Noninvasive positive-pressure ventilation mask

Abstract

The discloses a noninvasive ventilation mask capable of assisting in fiber bronchoscope interventional diagnosis and treatment and tracheal intubation via fiberoptic bronchoscopy under the condition of no air leakage and on the basis of ensuring continuous noninvasive mechanical ventilation. The noninvasive positive-pressure ventilation mask comprises a mask body, an air bag and a magnifying lens, the air bag can be guided by a fiber bronchoscope to be inserted into trachea intubation, and the magnifying lens can observe a whole process that an inserting structure enters the air bag and is inserted into the nasal cavity. The air bag is cone-shaped or boss-shaped and the like in a manner that the top of the air bag is larger than the bottom of the same, a round hole allowing the fiber bronchoscope to be inserted into or allowing the trachea intubation guided by the fiber bronchoscope is formed in the top of the air bag, and the top of the air bag can be turned up inwardly with the inserting structure and enters the mask body via the bottom of the air bag, so that distance from the top to the nasal cavity can be shortened.

Description

technical field [0001] The invention relates to the technical field of respiratory masks, in particular to a non-invasive ventilation mask capable of performing fiberoptic bronchoscopic interventional diagnosis and treatment operations and fiberoptic bronchoscopic tracheal intubation without air leakage while continuing noninvasive mechanical ventilation. Background technique [0002] Respiratory failure caused by various etiologies requires assisted mechanical ventilation to maintain the patient's vital signs and provide sufficient time for the treatment of the etiology. Assisted mechanical ventilation includes non-invasive mechanical ventilation and invasive mechanical ventilation. Non-invasive mechanical ventilation can reduce invasive mechanical ventilation and shorten the time of invasive mechanical ventilation. When performing non-invasive mechanical ventilation, there are several problems: 1. Sputum suction cannot be performed at the same time during non-invasive mech...

AI Technical Summary

Problems solved by technology

When performing non-invasive mechanical ventilation, there are several problems: 1. Sputum suction cannot be performed at the same time during non-invasive mechanical ventilation. 2. Patients with respiratory failure whose condition cannot be relieved after non-invasive mechanical ventilation treatment, some patients need tracheal intubation for invasive mechanical ventilation. The non-invasive ventilation mask must be removed during the operation of the intubation tube. In this way, the oxygen supply and ventilation of the patient cannot be guaranteed during the whole operation, and fatal hypoxemia may occur; , the intubation valve is fixed on the mask body, and the operator cannot clearly observe the process of the insertion structure entering the nasal cavity, which is not conducive to widespread use
