Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a modular polysomnography device and method. Background Art

[0002] A polysomnogram is a medical device used to monitor and analyze sleep-related physiological parameters, and plays an important role in the field of sleep medicine. A polysomnogram mainly collects and records a variety of physiological signals during sleep by sticking multiple electrodes and sensors on the surface of the human body. These physiological signals include electroencephalogram (EEG), electrooculogram (EOG), electromyogram (EMG), electrocardiogram (ECG), respiratory airflow, respiratory movement, blood oxygen saturation, etc. Through comprehensive analysis of these physiological signals, doctors can accurately judge the sleep stage, sleep quality, whether there are sleep breathing disorders and other problems.

[0003] Current polysomnography monitors are usually composed of electrodes and sensors, signal amplifiers and data acquisition systems. Electrodes and sensors are the front-end acquisition devices of polysomnography monitors. Electrodes are used to collect bioelectric signals such as EEG, EOG, EMG, and ECG, while sensors are used to monitor physiological parameters such as respiratory airflow, respiratory movement, and blood oxygen saturation. Since the physiological signals collected from the human body are very weak, they need to be amplified to a processable level through a signal amplifier for subsequent analysis and processing. The data acquisition system is responsible for converting the amplified physiological signals into digital signals and recording and storing them in real time.

[0004] However, since polysomnography requires the use of multiple sensors and instruments, multiple electrodes and sensors need to be attached to the patient's body and connected to numerous lead wires, which may cause discomfort such as itching and pain on the skin. The restraint of the lead wires may also restrict movements such as turning over during sleep. Therefore, we need to propose a modular polysomnography device and method to solve the above-mentioned problems, so that it can split the polysomnography equipment into multiple modules, transmit data wirelessly, and minimize the use of cables.
