| 摘要 |
The invention relates to a regulation and control system of oxygen flow for an oxygen-dependant patient, essentially comprising an oxygen source (2), a regulation solenoid valve (11), an upstream tube (21) connecting the oxygen source (2) to the regulation solenoid valve (11), a flow sensor (12), a pressure sensor (13) and a microcontroller (14). Said system is characterised in that the microcontroller (14) controls the opening of the regulation solenoid valve (11) such as to regulate in form and size the flow of the amount of oxygen contained in the upstream tube (21) and managing the bolus effect. |
