Description

Tip for drug injection, skin treatment device including the same, and skin treatment method using the same {TIP FOR INJECTING DRUG, SKIN TREATING DEVICE INCLUDING THE SAME AND SKIN TREATING METHOD USING THE SAME}

The present invention relates to a drug injection tip capable of injecting a drug into the skin, a skin treatment device including the same, and a skin treatment method using the same.

In general, a method of penetrating drugs into the skin is used as a treatment method for skin beauty and health, obesity treatment, etc., such as wrinkles, acne removal, exfoliation, hair loss treatment, etc.

Examples of these treatment methods include making a hole in the skin and applying medication or cosmetics on it to allow the drug to penetrate quickly and in large amounts to maximize the drug's effectiveness, and stimulating the skin with a needle and using the body's reflex action accordingly. There is a way to induce the formation of collagen.

When multiple microscopic holes are created in the human skin, new skin grows due to the self-renewal power of the damaged skin tissue, and when a therapeutic drug is applied to the area where the microscopic holes are formed, the drug can quickly penetrate into the skin through the microscopic holes.

In other words, the natural wound healing effect that occurs when multiple needles penetrate the skin causes the dermal tissue to be newly formed and rearranged, making scars shallower and the skin being pulled taut, reducing fine wrinkles and improving pigmentation, making it healthier. You can come back to clean skin.

However, if the drug is injected at high speed while the needle penetrates the skin, negative pressure is formed within the skin, preventing the drug from being supplied smoothly, and causing a strange feeling in the affected area.

Therefore, skin treatment devices that can smoothly inject drugs into the skin are being developed.

A drug injection tip, a skin treatment device, and a skin treatment method using the same according to an embodiment of the present invention are a drug injection tip that can smoothly inject a skin treatment drug into the skin, a skin treatment device, and a skin treatment method using the same. It's about treatment methods.

Figure 1 is a schematic cross-sectional view of a tip for drug injection according to a first embodiment of the present invention, and Figure 2 is an explanatory diagram of air movement of a tip for drug injection according to a first embodiment of the present invention.

The drug injection tip 100 according to the first embodiment of the present invention is replaceably mounted on the end of the handpiece 200 (see FIG. 5), and is used for needling, that is, by moving the needle to make a hole in the skin. This tip is used when injecting medication into skin that has already formed.

The drug injection tip 100 according to an embodiment of the present invention includes a tip case 110 and a cylinder 120.

The tip case 110 has a space formed inside it and the cylinder 120 is placed there. During the drug injection process, the tip case 110 is maintained in a fixed position in relation to the handpiece 200. That is, when the drug injection tip 100 is driven, the tip case 110 maintains a fixed position. Specifically, the tip case 110 is hollow in the vertical direction, and the cylinder 120 is placed in this space.

The cylinder 120 may be mounted with the handpiece 200 and be capable of reciprocating movement. As an example, the connecting rod 210 of the handpiece 200 may penetrate the top of the tip case 110 and be connected to the cylinder 120. At this time, a sealing member is interposed between the connecting rod 210 and the handpiece 200 to prevent air inside the tip case 110 from leaking between the connecting rod 210 and the handpiece 200.

A channel 121 through which the air inside the tip case 110 moves is formed in the center of the cylinder 120. A sealing member 122 is interposed between the outer surface of the cylinder 120 and the inner wall of the tip case 110, and the inside of the tip case 110 is divided into an external space A1 and an internal space A2 of the cylinder 120. . That is, air is discharged to the end of the tip case 110 as the cylinder 120 reciprocates. The inside of the tip case 110 is partitioned, and the air inside the cylinder 120, that is, the internal space A2, is discharged through the channel. It is discharged to the end of the tip case 110 through (121).

The internal space A2 of the tip case 110 may be divided into an upper first space A3 and a lower second space A4 based on the channel 121.

When the cylinder 120 moves forward (moving downward in the drawing), the volume of the first space A3 may increase and the volume of the second space A4 may decrease. Since the first space (A3) and the second space (A4) are communicated through the channel 121, the air in the second space (A4) can be moved to the first space (A3) through the channel 121. This is because the amount of change in the volume of the first space (A3) is greater than the amount of change in the volume of the second space (A4) due to the difference in cross-sectional areas between the first space (A3) and the second space (A4) in the drawing.

When the cylinder 120 retracts (moves upward in the drawing), the volume of the first space (A3) may decrease and the volume of the second space (A4) may increase, and thus the volume of the first space (A3) may decrease. The air may be moved to the second space (A4) through the channel 121. This is because the amount of change in the volume of the first space (A3) is greater than the amount of change in the volume of the second space (A4) due to the difference in cross-sectional area between the first space (A3) and the second space (A4).

