Fixing device for external ventricular drainage

Abstract

A limiting buffer assembly is installed on the top face of a bottom plate, the bottom end of an internal thread supporting pipe is movably sleeved with a supporting plate, an edge spring is welded to the middle of the top face of an arc-shaped sliding block, an annular bottom groove is formed in the position, corresponding to the end of a rotating plate, of a sleeve, and threading rings are evenly welded to the middle of an S-shaped spring plate. A drainage bottle limiting assembly is arranged between the rotating plate and the supporting plate, the ejector rod is connected with a drainage tube protection assembly, and a disinfection anti-disengaging assembly is installed at one end of a protection tube. A drainage bottle is clamped and fixed through the rotating plate after being placed on the top face of the supporting plate, and the drainage tube is guided and limited through an S-shaped spring plate and a threading ring; the S-shaped spring plate deforms to be matched with the bending shape change when the drainage tube is pulled, the drainage tube is prevented from being bent and blocked, the supporting plate slides along the internal thread supporting tube for buffering, the influence of the fixing device on the position, connected with the human body, of the drainage tube is reduced, and therefore the device is more comfortable to use and better in safety.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixing device for external ventricular drainage. Background technique [0002] Continuous ventricle drainage is a medical operation, which is suitable for patients with severe intracranial pressure such as intraventricular or posterior fossa space-occupying lesions, frequent vomiting, physical weakness, and vision loss. Continuous ventricle drainage should be performed first, and then angiography and imaging should be performed after the condition improves. Surgery requires drainage for several days after the operation. The drainage fixture is a device used to fix the drainage device. Its function is to prevent the drainage device from toppling over and the pipeline to be entangled, and to assist drainage. [0003] However, when the current drainage fixture is used, the vibration and the displacement of the fixture will pull the drainage tube to move, which will easily ...
