Google patents an alternative way to test blood without a needle

Various "smart" watches are already able to determine the heart rate, the amount of required load and even the level of stress of a person. A number of other important parameters will soon be added to this list - thanks to a new method for determining the composition of blood without the "traditional" pricking of a finger, patented by Google.

Its principle of operation is based on the creation of a gas pulse sent through a special barrel containing microparticles. A jet of gas pierces the skin, captures a tiny drop of blood and, under the influence of negative pressure, sucks it into the device.

The whole process is absolutely painless and does not pose a threat of infection. Google also suggests using the technology as a blood glucose meter for diabetics.

In recent years, Google, along with its competitor - Apple, has been actively developing the field of wearable medical devices. The company already has patents for smart lenses, "cloud" sensors that provide care for patients with diabetes and other medical devices. The main goal of the Internet giant in this direction is to bring together the maximum indications of a person's health in one device.
