Abstract

Titre de l’invention Ventilateur médical à deux entrées d’oxygène et capteur de pression d’oxygène commun L’invention concerne un ventilateur médical (50) comprenant un circuit (1) d’alimentation en O2 avec des tronçons de circuit (12, 13) comprenant une entrée d’oxygène HP (2) pour recevoir du gaz à haute pression (HP) et une entrée d’oxygène BP (3) pour recevoir du gaz à basse pression (BP) se raccordant fluidiquement l’un à l’autre (14) pour former une ligne commune (15) d’amenée d’oxygène. Un capteur de pression (16) opère des mesures de pression du gaz au sein de l’un de ces tronçons de circuit (12, 13) ou de la ligne commune (15). Une partie de la ligne commune (15) et des tronçons de circuit (12, 13) est aménagée dans un bloc (10) agencé dans le ventilateur médical (50). Le bloc (10) comprend en outre une chambre interne (11) en communication fluidique avec la ligne commune (15), ou l’un des tronçons de circuit (12, 13), et dans laquelle est agencé le capteur de pression (16) de manière à mesurer la pression du gaz dans la partie de la ligne commune (15) ou des tronçons de circuit (12, 13) traversant le bloc (10). Figure de l’abrégé : Fig. 4Title of the invention Medical ventilator with two oxygen inlets and common oxygen pressure sensor The invention relates to a medical ventilator (50) comprising an O2 supply circuit (1) with circuit sections (12, 13) comprising an HP oxygen inlet (2) for receiving high pressure (HP) gas and a LP oxygen inlet (3) for receiving low pressure (LP) gas fluidly connecting to each other another (14) to form a common oxygen supply line (15). A pressure sensor (16) performs gas pressure measurements within one of these circuit sections (12, 13) or the common line (15). Part of the common line (15) and circuit sections (12, 13) is arranged in a block (10) arranged in the medical ventilator (50). The block (10) further comprises an internal chamber (11) in fluid communication with the common line (15), or one of the circuit sections (12, 13), and in which the pressure sensor (16 ) so as to measure the gas pressure in the part of the common line (15) or of the circuit sections (12, 13) passing through the block (10).
