Description

Micro-needle roller {Micro-needle roller}

The present invention is a microneedle roller that forms micropores in the skin by pressing a plurality of microneedles having a fine size in a state connected to the skin surface, and stimulates the skin surface by the formation of the micropores to aid skin regeneration. About.

In the field of dermatological treatment or beauty, a procedure for promoting skin regeneration by stimulating the surface of the skin with a micro-needle is widely practiced, and a microneedle roller having a plurality of microneedles is used for this procedure.

The present invention relates to a micro needle roller, and more particularly, to a micro needle roller used for delivering cosmetics or drugs through skin tissue and healing skin tissue.

In general, the delivery of cosmetics or drugs through the skin is difficult to pass through the stratum corneum of the skin, so its absorption rate is very low. In particular, in the case of cosmetics or drugs having a large molecular weight, the absorption rate is further lowered. In order to improve this, a technique using microneedles has been proposed. This is a method of forming a new channel passing through a part or all of the epidermal layer using a microneedle, and delivering a drug to the epidermal layer or a lower layer thereof through the channel.

According to the above method, drugs having a large molecular weight, such as insulin and hormone preparations, can be easily delivered through the skin. In addition, when microneedles penetrate and stimulate the dermal layer, burns and scars are naturally healed. In addition, collagen production is induced, so that skin tone improvement and anti-aging effects can be maximized.

Currently, a microneedle roller is mainly used as a means for forming a channel by a microneedle. The microneedle roller has a structure in which the microneedles protrude from the surface of the roller head on a cylindrical roller head. As the roller head formed as described above is rotated, the microneedles form many channels in the skin at once.

The microneedle roller 100 of the present invention, A roller head 111 having a plurality of slots 117 formed on the outer circumferential surface as a cylindrical shape so as to cross the circumferential direction; A needle array base 123 inserted into the slot of the roller head 111; A needle array bar 121 formed integrally with the needle array base 123 and having a plurality of microneedles 125 formed to protrude from the outer circumferential surface of the roller head 111; A roller handle 141 having a roller head coupling portion 143 at a tip end portion so that the roller head 111 is rotatably coupled; UV LED lamp 250 provided on one side of the roller head coupling portion 143; And an ultrasonic generator 120 provided at the distal end of the roller head coupling part 143.

1 and 2 are perspective and exploded perspective views of a microneedle roller 100 according to an embodiment of the present invention.

1 and 2, the microneedle roller 100 of the present invention includes a roller head 111, a needle array bar 121, a side cover 131, and a roller handle 141. A plurality of needle array bars 121 are coupled to the roller head 111, side covers 131 are interposed on both sides of the roller head 11, and a roller handle 141 is coupled to one side thereof.

The roller head 111 has a cylindrical shape, and has a cartwheel-shaped cut cross section in which a fan-shaped through hole 119 is formed. As a result, the volume of the roller head 111 is reduced and the thermal effect is reduced, thereby preventing thermal deformation during the molding process.

Fitting protrusions 115 are formed on both sides of the roller head 111 in which a rotation shaft coupling groove 113 for coupling the roller handle 141 is formed at the center portion. The fitting protrusion 115 and the rotation shaft coupling groove 113 are provided for coupling and smooth rotation with the roller handle 141 and coupling with the side cover 131. In addition, it may have a variety of known coupling structures within a range that enables the roller head 111 to rotate while being coupled with the handle 41.

A plurality of slots 117 are formed on the outer circumferential surface of the roller head 111 in a direction transverse to the circumferential direction. In addition, a needle array bar 121 is fitted into the slot 117. The slot 117 may be formed in various shapes, but it is preferable that the upper portion has a narrower width than the lower portion. For example, it is preferable to form a concave-shaped slot 117 whose upper width is narrower than the lower width. Accordingly, it is possible to prevent separation of the needle array bar 121 from the roller head 111 during the rotation of the roller head 111.

The roller head 111 may be manufactured by injection molding a thermosetting resin or a thermoplastic resin. For example, it may be made of a thermoplastic resin such as PC (Polycarbonate), PEI (Polyetherimide), POM (Polyacetal), PMMA (Polymethylmethacrylate), PLA (Polylatide), PSU (Polysulfone). Alternatively, it may be manufactured by injection molding with a thermosetting resin such as an epoxy resin, a phenol resin, or a polyurethane resin.

