In Article 1, A patient cooling device utilizing an alcohol spray, characterized in that the above-mentioned fever-reducing cover is either a blanket-type cover in which a portion of the fever-reducing cover is placed on a bed and the patient is placed on it, and the remaining portion of the fever-reducing cover is used to cover and secure the patient, or a garment-type cover worn on the patient's body.
3. In Article 1, A patient cooling device utilizing an alcohol spray, characterized in that the sealing means of the above-mentioned heat-reducing cover is either a zipper or Velcro tape.
4. In Article 1, The above-mentioned heat-reducing cover is a patient cooling device utilizing an alcohol spray, characterized by having an alcohol outlet installed at the bottom centering the patient's body to discharge used alcohol to the outside.
5. delete
6. delete
7. In Article 1, A patient cooling device utilizing an alcohol spray, further comprising a control unit that controls a device connected to the alcohol spray unit and the air injection unit to spray alcohol or inject air into the heat-reducing cover.
8. In Article 1, A patient cooling device utilizing an alcohol spray, comprising a blower connected to the alcohol supply pipe and lowering the patient's temperature by spraying air through the spray nozzle.
9. In Article 7, A patient cooling device utilizing an alcohol spray, comprising an alcohol control unit that controls the amount of alcohol injected by controlling the spray speed and spray time of the alcohol sprayed onto the heat-reducing cover.
10. In Article 7, The above control unit is a patient cooling device utilizing an alcohol spray, comprising a temperature control unit that controls the temperature of the air supplied to the interior of the heat-reducing cover.

Description

Alcohol Spray Utilized Patient Cooling Device The present invention relates to a patient cooling device utilizing an alcohol spray. Fever refers to an increase in core body temperature due to an elevation of the thermoregulatory center's fever point, and typically means that the rectal temperature rises above 38 degrees. It is known that when body temperature rises by 1 degree, the basal metabolic rate increases by 10-12%, the oxygen consumption rate by 13%, the heart rate by 15 beats per minute, and the insensible water loss per body surface area by 300-500 ml per day. The causes of fever can be broadly classified into infectious and non-infectious causes. Infectious causes are diverse and include pneumonia, enteritis, wound infections, nervous system infections, and urinary tract infections. If left untreated, all types of infections can progress to sepsis and septic shock, and in many cases where patients are admitted to the intensive care unit, sepsis or shock has already developed. When a fever occurs, antipyretics are administered to alleviate worsening physical symptoms, along with treating the underlying disease causing the fever. The antipyretics used are mainly acetaminophen or non-steroidal anti-inflammatory drugs. However, in the case of elderly patients or those whose disease has worsened and who have fallen into multiple organ failure, the function of organs such as the liver or kidneys is often impaired. In these patients, long-term use of acetaminophen-based antipyretics can lead to renal dysfunction, and high-dose administration can lead to liver dysfunction. In the case of non-steroidal anti-inflammatory drugs, they can cause indigestion, gastrointestinal bleeding, and reduced renal blood flow, and in severe cases, permanent organ damage may occur, making it difficult to regulate the body temperature of patients with fever. Alcohol is used to lower a patient's temperature when such a fever occurs; similar to the principle of vaporization, as alcohol evaporates from a liquid state into a gas, it absorbs surrounding thermal energy and can lower the patient's body temperature. However, the aforementioned alcohol is inconvenient to use because it must be applied to gauze in solution form and used by medical staff to wipe the patient.

FIG. 2 is a drawing illustrating the state in which a patient cooling device according to one embodiment of the present invention is applied to a patient. FIG. 3 is an enlarged view of the internal structure of a patient cooling device according to one embodiment of the present invention. FIG. 4 is a diagram illustrating a control system of a patient cooling device according to one embodiment of the present invention. FIG. 5 is a diagram illustrating the state in which alcohol is sprayed or air is injected into the interior of a patient cooling device according to one embodiment of the present invention. Hereinafter, an embodiment of a patient cooling device utilizing an alcohol spray according to the present invention will be described with reference to the attached drawings. At this time, the present invention is not limited or restricted by the embodiments. Furthermore, in describing the present invention, specific descriptions of known functions or configurations may be omitted to clarify the gist of the present invention. FIG. 1 is a drawing illustrating a patient cooling device utilizing an alcohol spray according to an embodiment of the present invention. FIG. 2 is a drawing illustrating the state in which the patient cooling device according to an embodiment of the present invention is applied to a patient. FIG. 3 is an enlarged drawing illustrating the internal structure of the patient cooling device according to an embodiment of the present invention. Referring to FIGS. 1 to 3, a patient cooling device (1) utilizing an alcohol spray according to the present invention includes a heat-reducing cover (10), an alcohol spraying unit (20), and an air injection unit (30), and can maintain the patient's body temperature by automatically spraying alcohol onto the patient while the patient is wrapped in the heat-reducing cover (10) to lower the patient's temperature. In this embodiment, the heat-reducing cover (10) of the patient cooling device (1) is configured to have an internal space to accommodate a patient and to be openable and closable through an outer sealing means (11), and the alcohol spraying unit (20) sprays alcohol onto the patient's body through a plurality of spray nozzles (21) arranged along the outer edge of the heat-reducing cover (10). In addition, the air injection part (30) of the patient cooling device (1) injects external air into the space between the heat-reducing cover (10) and the alcohol injection part (20) to form a certain space, thereby expanding the internal space of the heat-reducing cover (10)
