Abstract

The utility model relates to a respirator with the nostril breathing tube, comprising an ordinary respirator(1), a plastic cement isolating film(2), a nostril respiration pipe(3), a plastic cement isolating film suture thread(4), a nostril breathing pipe pore(5), a respirator string(6), an expiration valve hole(7), an expiration valve(8). In terms of the characteristic, the ordinary respirator(1) has the plastic cement isolating film(2) inside, and the later part is communicated with the bottom of the nostril respiration pipe(3), the top end of which is provided with the nostril breathing pipe pore(5) whose side wall is provided with the expiration valve hole(7) and the expiration valve(8). The plastic cement isolating film(2) is sealed with the ordinary respirator(1) via the plastic cement isolating film suture thread(4), and the ordinary respirator(1) has the respirator string(6). The utility model is simple in structure, and easy to use. More important, the utility model enables the air to be thoroughly breathed in and then out.

Description

The mouth mask of band respiratory pipe

The utility model relates to a kind of personal breathing protector, exactly is a kind of mouth mask with the respiratory pipe.

Common mouth mask is to be strained and fixed on the face by the mouth mask rope, because people's face structure complexity, common mouth mask can not guarantee fully and face seals, inhaled air is filtered fully, so when serious communicable disease is popular, harm medical personnel and contaminated area personnel's life and health.

The purpose of this utility model provides a kind of mouth mask with the respiratory pipe, and air directly enters nasal cavity via the seal path that common mouth mask (1), plastic cement barrier film (2), respiratory pipe (3) constitute when air-breathing, filters fully; Expiration valve opening (7) and the outlet valve (8) of breath on nostril respiratory siphon (3) during expiration, and common mouth mask (1) exhalation are to overcome the above-mentioned deficiency of common mouth mask.

The utility model is by common mouth mask (1), plastic cement barrier film (2), respiratory pipe (3), plastic cement barrier film suture (4), respiratory pipe pore (5), mouth mask rope (6), expiration valve opening (7) and outlet valve (8) are formed, it is characterized in that there is plastic cement barrier film (2) common mouth mask (1) inboard, the latter is communicated with respiratory pipe (3) bottom, and there is respiratory pipe pore (5) on respiratory pipe (3) top; Respiratory pipe (3) sidewall has expiration valve opening (7) and outlet valve (8).Plastic cement barrier film (2) is sewed up sealing with plastic cement barrier film suture (4) and common mouth mask (1), and common mouth mask (1) has mouth mask rope (6) on the limit.

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Accompanying drawing 1 is a perspective view of the present utility model.

Accompanying drawing 2 is a use principle schematic diagram of the present utility model.

Accompanying drawing 3 is outlet valve structure of the present utility model and operation principle schematic diagram.

Embodiment one:

In the utility model, in common mouth mask (1) inboard plastic cement barrier film (2) is arranged, the latter sews up sealing with plastic cement barrier film suture (4) and common mouth mask (1), plastic cement barrier film (2) is communicated with respiratory pipe (3) bottom, there is respiratory pipe pore (5) on respiratory pipe (3) top, and common mouth mask (1) has mouth mask rope (6) on the limit.

When using the utility model, earlier common mouth mask (1) is attached to face, respiratory pipe pore (5) with two respiratory pipes (3) top inserts in the nasal cavity then, because respiratory pipe (3) is generally by silica gel manufacturing and slightly thicker than the nostril, therefore airtight fully with nasal cavity, fasten and adjust mouth mask rope (6) at last, common mouth mask (1) is close on the face all around.

When air-breathing, the torso model expansion, in nasal cavity, form negative pressure, because of nasal cavity is tightly connected with respiratory pipe (3) top mutually by respiratory pipe pore (5), latter bottom is communicated with plastic cement barrier film (2), plastic cement barrier film (2) uses plastic cement barrier film suture (4) and common mouth mask (1) to sew up sealing again, and therefore the outer contaminated air of common mouth mask (1) can only be after common mouth mask (1) filters, and the path that is made of plastic cement barrier film (2), respiratory pipe (3) enters nasal cavity.And the contaminated air that the slit that forms via common mouth mask (1) and face enters can not enter respiratory pipe (3) and nasal cavity, reaches and filters the air-polluting effect of incoming call fully.

During expiration, the path that the breath via intranasal application is communicated with plastic cement barrier film (2) by respiratory pipe pore (5), respiratory pipe (3) bottom is filtered the back by common mouth mask (1) and discharges.

When using the utility model to speak, the spittle also can be filtered by common mouth mask (1) in mouthful.

Embodiment two:

In the utility model,, can form expiratory resistance if common mouth mask (1) filter course is blocked up.For overcoming this difficulty, on respiratory pipe (3) sidewall, cut out outlet valve (8), the latter's one end still links to each other with respiratory pipe (3) sidewall, outlet valve (8) is tapered, can only open outside respiratory pipe (3), the edge of cutting forms expiration valve opening (7) on respiratory pipe (3) sidewall.

Under the normal condition, because respiratory pipe (3) is generally by the silica gel manufacturing, so outlet valve (8) the one ends formation elastic force that links to each other with respiratory pipe (3) sidewall, outlet valve (8) is pressed on the expiration valve opening (7) both sealings that fit like a glove.

When air-breathing, because in the respiratory pipe (3) is negative pressure, outlet valve (8) is pressed on the expiration valve opening (7) more, be sealed into one, therefore the contaminated air that enters of the slit that forms via common mouth mask (1) and face can not enter respiratory pipe (3) and nasal cavity, reaches and filters the air-polluting effect of incoming call fully.

During expiration, because common mouth mask (1) filter course is blocked up, the gas of exhalation forms higher normal pressure in respiratory pipe (3).When pressure surpass outlet valve (8) one ends link to each other with respiratory pipe (3) sidewall formation, when outlet valve (8) is pressed on elastic force on the expiration valve opening (7), outlet valve (8) is opened, and breath is discharged from expiration valve opening (7).

When the breath normal pressure weakens gradually, less than outlet valve (8) one ends link to each other with respiratory pipe (3) sidewall form, when outlet valve (8) is pressed on elastic force on the expiration valve opening (7), outlet valve (8) cuts out, and outlet valve (8) is pressed on the expiration valve opening (7), be sealed into one, remain breath and discharge through common mouth mask (1) filter course this moment.

Simple in structure being easy to of the utility model used, and air can be filtered fully the back and suck, and be easy to breath.
