NHS to launch 'intelligent' pill with edible microchip... that texts you if you have forgotten to take your next dose

Heart patients are to test the ultimate 'smart' pill - an edible microchip that delivers information about their body direct to a mobile phone.
心髒病人會測試那終極的'聰明'丸 - 一種可食用的晶片傳遞關於他們身體的信息直接到移動電話。
Around 40 people are being recruited by NHS doctors to take standard versions of their heart pills fitted with a microchip.
大約 40人被NHS招募，去服用標準版本裝置有一微型芯片的心丸。
The chips in the pills send signals to a patch attached to the patient's shoulder, which relays a text message to a mobile or hand-held device if they have forgotten to take their medication.
藥丸內的晶片發出信號至一塊附在病人肩膀上的貼片，它接力發出文本信息到移動或手握的裝置，如果他們已忘了吃藥。
The Raisin: The system contains a pill with an edible microchip and a patch that sits on the shoulder which texts information to either the doctor or patient
葡萄乾：系統包含一粒有可食用晶片的藥丸，和一塊放在肩膀上的貼片，它正文資料給醫生或病人
The system also monitors heart rate, heart activity and how well the patient is sleeping - all of which may signal a deteriorating condition - and costs just a few pence per patient.
系統亦監測心率、心臟活動以及病人睡眠如何好 - 所有這些都預示著可能惡化的情況 - 和每名病人成本只有幾便士。
The system, called Raisin, was initially tested in the US where it improved the level of compliance of patients taking their pills from 30 per cent to 80 per cent.
系統稱為葡萄乾，最初是在美國測試的，在那裡它提高患者服用藥片的順從水平，從百分之三十到百分之八十。
If successful, the four-month trial being run by Imperial College Healthcare NHS Trust, Imperial College London and the Royal Berkshire Hospital, Reading, could lead to a year-long NHS trial.
Professor Nicholas Peters, professor of cardiology at Imperial College Healthcare, said the main aim was to supply information to heart patients that would encourage them to take their pills.
As a result, their wellbeing would improve and they were less likely to be admitted to hospital as an emergency.
In the trial the patches will allow doctors to check whether patients have taken their pills, track the heart rate and determine whether they are frequently sitting up at night.
This can signal fluid on the lungs which means the dosage needs adjusting.
Prof Peters said 'The concept behind the technology is that the information belongs to the patient, who will be able to see the benefits of their medication in a number of measures.
'It will encourage patients to take responsibility for their own health. Heart failure is a condition where if the patient doesn't remain stable it can lead to a cascade of problems that results in emergency admissions into hospital.
'This is the kind of innovation that should help contain these costs. The hope is that after testing it can be appraised by the NHS and adopted for widespread use at an early stage.'
Dr Charlie McKenna, a consultant cardiologist at the Royal Berkshire, said 'I think it's very exciting. This approach has large potential to help with compliance.'
The chips developed by Proteus Biomedical, a California-based company, are tiny, digestible sensors made from food ingredients which are activated by stomach fluids after swallowing.
Once activated, the sensor sends an ultra, low-power digital signal through the body to a microelectronic receiver that is either a patch or tiny device inserted under the skin.
This decodes and records the information.
Manufactured on silicon wafers, the company says the sensors are extremely economical to produce costing a 'few cents' per sensor in large quantities.
The technology today received the European Union's CE mark, certifying that it meets consumer and health requirements.
It paves the way for the system to be combined with a range of medicines, and clinical trials have begun in the US with drugs for diabetes, organ transplants, mental health and tuberculosis.
Andrew Thompson, president and chief executive officer of Proteus, said CE mark approval was a 'major milestone for the advancement of intelligent medicine'.
He said 'The timing is very good - many government budgets are under financial pressure and our approach is one that promises better results with less spending and higher consumer satisfaction.
