Description

Nasal mask for ventilation

Technical field

The invention relates to a kind of nasal mask for ventilation, especially a kind of cheap and practical nasal mask for ventilation.

Background technology

At traditional nasal mask for ventilation, mostly be in this section zone of its supporting layer extend out to cushion, adopt the single layer structure of hard, can invent the 6th referring to the U.S., 357, No. 441 " Nasal mask and mask cushionthereof " and the U.S. invent " Nasal mask and mask cushion thereof " the 6th, No. 581602, are typical design.

Please referring to Fig. 4 and shown in Figure 5, existing nasal mask for ventilation is by the body 40 of a hollow and contain a Support 41 and formed, a side of 41 is to have one first opening 411 in the Support, and then is to have formed one deck cushion 412 between the circumferential surface of first opening 411 and body 41; Moreover, then be to extend forming one second opening 413 in the surface, inside of this Support 41, and then be to form the supporting layer 414 that contracts in one deck around this second opening 413 towards opening 411 opposite directions.Then extend and form again a contact layer 415 towards first opening, 411 opposite directions again by the outer surface of the supporting layer 414 that contracts in this, and then also form the opening 416 that contracts in corresponding to this second opening 413 at these contact layer 415 places.

This contact layer 415 is directly to contact with user's nose, and supports the whole integrality of commonly using nasal mask for ventilation by this supporting layer 414.By the body that is presented, this supporting layer 414 is to be made by harder plastic material, and this contact layer 415 is then fitted mutually for the nose of wanting energy and user, so it is to use comparatively soft plastic material made.

When this kind nasal mask for ventilation when using, can learn by Fig. 5, its on the stickiness owing to formed an open space 417 between its soft contact layer 415 and the harder supporting layer 414; As user during in the nasal mask for ventilation that uses this kind to commonly use, it fully is to be used as the buffering of fitting with nose by this open space 417, and because the buffering of this open space 417 only limits to the local zone of nose on every side, add that this Support 41 is because of whole nose cup is supported the nose type that meets human body that makes, and need adopt harder material, therefore resulting in this nose cup is subject to fixed shape, and can't satisfy everyone the different demand of nose type, and, make the people produce sense of discomfort easily because this zone is harder material.Further, soft or hard material that supporting layer that this Support 41 is extended out 414 and contact layer 415 are used or thickness neither with, too high really at the cost that penetrates aspect the processing, if mining height cycle pressing technology has the anxiety of fitting and being difficult for or coming off again.

Summary of the invention

The main purpose of nasal mask for ventilation provided by the present invention promptly is to be to provide a kind of tool height stickiness and more comfortable nasal mask for ventilation, solving the above problems.

In order to reach above-mentioned purpose, technological means used in the present invention is to make it to have a body, this body contains a Support, and be to have one first opening and one second opening respectively on the opposite end of this Support, between this first opening and second opening, then be mutual connection by a first passage; Moreover, have an outer cover, it contains a Support, then is to have the 3rd opening corresponding to this first opening in the opposite end of this Support, and the 4th opening corresponding to this second opening, then be to be connected between the 3rd opening and the 4th opening by a second channel.After this body is placed in the second channel of this outer cover, then can see and between this body and outer cover, form one and be looped around the body side face, and be folded in air chamber between this outer cover and body, so when nasal mask for ventilation of the present invention during in use, this air chamber also can be so that this outer cover be fitted on user's the nose nearly except that an excellent sealing cushioning effect can be provided.In addition, owing to contain air chamber between this outer cover and body, when gas inputs to nose cup, because the air chamber in the middle of two supported chamber is connected with second opening and the 4th opening, gas can enter this air chamber makes this air chamber make the expansion of appropriateness, as the water wing air cushion structure, except the nose type that can meet human body and increase the airtight effect, and can be except the buffering of the open space of existing face shield as reinforcement, vertical cushion space of another vertical human body face is provided in addition again, make to only depend on single body side face to support this face shield, and had the advantage that has more comfort level compared to existing.

The specific embodiment

Please referring to Fig. 1 shown in the drawings, Fig. 2, nasal mask for ventilation provided by the present invention is to have comprised a body 10 and an outer cover 20.One suspender belt then is the usefulness that is used for hanging over user's head when using nasal mask for ventilation of the present invention, and is right because it is not to be emphasis of the present invention, so explanation will not explain this suspender belt more thereafter.Moreover this body 10 and outer cover 20 are formed by the elastic material of the inflatable compression of a tool.

Being to have one first opening 11 and one second opening 2 respectively on the opposite end of this body 10, then is the mutual connection by a first passage 100 in this first opening 11 and 12 of second openings.The side face of this first opening 11 is to extend to form a contact-making surface 13, and then is to have formed a ladder 14 on contact-making surface 13; Side face in this second opening 12 then is to have formed a loudspeaker face 15 that extends out.

20 of this outer covers are to have the 3rd opening 21 corresponding to this first opening 11, and the 4th opening 22, the three

openings

21 and 22 of the 4th opening corresponding to this second opening 12 then is to be connected by a second channel 23.At the side face of the 3rd opening 21 is to form a flange 24 corresponding to this contact-making surface 13, then is the sealing surface 25 that contracts in forming at the side face of the 4th opening 22.

Please referring to shown in Figure 3, after this body 10 being placed in the second channel 23 of this outer cover 20, the loudspeaker face 15 that then can see this body 10 is the inner faces that closely fit in the 4th opening 22, that is, this loudspeaker face 15 is the surfaces that closely fit in this second channel 23, simultaneously, this contact-making surface 13 is that the side with this flange 24 contacts, and the bottom surface of this flange 24 then is to join with the surface, top of this ladder 14.Because being the inner faces with this second channel 23, this loudspeaker face 15 contacts, and contact relation this contact-making

surface

13 and 24 of this flanges, between body 10 and outer cover 20, form one and be looped around body 10 side faces, and be folded in the air chamber of 10 of this outer cover 20 and bodies, so when nasal mask for ventilation of the present invention during in use, except this air chamber can provide an excellent sealing cushioning effect can make this outer cover be fitted in nearly on user's the nose, also provide tool flexible support air chamber, making provides more excellent comfortableness compared to existing face shield.
