MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202611108208 A) filed by Noida Institute Of Engineering And Technology Pharmacy Institute on September 09, 2026, for Spring-Driven Autoinjector With Adaptive Impact-Attenuation For Multi-Volume Subcutaneous Drug Delivery.
Inventors include Dr. Rakhi Mishra; and Ms. Kavita Rana.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The invention presents an adaptive spring-driven autoinjector platform for subcutaneous drug delivery, designed to modulate plunger impact energy across varying fill volumes without device modification. A fill-volume-responsive driving rod assembly integrates two complementary mechanisms: a viscoelastic damping element at the distal end that absorbs kinetic energy proportionally to impact velocity, and a graduated friction collar with circumferential ribs that engage the textured housing interior over a length corresponding to rod flight distance. Together, these features maintain plunger impact energy within ±15% of nominal across fill volume reductions up to 50%. Validation across 0.5, 1.0, and 2.0 mL device variants confirmed dose accuracy within ISO 11608 standards, consistent penetration depth, absence of syringe failure, reduced subvisible particle generation, and preserved drug quality. This platform enables flexible dosing from a single device, ensuring safety, reliability, and product integrity across multiple therapeutic applications.
