Fever is one of the most common childhood diseases. Babies have fever from childhood to adulthood. Statistics show that ordinary preschool children under the age of 4 have an average of 6 to 9 fevers in a year. Has been a high fever, damage to the nervous system and gastrointestinal system. Therefore. After the baby has a fever, there will be depression, frequent distress, food aversion, nausea and vomiting and other symptoms. When a patient with a high fever goes to the hospital, the doctor will use physical cooling plus drug treatment. When a patient with a high fever is physically cooled, the doctor will put a bag of ice under the patient's head. The hypothalamus controls the changes in body temperature, and the location of the hypothalamus and the location of the large blood vessels in the head are close to the back of the brain, so ice is the most effective way to physically cool the head. The product is designed to support and fix the head. The product adopts a semiconductor refrigeration system, which actively cools down. It can be adjusted from zero to 30 degrees Celsius in the refrigeration mode, and music can be played while cooling down. One is to let the patient relax, calm and assist in cooling. The second is to neutralize the noise generated by the fan's heat dissipation. The music is small in decibels and can only be heard close to it, so it will not affect other people. The product consists of a base, a refrigeration system, a latex pillow, a thermal insulation gel, a sound module and a coat covered on the surface. The semiconductor refrigeration sheet is attached to the thermal insulation gel for continuous refrigeration. Because the liquid and latex are soft, the head can be prevented from directly contacting hard objects. In addition, the product also has functions such as temperature display, temperature adjustment, timing setting, etc., which is convenient for doctors to operate, observe and record. In addition to children's use, adults can also use it. Due to the characteristics of semiconductors, after being energized, one side is cold and the other is hot. By changing the direction of the current, two modes of cooling and heating can be set. The cooling mode can relieve dizziness and headache with ice compress. Heating mode, for cervical spine pain, shoulder blood circulation is not smooth, hot compress can relax muscles and promote blood circulation.
