Medical injector
First Claim
1. A device, comprising:
- a housing including a planar side wall defining a portion of a boundary of a medicament reservoir having a substantially rectangular cross-sectional shape within a plane substantially normal to a longitudinal axis of a liquid dispensing needle;
a plunger disposed at least partially within said medicament reservoir and movable between a first position and a second position;
a liquid dispensing needle coupled to said plunger, said needle including a channel configured to be in fluid communication with said medicament reservoir, said needle contained within said housing when said plunger is in said first position, at least a portion of said needle disposed outside of the housing when said plunger is in said second position; and
a spring disposed within the housing, the spring configured to bias the plunger.
