Description

Cryogenic treatment system Technical Field The embodiment of the application relates to the technical field of medical instruments, in particular to a low-temperature treatment system. Background Cryotherapy has made significant progress in lowering intracranial pressure and neuroprotection as an important clinical tool. Studies have shown that by controlling the core temperature of the patient to the sub-low temperature range (32-36 ℃) secondary damage following brain injury can be effectively reduced. The ice cap is mainly used for cooling the head, can effectively reduce the temperature of the cranium, reduce the metabolism and oxygen demand of brain cells, improve the tolerance of the brain cells to hypoxia, and prevent cerebral edema.

The duration of the cryogenic treatment and the rate of rewarming may vary widely from patient to patient, and improper cryogenic treatment or rewarming may result in secondary injury to the patient.
