These two devices could help save your life.
Researchers at George Washigton University in Washington DC have been working on medical tools to speed up the process of diagnosing some health problems.
The first, a device named “a tricorder”, can test blood, urine and saliva samples.
This chip contains a complex liquid network to test those fluids.
The diagnostic results are forwarded to a Smartphone app, says the inventor of the device.
“And the goal of this is to bring accessibility, put this thing in potentially a physician's office, or even in the patient's home.
And then also the speed.
You can get the results at least within hours, if not minutes.”
The second invention is worn like a piece of jewelry-a flexible ring embedded with a wireless electrocardiogram sensor that can also diagnose heart irregularities, as well as other conditions.
Like the tricorder, the results are delivered to your phone app, or directly to your doctor.
"I think a ring is really the only thing that people wear all the time and also it's relatively stable compared to other format, like a wristband or watch.”
But some people may not like this do-it-yourself health care.
"There are people who are not comfortable, don't like this kind of, putting sensors on their body.
But for people who have chronic conditions, who are sometimes at risk of, for example, heart attacks, this type of device could be useful and life-saving.”
Both diagnostic tools could be in the hands of doctors and patients within just a few years.
