摘要
设计一种以ARM LPC1114单片机为核心的人体血氧饱和度检测仪.利用红外线装置对人体手指进行透射,采集透射后红外线的变化情况,并进行整形,放大,最后转化成数字量,利用扩散理论推导出的脉搏血氧饱和度计算公式得到血液中的含氧量,让使用者了解身体状况.测试表明,该样机在准确性和稳定性方面是比较理想的.
A human oximeter is designed with ARM LPC1114 singlechip. Using an infrared device transmit the human finger and collect the infrared ray after transmission. Coining and amplifing it and converting into digital signal. Oxygen saturation is computed with diffusion theory so that the user can know their physical status. The test shows that the prototype is ideal in accuracy and stability.
