Breath state detection device and detection method

Abstract

The invention discloses a breath state detection device and detection method. The detection device includes; a first acceleration sensor which attaches to a chest of a human body and is used for acquiring motion information of the chest; a second acceleration sensor which attaches to an abdomen of the human body and is used for acquiring motion information of the abdomen; a posture acquisition unit which is used for acquiring posture information of the human body; and a breath state extraction unit which is in a communication connection with the first acceleration sensor, the second acceleration sensor, the posture acquisition unit, and is used for extracting a chest breath signal from the motion information of the chest based on the posture information of the human body, extracting an abdomen breath signal from the motion information of the abdomen based on the posture information, and then acquiring the breath state of the human body. The two acceleration sensors attach to the chest and the abdomen of the human body, and then the breath state can be detected, the breath state detection device is comfortable in wearing, and the problem that a breath belt is uptight can be solved. The success rate of signal recognition can be increased on the basis of the posture information of the human body, and the accuracy of breath signal extraction can be improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a breathing state detection device and a detection method. Background technique [0002] In the existing sleep breathing detection applications, the breathing belt is usually used to tie the breathing belt to the human body to detect the breathing state of the human body, but because the breathing belt is relatively tight, the user feels tight during the breathing process On the one hand, it is uncomfortable to wear, and on the other hand, it will affect the accuracy of respiratory state detection. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a breathing state detection device and detection method, and solve the problem in the prior art that the breathing belt is tight, which causes uncomfortable wearing and affects the accuracy of breathing state detection. [0004] The technical scheme for realiz...
