Abstract

Provided is a medical check air valve respiratory protective mask. The medical check air valve respiratory protective mask comprises a hollow cavity body with three openings, two sides of a middle opening are respectively provided with an opening, piece-shaped one-way valves are arranged in the openings formed in the two sides of the middle opening, one opening only allows air enters the cavity bodies, and the other opening only allows the air to be discharged out of the cavity bodies due to the installation directions of the piece-shaped one-way valves, when a patient wears the medical check air valve respiratory protective mask, fresh air in a ward is sucked in by the air inlet opening, the air discharge opening is connected with a soft pipe which is arranged outside the ward, and the air is discharged into atmosphere after being disinfected. The medical check air valve respiratory protective mask has the advantages of preventing the infection between a doctor and the patient, preventing air with pathogens exhaled by the patient from being inhaled into the body of the patient to cause superinfection, and the like. The medical check air valve respiratory protective mask can be used beyond the field of medical application, for example, the medical check air valve respiratory protective mask can be used in sites such as sewer inner well operations to protect a user from being threatened by toxic gas. The medical check air valve respiratory protective mask is a respiratory protection article which is wide in application.

Description

technical field [0001] The invention relates to a breathing mask, in particular to a medical non-return valve breathing protective mask for preventing respiratory infectious diseases. Background technique [0002] At present, in the clinical practice of prevention and treatment of respiratory infectious diseases, the gauze of medical masks is mainly used to filter pathogens in the air, or laminar flow beds are used. [0003] As of August 7, 2003, Severe Acute Respiratory Syndrome (SARS or SARS) has successively appeared in 34 countries and regions around the world, among which 8,422 suspected cases and 916 deaths were reported. November 2002 During the SARS epidemic until June 2003, hospital medical staff were the most seriously infected. 20% of the infected groups worldwide were medical staff, and 22% of the confirmed cases in Hong Kong were medical staff. Therefore, in order to reduce cross-infection, it is very necessary to strengthen relevant engineering control, especi...
