Description

[0001] The present invention relates to an auto-injection system with a cooler hand piece,

The present invention relates to an autoinjection system for automatically activating a syringe for injecting an injectable material into the skin for skin care or treatment, and more particularly, And a cooler handpiece which is used to control skin irritation or to soothe skin after the procedure is completed.

It is very common to inject vitality formulations and fillers. Usually, the bioactive agent and the filler are injected by hand using a conventional syringe of the type in which the plunger is manually reciprocating, i.e., a hypodermic syringe, with respect to a body having a neck on which the needle is inserted, do. However, since the syringe is designed to be ergonomically disadvantageous, there are many inconveniences in use. In addition, the conventional manual scanning method using a cylinder has a serious disadvantage that it is difficult to control the scanning speed and the handling of the syringe because of the need of the human force to push the injection material into the subject or the patient's body . In addition, in the conventional manual scanning method, there is a great possibility that a practitioner uses a syringe to apply a force in an excessive and unwanted direction in a process of pushing the injection material into a human body, thereby causing a great pain to the subject.

On the other hand, various types of syringe-operated injectors have been proposed, which are capable of automatically injecting injected materials using motor power for a fixed amount of scanning and precisely controlled scanning speed. For example, in Korean Patent No. 10-1526474, when a suction needle member is brought into close contact with skin by vacuum suction force, an injection needle of a suction needle member connected to a syringe is inserted into the skin, and a certain amount of drug is supplied to the skin When the injection is performed, the driving of the vacuum pump is turned off to remove the vacuum suction force, thereby making it possible to separate the suction needle member from the skin. In such a technique, the vacuum suction force is measured by a pressure sensor provided on the air suction pipe in the main body, and the vacuum suction force is controlled based on the measured pressure.

Although the automatic injection system using the injector for syringe operation has many merits, there is still a problem that the operator experiences the pain during insertion of the injection needle into the skin. In addition, there were many difficulties in calming the skin after completion of the procedure.
