Embodiment 1

[0047] This example provides a band-aid that promotes skin wound healing, as figure 1 shown, including:

[0048] interlining layer 10;

[0049] An adhesive layer, the adhesive layer is arranged on the interlining layer 10, and the adhesive layer includes a first adhesive layer 21 and a second adhesive layer 22 which are independent of each other;

[0050] Water absorption layer 30, the water absorption layer 30 is arranged on the interlining layer 10, the water absorption layer 30 is arranged between the first adhesive layer 21 and the second adhesive layer 22, the water absorption layer 30 and the first adhesive layer 21 and the second adhesive layer the layers 22 have gaps between them;

[0051] The drug layer 40, the drug layer 40 is arranged on the water-absorbing layer 30, and the drug layer 40 contains the mesenchymal stem cell preparation.

[0052] In the Band-Aid of this example, the adhesive layer includes a first adhesive layer 21 and a second adhesive layer 22 th...

Embodiment 2

[0056] This example provides a band-aid that promotes skin wound healing, as image 3 and Figure 4 As shown, the difference between this example and Example 1 is that the drug layer 40 contains a mesenchymal stem cell preparation, and the mesenchymal stem cell preparation is a solid gel of mesenchymal stem cell essence.

Embodiment 3

[0058] This example provides a band-aid that promotes skin wound healing, as Figure 5 and Figure 6 As shown, the difference between this example and Example 1 is that the drug layer 40 contains a mesenchymal stem cell preparation, and the mesenchymal stem cell preparation is a soft capsule of mesenchymal stem cell essence. When in use, first pinch the soft capsule with your fingers to make the mesenchymal stem cell essence infiltrate the water-absorbing layer; then cover the wound so that the essence can directly contact the wound, so as to promote the rapid healing of the wound. You can also use easy-dissolvable soft capsules. When the band-aid is applied to the wound site, the capsule wall will melt after the easy-dissolvable soft capsule contacts the blood or tissue fluid of the wound site, and the mesenchymal stem cell preparation in the capsule will automatically seep out and contact the wound without The capsule is crushed by hand, which is more hygienic and convenien...

Abstract

The invention provides a band-aid for promoting healing of a skin wound and a preparation method. The band-aid comprises a lining cloth layer, an adhesive layer, a water absorption layer and a medicine layer, and the medicine layer contains a mesenchymal stem cell preparation. The problem is solved that a band-aid in the prior art has a non-significant effect of promoting healing of the wound. Theband-aid has the advantage that quick healing of the wound is promoted. The preparation method is simple in technology step, through simple adjustment, the dry-powder band-aid, the gel-type band-aidand the soft-capsule-type band-aid can be prepared, popularization in the market and industrial popularization are easily achieved, and the market potential is great.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a band-aid for promoting skin wound healing and a preparation method. Background technique [0002] Skin is the body's first barrier against external invasion, and it is also the largest tissue in the body. Normal and complete skin has the functions of protecting the body from the invasion of external substances and microorganisms, regulating body temperature, and preventing tissue dehydration. Scratching of skin tissue will not only cause damage to subcutaneous tissue, but also affect the internal balance of the body. In daily life, there are many reasons that can cause skin damage, such as friction, cuts with sharp objects, burns, etc. When the skin tissue is damaged, the body will start the wound healing process. If the acute skin damage cannot be repaired normally, it will Formation of chronic, non-healing wounds or formation of hypertrophic scar tissue. ...
