Description

Apparatus able to inject gas and drug into skin sequentially}

The present invention relates to a device capable of sequentially injecting gas and drugs into the skin, and more particularly, to a device used in mesotherapy procedures for removing skin wrinkles by sequentially injecting gas or air and drugs into the skin layer and subcutaneous layer. will be.

In general, mesotherapy, in which drugs are injected into the skin, is a kind of injection therapy, in which a small amount of therapeutic drug is injected into a skin layer and a subcutaneous layer by using a special syringe hole and a thin needle.

Mesotherapy is usually performed for diseases in the fields of acute and chronic pain, partial obesity and cosmetic surgery.

These mesotherapy procedures increase blood circulation and lymph circulation at the site of drug injection, eliminating various pains, partial obesity, skin wrinkles and preventing skin aging, and their effects are immediate and treatments have little pain and side effects. For example, it is a trend that is widely practiced.

For example, the mesotherapy procedure has the advantage of minimizing the overall hypersensitivity reactions and side effects caused by the drug and treating only the desired area by injecting a small amount of the drug into the subcutaneous tissue to be treated. Therapy is widely used in the treatment of beauty and diseases, such as obesity treatment, pain relief treatment, skin elasticity and scar improvement, and is also used for the treatment of alopecia by drug therapy.

Such mesotherapy methods include meso guns and manual ones. Meso guns have the advantage of adjusting the length of the needle depending on the site of the procedure. Due to the nature of the gun, there is a problem that delicate procedures are difficult when performing on sensitive areas such as a possibility of a medical accident when malfunctioning.However, the method of manual treatment is somewhat inefficient compared to the method using meso guns. It has the advantage of being able to perform delicate and precise procedures on specific areas that require treatment.

1 is a schematic view showing a general method of mesotherapy by hand.

As shown in FIG. 1, the operator directly plugs into the skin layer 110 while holding the needle 100 by hand, and then injects the therapeutic drug injected through the needle 100 into the skin layer 110. As the procedure is performed, the skin wrinkles 120 can be stretched by the therapeutic drug injected into the skin layer 110.

Here, reference numeral 130 denotes a subcutaneous layer.

However, the conventional mesotherapy treatment is inefficient in terms of treatment effects because it is a method of injecting only the drug into the treatment site.

For example, in the case of injecting only the drug into the site, there is a problem in that the drug is not effectively injected between the skin layer and the subcutaneous layer due to depression of the skin layer in the case of skin damage, particularly, wrinkles of the site.

Accordingly, the present invention has been made in view of the above, and when the mesotherapies injecting the therapeutic drug into the skin layer and the subcutaneous layer, the drug is injected in a state in which gas or air is put in the treatment site and the space is separated. By implementing a new gas (or air) and drug sequential injection system, it is possible to efficiently inject drugs between the skin layer and the subcutaneous layer, so that the gas and drug can be sequentially injected into the skin for accurate and stable treatment. The purpose is to provide a surgical device.

In addition, another object of the present invention is to provide a residual amount of the gas, air, or drug by intermittently intermittent with the injection of gas or air and drugs to intermittent the tube that is the gas, air or drug injection passage, The present invention provides a surgical device capable of sequentially injecting gas and drugs into the skin, which can effectively prevent the contamination of the surroundings due to drugs, the problem of leaking expensive drugs, and the like.

In order to achieve the above object, a device for injecting gas and drugs sequentially in the skin provided by the present invention is arranged side by side while injecting a needle for injecting drugs and gas (or air), respectively, supplied through each of the rear tubes. And a catheter having a gas / air injection needle, a means for automatically supplying drugs and gas (or air) through a tube to the catheter side, the syringe having a tube connected to the discharge port, and a plunger of the syringe The main body consists of a structure including an injection unit consisting of an actuator. The gas (or air) is injected into the skin layer by sequentially injecting gas (or air) and drugs using two needles of the catheter. It is characterized by the ability to inject drugs in the state of securing a space to separate.

Here, the surgical device capable of sequentially injecting gas and drugs into the skin includes two sets of syringes and actuators for injecting the unit for gas (or air) injection and for drug injection. It is desirable to be able to inject each sequentially.

As another example, a device capable of sequentially injecting gas and drugs into the skin includes a set of syringes and actuators for injection of the injection unit having a use for drug injection, and a gas (or air) injection for high pressure gas / It may also be desirable to have an air reservoir so that the gas (or air) and the drug can be sequentially injected respectively.

