Breathing mask for preventing cross infection of respiratory infectious disease patients

Abstract

The invention relates to a breathing mask for preventing cross infection of respiratory infectious disease patients, which comprises a mask body, an inspiration one-way valve, an expiration one-way valve, an exhaust liquid spraying device and a flexible gas storage bag, and can ensure that the inspiration resistance is small when the patients normally breathe, the exhaled gas with germs is filtered and then discharged to the environment, and the breathing mask can be quickly exhausted when coughing, so that the breathing effect is good. And gas leakage caused by instantaneous impact force generated by cough is avoided, so that cross infection of a patient in a closed environment can be avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a respiratory mask for preventing cross-infection of patients with respiratory infectious diseases. Background technique [0002] In respiratory wards, there are often patients with infectious diseases. These diseases include tuberculosis, respiratory viral infections, various types of pneumonia, etc. The common feature of these patients is that the exhaled gas contains more germs and is contagious, and these patients are usually accompanied by symptoms such as coughing. [0003] In the prior art, the breathing mask can adopt a closed design to effectively filter germs. For example, a breathing mask that adopts the N95 specification. But this will cause breathing obstacles and aggravate the symptoms of dyspnea in patients with lung diseases. [0004] For this reason, it is proposed in the prior art that a one-way valve is set on the breathing mask, and the one-way...

Problems solved by technology

However, this allows the germs to be directly exhaled into the ward environment, where the patient has been in this environment for a long time, whether breathing or touching will cause cross-infection between the patient or between the patient and the medical staff

[0005] In the prior art, there is also a solution to use a disinfection device to treat the exhaled gas. However, due to the severe cough of the patient with lung disease, the mask and the face will have a gap due to the untimely exhaust of the mask, so that the gas with germs will be discharged from the gap to the environment, causing environmental pollution and cross-infection
