Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for cooling treatment of patients after cardiopulmonary resuscitation recovery. Background Art

[0002] Cardiac arrest (CA) is one of the main causes of adult death worldwide, with millions of cases occurring each year. According to relevant information, currently, timely and effective cardiopulmonary resuscitation (CRP) is the only treatment measure for patients with cardiac arrest, but the survival rate of patients who are successfully treated and discharged is <7%, and neurological injury is the main cause of death and disability in patients. Targeted

[0003] temperature management (TTM) is an induced targeted temperature management (32 - 36°C) for reducing neurological injury in patients, which is an important part of brain protection treatment for patients with cardiac arrest after CRP restores spontaneous circulation, and is also an important method that has been clinically proven to improve the prognosis of patients and the recovery of neurological function. Specifically, TTM after cardiac arrest refers to the process of rapidly reducing body temperature to the target temperature using physical methods, maintaining it at a constant temperature for a period of time, and then slowly rewarming to the basal body temperature, while avoiding body temperature rebound. TTM has become a routine treatment method for patients with cardiac arrest.

[0004] The neuroprotective mechanisms during TTM mainly include the following aspects: 1) Reducing cerebral metabolism. When the body temperature decreases by 1°C during TTM treatment, cerebral metabolism decreases by 5% - 10%. 2) Alleviating oxygen metabolism disorders in brain tissue. After cardiopulmonary resuscitation, the intracranial temperature can exceed the core body temperature by 2 - 4°C. Hypothermia treatment can reduce the intracranial temperature and improve the hypoxia tolerance of brain tissue. 3) Protecting the blood-brain barrier and alleviating brain edema. Hypothermia treatment can reduce or reverse the damage of cell membrane integrity and hypoxia-induced vascular leakage by regulating the expression of matrix metalloproteinases, thereby treating brain edema and reducing intracranial pressure. In addition, hypothermia treatment can also inhibit apoptosis, reduce oxidative stress, inhibit immune responses and inflammation, and inhibit the production of excitatory neurotoxic substances. Currently, the conclusion about the starting time of TTM is consistent. The earlier TTM starts, the better the effect. It is recommended to start TTM within 8 hours after spontaneous circulation recovery. Although it is also beneficial beyond 8 hours, the longer the delay, the less the benefit. Therefore, rapid and safe cooling may improve the neurological prognosis of patients. Currently, the treatment of early pre-hospital brain protection is relatively lacking in China. Therefore, it is very necessary to develop a device that can help patients after cardiopulmonary resuscitation quickly control their body temperature. Summary of the Invention

[0022] As Figures 1 to 2 shown, the present invention provides a device for cooling treatment of patients after cardiopulmonary resuscitation. The metal ventilation pipe 13 therein is made of a thin-walled copper pipe with significant conduction effect. The usage method is as follows: First, seal and connect each component with the circulation fan 15, place the box body 12 under the air outlet 11 of the air conditioner indoor unit 10, set the air outlet temperature of the air conditioner indoor unit 10 at 32 °C, and turn on the circulation fan 15. If the thermometer 9 shows that the temperature of the metal ventilation pipe 13 is 32 °C, the temperature in the plastic ventilation hose 7 is also 32 °C at this time. Second, the circulation fan 15 inputs uniformly cooled air into the head sandwich cloth cap 6, middle connecting sandwich cloth bag 5, neck sandwich cloth bag 4, back sandwich cloth bag 3, abdominal sandwich cloth bag 2 and femoral groin sandwich cloth bag 1. Third, lay the back sandwich cloth bag 3 and the head sandwich cloth cap 6 flat on the cooling treatment bed. Immediately after the patient's cardiopulmonary resuscitation, lift the patient onto the cooling treatment bed and lie flat on the back sandwich cloth bag 3, put the head sandwich cloth cap 6 on the patient's head, and place the remaining cloth bags at the corresponding positions on the patient's body for rapid cooling. Fourth, due to different seasons and different temperatures and environmental temperatures in ambulances or ICU rescue rooms, to make the air outlet temperature of the air conditioner indoor unit 10 the same as the temperature of the metal ventilation pipe 13, it must be pre-operated. When the thermometer 9 shows that the temperature of the metal ventilation pipe 13 is in the range of 32 - 36 °C, the cooling treatment of the patient's body can be started. To ensure the cooling effect, a layer of cloth can be added to the outer surfaces of the femoral groin sandwich cloth bag 1 and the abdominal sandwich cloth bag 2.
