Abstract
Proposed is a laser treatment device having a cooling system, the device including a laser module which irradiates a patient's skin with a laser, a sensing unit which detects a temperature of a surface of the patient's skin before, during, or after the skin is heated by the laser, a cooling module which includes an inlet which receives a refrigerant from a refrigerant storage unit, a nozzle which sprays the refrigerant on the skin, a conduit which connects the inlet with the nozzle, an flow rate control unit which controls a spray amount of the refrigerant by using a valve which is positioned on the conduit and connects or disconnects the inlet with or from the nozzle, and a refrigerant condition control unit which applies a thermal energy to the refrigerant by using a thermoelectric element located between the flow rate control unit and the nozzle.
