摘要：
The invention concerns a gas delivery device (1) comprising an inner gaspassage(100) in fluid communication with a deformable reservoir (27), and aprocessing unit(51), such as an electronic board with a microcontroller. It further comprisesa firstdifferential pressure sensor (281) cooperating with the processing unit (51)fordetermining a pressure (P) in the deformable reservoir (27), and aproportional valve(22) arranged on the inner gas passage (100) for controlling the flowrate ofgas in saidinner gas passage (100). The processing unit (51) controls the proportionalvalve (22)for adjusting the flowrate of gas passing through said proportional valve (22)on thebasis of said pressure (P) in the deformable reservoir (27). The gas can be amixture ofoxygen and nitrous oxide useable for relieving anxiety, for providing lightsedations orfor treating pain. The gas is delivered by means of a mask, such as an oro-nasal mask.
