Device for adjusting drainage volume of ventricular cerebrospinal fluid based on intracranial pressure feedback

Abstract

The invention discloses a device for adjusting the drainage volume of ventricular cerebrospinal fluid based on intracranial pressure feedback. The device comprises a pressure sensor, a drainage tube, a programmed switch, a loading plate, a first electronic control system, a first power supply, a second electronic control system and a second power supply, wherein the drainage tube consists of a ventricle segment, a controlled segment and an abdominal cavity segment in sequence; the programmed switch is arranged in a groove on the loading plate at the controlled segment of the drainage tube, and is used for switching on / off a path on which the cerebrospinal fluid enters the abdominal cavity through the drainage tube; the pressure sensor is used for collecting the intracranial pressure; the first electronic control system is used for controlling the state of the programmed switch according to the state of intracranial pressure and transmitting relevant information to the second electronic control system; the second electronic control system is used for receiving and displaying information of the first electronic control system and sending instructions to the first electronic control system.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a device for automatically regulating the drainage volume of cerebrospinal fluid according to the intracranial pressure after neurosurgical ventricle-peritoneal shunt operation. Background technique [0002] Ventriculoperitoneal shunt surgery is a common surgical method for neurosurgery in the treatment of hydrocephalus. After ventriculo-peritoneal shunt surgery, by placing a drainage tube between the ventricles and the abdominal cavity, shunting the excess cerebrospinal fluid in the ventricles into the abdominal cavity can relieve the symptoms of intracranial hypertension in patients, but excessive drainage can lead to intracranial low pressure, causing cerebral palsy Neurological complications such as internal bleeding. Therefore, how to accurately adjust the cerebrospinal fluid shunt flow according to the real-time monitoring results of intracranial pressure is the key issue to ensure the...

AI Technical Summary

Problems solved by technology

However, for patients with ventriculo-peritoneal drainage who cannot monitor intracranial pressure in real time through an external pressure sensor, due to the shortcomings of poor measurement accuracy and cumbersome methods in the existing non-invasive indirect intracranial pressure measurement instruments, most patients Can only be detected on imaging studies after severe intracranial hypotension due to overdrainage of cerebrospinal fluid and clinically apparent symptoms

Although, for such patients, some patents propose a solution to control the drainage of cerebrospinal fluid by manually adjusting the mechanical switch placed under the skin, none of them can really solve the problem of accurately adjusting the drainage of intracranial cerebrospinal fluid according to the intracranial pressure monitored in real time. It will inevitably affect the recovery of the patient, and even endanger the life of the patient.
