Abstract
Processes and devices for delivering a fluid by decomposition of hydrogen peroxide are disclosed. Advantageously, the reaction is very fast and exothermic resulting in a fast ejection and, optionally, heating a fluid as it is ejected from a container. Also disclosed is a fluid flow system powered by a gas-generating reaction that is activated by an electrothermal activation switch.
Claims11
A fluid flow system, comprising:
- an activation switch;
- an electrical power source connected to the activation switch;
- a resistive heater attached to a first chamber;
- an electrical connection from the power source to the resistive heater;
- wherein the first chamber comprises a first reaction composition;
- a second chamber comprising a second reaction composition;
- wherein, if the first and second reaction compositions are combined, a gas is generated;
- wherein the resistive heater is adapted to open a pathway in the first chamber that creates an open flow path between the first and second chambers;
- the first chamber comprising at least one collapsible wall;
- a fluid chamber comprising a fluid;
- and
- a plunger adjacent the fluid chamber that is adapted to reduce volume of the fluid chamber when the gas is generated.
