Description

DESCRIPTION WEARABLE HUMAN BODY COOLING DEVICE TECHNICAL FIELD

[01] The present disclosure relates to the technical field of medical auxiliary equipment, particularly to a wearable human body cooling device.

BACKGROUND

[02] With the increasing development of traffic and the rapid increase in the number of family cars per capita, the occurrence rate of traffic accident injuries has increased sharply. Brain injury occurs in most cases. The aging process is accelerated, and there are more and more cerebrovascular accidents (strokes). There are clinical requirements for cerebral resuscitation after a critical patient suffers from sudden cardiac arrest and requires cardiopulmonary resuscitation. Under the above circumstances, the brain tissue has become the focus of current research. In clinical cases of cerebral resuscitation for stroke and after craniocerebral surgery and cardiopulmonary resuscitation, the temperature of the brain tissue needs to be lowered to greatly reduce brain cell metabolism, reduce the production of acidic metabolites and oxygen free radicals, reduce brain tissue edema, and protect the function of the brain cells. In addition, a low temperature can also contract intracranial blood vessels and reduce intracranial hemorrhage.

[03] Due to the late stage of a serious illness or coma after a severe brain trauma, it is necessary to protect the brain tissue cells from irreversible injury, and it is necessary to quickly cool part of the brain and maintain cooling for a long time. At present, ice caps, neck ice bags, 4°C liquid infusion, or other methods are commonly used to reduce the temperature of the brain tissue to achieve the purpose of brain protection, but an actual effect and a rapid response effect are not satisfactory. Especially in the case of central high fever, the effect will be worse when the whole body temperature rises. During use, ice cubes (or ice water) must be constantly prepared, and ice water in the ice caps and the ice bag must be replaced frequently, which brings cumbersome work to nursing staff. However, an existing scarf-like cooling device 1s limited to the cooling of great vessels in the neck, and the cooling effect is poor.
