FIG. 3 is a schematic structural view of embodiment 3.
Reference numerals shown in the drawings: 1. a backing layer; 2. a pressure sensitive adhesive; 3. an adsorption type pad; 4. release paper; 5. the easy-to-tear tape 6 and the first release paper; 7. a second release paper; 8. pasting a paper; 9. a first adhesive layer; 10. a second adhesive layer; 11 a third adhesive layer.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
Example 1:
as shown in figure 1, a medical wound dressing of alginate, including backing layer 1, one side of backing layer 1 sets up pressure-sensitive adhesive 2, one side that backing layer 1 was kept away from to pressure-sensitive adhesive 2 sets up absorption type pad 3, the length and the width of absorption type pad 3 all are less than the length and the width of backing layer 1, one side that pressure-sensitive adhesive 2 was kept away from to absorption type pad 3 sets up release paper 4.
When the utility model is used, the release paper 4 is removed, and the adsorption pad 3 is directly covered on the wound position. The utility model discloses a medical wound dressing of alginate is a multi-functional dressing, has safe nontoxic, high hygroscopicity, hemostatic, gelatination nature, promotes wound healing, antibacterial, reduces local pain, stops or reduces the advantage that the scar formed, and be difficult for with the wound adhesion, realize painlessly changing dressings, the general administration and practice thrift uses, the range of application is wide, it is cosmetic in the plastic very much, press sore bedsore and high exudate wound effect better, can realize changing dressings once only to break away from the surface of a wound, no fracture is removed, realize painlessly changing dressings completely.
Further, the adsorption type pad 3 is a water-soluble alginate fiber adsorption type pad. The water-soluble alginate fiber adsorption type pad can shorten dressing change time, save workload of medical staff and disputes between doctors and patients, realize non-adhesion of wounds, remove alginate medical wound dressing at one time during dressing change, leave no residues and realize painless dressing change. The water-soluble alginate fiber adsorption type pad is an ultra-high adsorption fiber and is also a thread-shaped rotating fiber, and can quickly and vertically absorb water/human tissue fluid to quickly form transparent, soft and transparent gel within 5 seconds, so that wound exudate is quickly locked, and the skin around the wound is not easily soaked and injured; the water-soluble alginate fiber adsorption type pad absorbs 2-3 times of the exudation liquid compared with the common alginate fiber.
Wherein the backing layer 1 is a medical non-woven fabric or a medical PU film; be equipped with easily tearing 5 from edge one side of type paper 4, conveniently from the separation of type paper 4 and pressure sensitive adhesive 2.
Example 2:
as shown in fig. 2, the release paper 4 includes a first release paper 6 and a second release paper 7 disposed oppositely.
The easy-to-tear tapes 5 are arranged on the edges of one side, close to the first release paper 6 and the second release paper 7; one side of the back lining layer 1 far away from the pressure-sensitive adhesive is provided with a paster 8.
Example 3:
as shown in fig. 3, the length of the absorbent pad 3 is one third of the length of the backing layer 1, and is located in the center of the backing layer 1, one side of the backing layer 1, which is far away from the pressure-sensitive adhesive 2, is sequentially bonded with the first adhesive layer 9, the second adhesive layer 10 and the third adhesive layer 11 along the length direction, and the first adhesive layer 9, the second adhesive layer 10 and the third adhesive layer 11 are as long as the absorbent pad 3. When a wound is relatively long, two or more alginate medical wound dressings can be used in a combined manner, release paper 4 of the auxiliary materials is removed when the dressing is used, then the adsorptive pads 3 of two adjacent auxiliary materials are close to each other, the pressure-sensitive adhesive 2 at the position of the first adhesive layer 9 on the first auxiliary material and the position of the third adhesive layer 11 on the second auxiliary material adjacent to the first adhesive layer is adhered to each other, then the first adhesive layer 9 on the second auxiliary material or the third adhesive layer 11 on the first auxiliary material is removed, and the dressing is adhered to the position of the first auxiliary material or the second adhesive layer 10 of the second auxiliary material after the second adhesive layer 10 is removed. The utility model is convenient for being applied to the position of a longer wound, and the applicability is improved.