In addition, the surgical device capable of sequentially injecting gas and drugs into the skin is a residual amount preventing cylinder disposed on one side of a tube connecting the syringe and the catheter, and is mounted on a rod of the remaining amount preventing cylinder to prevent the remaining amount from being able to close or release the tube. It includes a residual amount protector composed of a residual amount prevention bracket which is disposed opposite the residual amount prevention rod with the rod and the tube interposed therebetween, and effectively controls the tube that becomes the gas, air, or drug injection path. There is a characteristic that can prevent contamination due to or waste of expensive drugs.

The apparatus for sequentially injecting gas and drugs into the skin provided by the present invention is a sequential injecting method, which firstly puts gas or air into the skin layer to separate the layers, and adopts a method of injecting drugs in such a state as to secure a space. By doing so, the drug can be effectively injected between the skin layer and the subcutaneous layer, and thus, there is an advantage in that a stable and efficient mesotherapy procedure can be performed along with the correct procedure.

In addition, the present invention provides a syringe needle by applying a residual amount preventer that selectively intercepts the drug or gas (or air) in the tube while operating in conjunction with the injection of the drug or gas (or air) for the mesotherapy procedure. Through the drug leaking through the surroundings can be contaminated, there is an advantage that can prevent expensive drugs from leaking.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below.

Shapes and the like of the elements in the drawings may be exaggerated to highlight more clearly described. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

Figure 2a and 2b is a perspective view showing a device capable of sequentially injecting gas and drugs in the skin according to an embodiment of the present invention.

As shown in Figures 2a and 2b, the surgical device capable of sequentially injecting gas and drugs into the skin is pre-injected air or gas into the treatment site before injecting the drug into the treatment site, and the injected air is depressed with gas. Lifting the skin layer to separate the skin layer and the subcutaneous layer is made by injecting drugs while securing a space.

To this end, two injection needles for injecting air, gas and drug, respectively, that is, injection needles 11 for injection and gas / air injection needles 12, are provided. Are mounted side by side on each other on the catheter (13).

Then, the respective tubes 10a and 10b are connected to the back of the drug injection needle 11 and the gas / air injection needle 12 in the catheter 13, and thus, the tubes 10a and 10b are connected. Gas, air or drug supplied through 10b) can be injected through the respective needles.

Here, the injection needle 11 for injection of the catheter 13 and the injection needle 12 for gas / air injection are set within 10 mm of each other, and the gas / air injection needle 12 is produced. It is desirable to allow the drug coming through the injection needle 11 for injection in the space to be sufficiently filled.

Thus, the catheter 13 having two injection needles may be used in a manner that is directly inserted into the skin in a state in which the operator holds the hand.

In addition, an injection unit 18 is provided as a means for automatically supplying drugs and gas (or air) through the tubes 10a and 10b on the catheter 13 side, and the injection unit 18 at this time is a gas (or Air) or a syringe 15 capable of filling a drug and an injection unit 18 capable of operating the plunger 16 of the syringe 15 to discharge a drug or gas (or air) filled therein. .

Gas (or air) provided by the present invention and the method of sequentially injecting the drug can be largely made in two ways.

For example, one approach includes two sets of syringe 15 and actuator 17 for gas (or air) injection and syringe 15 and actuator 17 for drug injection, This may be done by sequentially injecting gas (or air) and drugs from the set, respectively.

Another way is to have a set of syringes 15 and actuators 17 for drug injection, as well as a high pressure gas / air reservoir 19 for gas (or air) injection. Thereby injecting gas (or air) from the high pressure gas / air reservoir 19 and subsequently injecting the drug from a set of syringes 15 and actuators 17, as described in detail below. Let's do it.

2A and 2B show a set of syringes 15 and actuators 17 for use in drug injection, but a set of syringes and actuators for use in gas (or air) injection although not shown. Of course, it is provided.

In order to install the syringe 15 and the actuator 17, a table 33 having a predetermined height is provided. The syringe 15 is provided above the table 33, and the actuator 17 is installed below.

The syringe 15 is installed in a shape that is accommodated in the syringe housing 26 installed on the table 33, the discharge port 14 of the front end and the plunger 16 of the rear end protrudes toward the front and the rear of the housing exterior, respectively. Is located.

Here, the tubes (10a, 10b) are connected to the discharge port 14 of the syringe 15, so that the drug (or gas or air) in the syringe 15 through the tube (10a, 10b) catheter 13 It can be sent to the side.

At this time, the syringe housing 26 is formed in the shape of a rectangular case with an open top, thereby allowing the syringe body to be accommodated and withdrawn in the up and down direction.

