Description:FIELD OF THE INVENTION
Our Invention is a RADAR-BASED NON-CONTACT VITAL SIGNS MONITORING SYSTEM

BACKGROUND OF THE INVENTION

In today's healthcare environment where infection control, patient comfort, and operational efficiency are paramount, traditional contact-based monitoring systems present significant limitations.

To address these challenges, Criterion Tech Pvt. Ltd., has developed an innovative Radar-Based Vital Signs Monitoring System utilizing cutting-edge millimeter wave radar technology that enables completely contactless detection of patient vital signs.

PRIOR ART SEARCH

WO2025055235A1: A non-contact vital sign data monitoring method and system based on a millimeter-wave radar, and a computer-readable storage medium. The method comprises: receiving echo signals in a radar detection space, and on the basis of the echo signals, selecting static detected persons from the radar detection space to serve as target objects (S10, S110); on the basis of echo signals of the target objects, calculating spatial position information of the target objects in the radar detection space (S20, S120); on the basis of the spatial position information, determining the number of target objects equidistant from the radar (S30, S130); if there are at least two target objects equidistant from the radar in the radar detection space, calculating phase information on the basis of azimuth angle information and elevation angle information of the target objects (S40, S150); and calculating vital sign data of the target objects on the basis of the phase information (S50, S160).

WO2023016948A1: A radar system (10) for vital signs monitoring such as at least heart rate or breathing and a method for mitigating random body movement and external interference effects in vital signs monitoring such as at least heart rate or breathing by employing a radar system (10) that is configured for providing in-phase and quadrature signals from reflected and received radar waves are provided. The problem of random body movement effects and external interference affecting vital signs monitoring is at least mitigated by decomposing and filtering a reconstructed displacement signal x(t) using a time and frequency analysis technique such as Short-Time Fourier Transform (STFT), followed by a Non-negative Matrix Factorization (NMF) operation. This decomposition allows the identification of time and frequency basis components containing the random body movement interference. Hence, the filtered signal can be reconstructed after removing the random body movement components, thus enabling reliable and robust vital-signs parameter estimation.

SUMMARY OF THE INVENTION
● This Radar-Based Monitoring System combines advanced radar signal processing with real-time data analysis to capture vital signs through the detection of minute chest movements caused by cardiac activity and respiratory functions. The system operates without any physical contact with the patient, eliminating discomfort and reducing infection transmission risks while maintaining clinical-grade accuracy. Being wireless, the system has minimal regulatory compliance requirements, making it easier to deploy across various healthcare settings.

● The system is compact, lightweight, and features an intuitive touch-screen interface that provides real-time visualization of detected vital signs. The millimeter wave radar technology penetrates clothing and bedding while being completely safe for continuous human exposure, making it suitable for 24/7 patient monitoring applications. Its contactless nature makes it perfect for home monitoring scenarios where patients can be monitored continuously without any physical sensors or discomfort.

● In clinical environments, this revolutionary system provides automatic monitoring of two critical vital signs - heart rate and respiratory rate - without requiring any intervention from healthcare staff. Nurses and doctors can obtain accurate vital signs readings simply by positioning the device near the patient, eliminating the time-consuming process of applying sensors, cuffs, or electrodes. This automation significantly reduces workload on clinical staff while ensuring continuous, uninterrupted monitoring.

● For home healthcare applications, the system enables family members and patients to monitor vital signs independently without medical training or complex setup procedures. The wireless, contactless operation means patients can go about their daily activities while being continuously monitored, making it ideal for elderly care, chronic disease management, and post-operative recovery monitoring at home.

This Radar-Based Monitoring System provides accurate, contactless detection of:
● Heart Rate - Through detection of micro-movements caused by cardiac contractions
● Respiratory Rate - Via monitoring of chest wall movements during breathing cycles
● Breathing Patterns - Including detection of irregular breathing or apnea events
