Bullet-shaped cerebral porous drainage tube and cerebral drainage device adopting same

Abstract

The invention discloses a bullet-shaped cerebral porous drainage tube and a cerebral drainage device adopting same, which comprises a bullet-shaped cerebral porous drainage tube, an input catheter, a metering reservoir, an output catheter, a liquid storage drainage bag and the like. The bullet-shaped cerebral porous drainage tube comprises a a tube body, the front end of the tube body is a dead end and the rear end thereof is a tube joint which is opened, the front end of the tube body is opened with at least two side holes, and the dead end is a bullet-shaped dead end. The invention has reasonable structure, the bullet-shaped dead end design of the drainage tube can reduce the damage to the brain tissue during the puncturing process, and has slippage effect, can slip to pass during the puncturing process if touching the blood vessel or nerves, thereby, the damage to the blood vessel and the nerves are prevented and avoided during the puncturing process, and intracranial hemorrhage, hematoma, aphasia, paralysis, neural paralysis and various complications can be reduced during the puncturing process.

Description

【Technical field】 [0001] The invention relates to a medical brain drainage device, in particular to the improvement of the drainage tube in the brain drainage device. 【Background technique】 [0002] Brain drainage device is used for the treatment of neurological and surgical hemorrhagic diseases (such as: intraventricular hemorrhage, intracerebral hematoma and acute and chronic subdural hematoma), hydrocephalus, intracranial hypertension, intracranial infectious diseases and various cranial hematomas. It is an effective method for drainage therapy and drug infusion after brain surgery. Affected by traditional technical concepts, for a long time, brain drainage tubes routinely used in clinical practice have shortcomings such as narrow tube diameter, blunt or open blind end, and poor tube wall elasticity.

AI Technical Summary

Problems solved by technology

Affected by traditional technical concepts, for a long time, brain drainage tubes routinely used in clinical practice have shortcomings such as narrow tube diameter, blunt blind end or open type, and poor tube wall elasticity.

These shortcomings of the drainage tube seriously affect the therapeutic effect: (1) the blind end of the blunt or open type drainage tube is very easy to damage the brain tissue, nerves and blood vessels during the puncture; Or the adhesion or blockage of bloody drainage material leads to drainage failure; (3) The elasticity of the tube wall directly affects the drainage effect, etc.

Therefore, the traditional brain drainage device can no longer be adapted and used as a drainage treatment in modern neurosurgery.
