Abstract

The invention relates to a multifunctional noninvasive positive pressure ventilation face mask which comprises a face mask body, an inspiratory channel and an expiratory valve channel. A multifunctional installation interface is arranged on the expiratory valve channel; an expiratory valve is arranged in the multifunctional installation interface; the center of the expiratory valve is located at the midpoint of a central axis of the face mask body; the expiratory valve comprises a side hole type expiratory valve or a platform type expiratory valve or a sieve hole type expiratory valve or an adjustable positive end expiratory pressure (PEEP) adjusting valve or a sealing plug; the expiratory valve is connected with the multifunctional installation interface in a matching way through a standard connector; and multiple locking rings are arranged on the face mask body and is matched with locking buckles. The multifunctional noninvasive positive pressure ventilation face mask has the advantages that the noninvasive positive pressure ventilation face mask capable of integrating multiple types of expiratory valves at the optimized position can solve the problem of CO2 rebreathing in the face mask, solve the problem of difficulty in expiratory valve selection for CO2 retention at different degrees, and can solve the problems that an existing face mask cannot independently adjust PEEP and a face part is injured by being pressed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional non-invasive positive pressure ventilation mask. Background technique [0002] Noninvasive positive pressure ventilation (NPPV) refers to assisted positive pressure mechanical ventilation that is connected to patients through non-invasive methods such as nasal masks, oral-nasal masks, and full-face masks. NPPV has become an important technical means for the treatment of various types of acute respiratory failure and the rehabilitation of chronic respiratory failure. However, due to the significant dead space effect in the existing NPPV mask, it is easy to cause carbon dioxide (CO 2 ) gas rebreathing. When NPPV treats chronic obstructive pulmonary disease and other patients with CO 2 When patients are retained, significant CO 2 Rebreathing and higher end-tidal carbon dioxide partial pressure (PetCO) 2 ), may further aggravate the patient's CO 2 Rete...
