Description

Anti-snore ventilation mask for patient in department of respiration

Technical Field

The utility model relates to the technical field of medical equipment, in particular to department of respiration patient is with preventing snore face guard of ventilating.

Background

Obstructive sleep apnea hypopnea syndrome (OSAHS for short) is night hypoxemia and sleep apnea caused by repeated upper respiratory tract obstruction, in sleep, muscles of the whole body including pharyngeal muscles and soft palate are in a relaxed state, and tongue root tenesmus are combined to cause upper respiratory tract occlusion, meanwhile, the brain continuously sends signals to main inspiratory muscles (diaphragm muscles) to urge the main inspiratory muscles to continuously work, the activity increases the negative pressure of the respiratory tract, so that the respiratory tract is narrowed and completely closed, and the characteristic hypoxia mode is chronic intermittent hypoxia. The body enhances respiratory movement in order to overcome airway occlusions, and this compensation can lead to nighttime arousals, sleep discontinuities, and dilution of oxygenated hemoglobin. The main symptoms of OSAHS are daytime sleepiness, inattention, morning headaches, snoring, and sleep apnea during sleep. Many clinical studies show that OSAHS has close relationship with other death-causing diseases such as hypertension, diabetes, cerebral apoplexy, coronary heart disease, arrhythmia and sudden traffic accidents, which not only reduces the life quality of patients and damages the health of the patients, but also can cause traffic accidents and production accidents, and has great harm. In recent years, the worldwide morbidity and mortality of OSAHS have been higher, which causes huge social and economic burden, and thus, OSAHS has been recognized as a huge public health problem, and has important significance for diagnosis and treatment of OSAHS.

The current treatment method for OSAHS mainly comprises: health management, medical treatment, surgical treatment, use of oral orthotics and non-invasive positive pressure ventilation (NIPPV), among which NIPPV has proven to be the most successful treatment to date, delivering an air flow at a certain pressure that enters the upper respiratory tract of a patient through the nasal cavity, keeping the blocked respiratory tract unobstructed, and allowing the air to smoothly enter and exit the lungs of the patient, preventing apnea. The therapy equipment which is generally adopted by the device is a noninvasive ventilator, and the device has the defects of large volume, high price, inconvenience in carrying, poor comfort and poor compliance of patients. Meanwhile, the mask for preventing snoring is arranged in the prior art, but when the mask is used, the positive pressure ventilation is continuously carried out on the whole breathing cycle through the sub-turbine no matter whether the patient snores, the patient is easy to breathe uncomfortably when falling asleep, and finally the difficulty in falling asleep is caused.
