Abstract

Saturation of peripheral oxygen (SpO2) is one of the most important parameters of vital signs. Pulse oximeter which based on near-infrared spectroscopy is commonly used as a non-invasive method to measure SpO2. Currently, medical device manufacturers as well as metrology measurement agencies in China usually use pulse oximeter simulator as the commonly accepted functional calibration equipment for pulse oximeters. So far, there is no experimental protocol or devices can be used to test the accuracy and reliability of a pulse oximeter simulator, therefore, a set of new metrology apparatus with the name of pulse oximeter simulator calibration equipment have been designed in order to make a traceable system for the calibration or verification of pulse oximeter simulators. The principles and some research methods of this pulse oximeter simulator calibration equipment will be discussed in this paper. Besides that, many experiments have been applied in order to guarantee the accuracy as well as traceability of this set of equipment.
