Description

[0001] The present invention relates to a patch for wrinkle improvement using a shape memory alloy,

The present invention relates to a wrinkle removing apparatus, and more particularly, to a wrinkle removing patch using a shape memory alloy.

The skin is located on the outermost side and consists of the epidermis peeled off when blisters are formed and the dermis and subcutaneous fat layer in it. Wrinkles are usually creased as the epidermis and dermis become less adherent, resulting in a decrease in moisture and subcutaneous fat as the collagen and elastic fibers in the dermis are damaged, or the cells and capillaries at the epidermal and dermal boundary are reduced. do.

The main causes of wrinkles are skin aging, which occurs around 20 years of age, and sun aging due to the sun's ultraviolet rays. The fine wrinkles formed by aging of the skin decrease collagen in the dermal layer of the skin. The epidermis, which loses its elasticity, appears to increase, and deep wrinkles are known to be caused by excessive action of the muscles under the skin.

In addition, age, skin aging and daylight aging in addition to wind, heat, nicotine, lack of exercise, inappropriate diet, alcohol abuse, stress, etc. to promote the aging of the skin to act as a cause of wrinkles.

Therefore, many people have spared a lot of effort using surgical plastic surgery, botox injection, massage, functional enhancement cosmetics, etc. to remove wrinkles that have already occurred.

However, despite attempting various wrinkle removing methods as described above, it is difficult to completely remove wrinkles that have already been formed, so that it is difficult to achieve a great effect and there is a problem that an economical burden is caused.

A patch using a shape memory alloy has recently been proposed to remove wrinkles. Republic of Korea Patent No. 10-0854268 "Wrinkle strip removal patch using the shape suppression alloy" can be seen an example of using a shape memory alloy to remove the wrinkles.

However, the above patent document has proposed a method of spreading wrinkles using the memory capacity of the shape memory alloy, but did not have the wrinkle effect effectively due to some problems. A problem of the present invention will be described with reference to FIG. 1 showing a patch according to the related art.

First, the patent document proposes a patch 10 in which the end of the deformable member 3 having the buffer portion 5 is fixed to the pad 1 by the mold holding portion 2, but the buffer portion 5 is Processing is difficult, and there is a hassle to fix both ends of the deforming member 3 by the mold holding part 2.

Secondly, when the patch is attached to the skin surface, the deformable member 3 responds to the curvature of the skin so that the deformable member 3 does not come into close contact with the skin surface effectively, but there is a problem of lifting or spacing.

Third, the plurality of deforming members 3 used in one pad not only have different lengths, but both ends of the deforming members 3 must be fixed to the mold holding part 2 so that the deforming members by the attachment portion or the size ( 3) They have to be manufactured differently, so it is difficult to use the deformable members interchangeably, manufacturing is difficult, and manufacturing costs are increased and manufacturing labor is increased.

Fourth, since each deforming member is arranged to be distributed at a predetermined interval on the pad, since the tensile force due to the memory capacity is dispersed, there is a disadvantage that the concentration of the tensile force acting on the wrinkled surface is lowered.

Fifth, the tensile force due to the memory capacity of the shape memory alloy can be maximized when the patch is applied so that it acts in the direction perpendicular to the wrinkles. However, when the patch is attached, it is necessary to know the attachment method, and the adhesion of the pad to the curvature of the skin. As a result, the pad and the skin are not sufficiently adhered because the deforming member is not in intimate contact with the skin surface, and therefore, it is difficult to sufficiently transmit the tensile force due to the memory capacity to the skin.

Sixth, when the shape memory alloy of black metal is exposed to the outside and the pad is attached to the face, the aesthetic view is not good.

The present invention is to solve the above-mentioned conventional problems, an object of the present invention is to provide a patch for improving wrinkles effective for local wrinkle removal.

According to an aspect of the present invention, the present invention allows the shape memory alloy to be in intimate contact with the skin corresponding to the curvature of the skin, the restoration of the shape memory alloy form by the memory function acts radially outwardly wrinkles through the shape memory alloy The removal effect can be greatly improved, and it is not necessary to process the buffer part in the shape memory alloy, and the shape memory alloy can be shaped by the size, so that the manufacturing work can be greatly reduced and the manufacturing cost can be greatly reduced. And a patch for improving wrinkles using a shape memory alloy.

Wrinkle improvement patch of the present invention for achieving the above object is made of a core member consisting of a shape memory alloy and a pad having an adhesive surface for bonding the skin to one side of the core member.

According to one aspect of the present invention, the core member has a spiral spring shape and is configured to expand in a radial direction by body temperature, and the pad has a core member embedded therein, and the core member can be stretched in the radial direction when the core member is spread radially outward. It may be made of an elastic material.

At this time, the core member may protrude to one side with respect to the periphery of the core member in the spiral spring shape in the direction of the rotation center axis.

Further, the pad may be formed of a circular or elliptical pocket to embed the core member.

