Comprehensive nursing intervention device for lumboperitoneal shunt cerebrospinal fluid drainage surgery

Abstract

The invention discloses a comprehensive nursing intervention device for a lumboperitoneal shunt cerebrospinal fluid drainage surgery. The comprehensive nursing intervention device comprises a back plaster, a drainage tube assembly and a guiding out assembly, wherein the back plaster is adhered to the waist on the back surface of a human body; the guiding out assembly is used for draining cerebrospinal fluid in a positive pressure form; the drainage tube assembly comprises a drainage tube and a guiding needle; the guiding needle is arranged at one end of the drainage tube, and is inserted intothe lumboperitoneal shunt; the other end of the drainage tube is connected with the guiding out assembly; the guiding out assembly comprises an inner tube, an outer tube, a diaphragm, a discharge tubeand a fluid gathering bag; the top of the inner tube is connected with the drainage tube; the diaphragm is arranged in the tube adjacent to the bottom, of the inner tube; the outer tube is embedded to the bottom of the inner tube in a sleeving manner; the bottom of the outer tube is closed; a plurality of flow passing holes are formed in the lower end side surface of the inner tube, and through the flow passing holes, space below the diaphragm can communicate with the inner part of the outer tube; pressure matching fluid is injected in the outer tube, and is in contact with the lower surfaceof the diaphragm; one end of the discharge tube is inserted into the inner tube from the side surface and extends downwards to be in contact with the upper surface of the diaphragm; and a through holefacing the diaphragm is formed in the bottom end surface of the discharge tube, and the other end of the discharge tube is connected with the fluid gathering 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.
