| 摘要 |
<p>The invention concerns a method for open-loop regulation of a breathing aid apparatus, which consists in: constituting a compression chamber (1), by dividing it into two compartments (3, 4) each connected to an intake (5, 7) of air or breathing mixture and to an outlet (6, 8) of compressed air, using an elastic floating diaphragm (2); guiding said floating diaphragm (2) by fixing its periphery to the wall of said chamber (1); fixing a field coil (14) at the centre of said floating diaphragm (2); placing said field coil (14) in an air gap (E) which is oriented in the direction deforming said floating diaphragm (2); measuring the instantaneous flow rate of air leaving through said outlet (6, 8) and powering said field coil (14) continuously calculating the instantaneous intensity and the direction of the supply current on the basis of the set pressure of compressed air, of said instantaneous flow rate and of the constants of said apparatus.</p> |