In addition, the core member may be installed in the pad by an insert molding method when forming the pad.

In the present invention, it is preferable that at least one end of the core member forms a curl so that the curved portion touches the pad, thereby preventing the sharp portion of the end of the core member from tearing the pad or touching the skin.

In the present invention, the core member may be made of a bi-directional shape memory alloy. The first form at low temperature has a form that is convenient for application and handling on the skin, and the second form, which comes into contact with the skin by body temperature, makes it suitable for straightening the skin to correct wrinkles.

Meanwhile, in the present invention, the pads may be composed of two parts separated from each other at both ends of the core member.

In this case, the core member is formed to be elongated in one direction, and a deformation portion is formed in the middle thereof, so that the distance between the pads can be increased while the deformation portion is restored to its original shape when the shape is restored by body temperature.

According to the present invention, it is possible to provide a wrinkle improvement patch having a direct effect on local wrinkle removal.

In particular, when the core member made of a shape memory alloy is integrally formed in a spiral spring form (or a spring shape), the memory capacity of the shape memory alloy acts radially outward so that the present invention is not limited to the difference in the wrinkle shape of each part of the face. It can spread out wrinkles effectively.

In addition, in the case of the spiral spring form, due to the elasticity of the material, the center can be elastically projected to the periphery in the direction of the rotational center axis in correspondence with the curvature of the skin, so that the pads are in close contact with the skin surface without lifting or spaces. So that the wrinkle removing effect can be improved in three dimensions. At this time, the spiral spring can be made to slightly protrude from the center of rotation with respect to the periphery in consideration of the convex curvature of the skin from the spiral spring shape, but the spiral spring is elastically corresponding to the skin shape without a separate protrusion. It is easily deformed, so that the effect of skin adhesion can be obtained.

In addition, when the shape memory alloy is manufactured in the form of a spiral spring, it is integrated and easy to manufacture, can reduce the manufacturing cost, and can significantly reduce the number of assembly work.

Hereinafter, some embodiments of a patch for improving wrinkle wrinkles using a shape memory alloy according to the present invention will be described in more detail with reference to the accompanying drawings.

FIGS. 2 to 4 are an exploded perspective view, a longitudinal section, and a plan view showing the core member of the patch for improving wrinkles according to an embodiment of the present invention, and FIGS. 5 and 6 are cross- A perspective view, a plan view, and a side view of a storage alloy.

The pads 102 of the patch 100 according to the invention shown in FIGS. 2 and 3 are manufactured in a substantially circular shape of a silicone rubber material. The pad 102 has a space between the circular upper surface 102a and the lower surface 102b, and the core member 200 is provided in the space. The core member 200 is formed of a shape memory alloy, and the adhesive 101 is applied to the lower surface 102b of the upper and lower planes to the outside to form an adhesive surface. The adhesive surface is usually covered with a release paper 300, and when the release paper 300 is used, the release paper 300 is removed and attached to the skin. Instead of using the release paper 300, a method of forming an adhesive surface immediately before skin adhesion may also be used. The adhesive surface may be formed by attaching a double-sided tape or the like instead of applying the adhesive. Adhesive that forms the adhesive surface is a material that touches the skin directly, so it should be made of a material with little or no harm to the human body.

The pad 102 may be made of a material other than silicon and may be formed of soft and stretchable soft material so that the core member 200 can be stretched sufficiently with the deformation when the core member 200 is deformed by the memory capacity of the core member 200 To form.

The shape memory alloy core member 200 is an alloy having a memory ability to return to a form before deformation when heated to a predetermined temperature, that is, a temperature of 35 ° C. to 38 ° C., even when deformed at a low temperature below room temperature. As the storage alloy, a copper-zinc-aluminum alloy, a copper-aluminum-nickel alloy, a nickel-titanium alloy, or the like is often used.

Here, the core member 200 is formed in the form of a spiral spring that is frequently used for clockwork, and the pad 102 may be formed in a circular or elliptical shape. Since the pad forms a kind of pocket having a space between the upper and lower surfaces 102a and 102b in a circular shape, the pad can be used by placing the core member 200 in the pocket and sealing the inlet so that the core member does not come out. .

In this state, the outermost part of the spiral spring-shaped core member 200 is not shown here, but the outermost part of the pad 102 having a circular shape is formed when the outermost part of the spiral spring form a ring shape that is wrapped around one or more rotations close to the closed curve. It comes in contact with the periphery and in the pocket. Then, if the core member 200 is restored so that the curvature radius of each part of the core member 200 is increased by the body temperature, the outline of the core member is still limited by the pocket space in the pad 102, but the pad 102 Because it is made of elastic silicone-like material, it is approximately circular, but has a larger radius of curvature and a radially enlarged outline.

Along with this, the pad 102 is also circular in shape, and if the adhesive surface of the pad 102 is adhered to the local part of the skin, the skin is enlarged and the wrinkles are stretched as the pad is enlarged at the portion thereof.

