指尖式血氧儀拆解:揭示個人醫(yī)療設備未來

在 DesignMed 2011 大會上,透過拆解 Nonin Onyx II 9560 指尖式血氧儀(pulse oximeter),工程師們可一窺未來個人醫(yī)療設備的發(fā)展風貌。

在 DesignMed 2011 大會上,透過拆解 Nonin Onyx II 9560 指尖式血氧儀(pulse oximeter),工程師們可一窺未來個人醫(yī)療設備的發(fā)展風貌。 “從放置在桌上的大型系統(tǒng)演變至今天護士能隨身攜帶的小型設備,Nonin 早已預見了未來人們對小型、簡便的醫(yī)療設備的的需求,”前Nonin Medical工程副總裁Bill Betten說。 Onyx系統(tǒng)讓原先專用于醫(yī)療院所中的裝置變?yōu)楦m合個人應用的消費性醫(yī)療設備。 “在不久的將來,我們會看到許多技術陸續(xù)問世,如可測量人體參數(shù)的耳機、可穿戴式傳感器、胸帶,以及其它各式各樣的設備,都將出現(xiàn)在專業(yè)的醫(yī)療領域之中,”Betten說。Betten目前是《EE Times》母公司UBM LLCs旗下UBM TechInsights醫(yī)療部門的資深顧問。 來自快速成長的消費電子領域的先進顯示屏幕、處理器和用戶接口軟件,目前也正開始進入醫(yī)療電子領域,過去,醫(yī)療設備一直專注于發(fā)展后緣(trailing edg)組件,而且設計和審核的周期都非常長,Betten說。這將激發(fā)出“文化上的根本沖突,”他表示。 “發(fā)展腳步太迅速了,以致你很難確實追蹤,”他說。另一方面,植入式醫(yī)療設備的低功耗和微型封裝技術,也很有可能回流在未來的某一天回流到消費市場,他補充道。 拆解Nonin的設備,便會發(fā)現(xiàn)它使用了恩智浦(NXP)的微控制器(MCU)和飛思卡爾 (Freescale)的8位MCU,UBM TechInsights的技術智財部副總裁David Carey說。 Nonin使用專有的信號處理技術,以獨特的方法來放大并訊節(jié)光信號,因此,他們聲稱可以使用低功耗的消費級處理器,Betten說。9560這款產(chǎn)品將藍牙(Bluetooth)收發(fā)器內(nèi)置在系統(tǒng)的電池組中,以節(jié)省空間,他表示。 這次的 DesignMed大會將以‘行動’為主軸。德州儀器(TI)的工程師也將回顧個人保健設備的發(fā)展,并探討無線技術在醫(yī)療設計中的影響程度。此外,業(yè)界專家也將展示如何獲得醫(yī)療保健監(jiān)管機關的核準。 DesignMed大會也邀請到麻省理工學院(MIT)教授Charles G. Sodini進行主題演講,他針對醫(yī)療電子進行了廣泛調(diào)查,包括創(chuàng)新的可穿戴式設備,以及通訊技術等。 編譯: Joy Teng 本文授權(quán)編譯自EE Times,版權(quán)所有,謝絕轉(zhuǎn)載 參考英文原文: Consumer meets medical in ESC teardown,by Rick Merritt

{pagination} Consumer meets medical in ESC teardown Rick Merritt SAN JOSE, Calif. – Engineers will get a glimpse into the future of personal health care devices at DesignMed 2011 where experts will tear down a Nonin Onyx II 9560 fingertip pulse oximeter, a system that helped pioneer the emerging field. The teardown is one of a handful of sessions at the ESC Boston event exploring the horizon in personalized medicine. "Nonin saw a need for something small and simple taking medical devices from tabletop systems to handheld units nurses can carry around with them," said Bill Betten, the former vice president of engineering at Nonin Medical who will be in the audience for the teardown. The Onyx system is a regulated device geared for use in hospitals, but helped forge the way for consumer medical devices that face less stringent regulations. "In the not-too-distant future we'll see a lot of neat technologies like headsets that measure body parameters, body-worn sensors, chest straps and a lot of things that creep up to the edge of the professional medical world," said Betten, now a senior advisor for the medical group at UBM TechInsights, part of UBM LLCs, the publisher of EE Times. The sophisticated displays, processors and user interface software of the fast-moving consumer sector are invading the medical electronics field that has been focused on trailing edge components and long design and approval cycles, Betten said. That's creating "a fundamental clash of cultures," he said. "It's all evolving so rapidly it's hard to keep track of it," he said. On the other hand, the low power and miniature packaging technology of medical implants is likely to flow back into consumer markets someday, he added. The Nonin teardown will reveal a device using tried and true components including an NXP micrcontroller and a Freescale 8-bit MCU, said David Carey, vice president of technical intelligence at UBM TechInsights who will open up the device. It is one of about 13 medical device teardowns the group has done to date. Nonin used signal processing expertise to amplify and condition light signal in unique ways so they could use low-power, consumer-grade processors, said Betten. The model 9560 builds a Bluetooth transceiver into the system's battery pack to save space, he added. Mobile will be the theme of a handful of DesignMed sessions. Texas Instruments engineers will review the landscape of personal health care devices and talk about the impact wireless is having in medical design. Separately, a consultant will show how to get regulatory approval for health care apps. The program also includes a keynote from MIT professor Charles G. Sodini who will survey the broad landscape in medical electronics, including innovations in wearable and communicating devices.
