MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641004983 A) filed by Dr. Manoj Prabu M; Mr. Dinesh Kumaran J; Ms. Esthar S; Ms. Jeya Monika P; and Mr. Shree Vishnu Kumar B, Coimbatore, Tamil Nadu, on Jan. 19, for 'design of a wearable oxygen concentrator for continuous respiratory support.'

Inventor(s) include Dr. Manoj Prabu M; Mr. Dinesh Kumaran J; Ms. Esthar S; Ms. Jeya Monika P; and Mr. Shree Vishnu Kumar B.

The application for the patent was published on March 13, under issue no. 11/2026.

According to the abstract released by the Intellectual Property India: "Chronic respiratory diseases such as Chronic Obstructive Pulmonary Disease (COPD), asthma, and other pulmonary disorders often require continuous oxygen therapy to maintain adequate blood oxygen levels. Conventional oxygen delivery systems, including oxygen cylinders and stationary concentrators, are bulky and restrict patient mobility. To address these limitations, this project presents the design and development of a wearable oxygen concentrator capable of providing continuous respiratory support in a compact and portable form. The proposed system operates by drawing ambient air through a dust air purifier, followed by compression using a positive compressor motor. Oxygen enrichment is achieved through a zeolite sieve bed employing Pressure Swing Adsorption (PSA) technology, which selectively removes nitrogen from compressed air. The concentrated oxygen is further conditioned using an HMV filter to regulate humidity and temperature, ensuring safe and comfortable delivery to the patient through a nasal pump. A small oxygen cylinder is incorporated as a backup source to ensure uninterrupted oxygen supply during power failure or system interruption. The wearable oxygen concentrator is designed to enhance patient comfort, mobility, and independence while delivering reliable oxygen therapy for long-term use. This system provides a cost-effective and efficient alternative to traditional oxygen delivery methods and is suitable for home-based and ambulatory respiratory care, thereby improving the quality of life for patients with chronic respiratory conditions."
