Description

Multi-functional gauze mask of mouth nose breathing disconnect-type of filtration side

Technical Field

The invention relates to the technical field of protective masks, in particular to an air filtering side-mounted mouth-nose breathing separated multifunctional mask.

Background

A mask or a breathing mask is a sanitary product, and generally refers to a tool which is worn at the mouth and nose part and is used for filtering air entering the mouth and nose so as to achieve the purpose of preventing harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer. Wearing a mask or face mask plays a very important role when respiratory infections are prevalent. Especially, when public health incidents occur, a large number of suspicious infected persons, workers in dangerous environments and the like need to wear the mask for a long time to avoid infection, and the breathing mask which is reliable, practical and comfortable to use is the key to avoid spreading of epidemic situations.

Present gauze mask is various, but the filtration face setting is in the oral and nasal part to can't realize the respiratory effective separation of oral and nasal part, oral and nasal exhalation and inspiratory gas all gather in the internal portion of cover of volume limitation, can't avoid repetitive respiration, increased the risk that carbon dioxide stored up and stayed during the long time use and ventilation effect not good, to the patient that has infectious diseases such as periodontitis, can increase the risk that lower respiratory tract infects when current gauze mask is worn. In addition, when the existing mask is worn, if the patient needs to be subjected to operations such as oxygen inhalation, sputum aspiration or bronchoscopy, the mask needs to be removed for operation, so that pathogens are likely to be transmitted in the air, and the risks of polluting the environment and infecting others are increased. In addition, the existing mask can not realize effective mouth and nose breathing separation, and can not open the oral cavity independently, and the mouth and the nose are shielded simultaneously when the patient vomits suddenly, which may cause serious illness or even death. In addition, the existing mask completely shields the mouth and nose parts of a wearer, the mouth and nose parts are important symptom observation parts of respiratory diseases and important human body identity recognition parts, and disease condition observation and personnel identity recognition of the mouth and nose parts cannot be carried out after the existing mask is worn. In addition, the existing mask is fixed through elastic bands behind ears and metal strips of the mouth and the nose, so that the nose bridge, the cheeks and the ears are all pressed, and skin pressure sores are often caused after long-time use.

Therefore, a new protective mask is needed to solve the above problems in the prior art.

Example 2

The air filtering side-mounted mouth-nose breathing separated multifunctional mask is applied to epidemic situation protection, and the multifunctional mask is worn;

the side air filter cavity and the separated mouth and nose mask structure greatly increase the volume of the sealed cavity of the mouth mask, avoid repeated respiration and carbon dioxide retention and enhance the respiration volume and the ventilation effect. The separation of the oral and nasal respiratory tracts also avoids the lower respiratory tract infection risk under diseases such as periodontitis, and in addition, the gas is exchanged between the cheeks at the two sides, so that the air filter cavity layer is prevented from being polluted by oral and nasal secretions, and the use timeliness of the mask is enhanced. The lateral air filter cavity also avoids the collection of the exhaled damp and hot air at the mouth and nose parts, thereby increasing the comfort of breathing and reducing the fogging phenomenon of the glasses. The mouth and the nose are effectively separated, when the mouth or the nose can not breathe or can not breathe conveniently, the independent breathing pipeline can also ensure breathing, and when stomach content is vomited or the lung bleeds, the independent breathing pipeline of the nasal cavity can also ensure breathing.

The air filtering side and transparent cover body structure avoids the mouth and nose parts of the wearer from being shielded, and is convenient for personnel identity identification and patient condition observation of the mouth and nose parts of the patient;

the soft material can well laminate in face to alleviate ear, nose, facial oppression, fixed in headrest portion simultaneously, not only the stationary plane is more firm, and avoided ordinary gauze mask to wear the back skin and pressed the sore. The soft body material can be worn for a long time, is convenient for disinfection treatment, is suitable for disinfection by various methods, and can be repeatedly used by disinfection and air filtration replacement.

Example 3

The application of the mouth-nose breathing separated multifunctional mask with the side air filtering function in the functional treatment and the worn multifunctional mask;

suspected infected patients often have respiratory diseases or chronic diseases, and often need routine oral and nasal care. When the patent mask is worn, the mask can be used for oxygen supply, sputum suction, mouth and nose cavity nursing, bronchoscopy and other operations without taking off the mask through the oxygen inhalation tube, the mouth opening and the nose opening. When the medical staff operates, the wearer does not need to take off the mask, and the breathing gas is still discharged through filtration, so that the pathogen can be prevented from spreading in the air, and the risks of polluting the environment and infecting other people are reduced. Under the long-time wearing state, the wearing staff and suspected patients can use the suction pipe to eat liquid food or spit out mouthwash and oral secretion through the mouth opening, so that the wearing tolerance and safety are enhanced;

when the sealing covers of the mouth and the nose opening are opened, the sleeved diaphragm plays a role in isolation, and when nursing or inspection and other operations are carried out, the sleeved diaphragm wraps medical appliances entering the opening, so that the mouth and the nose opening are prevented from being directly communicated with the outside after being opened, and higher safety is achieved.

In summary, the air-filtering side-mounted mouth-nose breathing separated multifunctional mask solves the technical problems mentioned in the background technology, and is suitable for popularization and application in suspected patients, medical institutions and related work needing protection.
