发明名称 Devices, systems and methods for medicament delivery
摘要 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.

主权项 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.
