Closed in-vitro ventricular drainage apparatus

Abstract

The invention relates to a closed in-vitro ventricular drainage apparatus, which comprises two pipelines which are bent in the form of right angles and an analyzer which is arranged outside the pipelines, wherein the two pipelines, which are bent in the form of the right angles, include a first pipeline and a second pipeline; a horizontal part of the first pipeline is connected to a cerebrospinal fluid drainage tube which is close to a ventricular end; a vertical part of the second pipeline is connected to a drainage bag; a vertical part of the first pipeline communicates with a horizontal part of the second pipeline; a piston is arranged in the vertical part of the first pipeline; a spring is connected to the lower surface of the piston; the tail end of the spring is fixedly connected to the bottom of the vertical part of the first pipeline; a baroreceptor is arranged at the inner side of the pipe wall of the vertical part of the first pipeline; the baroreceptor is connected to the analyzer; and capillaries are arranged on the horizontal part of the second pipeline. The closed in-vitro ventricular drainage apparatus provided by the invention can overcome shortcomings in the prior art which adopts open drainage and fails to accurately monitor change in intracranial pressure, and the drainage apparatus is capable of conducting pressure monitoring and heart rate monitoring in vitro and is strong in intuitivity.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to the field of extracorporeal drainage technology, intracranial pressure monitoring, and heart rate monitoring, and specifically relates to a closed extracorporeal drainage device for the ventricle. Background technique [0002] Extracorporeal drainage of the lateral ventricle is often used in the treatment of ventricular hemorrhage, intracranial infection and other diseases, and its main purpose is to drain the cerebrospinal fluid or blood accumulated in the ventricle to the outside of the body. Most of the drainage devices currently used clinically use an open drainage tube to connect to the drainage bag, and adjust the drainage volume and intracranial pressure by adjusting the height difference between the outlet of the drainage tube and the ventricle. If the height difference becomes smaller, the CSF drainage increases and the intracranial pressure decreases. However, ...
