Title
(EN) STORAGE-STABLE, FLUID DISPENSING DEVICE USING A HYDROGEN GAS GENERATOR
(FR) DISPOSITIF DE DISTRIBUTION DE FLUIDE STABLE A LA CONSERVATION UTILISANT UN GENERATEUR D'HYDROGENE GAZEUX
Abstract
(EN)
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.
(FR)
Ce dispositif de distribution de fluide comprend un générateur (26) de gaz dans lequel l'humidité (eau) est comprise dans la réaction de génération de gaz. Une enveloppe (1) extérieure de chambre à gaz est utilisée afin d'empêcher ou de retarder la perte d'eau. Une membrane souple peut constituer une partie permanente du dispositif et peut être utilisée de façon conjointe avec le générateur de gaz. Le fluide distribué par ce dispositif est un liquide présentant une utilité particulière dans son milieu. Ce liquide peut être un liquide pharmaceutique, par exemple, exerçant un effet bénéfique ou curatif sur l'homme ou l'animal ou peut être un liquide tel qu'un insecticide, un fumigateur, un parfum ou un autre liquide, dont la pression de vapeur est relativement élevée.
