Description
技术领域technical field
本发明属于医疗设备领域，具体来说，是可穿戴式的人体体温、血氧、心率监测终端。The invention belongs to the field of medical equipment, in particular, it is a wearable monitoring terminal for body temperature, blood oxygen and heart rate.
背景技术Background technique
生命体征就是用来判断病人的病情轻重和危急程度的指征，主要有心率、脉搏、血压、呼吸、瞳孔和角膜反射的改变等等。其中体温、呼吸、脉搏和血压被称为人体四大生命体征。医护人员只有通过全面了解生命体征的意义并及时掌握病人生命体征的变化，才能在第一时间采取有效的救治措施。统计的生命体征病理数据可以作为医生临床诊断的数据支撑，对降低患者的死亡率有很大的帮助。因此，人体生命体征的检测和监测必将发展成为不可或缺的学科。Vital signs are indicators used to judge the severity and criticality of a patient's condition, mainly including changes in heart rate, pulse, blood pressure, respiration, pupillary and corneal reflexes, and so on. Among them, body temperature, respiration, pulse and blood pressure are called the four vital signs of the human body. Only by comprehensively understanding the meaning of vital signs and timely grasping the changes of patient's vital signs, can medical staff take effective treatment measures in the first place. Statistical vital signs and pathological data can be used as data support for doctors' clinical diagnosis, which is of great help in reducing the mortality of patients. Therefore, the detection and monitoring of human vital signs will surely develop into an indispensable subject.
便携式微型化设计可以方便个人、家庭的检测和检测，对我国因疆域辽阔导致的医疗资源分布不均衡问题可以起到一定的缓解作用，使其具有更广阔的市场空间，如何在保证其性能的前提下缩小设备体积，这对我们各种控制芯片和制造工艺是个极大的考验。多参数智能化设计则使得对生命体征的检测和监测更加全面便捷，符合当今社会快节奏的生活步伐和智能机时代的要求。The portable miniaturized design can facilitate personal and family testing and testing, and can play a certain role in alleviating the uneven distribution of medical resources caused by the vast territory of our country, so that it has a broader market space. How to ensure its performance? Reducing the size of the equipment under the premise is a great test for our various control chips and manufacturing processes. The multi-parameter intelligent design makes the detection and monitoring of vital signs more comprehensive and convenient, which meets the requirements of the fast-paced life in today's society and the era of smart machines.
目前生命体征检测最常见的方式就是通过电极或者传感器接触人体采集信号，容易对人体施加一定刺激，既对病人的生命安全产生威胁，又容易影响检测结果的准确性，且对于精神错乱、身体大面积烧伤等情况，无法用接触式检测的方式直接进行检测。因此研究不影响用户正常工作和生活的非接触式生命体征检测应运而生，但此类技术目前不太成熟，还需要进一步探索和研究，最终实现无创检测人体的生理信号。At present, the most common way to detect vital signs is to collect signals by contacting the human body with electrodes or sensors. Surface burns and other conditions cannot be directly detected by contact detection. Therefore, research on non-contact vital sign detection that does not affect the normal work and life of users has emerged as the times require. However, this type of technology is not yet mature, and further exploration and research are needed to finally realize non-invasive detection of human physiological signals.
未来人体生命体征的检测和监测必然会向微型化便携式发展，而电池和功耗几乎是所有移动设备都不能忽略的问题。虽然嵌入式微处理器本身具有低功耗特点，当其嵌入到宿主系统以后其功耗就不得不考虑，因此真正做到低功耗成为未来生命体征检测需要不断面对的问题。至于电池，由于该类检测设备多大需要和人体接触，在如今苹果手机多次因电池出现事故后，移动设备电池的安全性是首要考虑的问题，其次才是其容量、体积和充电效率等因素。这些无疑都会成为未来人体生命体征的检测和监测会遇到的苦难和挑战。In the future, the detection and monitoring of human vital signs will inevitably develop towards miniaturization and portability, and battery and power consumption are issues that cannot be ignored by almost all mobile devices. Although the embedded microprocessor itself has the characteristics of low power consumption, its power consumption has to be considered after it is embedded into the host system. Therefore, truly achieving low power consumption has become a problem that needs to be constantly faced in future vital sign detection. As for the battery, since this type of testing equipment needs to be in contact with the human body, the safety of the battery of the mobile device is the primary consideration after many battery accidents in Apple mobile phones, followed by factors such as its capacity, volume and charging efficiency. . These will undoubtedly become the hardships and challenges that will be encountered in the detection and monitoring of human vital signs in the future.
在远程生命体征监测领域国内一些重点高校如清华大学、山东大学和台湾各大学对于远程医疗的应用实现做出了研究，获得了一些成果。但能够真正推广成家用普及型产品的成果仍然没有。究其原因，主要是用户体验不佳，系统设计不完善，相关医院也没有一个综合数据平台作为支撑。政府层面也没有投入大的资金建立一个综合信息服务平台，造成了今天我们每个人的生命体征数据档案仍然为空白。In the field of remote vital signs monitoring, some domestic key universities such as Tsinghua University, Shandong University and various universities in Taiwan have made research on the application of telemedicine and achieved some results. However, there are still no results that can really promote popular products for household use. The main reason is that the user experience is not good, the system design is not perfect, and the relevant hospitals do not have a comprehensive data platform as a support. The government has not invested a large amount of money to establish a comprehensive information service platform, resulting in the fact that the vital sign data files of each of us are still blank today.
既适用于医院又适用于家庭和个人的人体生命体征监测手机系统具有人体生理信号检测和处理、信号特征提取和数据传输等功能，可以实现对人体的无创监测、诊断。具有可移动操作、使用简便、支持长时间连续工作、智能显示诊断结果、异常生理状况报警和无线数据传输等特点。此系统是穿戴式辅助医疗的发展方向，是基于生物医疗、计算机科学、通讯技术等多学科的产品，是将移动计算、医学传感以及通信技术等密切结合的一种新兴辅助医疗保健模式。The human vital signs monitoring mobile phone system, which is suitable for both hospitals and families and individuals, has the functions of human physiological signal detection and processing, signal feature extraction and data transmission, etc., and can realize non-invasive monitoring and diagnosis of human body. It has the characteristics of mobile operation, easy to use, long-term continuous work support, intelligent display of diagnostic results, abnormal physiological status alarm and wireless data transmission. This system is the development direction of wearable auxiliary medical care. It is a multidisciplinary product based on biomedicine, computer science, and communication technology. It is an emerging auxiliary medical care model that closely combines mobile computing, medical sensing, and communication technology.
