Description

一种心脏功能监测方法  Heart function monitoring method
【技术领域】  [Technical Field]
本发明涉及心脏功能监测领域，具体涉及一种心脏功能监测的新方法， 该方法与传统心电监测方法的本质区别在于， 传统心电图记录的是在每个 心动周期中体表的生物电的变化， 而采用本方法记录的是在每个心动周期 中体表的压力或震动的变化。  The invention relates to the field of cardiac function monitoring, in particular to a new method for monitoring cardiac function, and the essential difference between the method and the traditional ECG monitoring method is that the traditional electrocardiogram records the bioelectrical changes of the body surface in each cardiac cycle. What is recorded by this method is the change in pressure or vibration of the body surface during each cardiac cycle.
【背景技术】 【Background technique】
基于心电过程认知体系的心电图， 发明于上个世纪初， 长期以来， 一 直是心脏疾病检测中应用最广泛的仪器，为人类健康事业做出了重大贡献。  The electrocardiogram based on the ECG process cognition system, which was invented at the beginning of the last century, has long been the most widely used instrument for heart disease detection and has made significant contributions to the cause of human health.
心电图指的是心脏在每个心动周期中， 由起搏点、 心房、 心室相继兴 奋， 伴随着的生物电的变化， 通过心电描记器从体表引出多种形式的电位 变化的图形。 心电图代表整个心脏电激动的综合过程， 以一个个心肌细胞 的电激动为基础， 心肌激动时细胞内发生电传变化。 心电图被认为是心脏 兴奋的发生、 传播及恢复过程的客观指标。  The electrocardiogram refers to the heart in each cardiac cycle, the pacemaker, the atria, the ventricle are successively excited, accompanied by the changes in bioelectricity, through the electrocardiograph to draw a variety of forms of potential changes from the body surface. The electrocardiogram represents a comprehensive process of electrical stimulation of the entire heart, based on the electrical activation of one cardiomyocyte, and a teletype change occurs in the cell during myocardial activation. An electrocardiogram is considered to be an objective indicator of the occurrence, spread, and recovery of cardiac excitability.
应用最广泛的是普通心电图及动态心电图。普通心电图应用范围如下： The most widely used are common electrocardiograms and dynamic electrocardiograms. The general ECG application range is as follows:
( 1 ) 对心律失常和传导障碍具有重要的诊断价值； （2 ) 对心肌梗塞的诊 断有很高的准确性， 它不仅能确定有无心肌梗塞， 而且还可确定梗塞的病 变期部位范围以及演变过程； （3 )对房室肌大、 心肌炎、 心肌病、 冠状动 脉供血不足和心包炎的诊断有较大的帮助； （4 )能够帮助了解某些药物（如 洋地黄、 奎尼丁） 和电解质紊乱对心肌的作用。 (1) has important diagnostic value for arrhythmia and conduction disorders; (2) has high accuracy in the diagnosis of myocardial infarction, it can not only determine the presence or absence of myocardial infarction, but also determine the extent of the lesion during the infarction. Evolution process; (3) great help for atrioventricular myocardium, myocarditis, cardiomyopathy, coronary insufficiency and pericarditis; (4) can help understand certain drugs (such as digitalis, quinidine) And the effects of electrolyte imbalance on the myocardium.
动态心电图是长时间连续记录动态心脏活动的方法。 它能充分反映受 检查者在活动、 睡眠状态下心脏出现的症状和变化， 适用于检查一过性心 律失常和心肌缺血，对心律失常能定性、定量诊断并能了解心脏储备能力。  A dynamic electrocardiogram is a method of continuously recording dynamic cardiac activity over a long period of time. It can fully reflect the symptoms and changes of the heart in the activity and sleep state of the examinee. It is suitable for the examination of transient arrhythmia and myocardial ischemia. It can qualitatively and quantitatively diagnose arrhythmia and understand the reserve capacity of the heart.
