Description

Drug injection device and driving method thereof

The present invention relates to a technology for reusing a drug in a device for injecting a drug into the skin in a spraying manner, and more particularly, a drug injection device that is sprayed onto the skin and recovers the remaining drug that is not injected into the skin and can be reused and to a driving method thereof.

Recently, interest in skin care is increasing, and it is reported that skin care is deeply related to wrinkle treatment. Conventional wrinkle treatment was possible only on a part of the skin, but recently, treatment equipment that can straighten fine wrinkles on the cheeks, backs of hands and necks has been developed. Such treatment equipment directly injects hyaluronic acid into the skin like filler therapy, so the effect appears immediately after the procedure. In particular, patients undergoing filler therapy do not need special preparation and can return to daily life quickly with a short treatment time of about 20 minutes, so they are receiving high attention from people who do not have time.

The conventional filler therapy for skin care is to inject drugs by hand using a hypodermic syringe having a manual plunger. Therefore, when using such a filler therapy, it is difficult to inject an appropriate amount of a drug (eg, a skin nutrient) into the skin, and there is a problem in that it is difficult to control the injection speed. Moreover, there is a problem that the recipient feels pain.

Recently, a drug injection device has been developed that injects a drug into the skin (eg, the dermal layer) through pores or pores by spraying the drug onto the skin without using a syringe.

1 is a block diagram of a drug injection device according to the prior art.

Referring to FIG. 1 , a drug injection device 100 according to the prior art includes a supply container 110 in which a drug to be sprayed to the skin is stored, and a recovery container in which the recovered drug is stored without being injected into the skin after being sprayed on the skin ( 120), the supply pump (P11) for pumping the drug stored in the supply tube 110 to the skin side and the drug recovered without being injected into the skin after being sprayed on the skin to the recovery tube 120 side It includes a handpiece 130 having a recovery pump P12 and a spraying tube 140 having a spraying nozzle to spray the drug supplied from the handpiece 130 to the skin.

The handpiece 130 drives the supply pump P11 and the recovery pump P12 according to the user's request. At this time, the injection pipe 130 is rotated in a clockwise or counterclockwise direction by the handpiece 130, and is reciprocated by the user.

In this state, the drug (vitamin or skin nutrient) stored in the supply tube 110 is sprayed onto the skin through the injection nozzle formed in the supply pipe 111, the supply pump P11, and the injection pipe 140, and some of the skin is injected inside. At this time, the user grips the handpiece 130 and moves in a zigzag manner as if scanning a skin area (eg, face) to be cared for while the injection tube 140 is in contact with the skin.

At this time, the drug that is not injected into the skin after being sprayed on the skin remains on the skin, which is recovered through the recovery pipe 121 and the recovery pump P12 and stored in the recovery container 120 .

However, when the drug is injected into the pores or pores of the skin using the drug injection device according to the prior art, there are much more drugs that are not injected than the drugs injected into the skin due to the nature of the injection method through the holes.

The type of each of the valves V21 to V23 is not particularly limited, and various types of valves may be used. For example, the valves V21-V23 may be implemented as solenoid valves.

The supply tube 210 is a container in which the drug to be sprayed on the skin is stored. The component of the drug is not particularly limited, and may include a therapeutic drug containing a component for the treatment of skin, or water to which a vitamin or skin nutrient is added for supplying nutrition to the skin.

The recovery container 220 is a container in which the drug, which is stored in the supply container 210 and then is sprayed onto the skin as many times as necessary through the injection tube 240, is recovered and stored.

The handpiece 230 controls the operation of supplying the drug stored in the supply barrel 210 so that it can be sprayed onto the skin as many times as necessary through the injection tube 240 and the operation of the circulation mode circulating for reuse, and It serves to control so that the drug, which is sprayed as many times as necessary, is no longer used, is recovered and stored in the recovery container 220 . Here, the 'circulation mode' may be referred to as a 'feedback mode'. To this end, the handpiece 230 includes a supply pump (P21), a circulation pump (P22), a recovery pump (P23), a supply valve (V21), a circulation valve (V22), a recovery valve (V23), and a control unit (231). can do.

The supply pump P21 serves to pump the drug to the injection tube 240 through the supply pipe 211 so that the drug stored in the supply tube 210 can be injected to the skin through the injection pipe 240 . The circulation pump (P22) serves to pump the drug to the supply tube 220 side through the circulation pipe 212 so that the drug that is not injected into the skin can be reused after being sprayed on the skin.

The injection tube 240 serves to inject the drug supplied through the handpiece 230 to the skin while being rotated by the handpiece 230 . To this end, the injection pipe 240 is a pair of injection nozzles ( 243A, 243B) may be provided.

