Korean Patent Registration No. 10-1066883 (current injection type multi-injection needle and automatic injection device) is known as such a conventional technique, in which a high frequency is directly applied to a treatment site by a multi-injection needle to activate a cell or a blood vessel Discloses a technique for promoting activation of skin cell tissue by injecting the following drug to enhance the drug treatment effect.

However, in the case of the first conventional technique, since the drug is forcedly injected without skin extension, the skin is severely acrid, the consumption of the drug is large, and the treatment cost is high, It is practically impossible to form a part for generating a current.

In addition, in the case of the second prior art, since the first electrode and the second electrode are formed by joining the left and right electrodes around the insulator in order to apply a current, assembly and manufacturing are cumbersome as the number of component parts increases. There is a fundamental problem that the manufacturing cost rises.

According to the present embodiment, the UVLED (ultraviolet light emitting diode) is turned on to output blue light including ultraviolet rays. More specifically, the UVLED is outputted toward the outwardly projecting needle 200, The blue light passing through the needle guider 113 is irradiated to the skin surface of the subject to be naturally sterilized and sterilized, so that it is not necessary for the operator to wipe the surface of the skin by alcohol disinfection or the like beforehand, which is advantageous in the procedure.

Further, since the blue light including ultraviolet rays emitted from the UVLED (ultraviolet light emitting diode) is naturally sterilized and sterilized together with the needle 200 during the process of passing through the needle through hole 113a of the needle guider 113, 200) is basically unnecessary. Therefore, even if the needle 200 is exposed to the atmosphere, the risk of infection can be greatly reduced, so that it is possible to provide an opportunity to use it more safely in terms of hygiene.

Next, the automatic scanning device according to the present invention will be described, and the description of the abnormal current application type module, which is not addition of a new configuration, is replaced with the above description.

The current application type needle module A is fixed to the engagement protrusion 660 through the engagement protrusion 151 of the clip 150 so that the current application type needle module A is separated upward Therefore, there is an advantage that the fixability is further improved.

The current-applying needle module A further includes a suction hole 160 and a suction hole 670 corresponding to the suction hole.

Here, the suction port 160 functions to suck the skin through the formation of negative pressure, and the suction hole 670 of the suction condition (B) has a function of sucking air into the suction port 160 to generate a negative pressure .

The suction port 160 includes a suction protrusion 161 extending from one surface (see FIG. 5) of the body 110 to surround the plurality of needles 200 of the current application type needle module A, (Not shown) extending from the lower surface (see Fig. 5) of the suction hole 610 and being removably fitted in the suction hole 670, one end of which is communicated with the inside of the suction projection 161 and the other end is connected to the suction hole 670 .

The hose of the negative pressure generating body is connected to the suction hole 670 and the negative pressure generating body (for example, a vacuum pump) may be provided within the sealing condition B or may be provided outside the sealing condition B, .

According to the present embodiment, since the skin is sucked inward through the suction hole 160 and the suction hole 670 through the negative pressure, the needle 200 can be easily inserted into the skin.

Further, since the connection pipe 162 of the suction port 160 is press-fitted into the suction hole 670 of the bushing condition B, the stability between the current-applying needle module A and the bushing condition B can be further improved You can also expect to see some side effects.

On the other hand, in the above-mentioned condition (B), a plurality of display light sources 680 are formed in the longitudinal direction (see FIG. 8A) and function to visually display the intensity or operation state of the suction force.

In this embodiment, a light emitting diode (LED) is applied to the display light source 680.

As an example, ten display light sources 680 are applied in this embodiment, and the intensity of the suction force can be visually confirmed according to the number of lighted lights, and in another example, the light is sequentially turned on by the operation switch D The operation state can be visually confirmed.

Hereinafter, the operation of the present invention will be described.

First, the syringe S and the current application type needle module A are respectively inserted into the syringe holder F and the needle module holder 640 provided on the upper surface of the bare condition B to fix them, The cover 500 is detached from the body 110 of the module A.

When the current application type needle module A is pressed downward in a state in which the clip 150 of the current application type needle module A is placed in the engagement protrusion 660 of the condition B, A clip 150 formed on the outer surface of the body 110 of the applied needle module A is fixed to the latching jaw 660 as it is widened to the left and right while the terminal 320 of the current- And the connection pipe 162 of the suction port 160 of the current application type needle module A is inserted into the suction hole 670 of the condition (B) while being electrically connected to the connection terminal 650 of the condition (B) , The assembly is completed.

