METHOD FOR CORRECTING MEDICAL FLUID INJECTION PRESSURES BASED ON USAGE |
摘要 |
Certain embodiments of the invention are directed to a medical fluid injector of the type that uses a motor to drive fluid from a fluid container by receiving electrical energy from a power source. The medical fluid injector has a motor drive control that delivers electrical energy to the motor. The motor drive control measures electrical energy delivered to the motor and computes a pressure value of the fluid delivered based upon the measured electrical energy. This pressure value is computed utilizing a calibrated relationship between the electrical energy delivered to the motor and resulting fluid pressure from the fluid delivered. The control further tracks a time factor over an operative life of the motor and alters the calibrated relationship based upon the time factor. |
