Devices and methods for delivering medicaments from a multi-chamber container
First Claim
1. An apparatus, comprising:
- a housing;
a medicament container assembly disposed within the housing, the medicament container assembly containing a first substance and a second substance, the medicament container assembly including a first elastomeric member and a second elastomeric member, the first elastomeric member defining a portion of a first volume containing the first substance, a channel defined through the second elastomeric member;
an energy storage member configured to produce a force to move the first elastomeric member such that the first substance is conveyed from the first volume via the channel to produce a mixture of the first substance and the second substance within a second volume, the second volume defined at least in part by the second elastomeric member;
a mixing actuation member disposed within the housing, the mixing actuation member configured to actuate the energy storage member when moved from a first position to a second position;
a safety member removably coupled to a distal end portion of the housing, the safety member including an engagement portion configured to engage a distal end portion of the mixing actuation member such that when the safety member is being removed from the housing the mixing actuation member is moved from the first position to the second position; and
an actuator movably coupled the distal end portion of the housing, the actuator including a distal surface configured to be placed against a target, the distal surface defining an opening, the actuator configured to initiate delivery of the mixture of the first substance and the second substance through the opening after the safety member is removed from the housing and when the distal surface is pressed against the target.

Abstract
An apparatus includes a housing, a medicament container, and a movable assembly. The movable assembly includes a first movable member and a second movable member. The second movable member is configured to move relative to the first movable member to move the movable assembly from a first configuration to a second configuration. A distal end portion of the second movable member is configured to move a plunger disposed within the medicament container in a distal direction when the movable assembly is moved to the second configuration. The movable assembly is configured to move between a first position and a second position to move the medicament container within the housing between a first container position and a second container position.

13. An apparatus, comprising:
-
a housing having a distal end portion that defines an opening; a medicament container assembly disposed within the housing, the medicament container assembly containing a first substance and a second substance, the medicament container assembly including a first elastomeric member and a second elastomeric member, the first elastomeric member defining a portion of a first volume containing the first substance; an energy storage member configured to produce a force to move the first elastomeric member such that the first substance is conveyed from the first volume to produce a mixture of the first substance and the second substance within a second volume, the second volume defined at least in part by the second elastomeric member; a mixing actuation member disposed within the housing, the mixing actuation member configured to release the energy storage member such that the force is exerted upon the first elastomeric member when at least a portion of the mixing actuation member is rotated within the housing; a safety member coupled to the distal end portion of the housing, the safety member including an outer surface disposed outside of the housing and covering the opening, the safety member including a protrusion disposed within the housing, the protrusion configured to engage a portion of the mixing actuation member such that when the safety member is being removed from the housing, the portion of the mixing actuation member is rotated within the housing and the opening of the housing is exposed; and an actuator movably coupled to the distal end portion of the housing, the actuator configured to initiate delivery of the mixture of the first substance and the second substance through the opening when the actuator is moved relative to the housing and after the safety member is removed from the housing. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