Then, in the menu window 920 of the controller E provided in the above-mentioned condition (B), an input button 910 is used to select a mode suitable for the purpose of use.

Next, when the needle 200 of the current-applying needle module A is pushed into the skin of the subject and the operation button 620 of the massage condition B is pressed, the operation button 620 is operated A switch D is connected so that the motor 710 of the pressing means C operates in accordance with the program set in the controller E and a current flows through the terminal 650 of the PCB 300 And the supplied current is again transmitted to each of the needles 200.

As the motor 710 is operated, the feed screw 720 fixed to the motor 710 rotates so that the piston holder 730 moves along the feed screw 720 while moving the piston S- And the injected fluid injected into the injector S as the piston S-1 is pressed is injected into the skin of the subject through the needle 200 of the current-fed needle module A .

In addition, in the case of the needle 200 inserted into the skin, the current flowing through the needle 200 massages only the fine operation site without damaging the skin tissue, activating the tissue and cells, and expanding the blood vessel, , Minimizes painfulness, reduces discomfort, improves the absorbency of the injected drug, and creates an environment in which the efficacy of the drug is improved.

In addition, since the skin is naturally sucked and drawn into the suction protrusion 161 where the needle 200 is disposed by the suction port 160 and the suction hole 670, the needle 200 can be easily inserted into the skin Particularly the portion of the needle 200 that does not touch the surface due to bending (facial), attracts the skin with the suction force, and the needle 200 can be inserted into the skin.

Further, the light source 400 is also operated by the operation switch D or the controller E. More specifically, the UVLED (ultraviolet light emitting diode) constituting the light source 400 is operated by an operation switch D or the controller E and outputs blue light including ultraviolet rays toward the needle 200. The output blue light is irradiated to the skin surface of the subject to be sterilized and sterilized.

Then, the injection fluid may be injected into the skin of the subject to be treated while moving the position as described above.

According to this embodiment, since the needles 200 provided on the needle body 100 can be connected to each other through the single PCB 300, it is possible to exhibit performance similar to that of the conventional art, The number of contrast components is simplified, the ease of assembly and manufacturing is further improved, and the manufacturing cost is remarkably reduced.

According to the present embodiment, when current is supplied to the needle 200 through the PCB 300 while the needle 200 is inserted into the skin, the current flowing through the needle 200 is transmitted to the needle 200 through the PCB 300, Massage of the treatment area only activates tissues and cells and expands the blood vessels. Therefore, it is possible to quickly infiltrate the drug into the skin, minimize pain and minimize discomfort, improve the absorbability of the injected drug It is quite useful because it can create an environment that allows the drug to be effective quickly.

According to the present embodiment, the UVLED (ultraviolet light emitting diode) constituting the light source 400 is illuminated by the operation switch D or the controller E and the needle 200 projecting blue light including ultraviolet rays And the output of the blue light is irradiated to the surface of the skin of the patient to be treated, the surface of the skin is sterilized and sterilized naturally, so that the operator does not need to wipe the surface of the skin with alcohol disinfection or the like beforehand, .

In addition, since the blue light including the ultraviolet rays emitted from the UVLED (ultraviolet light emitting diode) naturally sterilizes and sterilizes the needle 200 together, the disinfection of the needle 200 is basically unnecessary, Even if exposed to the atmosphere, the risk of infection is low, so it can be used safely in terms of hygiene.

Further, since the skin is naturally sucked and drawn into the suction protrusion 161 where the needle 200 is disposed by the suction port 160 and the suction hole 670, the needle 200 can be easily inserted into the skin Particularly, since the needle 200 can be inserted into the skin by attracting the skin by the suction force even in the portion where the needle 200 does not touch due to the bending of the face (facial), the procedure is advantageously convenient regardless of the shape of the face.

Further, since the syringe holder F corresponding to the diameter of the syringe S is used in combination with the mandrel B, the deformation and breakage ratio of the syringe holder F due to repeated use can be drastically reduced, In particular, since the mech- anism (B) and the syringe holder (F) are mutually coupled / detachable, there is an advantage in that replacement cost can be greatly reduced since only the corresponding parts need to be replaced.
