Injection system and pumping system for use therein |
摘要 |
The present invention provides a number of pumping systems and injection systems particularly useful for injecting a liquid medium into a patient. In general, the pumping systems comprise a removable pumping unit. The removable pumping unit includes means for pressurizing the liquid medium via the rotational displacement of the liquid medium. The present invention also provides a pumping system comprising a pumping unit for pressurizing the liquid medium and a feedback-controlled drive means in connection with the pumping unit for providing a controlled powered drive to the pumping unit. The pumping system further comprises a flow meter for measuring the flow rate of the pressurized liquid medium exiting the pumping system and control means in communicative connection with the drive means for providing a control signal to control the powered drive provided to the pumping unit. The control means is suitable to receive a feedback signal from the flow meter corresponding to the flow rate of the pressurized liquid medium exiting the pumping unit. The control signal provided to the drive means is a function of the feedback signal.
