VENTILATOR FLOW VALVE

Described herein is a flow control valve for a ventilator that controls gas flow through a patient line in response to a target pressure within the line. The valve controls gas flow by (i) providing both a high frequency signal and a low frequency signal through a coil positioned in a fixed magnetic...

description	Described herein is a flow control valve for a ventilator that controls gas flow through a patient line in response to a target pressure within the line. The valve controls gas flow by (i) providing both a high frequency signal and a low frequency signal through a coil positioned in a fixed magnetic field, (ii) determining a position of the coil by detecting the high frequency signal, and (iii) controlling a position of the coil by adjusting the low frequency signal based on the determined position and/or velocity of the coil. La présente invention concerne une soupape de régulation d'écoulement pour ventilateur qui régule l'écoulement gazeux dans une conduite d'un patient en réaction à une pression cible dans la conduite. La soupape régule l'écoulement gazeux par (i) la génération d'un signal haute-fréquence et d'un signal basse-fréquence à travers une bobine positionnée dans un champ magnétique fixe, (ii) par la détermination d'une position de la bobine au moyen de la détection du signal haute-fréquence, et (iii) par le réglage d'une position de la bobine par ajustement du signal basse-fréquence sur la base de la position déterminée et/ou de la vitesse de la bobine.
