Method and system for acquiring respiratory information

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...

Problems solved by technology

The main disadvantages of using this method to obtain patient respiratory information are: in the supine position, the abdominal muscles and fat of the human body move during breathing, the abdominal surface is not smooth, and the signal acquisition method based on the abdominal surface is not stable. At the same time, individual differences and measurement The position dependence problem seriously interferes with the accuracy, reliability and repeatability of respiratory information collection
