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 needle position and a second needle position, in the first needle position the needle is contained within the housing, in the second needle position at least a portion of the needle extends from the distal end portion of the housing;
an energy storage member disposed within the housing, the energy storage member configured to produce a force to move the needle from the first needle position to the second needle position;
an actuator including a first actuation member disposed within the housing and a second actuation member coupled to the distal end portion of the housing, the actuator configured to actuate the energy storage member when the first actuation member is moved within the housing; and
a safety lock movably coupled to the distal end portion of the housing, the safety lock including a protrusion configured to extend through an opening defined by the second actuation member and engage a portion of the first actuation member to limit movement of the first actuation member.

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.

9. 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 to an injection position in which a portion of the needle is disposed outside of a distal end portion of the housing; an actuator coupled to the distal end portion of the housing, the actuator configured to actuate the energy storage member when the actuator is moved relative to the housing, the actuator including a surface defining a first opening and a second opening, a portion of the needle being disposed through the second opening when the medicament injector is in the injection position; and a safety lock configured to be movably coupled to the distal end portion of the housing, a portion of the safety lock configured to be disposed through the first opening to limit movement of the actuator relative to the housing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 22)

16. 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 to an injection position in which a portion of the needle is disposed outside of a distal end portion of the housing; a first actuation member configured to actuate the energy storage member when moved within the housing between a first position and a second position, the first actuation member including a retention portion configured to engage a portion of the housing to limit movement of the first actuation member; and a second actuation member coupled to the distal end portion of the housing, a portion of the second actuation member configured to engage the retention portion of the first actuation member to disengage the retention portion from the portion of the housing when the second actuation member is moved relative to the first actuation member. - View Dependent Claims (17, 18, 19, 20, 23)
