Injections can not be afraid — created "smart" needle for precise injections
Source:
Medical technology is evolving much faster than cars and other equipment. The emergence of "smart" needles for syringes was only a matter of time and they finally created. Their development involved researchers from Women's hospital Brigham — they did so the needle was pressure-sensitive fabrics. This allows you to make more accurate and painless injection in such vulnerable areas as the eyes and subcutaneous tissue between the skin and muscles.
The Prototype was called "intelligent injector to target a tissue," or simply i2T2. Its main part is a sensor to detect changes in applied pressure when the tip passes through different types of biological tissues of different densities. For example, the needle can quickly determine which layer of the eye it is. It is expected that this will greatly facilitate the work of doctors, because any error in the administration of injections can cause serious problems.
Typically, difficulties arise when injecting medication into the space between the layers of the sclera and choroid in the back of the eye. The needle has to pierce a layer of the sclera with a thickness of only 1 millimeter and immediately stop, taking care not to damage choroid behind the retina. The sensor built into the prototype I2T2 helps to do it without any problems.
The Needle can penetrate in other places that require extreme accuracy. In laboratory tests on animals I2T2 has proved its effectiveness in the implementation of injection in the epidural space adjacent to the spinal cord, and subcutaneous tissue between the skin and muscles. He also successfully delivered stem cells into the eye that is often used in regenerative therapy.
