The present invention includes an osmotic pump that includes a means for venting an osmotic composition included in the pump before the internal pressure of the pump has the opportunity to build to such an extent that the pump is structurally compromised, such as when one or more components of the pump are physically separated. The means for venting osmotic material included in an osmotic pump according to the present invention includes a vent that allows the material included in the osmotic composition of the pump to dissipate into an environment of operation at a rate that results in dissipation of the pressure created within the osmotic pump and a reduced potential for subject discomfort or irritation.
L'invention concerne une pompe osmotique comprenant un moyen d'évacuation d'une composition osmotique incluse dans la pompe avant que la pression interne de la pompe puisse s'accumuler et menacer l'intégrité structurelle de ladite pompe, par exemple lorsqu'un ou plusieurs composants de la pompe se séparent physiquement. Le moyen d'évacuation de la substance osmotique incluse dans une pompe osmotique de l'invention, comprend un évent permettant la dissipation de la substance incluse dans la composition osmotique de la pompe dans l'environnement de fonctionnement à une vitesse induisant la dissipation de la pression créée à l'intérieur de la pompe osmotique, et réduisant le risque d'irritation ou de gêne chez le sujet.
