Google files a patent for a smartwatch capable of performing a blood glucose test

It is not news that medicine is one of the sciences that best uses technological advances. This time, the novelty should benefit the more than 400 million d all around the world. That's because Google has filed a formal application for a patent on a SmartWatch (smart watch) that would allow the user to take a small sample of blood without the use of needles, as well as help diabetics more easily monitor their glucose levels without the need to prick their finger, making the process easier and painless.

Since the patent application is still pending, Google has revealed little about the operation of the alleged device, as well as its potential uses or even when or how it will be produced. However, the initial draft indicates that the idea is to create a blood collection system that works by sending a gas that contains microparticles capable of puncturing the skin. In this way, once the blood is released through the skin, it is “sucked” back into the device through negative pressure.

No patent application Google claimed that "a tool of this type can be used to generate a small amount of blood, for example enough to carry out a blood glucose test". According to the diagrams disclosed with the patent application, the device would have the form of a small cylindrical tube that would be housed in a kind of watch, to be transported, but that would be removed from the watch after its use.

Google has a number of patents in the medical and healthcare fields, such as smart contact lenses and blood glucose monitors. Even if it manages to patent the idea, there is no prediction of how (or if) Google will even create the device. In an interview with the portal The Verge a company source stated that “although we have patents of the most varied ideas, some of them mature and become real products, others never go beyond ideas”.
