Abstract
Provided is a sequential injection module included in a skin treatment device, the module sequentially injecting a gas and a drug into the skin of a user through one needle. The sequential injection module comprises: a supply port for supplying each of gas and a drug; an output port for discharging each of same; and a channel control part for forming, therein, either a gas flow channel or a drug flow channel by means of the pressure of the gas and drug to be supplied.
Claims15
A sequential injection module for injecting a gas and a drug into a skin of a user through one needle, the sequential injection module comprising:
- a gas input port being supplied with the gas into a first cavity therein;
- a drug input port being supplied with the drug into a second cavity therein;
- an output port discharging one of the gas and the drug to the needle through a third cavity therein;
- and
- a channel controller forming one of a gas flow path and a drug flow path while being moved horizontally by each of the gas and the drug between the first cavity, the second cavity, and the third cavity.
A skin treatment device for injecting a gas and a drug into a skin of a user through one needle, the skin treatment device comprising:
- a body including a discharge controller controlling discharge of a drug and a gas respectively from a drug container and a gas container accommodated therein;
- and
- a sequential injection module coupled between an end of the body and a holder to which the needle is coupled, and sequentially providing the drug and the gas supplied from the body to the needle,
- wherein the sequential injection module includes:
- a gas input port coupled to a gas outlet of the body and being supplied with the gas through a first cavity;
- a drug input port coupled to a drug outlet of the body and being supplied with the drug through a second cavity;
- an output port coupled to the holder and discharging one of the gas and the drug through a third cavity;
- and
- a channel controller forming one of a gas flow path and a drug flow path while being moved horizontally by each of the gas and the drug between the first cavity, the second cavity, and the third cavity.
