IIT-Bombay Team Develops Nose-Free Syringe for Painless Injections

• Researchers at the Indian Institute of Technology, Bombay have developed a needle-free “shock syringe” for painless injections.

• The shock syringe uses high-energy pressure waves (shock waves) to pierce the skin, compressing the surrounding medium.

• The device, developed in 2021, is slightly longer than a regular ballpoint pen and has a micro shock tube consisting of three sections: the driver, driven, and drug holder.

• The shock syringe is filled with liquid drugs to create a microjet of the drug, which travels at a speed nearly twice as fast as a commercial aeroplane at take-off.

• The process of delivering drugs using a shock syringe is rapid and gentle, with most patients not feeling a thing.

• The shock syringe is designed to deliver medication rapidly and ensure consistent and precise drug delivery.

• The development could make immunisation drives quicker and more efficient for both children and adults, and prevent blood-borne diseases caused by needle-stick injuries.
