The present invention relates to a drug injection device, and more particularly, to a drug injection device of the mobile type to restore the skin layer evenly by injecting the drug appropriately while moving the needle after adsorbing the recessed or wrinkled skin layer.

In general, the best efforts to maintain beauty by removing the skin and wrinkles that have lost elasticity.

For example, surgical plastic surgery, a method of delivering high frequency energy to the skin, and a method of injecting a drug into the skin are widely known as skin regeneration methods for treating wrinkles or depressions on the skin.

The surgical plastic surgery method has a disadvantage in that fine scars are generated after surgery in a manner of cutting and pulling sutures of wrinkled or recessed skin tissue and expensive surgery.

In addition, the method of delivering high-frequency energy to the skin layer of the damaged skin is a method of surgically restoring the skin by applying high-frequency energy to the skin layer to securely bundle the collagen components and promote the generation of new collagen as the high-frequency energy is delivered. Compared to the conventional plastic surgery method, the cost is low, and there is no foreign object feeling compared to the method of injecting the drug, but the high energy is transmitted to the skin layer by using an electrode or a needle (NEDLE), and thus burns on the skin surface. There is a problem that can be accompanied.

In addition, the method of injecting the drug is widely used in the mesotherapy treatment method of injecting the drug directly into the mesoderm under the damaged skin with a syringe for skin regeneration, and more convenient and costly than the surgical plastic surgery method This is an inexpensive advantage, but there is a problem that the drug is not effectively injected between the epidermal layer and the dermis layer, the dermis layer or subcutaneous fat layer, the procedure cost is not very cheap in that the expensive drug is repeatedly injected every procedure.

In addition, most of the methods of injecting the drug to operate the piston of the syringe while rotating back and forth by the motor, gears for deceleration, the transfer screw and the transfer screw to supply the correct dose of the drug to the skin layer It is made to be injected through a needle inserted artificially into the skin layer. The drug injection method using the syringe is to inject the drug into the skin layer through a mechanical device, and the drug is injected only in the vicinity of the syringe needle penetrated, and the drug is repeatedly injected to move the syringe needle to the damaged peripheral skin layer. Because of the method, each time the needle is artificially inserted into the pain, and if the injection part is uneven, even recovery of the skin was very difficult. (See Patent Documents 1 to 5)

Therefore, the syringe moving means 4 advances the drug injection means 2, the base 3, and the syringe 100 mounted on the base 3 at the same time, inserting the needle 102 into the skin layer and removing the drug while injecting the drug. To perform the operation.

Next, the adsorption means 5, which is one of the core technologies of the present invention, protrudes by inhaling or vacuuming the skin in contact with the length of the treatment portion of the recessed or wrinkled skin layer. By maintaining the vacuum state so as to be attached, as shown in Figure 2 and 4 attached to the front end of the case 10, and the vacuum pump (6) in the vertical portion that is fitted and fixed to the fixing 51 The hose 61 connected to the T-shaped socket 52 is formed so that the needle 102 of the syringe 100 passes in the horizontal direction, and one side fitting portion 53 inserted into the socket 52 in the horizontal direction. ) Forms a through-hole 55 connected to the hose 61 while the sealing member 54 of the rubber material is coupled thereto, and the adsorption vessel 57 having a space 56 for sucking the skin on the other side thereof. It is done by

And the adsorption vessel (57) of the adsorption means (5) is formed of a transparent material, but the rubber ring (7) is coupled to both sides of the through hole (55) formed in the fitting portion (53), and the adsorption space (56) has a length While forming in an elongated shape, an exhaust groove 58 extending from the inner ceiling to the lower end is formed, and on the outside, a scale 59 and a needle 102 for identifying the vacuum-adsorbed height state of the skin can be identified. A scale 59 'identifying the distance (length) condition is indicated.

On the other hand, the rubber ring 7 fitted to the fitting portion 53 of the adsorption vessel 57 serves to seal the rotatable adsorption vessel 57 while maintaining the air to move to the hose (61).

In addition, the shape of the space portion 56 of the adsorption vessel 57 is formed in a long shape in the longitudinal direction so as to adsorb the skin in contact with the wrinkles, etc., the outer shape may be formed in a variety of shapes such as dome-shaped or square. In addition, the space length can also be provided in a large number of 5mm ~ 10mm interval size to select according to the treatment site, the height of the space 56 is also provided a large number of 2mm ~ 5mm interval size.

That is, the adsorption vessel 57 is to lift the vacuum by adsorption of the skin so that the needle 102 of the syringe 100 can be pinched more accurately between the epidermal layer and the dermis layer to be treated, the dermis layer or the subcutaneous fat layer, so that the shape of the container is skin Note that it can be made in various forms that are convenient to contact.

In addition, the exhaust groove 58 extending from the ceiling of the interior of the space 56 of the adsorption vessel 57 to the one side through-hole 55 and the lower end thereof has the skin blocking the opening of the through-hole 55 side or contacting the ceiling when vacuum is sucked. It will help to prevent the skin from swelling. Therefore, since the exhaust groove 58 smoothly flows the moving air for vacuum, the skin always swells evenly and serves to make the needle 102 convenient to plug in. On the contrary, the adsorption vessel 57 is injected after the drug injection. When separated from the first to lift the portion leading to the bottom air is easily introduced into the exhaust groove 58 can be conveniently separated.

