Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to a silica gel foam dressing with tensile property.
Background
Wounds, either injured or post-operative, require treatment with wound dressings to absorb excess exudate exuded from the wound, allowing the wound to heal quickly. However, the existing dressing has some defects: the existing dressing can only protect the wound of the wound and can not play a good protection role on the skin around the wound, especially on the wound surface of the joint, the existing dressing can not protect the periphery of the wound surface of the joint under the condition of not influencing the movement of the joint, so that the skin around the joint wound can be eczema or even ulcerated due to the fact that the skin around the joint wound is in a humid environment where penetrating fluid seeps out with bedding or in a long term, the healing of the wound of the joint is influenced, and the pain of a wounded person is greatly increased.
Published chinese utility model patent, application No. CN201620093271.0, patent name: a silicone gel foam dressing, filing date: 2060128, a silicone foam dressing, comprising a film layer, a silicone gel layer and a dressing core layer; after the thin film layer is bonded with the edge of the silica gel layer, placing the dressing core layer between the thin film layer and the silica gel layer; the dressing core layer sequentially comprises a liquid absorbing layer, a flow guide layer and a polyurethane foam layer; the liquid absorbent layer is located on one side of the film layer and the polyurethane foam layer is located on one side of the silicone gel layer. On the one hand, the silica gel foam dressing can fix the absorbed seepage in the molecular structure of the dressing through the liquid absorption layer while increasing the seepage absorption capacity, so that seepage of the seepage is prevented. On the other hand, the silica gel layer has the autohension, and polyurethane foam dressing need not combine sticky tape or bandage to fix when using, and silica gel foam dressing passes through the silica gel layer adhesion in wound, and silica gel layer and wound contact layer viscidity warm sum can guarantee to remove can not the adhesion wound when dressing, reduces painful sense to minimumly to the silica gel layer can repeatedly be uncovered adhesion again, conveniently observes the wound.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides a silica gel foam dressing with tensile property, which comprises a polyurethane film layer 1, a silica gel coating layer 2, a diversion layer 4, a polyurethane foam layer 5 and a semi-permeable film layer 6 are sequentially arranged from bottom to top by taking the polyurethane film layer 1 as a carrier, a sodium polyacrylate layer 3 is arranged between the silica gel coating layer 2 and the diversion layer 4,
the whole silicone gel foam dressing with the tensile property is in a 'wave' strip shape.
Preferably, the polyurethane foam layer 5 is a highly absorbent porous foam.
Preferably, the polyurethane film layer 1 is a bacterium isolation film.
Preferably, the semipermeable membrane layer 6 is a PU film.
Preferably, the semi-permeable membrane layer 6 has a thickness less than the thickness of the polyurethane foam layer 5.
The utility model has the advantages that: elastic polyester foam effectively controls the sepage, locks the sepage and does not impregnate the wound, can prevent infection, provides moist healing environment, reduces dressing change times, alleviates pain, and the whole body design that is "wave" rectangular form laminating body of silica gel foam dressing has tensile properties to promote the healing of edge wound simultaneously.

Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.
As shown in fig. 1-2, the present invention comprises: a polyurethane film layer 1, a silica gel coating layer 2, a diversion layer 4, a polyurethane foam layer 5 and a semi-permeable film layer 6 are sequentially arranged from bottom to top by taking the polyurethane film layer 1 as a carrier, a sodium polyacrylate layer 3 is arranged between the silica gel coating layer 2 and the diversion layer 4,
the whole silicone gel foam dressing with the tensile property is in a 'wave' strip shape.
In use, method of use and effect achieved
In the present embodiment, it is preferable that the polyurethane foam layer 5 is a highly absorbent porous foam.
The structure is arranged, so that the pressure is effectively reduced, the air permeability is good, and the absorption of seepage is promoted.
In this embodiment, the polyurethane film layer 1 is preferably a bacteria-barrier film.
Set up above-mentioned structure, separate the fungus film and guarantee to apply the core clean, ensure not to take place the bacterial infection wound.
In the present embodiment, the semipermeable membrane layer 6 is preferably a PU film.
By adopting the structure, the PU film can evaporate water in the form of vapor and has the functions of water resistance and ventilation.
In this embodiment, it is preferable that the thickness of the semipermeable membrane layer 6 is smaller than that of the polyurethane foam layer 5.
The structure is arranged, and the seepage transfer rate is accelerated.
Opening the package and taking out the dressing, and placing the center of the dressing at the wound; placing the dressing on the wound site, stretching the edges of the dressing according to the size of the wound, wherein the edges can cover intact skin; when the dressing is removed, the polyurethane film layer is firstly uncovered and then is gently removed from the wound; during dressing change, if the dressing is adhered to the wound surface, normal physiological saline can be used for infiltration, and then the dressing can be removed gently. Elastic polyester foam effectively controls the sepage, locks the sepage and does not impregnate the wound, can prevent infection, provides moist healing environment, reduces dressing change times, alleviates pain, and the whole body design that is "wave" rectangular form laminating body of silica gel foam dressing has tensile properties to promote the healing of edge wound simultaneously.
The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application.
