Wearing formula nasal cavity connection respiratory mask

Technical Field

The invention relates to a wearable nasal cavity connection breathing mask.

Background

The mask is a sanitary article, is generally worn at the mouth and nose part for filtering air entering the mouth and nose so as to achieve the effect of blocking harmful gas, smell, spray, virus and other substances, has a certain filtering effect on air entering the lung, and has a very good protection effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like. In 2002, China has a severe acute respiratory syndrome, mainly causes droplet infection, and needs to be protected by wearing a mask, in 2019, the novel coronavirus is infected to people through a respiratory system, a main protection measure is that the mask is worn by going out, the mask becomes a main protection measure for diseases transmitted by the respiratory system, but the current medical mask, non-medical mask and newly determined civil sanitary mask have the serious defects that the mask is not tightly sealed due to the fact that the mask is expanded by pressure in oral breathing and nasal breathing, external pollution sources enter the mouth or the lung, eye eyelashes and spectacle lenses can be frosted and fogged under the condition of temperature change, great visual inconvenience and walking danger are brought to a wearer, in addition, the mask is expanded more when the oral breathing and the nasal breathing are carried out simultaneously, the sealing leakage is larger, the probability of the eye eyelashes and the spectacle lenses is higher, and the existing mask filtering systems are on the face, the invention provides a wearable nasal cavity connecting breathing mask, which is composed of a facial mask and a wearable filter, wherein the facial mask is connected with a nasal cavity breathing hose and an oral cavity breathing hose, and the nasal cavity breathing hose is a four-channel hose, the nasal cavity breathing tube comprises two drum-shaped breathing tube plugs with protrusions which can be inserted into two nasal cavities respectively, one ends of other two channels of a nasal cavity breathing hose are connected with a nasal cavity inhalation filter, one ends of the other two channels of the nasal cavity breathing hose are connected with a nasal cavity exhalation filter, a nasal cavity and an oral cavity of a facial mask are separated into a nasal cavity sealed breathing area and an oral cavity sealed breathing area by partitions, the oral cavity sealed breathing area is connected with an oral cavity breathing hose which is provided with three channels, one end of the oral cavity breathing hose is connected with the oral cavity sealed breathing area, one end of the oral cavity breathing hose is connected with an oral cavity inhalation filter, the other end of the oral cavity breathing hose is connected with the oral cavity exhalation filter, the four filters are fixed on a plastic fixing plate at the back of a vest, the filters have two schemes, one, Impeller, this solution is suitable for persons with small lung capacity, such as: children, teenagers and the elderly. The other scheme is that a micro motor and an impeller are arranged on a nasal cavity inhalation filter, a nasal cavity exhalation filter, an oral cavity inhalation filter and an oral cavity exhalation filter, and the scheme is suitable for people with large lung capacity, such as: young and young adults. The filter with the micromotor is composed of a filter box body, the micromotor, an impeller, a fixed seat, an alkaline battery, a circuit board, a switch power line, an active carbon toxicity filtering box, a filter screen, a magnetic type cover, a filter without the micromotor is composed of the filter box body, the active carbon toxicity filtering box, the filter screen, the magnetic type cover, four filter outlets and inlets are formed by connecting hoses to cross shoulders of a waistcoat and reserving four jacks in front of the waistcoat chest, switches of the four filters are also connected to the waistcoat chest by the back to be fixed, an intubation connecting port is connected with four intubation tubes of a facial mask, two mask belts are fixed on two sides of the facial mask respectively, the mask belts can be hung on two fixed facial masks of ears, the nasal cavity connection wearable breathing mask solves the problems of breathing seal, motor power filtration (different can be selected according to requirements), The breathing is smooth, the load is small, all problems that the infection is not easy to happen when the infection source is faced by a back filtering mode are solved, and the problems that the eye eyelashes and the spectacle lenses are frosted and fogged under the condition of temperature change, inconvenience is brought to a wearer and walking danger is brought are solved. Because the nose breathes and is the main breathing mode of the human body, the invention connects the breathing hose with the nasal cavity directly to filter the breathing, solve the leakage caused by the sealing problem, prevent the infection in the air, the nose breathes and the oral cavity breathes and establishes respective channels without mutual interference, and each channel is filtered by an electric filter, so that the wearer does not have the breathing difficulty caused by the breathing pressure, the inhaled and exhaled gases of the nose breathes and the oral cavity breathes are filtered, and the inhaled gases of the wearer are ensured to be non-toxic, sterile and sanitary, the exhaled gases are also non-toxic, sterile and sanitary, if the wearer is an infectious patient, the exhaled gases are also ensured to be non-leakage, and the filtered gases are safe and non-infectious gases, thereby solving the infection path of the infectious patient in the air. The worry poison box, filter screen, magnetism of gauze mask are inhaled formula cover and are used after disinfection, facial gauze mask and four connecting pipe plugs can pull out and carry out disinfection, and filter screen connecting pipe, vest can disinfect the washing, and the product can be used for a long time.

The invention can make the whole process from the nasal cavity to the exhaled air filtration be carried out in a totally closed state, and the filter boxes and filter screens with various safety levels are replaced according to the protection requirements, so the invention can effectively protect various environments such as virus pollution areas, infection isolation areas, air leakage areas, air pollution areas and the like, can also be used as a matched protective article for troops and armed polices in the areas for isolation warning, patrol, combat, rescue and the like, can also be used as a protective product for medical care personnel when serious infectious diseases occur in China, and plays an important role in protecting Chinese from serious virus infection and harmful gas pollution.
