The present invention relates to an intensive care device using anions, the device: intensively irradiating the affected area with anions such that the affected area is quickly healed, and allowing a patient's body to be in an electrostatically induced condition through grounding, and, in this condition, irradiating the affected area with anions such that an anionic charge is induced in the patient's body direction with linearity, thereby having excellent effects by minimizing anionic loss caused by cations in the air and maximizing the amount of irradiation directed toward the affected area； having a low-output light irradiation lens irradiated with blue wavelength light, which is a low-output ray, so as to exhibit a physically beneficial effect such as skin sterilization； and having a simple use and procedure compared with skin grafting or other medicines and medical supplies for skin regeneration.