Next, the operation of the drug injection device 1 of the present invention configured as described above will be described in detail in connection with the schematic block diagram devices of FIGS. 1 to 4 and 5.

First, while inserting the rear end of the needle 102 into the hook groove 31 of the base 3 while contacting the pressing portion 26 of the piston 101 of the syringe 100 filled with the drug as shown in FIG. 100 is stably seated on the base 3.

Subsequently, when the width and length of the skin to be injected are determined and the adsorption vessel 57 having a suitable size is coupled to the socket 52, the two rubbers coupled to the fitting portion 53 of the adsorption vessel 57 are determined. A through hole 55 formed between the rings 7 communicates with a hose 61 connected to the socket 52. That is, the space 56 of the adsorption vessel 57, the through-hole 55 and the hose 61 communicate with each other, and the adsorption vessel 57 is rotatable in order to contact the skin in a good state.

In addition, the state is a state in which power is supplied to the central processing unit 8 and the operation is started, the central processing unit 8 is the drug injection means in accordance with the operation of the first to third switches (81, 82, 83) It is a standby state for operating the 1st motor 21 of (2), the 2nd motor 41 of the syringe movement means 4, and the vacuum pump 6. As shown in FIG. The first to third switches 81, 82, and 83 may be mounted on the case 10 or attached in the form of a wired or wireless remote controller for easy operation after holding the case 10. The configuration is omitted.

Next, as shown in FIG. 4, when the adsorption vessel 57 of the adsorption means 5 is brought into contact with the skin requiring drug injection, first of all, the third switch 83 is operated to be controlled by the central processing unit 8. The vacuum pump 6 is operated, and the air in the adsorption vessel 57 is discharged through the through-hole 55 and the hose 61 by the operation of the vacuum pump 6, and then the epidermal layer, the dermis layer and the subcutaneous fat layer are adsorbed. It swells into the space 56 of the container 57 and becomes a vacuum state.

At this time, confirming that the skin layer suitable for the drug injection position swells into the space portion 56 of the adsorption vessel 57 while looking at the scale 59 and stops the operation of the third switch 83 when the proper state is reached. Will be maintained. The height of the scale 59 reaches either the skin layer or the subcutaneous fat layer between the epidermal and dermal layers selected to determine the location of drug injection.

Next, when the first switch 81 is operated, the second motor 41 of the syringe moving means 4 is rotated forward by the control of the central processing unit 8 to thereby rotate the second drive gear 42 and the second driven gear. Power is transmitted through the 43 to rotate the second transfer screw 44. At this time, the rotation of the second conveying screw 44 is changed to the positional movement of the second bushing 45 and leads to the movement of the vertical portion 32 of the base 3 to which the second bushing 45 is fixed. In addition, the movement of the vertical portion 32 of the base 3 soon moves together the first transfer screw 24 of the drug injection means 2 having one end fixed to the vertical portion 32.

Therefore, the operation of the syringe moving means 4 moves the syringe 100 for injecting the drug and the drug injection means 2 for injecting the drug filled in the syringe 100 into the skin layer at the same time, and vice versa. Reverse rotation of the second motor 41 of (4) moves the syringe 100 and the drug injection means 2 simultaneously in the reverse direction.

On the other hand, when the tip of the needle 102 of the syringe 100 seated on the base 3 by the operation of the syringe moving means 4 is advanced in the right direction as shown in Figs. 2 and 3a, the sealing member 54 is first opened. The needle 102 is inserted into the skin layer selected from the skin layer or the subcutaneous fat layer between the epidermal layer and the dermis layer which swelled in a vacuum while penetrating and then moving toward the adsorption container 57.

At this time, it can be seen that the epidermis is further inflated by the thickness of the needle 102 inserted into the skin layer, and the initial position of the drug is determined by judging the position by the scale 59 'of the adsorption vessel 57 and the first switch ( The operation of the syringe transfer means 4 is stopped at the same time as the operation 81 is stopped.

Next, when the second switch 82 is operated to inject the drug into the selected skin layer, the first motor 21 of the drug injection means 2 is driven, and the driving force of the first motor 21 is a first drive. When the first transfer screw 24 is rotated through the gear 22 and the first driven gear 23, the first bushing 25 fastened to the first transfer screw 24 moves to move the push rod 26 to the right. Direction, wherein the push rod 26 presses the piston 101 of the syringe 100 to introduce the drug into the skin layer through the needle 102.

If the first switch 81 is operated in reverse when the drug is injected into the skin layer by the operation of the drug injection means 2, the central processing unit 8 reversely rotates the second motor 41 of the syringe moving means 4. And the power of the needle 102 of the syringe 100 finally seated on the base 3 via the second drive gear 42, the second driven gear 43, and the second transfer screw 44. Is moved to the left, which injects the drug while moving in the longitudinal direction of the recessed or corrugated portion.

In the above process, the prescribed amount of drug injection is precisely injected into the skin layer at the same time as the movement of the needle 102, thereby enabling a very stable and even restoration of the skin.
