The invention belongs to the technical field of detection equipment, and particularly relates to a photoelectric detection device and method for monitoring the concentration of medicine in a blended infusion bag. The device comprises a shell, an infusion bag placing frame, a main control MCU, a measurement module, an amplification filter circuit and an image recognition module. The detection method of the device comprises the following steps: establishing a medicine concentration working curve database in the main control MCU memory; selecting the type of a to-be-detected medicine; measuring a reference voltage; placing a finished infusion bag; identifying medicine types; judging the placement position of the finished infusion bag to be detected; acquiring a measurement voltage after signal amplification; calculating the ratio of the measured voltage to the reference voltage; measuring the medicine concentration of the finished infusion bag; judging whether the concentration is consistent; testing the next fi