The needle array bar 121 is divided into a needle array base 123 and a microneedle 125, and has a structure in which the microneedles 125 protrude from the surface of the needle array base 123. The needle array base 123 has a shape and size corresponding to the slot 117 of the roller head 111 so that it can be fitted into the slot 117 of the roller head 111.

The needle array base 123 and the microneedle 125 are integrally formed. The needle array bar 121, that is, the needle array base 123 and the microneedle 125 may be manufactured by injection molding a thermosetting resin or a thermoplastic resin.

The needle array bar 121 is made of a polymer resin by injection molding and press molding using a metal mold. In particular, the needle array bar 121 is preferably made of a material of a biodegradable polymer such as PLA (Polylactic acid) or PLGA (Poly lactic-co-glycolic acid). This is because when the microneedles 125 are separated from the needle array base 123 and remain in the skin, they are harmless to the human body and can be quickly disassembled.

The microneedle 125 protrudes from the outer peripheral surface of the roller head 111 to a predetermined height. That is, the protrusion height of the microneedle 125 may vary depending on the intended use. For example, when the microneedles 125 penetrate the epidermal layer to form a channel to reach the dermal layer, the protrusion height of the microneedles 125 is preferably 200 μm to 800 μm.

In order for the microneedles 125 to penetrate about 100 um to 400 um into the dermis of the skin, the protrusion height of the micro needles of the present invention is preferably 200 um to 800 um.

That is, since the penetration depth of the microneedles 125 into the skin is about half of the length of the microneedles 125, the microneedles of the present invention are used to penetrate about 100 um to 400 um into the dermis of the skin. It is preferable that the length is 200 um to 800 um

On the other hand, the microneedles 125 may form rows at uniform intervals in the needle array base 123. This makes it possible to form a uniform channel distribution over a specific area of the skin. It is preferable to make the gap between the needle array bars 121 in the roller head 111 as narrow as possible. This is because the microneedles 125 can form a large number of channels in the skin of a specific area.

The roller handle provided in the microneedle roller 100 of the present invention includes a U-shaped roller head coupling portion 143 and a handle portion 147 connected to the roller head coupling portion 143 as shown in FIG. Includes.

In addition, the roller head coupling portion 143 includes two clamp arms 144. In addition, each clamp arm 144 has a rotation shaft protrusion 145 so as to be used as a rotation axis of the roller head 111. Two rotation shaft protrusions 145 formed to face each other are coupled by being fitted into the rotation shaft coupling groove 113 of the fitting protrusion 115 of the roller head 111. The clamp arms 144 facing each other at the roller head coupling part 143 are configured to have a material or structure that allows them to be spread apart from each other. Accordingly, the roller head 111 and the roller handle 141 can be easily coupled and separated by opening the clamp arm 144. Here, the roller handle 141 may have various other shapes as long as it is a shape suitable for a user to handle while fixing and rotating the roller head 111.

Disc-shaped side covers 131 are coupled to both sides of the roller head 111. The side cover 131 has an insertion hole 133 formed to be fitted into the fitting protrusion 115 of the roller head 111 at a central portion. The diameter of the side cover 131 is formed to have the same diameter as the cylindrical diameter of the roller head 111. The side cover 131 serves to support the needle array bar 121 so as not to be separated from the roller head 111. The diameter of the side cover 131 may have various shapes and sizes within a range that prevents separation of the needle array bar 11 without interfering with the performance of the microneedle 125. In addition, the side cover 131 may be attached to the side of the roller head 111 using an adhesive or may be fixed to the roller head 111 using a separate fixing member.

The micro-needle roller 100 of the present invention may include a driving motor 200 for rotationally driving the roller head 111 and an ultraviolet LED lamp 250 for sterilizing and disinfecting the roller head 111. .

