Abstract:
The consensus has been reached on the benefits of surgical drainage. However, catheter-related blockage and retrograde infection remain bottleneck problems in the treatment process. To this end, with Huashan Hospital, Fudan University, as the main inventors, a drainage tube dredging umbrella and anti-retrograde infection kit have been designed and applied for the national utility model patent (patent number: ZL 2023 2 1300036.2). The main body of the kit consists of a catheter dredging umbrella, drainage tube, and drainage bag. Several isolation layers are installed in the drainage bag to form a maze structure and a reflux valve is added, thereby increasing the distance and resistance of liquid reflux, greatly reducing the possibility of liquid reflux entering the drainage tube, so as to reduce the risk of retrograde infection through physical means. When the drainage tube is blocked, the drainage tube and joint tube of the drainage bag can be separated, the unblocking umbrella can be inserted into the blockage through the guide wire, the cannula can be inserted along the guide wire, the guide wire is pulled to release the dredging umbrella in the contraction state, and the dredging umbrella can be pulled back in the expansion state until the blockage is removed from the drainage tube. The operating procedure is standardized and simple. While preventing retrograde infection (anti-retrograde infection kit), the catheter dredging umbrella could effectively address the issue of catheter blockage. It has certain clinical promotion and application value.
