Description

[0001] Drug injection device [0002]

The present invention relates to a drug infusion device, and more particularly, to a drug infusion device in which a drug stored in a drug tube is injected into the skin through a needle by pressure to press the drug tube.

In general, Meso Therapy was developed in 1952 by a French physician, Michel Pistor, as a treatment for injecting drugs or injecting stimuli into the dermal layer of the skin using microneedles.

The main purpose of mesotherapy is to treat obesity through fat decomposition, skin pain relief, hair regrowth, weight reduction, wrinkle removal, wound and acne treatment. The number of procedures has increased significantly.

The drug injector applied to the mesotherapy is a device for injecting the drug into the skin at a high speed using electricity or pneumatic pressure, which is also called "meso gun".

The meals are operated electrically or pneumatically, and are expensive products priced at thousands of dollars.

Driving these conditions requires the power to operate the syringe when inserting the needle into the skin and injecting a given amount of drug after insertion.

The pneumatic method is more preferable than the electric method because the temperature rise is small even when the continuous use is continued for a long time.

Korean Patent No. 10-0597814 discloses an example of such a pneumatic meso gun.

That is, the pneumatic drug main use gun of Patent No. 10-0597814 includes a gun body having a trigger for operation and a port for introducing air, and a syringe pressurizing cylinder And a catheter insertion cylinder mounted on a rod of a syringe pressurizing cylinder and pushing the syringe to push the syringe presser and a catheter insertion cylinder to move the catheter, A solenoid valve which is elongated from the inside to the outside so as to selectively intermit the air supplied to the catheter inserting cylinder from the movement of the catheter support, and a controller for controlling the operation of the solenoid valve in response to the operation signal of the ventilator.

The thus constructed pneumatic drug main gun is operated by a pneumatic operating mechanism, so that it can be used semi-permanently without heating even if it is used for a long time.

However, since the conventional pneumatic insertion gun is formed as a gun type in which a needle of a syringe is protruded to the outside, there is a problem in that it creates a feeling of rejection or fear of the patient with respect to the needle.

Therefore, the pneumatic drug gun generates a constant pressure in the regulator driving the cylinder for pressurizing the syringe, which generates pressure to inject the drug to adjust the amount of injected drug, and controls the operation time of the pressure generated for controlling the dose to be controlled electronically Unit (ECU) is used.

However, since the resistance pressure of the skin varies depending on the site of treatment when the drug is injected, when a small amount of drug is injected, the injected amount becomes inaccurate as the syringe receives the internal pressure of the skin, Further, there is a problem that the drug is not injected into the skin.
