MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202641091314 A) filed by Dayananda Sagar College Of Dental Sciences on July 27, 2026, for Intelligent Dental Anesthesia Delivery Device With Real-Time Nerve Localization And Pain Response Feedback.
Inventors include Dr. Vinod Rangan; Dr. Nayana M; Dr. Ramnarayan B K; Dr. Ashwin Prabhu; Dr. Shobha E S; Dr. Sangeetha Ramu; Dr. Pradeep Chandra K; Dr. Koduru Sravani; and Dr. Sandhya Khasnis.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention an intelligent dental anesthesia delivery device is disclosed for controlled administration of a dental anesthetic using real-time nerve localization and pain-response feedback. The device comprises a handheld delivery unit, a replaceable anesthetic cartridge, a motor-driven metering pump, a needle assembly, a multimodal nerve-localization module, physiological response sensors, and a controller. The localization module combines ultrasound, tissue-impedance, and needle-tip pressure data to generate a continuously updated nerve-proximity map. The physiological response sensors acquire one or more of pulse rate, skin conductance, facial muscle activity, and patient-operated discomfort input. The controller regulates injection flow, pressure, and delivered volume within clinician-defined limits and pauses delivery when unsafe pressure, possible vascular entry, excessive patient response, or low localization confidence is detected. A clinician interface displays needle position, nerve proximity, injection parameters, cumulative dose, and alerts. The device improves targeting accuracy, reduces painful high-pressure injection, supports patient-specific delivery, and retains clinician authority over anesthetic administration.
