METHOD OF VARYING THE FLOW RATE OF FLUID FROM A MEDICAL PUMP AND HYBRID SENSOR SYSTEM PERFORMING THE SAME |
摘要 |
A system and method of varying the flow rate of fluid from a medical pump through tubing includes determining an inner diameter of the tubing and fluid flow velocity of fluid in the tubing with a controller based on acoustic signals received by a capacitive micromachined ultrasonic transducer sensor system and then determining and adjusting a fluid flow rate of fluid in the tubing with the controller. In addition, the same sensor system also detects air bubbles in the fluid in the tubing. |
