本申请涉及人体测量技术领域，尤其涉及一种人体压疮易发部位的自动预警方法及系统。
背景技术
压疮又称压力性损伤、压力性溃疡、褥疮，是由于局部组织长期受压，发生持续缺血、缺氧、营养不良而致组织溃烂坏死，压疮一般是自我不易或不能移动的病人的并发症。
压疮的形成是一个过程，在压疮形成前，辨别出病人身体上的压疮易发部位，并对压疮易发部位进行减压、按摩等护理，降低病人压疮的发生。而目前判断压疮易发部位是定期观察病人受压部位皮肤是否有颜色改变，如皮肤变紫色或褐红色，同时或伴疼痛、硬结、发热、冰冷来判断。
但是，由于每个人的体型、体重不同，不同人的不同体位其压疮易发部位也不同，因此判断病人身体上的局部皮肤是否为压疮易发部位，需要护理人员有丰富的压疮管理经验。
发明内容
本申请的主要目的在于提供一种人体压疮易发部位的自动预警方法及系统，旨在解决现有技术中判断病人身体上的局部皮肤是否为压疮易发部位，需要护理人员有丰富的压疮管理经验的技术问题。

进一步地，所述方法还包括：在所述标记的状态为预警状态，且所述预警状态持续预定时间后，发出声音警告。
进一步地，所述临界值为32mmHg；所述预定时间为6分钟。
进一步地，所述方法还包括：在所述标记的状态为非预警状态下，使用不同的标记表示所述压力传感器矩阵中不同的微型超薄动态压力传感器感应到的不同压力。

进一步地，所述方法还包括：接收来自患者穿戴的使用微型超薄动态压力传感器组成的穿戴设备的数据信号；根据所述穿戴设备上的微型超薄动态压力传感器的空间分布构建相应的标记图。
本申请第二方面提供一种人体压疮易发部位的自动预警系统，包括：传感器矩阵模块，用于感应与患者接触处的压力，并产生压力信号；矩阵图构建模块，用于使用状态可变的标记构建矩阵图；压力信号接收模块，用于接收所述传感器矩阵模块产生的压力信号；对应模块，用于将所述传感器矩阵模块中包含的每一个微型超薄动态压力传感器分别与所述矩阵图构建模块构建的矩阵图中的每一个标记相对应；预警模块，用于在所述压力信号接收模块接收到所述传感器矩阵模块感应到与患者接触部位的压力大于或等于临界值的压力信号后，将与所述压力传感器矩阵中感应到压力大于或等于临界值的微型超薄动态压力传感器相对应的所述矩阵图构建模块中矩阵图的标记状态改变为预警状态。

在本实施例中，压力传感器矩阵的面积为190cm×90cm，适合于一般身 材的患者平躺体位检测，压力传感器矩阵每2cm×2cm(4cm 2)内，镶嵌一枚微型超薄动态压力传感器，共4275枚传感器。4275个微型超薄动态压力传感器感受的压力信息经过一个集成压力信号处理系统处理，患者不同部位压力信息在计算机屏幕上以压力分布图形式显示，压力分布图与矩阵图相重合。
人体压疮易发部位的自动预警方法还包括：在标记的状态为预警状态，且预警状态持续预定时间后，发出声音警告。
在本实施例中，临界值为32mmHg，预定时间为6分钟。
一般情况下，患者的躯体受压严重的部位每6分钟左右要进行减压护理和按摩护理，当护理人员没有发现标记改变为预警状态6分钟后，发出声音警告来提醒护理人员，以降低护理人员对时间的把控不准确的情况发生。
