Abstract: The specification describes an artificial resuscitation bag (5) having (i) a deformable bag (54) with a gas inlet (54A) and a gas outlet (54B), (ii) a pneumatic control valve (50) comprising an exhaust port (50c) adapted for controlling the flow of gas exiting to the atmosphere through said exhaust port (50c), and (iii) a monitoring module (60), operably connected to the pneumatic control valve (50) and having an absolute pressure sensor (60d) for measuring at least an absolute pressure (Pabs) in the inner compartment (50f) of the pneumatic control valve (50) and for transmitting at least an absolute pressure signal to a central processing unit (60c) and an ambient pressure sensor (60b) for measuring at least an atmospheric pressure (Patm) and for transmitting at least an atmospheric pressure signal to the central processing unit (60c).

Abstract: The present invention concerns a pneumatic delivery device having three successively-arranged chambers, a membrane element arranged in the third chamber so as to ensure a tight separation of the third chamber into a lower chamber and upper chamber, a membrane element arranged between the second chamber and the lower chamber of the third chamber so as to ensure a tight separation between said lower chamber and second chamber, a stem integrally fixed to the first membrane element and to the second membrane element, a valve cooperating with an outlet orifice arranged between the first chamber and the second chamber, and a flow adjustment element arranged on a gas conduct in fluid communication with the gas outlet of the second chamber, said flow adjustment element being operable by a user for setting a quantity of gas circulating in said gas conduct.

Abstract: The application describes a nasal sub-system (21) having: a hollow body (22) with an inner chamber (22a) and an inlet (22b) for receiving a respiratory gas, and a pair of nasal prongs (23, 24), in fluid communication with the inner chamber 22a of the hollow body 22, each nasal prong (23, 24) comprising a pair of inner channels (23b, 23c; 24b, 24c), each inner channels (23b, 23c; 24b, 24c) comprising a first channel (23b; 24b) and a second channel (23c; 24c) arranged in parallel, each first passage (23b; 24b) fluidly connecting the internal chamber (22a) of the hollow body (22) with a nostril (13, 14) of the patient (1), and each second passage (23c, 24c) fluidly connecting a nostril (13, 14) with a vent conduit (25) arranged in the hollow body (22) and in fluid communication with the atmosphere via at least one venting port (25a).
