Title
(EN) IMPROVED PLEURAL DRAINAGE DEVICE AND VALVE FOR SUCH
(FR) DISPOSITIF DE DRAINAGE PLEURAL PERFECTIONNÉ ET VALVE POUR UN TEL DISPOSITIF
Abstract
(EN)
A drainage device useable for treating patients with a pulmonary air leak, the device comprising suction mode control means, where a pressure sensor is connected to the suction mode control means for supplying a pressure signal representative of the pressure in a collection chamber, and an air flow sensor is connected to the suction mode control means to supply a flow signal representative of the flow of air evacuated from the collection chamber, and in that the suction mode control means is arranged to switch between a first suction mode and a second suction mode based on an algorithm involving the flow signal and the pressure signal.
(FR)
L'invention porte sur un dispositif de drainage qui peut être utilisé pour traiter des patients présentant une fuite d'air du poumon, le dispositif comprenant des moyens de commande de mode d'aspiration, où un capteur de pression est raccordé aux moyens de commande d'aspiration pour transmettre un signal de pression représentatif de la pression dans une chambre de collecte, et un capteur d'écoulement d'air est raccordé aux moyens de commande de mode d'aspiration pour transmettre un signal d'écoulement représentatif de l'écoulement de l'air évacué de la chambre de collecte, et les moyens de commande de mode d'aspiration étant agencés pour commuter entre un premier mode d'aspiration et un second mode d'aspiration sur la base d'un algorithme impliquant le signal d'écoulement et le signal de pression.
