Description

Skin dressing pad {PAD FOR SKIN DRESSING}

The present invention relates to a pad for skin dressing, and more particularly, to a skin dressing pad used in a skin procedure to remove a portion of skin tissue by perforating the skin with a hollow micro needle.

The improvement of skin tissue excess and sagging due to aging is a global concern, and the demand for skin lifting procedures is increasing due to the continued growth and aging of the beauty market.

The most effective skin lifting procedure is to remove the actual skin tissue. However, surgical therapy (face, forehead, chest lift surgery, etc.) may have side effects. For example, the face may become asymmetric after surgery. Inflammation can cause antibiotics or facial nerve palsy.

Therefore, some invasive, non-invasive therapies, such as fast recovery period and effective equipment for improving sagging skin have been required.

The procedure for meeting these needs refers to a procedure for multiple removal of unnecessary skin tissue in a micro unit at a time without scars or surgery using a microneedle as a method of skin lifting procedure. Specifically, the above-described procedure, first, penetrates the needle through the skin target site, and removes the skin tissue of the pierced part. And by shielding the area from which the skin tissue has been removed, it is a procedure that can induce skin regeneration internally and thereby increase skin elasticity.

However, since a plurality of needles penetrate the skin at the same time, simultaneous penetration may be difficult depending on the folding of the skin, the skin tissue removal site may be non-uniform, and bleeding due to skin tissue removal may occur.

Hereinafter, an embodiment of the skin dressing pad 100 according to the present invention will be described in detail with reference to the accompanying drawings, and in describing with reference to the accompanying drawings, the same or corresponding components are given the same reference numbers, and Redundant description thereof will be omitted.

According to an embodiment of the present invention, the skin dressing pad 100 used in the skin 10 procedure for removing a portion of the skin 10 tissue by drilling the skin 10 by the hollow micro needle 20 As, the skin support layer 110 to planarize the surface of the skin 10 by covering the skin 10 to facilitate the perforation of the skin 10 by the micro needle 20, the skin perforated by the micro needle 20 ( Skin dressing comprising a shrinking layer 130 that shrinks the surface of the skin 10 to close 10), and an adhesive layer 140 for bonding the skin support layer 110 and the shrinking layer 130 to the skin 10 Dragon pad 100 is presented.

As shown in FIG. 1, the lifting skin 10 lifting procedure using a plurality of microneedles 20 preferentially adheres the skin dressing pad 100 to the skin 10 and attaches the microneedles 20. In order to perforate the skin 10 to remove a portion of the skin 10 tissue, and finally, the pad 100 for skin dressing is contracted to close the perforated skin 10 to regenerate the skin 10 in order. It may proceed, and through such a procedure, the skin 10 of the subject can be lifted.

At this time, the skin dressing pad 100 may support the skin 10 to facilitate the perforation of the skin 10 by the micro-needle 20, hemostatic bleeding of the perforation site 12, and perforation It can promote the regeneration of the skin 10 of the site 12.

Hereinafter, each configuration of the pad 100 for skin dressing according to this embodiment will be described in more detail with reference to FIGS. 1 to 6.

The skin support layer 110 may be interposed between the shrinking layer 130 and the adhesive layer 140 as shown in FIGS. 2 and 3. In addition, the skin support layer 110 may be disposed on the lower surface of the haemostatic layer 120.

The skin support layer 110 may cover the skin 10 so as to facilitate perforation of the skin 10 using the microneedle 20 to smoothly support the surface of the skin 10. Specifically, the skin support layer 110 may spread the skin 10 evenly so as to puncture a predetermined position using a plurality of micro needles 20.

As shown in FIG. 1, the skin 10 may have an uneven surface due to wrinkles or the like on the skin 10 due to aging, and the skin support layer 110 adheres to the surface of the skin 10 so that the surface of the skin 10 is Since it can be flattened uniformly, it is possible to perform a puncture safely and effectively.

The skin support layer 110 may be, for example, a flexible film made of synthetic resin, etc., and has a certain degree of stiffness to maintain the basic shape of a flat sheet, so that when the skin support layer 110 adheres to the surface of the skin 10 The surface of the skin 10 may be spread evenly to correspond to the planar shape of the skin support layer 110.

The hemostatic layer 120 may be disposed on the upper surface of the skin support layer 110, as shown in FIGS. 2 and 3, and may stop bleeding that occurs when the skin 10 is perforated by reacting with blood.

The hemostatic layer 120 may cover the perforated portion 12 of the skin 10 as a whole, and contains a hemostatic agent that reacts with blood, so that blood can clot to stop bleeding.

In addition, hemostatic action is also possible through compression of the bleeding site, and thus some hemostatic effect can be achieved by closing the skin 10 by the contraction layer 130 to be described later.

