Description

Band-aid for promoting skin wound healing

Technical Field

The utility model belongs to the technical field of the biological medicine, concretely relates to promote woundplast of skin wound healing.

Background

The skin is the first barrier of the body against external aggressions and is also the tissue of the largest area of the body. The normal and complete skin has the functions of protecting the body from being invaded by external substances and microorganisms, regulating the body temperature, avoiding tissue dehydration and the like. Scratching of skin tissue not only can cause destruction of subcutaneous tissue, but also can affect homeostasis of the body. In daily life, skin injuries can be caused by a plurality of reasons, such as friction, sharp-edged wounds, burns and the like, when skin tissues are injured, the body can start a wound healing process, and if acute skin injuries cannot be normally repaired, chronic and non-healing wounds or hyperplastic scar tissues can be formed.

After the skin surface is damaged, the healing of the wound is a complex and ordered biological process, and the acute wound repair can be roughly divided into four stages of hemostasis, inflammatory reaction, cell proliferation and granulation tissue formation and remodeling. The four stages interact and overlap with each other, and the new tissue replaces the damaged tissue to complete the regeneration process of the tissue. The better wound healing is mainly reflected in the following aspects: (1) the wound part is rapidly stopped bleeding; (2) an appropriate inflammatory response; (3) the epidermal cells are rapidly differentiated to form keratinocyte with strong activity under the external stimulation so as to complete the regeneration process of the epidermis; (4) rapid generation of new blood vessels; (5) collagen is synthesized and deposited properly and rapidly to enhance the mechanical strength of the healing tissue.

After a wound occurs in the skin, a wound dressing is often used to help the wound heal. The use of the wound dressing is favorable for protecting tissues from external physical damage, avoiding secondary pollution of wound surfaces caused by bacteria and the like and promoting normal repair of the wound surfaces. Therefore, a superior wound dressing must have the following characteristics: the wound surface is prevented from secondary damage caused by external microorganisms or other substances; the mechanical performance is good, and the comfort of a user is ensured; the paint is non-toxic and non-irritant, and ensures the safety of users; ensuring the wound surface to have sufficient gas exchange and better wettability; ensuring that the wound dressing does not adhere to tissue when detached from the tissue site, causing re-tearing of the neogenetic tissue.

In the prior art, a large number of synthetic or natural products are used for manufacturing wound dressings, and the most common and widely used wound dressings are woundplasts. Such as those made of polyurethane, are widely used for wounds of various shapes and degrees. In addition, many synthetic polymers or biopolymers are widely used in the development of wound dressings, such as chitosan, polyvinyl alcohol, alginate, cellulose, collagen, and the like. The utility model discloses the people is realizing the in-process discovery of this application embodiment, and woundplast among the prior art is not showing enough to the effect that promotes wound healing, and some cytotoxicity still exists, and anti-infectious ability is poor, and the mechanical properties that self has is poor.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a through providing a promote woundplast of skin wound healing, this woundplast includes lining layer, mucigel, the layer that absorbs water and promotes healing medicine layer, contains mesenchymal stem cell preparation in promoting healing medicine layer, has solved the problem that woundplast among the prior art is not showing enough to the effect that promotes wound healing, has realized the technological effect that promotes the quick healing of wound.

A wound patch for healing an access wound comprising:

a lining layer;

the adhesive layer is arranged on the lining cloth layer and comprises a first adhesive layer and a second adhesive layer which are mutually independent;

the water absorption layer is arranged on the lining cloth layer, the water absorption layer is arranged between the first viscose layer and the second viscose layer, and a gap is formed between the water absorption layer and the first viscose layer as well as between the water absorption layer and the second viscose layer;

a healing promoting drug layer disposed on the water absorbing layer.

And when the band-aid is stuck to a wound part, the soluble soft capsule is contacted with blood or tissue fluid of the wound part, then the capsule wall is dissolved, and mesenchymal stem cell preparations in the capsule are automatically exuded to be contacted with the wound, so that the capsule is not required to be pinched and broken by hands, and the band-aid is more sanitary and convenient to use. The liquid healing promoting medicine is encapsulated in the soft capsule, so that the quality guarantee period of the medicine is prolonged, and the use is more convenient.

Preferably, the distance between the viscose layer and the edge of the lining cloth layer is greater than that between the healing promoting medicine layer and the edge of the lining cloth layer.

The distance between the viscose layer and the edge of the lining cloth layer is greater than the distance between the healing promoting medicine layer and the edge of the lining cloth layer, so that the medicine can be prevented from leaking or overflowing from the band-aid.

Preferably, the thickness of the adhesive layer is less than the sum of the thicknesses of the water-absorbing layer and the healing-promoting drug layer.

The thickness of the adhesive layer is smaller than the sum of the thicknesses of the water absorption layer and the healing promoting medicine layer, so that when the band-aid is stuck on a wound, the medicine can generate a certain 'compression' effect on the wound, and the full contact between the medicine and the wound is facilitated.

Preferably, the first adhesive layer is a strip-shaped spaced adhesive layer.

When the band-aid is used, taking the wound on a finger as an example, the common use method is that the central part of the band-aid is aligned with the wound, then the release paper covered on one of the two adhesive layers is uncovered, the adhesive layer is firstly adhered to the skin beside the wound, namely one end of the band-aid is fixed, then the band-aid is wrapped around the finger, and then the release paper covered on the other adhesive layer is uncovered.
