Drainage device for cerebrospinal fluid leakage after spinal surgery and using method thereof

Abstract

The invention discloses a drainage device for cerebrospinal fluid leakage after a spinal surgery and a using method of the drainage device. The device comprises a transparent sealing cover, a host box, a liquid storage bag and a fan wheel, wherein a sealing plug is arranged on the transparent sealing cover; the transparent sealing cover and the sealing plug are integrally formed; a drainage needleis arranged on the inner side of the transparent sealing cover, and the diameter of the maximum position of the transparent sealing cover is 50 mm; the drainage needle is in interference fit with thesealing plug; a first connecting pipe is installed on one side of the drainage needle; the drainage needle is connected with the first connecting pipe through glue; and an outer connector is arrangedon the first connecting pipe. The device is provided with the transparent sealing cover, so that a wound is protected and sealed, external bacterial infection during drainage is avoided, the sterileenvironment is guaranteed and infection is avoided. The device is provided with a plurality of detection devices, so that the effect of detecting the flow speed, the pressure and the PH value is achieved, meanwhile, the device has an alarm function, the operation intelligence degree of the device is high, and meanwhile, the drainage process is more stable and safer.

Description

technical field [0001] The invention relates to the field of spinal surgery, in particular to a drainage device for cerebrospinal fluid leakage after spinal surgery and a usage method. Background technique [0002] In clinical practice, external cerebrospinal fluid drainage (also known as lumbar cistern drainage) is a safe, effective, and minimally invasive method for treating neurosurgical diseases such as cerebrospinal fluid leakage, intracranial infection, and subarachnoid hemorrhage. It is suitable for the treatment of severe craniocerebral injury postoperative and traumatic subarachnoid hemorrhage, various intractable cerebrospinal fluid otorrhea, rhinorrhea, and incision leakage, intracranial infection, intractable subcutaneous effusion, and communicating hydrocephalus. Good curative effect. During cerebrospinal fluid drainage, how to accurately control the drainage speed and drainage volume of cerebrospinal fluid is a difficult problem. The traditional method is to ad...

It is suitable for the treatment of severe craniocerebral injury postoperative and traumatic subarachnoid hemorrhage, various intractable cerebrospinal fluid otorrhea, rhinorrhea, and incision leakage, intracranial infection, intractable subcutaneous effusion, and communicating hydrocephalus. Good curative effect. During cerebrospinal fluid drainage, how to accurately control the drainage speed and drainage volume of cerebrospinal fluid is a difficult problem. The traditional method is to adjust the drainage volume by adjusting the relative height of the drainage tube, but it is difficult to accurately control the height, which may easily cause excessive drainage or Excessive drainage of cerebrospinal fluid and rapid drainage of cerebrospinal fluid will lead to a sharp drop in intracranial pressure, which can lead to serious complications such as brain herniation; Intracranial pressure may change in a curve, and ordinary drainage devices cannot effectively detect and control pressure changes. At the same time, because the content of cerebrospinal fluid is not much, intracranial hemorrhage may also occur, which requires experienced doctors to diagnose. At the same time, it increases the surgical pressure on the attending physician
