Abstract
Embodiments relate to systems comprising Active Wearable Medical Device (AWMD) with an osmotic chamber containing or configured to receive an osmotic agent, a permeability module for fluid ingress, and a drug chamber holding a drug. A compressible piston, positioned between the chambers, moves longitudinally as a whole during operation. The compressible piston advances toward the drug chamber when a valve opens, enabling drug release through one or more outlets, and retracts when the valve closes, driven by osmotic pressure. A valve module regulates this flow. The system also comprises a fluid chamber containing fluid and a semipermeable membrane coupling it to the AWMD. A channel connected to the drug outlets delivers the drug externally.
