Abstract
A drug delivery device having a housing containing a gas generator controlled by an electronic controller. The gas generator generates gas into a reciprocable chamber, whereby reciprocation of the chamber causes a lever to reciprocate a pawl, and this action causes a ratchet to undergo incremental advancement. The device may also be provided with manual control for delivering a bolus dose of drug when necessary.
Claims21
A drug delivery device comprising:
- a housing containing a drug reservoir;
- means for facilitating expulsion of drug from the drug reservoir;
- a mechanism in communication with the facilitation means, operable to undergo incremental advancement and thereby drive the drug from the reservoir;
- a member operatively associated with the mechanism to cause the incremental advancement of the mechanism as the member moves in a first direction;
- and gas generating means located within the housing and operable to expand in a chamber, the member being in transmission relation to the chamber, whereby the member is driven by the movement of the chamber to advance the mechanism and thereby drive the drug from the reservoir in incremental fashion.
