Intelligent nasal mask fixing system of noninvasive respirator

Abstract

The invention provides an intelligent nasal mask fixing system of a noninvasive respirator, and is applied to the field of noninvasive respirators. The intelligent nasal mask fixing system mainly comprises a respiration mechanism, a connecting pipe, a nasal mask, a fastening tape and a lower fixing mechanism; a respiration monitoring mechanism is arranged in the position, corresponding to the lower part of nares, of the nasal mask and can timely and quickly feed the respiration frequency of a user to a control module of the respiration mechanism so as to synchronize the respiration cycle morerapidly; the respiration monitoring mechanism is simple in structure, exhaled gas downwards impacts a swing piece, so that the swing piece makes contact with a first contact electric piece, an induction circuit forms a loop, then, a signal is sent to a control module for control after being amplified by an amplification circuit, meanwhile, the connecting pipe penetrates through the lower part of the nasal mask to enter the nasal mask, and inhalable gas with certain pressure and temperature can be more accurately sent to the upper respiratory tract of the user while the condition that the inhalable gas circulates in the nasal mask and then enters the nasal cavity due to a gas inlet arranged at the front end is avoided.

Description

technical field [0001] The invention relates to the field of non-invasive ventilators, in particular to an intelligent nasal mask fixing system for non-invasive ventilators. Background technique [0002] Sleep apnea syndrome (SAS) refers to those who stop airflow in the mouth or nasal cavity for more than 10 seconds and more than 30 times within 7 hours of sleep at night. Common causes include deviated nasal septum, nasal polyps, adenoid hypertrophy in the nasopharynx, and macroglossia. , tonsil hypertrophy, mandibular deformity, chronic obstructive pulmonary disease, cor pulmonale, obesity, dyspnea, lethargy syndrome, acromegaly, myxedema, etc., during which there is no spontaneous breathing, as one of the treatments for sleep apnea syndrome As an important means, the use of nasal continuous positive airway pressure (CPAP) can produce rapid and obvious curative effect, in which the use of non-invasive ventilator can continuously and stably supply inhalable gas with certain ...

Problems solved by technology

[0004] The mask of this multifunctional structure often increases the weight of the mask accordingly, and for patients lying on the bed, the heavy mask will seriously affect the comfort, thereby affecting the quality of the patient's rest. The exhalation and inhalation ventilation cycle is often replaced by setting the breathing cycle in the ventilator and the sensor in the ventilator to open the exhalation valve and inspiratory valve. This setting cannot meet the instability of the breathing rhythm. treatment, and the sensor installed in the ventilator also has hysteresis to the monitoring, and the air inlet of the existing nasal mask is often set and the airway tube is often set at the front end of the nasal mask, when the patient lies down, the airway tube and The connection of the nasal mask is supported by air, and the airway is prone to shaking and loosening due to its weight
