AIIMS Raipur nurse develops patented respiratory device to curb airborne infections
The Indian Patent Office in New Delhi granted a utility patent for the device.
The HOAC Combo is a closed-system respiratory support unit designed to reduce the risk of airborne infections during nebulisation, sputum sampling, incentive spirometry, and low-flow oxygen therapy. It offers protection to both patients and healthcare workers.
The HOAC device is currently in the functional prototype development phase, with efforts underway to secure funding.
This will be followed by pilot studies and clinical validation, paving the way for its large-scale implementation in India and globally.
Arokiaraj U showcased this device at the India Innovation Summit 2025, held on March 18–19 at Bharat Mandapam Convention Centre, New Delhi. The Department of Health Research (DHR) and the Indian Council of Medical Research (ICMR) organised the summit.
The device has also been published on the ATLAS of Innovation platform, a research platform supporting the development of new technologies for TB elimination.
Lt. Gen. Ashok Jindal (Retd), Executive Director and CEO of AIIMS Raipur, congratulated Arokiaraj, calling the development a significant achievement for AIIMS Raipur. AIIMS Raipur nominated Arokiaraj for the National Florence Nightingale Award and the National Science Award 2025 in recognition of his contribution.
Arokiaraj expressed gratitude to the Medical Superintendent, the CTVS department, and the AIIMS administration for their support and guidance.

One of rarest neuro cases treated at AIIMS-R
Raipur: A 38-year-old woman suffering from spontaneous intracranial hypotension (SIH) for over two months made a complete recovery following a rare endovascular procedure at the All India Institute of Medical Sciences (AIIMS) in Raipur. The condition, caused by a cerebrospinal fluid (CSF) leak, severely impacted her quality of life, leaving her unable to perform routine activities. A multidisciplinary team from the departments of neurosurgery, neurology, and radiology at AIIMS Raipur evaluated the patient. Dr Richa Singh Chauhan, a neuroradiologist, identified the underlying cause as SIH. She pinpointed a rare CSF-venous fistula (CSF-VF) at the right L1 vertebra using advanced neuroimaging and a lateral decubitus Digital Subtraction Myelography (DSM). In this condition, CSF abnormally drains into the venous system. The treatment was performed by a team of interventional neuroradiologists led by Dr Nihar Vijay Kathrani. They used a minimally invasive interventional radiology technique via the right femoral venous access to successfully seal the fistula. The patient experienced a complete resolution of her symptoms after the procedure. A follow-up MRI confirmed the normalisation of her intracranial pressure. The anaesthesia team was led by Prof. Dr Subrat Singha, head of the Department of Anaesthesiology, along with Dr Vankdavath Lavanya, Dr Ananya Rao, and Dr Hashil. Prof. Dr N.K. Bodhey, head of the Department of Radiodiagnosis, said CSF-venous fistula is an extremely rare and recently recognised cause of SIH. He added that fewer than five such cases have been diagnosed and treated in India. This is the first case to be both diagnosed and treated at an AIIMS or Institute of National Importance (INI) in India. Lt Gen (retd) Ashok Jindal, executive director and CEO of AIIMS Raipur, congratulated the team. He said the case reflects the institution's multidisciplinary strength and its advanced diagnostic and interventional capabilities. The case sets a new standard in managing rare neurological disorders in India. Get the latest lifestyle updates on Times of India, along with Friendship Day wishes , messages and quotes !

AIIMS Raipur, IIT Indore hold health tech masterclass; focus on AI, future innovations
AIIMS Raipur, in collaboration with IIT Indore's DRISHTI CPS Foundation, recently hosted a masterclass focusing on integrating technology and AI into healthcare RAIPUR: The All India Institute of Medical Sciences (AIIMS) Raipur hosted a masterclass on Technology Interventions in Healthcare, in collaboration with the DRISHTI CPS Foundation, an initiative by IIT Indore. The event focused on how technology and artificial intelligence (AI) can be integrated into healthcare services. A team from the Foundation visited AIIMS Raipur and toured key clinical areas, including the Radiology Department, laboratories, and the Trauma and Emergency Department. This visit gave insight into the current clinical workflows and operational challenges, which will help in developing AI-based tools for hospital settings. A discussion followed on how the National Mission on Interdisciplinary Cyber-Physical Systems (NM-ICPS) can be integrated into services at AIIMS Raipur. The highlight of the visit was the Charak Masterclass – a full-day knowledge-sharing session that brought together faculty, innovators, researchers, and clinicians. Lieutenant General Ashok Jindal (Retired), Executive Director and CEO of AIIMS Raipur, said the collaboration would benefit students, residents, and faculty. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like New Launch at Godrej Sector 12 | Luxurious 3 BHK + S & 4 BHK Homes @₹2.90 Cr* Godrej Majesty Learn More Undo He added that it would also help in setting up a Digital Health Innovation Centre at AIIMS Raipur to develop and scale healthcare innovations. Professor (Dr) Abhiruchi Galhotra, Dean (Research), said the partnership would encourage faculty and residents to take part in advanced research that combines healthcare and digital technology to improve services. The masterclass featured talks on emerging topics such as the evolution of healthcare through data and AI, neural networks and AI applications, and using AI and machine learning to reduce ventilator alarm fatigue in critical care. Experts also gave live demonstrations on 3D modelling from radiology images, digital prescriptions using optical character recognition and voice-to-text tools, clinical decision support systems, and the use of augmented and virtual reality in healthcare. Faculty from various departments presented their AI-based projects and sought technical and financial support from IIT Indore. Scientists from the DRISHTI Foundation acknowledged these proposals and agreed to take them forward. The event concluded with the SRIJAN Centre for Innovation and Incubation presenting a roadmap for future collaborations, pilot projects, and technology validation efforts. AIIMS Raipur has also submitted a proposal for a 'Silicon Hub' under the Department of Science and Technology, in partnership with the DRISHTI Foundation. Professor (Dr) Eli Mohapatra, Dean Academics; Dr Krashnadutt Chavali, Dean Student Welfare; Professor (Dr) Ekta Khandelwal, Associate Dean Research; and other faculty members and researchers attended the event.
