Device (20) for determining the time of consumption of a gas by a patient comprising: - an internal gas passage (25) with a gas inlet (21) and a gas outlet (22), - connection means ( 8) that allow the device to be fluidly connected to a gas distribution outlet (30), - regulation means (23) that allow to regulate a desired gas consumption time (Tixjado), - display means (24) that allow visualization at least the desired gas consumption time (Tixjado), - means for determining the gas consumption time (5, 6) designed to measure the total gas consumption time (Consumption) during which gas circulates through said step internal gas (25), from the gas inlet (21) to the gas outlet (22), - information processing means (9) suitable and designed to compare the total gas consumption time (Consumption) determined by the means for determining the gas consumption time (5, 6) with the gas consumption time from eado (Tfijado), and - flow interruption means designed to interrupt any gas circulation by the said gas passage when the information processing means determine that the total gas consumption time (Consumption) is greater than or equal to the time of desired gas consumption (Tfijado). |
