Background
Chronic kidney disease is a common and multiple disease. Peritoneal dialysis is an effective home kidney replacement therapy for end-stage renal patients. Wherein the peritoneal dialysis catheter is a lifeline of a peritoneal dialysis patient. Ensuring the smoothness of the peritoneal dialysis catheter is a precondition for ensuring the smooth treatment of the peritoneal dialysis patient. Currently, peritoneal dialysis catheter dysfunction occurs in 4-20% of peritoneal dialysis patients, manifesting as prolonged dialysate drainage or (and) infusion times, which may be accompanied by abnormally reduced dialysate drainage. Peritoneal dialysis catheter displacement, the large omentum coating the end of the peritoneal dialysis catheter, the blockage of the peritoneal dialysis catheter lumen by fibrin clots or blood clots, is a common cause of peritoneal dialysis catheter dysfunction in peritoneal dialysis patients. The use of a syringe to aspirate normal saline or dialysate to pressure flush the peritoneal dialysis catheter is one of the main methods of treating peritoneal dialysis catheter dysfunction.
However, the prior art has the following problems: 1) After the peritoneal dialysis catheter is washed, the peritoneal dialysis catheter can be observed whether to recover to be smooth or not by connecting the dialysis solution Y-type duplex system, if the peritoneal dialysis catheter is still not smooth, the dialysis solution Y-type duplex system is detached, and related treatment is carried out again, so that the operation is complex, the efficiency is lower, and the cost is higher. 2) When the injector interface is connected with the peritoneal dialysis external short tube interface, the air is exposed at the connecting position, so that bacteria are easy to pollute the peritoneal dialysis external short tube interface, and the occurrence risk of peritonitis is possibly increased. 3) The joint of the injector interface and the peritoneal dialysis external short tube interface is not reinforced by a knob. When an operator operates, one hand is required to fix the syringe needle cylinder and the external short tube for peritoneal dialysis, so that the syringe needle cylinder and the external short tube keep the same straight line level and the tightness of the pipeline; the other hand is pressurized to push the syringe piston, which rapidly pushes the fluid into the intra-abdominal section of the peritoneal dialysis catheter. During operation, if the two interfaces are separated carelessly, liquid can be sprayed to the periphery, and the occurrence risk of peritonitis is increased.
Accordingly, it would be desirable to provide a peritoneal dialysis catheter flusher that is simple and safe to operate.
