Intellectual Property India Publishes Patent Application for 'An Artificial Intelligence Based Multi-Channel Auscultation Device For Differential Diagnosis Of Asthma-Copd' Filed by National Institute Of Technology Raipur; Department Of Health Research; and All India Institute Of Medical Sciences Raipur

MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202521084715 A) filed by National Institute Of Technology Raipur; Department Of Health Research; and All India Institute Of Medical Sciences Raipur, Raipur, Chhattisgarh, on Sept. 6, 2025, for 'an artificial intelligence based multi-channel auscultation device for differential diagnosis of asthma-copd.'

Inventor(s) include Vaibhav Koshta; Dr. Bikesh Kumar Singh; Dr. Ajoy Kumar Behera; and Dr. Ranganath T. Ganga.

The application for the patent was published on Dec. 12, under issue no. 50/2025.

According to the abstract released by the Intellectual Property India: "An artificial intelligence-based multi-channel auscultation device (100) is disclosed for differential diagnosis of asthma and chronic obstructive pulmonary disease (COPD). The device comprises a wearable auscultation pad (1) with four microphones (2) connected to stethoscope heads (5) via microphone cases (3) and hollow tubes (4). The microphones (2) are powered through a phantom power supply (7) in a preamplifier (6) with a sound card (8), and the filtered signals are transmitted via USB interface (10) to a processing unit (13). The processing unit segments the lung sounds and extracts statistical features (15a-15e) using a feature extraction module (14). A diagnostic engine (16) uses classifiers including SVM (17a), kNN (17b), DT (17c), RF (17d), and XGB (17e), trained on a self-collected dataset (18), and generates outputs (19) which are aggregated using a voting classifier (20) to identify asthma or COPD accurately and in real-time."
