摘要：
A breather valve for improving the performance of a dual-pressure ventilator, and a breathing device. The breather valve comprises: an inspiration valve cover (1) and an expiration valve cover (9) which are snap-fitted to each other； a diaphragm (5) provided between the inspiration valve cover (1) and the expiration valve cover (9) to form an inspiration valve cavity and an expiration valve cavity； an inspiration one-way valve (3) provided in the inspiration valve cavity； an inspiration one-way valve base (4) provided behind the inspiration one-way valve (3)； an expiration one-way valve plate (7) provided between an expiration pipe joint (14) and the expiration valve cavity for preventing repeated inhalation； an expiration valve opening (6) provided in the expiration valve cavity, wherein when the pressure of the expiration valve cavity is less than that of the inspiration valve cavity, the diaphragm (5) moves to the expiration valve opening (6) so as to close same； and an expiration one-way valve base (8) for supporting the expiration one-way valve plate (7). The diaphragm (5), the inspiration one-way valve (3), and the expiration one-way valve plate (7) match each other so that one of the inspiration one-way valve (3) and the expiration one-way valve plate (7) is open, and the other is closed for preventing repeated inhalation when an inspiration or expiration is made.L'invention concerne une valve respiratoire permettant d'améliorer les performances d'un insufflateur à double pression, et un dispositif de respiration. La valve respiratoire comprend : un couvercle de valve d'inspiration (1) et un couvercle de valve d'expiration (9) qui sont emboîtés l'un dans l'autre； une membrane (5) disposée entre le couvercle de valve d'inspiration (1) et le couvercle de valve d'expiration (9) pour former une cavité de valve d'inspiration et une cavité de valve d'expiration； une valve unidirectionnelle d'inspiration (3) disposée dans la cavité de valve d'inspiration； une base d
