The present invention relates to an intensive care device using anions which: makes a body of a patient be in a static induction state by a grounding while radiating anions directly to the affected part so as to enable the affected part to be healed quickly, and induces anions to the body direction of the patient with anionic charge having straightness when radiating anions to the affected part in the static induction state, thereby having excellent effects of minimizing anion loss by cations in air and maximizing irradiation facing an affected part exerts beneficial effects on a human body such as sterilization of skin by including a low power light irradiation lens radiating light of a blue wavelength which is a low output beam and is convenient in use thereof and procedure compared to skin transplantation and other skin regenerative medicines. According to an embodiment of the present invention, the intensive care device using anions includes: a main body unit which has a main board installed inside, has a touch screen in the front side, and has a movable wheel installed in the lower side a head unit which is connected with one side of the main body to be able to move by an arm hinge, and has an anion generation unit connected electrically with the main board to be embedded to be able to operate an anion irradiation unit which is connected to one side of the head unit to be able to control an angle, and radiates ions generated from the anion generation unit to be radiated to the outside through an end part by being electrically in contact with the anion generation unit and a grounding unit which is electrically connected with the anion generation unit, is electrically grounded on a body part of a patient, and minimizes the loss amount of anions, radiated from the anion irradiation unit, in the air, and maximizes an irradiation amount of anions to the body part of the patient by an electrostatic induction phenomenon due to a body grounding.본 발명은 환부에 음이온이 집중 조사되게 하
