Retroinfection-prevention enteric cavity shunting device for treating hydrocephalus

Abstract

The invention provides a retroinfection-prevention enteric cavity shunting device for treating hydrocephalus, and belongs to a medical appliance clinically used in neurosurgery departments. The shunting device comprises a shunting pipe, wherein the shunting pipe is divided into an abdominal cavity outer section, an inside-abdominal-cavity outside-intestine section and an intestine cavity inner section, a double-layer filtering cavity is arranged at the tail end of the intestine cavity inner section shunting pipe, an inner cavity is a micro-filtration membrane, the outer cavity is a hard filtering net, the shunting device is also provided with a flushing device consisting of a liquid storage bag and a flushing pipe, and one end of the flushing pipe is connected with the other end of the liquid storage bag and is arranged between the inner cavity and the outer cavity of the double-layer filtering cavity. The retroinfection-prevention enteric cavity shunting device has the advantages that the covering and blockage problems caused by the greater omentum on a shunting pipe outlet can be avoided, the cerebrospinal fluid can also be smoothly shunted, the micro-filtration membrane can also be utilized for preventing the intestine cavity germs from entering the shunting pipe, and the abdominal cavity infection caused by intracranial infection is also avoided. Meanwhile, the two-layer filtering device can be conveniently and repeatedly flushed by the incidental flushing device, the blockage is avoided, and the long-time efficient work of the device is ensured.

Description

technical field [0001] The invention belongs to a medical instrument for clinical use in neurosurgery, in particular to an anti-retrograde infection intestinal cavity shunt device for treating hydrocephalus. The device can avoid retrograde infection and can adapt to the environment with bacteria in the intestinal cavity. Background technique [0002] At present, the treatment of hydrocephalus is an international problem, which has puzzled clinicians for a long time. Although there have been many shunt devices for the treatment of hydrocephalus at home and abroad, the current shunt devices have many shortcomings: first, the omentum of many patients surrounds and blocks the end of the shunt tube, which makes the shunt fail; secondly, the ventriculoperitoneal shunt tube connects the ventricle With the abdominal cavity, cross-infection can occur between the ventricle and the abdominal cavity after the shunt. Once the retrograde infection causes intracranial infection, it can lea...

Problems solved by technology

Although there have been many shunt devices for the treatment of hydrocephalus at home and abroad, the current shunt devices have many shortcomings: first, the omentum of many patients surrounds and blocks the end of the shunt tube, which makes the shunt fail; secondly, the ventriculoperitoneal shunt tube connects the ventricle With the abdominal cavity, cross-infection can occur between the ventricle and the abdominal cavity after the shunt. Once the retrograde infection causes intracranial infection, it can lead to neurological dysfunction or even death. It is necessary to remove the shunt tube, anti-infection treatment, and then place a new shunt tube. caused great pain and financial burden

However, common peritoneal shunts are still used for enteroluminal shunts, and the risk of retrograde infection is higher during long-term use
