 應用於醫療之RF技術

What's Next For RF In Medicine?

RF Globalnet
August 19, 2016

Radio frequency and microwave technology often are thought of solely as communications tools, but their medical applications continue to expand.

Before looking at where we’re headed, though, let’s look at some of the staples that have defined RF use in medtech. The technology has been applied to surgery, imaging, and inter-device communications, to name just a few applications.

RF ablation technology uses RF energy to destroy unwanted tissues through a minimally invasive procedure. It can be used to eradicate cells with abnormal electrical activity — preventing arrhythmia (irregular heartbeat) — when delivered via a catheter, or to address tumor growth. Ablated tissue is replaced by healthy tissue through the body’s natural healing process.

In RF neurotomy/rhizotomy, generally used to treat back or neck pain, heat generated by radio waves targets specific nerves and temporarily interferes with their ability to transmit pain signals. This therapy can be used in addition to, or in lieu of, physical therapy and pharmaceuticals.

Magnetic resonance imaging (MRI) images the body’s anatomy (primarily water and fat) and physiological processes using strong magnetic fields, radio waves, and electrical field gradients.

Of course, communication still forms the backbone of RF technology’s utility in medicine. From pacemakers and subcutaneous implantable defibrillators (S-ICDs) that communicate with one another inside the body, to the practice of telemedicine in rural areas of large nations, leveraging RF technology to transmit/receive information continues to make its mark in medtech.

So, what’s next?

Unsurprisingly, as the Internet of Things permeates consumer devices, medtech has been on the leading edge of the trend. Connected medical devices make telemedicine feasible and effective, empower caregivers and allow patients to take a more active role in their care, and reduce healthcare ecosystem costs by minimizing doctor visits (often by transmitting data gathered by “smart” monitoring devices directly to doctors).

This trend runs the gamut of medical devices, many of which are aimed at home use. The world’s first Bluetooth-connected insulin pen launched in Europe this month and is expected to receive FDA approval in the U.S. later this year, and a Bluetooth-enabled, touchless thermometer launched in the U.S. earlier this summer.

Other initiatives are reevaluating how RF is used in established medical technologies. For example, in 2013, researchers at Case Western Reserve University found a way to speed MRI’s imaging process by overlapping signals to create a magnetic resonance “fingerprint” (MRF) matched to tissue qualities. Then, this summer, researchers at NYU Langone Medical Center designed "Plug-and-Play MR Fingerprinting" (PnP-MRF). This innovation is a circling strobe light of many broadcast magnetic fields, versus MRF’s single-source radio wave pulses; it creates layers of images by pulsing radio waves separated by a few milliseconds. Dark spots present in one image may not be visible in the next, allowing for more complete images and paving the way toward table-top or even hand-held MRI devices, according to the researchers.

Also, traditional marking of cancerous breast lesions for removal involves the injection of radioactive materials or wire localization — wherein surgeons are directed by a wire that protrudes from the patient’s breast. But one company’s implantable “reflector,” available in the U.S. as of late last year, offers another option: radar localization. Studies suggest the method both is clinically effective and improves patient experience.

Even elective procedures are getting in on the action: Despite the devices’ technical limitations, RFID chip implants offer a number of intriguing options. They have proven capable of navigating the FDA approval process, having (briefly) been leveraged to verify identity and medical history. One day, RFID implants may again fill that role, providing medical professionals with vital medical history information on-the-spot. But first, misinformation like the notion of governments tracking citizens through their RFID chips has to be dispelled from the public consciousness.

More realistic RFID implant applications include an Ohio implant company’s initiative to monitor strain on its spinal fusion rods using RFID technology. Numerous tissue-integrated health monitoring devices also are in development, many of which use RFID technology to communicate with a smartphone app, allowing users to track key biomarkers in real time.

The bottom line is, design engineers are stretching their wings as they look at unmet therapeutic needs. Even with the hurdles of FDA regulation, cybersecurity concerns, and the labyrinthine world of spectrum allocation, there is so much RF-related innovation in medtech right now, it’s difficult to pick and choose what to mention here.

 電子代工廠 強攻醫聯網 二至三倍的薪水攬才

2016-08-29 經濟日報

仁寶(2324)、廣達、緯創為甩開電子代工業「毛三到四(毛利率3至4%)」泥淖,近來積極進軍醫聯網領域,搶攻智慧衣、遠端照護、生物科技等市場,今年可望陸續收割成果,明年開始顯著貢獻營收,藉此力拚轉型。

仁寶全力搶攻醫療市場,今年起特別成立新部門「健康醫療事業部」,將相關人才集中,進行產品研發與製造,並攜手國內醫療設備廠凱建、源星、摩百、大寶共同搶進商機。

仁寶去年中宣布攜手長庚醫院成立「健康照護科技研發中心」、共同研發智慧衣,並斥資4.95億元取得工業電腦廠安勤20.54%股權,加強醫療產品製造研發實力。

仁寶智慧衣業務已接獲數家歐美運動品牌客戶大訂單,最快今年第3季起大量出貨。仁寶指出,智慧衣是未來物聯網關鍵應用,有信心五年之內成為繼筆電之後,集團下一個年營收千億元的明星級產品。