On the other hand, although not shown in the drawing, by applying a hemostatic agent to the skin support layer 110, the skin support layer 110 and the hemostatic layer 120 may be integrally configured as one layer. In this case, the skin support layer 110 may be made of an absorbent material capable of absorbing the hemostatic agent component. In addition, the hemostatic agent may be applied to the shrinking layer 130, which will be described later, to configure the shrinking layer 130 and the hemostatic layer 120 as one layer.

The shrinking layer 130 may be closed by contracting the surface of the skin 10 of the perforated region 12 to promote regeneration of the perforated skin 10, as shown in FIGS. 1 to 3.

Specifically, the shrinking layer 130 may be formed of a stimulus-sensitive material in which contraction occurs in response to temperature, pH, light, moisture, chemical exposure, electricity, and a magnetic field. In addition, the shrinking direction of the shrinking layer 130 may be adjusted as necessary.

When the shrinking layer 130 shrinks according to a change in temperature, the shrinking layer 130 may shrink when it reaches a preset temperature. At this time, if the preset temperature is equal to body temperature, it may have adhered to the skin 10. When the body temperature, shrinkage may occur. Alternatively, when the preset temperature at which the shrinking layer 130 shrinks is set to be lower than the body temperature, the shrinking layer 130 may reach a preset temperature according to a change in external temperature due to cooling or the like, and shrinkage may occur.

In addition, when the shrinking layer 130 shrinks according to a change in moisture content, the shrinking layer 130 may shrink when the moisture contained in the contraction evaporates. When the moisture contained in the shrinking layer 130 evaporates, the volume may be reduced and shrinkage may occur.

4, the shrinking layer 130 may shrink in one direction. When contraction occurs in one direction, the lifting effect of the skin 10 in one direction may be provided in the skin 10 lifting procedure.

As shown in FIG. 5, the shrinking layer 130 may shrink in a first direction and a second direction orthogonal to each other on a plane. Through this, the first direction and the second direction are combined so that shrinkage occurs to provide a tightening effect in all directions on the plane.

As shown in FIG. 6, the shrinking layer 130 may shrink in a direction in which the size of the perforated portion 12 decreases when perforation occurs by the microneedle 20. Specifically, when the physical change occurs by the puncture of the microneedle 20, the shrinking layer 130 may shrink in the direction in which the size of the puncture site 12 is reduced.

For example, when the perforation occurs by the microneedle 20, the shrinking layer 130 may contract only the periphery of the perforation region 12 to close the perforation region 12.

In addition, the contraction layer 130 may include a collagen component to promote skin 10 regeneration.

The adhesive layer 140 may be formed on the bottom surface of the adhesive layer 140 to adhere the skin support layer 110, the hemostatic layer 120, and the contraction layer 130 to the skin 10. The adhesive layer 140 may be formed over the bottom surface of the skin dressing pad 100, or may be formed by patterning in some areas. (See Figure 13)

EGF (Epidermal Growth Factor), etc., beneath any one of the above-mentioned adhesive layer 140, skin support layer 110, hemostatic layer 120, and contraction layer 130 in contact with the skin 10 A substance that aids in regeneration of the same skin 10 may be applied.

The skin dressing pad 100 of the present invention may be made of a transparent material so that the skin 10 can be checked without removing the pad when the skin 10 is attached.

Conversely, the skin dressing pad 100 is opaque to any one of the adhesive layer 140, the skin support layer 110, the hemostatic layer 120, and the contraction layer 130 so that the treatment site is not visible when the skin 10 is attached. It can be composed of one flesh-colored material. In addition, a cover layer of an opaque flesh-colored material may be further included.

Next, the pad 100 for skin dressing according to another embodiment of the present invention will be described with reference to FIGS. 7 to 15.

In the embodiments to be described later, the functions of the skin support layer 110, the hemostatic layer 120, the shrinking layer 130, and the adhesive layer 140 are the same, similar, and there is a difference in the arrangement relationship between them. It will be described for each embodiment with a focus.

In the embodiment illustrated in FIG. 7, the hemostatic layer 120, the skin support layer 110, and the contraction layer 130 may be sequentially disposed on the adhesive layer 140. That is, in the case of this embodiment, unlike the embodiment of FIG. 3, the hemostatic layer 120 may be formed below the skin support layer 110. Therefore, the hemostatic layer 120 is disposed closer to the skin 10 to more stably stop bleeding when bleeding due to perforation of the skin 10 occurs.

8, the skin support layer 110 and the shrinking layer 130 may be sequentially stacked on the adhesive layer 140. Unlike the embodiment of FIG. 3, the haemostatic layer 120 may be omitted.

By applying the hemostatic agent component to the skin support layer 110 or the contraction layer 130, the hemostatic layer 120 may be integrally formed with the skin support layer 110 or the contraction layer 130, or the hemostatic layer 120 Instead of being omitted, the contraction layer 130 may compress the perforated region 12 of the skin 10 and close the perforated region 12 to compress the perforated region 12 to achieve a hemostatic effect.

