DRUG DETECTION DEVICE AND DRUG DETECTION METHOD

摘要

[Problem] To provide a drug detection device and a drug detection method that enable the remaining amount of a drug to be calculated promptly and without contact. [Solution] The present invention is a drug detection device that detects a drug remaining in a target region and is provided with the following: an emission means that emits light rays containing near infrared radiation to the target region; a spectroscope upon which light reflected from the target region is incident; a near infrared radiation image pick up means that picks up images of spectrums dispersed by the spectroscope and that generates image pick up data; a control means that processes the image pick up data; and a storage means that stores arithmetic expressions that express the relationship between a predetermined amount of a drug and spectrum data based on the spectrums. The near infrared radiation image pick up means picks up an image of each spectrum in a predetermined number of pixels allocated within the target region. The control means by averaging pixel spectrums calculates the average spectral data in such region and on the basis of the arithmetic expression stored in the storage means calculates a drug amount that corresponds to the average spectrum data.
