技术领域technical field
本发明涉及疾病监控技术领域，尤其涉及一种基于心电检测与血压监测的智能袖套。The invention relates to the technical field of disease monitoring, in particular to an intelligent cuff based on electrocardiogram detection and blood pressure monitoring.
背景技术Background technique
随着我国老龄化的趋势越来越明显，老龄化所带来了一系列问题也愈发显著，首先体现在一些疾病的发生率逐年攀升，其中就包括心脏病，高血压等其他疾病。但是由于老年人行动不便，使得他们前往医院看病十分不便。因此，远程医疗将在未来成为医疗体系服务中很重要的一部分。As the trend of aging in our country becomes more and more obvious, a series of problems brought about by aging are also becoming more and more obvious. Firstly, the incidence of some diseases is rising year by year, including heart disease, high blood pressure and other diseases. However, due to the inconvenience of the elderly, it is very inconvenient for them to go to the hospital to see a doctor. Therefore, telemedicine will become an important part of the medical system services in the future.
心脏病，高血压是造成人类死亡的主要疾病之一。体表心电信号和血压信号是生理状态的反映。到目前为止，心脏病与高血压的检测主要是基于医院的大型诊疗设备。但是，心脏病的发病具有偶然性，突发性和一过性。因此，有必要对患者进行长时间的随身疾病监控。可移动的无线检测设备能够对患者的生理状态进行长期的监护，在其发病时能够提供及时的报警，获得尽快的救治。Heart disease and high blood pressure are one of the main diseases causing human death. Body surface ECG signal and blood pressure signal are the reflection of physiological state. So far, the detection of heart disease and high blood pressure is mainly based on large-scale diagnosis and treatment equipment in hospitals. However, the onset of heart disease is accidental, sudden and transient. Therefore, it is necessary to carry out long-term follow-up disease monitoring on patients. The mobile wireless detection equipment can monitor the patient's physiological state for a long time, and can provide timely alarm when the disease occurs, so as to obtain as soon as possible treatment.
当前心电检测设备主要分为两种，一种是大型固定的心电检测设备，这种设备检测效果好，校测结果全面稳定，但是不可移动，不能做到一般病人在正常日常生活中的实时监控。The current ECG detection equipment is mainly divided into two types, one is large fixed ECG detection equipment, which has good detection effect and comprehensive and stable calibration results, but it cannot be moved and cannot be used by ordinary patients in normal daily life. real time monitoring.
另外一种主要的心电检测设备是移动监测设备，当前很多是基于手环，这种设备存在电极片与皮肤接触不良的问题，当患者处于运动状态，手环难以稳定在皮肤表面，会引入较大误差。除此之外，对于不同胖瘦人群，手环的大小难以调整，对于较瘦的人，难以保证电极片与皮肤紧密接触。Another major type of ECG detection equipment is mobile monitoring equipment, many of which are currently based on wristbands. This kind of equipment has the problem of poor contact between the electrodes and the skin. large error. In addition, for different fat and thin people, the size of the bracelet is difficult to adjust, and for thinner people, it is difficult to ensure that the electrodes are in close contact with the skin.
而且，现在存在的可移动穿戴设备检测技术中，更多的是基于心率监测的，对于心电图的检测的设备几乎没有，这是因为心电图检测一般不能仅仅从一处采集心电信号。而心电图中所包含的信息，是远远大于心率检测所包含的信息的，可以从心电图对患者的近期疾病情况有一个完整的认识。Moreover, most of the current detection technologies for mobile wearable devices are based on heart rate monitoring, and there are almost no devices for ECG detection, because ECG detection generally cannot only collect ECG signals from one place. The information contained in the electrocardiogram is far greater than that contained in the heart rate detection, and a complete understanding of the patient's recent disease conditions can be obtained from the electrocardiogram.
除此之外，现在存在的设备中，还存在续航能力不足的问题。目前的方式主要是基于纽扣电池或者蓄电池进行供电，存在续航能力短，无法做到不间断监护病人，若病人在设备停电或者正在充电时，突发意外情况，难以起到监护并报警的作用；如果购买两个设备，又会增加患者经济负担。In addition, there is still the problem of insufficient battery life among the existing devices. The current method is mainly based on button batteries or batteries for power supply, which has a short battery life and cannot monitor patients continuously. If the patient encounters an unexpected situation when the device is powered off or charging, it is difficult to monitor and call the police; If two devices are purchased, the financial burden on patients will be increased.

The power management module can use human body heat to charge the battery, and can also use wireless charging to charge the battery, and ensure that the battery will not be damaged due to improper charging. The power management module can also record the remaining battery power during use, and can also turn off the power supply of the system when the battery power is too low to ensure the normal operation of the system.
整体系统工作过程如下：整体系统工作过程如下：i.安装上电池后，处理器控制模块开始工作，且处于低功耗休眠状态。此状态下除了处理器控制模块和供电模块外，其它模块处于休眠状态。ii.当开关按下后，触发微处理器控制模块的中断，此时，整个系统进入工作模式，所有系统都开始工作。iii.在工作模式中，信号采集模块会将人体表面微弱的心电信号和血压信号经过外围电路做预处理，经AD转换为数字信号后传输至处理器控制模块，经过处理后传输给无线收发模块，由无线收发模块发送至手机终端或云端服务器。The working process of the overall system is as follows: The working process of the overall system is as follows: i. After the battery is installed, the processor control module starts to work and is in a low-power sleep state. In this state, except for the processor control module and the power supply module, other modules are in a dormant state. ii. When the switch is pressed, the interrupt of the microprocessor control module is triggered. At this time, the whole system enters the working mode, and all systems start to work. iii.
