Embodiment Construction

[0047] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] The present invention provides a method and system for acquiring respiratory information. When the human body breathes, the contraction and relaxation of the lungs are mainly achieved by the coordinated movement of multiple muscles around the lungs, especially the muscle groups on both sides of the spine (such as the intercostal muscle, upper serratus posterior, lower serratus posterior), back muscle group, abdominal muscle group and chest muscle group, etc., and the movement of muscles will cause changes in body surface pressure, which can be compared with the human body after processing and analysis Respiratory information related. Based on the above ideas,...

Abstract

The invention discloses a method and a system for acquiring respiratory information. The method comprises the following steps of: collecting the pressure signals corresponding to different body partsof the target human body according to the preset pressure collection mode; performing signal processing on the collected pressure signal, and analyzing the respiratory signal corresponding to the target human body; obtaining a respiratory intensity and a respiratory frequency corresponding to the target human body according to the obtained respiratory signal; the method is provided with the beneficial effect of obtaining more accurate respiratory information by collecting multiple body surface pressure signals, which improves the accuracy and reliability of respiratory information acquisition,and further make the acquisition of respiratory information reproducible. In addition, the method uses multiple points to simultaneously collect surface pressure information of the body surface whenthe target human body breathes. With the technical solution of human anatomy for correlation analysis, individualized breathing information such as respiratory pattern and organ muscle participation of the target human body can be further obtained.

Description

technical field [0001] The invention relates to the field of biomedical technology, in particular to a method and system for acquiring respiratory information. Background technique [0002] Respiration is an important physiological process of the human body, and respiratory parameters are an important physiological parameter in clinical monitoring; for example, when a patient suffers from asphyxia or even dies, the asphyxia alarm of the monitoring device can promptly remind the medical staff to pay attention to the patient's condition and avoid delaying the patient's recovery. In addition, the precise implementation of medical imaging and radiotherapy often requires the use of patient respiratory information, such as four-dimensional CT imaging technology (4D-CT) corresponding to breathing time, respiratory gated radiotherapy technology (Respiratory-Gated Radiotherapy) ), etc. Accurate acquisition of patient respiratory information (such as respiratory phase, respiratory cyc...