A distribution plate 130 may be disposed at the end of the cylinder 120. The distribution plate 130 ensures that the air discharged from the end of the tip case 130 when the cylinder 120 is retracted has uniform pressure throughout. The distribution plate 130 is provided in a substantially plate shape and is placed at the end of the cylinder 120, and a plurality of through holes 131 are formed. As air is dispersed and discharged through the through hole 131, the pressure may be uniform throughout.

That is, since the air is discharged while the end of the tip case 110 is in contact with the needled skin, the area where the air is discharged is the area within the bottom of the tip case 110, and the air is discharged at a uniform pressure throughout the area. do. This allows uniform injection of the drug.

At this time, the distance between the distribution plate 130 and the end of the tip case 110 at the top dead center of the cylinder 120 may be about 10 mm.

Meanwhile, an air discharge hole 111 may be formed on the lower side of the tip case 110. As the cylinder 120 reciprocates, the discharge of air from the inside of the tip case 110 and the intake of air into the tip case 110 are repeated. The end of the tip case 110 is in close contact with the skin, and when the cylinder 120 advances, that is, when air moves from the second space A4 to the first space A3, it is applied to the skin and/or the skin. The drugs may be inhaled together.

Accordingly, an air discharge hole 111 is formed at the distal side, that is, the lower side, of the tip case 110, thereby preventing the skin and/or the drug applied to the skin from being inhaled when the cylinder 120 advances. .

In addition, since the reciprocation of the cylinder 120 is instantaneous, that is, for a very short period of time, even though the air discharge hole 111 is formed, when the cylinder 120 retracts, air is supplied to the skin and exerts pressure. I don't receive it.

Additionally, a through hole 112 may be formed in an area of the tip case 110 corresponding to the external space A1 of the cylinder 120. The through hole 112 allows the air in the space above when the cylinder 120 moves forward so that the cylinder 120 is not prevented from moving forward by the pressure caused by the air existing in the external space (A1) of the tip case 110. Resistance can be removed by leaking it to the outside.

Figure 3 is a schematic cross-sectional view of a tip for drug injection according to a second embodiment of the present invention.

The drug injection tip 800 according to the second embodiment of the present invention includes a tip case 110, a cylinder 120, and a splash prevention portion 810. Since the tip case 110 and the cylinder 120 are the same as those of the first embodiment, duplicate descriptions will be omitted.

When injecting a drug, the skin is in a needling state, so after applying pressure to the skin and injecting the drug, the tip case 110 must be separated from the skin to inject the drug in a different location, or the tip case 110 may be injected into the skin during the process of applying pressure to the skin. Blood may splatter between the tip case 110 and the tip case 110. The splash prevention unit 810 is configured to prevent blood, etc. from splashing out of the drug injection tip 800 during the drug injection process.

The splash prevention portion 810 is spaced apart from the outer surface of the tip case 110 to form a discharge passage 811. And an air discharge hole 812 communicating with the discharge passage 811 is formed in one area of the side. Additionally, the bottom of the splash prevention portion 810 is provided lower than the bottom of the tip case 110.

Therefore, when the drug injection tip 800 is brought into close contact with the skin, the lower end of the splash prevention portion 810 is in contact with the skin and the lower end of the tip case 110 is spaced apart from the skin. An air movement path is formed through the space between the bottom of the tip case 110 and the skin, the discharge passage 811, and the air discharge hole 812.

When the cylinder 120 retracts, the air in the first space (A3) moves to the second space (A4) through the channel 121, passes through the bottom of the tip case 110, applies pressure to the skin, and moves the air. Go to the path.

Due to the movement of air, the blood on the skin splashes toward the discharge passage 811, and thus gets on the inner surface of the splash prevention portion 810 or the outer surface of the tip case 110, preventing it from splashing out of the drug injection tip 800. do.

Figure 4 is a schematic cross-sectional view of a tip for drug injection according to a third embodiment of the present invention.

Optionally, a splash prevention unit 810 may be further included. Redundant description of the same configuration as the first and second embodiments will be omitted.

The needle holder 910 is configured to have a plurality of needles arranged therein. The needle holder 910 is detachably coupled to the cylinder 120.

Needle holder 910 is coupled to cylinder 120 through a mounting configuration. As an example, a protrusion may be formed on the back of the needle holder 910. The protrusion may be inserted into and fastened to the cylinder 120.