In particular, the rear end of the syringe housing 26 is provided with a groove (31a) can be fixed by inserting a flange portion at the rear end of the syringe body, whereby the syringe body flows during operation of the plunger 16 It can be fixed firmly without.

The actuator 17 is formed of a cylinder type actuator using pneumatic pressure, and is mounted on the cylinder 20 installed on the bottom surface of the table 33 using the cylinder bracket 37 and mounted on the rod of the cylinder 20. It is configured to include a holder 21.

At this time, the holder 21 is extended to the upper side of the table 33 and is coupled to the handle portion of the plunger 16 through the groove 31b, thereby operating the plunger 16 during operation of the cylinder 20 As the holder 21 is held back and forth, the drug (or gas or air) contained in the syringe 15 is discharged by the pressure of the plunger 16 and the catheter 13 is passed through the tubes 10a and 10b. It can be fed to the needle.

The injection unit 18 comprising such a syringe 15 and an actuator 17 may optionally be applied in two ways: manually replenishing the drug or gas (or air), or automatically filling it.

For example, the syringe 15 may be used by filling the drug or gas (or air) at that time, or may be automatically filled and used after exhausting the drug or gas (or air) in the syringe 15.

A three-way valve 24 is provided as a means for automatically filling the drug or gas (or air).

The three-way valve 24 is installed between the discharge port 14 of the syringe 15 and the tubes 10a, 10b, the gas from the outside through the selective flow path of the three-way valve 24 Or air) and drugs to replenish.

For example, when the plunger 16 of the syringe 15 is pulled, drug, atmospheric air, and gas enter through the tube 10c only at the inlet of the three-way valve 24, and the plunger of the syringe 15 When pushing 16, the inlet is closed and only the outlet is opened. At this time, the drug, air or gas filled in the syringe 15 exits.

At this time, the amount of the drug or gas (or air) out through the syringe 15 is controlled by the time of the cylinder control, it is possible to discharge a fine amount or a large amount.

In addition, the injection unit 18 includes a manner that can be automatically replenished after the gas (or air) or drug in the syringe 15 is exhausted.

For example, one side of the cylinder 20 is provided with sensors 25a and 25b mounted at the front and rear stroke limit positions of the piston, and exhaust the gas (or air) or drug in the syringe 15, or the syringe ( 15) When the gas (or air) or drug is filled in, the gas (or air) or drug can be automatically filled by the signals of the sensors 25a and 25b, and when the predetermined amount is filled, the cylinder ( 20) can stop the suction operation.

In particular, the present invention provides a residual amount preventer 30 as a means to prevent the residual amount of drug or gas (or air) remaining in the tubes 10a, 10b.

The residual amount preventer 30 is a means for controlling a tube serving as an injection passage of gas, air, or drug. Phosphorus residual amount prevention rod 28, and the residual amount prevention bracket 29, which is a means for supporting the opposite side when pressing the tubes (10a, 10b).

The residual amount preventing cylinder 27 is located at one side of the cylinder 20 for supplying or inhaling a drug or gas (or air) and is installed at the bottom of the table 33, and the remaining amount preventing rod 28 is used for preventing the remaining amount. It is mounted on the rod of the cylinder 27 and protrudes upward of the table 33 through the long hole 32 in the table 33, and the residual amount prevention bracket 29 is disposed between the tubes 10a and 10b. It is installed on the table 33 while being disposed opposite the residual amount preventing rod 28.

At this time, the tubes (10a, 10b) extending from the syringe 15 toward the catheter 13 is passed between the residual amount prevention rod 28 and the residual amount prevention bracket 29.

Accordingly, when the residual amount preventing cylinder 27 is operated after the drug or gas (or air) is injected, the remaining amount preventing rod 28 is advanced to move the remaining amount preventing bracket 29 together with the tubes 10a and 10b therebetween. Since it is pressed, it is possible to exclude the problem that the drug or the like remaining in the tubes (10a, 10b) leak.

Of course, the operation of restraining the tube (10a, 10b) at this time is made in conjunction with the operation of injecting drugs or gas (or air), for example, before the needle is inserted into the skin (10a, 10b) ) Can be opened, so there is no problem with drug infusion.

Therefore, the operation of the actuator in the cylinder-type in the surgical device capable of sequentially injecting gas and drugs into the skin according to an embodiment of the present invention configured as described above is as follows.

3A to 3C are cross-sectional views showing a cylinder-type actuator operating state in a device capable of sequentially injecting gas and drugs into the skin according to an embodiment of the present invention.

