  • Device for Controlled Delivery of an Injectable Liquid
    Publication number: 20070065319
    Abstract: A device for the controlled delivery of an injectable liquid from a liquid container, wherein a flexible force transferor transfers the drive force of a drive wheel onto a piston which can be slid axially in the device, a permanently acting restoring force of a spiral spring is applied to the drive wheel to advance the piston and expel the liquid, and a lock locks the drive wheel against rotation and releases the drive wheel to expel the liquid. In one embodiment, the amount of liquid expelled can be indicated by audible clicks and, in one embodiment, the drive wheel moves only incrementally when the lock releases the drive wheel.
