Patent ID: 7725168

Claim:
A contrast media injector system comprising: a powerhead including a syringe ram and a drive mechanism coupled with the syringe ram; a faceplate removably mounted to the powerhead, wherein the faceplate has an open condition and a closed condition; and circuitry configured to control the drive mechanism to move the syringe ram relative to the faceplate to effect an injection of a contrast media into a patient, the circuitry including programming for moving the syringe ram to a first position that prevents removal of the faceplate from the powerhead, wherein the programming of the circuitry is further configured to permit selective movement of the syringe ram to a second position that permits removal of the faceplate from and attachment of the faceplate to the powerhead, wherein the programming is further configured to prevent movement of the syringe ram from the first position to the second position while the faceplate is in the closed condition, and wherein the programming is further configured to allow movement of the syringe ram from the first position to the second position while the faceplate is in the open condition.