In addition, it is preferable to additionally include a switch part 210 on one side of the handle part 147. That is, the switch unit 210 may control the supply of power to the driving motor 200 and the ultraviolet LED lamp 250. That is, when the switch unit 210 is operated, power is supplied to the driving motor 200 and the ultraviolet LED lamp 250, and accordingly, the roller head 111 rotates, thereby treating the skin. In addition, when the switch unit 210 is operated, the ultraviolet LED lamp 250 provided on the side opposite to the roller head 111 of the roller head coupling unit 143 emit light. While the ultraviolet LED lamp 250 emits light, the roller head 111 can be sterilized and disinfected.

Various types of known switches may be used as the switch unit 210 as described above. As for the above switches, a normal switch used to perform an operation to apply or cut off power to an electric device can be used, and among various types of known switches, a push button switch, a slide switch, or a touch switch, etc. may be used. I can.

In addition, it is preferable to provide an ultrasonic generator 120 at the distal end of the clamp arm 144 of the handle. The ultrasonic generator 120 is for increasing the transdermal permeability of the drug by using the ultrasonic waves by irradiating ultrasonic waves to the treatment area of the microneedle roller.

That is, the ultrasonic waves generated by the ultrasonic generator 120 have a great influence on the skin permeability of the drug in contact with the skin. Since the ultrasonic waves generated by the ultrasonic generator 120 can be transmitted through the skin of the human body, the drug is absorbed into the skin together with the ultrasonic waves. The ultrasound generated by the ultrasound generator 120 serves to help the drug that has touched the skin of the human body to be absorbed deeply into the skin, thereby increasing the degree of the drug injected into the human body.

By generating ultrasonic waves in the ultrasonic generator 120, a piezoelectric element can be used, and the piezoelectric element is a piezoelectric ceramic such as lead zirconium titanate (PZT), a composite piezoelectric element using these materials and polymer materials, or polyvinyl fluoride. It is possible to manufacture using a polymer material such as (PVDF).

At this time, in order to generate ultrasonic waves in the piezoelectric element, an electric signal is applied to the piezoelectric element, and mechanical vibration is generated by the piezoelectric effect of the piezoelectric element by the applied electric signal. Such a piezoelectric element is capable of generating ultrasonic waves of various frequencies, and by converting the frequency of an electric signal applied to the piezoelectric element, it is possible to change the frequency of mechanical vibrations generated in the piezoelectric element.

In addition, it is preferable to include a control unit 220 on one side of the handle unit 147. That is, the control unit 220 is a microprocessor that performs an overall control operation of the microneedle roller 100. When power is supplied from the power supply unit 230 by the switch unit 210, the control unit 220 controls the ultraviolet LED lamp 250, the driving motor 200, and the ultrasonic generator 120. That is, the control unit 220 is preferably provided to be selectively or simultaneously driven by controlling the driving motor 200, the ultraviolet LED lamp 250, and the ultrasonic generator 120.

That is, the controller 220 controls the light emission of the ultraviolet LED lamp 250 and also controls the ultrasonic radiation of the ultrasonic generator 120. Further, the control unit 220 controls the rotation of the roller head 111 by controlling the driving motor 200.

Ultraviolet sterilization can sterilize all bacteria, has the advantage of not giving resistance to bacteria irradiated with ultraviolet rays, and is simple and economical to use.

It is preferable that the number of the ultraviolet LED lamps 250 is set so that the total output can be adjusted according to the power of the ultraviolet rays to be output. The ultraviolet LED lamp 250 emits ultraviolet rays having a wavelength of 250 to 280 nm to sterilize the area exposed to the ultraviolet rays. AlGaN (aluminum gallium nitride) may be used as a source for emitting ultraviolet rays having a wavelength of 250 to 280 nm as described above.

In the microneedle roller 100 according to the present invention as described above, since the roller head 111 on which the micro needle 125 is formed can be automatically rotated by the driving motor 200, the circumferential surface of the roller head 111 It is in close contact with the skin, so it is easy to perform treatment on the correct area. In addition, since the sterilization effect by the ultraviolet LED lamp 250 provided in the roller head 111 is excellent, the skin regeneration effect is excellent because it can be repeatedly used without a separate killing or sterilization procedure. In addition, the ultrasonic waves emitted from the ultrasonic generator 120 serve to help the drug given to the skin of the human body to be absorbed deeply into the skin, thereby enhancing the transdermal permeability of the drug injected into the skin.
