This syringe pump is compatible with all standard syringes, and can automatically detect the syringe size. It is equipped with a bedside injection supervision system that assures accuracy in even the smallest injection doses. The double central processing unit system ensures safety and reliability. The pump is operated with a precision step motor, and there are no pulsating waves even during small injections. The pump includes an audible and visual alarm, pressure sensor that easily detects occlusion pressure, and an internal error diagnostic system that will automatically stop the system's operation if an error occurs to maintain safety.
