Pleural irrigation drainage catheter

Abstract

The invention belongs to medical instruments and relates to a pleural irrigation drainage catheter. The pleural irrigation drainage catheter is suitable for treating patients with empyema. Irrigation and drainage are basic therapies of empyema; manual irrigation and drainage via a single pleural tube easily causes external infection to the pleural cavity; irrigating liquid is bolus-injected in a short time, the pleural membrane is injured, and germs spread; patients feel pain from repeated manual operations each day, and clinical work is huge. The pleural irrigation drainage catheter is simple to indwell; pleural irrigation and pleural drainage can be simultaneous; the pleural irrigation drainage catheter can be removed when irrigation is not required, and closed pleural drainage is continued; a pipeline is constantly closed, drainage is performed in a single direction, and pleural infection is avoided; pleural irrigation and drainage is continuous, clinical treatment is efficient, and workload is low; the pleural irrigation drainage catheter is suitable for abscess cavities different in size.

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
