Inventors include A. Lakshmi Narayana; Dr. M. Abdullah; Rithika Srinivasan; and Dr Ramya Mohan.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: One of the most critical challenges in modern maternal healthcare is the early detection of fetal abnormalities and pregnancy-related complications, especially in rural and resource-limited settings where access to advanced diagnostic facilities is limited. Conventional prenatal screening methods often require expensive laboratory tests, specialized equipment, and trained personnel, making them less accessible, time-consuming, and sometimes invasive. The main objective of this invention is to provide a point-of-care diagnostic tool for non-invasive prenatal screening using maternal biomarkers that is portable, affordable, and easy to operate. The proposed portable prenatal screening system utilizes a biosensing module designed to analyze maternal biomarkers from non-invasive samples such as saliva or minimal blood input, enabling early detection of potential fetal risks and maternal health conditions. An embedded microcontroller unit serves as the core processor, responsible for acquiring sensor data, executing biomarker analysis algorithms, and delivering accurate screening results in real time. The device integrates a userfriendly LCD display for immediate visualization of screening outcomes and risk indicators without the need for complex external systems. Additionally, the system includes a compact sample collection interface, a rechargeable power source for field usability, and visual alert mechanisms to indicate normal, moderate, or high-risk conditions. The ergonomic and portable design ensures reliable usage in homes, primary healthcare centers, rural outreach programs, and point-of-care environments, thereby improving accessibility to early prenatal screening and supporting timely medical intervention.
