Description
Technical Field
The utility model relates to a disposable connection protection device of a peritoneal dialysis catheter and an injector.
Background
Over 70 million patients in China are receiving renal replacement therapy, and the number of patients undergoing peritoneal dialysis is 86644, which also increases year by year at a 10% -12% annual rate of increase. The peritoneal dialysis treatment technology is mature day by day, but the peritoneal dialysis tube displacement occurs at a probability of 10% -22%, which is represented by reduced outflow volume of peritoneal dialysis, slow down or stop of flow speed, improper catheter position or displacement from true pelvis is visible in abdominal X-ray examination, the dialysis is seriously affected, and the pain and burden of patients are aggravated. The most effective treatment operation in clinic is injector pressurization impact reset, the method makes the liquid in the tube cavity generate vortex by the way of injector pressurization and perfusion, can increase the impact effect on the conduit wall to wash away the small bubbles or attachments on the inner wall of the conduit, prevent the conduit from floating or blocking, and the instantaneous action force of pressurization can make the conduit generate the extension force of straightening, and the conduit is reset by the action of gravity and the opening of the conduit pointing to the bottom of the abdominal cavity. The success rate of the compression impact reduction is as high as 95%, and the advantages of simplicity, economy, no wound and the like are the most common reduction means after the catheter is clinically displaced.
However, the current syringe pressure impact operation process has great inconvenience, firstly, the aseptic requirement of the operation process is extremely high because the peritoneal dialysis catheter is directly communicated with the abdominal cavity, and the aseptic treatment of the current operation is very limited, and after the titanium joint of the peritoneal dialysis catheter is thoroughly sterilized and exposed by an operation nurse, the titanium joint is only wrapped by gauze and is always held by hand, and the method cannot guarantee the absolute sterility of the titanium joint in the operation process. Secondly, the nurse needs to hold the titanium joint with gauze all the time in the operation process, and the activity of drawing the injection is very limited, so other nurses are often needed to assist from side, and the manpower resource is wasted. Moreover, nurse is very big with the in-process resistance of syringe pressurization bolus, and nurse one hand need hold the gauze and connect with parcel titanium, and the while other hand needs to push with the syringe pressurization bolus, does not accord with human mechanics standard, has greatly reduced the impact effect, and because the gauze is too big in the operation process, often shields the field of vision, leads to the easy slippage of operation process, then arouses contact infection, and serious person can lead to parcel peritonitis and terminate the peritoneal dialysis treatment, even the operation.
