MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641025945 A) filed by Rajalakshmi Engineering College, Chennai, Tamil Nadu, on March 5, for 'portable cardiac early-warning assist device for rural health screening with integrated risk classification and automated referral routing.'
Inventor(s) include Dr. M. Thangamani; and Mr. Vinish Alikkal.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "We present an automated cardiac triage system compnsmg portable ECG acquisition (I -3 leads, 250-500 Hz sampling), pulse oximetry, and non-invasive vital sign measurement integrated with an on-device machine learning classifier. The system stratifies patients into risk categories (low: 0.3, moderate: 0.3-0.6, high: 0.6) by analyzing ECG morphological features (ST clcvntion/dcprcssion, QRS duration, T-wave hauges, arrhytlunias), vital sign abnormalities (SpO,, blood pressure, heart rate extremes), and symptom severity (chest pain, dyspnea, diaphoresis). High-risk patients trigger automated referral generJtion with patient data, ECG wavcfum1s, and location coordinates transmitted to the nearest equipped cardiac facility. Nonspecialist health workers (ASI-IA, ANM, health center staff) achieve specialist-equivalent triage within 2-3 minutes. Bane*y-powered offline operation eliminates dependence on mains power and internet connectivity. The approach reduces time-to-definitive-cardiac-care by 30-60 minutes while rcduing false-positive refenals by 25-40%, improving acute coronary syndrome outcomes and enabling equitable cardiac care access in resource-limited regions."
