Abstract

The invention relates to the technical field of medical appliances and discloses a cerebrospinal fluid drainage tube and a cerebrospinal fluid drainage device. The cerebrospinal fluid drainage tube isused for solving the technical problem of related technologies that rise of intracranial pressure is easily caused during cerebrospinal medicine injection drainage. The cerebrospinal fluid drainage tube comprises a main tube, wherein a medicine injection chamber, a drainage chamber and a diversion chamber are arranged in the main tube in a spaced manner, the main tube comprises a drainage end anda connecting end, the drainage end is provided with a medicine injection hole communicating with the medicine injection chamber and a drain hole communicating with the drainage chamber, elastic support parts communicating with the diversion chamber are arranged on the main tube close to positions of the medicine injection hole and the drain hole, and diameters of the elastic support parts after charged inflation are greater than a tube diameter of the main tube. The cerebrospinal fluid drainage tube and the cerebrospinal fluid drainage device can be applied to cerebral surgical operations.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cerebrospinal fluid drainage tube and a cerebrospinal fluid drainage device. Background technique [0002] External drainage of cerebrospinal fluid is one of the most commonly used clinical treatment techniques in neurosurgery. It specifically refers to the continuous drainage of cerebrospinal fluid in the ventricle or lumbar cistern to the closed system outside the body, including ventricular drainage and lumbar cistern drainage. The main purposes of external ventricular drainage include release of contaminated cerebrospinal fluid, monitoring and control of intracranial pressure, and administration of necessary medications. [0003] Among them, in the clinical practice of drug treatment, the drug needs to be injected into the brain first, and then sucked out after the drug is absorbed and reacted. In related technologies, a double-lumen tube with a drainage cavity and...
