A tension variable abdominal belt

Abstract

The invention provides a tension-variable abdominal belt, comprising: a main body of the abdominal belt, which has a certain axial length, can be bound on a human body in a circumferential direction, and has a certain lateral width; an adjustment structure, which is connected to the main body of the abdominal belt in series; When the inner side of the belt body is supported by the external support force, the adjustment structure adjusts the length of the belly belt body to become longer; when the external support force on the inner side of the belly belt body decreases or disappears, the adjustment structure adjusts the length of the belly belt body to shorten. In the process that the length of the main body of the abdominal belt is gradually increased by the adjusting structure, the external supporting force required at the beginning is large, and the external supporting force required in the subsequent period is small. The variable tension abdominal belt of the present invention can prevent the diaphragm from descending too quickly when the diaphragm is contracted, thereby avoiding the occurrence of upper airway closure, thereby solving the problem of inhalation pause.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an abdominal belt with variable tension. Background technique [0002] OSAHS patients refer to patients with obstructive sleep apnea-hypopnea syndrome, whose typical symptoms are apnea and hypoventilation during sleep, frequent drop in blood oxygen saturation, and daytime sleepiness. Obstructive apnea refers to the absence of airflow through the nose and mouth during apnea, but the presence of chest and abdominal breathing movements. [0003] The inventors found in clinical work that the position of the diaphragm is an important indicator closely related to the apnea-hypopnea index in OSAHS patients without surgical indications. The applicant believes that the excessive inspiratory pressure at the initial stage of inspiration caused by the high position of the diaphragm is an independent pathogenic factor of upper airway collapse in patients with OSAHS. Excessive insp...

Problems solved by technology

[0004] The principle of the above point of view is that when the same diaphragm contraction force drives the diaphragm down, the resultant force of the driving force on the diaphragm at an excessively high position is greater, which in turn causes the diaphragm to descend faster, causing a large inspiratory load to be generated too quickly inside the thoracic cavity. pressure, causing airway closure during the inspiratory phase, leading to inspiratory pauses
