Noninvasive mouth-nose switchable ventilation mask

Abstract

A noninvasive mouth-nose switchable ventilation mask comprises a mask body, a flip board, a suspension, a facial cover, a bend, an intake connector, a leak cap, a flip board ring and a flip board silicone sealing pad. The mask body is connected with the facial cover. The suspension is disposed on the upper portion of the mask body. A face board of the mask body is provided with an air vent, an air leak and the flip board. The air leak is closed with the leak cap. The air vent is connected with the intake connector through the bend. The intake connector is connected with a respirator. A nasal mask can be used for ventilation during noninvasive ventilation, thereby ensuring a patient the ventilation effect; the nasal mask and a nasal cover can be switched according to the needs of the patient, the switching function is finished through the flip board, the flip board ring and the flip board silicone sealing pad, the sterilization of the nasal cover and nasal mask and transition time in adjustment are avoided; personal needs of patients are met at the premise of ensuring ventilation, comfort is imparted to patients, and time and labor are saved for medical staff.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a non-invasive mouth-nose switching ventilation mask. Background technique [0002] Some patients with severe respiratory failure or their family members are unwilling to receive invasive mechanical ventilation. In order to help patients overcome the danger, we have tried non-invasive mechanical ventilation first when encountering similar patients in recent years. One of the keys to successful non-invasive ventilation is having the right mask. At present, there are two types of face masks in clinical use: oral and nasal masks and nasal masks. The advantage of nasal masks is that the ventilation volume is stable, but the disadvantage is that patients cannot communicate verbally, which may easily cause flatulence; the advantage of nasal masks is that they can communicate during ventilation, It is not easy to cause flatulence, but the disadvantage is that the ventilation is unstable;...
