Abstract: The present disclosure relates to a medical skin treatment device, comprising a control unit for controlling the operation of the skin treatment device, a power supply unit for supplying power to the medical skin treatment device, and a main body including a drug storage unit for storing a drug to be injected into the patient's skin, a transport unit for moving the main body, a handpiece that receives power from the power supply unit of the main body, is controlled by the control unit, and injects the drug into the patient's skin to improve the skin, and a ring-shaped transducer that vibrates at a predetermined treatment frequency to deliver vibrational energy to the patient's skin.

Abstract: This invention relates to a medical skin treatment device, comprising a control unit for controlling the operation of the skin treatment device, a power supply unit for supplying power to the medical skin treatment device, and a main body including a drug storage unit for storing medication to be injected into the patient's skin, a transport unit for moving the main body, a handpiece that receives power from the power supply unit of the main body, is controlled by the control unit, and injects the drug into the patient's skin to improve the skin, and a drug supply unit coupled to the drug storage unit that supplies a predetermined amount of drug to the handpiece.

Abstract: Provided is a medical skin treatment device including a control unit for controlling the operation of the skin treatment device; a main body which includes a transfer unit and a power supply unit; and a handpiece which is supplied with power from the power supply unit and controlled by the control unit and one side of which is brought into contact with a patient's skin to irradiate same with laser beams. The handpiece includes at least four different laser diodes; the at least four laser diodes radiate laser beams of four different wavelengths and comprise first laser diodes, second laser diodes, third laser diodes, and fourth laser diodes; the number of the first laser diodes is 30 percentage or less of the total number of the laser diodes; and the number of the fourth laser diodes is 25 percentage or greater of the total number of the laser diodes.

Abstract: A pressure vessel for storing high-pressure gas has a structure including: a nozzle body which is coupled to a vessel body that defines an inner wall surface of the pressure vessel, and has an inner flow path through which gas flows inside and outside of the pressure vessel; and a locker which is fastened to a lower portion of the nozzle body, and the structure is configured to provide dual sealing including sealing at an inclined surface by fastening force of the locker generated by an inclined pressing end of the locker, and sealing in the locker by sealing members.
