Abstract: Disclosed is an NO delivery device for supplying an NO-containing gas, including an NO injection line, a flow rate measurement device and a valve device. The valve device is normally closed. An emergency line connected to the injection line includes an emergency solenoid valve, which is normally open, and a flow rate control device. An operating unit operates these elements. In the event of malfunction of the operating unit, the emergency solenoid valve passes to an open position, whilst the valve device passes to a closed position. The flow rate control device supplies the gas at a pre-fixed emergency flow rate of gas, determined on the basis of the gas flow rate measurements supplied by the flow rate measurement device during the normal functioning of the device prior to the malfunction. Gas supply installation including such an NO delivery device and a medical ventilator.

Abstract: The invention relates to an apparatus (1) for supplying an NO-containing gas, comprising an internal circuit (6) for conveying a flow of NO-containing gas, comprising valve means (7), control means (8) with a microprocessor (9), a tactile graphical display screen (4), and a gas analysis line (111) comprising at least one sensor (112). The control means (8) are configured to control, at a given time frequency, a temporary display, on the graphical display screen (4), of a first virtual selection key (81), the actuation of which by a user initiates a procedure of calibration of the sensor or sensors (112) of the gas analysis line (111).

Abstract: Disclosed is a mobile cart including a base for accommodating one or more gas cylinders, castors, a main column extending upwards from the base, a stowage cabinet arranged along the main column, an anchoring structure arranged at an upper end of the main column, a support post carried by the anchoring structure and equipped with fixing unit for a gas delivery apparatus, and a manual gripping handle allowing a user to manipulate the cart. Use of such a mobile cart to transport one or more cylinders of gas, in particular a NO/N2 mixture and/or oxygen, and a gas delivery apparatus.

Abstract: An additive gas delivery apparatus for delivery of additive gas to inspirational gas can be set to deliver the additive gas according to a dosing setting in normal therapy, and can be set to deliver according to a backup dosing setting in response disruption of signals representing data for controlling the delivery of additive gas according to the dosing setting in normal therapy. An additive gas delivery apparatus has an inlet for the additive gas and an integrated inlet for gas for oxygenating the patient that are connected to a backup line to mix the additive gas and gas for oxygenating the patient to a set concentration of additive gas in the gas mixture at an integrated backup outlet of the additive gas delivery apparatus.
