Abstract

See full text

An injector for use in injecting a fluid in a medical injection procedure includes a drive having a motor to pressurize the fluid; a sensor to provide a measure of fluid pressure; and a pressure monitor in communication with the sensor and the drive to stop the motor using 4-quadrant control when the sensor communicates a measured pressure of at least a pressure hazard limit. The pressure monitor also limits power input to the motor to a power limit once the sensor communicates a measured pressure of at least a power limiting pressure. The power limiting pressure is below the pressure hazard limit.
