Oxygen inhalation face mask for reducing spreading of infectious diseases

Abstract

The invention belongs to the technical field of medical instruments, and particularly discloses an oxygen inhalation face mask for reducing spreading of infectious diseases. The oxygen inhalation facemask comprises a face mask body, the upper part of the face mask body is connected with an oxygen inhalation joint, the lower part of the face mask body is connected with an exhaust joint and a sputum suction joint, the exhaust joint is sequentially connected with an exhaust tube and a waste gas treatment bottle, and the sputum suction joint is connected with a sputum suction tube; and the outerside edge of the edge of the face mask is connected with a rear cover, the rear cover extends to the neck of a human body, the face mask body and the rear cover are embraced to form a head placement cavity with the lower end open, and the open end of the head placement cavity is connected with an annular clamping airbag. According to the oxygen inhalation face mask, sputum suction can be conductedsimultaneously with oxygen inhalation, the whole operation of oxygen inhalation and the whole operation of sputum suction are both completed under the closed state, the phenomenon of propagation of diseases in an inpatient ward due to spreading around of sputum, droplets and aerosols, with pathogens, exhaled by infectious disease patients is effectively avoided, the risks of cross infection between the patients and infection of medical care personnel are reduced, using safety is high, and the practicability is high.

Description

【Technical field】 [0001] The invention relates to the technical field of medical appliances, in particular to an oxygen inhalation mask for reducing the spread of infectious diseases. 【Background technique】 [0002] An oxygen inhalation mask is a breathing mask that continuously supplies oxygen to the patient. The oxygen inhalation mask can provide the patient with high-concentration oxygen and high-pressure support to improve the patient's oxygen deficiency and reduce the patient's breathing work. It is important to save the life of the critically ill patient. appliance. The oxygen masks used in hospitals basically have the following problems: [0003] (1) The airtightness is not good. Patients with infectious diseases who can infect through sputum, droplets and aerosols, such as patients with new crowns and patients with respiratory infections of various unknown pathogens, exhaled sputum, droplets and air with pathogens during breathing The sol will spread around, which...

[0004] (2) It is not convenient for sputum suction operation

For example, the Chinese utility model patent CN2627861Y is an on-demand oxygen inhalation and detoxification mask. Although the oxygen inhalation and detoxification mask improves the airtightness of the mask by setting a sealing ring on the edge of the mask, the combination of the sensor, the three-way pipe and the steering control valve allows the patient to exhale. The gas can be sucked away by the suction pump, so as to avoid the spread of the patient's exhaled gas and cause the phenomenon of virus transmission, but the sealing effect is still not good and the patient cannot be suctioned while wearing the mask; and Chinese utility model patent CN209378249U is an oxygen inhalation mask that is convenient for sputum suction operation. Although it can perform sputum suction operation while inhaling oxygen, it cannot control the diffusion of the patient's exhaled gas, so it is not suitable for patients with infectious diseases.
