Oral cooling device utilizing cooling balloon

An oral cooling device using a cooling balloon, the oral cooling device comprising:

• a cooling water supply portion having therein a cooler that is configured to cool cooling water and a pump that is configured to supply and recover the cooling water;
• a cooling water hose portion connected to the cooling water supply portion at one end portion of the cooling water hose portion to transfer the cooling water and recover the cooling water to the cooling water supply portion;
• a cooling balloon portion configured to expand by the cooling water to cool an inside of an oral cavity of a patient after being inserted into a mouth of the patient, the cooling balloon portion being configured to contract when the cooling water is recovered to the cooling water supply portion, the cooling balloon portion branching into a plurality of branches, a distal end of each of the plurality of branches having a balloon attached thereto to separately cool a plurality of mucosal areas inside the oral cavity;
• and
• a connection pipe portion,
• wherein the connection pipe portion includes:
• a fixed pipe having one end detachably connected to the cooling water hose portion;
• a cooling balloon portion connection pipe having one end detachably and rotatably connected to another end of the fixed pipe, another end of the cooling balloon portion connection pipe being detachably connected to the cooling balloon portion, the cooling balloon portion connection pipe having a cooling balloon portion gear on an outer surface thereof;
• a mouthpiece disposed on an outer surface of the fixed pipe and configured to enable the patient to bite and fix the fixed pipe;
• and
• a rotational driving portion disposed on the outer surface of the cooling balloon portion connection pipe, the rotational driving portion having a motor gear axially engaged with the cooling balloon portion gear,
• wherein the rotational driving portion is configured to rotate the cooling balloon portion connection pipe relative to the fixed pipe while the fixed pipe remains stationary when the patient bites the mouthpiece, such that the cooling balloon portion connected to the cooling balloon portion connection pipe rotates about an axial direction of the fixed pipe by a predetermined angle within the mouth of the patient.
