Abstract

The invention discloses a kind of medical filtration type protective mask, including mask body and the respirator belt being connected to described mask body both sides, described mask body includes that surface layer, sandwich filter intermediate layer and pro-skin internal layer；Described surface layer and pro-skin internal layer acupuncture are compounded in described sandwich and filter on two surfaces in intermediate layer；It is the three-layer type sandwich filter course that non-weaving cloth, nano fibrous membrane and non-weaving cloth are combined successively that described sandwich filters intermediate layer.A kind of medical filtration type protective mask of the present invention, simple in construction, reasonable in design, it filters the structure design in intermediate layer by sandwich, on the one hand improves its protection efficiency to virus in air, on the other hand improves the structural strength of mouth mask, extend its service life.

Description

A kind of medical filtration type protective mask
Technical field
The present invention relates to medical mask field, particularly relate to a kind of medical filtration type protective mask.
Background technology
Medical protective mask, in order to effective particulate crossed in air filtering, intercepts the spittle, blood, body fluid, secretion etc., is used for Infectious microorganism in protection air, bacteria particles thing and treatment use producing in sprayer or electric laser operation Some harmful particulate matters etc., be doctor for preventing respiratory tract infection and surgical infection, stop blood, the master of body fluid communication disease Want approach, thus the requirement to degree of protection is very high.
The filtrate of filter course is the key factor determining medical protective mask strainability quality.But existing medical protection mouth The core of cover is one layer of non-woven filtrate, and it is general that it intercepts barrier propterty, and structural strength is low, and using effect and service life are not Good.
Content of the invention
The technical problem that present invention mainly solves is to provide a kind of medical filtration type protective mask, can solve the problem that existing one The problems referred to above that protective mask exists.
For solving above-mentioned technical problem, one aspect of the present invention is: provide a kind of medical filtration type protection Mouth mask, including mask body and the respirator belt being connected to described mask body both sides, described mask body includes surface layer, sandwich mistake Filter intermediate layer and pro-skin internal layer；Described surface layer and pro-skin internal layer acupuncture are compounded in two surfaces that described sandwich filters intermediate layer On；Described sandwich filters the three-layer type sandwich that intermediate layer is that non-weaving cloth, nano fibrous membrane and non-weaving cloth are combined successively and filters Layer.
In a preferred embodiment of the present invention, described nano fibrous membrane is acetic acid nano fibrous membrane.
In a preferred embodiment of the present invention, the thickness of described acetic acid nano fibrous membrane is 10～50nm, average pore size It is 200～300nm.
In a preferred embodiment of the present invention, described non-weaving cloth is ultra-fine fusion-jetting polypropylene non-weaving cloth.
In a preferred embodiment of the present invention, described surface layer is the nonwoven layer that surface has waterproof ventilated membrane.
In a preferred embodiment of the present invention, described pro-skin internal layer is fine denier polypropylene fibers melt-spun nonwoven layer.
The invention has the beneficial effects as follows: a kind of medical filtration type protective mask of the present invention, simple in construction, reasonable in design, its Filtered the structure design in intermediate layer by sandwich, on the one hand improve its protection efficiency to virus in air, on the other hand carry The high structural strength of mouth mask, extends its service life.
Brief description
Fig. 1 is the perspective view of the present invention a kind of medical filtration type protective mask one preferred embodiment；
Fig. 2 is the decomposing schematic representation of shown mask body；
In accompanying drawing, the mark of each parts is as follows: 1. mask body, 2. respirator belt, 3. surface layer, and 4. sandwich filters intermediate layer, 5. pro-skin Internal layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made and apparent clearly defines.
Referring to Fig. 1 and Fig. 2, the embodiment of the present invention includes:
Embodiment 1
A kind of medical filtration type protective mask, including mask body 1 and respirator belt 2, wherein respirator belt 2 is ear-muff type structure, and It is connected to the both sides of mask body 1.
Described mask body 1 includes that surface layer the 3rd, sandwich filters intermediate layer 4 and pro-skin internal layer 5, and surface layer 3 and pro-skin internal layer 5 Acupuncture is compounded in sandwich and filters on two surfaces in intermediate layer 4.
Described surface layer 3 has the nonwoven layer of waterproof ventilated membrane for surface.
Described pro-skin internal layer 5 is fine denier polypropylene fibers melt-spun nonwoven layer.
The average pore size that described sandwich filters intermediate layer 4 is 8～15 μm, and on the one hand it meet mouth mask user and breathe comfortable Requirement, on the other hand can effectively intercept in the infectious microorganism in air, bacteria particles thing and treatment and use spray Some harmful particulate matters etc. producing in day with fog or electric laser operation, it is achieved real protection effect.This sandwich filters Intermediate layer 4 is the three-layer type sandwich filter course that the 41st, nano fibrous membrane 42 and non-weaving cloth are sequentially compounding by non-weaving cloth, its In, nano fibrous membrane 42 is acetic acid nano fibrous membrane, and its thickness is 10～50nm, and average pore size is 200～300nm；Non-woven Cloth 41 is ultra-fine fusion-jetting polypropylene non-weaving cloth.The structure design of these three layers compound sandwich filter course, on the one hand effectively improves The barrier propterty of mask body, on the other hand, improves the overall construction intensity of filter course, and then improves mask body Structural strength and service life.
Above-mentioned medical filtration type protective mask, it reaches more than 85% to Escherichia coli and staphylococcic bacteriological filtration efficiency.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this Equivalent structure or equivalence flow process that bright specification and accompanying drawing content are made convert, or are directly or indirectly used in other related skills Art field, all in like manner includes in the scope of patent protection of the present invention.
