Title (EN) MANUALLY-ACTUATED REDUCED PRESSURE PUMP HAVING REGULATED PRESSURE CAPABILITIES
(FR) SYSTÈME DE TRAITEMENT SOUS PRESSION RÉDUITE, ACTIONNÉ À LA MAIN, DOTÉ DE CAPACITÉS DE RÉGULATION DE LA PRESSION
Abstract: front page image
(EN)A manually-actuated reduced pressure pump comprising: a first barrel having a substantially cylindrical wall and a closed end; a piston movably disposed within the first barrel', a charging chamber being defined between the closed end of the first barrel and the piston; a piston spring operably associated with the piston to bias the piston in a direction that allows an increase in a volume of the charging chamber; a seal disposed within the first barrel, a regulated chamber being defined between the seal and the piston; a regulator passage providing fluid communication between the charging chamber and the regulated chamber; a second barrel operably associated with the piston to move the piston toward a compressed position when the reduced pressure pump is being manually actuated by a user; and a valve body operably associated with the regulator passage to selectively allow or prevent fluid communication between the charging chamber and the regulated chamber.
(FR)L'invention concerne un appareil de traitement sous pression réduite, qui comprend une chambre de charge stockant une première pression inférieure à la pression ambiante et une chambre régulée stockant une seconde pression inférieure à la pression ambiante. La première pression est inférieure à la seconde pression. Un conduit permet une communication fluidique entre la chambre régulée et la chambre de charge. Un élément régulateur est associé de façon opérationnelle au conduit pour empêcher la communication fluidique à travers le conduit lorsque la seconde pression est inférieure ou égale à une pression thérapeutique souhaitée et pour permettre la communication fluidique à travers le conduit lorsque la seconde pression dépasse la pression thérapeutique souhaitée.