The push rod 242 serves to expand the pores 601 or pores by pressing the skin on the area where the drug is to be sprayed. Therefore, when the drug is injected into the skin using the push rod 242, the skin injection rate of the drug can be improved. However, the pressing rod 242 may be omitted if necessary.

In general, the size of the human pores 601 is about 1/50 of that of a hair as shown in (a) of FIG. 6A. However, when the other end of the pressing rod 242 is lightly pressed while in contact with the skin as described above, the skin is depressed and stretched, and the pores 601 located around the pressing rod 242 expand as shown in FIG. 6a (b). Therefore, the drug can be injected more easily.

For reference, in the description of the present invention, sweat pores are not necessarily interpreted as being limited to sweat glands, but need to be understood to include all of the various routes through which a solution such as a drug is injected into the skin through pores or between the skin. there is. For example, it refers to all routes into which the solution can be injected, such as P1 to P4 in FIG. 6B . In technical terms, the sweat glands and pores are called the transappendageal duct, and the path through this is called the transappendageal route, and the path of solution movement through empty spaces such as between cell tissues is trans This is called the epidermal route. In FIG. 6B , a first path (P1) refers to a path passing between cells, a second path (P2) refers to a path through cells in the transverse direction, and a third path (P3) refers to a path passing through the sweat glands. means a path, and the fourth path (P4) refers to a path through the hair follicle.

Some of the drugs injected in this way are injected into the dermal layer through the pores 601 or pores of the skin. The drug injected into the skin by the injection nozzles 243A and 243B is injected instantaneously (eg, 200 m/sec) with a drug stem thinner than the thickness of hair, so that the recipient does not feel any pain.

As shown in FIG. 4 , the user holds the handpiece 230 by hand and proceeds in the injection mode or the recovery mode in a state in which the lower portion of the injection tube 240 is in close contact with the skin (eg, face) of the recipient. In this case, the user may set the operation mode of the drug injection device 200 to the injection mode or to the recovery mode. The injection mode or the recovery mode may be set based on a signal input by the controller 231 from the outside through an interface (not shown in the drawing) or automatically set according to time based on a pre-stored program. The recovery mode may be referred to as a simple supply mode. The operation of the injection mode and the recovery mode will be described as follows.

In the injection mode, the supply pump P21 and the circulation pump P22 are driven under the control of the controller 231 , and the driving of the recovery pump P23 is stopped. Then, the supply valve V21 and the circulation valve V22 are opened by the control signals CTL1 and CTL2 output from the control unit 231 , and the recovery valve V23 is closed by the control signal CTL3 . . Then, the injection pipe 240 is rotated clockwise or in the opposite direction by the control unit 231 .

And, the drug supplied to the injection tube 240 through the above path is injected into the skin through a pair of injection nozzles 243A and 243B. At this time, the injection tube 240 is not maintained in a fixed state, but travels in a zigzag manner as if scanning a skin area (eg, face) to be cared for by the user.

Some of the drugs injected into the skin are injected inside the skin and the rest remain on the surface of the skin. However, as described above, the drug remaining on the skin is sucked through the first suction port (not shown in the drawing) formed on the inner wall 241 of the injection pipe 240 by the driving of the circulation pump P22, and inhaled in this way The drug is returned to the supply tube 210 through the circulation pipe 212 and the circulation valve (V22).

The injection mode in which injection and circulation of the drug are performed simultaneously as described above may be continued for a time manually set by the user through a user interface, or may be continued for a time preset by the control unit 231 . As another example, the control unit 231 may check the turbidity of the drug through the turbidity sensor to continue the injection mode until the turbidity reaches a certain value or more. The turbidity sensor may sense the turbidity of the drug using infrared rays. For reference, the controller 231 may change the operation mode of the drug injection device 200 to a recovery mode or a circulation mode based on the turbidity detection signal of the drug measured by the turbidity sensor.

In this case, the controller 231 may control the driving of the supply pump P21 to adjust the strength or amount of the drug injected into the skin through the injection nozzles 243A and 243B of the injection tube 240 .

When the injection mode is completed, the recovery mode for recovering the drug in the supply barrel 210 is performed. At this time, under the control of the controller 231 , the supply pump P21 and the recovery pump P23 are driven, and the driving of the circulation pump P22 is stopped. Then, the supply valve V21 and the recovery valve V23 are opened by the control signals CTL1 and CTL3 output from the control unit 231 , and the circulation valve V22 is closed by the control signal CTL2 . .

Therefore, from among the drugs injected into the skin through the supply pipe 211, the supply valve V21, and the injection nozzles 243A and 243B after being pumped from the supply tube 210, the drug that is not injected into the skin is recovered by the recovery pump ( P23), the drug is inhaled through the second inlet (not shown) formed on the inner wall 241 of the injection pipe 240, and the drug inhaled in this way is recovered through the recovery pipe 221 and the recovery valve V23. and is stored in the recovery container 220 .

