Problems solved by technology

[0002] At present, the masks used in hospitals are all filter-type. The exhaled gas of the patient is directly discharged into the ward after being filtered through the mask. Air pollution, even if most of the virus does not escape, can be re-inhaled when the patient inhales, which is not good for recovery
On the other hand, the air pollution in the ward can easily infect the medical staff working in the ward. During the SARS epidemic, the proportion of medical staff infected was very high.

Abstract

The special mouth mask includes a bowl shape mouth mask body and fixing belts. The mouth mask body is connected with an air suction passage and an exhalation passage. The air suction passage and the exhalation passage are respectively disposed with an air suction shutter and an exhalation shutter. The air suction shutter opens inward and the exhalation shutter opens outward. The using method for the mouth mask is to connect the air suction passage with an air intake pipe in sickroom and connect the exhalation passage with an air discharge pipe by soft pipes, the air intake and output pipes in each sickroom are connected to total air intake and discharge pipes to form the special mouth mask respiratory system. The respiratory system has three work modes of natural respiration, ventilation respiration and compulsion respiration. The mouth mask can collect the gas including virus exhaled by patient, and discharge the gas after disinfection to the outdoor air, and reduce the sickroom pollution; the patient can suck outdoor fresh air; the operation operating medical person can reduce the rate of infection by wearing the mouth mask. The invention is simple in structure, low in manufacturing cost and can be easily actualized.

Description

Technical field [0001] The invention relates to a special mask for medical use, in particular to a special mask for a respiratory infection ward and a use method thereof. Background technique [0002] At present, the masks used in hospitals are all filter-type. The exhaled gas of the patient is directly discharged into the ward after being filtered through the mask. Air pollution, even if most of the virus does not escape, can be re-inhaled when the patient inhales, which is not good for recovery. On the other hand, the air pollution in the wards can easily infect the medical staff working in the wards. During the SARS epidemic, the proportion of medical staff infected was very high. The use methods of this type of filtering masks are very simple, either tied on the head with a fixed strap, or worn on the ears. Contents of the invention [0003] The object of the present invention is to provide a kind of special mouth mask and its using method that can collect the exhale...
