Abstract
The utility model relates to a polyurethane hydrogel dressing, which belongs to the technical field of medical supplies. The polyurethane hydrogel dressing consists of three dressing layers, the first is medical barrier paper in contact with a wound, the second is a polyurethane hydrogel, and the third is non-woven fabric; the first medical barrier paper has the effect of isolating the dressing and protecting the wound; the second polyurethane hydrogel has a certain permeability and has favorable plastic and moisture-holding effects, so as to form a favorable environment which can facilitate wound healing; and the third non-woven fabric is used as a support for the polyurethane hydrogel. Therefore, by adopting the polyurethane hydrogel dressing, the formation of scars can be effectively reduced and even avoided.
Description
Technical field
This utility model relates to a kind of dressing, and especially a kind of polyurethane hydrogel dressing belongs to field of medical article technology.
Background technology
After human body was subjected to various burn and scald injuries, the dressing that is used for wound care had traditional oil gauze dressing, activated carbon fiber dressing, composite nano materials dressing or the like.These dressing have effectively promoted the healing of wound with the function of its different characteristics, but the wound just more is often because of changing dressings repeatedly in therapeutic process and because of the adhesion of dressing, or tear because of external force in the process of changing dressings and make wound surface impaired repeatedly, form various hypertrophic cicatriies.These cicatrixes are incomparable except very itching under certain environment, bring outside the discomfort to the patient, and the cicatrix that exsertion parts such as face, hands, foot form also can influence the attractive in appearance of people, bring very big influence for work, family, life confidence and contacts.
The utility model content
The purpose of this utility model is: the weak point at above-mentioned prior art exists proposes a kind of polyurethane hydrogel dressing that can effectively reduce cicatrization.
In order to reach above purpose, polyurethane hydrogel dressing of the present utility model is made of three layers of dressing layer, and ground floor is the medical release paper that contacts with wound, and the second layer is a polyurethane hydrogel, and the 3rd layer is non-woven fabrics.
The medical release paper of ground floor can play the effect of isolating dressing, protection product.The polyurethane hydrogel colloid of the second layer has certain permeability and good plastic, moisture-keeping function, thereby forms a good environment that helps promoting wound healing.Trilaminar non-woven fabrics is as the support of polyurethane hydrogel.Therefore, behind employing this utility model, can effectively reduce even prevent the formation of cicatrix.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Fig. 1 is the structural representation of an embodiment of this utility model.
The specific embodiment
Embodiment one
Present embodiment is that medical burn nursing material is improved the medical polyurethane hydrogel burn dressing that having of back development protected burn wound, promotion healing, suppressed hypertrophic cicatrix.Its structure is made of three layers of dressing layer as shown in Figure 1, and ground floor is the medical release paper 1 of protection product, and the second layer is that polyurethane hydrogel is a non-woven fabrics 3 for 2, the three layers.After the polyurethane suction, formed semipermeable water gel, because the water absorption rate of polyurethane is very big, how controlling its saturation is one of its key problem in technology, polyurethane is under undersaturated situation, has sense of hunger and thirst to moisture content, have the function of shrinking absorption under unsaturated situation, at the empyrosis wound surface initial stage, a large amount of penetrant (water outlet) is inevitable, outside the powerful absorption affinity of unsaturated polyurethanes is enough to penetrating fluid adsorbed to fall, still have enough adsorbances, this adsorbance will produce two effects, the effect of A. mechanical pressure, B. good adhesive force, these effects all can be played ideal inhibitory action to outgrowth cicatrix.
The porosity of polyurethane be decision it is penetrating, suction, slowly return and release moisture content, thereby promote the key of regenerative cell growth.Porosity is too small, can't satisfy requirement penetrating, suction; Excessive its intensity that can make does not again reach specified standard, and repetition test shows that the polyurethane hydrogel porosity is controlled at 50%-60% and is advisable.In addition, being filled with plant extract in the hole of this utility model polyurethane hydrogel---Asiaticoside and human body cell somatomedin can promote wound healing and stop scar hyperplasia.
Usually, burn wound's out-of-flatness, general casting product can't be protected subsides to the wound surface recess, and the polyurethane hydrogel burn dressing of employing present embodiment, because it has excellent plasticity and enough intensity, therefore can be attached to any pouch wound surface, utterly destroy the wound surface dead space.Facts have proved that present embodiment overcomes and fills up the deficiencies in the prior art, have the effect of aseptic, no stickiness, plasticity, half penetrating, balance adjustment wound surface temperature, help inhibition of sintering and scald the wound hypertrophic cicatrix.
