DEVICE FOR DETECTING INJECTION BUTTON INPUT OF INJECTOR

摘要

PURPOSE: A syringe and an injection button detecting device are provided to detect injection pressure of the injection button of the syringe. CONSTITUTION: An injection button detecting device comprises a syringe(100), and an injection amount measuring unit(200). The syringe is formed with a resonance circuit through a coil or a capacitor which are installed inside the injection button. The injection amount measuring unit senses the input of the injection button of the syringe when voltage is generated from the coil.
