Problems solved by technology

However, PSG is expensive and the operating cost is high; there are not many professional institutions for the diagnosis of respiratory and sleep disorders at present, 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, it is difficult to fall asleep or sleep lightly, and at night Easy to wake up, which makes the experiment fail or the experimental results are biased

Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a bioimpedance-based wearable sleep breathing state monitoring system, including a monitoring belt 10 for collecting chest impedance and heart rate signals in a sleep state and a wireless monitor with the monitoring belt 10. The connected mobile terminal 20; the mobile terminal 20 includes a data processing unit 21 for performing data analysis and processing on the collected signals and a curve for displaying the relationship between chest impedance and heart rate after the data processing unit 21 analyzes and processes and A display unit 22 for data analysis results; the monitoring belt 10 includes a signal collection box 11 and a fixing belt 12 connected to the signal collection box 11 . In the embodiment of the present invention, the connection mode between the signal collection box 11 and the fixing belt 12 is a buckle connection (not shown in the figure), in addition, Velcro ...

Embodiment 2

[0041] continue as Figure 5 As shown, the biggest difference between the embodiment of the present invention and the first embodiment above is that the electrode array 111 is composed of four electrodes in contact with the chest of the human body, one pair of electrodes is signal excitation electrodes, and the other pair of electrodes is signal excitation electrodes. Collect electrodes. In the embodiment of the present invention, the electrode array 111 is distributed symmetrically about the center, wherein each electrode has the same size and the distance between adjacent electrodes is equal. For example, the four electrodes are arranged in a square shape on the surface of the signal collection box 11 that fits the human body. The other structures are the same as those in the first embodiment above, and will not be repeated here.

[0042] In the above two embodiments, by fixing the electrode array in the signal collection box, not only can the bio-impedance measurement be ...

Abstract

The invention belongs to the technical field of biomedical monitoring, and particularly discloses a bio-impedance-based wearable sleep respiration state monitoring system. The monitoring system comprises a monitoring tape and a mobile terminal, wherein the monitoring tape is used for collecting thorax impedance and heart beat rate signals in a sleep state; the mobile terminal is in wireless connection with the monitoring tape, and comprises a data processing unit and a display unit; the data processing unit is used for carrying out data analysis treatment on the collected signal; the display unit is used for displaying a data curve between thorax impedance and heart beat rate and the analysis result, which are analyzed and processed by the data processing unit; the monitoring tape comprises a signal collection box and a fixing strip; and the fixing strip is connected with the signal collection box. Therefore, the system disclosed by the invention is simple, cheap, convenient to wear, and suitable for families, and does not affect sleeping; and the test environment is a daily real sleep environment, so that the real daily sleep respiration state of a patient is monitored in real time under the condition without effects of movements such as sleep posture change.

Description

technical field [0001] The invention belongs to the technical field of biological medical monitoring, in particular to a wearable sleep breathing state monitoring system based on biological impedance. Background technique [0002] Bioimpedance technology is a non-invasive monitoring technology that uses the electrical characteristics of biological tissues and organs to extract human physiological and pathological information. Human tissues and organs have unique electrical properties, and changes in the state or function of tissues and organs will also be accompanied by corresponding changes in electrical properties. 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 respiratory electrical impedance signal. Bio-impe...
