一种柔性连续脉搏血氧饱和度监测器
技术领域
本发明公开了一种柔性连续脉搏血氧饱和度监测器，它涉及医疗设备领域，可应用于需要长期进行血氧饱和度监测的多种场所。
背景技术
近年来，我国的心脑血管疾病仍呈逐年上升趋势，其发病率和死亡率均居各种疾病之首，社区医院，家庭医疗保健中心对于能够连续监测心血管状况的医疗设备的需求十分强烈。
脉搏血氧饱和度监测装置是用来测量人体脉搏以及血氧饱和度的装置，血氧饱和度反映了血液中氧气的含量，对于机体维持新陈代谢非常关键，有效监测动脉中氧含量的水平是判断血液循环系统、人体呼吸系统是否出现障碍的重要指标，因此对脉搏血氧饱和度的监测和分析处理具有很高的医学价值和应用前景，目前市面上检测血氧饱和度的仪器种类繁多，但是能实现佩戴舒适，长时间连续脉搏波血氧饱和度监测的装置不多，且人体的生物信号多属于低频弱信号，必需经过放大和后级滤波以满足采集的要求，容易受到干扰，普通的监测装置负荷较重，佩戴舒适度差，难以满足长时间连续脉搏波血氧饱和度监测的要求。
为了解决上述问题，设计一种柔性连续脉搏血氧饱和度监测器是非常必要的。
发明内容
针对现有技术上存在的不足，本发明目的是在于提供一种柔性连续脉搏血氧饱和度监测器，该监测器结构简单，设计合理，使用方便，功耗低，具有与远程终端交互的能力，可以进行长时间连续脉搏波血氧饱和度监测。
为了实现上述目的，本发明是通过如下的技术方案来实现：一种柔性连续脉搏血氧饱和度监测器，包括通过柔性电路连接的：
发光LED阵列(1,101,102,103)，所述发光LED阵列发出检测光；
至少一个光电接收管(2)，用于接收所述检测光并转化为电信号；
信号处理单元(3)，所述信号处理单元(3)对所述电信号进行处理并提取出连续脉搏血氧饱和度信号；以及
电源(4、5)，所述电源为所述监测器整体供电。
所述信号处理单元(3)进一步包括微处理器控制及存储模块(301)、无线收发模块(302)、信号调理模块(303)、显示模块(304)，所述微处理器控制及存储模块(301)分别与无线收发模块(302)、信号调理模块(303)、显示模块(304)连接；微处理器控制及存储模块(301)用于本地存储；所述信号调理模块(303)对所述电信号进行处理并提取出连续脉搏血氧饱和度信号；所述无线收发模块(302)与远程终端(7)无线连接，用于传送告警信息；所述显示模块(304)用于显示所述连续脉搏血氧饱和度。
作为优选，所述的可自动校准的发光LED阵列包括至少两个两种不同波长的LED发光模块，可根据检测到的信号质量自动调整发光的LED模块，实现自动优选对准的功能，解决LED发射管与接收管不能正对，产生偏离，影响测量精度的问题。
作为优选，信号调理模块中包含至少两个可自动校准的发光LED阵列的驱动电路，驱动电路是使用多选一模拟开关选通的复用电路，在电路上优化设计，简化结构，降低功耗。
作为优选，电源可以是普通锂电等各种电池，也可以是带能量获取装置的新型能源(如温差供能等)，柔性电池。从能源供给上，为长时间连续脉搏波血氧饱和度监测提供基础保障。
本发明的有益效果：该装置无需结构外壳，可根据需要由使用者采用柔性材料(胶布、指套)等固定或自粘于组织表面。超低功耗无线收发模块与远程终端无线连接，用于传送告警信息，告警门限可由远程终端设置，无线模块可接入家庭医疗保健中心完成报警，提示功能，进一步地与社区医院，中心医院对接。因此，该装置佩戴舒适，可以超过24小时长时间连续脉搏波血氧饱和度监测，具有较强的抗干扰能力，应用前景广阔。
