Skull defects are common disease states in modern neurosurgery, and a part of skull is removed after craniocerebral operation due to craniocerebral trauma, bleeding, tumor and the like so as to save lives. The lacking area of the skull is lack of hard material protection, and the brain tissue is very easy to be collided or extruded to be hurt. Most patents or articles currently focus only on preventing the brain from being damaged by impact or compression at the site of the skull defect.

However, after the craniocerebral operation, the skull is removed, the solid closed environment of the cranial cavity is damaged, the atmospheric pressure directly passes through the scalp and is conducted to the brain, so that cerebral microcirculation and metabolic disturbance are caused, the brain function is affected, and complications such as epilepsy, limb dysfunction, paraesthesia, epilepsy, hydrocephalus and the like occur. Severe collapse of scalp and brain tissue can lead to a severe disease state known as "flap collapse syndrome" in medicine, which is life threatening. Flap collapse syndrome is more likely to occur in a sitting or upright position and can lead to death of the patient in a short period of time. Therefore, a simple and portable brain protection device is very necessary for the patient with the skull defect.
