Problems solved by technology

However, through a large number of clinical observations, it was found that the main reason for the blockage of the shunt tube is not that the tip of the shunt tube is closed by the brain tissue, but that the cerebrospinal fluid in the ventricle hardly flows spontaneously, resulting in the formed components in the cerebrospinal fluid, such as proteins and carbohydrates. , and even free cells deposit and attach at the outlet hole of the shunt pipe, which eventually leads to blockage of the outlet hole of the shunt pipe

Abstract

A device capable of automatically adjusting shunt volume of cerebrospinal fluid and preventing a shunt tube from being blocked comprises a pressure sensor, the Y-shaped shunt tube, a transfer pump, a first programmed switch, a second programmed switch, a loading plate, a first electronic control system, a first power source, a second electronic control system and a second power source. The first programmed switch is used for communicating or cutting off a passage for cerebrospinal fluid to flow between two upper arm catheters of the Y-shaped shunt tube. The second programmed switch is used for communicating or cutting off a passage for cerebrospinal fluid to pass through a lower arm catheter of the Y-shaped shunt tube and enter the abdominal cavity. The transfer pump is used for driving cerebrospinal fluid in the Y-shaped shunt tube to flow. The pressure sensor is used for collecting pressure in the cranium. The first electronic control system is used for controlling the state of the transfer pump, the first programmed switch and the second programmed switch according to situations of the pressure in the cranium, and transmitting relative information to the second electronic control system. The second electronic control system is used for receiving and displaying the information of the first electronic control system, and sending an instruction to the first electronic control system.

Description

technical field [0001] The invention belongs to medical equipment, and particularly relates to a device for regulating the shunt flow of cerebrospinal fluid according to the intracranial pressure and preventing the blockage of the shunt tube after neurosurgical ventricle-peritoneal shunt. Background technique [0002] Ventriculoperitoneal shunt surgery is a common operation in neurosurgical treatment of hydrocephalus. After ventriculoperitoneal shunt surgery, by placing a shunt between the ventricles and the abdominal cavity, the excess cerebrospinal fluid in the ventricles is shunted into the abdominal cavity, which can relieve the symptoms of intracranial hypertension in patients, but the intracranial hypotension caused by excessive shunting may also affect the Patient poses a fatal threat. During the shunt process, the blockage of the shunt tube is one of the most common and troublesome complications after ventriculo-peritoneal shunt surgery. According to reports, the ra...
