近赤外分光法を使用した手術器具の清浄度評価システムの開発および判別評価方法の検証

抄録

A cleanliness evaluation system was developed that detects contamination remaining on surgical instruments by using near-infrared spectroscopy. Measurement attachments were developed that can easily measure the absorption spectrum of surgical instruments. A method for creating a discrimination database capable of highly accurate cleanliness evaluation was verified. Since the change in baseline of the absorption spectrum varies greatly depending on the shape and size of the surgical instrument, the discrimination database for cleanliness evaluation should not be created for absorption spectra that have been measured for various surgical instruments. However, after a database for the absorption spectra of one type of instrument with a nearly uniform baseline was created, it was possible to evaluate cleanliness with regard to the absorption peak of the remaining blood stains. Therefore, it is possible to develop a cleanliness evaluation system of surgical instruments by constructing respective discrimination databases for surgical instruments of different shapes and sizes.
