Description

AirJet Handpiece {AIRJET HANDPIECE}

The present invention relates to an air jet handpiece, and more particularly, to an air jet handpiece which is capable of instantaneously injecting drugs into the skin through pneumatic pressure for the removal or treatment of skin elasticity, wrinkles, scarring, stretch marks, The present invention relates to an apparatus for diffusing and spreading a drug, which is capable of minimizing pain and is configured not only to rapidly infiltrate the skin but also to easily mount the injection syringe of the drug.

In recent years, people have been interested in preserving the beauty of skin by protecting the skin from elasticity, removing wrinkles, and so on. This is a skin regeneration method that smoothes or relieves wrinkles and depressions on the skin. Surgical plastic surgery, a method of delivering high frequency energy to the skin, and a method of injecting drugs into the skin are widely known.

First, surgical plastic surgery is performed by suturing and pulling out the sagging or depressed skin tissue. However, in this case, there are disadvantages such as fine scarring after operation and high cost of operation.

Next, when the high-frequency energy is applied to the skin layer, high-frequency energy is transferred to the skin, and the collagen is tightly gathered on the skin layer and the new collagen is promoted, thereby restoring the skin This method is less costly than surgical plastic surgery and has the advantage of being free of foreign objects as compared with the method of injecting drugs. However, it uses a needle or NEDLE to deliver high energy to the skin layer There is a problem that an image or the like may accompany the surface of the skin.

In addition, the mesotherapy operation method in which the drug is injected through the needle in the damaged skin for skin rejuvenation such as skin elasticity and scarring and wrinkle improvement is advantageous in that it is simpler and less costly than the above surgical operation method, (Dermal layer) and subcutaneous layer (dermal layer) are not effectively injected because the skin layer is depressed when the skin is damaged, especially when the skin is wrinkled. In addition, since the expensive drug is injected every time the procedure is performed, And there is a disadvantage that a foreign body sensation due to the drug can be felt. Further, since the drug is injected into the skin through the needles, there is a problem that the patient feels pain during treatment.

5 to 7, the operation and operation / effect of the air jet handpiece according to the present invention will be described.

5, the drug is supplied to the injection path 121b of the injection nozzle 120 through the drug supply hose H2 in the injector 200, and the drug is supplied to the cylinder 410 through the pneumatic valve 300 ) To supply high-pressure air to the inside.

6, high pressure air is supplied into the cylinder 410, so that the cylinder head 420 is advanced by the air pressure, and at the same time, the cylinder shaft 430 is also advanced. The stepped portion of the cylinder shaft 430 is engaged with the engaging piece 540 of the actuating means to restrict the movement of the cylinder shaft 430 forward. At this time, high pressure air is continuously supplied into the cylinder 410 to press the rear of the cylinder head 420, and the spring 440 interposed in front of the cylinder head maintains the compressed state.

7, when the operation switch 131 is operated, the second solenoid valve 550 rotates the pivot shaft 520 to thereby engage the step 431 of the cylinder shaft with respect to the engaging piece 540 Release. Then, the cylinder shaft 430 is moved forward by pneumatic pressure to strike the rear of the injection nozzle 120. At this time, the drug located in the injection path 121b of the injection tube is sprayed to the outside of the injection tube 121 and is applied to the inside of the skin.

When the injection of the drug into the injection path 121b of the injection tube 121 is completed, the air inside the cylinder 410 is rapidly discharged through the rapid discharge valve 141 and the compressed spring 440, As the compression is released, the cylinder shaft 430 and the cylindrical head 420 are moved backward as shown in FIG. Then, the skin is treated by applying the drug to the skin while repeating the above-mentioned operation.
