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 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;
a base coupled to the distal end portion of the housing, the base configured to actuate the energy storage member when the base is moved relative to the housing, the base defining an opening through which the needle is disposed when the needle is in the second needle position; and
a safety lock moveably coupled to the distal end portion of the housing such that the safety lock moves in a direction nonparallel to a longitudinal axis of the needle between a first safety lock position and a second safety lock position, the safety lock configured to prevent movement of the base when the safety lock is in the first safety lock position.

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.

11. An apparatus, comprising:
-
a housing having a proximal end portion and a distal end portion; a medicament container disposed within the housing; an energy storage member disposed within the housing, the energy storage member configured to produce a force to move the medicament container to an injection position; a needle fluidically coupled to the medicament container when the medicament container is in the injection position, a distal end of the needle extending from the distal end portion of the housing when the medicament container is in the injection position; a base movably coupled to the distal end portion of the housing, the base defining an opening through which the needle is disposed when the medicament container is in the injection position; and a safety lock moveably coupled to the distal end portion of the housing, the safety lock having an elongated portion disposed between a shoulder of the housing and a shoulder of the base to prevent movement of the base when the safety lock is in a first position, the elongated portion removed from between the shoulder of the housing and the shoulder of the base when the safety lock is in a second position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An apparatus, comprising:
-
a housing; a medicament container disposed within the housing; an energy storage member disposed within the housing, the energy storage member configured to produce a force to move the meth saner from a first container position to a second container position; a needle fluidically coupled to the medicament container when the medicament container is in the second container position, a portion of the needle extending from a distal end portion of the housing when the medicament container is in the second container position; a base movably coupled to the distal end portion of the housing, the base defining an opening through which the needle is disposed when the medicament container is in the second container position; a safety lock moveably coupled to the distal end portion of the housing, the safety lock in contact with the base to limit movement of the base when the safety lock is in a first position, the safety lock spaced apart from the base when the safety lock is in a second position; and a cover removably coupled to the distal end portion of the housing, the cover surrounding the safety lock and the base. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
