a case configured to contain a syringe or cartridge having a needle, the needle being configured to extend through a geometric center of a distal face of the case;
a trigger button;
a plurality of projections movable relative to the case between an extended position in which distal ends of the projections extend beyond the distal face of the case and a retracted position in which the distal ends of the projections are substantially co-planar with the distal face, each projection being offset from the geometric center of the distal face; and
a locking mechanism operably coupled to the trigger button and the plurality of projections, wherein the locking mechanism locks the trigger button when at least one of the projections is not in the retracted position,wherein each projection is extendable and retractable independently of other projections of the plurality of projections, andwherein the projections are disposed in an alignment mechanism removably coupled to the case.

Abstract
Described is a medicament delivery device having a case and a plurality of projections movable relative to the case between an extended position in which distal ends of the projections extends beyond a distal face of the case and a refracted position in which the distal ends of the projections are substantially co-planar with the distal face.

11. A medicament delivery device, comprising:
-
a case configured to contain a syringe or cartridge having a needle, the needle being configured to extend through a geometric center of a distal face of the case; a plurality of projections moveable relative to the case between an extended position in which distal ends of the projections extend beyond the distal end face of the case and a retracted position in which the distal ends of the projections are substantially co-planar with the distal end face, each projection being offset from the geometric center of the distal face; and wherein the plurality of projections are distributed around a needle opening provided in the distal end face of the case, wherein each projection is extendable and retractable independently of other projections of the plurality of projections;
.wherein each of the projections is biased by a spring toward the extended position, and wherein each of the projections is biased by a different spring. - View Dependent Claims (12, 14, 15, 16, 17)

13. A medicament delivery device, comprising:
-
a case configured to contain a syringe or cartridge having a needle, the needle being configured to extend through a geometric center of a distal face of the case; a plurality of projections moveable relative to the case between an extended position in which distal ends of the projections extend beyond the distal end face of the case and a retracted position in which the distal ends of the projections are substantially co-planar with the distal end face, each projection being offset from the geometric center of the distal face, wherein the plurality of projections are distributed around a needle opening provided in the distal end face of the case, wherein each projection is extendable and retractable independently of other projections of the plurality of projections, and wherein the plurality of projections includes three projections spaced 120°
relative to each other.
