Abstract
Systems, devices, and methods are described for using an autoinjector device. In one aspect, an autoinjector device comprises a housing and a plunger slidably mounted to the housing, the plunger including a tapered region. An actuator urges the plunger with respect to the housing from a storage position to a launch position, and a friction element about a portion of the tapered region resists a movement of the plunger from the storage position to the launch position.
Claims29
An autoinjector device, comprising:
- a housing;
- a plunger slidably mounted to the housing, the plunger including a tapered region;
- an actuator for urging the plunger with respect to the housing from a storage position to a launch position;
- and
- a friction element about a portion of the tapered region for resisting a movement of the plunger from the storage position to the launch position.
A method for actuating an autoinjector, the method comprising:
- applying a first amount of resistance against a movement of a plunger slidably mounted to a housing from a storage position to a launch position;
- and
- applying a second amount of resistance against a return of the plunger from the launch position to the storage position, wherein the second amount of resistance is smaller than the first amount of resistance.
