Problems solved by technology

Although the sleep breathing detection technology based on PSG can accurately detect the abnormal phenomenon of breathing, because this detection method requires the patient to wear a mask, chest belt and more electrodes, it has a great physiological and psychological load on the patient, and is prone to " The "first night effect" affects the results of sleep monitoring; moreover, the operation of the instrument is complicated and the detection cost is expensive
At present, there are not many professional institutions for the diagnosis of breathing and sleep disorders, and patients need to queue for a long time to receive the examination; patients are in an unfamiliar environment, connected to multiple wires on their bodies, difficult to fall asleep or sleep lightly, and easy to wake up at night, which makes the experiment fail or the experiment result bias

Abstract

The invention belongs to the technical field of biological treatment monitoring, and particularly discloses a sleep breath state signal acquisition device based on the biological resistance and a monitoring system. The signal acquisition device comprises a signal acquisition unit, a processing control unit, a data storage unit and a wireless communication unit. The signal acquisition unit comprises two electrodes at least in contact with the chest of the human body, a chest resistance acquisition module connected with the electrodes, a heart rate acquisition module connected with the electrodes and a snore acquisition module. The monitoring system comprises the signal acquisition device and a terminal processing unit in wireless connection with the signal acquisition device. In this way, according to the signal acquisition device and the monitoring system, the sleep breath state is monitored by acquiring a chest resistance signal and a heart rate signal based on the biological resistance technology in cooperation with a snore audio signal, and meanwhile the problems that as wires are connected to the body of a patient, the patient can not fall asleep easily, or the sleeping depth is small, and the patient is prone to being wakened are solved through wireless signal transmission; the signal acquisition device and the monitoring system have the advantages of being simple, low in price, convenient to wear and suitable for families.

Description

technical field [0001] The invention belongs to the technical field of biomedical monitoring, and in particular relates to a bio-impedance-based sleep breathing state signal acquisition device and a monitoring system. Background technique [0002] Bioimpedance technology is a non-invasive detection technology that uses the electrical characteristics of biological tissues and organs to extract human physiological and pathological information. Different human tissues and organs have unique bioimpedance characteristics, and changes in the state or function of tissues and organs will also be accompanied by corresponding changes in bioimpedance characteristics. For example, in the prior art, the degree of fatigue of the diaphragm is divided into different types based on the principle that the degree of fatigue of the diaphragm is related to the degree of synchronization between the peaks of the chest respiratory electrical impedance signal and the peak of the abdominal respirator...
