Abstract: Injector systems which include a syringe and a powered injector to inject a fluid into a patient are described. The powered injector includes a drive member, an energy source, at least one sensor for detecting energy from the energy source, and at least one contact member axially movable in the injector and in communication with the sensor. The syringe includes at least one indicator positioned at a predetermined position, such as on a rear surface of an attachment flange, which may transmit or reflect energy from the energy source to the sensor. The contact member may contact and be moved by the indicator when the syringe is attached to the powered injector, so that the energy detected by the sensor may be determined by the position of the indicator. The position of the indicator thereby provides information about the syringe configuration.

Abstract translation: 描述了包括注射器和用于将流体注入患者的动力注射器的注射器系统。 动力喷射器包括驱动构件，能量源，用于检测来自能量源的能量的至少一个传感器，以及可在喷射器中轴向移动并与传感器连通的至少一个接触构件。 注射器包括位于预定位置（例如在附接凸缘的后表面上）的至少一个指示器，其可以将能量从能量源传递或反射到传感器。 当注射器附接到动力注射器时，接触构件可以由指示器接触并移动，使得由传感器检测到的能量可以由指示器的位置确定。 因此，指示器的位置提供关于注射器配置的信息。
