IIT-B researchers develop a needle-less syringe

Mumbai: A team of researchers at IIT Bombay led by Professor Viren Menezes, Department of Aerospace Engineering, has developed an unprecedented needle-less shock syringe. The invention aims to reduce needle-related fear and anxiety, using high-energy shock waves to deliver the drug. Unlike traditional needles, this shock syringe uses a liquid microjet that penetrates the skin, making the injection painless. This reduces the patient’s anxiety and consequently speeds up the healing process. The technology draws inspiration from aerospace engineering principles, particularly the dynamics of shock waves.

The syringe works by releasing pressurized nitrogen gas through a micro-shock tube. Shock waves generated during fluid flight propel the drug at speeds faster than a commercial airplane. The device was tested on rats in the laboratory and proved to be as effective or better than traditional needles. In particular, it proved effective against sticky drugs such as terbinafine, and insulin derived from it was found to be long-lasting in diabetic rats.

The lead researcher of the project said that through this technology, shockwaves have been used as a creative tool in the health system. The patient does not feel afraid with this needle-free injection. This reduces the risk of injury. Importantly, injections with a needle can cause infection, while injections without a needle do not. Moreover, since each nozzle can be used a thousand times, the cost of this syringe also reduces. Therefore it can be used for mass vaccination.

Now the process of patent and regulatory approval is going on for this syringe. The shock syringe could revolutionize the way medicine is given. This could prove to be a safer and more convenient option for millions of people around the world.
