Abstract

本发明公开了一种血压监测方法，本方法采用压力或震动传感器在体表感应人体动脉的搏动（压力或震动），产生相应的电信号。通过对该电信号的分析计算得出血压值。本方法与现有血压计采用方法的本质区别在于：本方法是在正常状态下采集人体体表动脉的搏动信号，并对该搏动信号分析计算得到血压值。采用本方法的血压监测仪器无需加压气泵，能够用于长期连续血压监测。

Description

一种血压监测方法
【技术领域】
本发明涉及血压监测技术领域， 具体涉及一种新型的血压监测仪器的 方法或原理， 采用该方法的血压监测仪器， 无需加压气泵， 能够用于长期 连续血压监测。
【背景技术】
现有技术中的无创血压测量方法有听诊法和示波法。 听诊法是通过听 说
柯式声来判别收缩压、 舒张压， 其读数受医生的情绪、 听力、 环境噪声、 被测者的紧张等一系列因素的影响， 易引入主观误差。 目前的电子血压计 书
采用了示波法， 通过建立收缩压、 舒张压、 平均压与袖带压力震荡波的关 系来判别血压。 这两种方法在测量血压时，都需要首先对袖带充气，因此， 不易于进行长期连续血压监测。
【发明内容】
本发明的主要目的是提供一种有效的血压监测方法， 无需加压气泵， 能够实现长期连续血压监测。
为实现上述目的， 本发明的方法， 直接采用压力或震动传感器来感应 人体体表动脉的搏动， 得到相应的电信号。 通过对该电信号的分析计算得 到血压值。 在血压的整个量测过程中， 不需要加压气泵， 因此， 可以用于 长期连续的血压监测。
本发明的有益效果是：
1、 连续测量。采用本血压监测方法测量血压，不需要测量时先行打 气， 可不间断地测量。
2、 使用方便。采用本血压监测方法测量血压， 不需要打气， 且只需 要在腕部粘贴一个传感器即可， 也可以通过舒适弹性织物将传 感器固定在腕部。
【具体实施方式和附图说明】
本申请的特征及优点将通过采用本方法的一种血压计实施例， 结合附 图进行说明。
图 1是本发明方法推荐选用的一种血压传感器的示意图， 由外壳、 引 线、 上下电极和高分子压电材料组成， 高分子压电材料填充在上电极和下 电极之间。 该血压传感器可根据需要， 制成任意形状和面积不等的薄膜。
图 2是基于本发明方法的一种血压计的示意图， 包括血压传感器和主 机。 血压传感器可以直接粘贴在腕部， 也可以通过舒适弹性织物固定在腕 部。 血压传感器感应腕部动脉的搏动， 输出相应的电信号， 经过主机的分 析计算得出血压值。
以上内容是结合一种实施方式对本发明所作的进一步详细说明， 不能 认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普 通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干简单推 演或替换， 都应当视为属于本发明的保护范围。
