Description

technical field

[0001] The invention belongs to the technical field of biomedical medical devices, and in particular relates to an inspection device for cerebral edema in neurology and surgery. Background technique

[0002] Intracerebral surgical diseases such as various craniocerebral trauma, brain tumor resection, cerebral ischemia, brain tumor, encephalitis, and high altitude cerebral edema have entered the top three common fatal lesions in terms of morbidity and mortality. These intracerebral surgical diseases are accompanied by symptoms of cerebral edema. According to the different pathogenesis and pathological changes of cerebral edema, it can be divided into two categories: extracellular edema mainly caused by blood vessels and intracellular edema mainly caused by cytotoxicity. Correctly distinguishing the types of cerebral edema is an important basis for doctors to grasp the patient's condition, determine the treatment plan, and use the correct medication and treatm...
