Utility model content
This utility model aims to provide a kind of oronasal mask that can be padded on noninvasive ventilator and patient's face
Between, it is to avoid the oronasal mask humanoid neonychium to the pressure ulcer that patient's forehead, the bridge of the nose and wing of nose both sides skin cause.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
A kind of humanoid neonychium of noinvasive disclosed in this utility model, including viscous layer, decompression layer, outer membrane,
Described decompression is placed between viscous layer and outer membrane, and decompression layer is smaller in size than viscous layer and outer membrane size,
Described viscous layer is connected with outer membrane, and described decompression layer is protected by forehead protection portion, bridge of the nose protection portion and cheek
Being sequentially connected with composition, centre position, described cheek protection portion lower end arranges breach.
Using method of the present utility model: during use, first comparison position, first by humanoid for noinvasive neonychium
Forehead protection portion viscous layer be outwards pasted onto patient's forehead portion by hitting exactly, then paste bridge of the nose protection portion, so
Rear difference pastes forehead protection portion from inside to outside, noinvasive oronasal mask on back cover.
Preferably, described viscous layer is hydrocolloid material.
Preferably, described decompression layer is foam.
Further, described outer membrane is waterproof ventilated membrane.
Further, the edge of described decompression layer is the most thinning.
Preferably, outside described forehead protection portion and cheek protection portion, viscous limit is set.
Preferably, described viscous limit has ductility.
This utility model has the advantages that
1, the humanoid neonychium of noinvasive is between patient's face and oral nose mask, it is possible to alleviate the sense of discomfort of patient,
Decompression, and avoid friction, to reduce the generation even stopping noinvasive nasal mask dependency pressure ulcer;
2, hydrocolloid viscous layer directly pastes patient skin, is avoided that friction, moreover it is possible to absorb what skin oozed out
Perspiration, keeps humidity of skin moderate;
Even if around 3 patient's noses and forehead has wound, it is also possible to use this utility model, because water
Colloid can also promote wound healing;
4, decompression layer is sealed in interlayer by hydrocolloid and outer membrane, can prevent from condensing water-soaked decompression layer;
5, outer membrane is waterproof ventilated membrane, can prevent from condensing water-soaked decompression layer, also can make in decompression layer
Air is discharged, it is possible to ensure the elasticity of decompression layer;
6, the edge of decompression layer is the most thinning, and beneficially neonychium sticks at patient skin;
7, viscous limit can fix neonychium further;
8, viscous limit has ductility, is beneficial to be pasted onto on rough skin.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with attached
Figure, is further elaborated to this utility model.
As shown in Figure 1-2, this utility model includes viscous layer 5, decompression layer 6, outer membrane 7, and reduce pressure layer
6 are placed between viscous layer 5 and outer membrane 7, and decompression layer 6 is smaller in size than viscous layer 5 and outer membrane 7 chi
Very little, viscous layer 5 is connected with outer membrane 7, and decompression layer 6 is by forehead protection portion 1, bridge of the nose protection portion 2 and
Cheek protection portion 3 is sequentially connected with composition, and centre position, cheek protection portion 3 lower end arranges breach 31.
Preferably, viscous layer 5 is hydrocolloid material.
Preferably, decompression layer 6 is foam.
Further, outer membrane 7 is waterproof ventilated membrane.
Further, the edge of decompression layer 6 is the most thinning.
Preferably, outside forehead protection portion 1 and cheek protection portion 3, viscous limit 4 is set.
Preferably, viscous limit 4 has ductility.
Certainly, this utility model also can have other various embodiments, without departing substantially from this utility model spirit and
In the case of its essence, those of ordinary skill in the art can according to this utility model make various accordingly
Change and deformation, but these change accordingly and deformation all should belong to the claim appended by this utility model
Protection domain.
