External ventricular drainage device

Abstract

The external ventricular drainage apparatus comprises a drainage tube, one end of the drainage tube is sealed, the other end of the drainage tube is detachably communicated with an adsorption device, the adsorption device is communicated with a collection device, and an anti-blocking assembly is arranged between the adsorption device and the collection device; a plurality of drainage holes are circumferentially formed in the outer wall of the end, away from the adsorption device, of the drainage tube at equal intervals and communicate with an inner cavity of the drainage tube; a plurality of medicine injection cavities are formed in the drainage tube in the circumferential direction at equal intervals, the axes of the medicine injection cavities are parallel to the axis of the drainage tube, a plurality of medicine adding openings are formed in the outer wall of the drainage tube, and the medicine adding openings and the drainage holes are arranged at intervals; switch controllers are arranged between the drainage tube and the adsorption device and between the adsorption device and the anti-blocking assembly. The multi-cavity design is adopted, besides the drainage cavity in the center of the drainage tube, the multiple independent medicine injection cavities are further arranged, medicine injection and drainage are separated, and all medicine can be accurately delivered into the ventricle.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an extra-ventricular drainage device. Background technique [0002] Intracranial infection is a common complication in neurosurgery. If it cannot be treated in time and effectively, patients will suffer from epilepsy, paralysis, dementia and other sequelae, and even lead to death in severe cases. According to relevant studies, the infection rate of patients after neurosurgery is 2% to 8%. Intracranial infections usually require intraventricular antibiotic injection through a drain to suppress the infection. Intracerebral hemorrhage patients also require intracranial injection of urokinase to accelerate clot dissolution. [0003] Ventricular drainage is a technique in which the front end of a drainage catheter with several lateral holes is placed in the ventricle, and a sterile drainage bag is attached to the end to drain the cerebrospinal fluid out of the body. It i...

Problems solved by technology

Usually, as the drainage time increases, the device will block the tube, which may lead to intracranial hypertension and brain herniation, endangering the patient's life
