DEVICES, SYSTEMS AND METHODS FOR MEDICAMENT DELIVERY

摘要

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.

主权项

1. 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 distal end portion of the housing.
