新科技 Wifi信號(hào)能治病

Researchers have developed a method to activate electronic implants in the body and eliminate bacterial infections using a wireless signal.

研究者已經(jīng)開(kāi)發(fā)了一種運(yùn)用無(wú)線信號(hào)激活人體中電子植入物來(lái)消除細(xì)菌感染的方法。

When triggered by remote technology, the gadget delivers heat to infected tissue.

當(dāng)通過(guò)遠(yuǎn)程技術(shù)觸發(fā)時(shí)，那個(gè)小裝置就向被感染的組織傳遞熱量。

And it could lead to technologies that enable drugs and treatment to be delivered to patients at the press of a button.

一旦按下按鈕，它就能夠通向保證藥物和治療傳遞給病人的技術(shù)。

The technology was developed by researchers at Tufts University in Massachusetts and the University of Illinois.

這種技術(shù)是由美國(guó)馬薩諸塞州的塔夫茨大學(xué)和伊利諾斯大學(xué)的研究者開(kāi)發(fā)的。

Mice were given electronic implants that, when a signal was sent, heated up to treat tissue that was infected with staphylococcus, or staph, which can cause minor skinabscesses or life-threatening infections of the blood.

當(dāng)信號(hào)發(fā)出，小白鼠體內(nèi)的電子植入物就通過(guò)加熱來(lái)治療被葡萄球菌感染的組織，這種被感染的組織可能會(huì)引發(fā)輕微的皮膚膿腫或者威脅生命的血液感染。

Tissues collected from the mice 24 hours after treatment showed no sign of the infection, while the device dissolved in 15 days, proving it can not only treat infections but also bedisposed of easily.

在治療之后24小時(shí)內(nèi)從小白鼠身上收集到的組織已經(jīng)沒(méi)有感染的跡象了。這個(gè)裝置在15天內(nèi)自動(dòng)降解，這也證明它不僅能夠治療感染，同時(shí)也是很容易處理的。

The research, which also eliminated E. coli bacteria, was published in the Proceedings of the National Academy of Sciences.

這個(gè)同時(shí)也消除了大腸桿菌的研究被發(fā)表在美國(guó)國(guó)家科學(xué)院的會(huì)刊上。

Each device, made of silk and magnesium, harmlessly dissolved in the animals after the tests.

每個(gè)設(shè)備都是由絲和鎂制成，在實(shí)驗(yàn)結(jié)束后會(huì)自動(dòng)降解，對(duì)動(dòng)物的身體沒(méi)有傷害。

The heating device in the implants has a resistor and power-receiving coil made of magnesium, and the magnesium is wrapped in 'packet' of silk, keeping it safe and controlling its dissolution time.

植入物中的加熱設(shè)備有一個(gè)電阻器和一個(gè)電力接收線圈，線圈是由鎂制成的，而鎂的外表又包裹了一層絲，這樣既保證了安全又控制了其降解的時(shí)間。

The ability of the device to dissolve is important, as it means such implants would not need to be removed.

這個(gè)裝置的自動(dòng)降解能力是十分重要的，因?yàn)檫@意味著這種植入物不會(huì)再需要另外移除。

Implantable medical devices normally use non-degradable materials that have limited operational lifetimes and must eventually be removed or replaced.

植入式醫(yī)療設(shè)備通常使用的都是不可降解的材料，它們的的使用壽命有限，而且最終必須移除或者重置。

But these new wireless therapy devices can handle the surgical process, and can then dissolve in minutes or weeks, depending on the time needed.

但是這些新式的無(wú)線治療設(shè)備可以處理手術(shù)過(guò)程，而且能夠根據(jù)需求時(shí)間在幾分鐘或者幾周內(nèi)自動(dòng)降解。

"This is an important demonstration step forward for the development of on-demand medical devices that can be turned on remotely to perform a therapeutic function in a patient and then safely disappear after their use, requiring no retrieval," said senior author Fiorenzo Omenetto, professor of biomedical engineering at Tufts School of Engineering.

資深作家菲奧倫佐·澳門(mén)托——塔夫茨大學(xué)工程學(xué)院生物醫(yī)學(xué)工程的教授說(shuō)道：“對(duì)于需求式醫(yī)療設(shè)備的發(fā)展，這是重要的一步進(jìn)展。需求式醫(yī)療設(shè)備能夠在病人身上遠(yuǎn)程操作治療功能，而且治療完成后能夠安全降解，不需要再取出來(lái)。”

"These wireless strategies could help manage post-surgical infection, for example, or pave the way for eventual Wi-Fi drug delivery."

“比如，這些無(wú)線戰(zhàn)略可有助于處理術(shù)后感染或者為最終的無(wú)線藥物傳輸鋪平道路”。