When the needle holder 910 is mounted on the cylinder 120, the needle holder 910 shields the lower end of the cylinder 120. That is, the needle holder 910 closes the lower surface of the cylinder 120 and prevents the air inside the cylinder 120 from moving to the outside.

The microneedle device according to this embodiment injects the drug after needling is completed in the treatment area.

Accordingly, in the case of needling, the needle holder 910 is mounted on the cylinder 120 and moves together when the cylinder 120 reciprocates, but prevents the air inside the cylinder 120 from being discharged to the bottom of the cylinder 120. While blocking, allow for needling on the skin.

Afterwards, when needling is completed, the needle holder 910 is separated from the cylinder 120 and the cylinder 120 is reciprocated to apply pressure to the skin so that the applied drug is injected.

The driving unit 300 may be controlled by the electronic control module 500. For example, the power module 400 that supplies power to the driver 300 may be controlled by the electronic control module 500.

The electronic control module 500 may be installed in the main body 700 equipped with a display module and an operation module 600.

The display module is manufactured in the form of a panel and can visually provide various information to the operator. As an example, the display module may display the operation mode in which the skin treatment device 1000 according to this embodiment is currently in progress. Additionally, the display module may display biometric information of deep skin tissue at the target point.

The electronic control module 500 is a component that electronically controls the components of the drug injection tip 100 according to the operator's manipulation. The driving cycle of the driving unit 300 may be controlled by the electronic control module 500. As a result, the reciprocating drive cycle of the piston portion 120 of the drug injection tip 100 can be controlled.

The electronic control module 500 and the driver 300/power module 400 may be connected to the electronic control module 500 through a cable. The driver 300/power module 400 is driven by receiving an input signal from the electronic control module 500.

The manipulation module 600 may be provided in the form of a button on the outer surface of the main body 700. The operator can turn the skin treatment device 1000 on/off or select an operation mode of the skin treatment device 1000 through the manipulation module 600.

Next, a skin treatment method according to the first embodiment of the present invention will be described.

Figure 6 is a flowchart of a skin treatment method according to the first embodiment of the present invention, Figure 7 is an explanatory diagram of the needling step of the skin treatment method according to the first embodiment of the present invention, and Figure 8 is a flowchart of the skin treatment method according to the first embodiment of the present invention. This is an explanatory diagram of the drug injection step of the skin treatment method according to one embodiment.

The skin treatment method (S1000) according to the first embodiment of the present invention includes a needle tip mounting step (S100), a needling step (S200), a drug injection tip mounting step (S300), and a drug injection step (S400). Includes. The drug injection tip of this embodiment is the drug injection tip of the first or second embodiments described above.

In the needle tip installation step (S100), the needle tip 10, on which a needle module to which a plurality of needles 11 are fixed, is mounted, is mounted on the end of the handpiece 200.

In the needling step (S200), the driving unit 300 of the handpiece 200 is operated through the manipulation module 600 to advance and retract the needle module.

As the connecting rod 210 of the handpiece 200 reciprocates, the needle module advances and retracts, and when the needle module advances, the needle 11 penetrates the skin and a hole is formed in the skin.

Once needling is completed on the skin, the medication is applied to the treatment area. This order may be changed.

That is, the drug can be applied to the treatment area before needling, or needling can be performed on the treatment area after applying the drug.

In the drug injection tip installation step (S300), the surgical tip 10 is separated from the handpiece 200, and the drug injection tip 100 according to an embodiment of the present invention is installed.

As the connecting rod 210 of the handpiece 200 moves reciprocally, the cylinder 120 advances and retreats.

At this time, when the cylinder 120 moves forward, the volume of the first space A3, which is the space above the channel 121 of the cylinder 120, increases, and the volume of the second space A4 decreases. Accordingly, the air in the second space (A4) is moved to the first space (A3) through the channel 121 of the cylinder 120.

At this time, the air existing in the external space A1 of the cylinder 120 flows out through the through hole 112, so that there is no resistance due to pressure when the cylinder 120 moves forward. In addition, the air discharge hole 111 prevents the drug applied to the skin from being inhaled into the cylinder 120.

When the cylinder 120 retracts, the volume of the first space A3, which is the space above the channel 121 of the cylinder 120, decreases and the volume of the second space A4 increases. Accordingly, the air in the first space (A3) is moved to the second space (A4) through the channel 121 of the cylinder 120.

As air is supplied to the needled skin and pressure is applied, the drug applied to the skin is injected into the skin through the hole formed in the skin.

The hole in the skin formed by needling is effective for about one hour, so even if the drug is injected after the entire treatment area is completely needled, there is no problem as the drug is all injected into the skin.

Next, a skin treatment method according to the second embodiment will be described.