When the recovery mode is performed for more than a predetermined time, all of the drugs stored in the supply container 210 are recovered to the recovery container 220 through the same path as above. Therefore, thereafter, after the new drug is filled in the supply tube 210, the injection mode or the recovery mode may be performed as described above.

The operation of the drug injection device 1100 will be described as follows.

The cleaning mode and the drug injection mode for the operation of the drug injection device 1100 are set based on a signal input by the control unit 1141 from the outside through an interface (not shown in the drawing) or automatically according to time based on a pre-stored program can be set to

In the cleaning mode, the cleaning liquid supply pump (P111) and the recovery pump (P112) are driven under the control of the controller (1141), and the driving of the drug supply pump (P113) and the circulation pump (P114) is stopped.

Among the injected drugs, the drug that is not injected into the skin remains on the skin, which is pumped by the circulation pump P114 and recovered to the ampoule 1130 through the circulation tube and the circulation valve V113. Such a drug injection mode may be continued for a time manually set by the user through the user interface, or may be continued for a time preset by the controller 1141 . As another example, the control unit 1141 may check the turbidity of the drug through the turbidity sensor, and the injection mode may be continued until the turbidity reaches a certain value or more. The turbidity sensor may sense the turbidity of the drug using infrared rays. However, since the skin has been cleaned by the washing mode, the turbidity is maintained below a certain value until the drug stored in the ampoule 1130 is circulated and injected as described above and all injected into the skin.

When the fourth embodiment of Figure 15 is compared with the third embodiment of Figure 11, the second drug contained in the second ampoule 1532 is immediately applied to the skin after washing the skin with the skin cleaning solution stored in the supply tube 1510. There is a difference in that the second drug contained in the second ampoule 1532 is sprayed onto the skin after washing the pores of the skin with the first drug contained in the first ampoule 1531, rather than spraying it on the skin. As described above, the operation of the difference of cleaning the pores of the skin with the first drug contained in the first ampoule 1531 will be described as follows.

Even if the skin is washed with the skin cleaning solution stored in the supply tank 1510, foreign substances in the pores, for example, fat components, etc. are not completely cleaned. Therefore, as in the following description, foreign substances such as sweat pores are cleaned using the first drug contained in the first ampoule 1531 . The type of the first drug is not particularly limited. As an example of the first drug, a cleaning solution having a weak acidity (ph5.5) may be used. The type of the second drug is not particularly limited. As an example of the second drug, a vitamin agent or a skin nutrient agent may be used.

In the skin washing mode using the first ampoule 1531, the first drug supply pump P153 and the first circulation pump P154 are driven under the control of the controller 1541, and the remaining pumps P151, P152, P155, P156 ) is stopped. Then, the first circulation valve V153 is opened by the control signal CTL3 output from the control unit 1541, and the remaining valves V151, V152, and V154 are closed by the control signals CTL1, CTL2, CTL4. do.

Accordingly, the first drug stored in the first ampoule 1531 is pumped by the driving of the first drug supply pump P153 and is supplied to the injection pipe 1550 through the supply pipe 1511 . The first drug supplied in this way is injected into the skin through a pair of injection nozzles formed to face each other on the inner wall of the injection tube 1150 .

Foreign substances (eg, fat component) in the pores and the like are washed by the first drug sprayed in this way. After being sprayed with the foreign material, the first drug that remains injected into the pores or the like or remains on the surface of the skin is pumped by the first circulation pump (P154) and first through the first circulation pipe and the first circulation valve (V153). It is recovered as an ampoule (1531). Such a skin cleaning mode may be continued for a time manually set by the user through the user interface or for a time preset by the controller 1541 . As another example, the control unit 1541 may check the turbidity of the drug through the turbidity sensor, and the injection mode may be continued until the turbidity reaches a certain value or more. The turbidity sensor may sense the turbidity of the drug using infrared rays.

After the skin cleaning mode as described above is performed, the second drug spraying mode in which the second drug contained in the second ampoule 1532 is sprayed onto the skin may proceed.

As described above, when injecting a drug into the skin using the drug injection device according to the fourth embodiment of the present invention, the surface of the skin is cleaned using a cleaning solution, and foreign substances in the pores are cleaned using the first drug. Since the second drug contained in the second ampoule is circulated and injected into the skin in a re-spray method, more drugs can be injected into the skin, thereby reducing cost as well as improving treatment. .

As another embodiment, a larger number of ampoules may be added to the drug injection device 1500 of FIG. 15 , and the skin may be washed or injected into the skin with the drug in the ampoules through the same route.
