Embodiment Construction

[0054] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0055] When the inventors of the present invention studied the prior art, they found that when determining the therapeutic pressure output by the positive pressure ventilation therapy machine in the prior art, the patient's changing sleep position was not considered. Usually, when the patient's position changes during sleep, The minimum pressure required to maintain a patient's upper airway will vary accordingl...

Abstract

The invention discloses a pressure adjustment method and system of a positive-pressure breathing therapy machine. The pressure adjustment method includes monitoring whether a patient's body posture changes or not; generating body posture change information if with changes; determining output pressure of the positive-pressure breathing therapy machine according to the body posture change information. By monitoring the body posture change information of the patient, therapy pressure output by the positive-pressure breathing therapy machine can be automatically adjusted in time according to changes of body posture of the patient. Accordingly, the optimal therapy pressure of the positive-pressure breathing therapy machine can be adjusted when the posture of the patient changes in sleeping, the problem of long time in therapy pressure adjustment of the positive-pressure breathing therapy machine in the prior art is thoroughly solved, compliance with therapy effect and therapy is greatly improved, and use experience of the patient is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pressure adjustment method of a positive pressure ventilation treatment machine, and also relates to a pressure adjustment system of a positive pressure ventilation treatment machine. Background technique [0002] Sleep apnea-hypopnea syndrome refers to recurrent episodes of apnea more than 30 times per night during sleep or sleep apnea-hypopnea index (AHI, Apnea Hypopnea Index) ≥ 5 times / hour accompanied by clinical symptoms such as lethargy. [0003] Apnea is a temporary cessation of breathing during sleep, manifested by a drop in respiratory airflow below 10% of normal breathing amplitude for at least 10 seconds; hypopnea is a drop in respiratory airflow below 50% of normal breathing amplitude during sleep for at least 10 seconds, accompanied by a decrease in blood oxygen saturation ≥ 4% from the baseline level or slight awakening. Repeated sleep apnea during sleep ...
