Embodiment 1
[0040] Such as figure 1 As shown, a method for monitoring heart rate and respiratory rate provided in this embodiment includes the following steps:
[0041] S1. Collect the swing signal of the elastic part caused by heartbeat and breathing when the human body is lying on the elastic part;
[0042] S2, converting the collected swing signal into an angular velocity signal;
[0043] S3, converting the angular velocity signal into a frequency domain signal;
[0044] S4. Obtain the frequency value corresponding to the maximum value of the frequency domain signal within the preset respiratory frequency range, that is, the respiratory rate; obtain the frequency value corresponding to the maximum value of the frequency domain signal within the preset heart rate range, that is, the heart rate.
[0045] Preferably, in order to further improve the accuracy of heart rate and respiratory rate monitoring, this embodiment further includes the following steps after step S2:
[0046] Perfor...
Embodiment 2
[0055] Such as Figure 6-10 As shown, this embodiment also provides a carpet 1 , which includes a main body of the carpet 1 , and a monitoring device is arranged in the main body of the carpet 1 .
[0056] Monitoring devices, including:
[0057] The elastic part is used to convert the longitudinal impact force generated by the beating of the heart and respiration into a swing signal when the human body is lying down.
[0058] The angular velocity detection module is arranged on the elastic component and is used to convert the swing signal into an angular velocity signal;
[0059] The data processing module is connected with the angular velocity sensor, and is used to receive the angular velocity signal and output the heart rate and respiration rate.
[0060] Wherein, the elastic component is preferably a flexible circuit board 13, the speed detection module is preferably an angular velocity sensor such as a gyroscope 3, and the data processing module is a controller 4, such ...

Abstract
The invention relates to the technical field of sleep monitoring, in particular to a heart rate and respiratory rate monitoring method and monitoring device thereof, a blanket and a mattress. The method comprises the steps: collecting a swing signal, caused by heartbeat and respiration, of an elastic part on the condition of lying on the elastic part by a human body; converting the acquired swingsignal into an angular velocity signal; converting the angular velocity signal into a frequency domain signal; acquiring a frequency value corresponding to a maximum value of the frequency domain signal in a preset respiratory rate range, namely the respiratory rate; and acquiring a frequency value corresponding to the maximum value of the frequency domain signal in a preset heart rate range, namely the heart rate. According to the invention, when a person lies down, a longitudinal impact is generated on the human body at the moment of cardiac impulse according to the heart BCG principle; thelying position swings up and down due to the change of the gravity center; the cardiac beat signal is converted into the angular velocity signal by collecting the swing signal and the angular velocitysignal is converted into the heart rate signal, so that the monitoring of the heart rate and the respiratory rate is completed.
Description
technical field [0001] The invention relates to the technical field of sleep monitoring, in particular to a heart rate and breathing frequency monitoring method and device, a blanket and a mattress. Background technique [0002] Cardiac arrest refers to the sudden termination of cardiac ejection function, the disappearance of aortic pulse and heart sound, and severe ischemia and hypoxia of vital organs (such as the brain), leading to the end of life. Sudden cardiac arrest is more common in heart and lung organic diseases such as coronary heart disease, cardiomyopathy, and pulmonary embolism, especially during nighttime sleep. In addition, sleep apnea syndrome also widely exists in snoring people, which can lead to sudden respiratory arrest due to airway obstruction, and then cause life-threatening. Therefore, it is necessary to monitor sleep heart rate and respiration in the elderly or newborns with coronary heart disease, cardiomyopathy or potential risks. [0003] Most o...
