Description
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。
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。
