Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in further detail.
It should be noted that in following specific embodiments, when the embodiments of the present invention is described in detail, in order to
The structure of the utility model is clearly showed that in order to illustrate, spy does not draw to the structure in attached drawing according to general proportion, goes forward side by side
Gone partial enlargement, deformation and simplify processing, therefore, should be avoided in this, as the restriction to the utility model to understand.
Embodiment 1
As shown in Figure 1, a kind of wound dressing based on fluent material oxygen supply, it is characterised in that: dressing is by dressing unit group
At dressing unit is divided into two parts: first part is from top to bottom successively by waterproof membrane 101, hydrogen peroxide storage container 102, protection
Film 103 forms, and the waterproof membrane 101 is located at outermost layer, realizes sealing on the skin for viscous, can use polyethylene (PE),
It can play the role of dust-proof, waterproof, anti-gas-leak, antipollution.Hydrogen peroxide, hydrogen peroxide are stored in the hydrogen peroxide storage container 102
The hydrogen peroxide for the use of concentration being 3%, i.e., medical hydrogen peroxide.Hydrogen peroxide storage container 102 includes polyurethane sponge 104, is used for
Absorption and fixed liquid.To control dressing reaction speed, if the side of hydrogen peroxide storage container 102 is machined in position
Dry aperture, effect are to leak hydrogen peroxide with certain rate and contact catalyst generation oxygen.Hydrogen peroxide is deposited
Storage container 102 uses dark material 105, such as: polyethylene, to prevent hydrogen peroxide oxygenolysis in storage and transportational process.It is double
Hydrogen peroxide in oxygen water storage container 102 can be filled in advance, be easy to use.The protective film 103 can prevent storage, transport
When pollute, when use, opens.Protective film 103 has medical adhesive 106, for dressing is fixed on the skin.
Second part is divided into two layers: first layer is the pack 201 that catalyst and hydrogel particle mixture form.Outer layer
2012 be the material of air-and water-permeable, and internal layer 2011 is network, and polyurethane sponge can be used in network, is used for fixed solid
Particle is uniformly distributed in it in pack.Network size will match with particle size.The effect of hydrogel is for inhaling
Receive the water generated after hydrogen peroxide reaction and wound exudate.Hydrogel material is super absorbent resin (SAP), and material is acrylic acid
And the polymer of sodium acrylate.The dosage of hydrogel depends on three aspects: 1) water absorption: for absorbing the liquid of wound and applying
The liquid stored in material avoids liquid in direct contact with the skin.Therefore its dosage depends on the amount and hydrogen peroxide of wound fluid
Amount.2) reaction speed: the amount of hydrogel is bigger, and the speed that reaction speed, that is, oxygen generates is slower.3) expansion rate after absorbing water.
Expansion rate is excessive, is easy to cause extruding wound or seal failure, chemical spill and release skin.Manganese dioxide is catalyst.
When first part and second part contact, due to the leakage and capillarity of micropore, hydrogen peroxide is stored from first part's hydrogen peroxide
Container 102 leaks out, and contacts catalyst and hydrogel in second part pack 201, and reaction releases oxygen, provides richness for wound
Oxygen environment.
The second part second layer is water absorption pad 202.It is to absorb wound exudate that it, which is acted on, keeps wound surface clean, micro-
It is wet, while allowing oxygen to penetrate again.202 surface of water absorption pad is coated with soft silicone, in direct contact with the skin.Soft silicone is (also referred to as
Silica hydrogel) effect be to make the non-sticky skin of dressing, when opening patient without or mitigate feeling of pain.
The second part surface matcoveredn a and protective layer b in transport, storage, when use, open.
The dressing is easy to use.When storage, two parts are separated.In use, need to only open respective surface protection film
103 and protective layer a301, is sticked together by corresponding position, and two parts corresponding part is respectively equipped with adhered layer, passes through adhered layer
It fits together, guarantees that hydrogen peroxide storage container 102 and pack correspond, be then affixed to wound surface.If you need to shear, only need
According to shape of wound and size, the dressing of corresponding size is sheared, opens internal layer protective layer b302, sticks and be fixed on skin, is infused
Meaning edge reserves the waterproof membrane of one fixed width to realize sealing.It uses respectively not the outer surface of hydrogen peroxide storage container 102 and pack
Same color mark, in use, by hydrogen peroxide storage container 102 and medicine when convenient for the first part of dressing and second part being bonded
Packet corresponds.
Embodiment 2
As in Figure 2-4, the present embodiment difference from example 1 is that, the dressing includes at least one dressing
Unit, multiple dressing units can be with permutation and combination.When for minor cut or wound, dressing area is small, uses single dressing unit；With
When big wound, dressing area is big, if you need to shear, may be designed to multiple dressing units and is arranged in a combination, that designs in this way is good
Place be using when can be sheared according to wound size；Be evenly distributed in dressing surface conducive to reagent, with prevent using when because position,
The phenomenon that concentration of liquid caused by the reasons such as angle flows to side.
Embodiment 3
The present embodiment difference from example 1 is that, at least side of hydrogen peroxide storage container 102 is permeable membrane
(porous membrane) is allowed hydrogen peroxide to be oozed out with certain rate, contacts in pack 201 and generate oxygen after catalyst, the design
Benefit is that hydrogen peroxide persistently permeates and catalyst generates oxygen, can maintain the amount of oxygen of wound surface, avoid failing because sewing.
Polyamide, polyimides, polyether sulfone etc. can be used in permeable membrane material.In storage and transport, due to surface coated with protective film
103, liquid can't leak.
Embodiment 4
The present embodiment difference from example 1 is that, on hydrogen peroxide storage container 102 be furnished with filling liquid hole, filling liquid hole
It is equipped with check valve, hydrogen peroxide is filled with hydrogen peroxide storage container 102 when in use, facilitates in clinical manipulation and use.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its inventive concept is subject to equivalent substitution or change, should all cover the protection scope of the utility model it
It is interior.
