An intensive care device using anions comprising: a body part in which a main board is mounted in the interior thereof, in which a touchscreen is provided on a front surface thereof, and in which moving wheels are installed on the lower side thereof; a head part connected to one side of the body part by an arm hinge to be movable, and in which an anion generating unit electrically connected to the main board is operatively installed; and an anion irradiating part connected to one side of the head part such that the angle thereof is adjusted and electrically connected to the anion generating unit such that anions generated from the anion generating unit are irradiated to an outside through an end thereof, wherein the anion irradiating part includes: a pair of connecting members connected to the head part in a bellows tube manner such that the angles thereof is adjusted; and irradiation members installed at ends of the pair of connecting members, respectively, and configured to irradiate anions, characterized by a human body grounding device electrically connected to the anion generating unit, and electrically grounded to a portion of the human body of a patient, wherein the irradiation members include: anion irradiating needles protruding from a lower surface of the corresponding one of the pair of irradiation members, the number of which corresponds to the number of the anion generating units, electrically connected to the anion generating unit, and a tip end of which is manufactured in a sharp needle shape such that anions are irradiated through the end thereof; a low-output light irradiation lens provided on a lower surface of the corresponding one of the pair of irradiation members to be turned on and off and from which light of a blue wavelength is irradiated; and a sensor protruding from a lower surface of the corresponding one of the pair of irradiation members, and extending further than the anion irradiating needle such that an operation of the intensive care device using anions is interrupted when an end of the sensor connected to a portion of the human body. a body part in which a main board is mounted in the interior thereof, in which a touchscreen is provided on a front surface thereof, and in which moving wheels are installed on the lower side thereof;
