Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] Embodiments of the mask assembly of the present invention, such as figure 1 As shown, it includes a frame and a forehead support 12 swingably arranged on the frame. The frame includes a gasket 113 and a frame body 11 connected to the gasket 113 . The frame main body 11 and the liner 113 can be arranged separately and connected by means of clamping, bonding, etc.; they can also be integrally formed by secondary encapsulation. The liner 113 is made of flexible materials so that it can better and more comfortably contact the human skin, and at the same time fit well with the human skin to ensure airtightness. The frame body 11 also includes an air intake port 112 . A first air outlet 111 is disposed on the frame body 11 near the air inlet port 112 . The first air outlet 111 realizes the communication between the internal environment of the frame body 11 and the exte...

Abstract

The invention provides a mask assembly which comprises a frame, a forehead support and a flow guide component. A first gas outlet is formed in the frame; a second gas outlet is formed in the forehead support; the flow guide component comprises a first end, a second end and a channel, the first end is matched with the first gas outlet, the second end is matched with the second gas outlet, and the channel extends from the first end to the second end and is communicated with the first gas outlet and the second gas outlet. The mask assembly in an embodiment of the invention has the advantages that the exhaust channel arranged between the forehead support and the frame is favorable for exhausting carbon dioxide, accordingly, the carbon dioxide can be prevented from being repeatedly inhaled, and noise generated during gas flow collision can be reduced.

Description

technical field [0001] The present invention relates to assisted breathing equipment, in particular to a mask assembly. Background technique [0002] As we all know, mask components (or breathing masks) are mainly used in the treatment of continuous positive airway pressure ventilation for various respiratory diseases or sleep-disordered breathing. The mask assembly typically needs to be connected to a ventilator in order to provide the breathable gas output from the ventilator to the wearer. [0003] The human body continuously inhales air from the ventilator through the CPAP mask, and at the same time continuously exhales gases such as carbon dioxide. The mask is used as a place for inhaling and exhaling gas, and the exhaled gas can be discharged in time to avoid repeated inhalation of carbon dioxide. Therefore, it is very important to choose the exhaust port in the right position. The exhaust port in the right position is conducive to the emission of carbon dioxide, re...
