Description
Technical field
This utility model is related to mask technical field, more particularly to a kind of variable plane-cavate medical protective mask.
Background technology
By those, filter-type respirator wishes that the people that the air of its breathing obtains filtering wears, during including air-breathing, by air
Particulate filter outside, also including the air for filtering exhalation, such as medical personnel mask for needing when patient is treated.Mask
Can be designed to plane form or individual event folded form.Other also have into the such as cup-shaped or duckbill of definite shape
's.
Existing plane formula mask does not have any measure by mask and the face seal of wearer.Therefore, using these mouths
Cover can reserve very big space in mask and wearer's bridge of the nose both sides.This can cause to enter into the filtered of these spaces in a large number
Air be inhaled into so that the function for wearing masks is had a greatly reduced quality.As most of mask is directly connect with the skin of wearer
Tactile type, they do not provide breathing space for wearer, also effective cannot cross air filtering.
Unidirectional-folding formula mask also has the shortcomings that intrinsic.Although unidirectional-folding formula mask can be this to set with extending longitudinally
In respect of its intrinsic shortcoming.The sensitive part such as nose that the folded portion of this mask is often stood in wearer on the face, mouth
Lip etc., this can allow wearer to feel uncomfortable.
The mask or duck-beak type mask of some masks, such as unidirectional-folding, has used tinsel or aluminum strip to make in design
Sealed to eliminate or reduce the gap of mask and wearer's bridge of the nose position for nose clip.But this sealing means are very easy to
Produce deformation and be easy to be stretched.Therefore, the sealing that the pulling force of very little just can be destroyed at wearer's bridge of the nose.
Cup-shaped mask typically adopts hard cup-shaped casing, therefore can not fold, and carries very inconvenient, it is impossible to extensively connect
Receive.Also, cup type mask employs wider aluminum strip as sealing nose clip.And be increase the wide aluminum strip that uses of intensity can not be with pendant
The bridge of the nose position of wearer is fully closely sealed playing a part of excellent sealing.In order to solve this problem, cup type mask is generally adopted
With the belt having compared with hightension, maintain mask in sealing contact with facial by increasing mask to the pressure of wearer's face.
As a result, wear that the very big mask of this pressure brings pain to wearer and to produce its skin of face very deep recessed for a long time
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, so as to allow wearer to feel asphyxia and moist.
Wearer can be also made to grow eczema in some cases.
Although variable plane lumen type mask use it is more relatively easy, it is problematic.Produce this mask needs
The ring of a projection is formed in mask both sides respectively.And the two rings are 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 also just accordingly increased.In addition, on mask base
On fixing band be separately fixed on mask (fixing band is passed through) position.The both sides of first fixing belt, then belt is packaged
Come, such production efficiency is just very low.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 for being adapted to different wearer's heads.
It can be seen that, mask above-mentioned or produce simple cost but can not accomplish and user face seal, or
The sealed horizontal of requirement is reached but due to the complicated high cost of production, it is impossible to satisfactory.
The content of the invention
