Automatic injection device

摘要

Automatic injection device includes a housing, a syringe, a plunger, and a syringe carrier. The housing includes a barrel. The barrel includes an elongated window to allow viewing of contents inside the housing. The syringe is disposed within the housing and has a reservoir. The plunger is at least partially disposed within the syringe and includes a visual indicator. The syringe carrier is disposed within the housing and configured to contain the syringe and displace the syringe within the housing between a first position and a second position. The syringe carrier has a first opening and a second opening. The first opening is configured to align with the window and the reservoir when the syringe carrier is in the first position, and the second opening is configured to align with the window and the visual indicator when the syringe carrier is in the second position.

主权项

1. An automatic injection device comprising:
a housing component having a first end, a second end, and an elongated window disposed between the first end and the second end to allow viewing of contents inside the housing; a firing body having a first end, a second end, and a mating tab protruding from an exterior surface thereof between the first end and the second end of the firing body, the first end of the firing body mateable to the second end of the housing component; a syringe disposed within the housing component and having a first end, a second end, and a reservoir between the first end and the second end; a plunger at least partially disposed within the syringe and comprising a visual indicator on a portion of the plunger; a syringe carrier disposed within the housing component and having a first end and a second end, the syringe carrier configured to contain the syringe and displace the syringe within the housing component between a first position and a second position, the syringe carrier having a first opening proximate the first end of the syringe carrier and a second opening proximate the second end of the syringe carrier and aligned with the first opening along a length of the syringe carrier, the first opening configured to align with the window and the reservoir when the syringe carrier is in the first position, and the second opening configured to align with the window and the visual indicator when the syringe carrier is in the second position; and a removable actuator cap having a receptacle sized and shaped to cooperatively engage the mating tab protruding from the exterior surface of the firing body.
