Google’s New Needle free blood draw system

Written by Jana Raj

We all know that Google is the mother of creation. It has been proved once again here, Google files a patent for new Needle free blood draw system that can be used either as a wearable on a person’s wrist or as a hand-held device that takes blood from a fingertip or other parts of the body.

The below image shows the working process of the Google’s New Needle free blood draw system.

Abstract by Google

“A system for needle-free drawing of blood is disclosed. A device can include an evacuated negative-pressure barrel with a membrane sealing an aperture at a distal end, and a housing affixed to a proximal end. An accelerator barrel can be positioned within the negative-pressure barrel and fixed to the housing, with an open proximal end in a chamber in the housing, and an open distal end aligned with the aperture. The chamber can be filled with pressurized gas, and a trigger valve can hydrostatically separate the chamber from the open proximal end of the accelerator barrel. A micro-particle positioned within the accelerator barrel can be accelerated to high speed by an abrupt surge of gas by releasing the trigger valve. The micro-particle can attain enough momentum to pierce the aperture membrane and penetrate adjacent dermal tissue. A resulting micro-emergence of blood can be drawn into the negative pressure barrel.”
