Devices, systems and methods for medicament delivery
First Claim
1. An apparatus, comprising:
- a housing having a distal end portion and a proximal end portion;
a needle configured to move between a first position and a second position, in the first position the needle is contained within the housing, in the second position at least a portion of the needle extends from the distal end portion of the housing;
an energy storage member having a first configuration and a second configuration, the energy storage member configured to produce a force when moved between its first configuration and its second configuration to move the needle from its first position to its second position;
an actuator configured to move the energy storage member from its first configuration to its second configuration, the actuator including a first actuation member disposed within the housing and a second actuation member coupled to the distal end portion of the housing; and
a locking member configured to be movably coupled to the distal end portion of the housing such that the locking member can be moved between a first position and a second position, the locking member including a protrusion configured to extend through an opening defined by the second actuation member and engage a portion of the first actuation member when the locking member is in its first position to prevent the actuator from moving the energy storage member to the second configuration.

Abstract
Apparatuses for automatic medicament injection and methods for manufacturing automatic medicament injectors are described herein. In some embodiments, an apparatus includes a housing, a needle, an energy storage member, an actuator, a locking member, and a needle guard. The needle is configured to move between a first position and a second position. In its first position, the needle is contained within the housing. In its second position, at least a portion of the needle extends from the housing. The energy storage member has a first configuration and a second configuration and is configured to produce a force when moving between its first configuration and its second configuration to move the needle from its first position to its second position. The actuator is configured to move the energy storage member from its first configuration to its second configuration. The locking member is movably coupled to the distal end portion of the housing such that the locking member can be moved between a first position and a second position. In its first position, the locking member is configured to engage the actuator to prevent the actuator from moving the energy storage member to the second configuration. The needle guard is removably coupled to at least one of the distal end portion of the housing or a base movably coupled to the distal end portion of the housing.

14. An apparatus, comprising:
-
a housing; a medicament injector movably disposed within the housing, the medicament injector including a medicament container and a needle; an energy storage member configured to produce a force to move the medicament injector such that a portion of the needle is disposed through a distal end surface of the housing at a first location when the energy storage member is moved from a first configuration to a second configuration; an actuator coupled to the distal end portion of the housing, the actuator configured to move the energy storage member from the first configuration to the second configuration when the actuator is moved relative to the housing, the actuator having a substantially planar surface configured to engage a body; and a locking member configured to be movably coupled to the distal end portion of the housing between a first position and a second position, the locking member including a protrusion configured to extend through the distal end surface of the housing at a second location such that the protrusion engages a portion of an actuation rod within the housing to limit movement of the actuator relative to the housing when the locking member is in its first position. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. An apparatus, comprising:
-
a housing; a medicament injector movably disposed within the housing, the medicament injector including a medicament container and a needle; a system actuator disposed within the housing, the system actuator configured to move the medicament injector within the housing when the system actuator is moved from a first configuration to a second configuration, the system actuator including; a gas container configured to contain a pressurized gas; a puncturer having a portion disposed apart from the gas container when the system actuator is in the first configuration, the portion being disposed within the gas container when the system actuator is in the second configuration; and a biasing member configured to urge the system actuator towards the second configuration when the biasing member is released; a base coupled to a distal end portion of the housing, the base configured to release the biasing member when the base is moved relative to the housing; and a safety lock movably coupled to the distal end portion of the housing, the safety lock configured to limit movement of the base relative to the housing when the safety lock is in a first position, the base configured to move relative to the housing when the safety lock is in a second position. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. An apparatus, comprising:
-
a housing; a medicament injector movably disposed within the housing, the medicament injector including a medicament container and a needle; an energy storage system disposed within the housing, the energy storage system configured to produce a first force to move the medicament injector in a distal direction such that a portion of the needle is disposed outside of a distal end portion of the housing when the energy storage system is moved from a first configuration to a second configuration; an actuator coupled to the distal end portion of the housing, the actuator configured to move the energy storage system from the first configuration to the second configuration when the actuator is moved relative to the housing; a locking member configured to be movably coupled to the distal end portion of the housing between a first position and a second position, the locking member configured to limit movement of the actuator relative to the housing when the locking member is in its first position; and a retraction spring configured to produce a second force to move the medicament injector in a proximal direction such that the portion of the needle is disposed within the distal end portion of the housing. - View Dependent Claims (32, 33, 34, 35, 36, 37)
