Abstract

An autoinjector includes a case, a door hingedly coupled to the case and having an open position and a closed position, a plunger slidably disposed in the case, and at least one drive spring applying a biasing force on the plunger relative to the case, wherein the door is operably coupled to the plunger, and wherein rotation of the door from the closed position to the open position moves the plunger from a distal position in the case to a proximal position in the case and compresses the at least one drive spring.

First claim

1 . (canceled)

2 . An autoinjector comprising:
a housing configured to receive a syringe assembly; a door coupled to the housing and adjustable from a closed position to an open position for providing access to a support surface configured to support the syringe; and a linkage that pivotably couples the door to the housing, wherein the autoinjector is configured to support the syringe assembly on the support surface in a manner such that a distal portion of the syringe assembly extends from a distal end of the housing, and wherein the autoinjector is push-actuatable for expelling a dose of a medicament from the syringe assembly when the syringe assembly is positioned on the support surface and the autoinjector is pressed against an injection site.

3 . The autoinjector of claim 2 , wherein a distal end of the door substantially aligns with the distal end of the housing when the door is in the closed position.

4 . The autoinjector of claim 2 , wherein the door comprises a viewing window that overlaps at least a portion of the syringe assembly when the syringe assembly is supported on the support surface and when the door is in the closed position.

5 . The autoinjector of claim 4 , wherein the viewing window has an elongate shape.

6 . The autoinjector of claim 4 , wherein the viewing window is centrally positioned with respect to the door.

7 . The autoinjector of claim 2 , wherein the autoinjector comprises one or more gripping features.

8 . The autoinjector of claim 2 , wherein the housing has an elongate shape.

9 . The autoinjector of claim 2 , wherein the housing has a substantially rectangular shape.

10 . The autoinjector of claim 2 , wherein the autoinjector is a reusable autoinjector.

11 . The autoinjector of claim 2 , wherein the support surface extends along a length of the housing.

12 . The autoinjector of claim 2 , further comprising the syringe assembly.

13 . The autoinjector of claim 12 , wherein the syringe assembly comprises a body containing the medicament, a needle coupled to the body, and a removable cover that is configured to cover the needle prior to use of the syringe assembly.

14 . The autoinjector of claim 12 , wherein the syringe assembly has an elongate shape.

15 . The autoinjector of claim 2 , wherein a distal end of the door substantially aligns with the distal end of the housing when the door is in the closed position, and wherein the door comprises a viewing window that overlaps at least a portion of the syringe assembly when the syringe assembly is supported on the support surface and when the door is in the closed position.

16 . The autoinjector of claim 15 , wherein the viewing window has an elongate shape, and wherein the viewing window is centrally positioned with respect to the door.

17 . The autoinjector of claim 2 , wherein the housing has a substantially rectangular shape, and wherein the support surface extends along a length of the housing.

18 . The autoinjector of claim 17 , wherein the autoinjector comprises one or more gripping features.

19 . The autoinjector of claim 2 , further comprising the syringe assembly, wherein the syringe assembly comprises a body containing the medicament, a needle coupled to the body, and a removable cover that is configured to cover the needle.

20 . The autoinjector of claim 19 , wherein the syringe assembly has an elongate shape.

21 . The autoinjector of claim 19 , wherein the autoinjector comprises one or more gripping features.
