Non-contact heartbeat and breathing disorder monitoring system and method

Abstract

The invention relates to a non-contact heartbeat and breathing disorder monitoring system and a monitoring method. The system and the method are applied to dynamic health monitoring, and are especially suitable for personal daily home monitoring of patients with respiratory and cardiac diseases. The system and the method comprise the following operations: emitting and receiving radar signals via aradar signal module, monitoring the received radar signals in real time and recording breathing and/or heartbeat status information of a monitored object; modulating and amplifying the received radarsignals via an information processing module; conducting data analysis and judgement on the processed signals via a data analysis module; and transmitting processed and analyzed data to a server viaa communication module. With the application of the product (the system and the method), physiological data of human breathing and heartbeat can be periodically and continuously monitored and acquiredin a hidden mode for a long time, and physiological and psychological discomforts caused by wearable equipment can be avoided.

Description

technical field [0001] The invention relates to a non-contact heartbeat and breathing disorder monitoring system, which is applied to dynamic health monitoring, and is especially suitable for daily home monitoring of patients with breathing and heart diseases. Background technique [0002] Sleep-disordered breathing can be roughly divided into: obstructive sleep apnea hypopnea syndrome, central sleep apnea syndrome, Chen-Yishi's breathing and sleep hypopnea syndrome. Among them, obstructive sleep apnea syndrome (OSA) is the most common sleep-disordered breathing, with an incidence of more than 4% to 5% in adults, and is an independent risk factor for a variety of systemic diseases. Obstructive sleep apnea syndrome is characterized by repeated upper airway collapse and disappearance of airflow during sleep, but breathing movement still exists. It was defined as "interstitial airflow cessation > 10 s" and "sleep apnea-hypopnea index (Al-Il) > 5 times / h". During sleep, ...

AI Technical Summary

Problems solved by technology

[0004] 1. In the initial screening stage of suspected cases, patients are required to wear a variety of medical monitoring equipment after admission, which not only brings inconvenience to patients, but also occupies already tight hospital beds and wastes precious medical resources;

[0005] 2. Contact vital sign monitoring equipment will bring physical and psychological discomfort to the wearer, resulting in reduced patient compliance and affecting the accuracy of data collection to some extent;

[0006] 3. Due to the limitation of objective conditions, the patient’s stay in the hospital is relatively short (generally no more than 48 hours), so only short-term heartbeat and respiratory data can be obtained, and clinicians cannot fully understand the periodic changes of the patient’s condition;

[0007] 4. For patients who have been diagnosed with sleep-disordered breathing and need continuous treatment, there is still a lack of a simple and convenient indicator monitoring method, and patients need to be repeatedly admitted to the hospital for efficacy observation;

[0008] 5. From the initial screening of the disease to the continuous observation of treatment, it is impossible to provide clinicians with convenient, comprehensive and visualized data statistics and analysis functions
