Ventricular drainage tube and use method thereof

Abstract

The ventricular drainage tube comprises a drainage tube body and a guide wire, the drainage tube body comprises a drainage cavity at the front end and a flow guide cavity at the rear end, the drainage cavity is made of elastic materials, and the guide wire penetrates through the flow guide cavity to move relatively in the drainage cavity and moves out of the drainage cavity. The drainage cavity is self-recovered to be of an arc-shaped bent structure under the action of elastic force. The invention further provides a using method of the ventricular drainage tube. According to the ventricular drainage tube, the drainage cavity with the elastic memory function is adopted, the drainage cavity is in an arc-shaped bent state during drainage so that the contact area of the drainage cavity in an intracranial drainage area can be increased, sufficient drainage can be achieved, and craniocerebral injury caused by the fact that the drainage cavity is inserted too long can be avoided; when the drainage cavity is removed, the drainage cavity is in a linear state under the action of the guide wire so that the drainage cavity can be smoothly detached, and the drainage tube is simple in design structure, convenient to operate, not prone to blockage and sufficient in drainage.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a cerebral ventricle drainage tube and a method for using the cerebral ventricular drainage tube. Background technique [0002] The purpose of extraventricular drainage is, usually, to treat hydrocephalus. Intraventricular hemorrhage can be caused by high blood pressure, hemorrhagic stroke, bleeding from a ruptured aneurysm, bleeding from an arteriovenous malformation, or head trauma. When blood enters the ventricular system, the circulation of cerebrospinal fluid is blocked due to blood coagulation, resulting in obstructive hydrocephalus. Furthermore, in addition to the toxic effects on the ependyma and adjacent brain parenchyma, blood clots can also cause significant mass effects on adjacent brain structures. [0003] In order to control the increase of acute intracranial pressure caused by hydrocephalus, the drainage tube is usually inserted into the ventricle to d...
