Devices, systems and methods for medicament delivery
First Claim
1. A method, comprising:
- placing an outer housing associated with a medical injector into contact with a body, the outer housing defining a status window and enclosing an inner housing, a piston member, an energy storage member, and an indicator, the piston member at least partially disposed within the inner housing and in contact with an elastomeric member disposed therein, the elastomeric member being in a first position associated with a pre-activation status prior to placing the outer housing into contact with the body, a first indication associated with the pre-activation status being viewable via the status window; and
actuating an actuator to release energy stored in the energy storage member to produce a force to move the piston member, the elastomeric member moving from the first position to a second position in response to movement of the piston member, the indicator configured to move with the piston member from a first indicator position to a second indicator position, the second indicator position being associated with a post-activation status, the indicator providing a second indication associated with the post-activation status viewable via the status window when the indicator is in the second indicator position.

Abstract
An apparatus includes a movable member and a valve coupled to the movable member. The movable member is configured to be disposed within a housing of a medical device and has a first end portion and second end portion. A portion of the first end portion is configured to define a portion of a boundary of a gas chamber. The first end portion defines an opening configured to be in fluid communication between the gas chamber and an area outside the gas chamber. The second end portion is configured to be coupled to a needle configured to deliver a medicament into a body. The valve is configured to selectively allow fluid communication between the gas chamber and the area outside the gas chamber through the opening defined by the first end portion of the movable member.

8. A method, comprising:
-
placing an outer housing associated with a medical injector into contact with a body, the outer housing defining a status window and enclosing an inner housing, a piston member, an indicator, and an energy storage member, the piston member configured to move an elastomeric member within the inner housing between a first elastomeric member position and a second elastomeric member position, the elastomeric member being in the first elastomeric member position before the placing such that at least one of a contents of the inner housing or a portion of the piston member is viewable through the status window; and moving an actuator relative to the outer housing such that the energy storage member produces a force to move the piston member, the elastomeric member moving from the first elastomeric member position to the second elastomeric member position in response to movement of the piston member, the indicator configured to move with the piston member from a first indicator position to a second indicator position after the actuator is moved, the indicator producing a visual indication when the elastomeric member is in the second elastomeric member position and the indicator is in the second indicator position. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A method, comprising:
-
viewing a contents of a container through a status window defined by a housing associated with a medical injector, the housing enclosing the container, a piston member, an indicator, and an energy storage member, the piston member being at least partially disposed within the container, the viewing occurring when the piston member and the container are in a first configuration and when the indicator is in a first indicator position; placing a contact member movably coupled to a distal end portion of the housing in contact with a target surface; and moving an actuator relative to the housing when the contact member is in contact with the target surface to release energy from the energy storage member such that the piston member and the container are moved from the first configuration to a second configuration, the indicator moving from the first indicator position to a second indicator position after the moving the actuator and when the contact member is in a fixed position relative to the housing, the indicator producing a visual indication when the piston member and the container are in the second configuration and the indicator is in the second indicator position. - View Dependent Claims (18, 19, 20, 21)
