Medical ventilator with PEEP-controlled valve

Abstract

Title of the Invention: Medical Ventilator with Pilot-Controlled PEEP Valve. The invention relates to a medical ventilator (100) comprising a motorized turbine (41) for supplying gas, controlled by control means (40). A gas circuit (102) with an inspiratory limb (102.1) and an expiratory limb (102.2) in fluidic communication with the atmosphere. A PEEP valve (1), arranged on the expiratory limb (102.2), comprises a flapper (2) cooperating with a flapper seat (3). An electromechanical control device (20), controlled by the control means (40), acts on the rear face (2.2) of the flapper (2) to push it towards the flapper seat (3). A pressurization chamber (22) in fluidic communication with a pressure supply line (42) is supplied by the turbine (41) and cooperates with the flapper (2). Figure from the summary: Figure 2
