Description
Technical field
The present invention relates to mask technical field, particularly relate to a kind of variable plane-cavate medical protective mask.
Background technology
By those, filter-type respirator wishes that the people that its air breathed obtains filtering wears, during including air-breathing, by air
Particulate filter outside, also include filter exhalation air, such as medical personnel treat patient time need mask.Mask
Can be designed to plane form or individual event folded form.Other also has into the most cup-shaped of definite shape or duckbill
's.
Existing plane formula mask does not has any measure face seal by mask Yu wearer.Therefore, these mouths are used
Cover can reserve the biggest space in mask and wearer's bridge of the nose both sides.This filtered that can cause entering into these spaces in a large number
Air be inhaled into, so that the function worn masks is had a greatly reduced quality.Owing to major part mask is that the skin with wearer directly connects
The type of touching, they do not provide breathing space for wearer, also effective cannot cross air filtering.
Unidirectional-folding formula mask also has intrinsic shortcoming.Although unidirectional-folding formula mask with extending longitudinally, but this can set
In respect of the shortcoming that it is intrinsic.The folded portion of this mask often stands in wearer's such as nose of sensitive part on the face, mouth
Lips etc., this can allow wearer feel uncomfortable.
The mask of some mask, such as unidirectional-folding or duck-beak type mask, employ tinsel in design or aluminum strip is made
Carry out sealing to eliminate or reduce the gap of mask and wearer's bridge of the nose position for nose clip.But this sealing means is very easy to
Produce deformation and be easy to be stretched.Therefore, the least pulling force just can destroy the sealing at wearer's bridge of the nose.
Cup-shaped mask typically uses hard cup-shaped casing, therefore can not fold, and carries very inconvenient, it is impossible to extensively connect
It is subject to.Further, cup type mask have employed wider aluminum strip as sealing nose clip.And be increase intensity use wide aluminum strip can not be with pendant
The most closely sealed effect playing excellent sealing in bridge of the nose position of wearer.In order to solve this problem, cup type mask is generally adopted
With there being the belt of relatively hightension, by adding scale mask, the pressure of wearer's face is maintained being in sealing contact of mask and face.
As a result, wear the biggest mask of this pressure for a long time and bring misery to wearer and to make its skin of face produce the deepest recessed
Trace.
Cup type mask also has a relatively large inner chamber, when wearer breathes air exchange in this cavity and can not
It is discharged outside by mask.This results in that oxygen content in mask is low and humidity increases, thus allows wearer feel to suffocate and moist.
Wearer the most also can be made to grow eczema.
Although variable plane lumen type mask uses more relatively easy, but problematic.Produce this mask needs
The ring of a projection is respectively formed in mask both sides.And the two ring is realized by Shooting Technique, it is desirable to have one with overlap
The belt that mode is inserted.This just makes manufacturing process become relative complex, and cost adds the most accordingly.It addition, on mask base
On fixing band be separately fixed on mask (fixing band process) position.The both sides of first fixing belt, then belt is packaged
Coming, such production efficiency is the lowest.As a result, the end of fixing band is all fixed on upper and lower sealing strip, and the length of belt can not be certainly
By the size being adapted to different wearer's head.
Visible, mask above-mentioned or produce simple cost but can not accomplish and user face seal, or
Reach the sealed horizontal of requirement but high owing to producing complicated cost, it is impossible to satisfactory.
Summary of the invention
The invention aims to solve shortcoming present in prior art, and a kind of variable plane-cavate proposed
Medical protective mask.
To achieve these goals, present invention employs following technical scheme:
A kind of variable plane-cavate medical protective mask, including mask main body, the upper edge of described mask main body is provided with system
Band, the lower edge of described mask main body is provided with frenum, and the upper edge of described mask main body outer surface is provided with the first button loop, the second button
Loop and the 3rd button loop, described suspensorium passes and is fitted in mask main body in the first button loop, the second button loop and the 3rd button loop,
The upper edge of described mask main body inner surface is provided with elastic sealing strip, and the centre position of described elastic sealing strip is provided with button loop A, institute
The both ends stating elastic sealing strip are equipped with button loop B, and the both sides that described elastic sealing strip is detained loop A are equipped with projection, described button
Being provided with curve mouth between loop B and projection, the loop hole between described button loop B and first button loop, button loop A and the 3rd button loop is mutually overlapping
Closing, the two ends of described suspensorium are pierced in the first regulation folder, and the two ends of described frenum are pierced in the second regulation folder, described mask
The horizontal double folded of the main body first half forms fold A, and the horizontal double folded in described mask main body lower half forms fold B, described
Forming horizontal opening between fold A and fold B, described fold A and fold B makes the centre position of mask main body outer surface define
One overlapping layer, is provided with support chip inside described overlapping layer, described support chip supports overlapping layer and forms cavity, in described cavity
Between part be respiratory region.
Preferably, described mask main body includes internal protection layer, filter course and exterior cover sheets.
Preferably, described first button loop is arranged on the edge of mask main body both sides, and described 3rd button loop is arranged on mask master
The centre position of body, it is mask main body length that described second button loop arranges the position distance from the nearest edge of mask main body
1/6-1/4。
Preferably, the height of described overlapping layer is the 1/3-1/2 of mask main body height.
Preferably, the lower edge of described mask main body has through hole, and the width of described through hole is slightly larger than the width of frenum, institute
State frenum through through hole.
In the present invention, having collapsible, easy to carry, processing is simple, and equipment investment is few, and production efficiency is high a little, solves
Conventional planar of having determined mask area is little, and filter efficiency is low, and air velocity is high, the shortcoming that respiratory resistance is big；Absorb cavate mask
Effective area is big, and filter effect is high, and air-flow velocity is low, the advantage that respiratory resistance is little, and overcoming cavate mask can not fold simultaneously,
Not Portable belt, complex process, equipment investment is big, the shortcoming that production efficiency is low.
The feature of the present invention:
One, compared with plane face mask: absorb plane face mask collapsible, easy to carry, processing is simple, and equipment investment is few, produces
Efficiency advantages of higher, overcomes plane face mask effective area little, and filter efficiency is low, and air velocity is high, the shortcoming that respiratory resistance is big.
The point type becoming plane face mask is breathed as cavate breathing.
Two, compared with molding cavate mask: absorb cavate mask effective area big, filter efficiency is high, and air-flow velocity is low,
The advantage that respiratory resistance is little, overcoming molding cavate mask can not fold simultaneously, not Portable belt, complex process, and equipment investment is big,
The shortcoming that production efficiency is low.
