Description

Functional dressing for wound healing by liquefying fat

Technical Field

The utility model relates to the technical field of medical equipment, especially relate to a fat liquefaction wound healing function dressing.

Background

The liquefaction of fat in the incision of a surgical operation means that a large number of fat cells in the incision are broken, fat particles in the cells overflow and are decomposed to form liquid fat, and the liquid fat is accumulated in the incision. It is common in patients with thick fat and obesity. Fat liquefaction seriously affects incision healing, increases infection risk, seriously causes septicemia, and has life-threatening effect on sepsis.

The traditional method is to open the incision or remove a part of the suture, even open the whole incision if necessary, and then use the methods of extruding liquefied fat, high-osmotic saline water washing, saline gauze drainage and the like, and then use bandage to press and wrap. The dressing needs to be changed every other day or once a day. The saline gauze has very limited drainage effect, can not adsorb free floating fat drops in the wound, and the wound is soaked in exudate for a long time, so that granulation edema and poor microcirculation affect the healing of the wound and is easy to be infected. Meanwhile, due to long-term and frequent dressing change, patients are difficult to suffer from the pain caused by dressing change, and the workload of medical care personnel is increased.

SUMMERY OF THE UTILITY MODEL

Therefore, an object of the present invention is to provide a fat liquification wound healing functional dressing which is convenient to use and can promote the rapid healing of the wound.

The utility model provides a fat liquefaction wound healing function dressing, include: the functional layer comprises a polyvinyl alcohol foam layer and a hydrogel layer.

Further, the polyvinyl alcohol foam layer is provided with uniformly arranged small holes.

Further, the hydrogel layer is coated around the inner side surface of the support layer, and the polyvinyl alcohol foam layer is arranged in the middle of the inner side surface of the support layer, namely in the middle of the hydrogel layer.

Further, the hydrogel layer is coated on the inner side face of the supporting layer, the polyvinyl alcohol foam layer is arranged in the middle of the inner side of the hydrogel layer, and through holes are uniformly formed in the hydrogel layer at the position corresponding to the polyvinyl alcohol foam layer.

Further, the support layer is a polyurethane film.

Further, the protective layer is release paper or glassine paper.

The utility model discloses utilize medical polyurethane to support compound polyethanol aquogel of membrane, can paste skin fold and pore, it is sealed to laminate completely, makes local formation seal ring border, avoids the incision to receive external infection, and the dry skin around the aquogel only adhesion, the moist wound of non-adhesion can not cause secondary damage and pain when taking off to can prevent that liquid from soaking the subsides and applying the surface, the perpendicular absorption of sepage. Then, a pump effect is formed by utilizing a compressible special polyvinyl alcohol medical biomaterial to generate local micro negative pressure, so that the effects of quickly absorbing incision seepage and draining an incision are achieved. The wound dressing can absorb oozing blood and oozing liquid of the incision integrally, and adsorb liquefied fat drops and the like, meanwhile, the wet environment is favorable for dissolving necrotic tissues and fibrin, so that solid components such as cellulose and protein in the oozing liquid between the incision and the dressing and semi-solid components such as liquefied fat are prevented from remaining, the breeding of microorganisms such as bacteria and the like in the incision is eliminated, the infection chance of the incision is reduced, the tissue metabolism is reduced, the edema degree of the wound surface is reduced, the capillary vessel can be expanded by micro-negative pressure, the microcirculation is improved, the granulation growth is promoted, and the healing of the incision is promoted. And when in use, the seepage is absorbed into the polyvinyl alcohol foam layer in real time, so that the moist environment of the incision can be maintained, the obvious analgesic effect is achieved, the gathering of the seepage of the incision can be avoided, the incision has no scabbing period, the low-oxygen environment can be created, and the scar hyperplasia can be reduced. Can promote the release of various growth factors and up-regulate the activity of the growth factors, and accelerate the healing of the wound surface. Compared with the conventional dressing change, the application of the technology reduces the dressing change times and relieves the secondary injury of the wound surface during dressing change. Meanwhile, the pain of the patient is reduced, the workload of medical staff is relieved, the incision treatment time and cost are greatly shortened, the incision healing quality is improved, and the economic cost of the patient is also reduced.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The embodiment of the utility model provides a fat liquefaction wound healing function dressing, as shown in figure 1, include: the functional layer 2 comprises a polyvinyl alcohol foam layer 21 and a hydrogel layer 22. Preferably, the polyvinyl alcohol foam layer 2 is provided with uniformly arranged small holes; the supporting layer 1 is a polyurethane film; the protective layer 3 is release paper or glassine paper.

In one embodiment of the present invention, the hydrogel layer 22 is coated around the inner side surface of the support layer 1, and the polyvinyl alcohol foam layer 21 is disposed in the middle of the inner side surface of the support layer 1, that is, in the middle of the hydrogel layer 22. Or in another embodiment, as shown in fig. 2, the hydrogel layer 22 is coated on the inner side of the support layer 1, the polyvinyl alcohol foam layer 21 is arranged at the middle position of the inner side of the hydrogel layer 22, and through holes are uniformly arranged on the hydrogel layer 22 at the position corresponding to the polyvinyl alcohol foam layer 21. Wherein, the polyvinyl alcohol foam layer 21 is compressed to generate siphon effect and pump effect similar to syringe to form micro negative pressure, and a row of small holes are uniformly arranged on the compressed dressing to promote the better absorption of liquid.

The utility model adopts polyvinyl alcohol medical biomaterial, which is a completely natural degradable high polymer material with excellent imbibition performance and very soft surface when contacting with human body. The excellent liquid absorption performance is shown in a higher liquid absorption rate and an ultra-strong liquid absorption rate.
