Description

First aid cooling device

The invention relates to a treatment device, in particular to a first-aid cooling device.

When the heartbeat of the human body stops, the heart is unable to pump blood, causing blood flow to stagnate. Oxygen cannot be supplied to various organs of the body and cause hypoxia. Among them, hypoxia has the most influence on the cranial nerves. When hypoxia is 4 minutes to 6 minutes. Brain cell damage begins to occur, and even if the patient recovers the heartbeat after first aid, most of the patient's brain has caused permanent damage and even become a vegetative person.

The principle of therapeutic hypothermia (TH) is to reduce the oxygen metabolism rate of the brain by about 7% for every 1 °C decrease in body temperature. Low body temperature can also reduce brain electrical activity, reduce free radical production, and inhibit cell death. The path of death, lowering brain pressure and reducing systemic metabolic rate and oxygen consumption. In the past decade, many studies have confirmed that hypothermia can improve the survival rate and neurological prognosis of patients with coma after emergency arrest after cardiac arrest, and can improve the recovery possibility of unconscious patients after stroke, brain trauma or drowning. Protect the nerves of patients with spinal injuries.

The implementation of hypothermia treatment can be divided into three stages: rapid cooling period, low temperature maintenance period, and slow recovery period. According to the American Heart Association's 2010 guidelines for hypothermia, acute cardiac arrest patients recover their heartbeat and blood circulation after first aid. If you are still in a coma and can maintain ventilation and blood pressure, you should consider hypothermia, and quickly cool the patient's central body temperature to between 32 ° C and 34 ° C for at least 24 hours. The main purpose is to improve the patient. Survival rate and protection of the cranial nerves; after 24 hours of low temperature, it begins to slowly warm up by 0.25 °C per hour until it returns to normal body temperature; the temperature should be avoided too fast, otherwise it may cause electrolyte abnormalities in patients. , epilepsy, cerebral edema or hypotension.

Because hypothermia may affect human physiological changes and other complications, the patient's vital signs should be closely monitored during the implementation; however, because people are warm-blooded animals, if the body temperature is regulated by traditional ice packs and ice blankets, the cooling rate is too slow.