In this case, the center end portion and the peripheral outer end portion of the spiral spring-shaped core member 200 are freely deformed (with increasing curvature radius) as the core member 200 decreases in the pocket of the pad 102. It is preferable that it is not particularly fixed to the inner surface of the pocket of the pad 102 so as to be able to be used.

At this time, when the core member 200 is deformed in the inside of the pocket while sliding on the inner surface of the pad 102, the soft pad is not damaged, and the patch 100 is exposed outside the pad 102, In order not to damage the skin, the end of the core member 200 is preferably formed to form curls. It is preferable that the outer end forms a curl since both of the ends, particularly the outer end, are likely to touch the side surface of the pad while transmitting force.

The curl can also be formed by winding the end in a winding shape (rolling up) so that a sharp cut surface is located inside the curl and outwards so that the curved portion of the metal line of the shape memory alloy forms the core member 200. In FIG. 4, reference numeral 201 denotes a curl of which the end of the shape memory alloy core member 200 is rounded off so that the end of the shape memory alloy core member 200 does not stick to the skin.

The core member 200 made of a shape memory alloy may be formed of a wire rod having a predetermined thickness and width, and the outermost portion may be manufactured to form a circular or elliptical shape. It is useful for removing fine wrinkles having relatively low depth of wrinkles, and an elliptical core member can be particularly useful for removing deep wrinkles. This is because the elliptical shape in which the long axis and the short axis are divided may increase in proportion to the deformation caused by the memory capacity acting in the short axis direction due to the length of the long axis.

In the above embodiment, the silicon pad 102 may be expected to have an effect of removing wrinkles by attaching a patch 100 having a spiral spring-shaped core member 200 embedded therein on only the wrinkles, depending on the area to be attached. .

As a result, when the patch of the above embodiment is attached to the skin surface, the shape memory alloy is deformed radially outward in all sections of 360 degrees in the plane while tensioning the wrinkles radially outward as shown in FIG. . The effect of the tensile force can greatly improve the wrinkle removal effect using a long-term patch.

In FIG. 7, reference symbol CL denotes a rotation center axis of the core member 200. Here, the core member forms a spiral spring-like shape, and at the same time, the central end of the core member protrudes slightly to the right of the peripheral portion to form a spiral coil. The degree of protrusion may be formed by artificially adjusting the skin according to the curved surface of the skin where the patch is attached. The core member 200 is initially attached to the skin without protruding, and may be easily deformed according to the curved surface of the skin to form a spiral coil.

The advantage of the patch according to the above embodiment is that the memory capacity acts radially outward and easily deforms in the axial direction of the coil, thereby providing an effect of unfolding three-dimensional wrinkles. In particular, the present embodiment has wrinkles around the edges of the eyes or the mouth. And very useful for removing forehead wrinkles.

On the other hand, the above has been mainly described an embodiment in which the core member is embedded in a pad of a circular or elliptical pocket form, which is made by placing the core member between the upper and lower surfaces, and bonding the upper and lower peripheral portions, or in advance a pocket pad The core member may be inserted through the inlet, and the inlet may be sealed.

However, in order to avoid the adhesion process of the pad member such as silicone rubber, a method of forming a patch in which the pad and the core member are combined by forming the pad member by inserting the core member in the mold in advance and inserting the insert may be considered. . Here too, depending on the temperature, the core member is bidirectionally deformed between the reduced type and the expanded type, and the pad member is also deformed according to the deformation of the core member, so that the function of spreading the wrinkles on the skin where the patch is attached.

8 and 9 are perspective and longitudinal cross-sectional views showing another embodiment of the present invention.

In the patch for improving wrinkle wrinkles using the shape memory alloy as shown in FIGS. 8 and 9, both ends of the shape memory alloy core member 200a are buried in the silicon pad 203 having a predetermined thickness, and the silicon pad 203. (Not shown) is applied to the bottom surface and the release paper 300 is attached to the adhesive.

8 and 9 is a patch for improving wrinkles using a single shape memory alloy. In order to enhance the tensile force due to the memory ability, a pressure is applied in the middle in the longitudinal direction of the formed memory alloy core member 200a One or more buffer portions 202 are formed by deformation, and the length of the core member is extended in proportion to the length of the core member when the core member returns to the circle due to body temperature.

The patch is attached to the skin so that the longitudinal direction is disposed in the perpendicular direction of the wrinkles can be useful for removing local wrinkles. In the drawings, reference numeral 202 denotes a buffer portion, 201 denotes curls bent at the end of the shape memory alloy, and 203 denotes a silicon pad.

The present invention has been described above by way of limited embodiments, which are only illustratively described to help understanding of the present invention, and the present invention is not limited to these specific embodiments. That is, one of ordinary skill in the art to which the present invention pertains may make various modifications or applications based on the present invention, and such modifications and applications belong to the appended claims.
