Embodiment

[0058] This embodiment provides a tension variable abdominal belt, such as image 3 As shown, it includes an abdominal belt main body 1 and an adjustment structure 2 . Wherein: the abdominal belt main body 1 has a certain axial length and can be bound on the human body in a circumferential direction, and the abdominal belt main body 1 has a certain transverse width (the width is at least 5 cm); the adjustment structure 2 is connected in series to the abdominal belt Take body 1 on.

[0059] When the inner surface of the abdominal belt main body 1 is supported by the external support force, the adjustment structure 2 adjusts the length of the abdominal belt main body 1 to become longer; the external support force received by the inner surface of the abdominal belt main body 1 becomes smaller or When disappearing, the adjustment structure 2 adjusts the length of the abdominal belt main body 1 to become shorter; in the process of the adjustment structure 2 adjusting the length of...

Abstract

The present invention provides a tension-variable abdominal belt. The tension-variable abdominal belt comprises: an abdominal belt body, which has a certain axial length, is capable of being bound toa human body in the circumferential direction, and has a certain lateral width; and an adjusting structure, which is connected to the abdominal belt body in series; when the inner side surface of theabdominal belt body is externally supported by external supporting force, the adjusting structure adjusts the length of the abdominal belt body to increase the length of the abdominal belt body; whenthe external supporting force on the inner side surface of the abdominal belt body is reduced or disappears, the adjusting structure adjusts the length of the abdominal belt body to decrease the length of the abdominal belt body; in the process that the adjusting structure adjusts the length of the abdominal belt body to be gradually increased, the needed external supporting force is large at thebeginning, and the needed subsequent external supporting force is small. According to the tension-variable abdominal belt, when the diaphragm contracts, the diaphragm can be prevented from descendingtoo fast, so that the upper airway is prevented from being closed and sunken, and the problem of inspiration pause is solved.

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 suffering from obstructive sleep apnea hypopnea syndrome, whose typical symptoms are apnea and hypoventilation during sleep, frequent drops in blood oxygen saturation, and daytime sleepiness. Obstructive apnea refers to the absence of airflow through the mouth and nose during apnea, but the presence of thoracic and abdominal breathing movements. [0003] The inventors found in clinical work that in OSAHS patients without surgical indications, the position of the diaphragm is an important indicator closely related to the apnea-hypopnea index. The applicant believes that the excessive inspiratory pressure at the beginning of inspiration caused by the high position of the diaphragm is an independent pathogenic factor of upper airway occlusion in patients with OSAHS. Ex...
