A kind of pleural drainage catheter

Abstract

The utility model relates to a pleural cavity flushing and drainage catheter, which belongs to medical equipment and is suitable for treating patients with empyema. Irrigation and drainage are the most basic treatment methods for empyema. Manual irrigation and drainage through a single chest tube makes the chest cavity susceptible to external infection; short-term bolus injection of irrigation fluid damages the pleura and spreads bacteria; repeated manual operations every day cause pain for the patient. The clinical workload is heavy. The catheterization operation of the present invention is simple; chest flushing and drainage can be performed at the same time, and the catheter can be removed when flushing is not required to continue closed chest drainage; the pipeline is always sealed and one-way drainage to avoid chest infection; sustainable chest flushing and drainage, High clinical curative effect, small workload; suitable for abscess cavities of different sizes.

Description

Technical field [0001] The invention relates to a medical device, in particular to a thoracic irrigation and drainage catheter suitable for treating patients with empyema. Background technique [0002] Drainage is the most basic treatment method for empyema. Closed drainage with intercostal catheterization is the most commonly used, and repeated pleural irrigation has a significant effect. At present, multiple irrigation and drainage are performed through a single chest tube. When flushing the chest cavity, the catheter can only be temporarily disconnected. The irrigation fluid is repeatedly injected and sucked from the same chest tube, which inevitably communicates with the outside world, and the drainage fluid has already adhered to the chest cavity. The pus moss on the inner wall of the tube will re-enter the chest cavity, increasing the chance of infection. The short-term bolus injection of flushing solution will increase the local pleural pressure, which is not conduci...

AI Technical Summary

Problems solved by technology

The short-term bolus injection of flushing solution will cause high local pleural pressure, which is not conducive to local pleural repair, and may even cause bacterial dissemination, especially for patients with bronchopleural fistula

Repeated manual operations every day not only cause pain for patients, but also increase clinical workload, so it becomes a big confusion for clinicians
