A comprehensive nursing intervention device for cerebrospinal fluid drainage in lumbar pool

Abstract

The invention discloses a comprehensive nursing intervention device for cerebrospinal fluid drainage in lumbar cistern, which comprises a back patch, a drainage tube assembly and an outlet assembly. The drainage tube assembly includes a drainage tube and an introduction needle. The introduction needle is arranged at one end of the drainage tube, and the introduction needle is inserted into the lumbar pool. The other end of the drainage tube is connected to the extraction assembly. Liquid bag, the top of the inner tube is connected to the drainage tube, the inner tube near the bottom is provided with a diaphragm, the bottom of the inner tube is nested with the outer tube, the bottom of the outer tube is closed, and there are a number of flow holes on the side of the lower end of the inner tube, the flow holes allow the membrane The space under the diaphragm is connected to the outer tube, and the outer tube is filled with pressure distribution fluid, which is in contact with the lower surface of the diaphragm. One end of the discharge pipe is inserted into the inner pipe from the side and extends downward to contact the upper surface of the diaphragm. A through hole facing the diaphragm is provided, and the other end of the discharge pipe is connected to the liquid collection bag.

Description

technical field [0001] The invention relates to the field of spinal fluid drainage, in particular to a comprehensive nursing intervention device for lumbar cerebrospinal fluid drainage. Background technique [0002] Cerebrospinal fluid drainage is often used in intraoperative and postoperative auxiliary operations of brain surgery. Its purpose is to reduce intracranial pressure and create conditions for further brain surgery or postoperative recovery. Cerebrospinal fluid drainage can also promote the secretion of cerebrospinal fluid, allowing the drained cerebrospinal fluid to take away possible bacteria and repair the meninges. The lumbar cistern is connected to the brain in the human body. Draining cerebrospinal fluid from the lumbar cistern is much less risky than directly draining from the head. more and more. [0003] In the prior art, most cerebrospinal fluid drainage devices simply adjust the drainage pressure by raising and lowering the height of the drainage tube....

AI Technical Summary

Problems solved by technology

[0003] In the prior art, most cerebrospinal fluid drainage devices simply adjust the drainage pressure by raising and lowering the height of the drainage tube. For example, the patent application number CN201720668251.6 only uses a lifting bracket to lift a drainage bag for drainage, drainage flow and speed It is set by the height of the drainage tube, and there are also some mechanical pressure regulation methods, such as the patent application number CN201711287381.6, which defines the cerebrospinal fluid outflow pressure by spring preload. These methods are either inaccurate in pressure regulation, or the threshold value The pressure cannot be changed, and the applicability is not high

[0004] In the prior art, the stability of the drainage tube is not considered. Basically, care is taken during use to prevent the drainage tube from bending, especially the section of the tube just out of the human body.
