Intracranial pressure, or the pressure exerted by the cranial cavity's contents on the cranial walls, normally remains relatively stable. However, when the brain is injured or pathologically damaged, intracranial pressure may fluctuate abnormally. The purpose of an intracranial pressure monitoring device is to promptly and accurately measure intracranial pressure, providing crucial information for doctors to diagnose conditions, formulate treatment plans, and evaluate treatment effectiveness.

[0003] The patent application with application number CN202110495269.1 discloses a new intracranial pressure monitoring device; the present invention includes a monitor and a horizontal component, a detection component and a balance component controlled by it. The horizontal component includes an electric telescopic rod, a support plate and an electronic gyroscope. Electric telescopic rods are provided at the top corners of the top surface of the monitor, and the top of the electric telescopic rod is provided with a hinge ball. The top corners of the bottom plate of the support plate are provided with a ball hinge seat matching the hinge ball. The detection component includes a U-shaped tube, a distance sensor and an air pressure sensor. The U-shaped tube is provided with a sealing plug at the tube mouth, and the bottom of the sealing plug is provided with a distance sensor and an air pressure sensor. The U-shaped tube is provided with a connecting tube on the tube body near its tube mouth, and the U-shaped tube is filled with detection liquid. The balance component includes a mounting seat, an air storage tank, an air supply pipe, a pressure relief pipe and an electromagnetic pressure relief valve; it can effectively solve the problems of poor safety and large measurement errors in the existing technology.

[0004] In existing equipment, a miniature pressure detection device is placed into the cranial cavity through surgery. However, after the existing surgery, the wound is wrapped with medical cotton or gauze, which may expose the wound to the air. Due to the complex composition of the air in the hospital, there is a possibility that the patient will become infected. Summary of the Invention
