【摘要】：血壓是反映心臟和血管功能狀況的重要參數(shù),無創(chuàng)、準確的血壓連續(xù)監(jiān)測便攜式系統(tǒng)能提高血壓監(jiān)測的舒適性與便捷性,從而有助于心血管疾病的預防和診斷。根據(jù)血壓連續(xù)監(jiān)測需求,設計一套基于Android平臺的無創(chuàng)血壓連續(xù)監(jiān)測系統(tǒng)。該系統(tǒng)由前端信號采集系統(tǒng)和手機端App構成,可實現(xiàn)心電、脈搏信號的同步采集。用手機端App實時繪制兩路波形,計算出脈搏波傳導時間PWTT和脈搏波波形特征量K,建立血壓回歸模型,計算血壓值,并對血壓的變化進行圖表分析。實驗結果表明,所設計的無創(chuàng)血壓監(jiān)測系統(tǒng)測量的血壓絕對誤差均小于8 mm Hg,標準誤差小于5 mm Hg,App界面簡單易操作,用戶通過隨身攜帶的手機就能隨時查看自己身體健康狀況變化,達到預防高血壓疾病和及時問醫(yī)的目的。
[Abstract]:Blood pressure is an important parameter to reflect the function of heart and blood vessel. The accurate portable system of continuous monitoring of blood pressure can improve the comfort and convenience of blood pressure monitoring, which is helpful to the prevention and diagnosis of cardiovascular diseases. According to the requirement of continuous blood pressure monitoring, a non-invasive blood pressure monitoring system based on Android platform is designed. The system consists of a front-end signal acquisition system and a mobile phone terminal App, which can realize the synchronous acquisition of ECG and pulse signals. The pulse wave conduction time (PWTT) and pulse wave characteristic value (K) were calculated by using mobile phone terminal App. The blood pressure regression model was established, and the blood pressure value was calculated, and the change of blood pressure was analyzed. The experimental results show that the absolute error of blood pressure measured by the designed non-invasive blood pressure monitoring system is less than 8 mm Hg, and the standard error is less than 5 mm. The interface of the system is simple and easy to operate. Users can check their health changes with their mobile phones to prevent high blood pressure and ask doctors in time.
