Visualized Antimicrobial Drainage Catheter

Technical Field

The utility model relates to the technical field of cerebrospinal fluid drainage, in particular to a visualized antibacterial drainage catheter.

Background Art

Extraventricular drainage of cerebrospinal fluid is one of the most commonly used treatment techniques in neurosurgery. It specifically refers to the continuous drainage of cerebrospinal fluid in the ventricles or lumbar cistern into an external closed system, including extraventricular drainage and extralumbar drainage. The main purposes of extraventricular drainage include releasing contaminated cerebrospinal fluid, monitoring and controlling intracranial pressure, and conducting necessary drug treatment.

Among them, in clinical drug treatment, the drug needs to be injected into the skull first, and then sucked out after the drug absorption reaction. In related technologies, a double-lumen tube with a drainage cavity and an injection cavity, or a single-tube single-lumen drainage tube combined with a single-lumen single-tube injection tube is usually used for treatment.

However, when using the above-mentioned drug injection drainage tube, in order to prevent the drug solution from being directly drained out of the body before the absorption reaction, it is necessary to clamp the drainage tube for a period of time after the drug is injected into the skull, and then open the drainage after the drug solution reacts completely. When the existing drainage catheter is actually draining, there are a lot of viscous lesions in the effusion, which can easily block the entire drainage tube, making it impossible to clearly observe the effusion in the drainage, whether there is blockage, etc., and when the drainage catheter is draining, there is also a risk of backflow of the effusion drained into the liquid storage bag, thereby increasing the risk of infection.

In the existing practice of draining the liquid medicine in the lumbar cistern, since the drainage tube is a single-tube structure, there are still foreign matter accumulated in the liquid medicine, and the accumulated foreign matter is in a viscous state. When it is introduced from the drainage tube, it is easy to cause the drainage tube to be blocked. At this time, the drainage tube needs to be led out and introduced into the flushing tube, and the pipeline needs to be repeatedly flushed to avoid the next blockage. The above repeated extraction operation makes it easy for foreign bacteria to enter the lumbar cistern again. In this regard, the utility model provides a visual antibacterial drainage catheter, which can effectively solve the drainage problem. In order to solve the problem of tube blockage, it is convenient to observe the condition of the drainage tube so that the drainage is completely separated from the outside world to avoid reinfection caused by the entry of bacteria. The visualized antibacterial drainage catheter includes: a drainage tube 10, extending into the lumbar cistern; a drainage ball 20, arranged on the outer wall of the drainage tube 10, for implementing the blockage of the bladder and urethra; a first transparent cavity 30, arranged on the drainage tube 10; a guide tube 50, connected to the drainage tube 10; a second transparent cavity 40, arranged on the guide tube 50; and a receiving bottle 70, connected to the guide tube 50.

In one embodiment, when the visualized antibacterial drainage catheter is actually used, the drainage tube 10 and the drainage ball 20 are introduced into the lumbar cistern at the opening position of the patient's lumbar cistern, and the drainage ball 20 is expanded by introducing gas to achieve the sealing of the craniotomy position. The medicine liquid and flocs in the lumbar cistern are introduced from the drainage tube 10 into the first transparent cavity 30, and then introduced into the second transparent cavity 40 through the gravity tube 10, and then exported to the receiving bottle 70 through the outlet tube 50. By observing the number of drops in the first transparent cavity 30 and the second transparent cavity 40, it can be determined whether the drainage tube 10 is blocked, and the entire conductive pipeline is a closed pipeline, and the accumulated fluid is discharged through the receiving bottle 70 to avoid infection problems caused by the backflow of the accumulated fluid in the pipeline.

Furthermore, in actual application, once the pipeline is clogged, the pipeline can be flushed by pressing the first transparent cavity 30 and the second transparent cavity 40, thereby effectively clearing the clogged point of the pipeline.