廣達則與麻省理工學院協同研發的QOCA醫療平台,力推「智慧床邊照護系統」、「遠端健康照護系統」,提供國內外大型醫院相關產品,目前已有中國醫藥大學附屬醫院、亞洲大學附屬醫院採用。

緯創方面,該公司今年初通過擬於不超過3億股額度內,以私募方式發行新股,因應未來轉型需求。緯創指出,此舉目的在於為整合緯創在醫療,及軟體應用的相關投資,透過新資金設立緯創生技投資控股公司、緯創數位投資控股公司,目前都已開始展開布局,今年底前會有新進度對外公告。

二至三倍薪 代工廠搶醫療人才
2016-08-29 聯合報

物聯網趨勢興起,遠距離醫療需求快速增溫,不少電子業者搶食商機,仁寶、廣達等代工廠為切入醫聯網與遠端醫療照護市場,今年開始招募具醫學背景的人才,並且開出優於一般資訊科技(IT)工程師二至三倍的薪水攬才,以利拓展市場。
仁寶、廣達、緯創為甩開電子代工業「毛三到四(毛利率百分之三到四)」泥淖,近來積極轉型搶攻智慧衣、遠端照護、生物科技等市場,今年可望陸續收割成果,明年開始顯著貢獻營收,對相關人才的需求也不斷增加。

雖然醫療市場量能無法與消費型電子產品比擬,但客製化程度及產品單價較高,成為台灣業者眼中的明星產業,也是代工業者轉型看好的藍海市場。

仁寶今年特別成立新部門「健康醫療事業部」,逾三分之一都具備醫療學識背景,與IT人才合力研發產品與製造,並攜手醫療設備廠凱建、源星、摩百、大寶共同搶進商機。

仁寶去年也已宣布攜手長庚醫院成立「健康照護科技研發中心」、共同研發智慧衣,並且斥資近五億元取得工業電腦廠安勤二成多的股權,加強醫療產品研發實力。仁寶指出,智慧衣是未來物聯網關鍵應用,最快第三季起大量出貨,有信心五年內成為繼筆電後,集團下一個年營收千億的明星產品。

廣達則與麻省理工學院協同研發醫療平台,力推「智慧床邊照護系統」、「遠端健康照護系統」,提供國內外大型醫院相關產品,目前已有中國醫藥大學附屬醫院、亞洲大學附屬醫院採用。

市場傳出,由廣達代工的第二代Apple Watch將設置前鏡頭,讓用戶視訊通話,並導入可監測血壓、血氧、皮膚電位的晶片,讓穿戴式裝置的應用,從「健康」邁向「醫療」,引發市場無限聯想。

業者透露,電子代工廠跨足醫療領域最關鍵就是人才,初期招募人才時,的確遭遇許多阻礙,包括醫療背景人才對於電子業興趣缺缺,而且在薪資方面也有所差距。其中,薪資還可以透過增加人事預算來解決,但興趣不高的問題則較為挑戰,可藉由建構醫療網的方式,讓人才得以學以致用。

 電子業大咖 搶攻數位醫療

2017-05-21 聯合報

看好全球二三○○億美元市場,台灣電子業大陣仗搶進「數位醫療」,今天起將與八國、廿一家數位醫療新創公司洽談合作,出席的國內大廠包括台積電、鴻海、群聯、友達、宏痋B廣達、台達電、緯創、聯發科等公司,這也是國內首度有如此大規模的一線電子大廠,共同轉進生醫領域,三年內累計投資額度可望突破百億元。

不僅電子大廠搶數位醫療商機,今天也有國際大型創投來台找生醫新秀,包括新加坡國家基金淡馬錫旗下生醫基金Vertex、亞洲富豪李嘉誠長江實業旗下基金Horizon,都會來台參與「數位醫療」創新公司選秀。三方將洽談資金、製造開發與人才等領域的結盟。

其中,Vertex與Horizon,前者是新加坡主權基金淡馬錫旗下,專注創新與生醫投資的基金,而Horizon則隸屬於李嘉誠所創辦的長江實業,主要投資領域在數位與科技領域。國內創投參與者包括中華開發、中經合、華威、心元資本等。

生醫產業已經是各國必爭領域,其中已成熟的數位科技結合醫療領域更是當代顯學。根據統計,美國近三年累計投資數位醫療投資的額度逾一三二億美元,年平均投資額約四十四億美元(約台幣一三二○億元),超過我政府一年的科技預算(我國明年科技預算編列一一一一億元)。

這次生醫選秀會,由時代基金會與「行政院國家發展委員會」共同主辦,今年首度以「Digital Health」(數位醫療)為主題,今起至六月二日共十天,共有廿一家數位醫療新創企業來台備選;其中台灣有五家新創生醫公司入列,包括AMA Medical、智創生醫、QT Medical、DNArails、浩宇生醫,為此次大會亮點。

數位醫療領域包括基因定序、大數據分析、穿戴式生物感測裝備,遠距醫療、數位醫療裝置、健康管理等。根據統計,三年內全球數位醫療市場將超過二三○○億美元(約台幣七兆元),去年在美國數位醫療投資額度前三名,分別是基因定序四點一億美元、大數據三點四一億美元,智慧穿戴生物感測系統三點一二億美元。
