A kind of airtight extracorporeal drainage device of ventricle

Abstract

The invention relates to a closed extracorporeal drainage device of the ventricle, which comprises two right-angled pipes and an analyzer arranged outside the pipes. The two right-angled pipes are respectively a first pipe and a second pipe. The horizontal part is connected with the cerebrospinal fluid drainage tube close to the end of the ventricle, the vertical part of the second pipe is connected with the drainage bag, the vertical part of the first pipe is connected with the horizontal part of the second pipe; the vertical part of the first pipe is provided with The piston is connected with a spring under the piston, and the end of the spring is affixed to the bottom of the vertical part of the first pipeline; the inner side of the vertical part of the first pipeline is provided with a pressure sensor, and the pressure sensor is connected to the analyzer; the second pipeline The horizontal section is provided with capillary channels. The invention overcomes the defects of open drainage and inability to accurately monitor changes in intracranial pressure in the prior art, is a closed extracorporeal drainage device for the ventricle, can monitor pressure and heart rate outside the body, and has strong intuitiveness.

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, ...
