Abstract: An installation for supplying gas to a patient, comprises an NO delivery device, an NO injection line with a valve device, a backup line that connects to the injection line and comprises a backup solenoid valve and a flow rate control device, and control means; and a medical ventilator that supplies a respiratory gas to a patient circuit to which the NO delivery device is connected. A flow rate sensor supplies the control means with a measurement signal of the gas flow rate in the patient circuit. In the event of interruption of reception of the measurement signal, the backup solenoid valve switches to an open position, the valve device switches to a closed position and the flow rate control device supplies the NO/N2 mixture at a pre-regulated backup flow rate, determined on the basis of the measurement signal supplied by the flow rate sensor, before said interruption.

Abstract: The invention relates to a device (1) for supplying therapeutic gas, in particular NO/N2 mixtures, comprising an internal passage (2), valve means (5), control means (6) with microprocessor, and selection means (8), which can be actuated by a user and are configured to allow the user to start a supply of gas or stop a supply of gas. The selection means (8) supply the control means (6) with a command signal corresponding to the choice made by the user, in order to control, via the valve means (5), the flow of gas in the internal passage (2), i.e. to authorize or stop any flow of gas. The control means (6) count a total duration of actual supply of gas equal to the sum of all the time periods elapsing between a choice, made by the user, of starting a supply of gas and a choice, made by the user, of stopping a supply of gas. Installation for administering gas to a patient, which includes such a gas supply apparatus.

Abstract: The invention relates to an apparatus for supplying NO (1), such as an NO/N2 gaseous mixture, comprising a main gas circuit (40; 40.1, 40.2) with flow rate control means (42, 43) comprising at least one main solenoid valve (42) operated by the operating means (50) in order to control the flow rate of NO/N2 mixture passing through said at least one main solenoid valve (42). The main solenoid valve (42) is a proportional solenoid valve having degrees of opening of between 0 and 100%, and is configured to function in at least two given operating ranges corresponding to different degrees of opening of the main solenoid valve (42). The operating means (50) are configured to control the main solenoid valve (42) in pulsed mode in one of the operating ranges so as to deliver successive gas pulses (IG) and in proportional mode in another operating range.
