【摘要】：醫(yī)療與保健一直以來都是人們關(guān)心的主題，在追求高質(zhì)量生活的現(xiàn)代社會中，人們越發(fā)清醒地認識到健康的重要性。然而，現(xiàn)在的人們大多處于亞健康狀態(tài)。應社會的需求，便攜式醫(yī)療監(jiān)護儀器正在逐漸地走進人們的家庭生活。這種醫(yī)療監(jiān)護儀也迎合了人們早發(fā)現(xiàn)早治療的心理，并且促進了人們加強身體鍛煉。便攜式醫(yī)療設(shè)備已經(jīng)不是個新名詞，，它正處在高速發(fā)展的狀態(tài)中。上市的醫(yī)療監(jiān)護產(chǎn)品，能夠滿足人們的醫(yī)療監(jiān)護需求，但是由于受到成本、體積以及易操作性等條件的制約，并沒有大幅度地被人們所接受。除此之外，這些產(chǎn)品的使用環(huán)境約束了設(shè)備的便攜性。外加一些輔助監(jiān)護的附件，這更增加了使用者的煩惱。在不失測量精度的前提下，如何使得醫(yī)療監(jiān)護設(shè)備真正達到其便攜性、多功能性以及穩(wěn)定性，這將成為人們進一步努力研究的方向。本論文在這一研究方向上做出了相關(guān)設(shè)計，所設(shè)計的儀器是一種軟、硬件一體化多功能便攜式醫(yī)療監(jiān)護設(shè)備，其測量參數(shù)主要包括心電圖（ECG）、光電容積脈搏波（PPG）、血氧飽和度（SpO2）、體表溫度以及人體動作信號（加速度信號）等。該監(jiān)護儀不受測量場地限制，體積小巧，成本低廉，并具有較高的穩(wěn)定性。 本論文的系統(tǒng)設(shè)計主要分為兩個部分，硬件功能模塊搭建和微處理器軟件處理。硬件方面，首先是電源模塊，既可以外接電源，也可以內(nèi)接電池。其次是功能模塊，包括心電采集模塊、脈搏采集模塊、體表溫度采集模塊、人體動作信號采集模塊。最后是信號處理模塊，包括顯示和傳輸。論文根據(jù)有用信號頻譜設(shè)計濾波器、放大器以及陷波器等，并且為硬件接口設(shè)計驅(qū)動程序，包括DS18B20、ADXL345、液晶屏等。軟件方面，根據(jù)兩路脈搏的交直流信號，利用朗伯-比爾公式算出人體的血氧飽和度；根據(jù)人體加速度信號，利用最小均方誤差法削弱乃至消除人體移動時對系統(tǒng)帶來的運動偽跡；根據(jù)人體加速度信號，使用動態(tài)閾值和滑動窗等技術(shù)，設(shè)計一款計步器，分析出人體運動時所走的步數(shù)。
[Abstract]:Medical care and health care have always been the subject of concern. In a modern society that pursues a high quality of life, people are increasingly aware of the importance of health. However, most people nowadays are in a state of sub-health. Portable medical monitoring devices are gradually entering people's family life. This medical monitor caters to early discovery of early treatment and promotes physical exercise. Portable medical devices are no longer a new term. It is in a state of rapid development. The marketed medical monitoring products can meet the needs of people, but due to the cost, volume and ease of operation and other conditions, Besides, the use environment of these products restricts the portability of the device, and some auxiliary monitoring accessories add to the trouble of the user. Without losing the accuracy of the measurement, How to make the medical monitoring equipment achieve its portability, versatility and stability will become the direction of further research. This paper has made the related design in this research direction, the instrument designed is a kind of soft, Hardware integration multifunctional portable medical monitoring equipment, The parameters include ECG, PPG, SPO _ 2, body surface temperature and acceleration signal, etc. The monitor is small, compact and low cost. And it has high stability. The system design of this paper is mainly divided into two parts, hardware functional module building and microprocessor software processing. Hardware, first is the power module, can be connected to the external power supply, but also can be connected to the battery. Secondly, the function module. Including ECG acquisition module, pulse acquisition module, body surface temperature acquisition module, human body action signal acquisition module. Finally, the signal processing module, including display and transmission. The amplifier and notch filter are designed for the hardware interface, including DS18B20ADXL345, LCD screen, etc. In software, according to the AC / DC signal of two pulse channels, the oxygen saturation of human body is calculated by the formula of Lamber-Bill; According to the acceleration signal of human body, the minimum mean square error method is used to weaken and even eliminate the motion artifacts brought by the human body moving, and according to the acceleration signal of the human body, the dynamic threshold and sliding window techniques are used to design a pedometer. Analyze the number of steps the human body takes when it moves.