但是， 心电图监测需要在患者身上粘贴多个电极， 存在明显的缺点： However, ECG monitoring requires multiple electrodes to be attached to the patient, with significant drawbacks:
( 1 )电极粘贴的位置比较严格，需要专门人员操作； (2 )电极是一次性的， 每次使用都需要更换电极； （3 ) 电极内置电解液， 电解液具有腐蚀性， 如 果长期使用， 会使局部皮肤瘙痒、 甚至溃烂； （4 ) 影响患者的正常生活和 工作。 本发明提出了一种全新的心脏功能监测方法， 我们可以称之为心动监 测方法。 该方法采用压力或震动传感器感应心脏跳动在人体体表引起的振 动， 并将其转变为相应的电信号。 该信号直接反映了心脏的跳动功能， 能 够用于分析心脏功能的健康和异常。 (1) The position of the electrode is relatively strict and requires special personnel to operate; (2) The electrode is disposable, and the electrode needs to be replaced every time; (3) The electrolyte is built in the electrode, and the electrolyte is corrosive. If it is used for a long time, It will cause itching and even ulceration of the local skin; (4) affect the normal life and work of the patient. The invention proposes a new method for monitoring cardiac function, which we can call a cardiac monitoring method. The method uses a pressure or vibration sensor to sense the vibration caused by the heartbeat on the body surface and convert it into a corresponding electrical signal. This signal directly reflects the heart's beating function and can be used to analyze the health and abnormalities of heart function.
事实上， 在每个心动周期中体表的 "生物电的变化"和 "压力 （或震 动） 的变化"相比， 哪个更准确地反映心脏的功能， 可能还需要进一步的 研究。  In fact, further studies may be needed to more accurately reflect the function of the heart in the “bioelectric changes” and “pressure (or shock) changes” of the body surface during each cardiac cycle.
我们有理由相信， 直接监测心脏的跳动过程， 应该会更好， 因为它更 加直观地反映了心脏的功能。  We have reason to believe that direct monitoring of the heart's beating process should be better because it more intuitively reflects the function of the heart.
今天， 现代医学还不能完美解释心脏的跳动和心脏的生物电之间的因 果关系， 就像现代科学还不能回答先有鸡还是先有蛋的问题。  Today, modern medicine does not perfectly explain the causal relationship between the beating of the heart and the bioelectricity of the heart. Just as modern science cannot answer the question of whether there is a chicken or an egg first.
但是， 至少， 在每个心动周期中体表的压力 （或震动） 变化能够反映 心脏的功能。 同时， 由于获取体表的压力 （或震动） 的变化比获取体表的 生物电的变化， 在技术上可以有更多的选择， 比如采用压电薄膜、 压电陶 瓷、 MEMS等不同的传感材料或器件， 使得采用本发明方法的心脏功能监 测仪器具有更好的易用性， 可以克服心电图的不足。  However, at least, changes in the pressure (or vibration) of the body surface during each cardiac cycle can reflect the function of the heart. At the same time, because the change of the pressure (or vibration) of the body surface is better than the bioelectricity of the body surface, there are more technical choices, such as piezoelectric film, piezoelectric ceramics, MEMS, etc. The material or device enables the cardiac function monitoring instrument using the method of the present invention to have better ease of use and overcome the deficiency of the electrocardiogram.
以采用压电薄膜材料的传感器为例， 基于本发明方法的心脏功能监测 仪器的有益效果是：  Taking a sensor using a piezoelectric film material as an example, the beneficial effects of the cardiac function monitoring instrument based on the method of the present invention are:
( 1 )传感器粘贴的位置容易确定， 不需要专门人员操作； （2 )传感器 直接接触人体即可， 不需要额外的电极； （3 )传感器可以重复并长期使用， 对身体和皮肤没有副作用； （4) 不影响使用者的正常生活和工作； （5 ) 可 以长期连续监测， 这样有助于心脏疾病的更早期发现和心脏病患者心脏功 能危险预警； （6) 为心脏功能的研究提供一种新的手段， 不仅能够在一定 程度上取代心电图， 而且能够发展一些新的心脏功能监测的用途。  (1) The position of the sensor sticking is easy to determine, no special personnel are required to operate; (2) the sensor can directly contact the human body, no additional electrode is needed; (3) the sensor can be repeated and used for a long time without side effects on the body and skin; 4) Does not affect the normal life and work of the user; (5) It can be continuously monitored for a long time, which helps early detection of heart disease and early warning of cardiac function in patients with heart disease; (6) Provides a study for cardiac function research New approaches can not only replace ECGs to a certain extent, but also develop new uses for cardiac function monitoring.
基于本发明方法的心脏功能监测仪器， 通常只需采用一个传感器， 使 用非常简单， 只需要将这个传感器粘贴在人体体表 （通常在胸前） 即可。  The cardiac function monitoring instrument based on the method of the present invention usually requires only one sensor, and is very simple to use, and it is only necessary to attach the sensor to the body surface (usually on the chest).
