Abstract
An injector includes a housing having a syringe assembly and an actuating mechanism at least partially disposed within the housing. The syringe assembly includes a syringe barrel that stores a medicament to be injected into a user, a needle assembly, and a filter member disposed adjacent to the needle assembly. The actuating mechanism is operatively coupled to the syringe assembly and includes a torque spring that exerts a torque to urge the medicament through the filter member to be injected into the user. The actuating mechanism further includes a damper mechanism that exerts an opposing force to dampen the motion exerted by the torque spring.
