Abstract
Described is a medicament delivery device (1) comprising a case (2) adapted to hold a container (3) of a medicament, a drive mechanism (5) adapted to expel the medicament from the container (3), and a trigger button (6) disposed on the case (2) and operably coupled to the drive mechanism (5). The trigger button (6) has a concave position and a convex position. Movement of the trigger button (6) from the convex position to the concave position causes activation of the drive mechanism (5).
Claims18
A medicament delivery device comprising:
- a container of a medicament, the container including a needle;
- a case adapted to hold the container, wherein the container is slidably disposed in the case and moves between a first position in which the needle is substantially covered by the case and a second position in which the needle extends beyond a distal end of the case;
- a drive mechanism adapted to expel the medicament from the container;
- a trigger button disposed on the case and operably coupled to the drive mechanism, the trigger button having a concave position and a convex position, wherein movement of the trigger button between the convex position and the concave position causes activation of the drive mechanism;
- and
- an interlock member telescopically coupled to the case and translatable between an extended position relative to the case and a retracted position relative to the case, wherein the interlock member is operably coupled to the trigger button.
A medicament delivery device comprising:
- a case adapted to hold a container of a medicament;
- a trigger button disposed on the case, the trigger button having a convex position and a concave position, the trigger button configured to move between the convex position and the concave position;
- a drive mechanism operably coupled to the trigger button, the drive mechanism configured to expel the medicament from the container in response to the trigger button moving between the convex position and the concave position;
- and
- an interlock member telescopically coupled to the case and translatable between an extended position relative to the case and a retracted position relative to the case, wherein the interlock member is operably coupled to the trigger button.
A medicament delivery device comprising:
- a case adapted to hold a container of a medicament;
- a drive mechanism adapted to expel the medicament from the container, wherein the drive mechanism includes a plunger adapted to apply a force on a stopper in the container and a drive spring adapted to apply a force on the plunger;
- a trigger button disposed on the case and operably coupled to the drive mechanism, the trigger button having a concave position and a convex position, wherein movement of the trigger button between the convex position and the concave position causes activation of the drive mechanism;
- and
- an interlock member telescopically coupled to the case and translatable between an extended position relative to the case and a retracted position relative to the case, wherein the interlock member is operably coupled to the trigger button.
