Processes and devices for delivering a fluid by chemical reaction are disclosed. A chemical reaction is initiated in a reaction chamber to produce a gas, and the gas acts upon a piston to deliver the fluid. An exemplary device may include an upper chamber, a lower chamber, a fluid chamber, a piston between the lower chamber and the fluid chamber, and a one-way valve between the upper chamber and the lower chamber.

Process and device for delivery of fluid by chemical reaction

Processes and devices for delivering a fluid by chemical reaction are disclosed. A chemical reaction is initiated in a reaction chamber to produce a gas, and the gas acts upon a piston to deliver the fluid. Preferred devices typically include an upper chamber, a lower chamber, a fluid chamber, a piston between the lower chamber and the fluid chamber, and a barrier between the upper chamber and the lower chamber. When the barrier is broken, reagents in the upper chamber and the lower chamber are mixed together to generate the gas.

Chemical engines and processes for their use and construction are described. The chemical engines can provide powerful and compact devices, especially autoinjectors for the rapid, powered injection of viscous medicines. Novel formulations and designs of chemical engines and delivery technologies employing the chemical engines are described.
