This article describes the design of a portable blood oxygen simulation system that can be used to simulate various
blood gas saturation states of the human body. The system can be used to simulate various states of blood gas
saturation, and can also simulate large blood oxygen saturation dynamic range, pulse rate range and perfusion
index range. It can be used for testing, but not for clinical examination instruments. Moreover, the system has the
characteristics of small size and low cost compared with the commercial blood oxygen simulator. Although the
simulation system is not directly used for the detection of blood gas saturation of patients, it is also an essential
equipment in the production and testing process, so it has certain practical value.
