A ventriculo-peritoneal cerebrospinal fluid shunt device

Abstract

Provided is a ventricle-abdominal cavity cerebrospinal fluid diversion device. The diversion device comprises an outer water bag used for being imbedded into the subcutaneous part of the abdominal cavity of a patient, and a catheter used for draining cerebrospinal fluid in the ventricle to the abdominal cavity, an inner water bag used for squeezing the catheter is arranged on the outer wall of the catheter in a sleeved mode and communicated with the outer water bag through a water injecting tube, a check valve used for guiding fluid in the outer water bag into the inner water bag is arranged on the water injecting tube, a fluid pumping opening for releasing the fluid in the inner cavity of the inner water bag is formed in the inner water bag, and the fluid pumping opening is sealed through a silica gel sealing gasket in which a fluid pumping needle pierces. When the diversion device is used, a medical worker squeezes the outer water bag outside the body of the patient, the fluid in the outer water bag can be squeezed into the inner water bag through the water injecting tube, the inner water bag expands to make the inner diameter of the catheter clamped in the inner water bag reduce, and therefore the drainage amount of cerebrospinal fluid in the catheter can be adjusted, the ventricle-abdominal cavity cerebrospinal fluid diversion device is very good in clinical safety, and the requirement of cerebrospinal fluid for circulation pressure is met.

Description

technical field [0001] The invention relates to the technical field of hydrocephalus lateral ventriculoperitoneal shunt, in particular to a ventricle-peritoneal cerebrospinal fluid shunt device. Background technique [0002] For patients with intracranial infection who need to be complicated with hydrocephalus, external drainage through the lateral ventricle or lumbar drainage is generally used clinically. Lateral ventricular drainage is to absorb the cerebrospinal fluid accumulated in the ventricle through the abdominal cavity, so that the absorption and secretion of cerebrospinal fluid are completely balanced. The optimal shunt flow and the corresponding intracranial pressure vary from person to person. Most of the pressure regulators used in the current shunt devices are pressure pumps, which basically only have three gears: high pressure, medium pressure and low pressure. In the actual clinical application, it is difficult to choose the optimal pressure for the patient,...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the pressure selection of the shunt device is limited, and it is difficult to adjust the continuous pressure and drainage volume according to the change of the patient's condition, and provide a ventricle-peritoneal cerebrospinal fluid shunt device