In the case of the embodiment shown in FIG. 9, unlike the embodiment of FIG. 8, the contraction layer 130 may be disposed on the lower surface of the skin support layer 110, so that the contraction layer 130 is closer to the skin 10 It is arranged so that the skin 10 can be closed more stably.

In the case of the embodiment shown in FIG. 10, the skin dressing pad 100 includes an adhesive layer 140, a first band portion 150 including a skin support layer 110 and a hemostatic layer 120, and an adhesive layer 140 and contraction It may be configured by dividing the second band portion 160 including the layer 130. Here, the first band portion 150 may be formed in the order of the adhesive layer 140, the skin support layer 110, and the hemostatic layer 120 from the bottom.

According to this embodiment, the first band portion 150 and the second band portion 160 are separately formed, so that the first band portion 150 performs the functions of skin 10 flattening and hemostasis, and the second band portion 160 Will perform the function of skin (10) contraction.

First, while the first band portion 150 is adhered to the skin 10, the skin 10 is punctured by the microneedles 20, after which the second band portion 160 is the upper portion of the first band portion 150 It is possible to induce regeneration of the skin 10 of the perforated region 12 by adhering to and contracting the skin 10. On the other hand, after removing the first band portion 150 after the skin 10 perforation procedure, the second band portion 160 may be directly adhered to the skin 10 to close the perforated region 12.

In this case, the hemostatic layer 120 of the first band unit 150 may be integrally formed with the skin supporting layer 110 and a single layer by applying a hemostatic agent to the skin supporting layer 110.

In the case of the embodiment shown in FIG. 11, as in the embodiment of FIG. 10 described above, the first band part 150 and the second band part 160 may be configured, but the first band part 150 has an adhesive layer 140 from the bottom, There is a difference in that it is arranged in the order of the haemostatic layer 120 and the skin support layer 110.

12 and 13, the skin support layer 110 may include an expandable material. The skin support layer 110 expands in contact with the skin 10 and spreads wrinkles on the skin 10 to flatten the skin 10 to provide stability and convenience for the treatment of the skin 10 by the microneedle 20 can do.

The skin support layer 110 may also be formed of a stimulus-sensitive material that reacts to temperature, pH, light, moisture, chemical exposure, electricity, magnetic fields, etc. similar to the shrink layer 130, but unlike the shrink layer 130, it reacts to stimuli. By the expansion can be made of a material.

For example, as the skin support layer 110 adheres to the skin 10, expansion may occur when the temperature reaches a predetermined temperature, that is, the skin 10 temperature.

When the skin support layer 110 is made of an expandable material as described above, as in the case of FIG. 10 or 11, the skin support layer 110 is composed of a contraction layer 130 and a separate band portion, which interfere with each other's contraction and expansion. Will be able to prevent it.

In this case, the adhesive layer 140 may be formed along the edge of the skin support layer 110. In this way, the adhesive layer 140 is formed only on the edge of the skin support layer 110 so that the skin 10 is pulled by the skin support layer 110 more effectively.

Additionally, the hemostatic layer 120 may be formed on the lower surface of the skin support layer 110, and in this case, the hemostatic layer 120 may directly contact the skin 10 and stably hemostatic action may occur.

In the case of the embodiment shown in FIG. 14, the skin dressing pad 100 may be formed in a size to cover the perforations 12 through the microneedle 20 one by one to dress each of the perforations 12.

In this case, a plurality of skin dressing pads 100 according to the present embodiment may be embedded in a microneedle handpiece having a plurality of microneedles 20 for perforating the skin 10, and accordingly, the microneedles 20 When perforating the skin 10 by), first, the pad 100 for skin dressing of the present embodiment may cover the perforation target site.

In the case of the embodiment shown in FIG. 15, the skin dressing pad 100 covers the skin 10 to facilitate puncture of the skin 10 by the microneedle 20 to flatten the skin 10 surface, and It includes a skin care layer 170 that contracts the surface to close the skin 10 perforated by the micro-needle 20, and an adhesive layer 140 for adhering the skin care layer 170 to the skin 10. You can.

In the case of this embodiment, even with a single skin K layer 170, both the planarizing action of the skin 10 before the microneedle procedure and the contraction action of the skin 10 after the microneedle procedure can be caused, so that the pad 100 for skin dressing is more visible. It can be configured compactly.

In addition, since the skin care layer 170 may contain a hemostatic agent component for stopping bleeding that occurs when the skin 10 is perforated by the microneedle, the skin care layer 170 alone may also flatten the skin 10 described above. In addition to the contractile action of the skin 10, it may cause hemostatic action.

As described above, one embodiment of the present invention has been described, but those skilled in the art can add, change, delete, or add components within the scope of the present invention as described in the claims.
