MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641021587 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Feb. 24, for 'bed sore prevention patch.'
Inventor(s) include Dr Anees Ahmed F M; Dr Uvatharshini A; and Dr. Deepak Nallaswamy Veeraiyan.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "A breathable, thin, and flexible bed sore prevention patch is disclosed, comprising integrated pressure and optical light sensors configured to continuously monitor localized skin conditions at high-risk anatomical areas. The patch includes a microperforated skin-friendly adhesive layer that allows airflow and moisture exchange, minimizing irritation during prolonged wear. The emberlrled pressure sensor detects excessive or sustained mechanical load on the tissue, while the optical light sensor monitors skin status such as perfusion or micro-vascular changes indicative of ulcer risk. A low-power Bluetooth module wirelessly communicates real-time data and alert signals to a paired sma1tphonc or caregiver monitoring device, en ~hling timely repositioning or intervention to prevent pressure-induced injuries. The device is lightweight, comfortable, and capable of continuous operation, thereby enhancing patient safety and supporting early detection and prevention of pressure ulcers in both hospital and home-care environments. This invention is particularly beneficial for bedridden patients, post-operative individuals, elderly persons, and patients with limited mobility in hospitals, nursing homes, and home-care environments. By enabling early detection and continuous monitoring, the device helps prevent the development of pressure ulcers, improves patient comfort, and reduces healthcare burden through care management. Bed sores can progress through multiple stages from mild redness and inflammation to deep tissue necrosis and infection. Advanc.ed pressure ulcers can lead to severe complications such as cellulitis, osteomyelitis, sepsis, and gangrene, which significantly increase hospital stays, treatment costs, and mortality risk. Apart from physical discomfort, pressure ulcers also cause psychological distress and reduce quality of life for patients and caregivers. Existing methods for bed sore prevention primarily focus on mechanical pressure redistribution and manual monitoring. Common preventive devices include Air and water mattresses or alternating pressure mattresses, Cushions, foam pads and frequent repositioning."
