First Claim
Patent Images
1. 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.

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.

25. 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. - View Dependent Claims (26, 27, 28)
