Medical fluid injector

A a syringe (2) comprises: An air detection system (122), comprising a surveying the air in a neck; A manual control rod (29), for controlling injector transmission tube; andMagnetic conductance body (94), they for magnetic field of the panel of transmission power cover has an internal circuit board is, thus capable of measuring the different panel; An inclination angle sensor (158), comprising a surveying angle of the inclined of power head, a control speed of a speed of movement of the manual control rod formed, and a control reversible screen (30); And monitor the microcontroller (192,196,198), they for monitoring control injector's central processor (175,193,194), thus end is measurement and react to the error status.
