Specific implementation mode
In order to clarify the technical characteristics of the invention, below by specific implementation mode, and its attached drawing is combined, to this reality
It is described in detail with novel.
As Figure 1-Figure 5, it pressurizes Wound dressing present embodiment discloses a kind of microkinetic, including water-absorption fiber layer 1,
The water-absorption fiber layer 1 is made of superabsorbent fibrous material, upper epidermis 11 is equipped on the top of the water-absorption fiber layer 1, in institute
The lower part for stating water-absorption fiber layer 1 is equipped with layer 12, and the surface of the upper epidermis 11 and layer 12 is by imitating into fiber finer
The processing (as shown in Figure 4) of born of the same parents' structure and hair follicle structure.The water-absorption fiber layer 1 sticks on wound surface 3, and the water suction is fine
Wound surface 3 is completely covered in dimension layer 1, and the area of water-absorption fiber layer 1 is more than the area of wound surface 3, can preferably absorb
The sepage of wound surface 3.Preferably, the distance of marginal portion of the marginal portion of the water-absorption fiber layer 1 to wound surface 3 is
2—5cm.As a preferred embodiment, middle layer 13 is equipped between the upper epidermis 11 and layer 12, described
It is 300-1200 μm of micropore that middle layer 13, which is equipped with several sizes, can vertically absorb and lock the diffusate of wound surface 3 in
In micropore, diffusate is prevented to be spread to surrounding.Using superabsorbent fibrous material, it on the one hand can vertically absorb water and tie and determine sepage in wound
The middle layer 13 of the surface of a wound 3 prevents bacterium from being grown in 3 definite value of wound surface；On the other hand, by upper epidermis 11 and layer 12
The surface treatment of imitative fibroblast and hair follicle structure, can make the part wound surface of a wound 3 after granulation is grown well, when by 3 weeks or so
Between voluntarily grow new skin, without making skin graft.
It is equipped with semi-transparent film layer 2 on the top of the upper epidermis 11, the semi-transparent film layer 2 is the biological semi-permeable that individual event is breathed freely
Film is made (as shown in Figure 5) using polyurethane material；Water-absorption fiber layer 1, and semi-transparent film layer 2 is completely covered in the semi-transparent film layer 2
Area be more than water-absorption fiber layer 1 area.Preferably, the marginal portion of the semi-transparent film layer 2 to the edge of water-absorption fiber layer 1
Partial distance is 5cm.The biological semi-permeable film breathed freely using individual event, can either ensure dressing patch in the non-surface of a wound skin of human body,
The eubolism of healthy skin, and can ensure that the steam on surface of a wound part surface layer smoothly appears.The good moisture-inhibiting of biological semi-permeable film
Performance is mainly the micropore due to there is 1-100 μm in its structure, and a diameter of 0.004 μm of vapor can conveniently be made to penetrate.
When using dressing, water-absorption fiber layer 1 is pasted on wound surface 3 first, it is fine that semi-transparent film layer 2 is then affixed on water suction
The top for tieing up layer 1, plays the role of fixed water-absorption fiber layer 1 in wound surface 3.Since wound is completely covered in water-absorption fiber layer 1
The surface of a wound 3, and the area of water-absorption fiber layer 1 is more than the area of wound surface 3, one side superabsorbent fibrous material absorbs sepage expansion,
And semi-permeable membrane prevents the expansion of water-absorption fiber, and to produce microkinetic, 0- is carried out to the skin around the surface of a wound and the surface of a wound
The microkinetic of 7kpa is pressurizeed；On the other hand, the Air permenbility of semi-permeable membrane be 400-800g/ (㎡ for 24 hours), and damage the steam of skin
Be evaporated to 3000-5200g/ (㎡ for 24 hours), between pressure difference also produce microkinetic and pressurize to the surface of a wound.To make this
There is microkinetic pressurization Wound dressing above-mentioned two microkinetic source to pressurize to the surface of a wound.Microkinetic is carried out to the surface of a wound to be pressurized with
Conducive to surface of a wound blood fortune is promoted, promotes the blood around the surface of a wound within the scope of 2-5cm to transport and increase to surface of a wound direction, accelerate wound healing, together
When also can voluntarily be closed the surface of a wound of 5cm or so.In addition, during the use of dressing, can will be applied according to the area of wounds
Material is cut into corresponding shapes and sizes.
As a preferred embodiment, according to the different seepage discharges of wound exudate, the thickness of the water-absorption fiber layer 1
For 2mm -10mm.
As a preferred embodiment, easy to use for semi-transparent film layer 2, the semi-transparent film layer 2 is being covered in
Before water-absorption fiber layer 1, it is equipped with outer lining 21 on the top of the semi-transparent film layer 2, the outer lining 21 is hard plastic material, can
Preferable support force is provided for semi-transparent film layer 2, prevents semi-transparent film layer 2 from generating deformation during storage.In the semi-transparent film layer 2
Lower part be equipped with liner layer 22, the liner layer 22 is paper material, opens more convenient, while being played to semi-permeable membrane layer 2 anti-
The effect of dirt.When using semi-transparent film layer 2, liner layer 22 is taken off from semi-transparent film layer 2 first, semi-transparent film layer 2 is covered in suction
On water cellulose layer 1, then outer lining 21 is taken off from semi-transparent film layer 2, completes covering of the dressing on the surface of a wound.
To sum up, the utility model plays the role of increasing surface of a wound blood fortune, can speed up the surface of a wound and be cured by pressurizeing to the surface of a wound
It closes, infection control, making the part surface of a wound that need not make skin graft can fully recover, and can be used in operative incision without dressing, reduce patient's pain
Bitter and clinician and nursing work load.
Place is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.Finally illustrate, with
Upper embodiment is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to preferred embodiment to the utility model
It is described in detail, it will be understood by those of ordinary skill in the art that, the technical solution of the utility model can be repaiied
Change or equivalent replacement should all cover without departing from the objective and range of technical solutions of the utility model in the utility model
Right in.
