Abstract
The invention discloses a medical waterproof and breathable adhesive tape. The medical waterproof and breathable adhesive tape comprises a transparent silicon layer; a nonwoven fabric layer, a bended coating and an isolating layer are sequentially overlapped on the transparent silicon layer; the bended coating is dipped into the nonwoven fabric layer; the transparent silicon layer is prepared from naon micro-foaming material, and the diameter of the foam is less than that of hydrone. The medical waterproof and breathable adhesive tape has the advantages that (1) the naon micro-foaming material is adopted, which can effectively improve the waterproof and breathable performances of the adhesive tape and keep the wound dry and clean, and thus the wound can heal well; 2) the bended coating is designed, which improves the self-adhering performance and cleaning and disinfecting functions of the adhesive tape, and the adhesive tape can be firmly adhered and does not cause skin irritation and sensitize the skin; 3) the healing condition of the wound can be conveniently observed through the transparent material; 4) the product of different specification can be prepared for the wound of different size, the use is convenient and quick, the material is cheap, and the operation is simple and convenient; 5) the pain caused by general wound closing and stitches removing can be relieved, the stitch can be avoided after healing, and the wound can heal well.
Description
Technical field
The present invention relates to medical adhesive tape field, particularly relate to a kind of medical waterproof and breathable adhesive tape.
Background technology
At surgical site infections, doctor adopts the edge of a knife processing patient in two ways usually, and the first adopts conventional application silk thread, absorbable thread suture operation otch, and then on the edge of a knife, adhere to the thick gauze of multilamellar; It two is directly apply medical wound patch adhesive operation otch.The shortcoming of above-mentioned two kinds of methods is, the former adopts needlework stitching can bring more pain to patient, and easily on the edge of a knife of patient, leaves over cicatrix, affects attractive in appearance, with gauze parcel, its good permeability, but does not have water proofing property; The latter adopts the silicone band with air-vent mostly, fit in the outside of silicone band one deck waterproof ventilated membrane, its advantage is the pain can removing stitching from, has water resistance again, but its permeability is still poor, this be due to one side silicone band non-bore region still in the highest flight, breathability is on the whole not enough, on the other hand, to fit again one deck waterproof ventilated membrane, not only complex procedures, and permeability can be hindered to a certain extent, life-time service can affect the healing of wound.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of medical waterproof and breathable adhesive tape, can solve existing ophthalmic surgical adhesive tape above shortcomings part.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of medical waterproof and breathable adhesive tape, comprise transparent silicon glue-line, sequentially laminated with nonwoven layer, mixed coating and sealing coat on described transparent silicon glue-line, described mixed coating is immersed in described nonwoven layer, described transparent silicon glue-line is nanoscale micro-foaming material, and its cell diameter is less than the diameter of hydrone.
In a preferred embodiment of the present invention, the thickness of described transparent silicon glue-line is 0.05 ~ 0.5mm.
In a preferred embodiment of the present invention, described mixed coating comprises bonding coat and surface conditioning agent coating, and described bonding coat is coated on the surrounding of described nonwoven layer, and described surface conditioning agent coating applications is in the centre of described non-woven fabrics.
In a preferred embodiment of the present invention, described bonding coat is 1/6 of non-woven fabrics width at the coating width that nonwoven layer is every.
In a preferred embodiment of the present invention, described bonding coat is Medical hot melt pressure-sensitive adhesive coating; Described surface conditioning agent coating is conventional medical disinfecting cleaning agent coating.
In a preferred embodiment of the present invention, the width of described medical waterproof and breathable adhesive tape is 3 ~ 10cm, and length is 10 ~ 20cm.
The invention has the beneficial effects as follows: a kind of medical waterproof and breathable adhesive tape of the present invention, tool has the following advantages:
1) by the use of nanoscale fretting map transparent silicon glue-line, effectively improve waterproof and the permeability of adhesive tape, its permeability is good, operative incision can be kept to do clean, be conducive to the healing of wound;
2) by being immersed in the design of the mixed coating in nonwoven layer, effectively improve the autohension of adhesive tape and function that is clean, sterilization, firm pasting, avoids using adhesive plaster and disinfectant in addition again, has easy to use, the non-stimulated and sensitization to skin;
3) transparent material is adopted to be prepared from, the convenient healing state observing wound;
4) product of different size can be prepared into for the wound of different area, convenient to use; Material is cheap, easy and simple to handle, is applicable to the medical institutions of different levels;
5) can reduce pain when routine is sewed up the incision and taken out stitches, otch response light, leave over stitch after avoiding healing, wound healing is attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of medical waterproof and breathable adhesive tape one of the present invention preferred embodiment;
Fig. 2 is the schematic surface of shown mixed coating;
In accompanying drawing, the labelling of each parts is as follows: 1. transparent silicon glue-line, 2. nonwoven layer, 3. mixed coating, 4. sealing coat, 5. bonding coat, 6. surface conditioning agent coating.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of medical waterproof and breathable adhesive tape, comprise transparent silicon glue-line 1, sequentially laminated with nonwoven layer 2, mixed coating 3 and sealing coat 4 on transparent silicon glue-line 1, described mixed coating 3 is immersed in described nonwoven layer 2.
The nanoscale micro-foaming material of described transparent silicon glue-line 1 to be thickness be 0.05 ~ 0.5mm, its cell diameter is less than the diameter 0.4nm of hydrone, gas molecule is only allowed to pass through, and hydrone not by, serve real waterproof and breathable effect, and adopting the method for foaming to make poromerics due to it, distribution of cells is even, improves overall permeability.