As shown in FIGS. 3A to 3C, when the operator directly holds the catheter 13 by hand and inserts the injection needle 11 and the gas / air injection needle 12 directly into the skin, the gas ( Or air) and drug injection.

For example, when the set of cylinders 20 is operated backward while the tubes 10a and 10b are opened by the operation of the residual amount preventing cylinder 27, the plunger ( 16 is advanced, with which gas (or air) in the syringe 15 is injected through the gas / air injection needle 12 of the catheter 13.

After the injection of the gas (or air), if the other set of cylinders 20 is operated backward in sequence, the plunger 16 of the syringe 15 is advanced by the holder 21, which together with the syringe 15 Drugs of the genus are injected through the injection needle (11) for drug injection of the catheter (13).

On the other hand, after exhausting the drug or gas (or air) of the syringe 15, the cylinder 20 is moved forward to pull the plunger 16 of the syringe 15 again, so in the syringe 15 Drug or gas (or air) flowing through the tube 10c of the way valve 24 is filled.

4A and 4B are perspective views illustrating a device capable of sequentially injecting gas and drugs into the skin according to another embodiment of the present invention.

As shown in Figs. 4A and 4B, a motor-type actuator is shown here as an actuator means for injecting drugs or gas (or air), and the structure or usage of the catheter 13, the shape of the cylinder 15, Since the operation and the like are the same as the above embodiment, a detailed description thereof will be omitted.

The actuator 17 is formed of a motor-type actuator using the power of the motor, and is supported by the front support block of the two front and rear support blocks 36 installed on the bottom of the table 33. And, screw shaft 23 which is installed across the two front and rear support blocks 36 and the screw transmission structure with the screw shaft 23 is coupled to push or pull the plunger 16 while moving back and forth It is configured to include a holder 21.

Two guide bars 35 are provided side by side to accurately guide the front and rear movement of the holder 21.

Therefore, as shown in Figures 5a to 5c, when the operator directly holds the catheter 13, the injection needle 11 and the gas / air injection needle 12 directly into the skin, The injection of gas (or air) and the injection of drug are performed sequentially.

For example, when a set of motors 22 are operated in a forward direction while the tubes 10a and 10b are opened by the operation of the residual amount prevention cylinder 27, the holder moves by screw transmission with the screw shaft 23. The plunger 16 of the syringe 15 is advanced by means of 21, whereby the gas (or air) in the syringe 15 is injected through the gas / air injection needle 12 of the catheter 13. do.

After the injection of the gas (or air), when another set of motors 22 are operated forward sequentially, the plunger 16 of the syringe 15 is advanced by the holder 21 as above, and the syringe ( 15) The drug in the genus is injected through the injection needle (11) of the catheter (13).

On the other hand, after exhausting the drug or gas (or air) of the syringe 15, the plunger 16 of the syringe 15 is again pulled out by the reverse operation of the motor 22, so that 3 in the syringe 15 Drug or gas (or air) entering through the tube 10c of the -way valve 24 is filled.

Figure 6 is a perspective view showing a surgical device capable of sequentially injecting gas and drugs in the skin according to another embodiment of the present invention.

As shown in FIG. 6, here an example is provided for supplying gas (or air) by means of a high pressure gas / air reservoir 19 rather than a cylinder and an actuator.

To this end, a set of syringes 15 and actuators 17 are provided for the purpose of drug injection, and a high pressure gas / air reservoir 19 is provided for the purpose of gas (or air) injection.

Then, one tube 10a extending from the syringe 15 side is connected to the injection needle 11 of the catheter 13 and another tube extending from the high pressure gas / air reservoir 19 ( 10b) is connected to the gas / air injection needle 12 of the catheter 13.

Accordingly, the gas (or air) provided from the high pressure gas / air reservoir 19 by the operation of a predetermined solenoid valve (not shown) can be injected into the skin through the gas / air injection needle 12 In turn, drugs provided from the set of syringes 15 and the actuators 17 may be injected into the skin through the injection needle 11 for drug injection.

Therefore, a method of sequentially injecting gas and drugs into the skin using a device capable of sequentially injecting gas and drugs into the skin configured as described above is as follows.

Figure 7 is a schematic diagram showing a treatment method using a surgical device capable of sequentially injecting gas and drugs into the skin according to the present invention.

As shown in FIG. 7, the operator directly inserts the injection needle 11 for injection into the skin layer 110 and the injection needle 12 for gas / air injection into the skin layer 110 while holding the catheter 13 by hand. When operating the operation means (not shown), such as a switch or a button of, the actuator means and the like from this is made to sequentially inject the gas (or air) and the drug.
