Description

The dressing of a kind of compound medicinal NACF

Technical field

This utility model belongs to new material technology field, relates to biomedical material, specially refers to the design and the structure of a kind of compound medicinal NACF dressing.

Background technology

At present, the medical dressing that is used for the treatment of various wound surface such as burn, scald, granulation atrophy wound, surgical wound has adhesive-bonded fabric dressing, biological dressing and NACF dressing.Existing NACF medical dressing is normally become by the NACF felt.But because the NACF felt is the product that is obtained through the high temperature carbonization activation by the felt that a large amount of very thin short fibers are woven into, the cellosilk that many expenditures are arranged on its surface, original fiber is just very thin, and carbonization-activation has lost a lot of holes on fiber in addition, makes fiber itself fragile especially.When with the topped wound surface of NACF felt medical dressing, the fiber of these expenditures will pressurized and fracture and form the broken end of black fiber and adhere to and be deposited on and be difficult on the wound surface remove, after treating that wound healing skin is grown well, the heavy broken end of staying in the skin of fiber forms irregular " black is tatooed ", the skin that polluted again neither attractive in appearance.So, adopt the NACF felt to have " falling hair " problem as medical dressing.

In order to solve this difficult problem, the someone attempts with gauze NACF felt and patient's wound surface to be kept apart.As CN95206620.3, that is introduced among the CN96205221.3 improves one's methods, its result has not only reduced the NACF felt to the absorption secretions effect that wound surface play, and has damaged the promotion growth effect of ACF felt surface functional group to granulation, and produces the secondary wound again after the wound incrustation.The problem that adopted non-woven fabrics to do " lining " secondary wound afterwards again is to have solved as CN97248977.0, that is introduced among the CN99257580.X improves one's methods, but non-woven fabrics breathability extreme difference, greatly destroyed the effect of the absorption property and the surface functional group of NACF, the NACF felt significantly reduces the therapeutical effect of wound, prolongs the healing stage of wound greatly.Improving one's methods of being introduced among the patent CN99224146.4 is to adopt active carbon fiber fabrics to replace the NACF felt both to solve the difficult problem of " falling hair " as medical dressing, makes the absorption property of NACF and the effect of surface functional group obtain fully playing and embodying again.Yet the adsorption capacity of active carbon fiber fabrics is less relatively, certainly will increase the more number of times of change dressings.

Summary of the invention

The purpose of this utility model provides the dressing of a kind of compound medicinal NACF, utilize activated carbon felt existing a large amount of expenditure cellosilks in surface and active carbon fiber fabrics surface to have fine and close regular crisscross braiding structure, active carbon fiber fabrics is contacted with the tight of felt nature, organically be combined with each other, " falling hair " and active carbon fiber fabrics adsorption capacity with solution NACF felt are little, the problem often of change dressings more is to improve the effect of various wound surface such as NACF dressing treatment burn.

The technical solution of the utility model is design a kind of compound medicinal NACF dressing, and this dressing is to be made of two layers of NACF, or scribbles medical pressure-sensitive adhesive tack coat fabric by two layers of active carbon fibre peacekeeping one deck and constitute.Wherein, internal layer is made of active carbon fiber fabrics, and skin or intermediate layer are made of the NACF felt, and to three layers of dressing, the fabric that skin scribbles the medical pressure-sensitive adhesive tack coat is made of ventilative gauze or non-woven fabrics, is convenient to dressing is fixed on the wound surface.When covering wound with this compound medicinal NACF dressing, active carbon fiber fabrics directly contacts with wound, given full play to the distinctive physics debridement of NACF effect, adsorb exudates such as blood plasma that wound surface oozes out and pus born of the same parents effectively, and the adhesion wound, and promote granulation growth, accelerating wound.Because there is not to fall a mao problem in active carbon fiber fabrics, can not stay black behind wound healing tatoos, and the powerful adsorption capacity that activated carbon felt had, make the more lasting of this compound active charcoal fiber dressing use, reduce the change dressings number of times, alleviated numerous doctors' work and patient's the worry of changing dressings.For the ease of preserving and wrapping, the dressing of this compound medicinal active carbon can be made into the product of plurality of specifications size, directly is enclosed in the packaging bag of the sterilization processing that can carry out disinfection, and also can be soaked with medicine on the internal layer active carbon fiber fabrics, increase the function of its sterilizing, improve therapeutic effect.

Effect of the present utility model and benefit are " falling hair " problems that has solved the NACF felt, NACF can directly be contacted with wound surface, kept the powerful absorbability that NACF had again, it is little to have solved the active carbon fiber fabrics adsorption capacity, the problem often of change dressings more, the medical function of medical activated carbon fiber dressing and absorption property are not fully exerted and embody, make that it is more convenient and practical, high-efficient and lasting, reliable.

Description of drawings

Fig. 1 is the view profile of this dressing,

Fig. 2 is the plan view of this dressing.

Among the figure: 1 is the packing of dressing, and 2 for scribbling the skin of medical pressure-sensitive adhesive tack coat fabric, and 3 is NACF felt intermediate layer, and 4 is the active carbon fiber fabrics internal layer.

The specific embodiment

Be described in detail most preferred embodiment of the present utility model below in conjunction with accompanying drawing.

The dressing of this utility model compound medicinal NACF is to be made of three parts, internal layer is an active carbon fiber fabrics 4, be used to contact wound surface, the intermediate layer is a NACF felt 3, it closely contacts naturally with the internal layer active carbon fiber fabrics, organically is combined with each other, and can strengthen the adsorption of NACF dressing, outer for scribbling medical pressure-sensitive adhesive tack coat fabric 2, its effect is that dressing is fixed on the wound surface skin on every side.Wherein, internal layer active carbon fiber fabrics 4 thickness are 0.1～0.3mm, can make all size size as required, intermediate layer NACF felt 3 thickness are 1～3mm, can make all size size as required, outer tack coat fabric 2 thickness are 0.5～1mm, and specification is more bigger than internal layer and intermediate layer, as shown in Figure 2.Three layers of medical dressing that is composited are loaded in the packaging bag 1 after the sealing, the sterilization that carries out disinfection, use for you to choose.

During use, from packaging bag, take out the dressing that is composited, untie the adhesive tape on the outer tack coat, internal layer NACF cloth cover is directly contacted with wound surface, cover on the wound surface, and outer tack coat is fixed on dressing on the wound surface, avoids coming off of dressing.Active carbon fiber fabrics directly touches with wound surface and contacts, and can adsorb wound secretion timely and effectively, and the auxiliary adsorption of NACF felt has prolonged the service time of dressing.Because active carbon fiber fabrics does not have the cellosilk of expenditure, there is not the depilation problem, so the dressing of this compound medicinal NACF had both kept the absorbability of NACF felt, solved " falling hair " problem and insufficient problem of active carbon fiber fabrics adsorption capacity of NACF felt again.
