STORAGE-STABLE, FLUID DISPENSING DEVICE USING A HYDROGEN GAS GENERATOR

摘要

A fluid delivery device includes a gas generator (26) in which moisture (water) is involved in the gas generation reaction. An external gas chamber shell (1) is utilized to prevent or retard water loss. A flexible diaphragm (3) may be a permanent part of the device and may be utilized in conjunction with the gas generator. The fluid delivered by such device is typically a liquid having some particular utility in its environment. The liquid dispensed may be a pharmaceutical or some other liquid having a beneficial or curative effect upon an animal or human patient or it may be a liquid such as an insecticide, fumigant, fragrance or other liquid having a relatively high vapor pressure.
