Title
(EN) PHOTOPLETHYSMOGRAM DEVICE WITH SKIN TEMPERATURE REGULATOR
(ZH) 具有皮肤温度调节器的光电容积描记设备
Abstract
(EN) A photoplethysmogram device is provided, comprising a light source configured to emit light to illuminate skin, a photo-detector configured to receive the light illuminating the skin and generate an electrical output as a function of an intensity of the received light, a skin temperature regulator configured to heat and/or cool a temperature of the skin adjacent to the photo-detector and light source to increase the signal-to-noise ratio (SNR) of the electrical output from the photo-detector, and a processor configured to generate, based on the electrical output, an output signal indicative of blood properties, including physiological parameters such as blood pressure, heart rate, stroke volume, cardiac output, total peripheral resistance, blood vessel elasticity, and arterial oxygen saturation.
(ZH) 提供了一种光电容积描记设备,包括:光源,被配置为发射光以照射皮肤;光电检测器,被配置为接收照射皮肤的光并且生成作为所接收的光的强度的函数的电输出;皮肤温度调节器,被配置为加热和/或冷却与光电检测器和光源相邻的皮肤的温度,以增加来自光电检测器的电输出的信噪比(SNR);以及处理器,被配置为基于电输出来生成指示血液性质的输出信号,包括诸如血压、心率、每搏输出量、心输出量、总外周阻力、血管弹性和动脉血氧饱和度的生理参数。
