The present application provides a self-powered drug-delivery device. The device includes a chamber having a wall. The chamber contains a fluid and is in connection with an administration means. The device also includes a displacement-generating battery cell. The device further includes an electrically-controlled battery unit, which includes the displacement-generating battery cell coupled to the chamber by a coupling means. The displacement-generating battery cell includes an element that changes shape as a result of charge or discharge of the battery cell so as to cause a displacement within the battery unit. The arrangement of the battery unit, the coupling means, the wall, the chamber, and the administration means is such that the displacement derived from the battery unit is conveyed by the coupling means to cause displacement of the wall of the chamber such that the fluid is expelled from the chamber to force a drug towards the administration means.

Drug delivery device

Embodiments include a displacement-generating battery cell for driving a drug-delivery device. The cell includes at least one volume-changing element. The cell also includes a housing formed according to a concertina-shaped design with folds in the walls thereof and containing an internal chemical reaction system. The arrangement of the chemical reaction system is such that as the cell is discharged, the volume-changing element expands, thereby lengthening the battery and thus reducing the extent of said folds, such that the cell becomes taller to reflect the expansion of the volume-changing component.

The present application provides a drug-delivery device comprising a drug reservoir chamber, containing a substance to be delivered, in fluid connection with a drug administration means, and an electrically-controlled battery unitcomprising at least one displacement-generating battery cellcoupled to the drug reservoir chamberby a coupling meansthe arrangement being such that the displacement derived from the battery unitis conveyed by the coupling meansto the drug reservoir chambersuch that the substance is expelled from the drug reservoir chambertowards the drug administration means
