Abstract (en)
[origin: WO03037437A1] The invention relates to a respiratory apparatus comprising a housing (1), in which a valve seat (4), with an axially arranged air admission channel (6), a closing member (7), associated with said air admission channel on the exit side and a drive motor (8) are placed. A pressure sensor (15), for recording the pressure prevailing in the respective respiratory phase, is located in a measuring chamber (2), which links said air admission channel and the air exit channel (3), which is shaped in the housing and can be connected with a respiratory protective mask. Said drive motor, which is connected with the closing member of the valve device by means of a control system, is controlled on the basis of pressure ratios, prevailing on inspiration and expiration. The air supply to said respiratory protective mask is regulated according to a preset control feature. Apart from the air duct, which is exactly adapted to respiration, said respiratory apparatus is small and compact, requires few mechanical components and is insensitive to impact load.
