Embodiment Construction

[0028] Breathing mask structure

[0029] It includes a mask body 1, an inhalation one-way valve 2, an exhalation one-way valve 3, an exhaust liquid spray device 4 and a flexible air storage bag 5.

[0030] Wherein the mask body is made of materials capable of filtering germs, for example, it can be made of materials meeting N95 standards or similar standards. The mask body is bowl-shaped, buckled on the patient's mouth and face, and fixed by straps (not shown in the figure) to prevent air leakage.

[0031] The mask body is provided with an inhalation one-way valve, which is used to open the valve body when the patient inhales, so that the outside air can enter the mask body without resistance and be inhaled by the patient. And when the patient exhales, the inspiratory one-way valve is closed, and the gas cannot be discharged through the valve body, but can only be discharged through the filter material of the mask body. As a result, the inspiratory resistance of patients wit...

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...
