Definitions

  • the present invention relates to a method for con ⁇ trolling, in respiration-synchronised manner, a portable air supply unit for a respirator covering at least the no and/or mouth of the user and having an air inlet and an a outlet, said air supply unit comprising an air inlet, an air filter, an air outlet communicating with the air inle of the respirator, a fan driven by an electric motor and supplying the respirator with air that has passed through the filter, a battery for driving the air supply unit, an an electrically operable valve for controlling the air fl to the respirator.
  • the object of the present invention is, therefore, to provide an air supply unit which in respiration-synchro ⁇ nised manner throttles the air flow to the respirator during exhalation, thus sparing the filter and reducing th exhalation resistance, and also controls the fan in a manner that minimises energy consumption.

Abstract

On décrit un procédé servant à régler, de manière synchronisée par rapport à la respiration, une unité portable d'approvisionnement en air pour un masque respiratoire (1) qui recouvre au moins le nez et/ou la bouche de l'utilisateur et qui comporte un orifice (3) d'arrivée d'air et un orifice (2) de sortie d'air. L'unité d'alimentation en air comprend un orifice d'arrivée d'air, un filtre à air, un orifice de sortie communiquant avec l'orifice d'arrivée d'air (3) du masque (1), un ventilateur actionné par un moteur électrique et fournissant de l'air filtré par le filtre (5) au masque respiratoire (1), une batterie alimentant l'unité d'alimentation d'air, et une valve (7) à commande électrique servant à régler l'écoulement d'air vers le masque (1). Le procédé consiste à détecter la pression dans le masque (1); à fermer la valve au début de chaque phase d'exhalation lorsque la pression atteint une valeur limite supérieure déterminée (Phi) et à ouvrir la valve à la fin de chaque phase d'exhalation lorsque la pression atteint une valeur limite inférieure déterminée (Plo); et à établir la tension de fonctionnement du moteur électrique de telle façon qu'une vitesse suffisamment élevée est transmise au ventilateur (6) afin que l'utilisateur ait accès à un surplus d'air filtré lors de la phase d'inhalation.
