The invention relates to the technical field of medical monitoring and early warning, and discloses a postoperative care risk early warning system for neurosurgical patients. According to the system, real-time monitoring flows of electroencephalogram, intracranial pressure and body surface myoelectricity of a patient are continuously received, and a dynamic interaction network of neuroelectrophysiology and intracranial mechanical states is constructed so as to represent the coupling relation among electroencephalogram rhythm, pressure conduction and postoperative skull windowing area tissue compliance. The system analyzes three types of core parameters of cerebral cortex excitability, cerebrospinal fluid circulation load and cranial cavity compensation space from the network, further calculates a brain tissue perfusion risk and a neural structure compression risk, and generates a corresponding nursing early warning signal and a physiological regulation path. According to the scheme, deep coupling and mechanism risk early warning of multiple physiological signals are achieved, and the postoperative complication risk can be recognized earlier and more accurately.

A system and method for high-resolution, non-invasive characterization of a cranial cavity and its contents through an intact skull.

The present application relates to the technical field of intracranial blood vessel ultrasound training model, specifically to an intracranial blood vessel TCD simulation training model, comprising a peristaltic pump, the input end and the output end of the peristaltic pump are connected with conveying pipelines, the peristaltic pump is provided with a head model on one side, the head model comprises a head model body, the head model body has a simulated cranial cavity, the top of the simulated cranial cavity has a placing opening, the upper part of the placing opening has an openable cover; the outer side of the head model body has a temporal window, an occipital window and an eye window; the inside of the simulated cranial cavity is filled with a plurality of brain tissue simulation gels, the brain tissue simulation gels are embedded with adjustable simulation blood vessel network structures arranged according to the structure of Willis ring, the input end and the output end of the adjustable simulation blood vessel network structures are respectively connected with the output end and the input end of the peristaltic pump. The present application solves the problems that the existing clinical TCD doctor training relies on direct operation on patients, has many defects, lacks special simulation training model, cannot evaluate the accuracy of doctor operation and limits the application of TCD technology.

The application discloses an intracranial hematoma ultrasonic crushing device and relates to the field of medical equipment, which comprises an ultrasonic vibration rod, an adhesion device and a reflux pipe, the reflux pipe is arranged at the end of the adhesion device far from the ultrasonic vibration rod, and a reflux pipe inner cavity is arranged in the reflux pipe; a drainage pipe and a suction pipe are arranged on the rod end cover. The application can realize ultrasonic crushing and discharge of intracranial hematoma, is clean and complete, avoids residue, enables blood clots to be fully adsorbed and discharged, and enables the cerebrospinal fluid pressure in the cranial cavity to be normal and not to be blocked. The trace suction and supply type purifies the cerebrospinal fluid, does not affect the intracranial pressure, and avoids the phenomenon of unstable intracranial pressure.

A device that can be placed within or near the cranial vault that fluctuates in size in response to changes in CSF pressure is disclosed. The device diminishes in size when CSF pressures rise and increases in size as CSF pressures diminish. The device has the effect of reducing the flow of CSF occurring in the foramen magnum and provides an alternative to craniovertebral decompression in Chiari I patients. The device may have applications in other neurologic illnesses associated with abnormal CSF flow, such as Idiopathic Syringomyelia, Normal Pressure Hydrocephalus, and CSF dural leaks.

The application relates to the field of interventional medical technology, in particular to a percutaneous interventional venous sinus puncture access device. The access device is formed by the mutual cooperation of a balloon catheter, a deflecting catheter and a puncture guide wire, can puncture into the subarachnoid cavity in the cranial cavity on the venous sinus without damaging the brain, break the dura mater and arachnoid, construct a stoma between the pontocerebellar angle pool and the inferior petrosal sinus, and make the cerebrospinal fluid flow from the subarachnoid cavity to the venous sinus, to the jugular vein and to the heart, and participate in blood circulation. The access device can also be used for delivering a shunt, so that the hydrocephalus which can only be effectively treated by operation in the past can be treated by a minimally invasive interventional method, the access device is not used for surgical open operation, the intraoperative trauma is reduced, the operation time is saved, and the possibility of postoperative infection is greatly reduced.

The invention belongs to the technical field of medical apparatus and instruments, and provides a brain tumor interstitial cavity fluid circulation intervention device which comprises a brain intervention device, the brain intervention device is of a spherical net structure, and a collecting hole and a discharging hole are formed in the surface of the brain intervention device; the external circulator is used for being arranged under the scalp outside the craniocerebral cavity to provide power for circulation of interstitial cavity fluid and serving as an intervention portal; the auxiliary circulation assembly comprises an auxiliary circulator and an auxiliary intervention device, and the auxiliary intervention device is of a balloon structure with holes. The brain tumor interstitial cavity fluid circulation intervention device has the functions of accurately monitoring brain tumor evolution in real time, accurately diagnosing tumor recurrence in an early stage and directly and locally treating recurrent tumors, and is used for solving the technical problems of whole-course sampling monitoring and accurate diagnosis and treatment after brain malignant tumor operation; particularly, an interventional tool is provided for solving the technical problems of sampling monitoring, early precise diagnosis and direct local treatment in the recurrence and progression stage after brain malignant tumor treatment.
