【摘要】：針對人口老齡化和醫(yī)療資源緊張問題,利用可穿戴設備和先進的物聯(lián)網(wǎng)技術將患者的生命體征信息隨時隨地傳送給醫(yī)護人員和醫(yī)療機構,使患者得到及時救治。因此,微型化、無線化、集成化和智能化的可穿戴設備越來越受到人們的關注。超高頻射頻識別技術(UHF RFID)是一種工作在860-960MHz的無線通信技術,具有成本和功耗低、抗干擾能力強的優(yōu)點,通過結合先進的傳感器技術可以進一步拓展其功能。然而,截止目前為止,關于UHF RFID技術在可穿戴設備中的開發(fā)應用并不多見。因此,開發(fā)一款基于UHF RFID技術的無線生命體征監(jiān)護系統(tǒng)對促進智慧醫(yī)療的發(fā)展和推動醫(yī)療行業(yè)的改革有著重要意義。本文提出一種基于UHF RFID技術的無線血氧脈搏監(jiān)測解決方案,完成了系統(tǒng)搭建和驗證,并對部分模塊進行了數(shù)字集成電路設計。其中系統(tǒng)整體架構由光電傳感器、數(shù)據(jù)處理模塊、RFID標簽、RFID閱讀器和上位機組成。光電傳感器和數(shù)據(jù)處理模塊實時采集和處理脈搏血氧信號,RFID標簽和閱讀器實現(xiàn)數(shù)據(jù)無線通信,最終通過上位機完成數(shù)據(jù)收集和界面顯示。系統(tǒng)功能驗證完成后對數(shù)據(jù)處理模塊進行了數(shù)字集成電路設計,完成RTL代碼的設計與優(yōu)化,并基于UMC0.18μm CMOS工藝進行了完整的后端物理設計,包括布圖、標準單元布局、時鐘樹綜合、布線和可制造性設計。經(jīng)過靜態(tài)時序分析、形式驗證、物理版圖驗證DRC和LVS的檢查后,芯片的時序問題與版圖的規(guī)則問題均得到修復。數(shù)據(jù)處理芯片版圖面積為693×693μm~2,核心區(qū)標準單元數(shù)為1704。實驗結果表明,所設計系統(tǒng)與臨床用血氧脈搏檢測儀具有良好的一致性,血氧飽和度和脈率的最大測量誤差分別為±1%和±2bpm且具有無線傳輸和低功耗的特點,為無線生物傳感芯片的設計開發(fā)提供了重要參考。

Therefore, miniaturized, wireless, integrated and intelligent wearable devices are attracting more and more attention. UHF radio frequency identification (UHF RFID) is a kind of wireless communication technology working in 860-960MHz, which has the advantages of low cost, low power consumption and strong anti-interference ability. By combining with advanced sensor technology, its function can be further expanded. However, so far, the development and application of UHF RFID technology in wearable devices is rare. Therefore, it is of great significance to develop a wireless vital sign monitoring system based on UHF RFID technology to promote the development of intelligent medical care and the reform of medical industry. In this paper, a wireless oxygen pulse monitoring solution based on UHF RFID technology is proposed. The system is built and verified, and some modules are designed with digital integrated circuit.
