1. A device for supplying therapeutic gas, comprising:
an internal passage through which flow of the therapeutic gas between a gas inlet and a gas outlet is to be conveyed,
at least one valve configured to control the flow of the therapeutic gas in the internal passage,
a controller configured to control the at least one valve,
a graphic display configured to display choices that can be selected by a user, and
a user interface configured to allow a selection by the user from among the choices displayed on the graphic display,
wherein the controller is configured to count a total number (N) of patients treated by administration of the therapeutic gas from the selection, by the user, via the user interface, of a first given choice corresponding to a start of a treatment by administering the therapeutic gas to a patient concerned,
wherein the controller is configured to determine a total duration of treatment for each patient treated which corresponds to a period of time elapsed between the user selecting:
the first given choice corresponding to the start of treatment by administering the therapeutic gas to the patient concerned, and
a second given choice corresponding to an end of treatment by administering the therapeutic gas to the patient concerned, and
wherein the controller is configured to determine, from the total number (N) of patients treated, which has been counted up, and from the total durations of treatment determined for the patients treated:
a number of short treatments (TC) for which the total duration of treatment is below a preset threshold duration, and
a number of long treatments (TL) for which the total duration of treatment is above the preset threshold duration.
