Description

[Technical field]

[0001] The present invention relates to the technical field of medical appliances, and in particular to a temperature-adjustable cerebral ventricle flushing device. [Background technology]

[0002] Intraventricular hemorrhage, extensive subarachnoid hemorrhage, severe intracranial infection and other common acute and critical diseases in neurosurgery caused by various reasons are serious diseases, with high mortality rate and difficult treatment. Conventional drainage and medication treatment are not ideal. If continuous ventricular irrigation and drainage can be performed, bloody cerebrospinal fluid and inflammatory cerebrospinal fluid can be removed as soon as possible, secondary brain damage can be reduced, mortality and disability rates can be reduced, the success rate of rescue can be improved, the patient's recovery can be promoted, the hospital stay can be shortened, and the patient's family and socioeconomic burden can be reduced. Clinically proven, the temperature of the ventricular irrigation fluid will affect the temperature of the brain environment and affect brain function, causing changes in vital signs. However, the current ventricular irrigation device can only adjust the irrigation flow rate of the irrigation fluid, but cannot adjust the temperature of the irrigation fluid according to the temperature of the patient's head to reduce the impact of the irrigation fluid temperature on the patient's brain environment during ventricular irrigation, which makes it difficult to promote the application of continuous ventricular irrigation and drainage technology in clinical practice. As a result, the current treatment of such diseases is still mainly slow drainage, which prolongs the patient's hospitalization time and significantly increases the patient's family burden. Therefore, there is an urgent need for a temperature-adjustable ventricular flushing device in clinical practice. This ventricular flushing device has very important clinical transformation value. Once put into clinical use, it can greatly shorten the hospitalization time of patients with diseases such as ventricular hemorrhage and reduce the related complications of long-term hospitalization. It has broad clinical application prospects. [Summary of the invention]
