Double-cavity peritoneal dialysis built-in tube

The utility model relates to a double-cavity peritoneal dialysis built-in tube which comprises a tube body and a dacron sleeve adhered to the tube body. The double-cavity peritoneal dialysis built-in tube is characterized in that two cavities which are parallel to each other in the axial direction are formed in the tube body; one cavity is a large cavity for drainage and perfusion, and the tube wall, corresponding to the position 10cm away from the tail end of a peritoneum, of one side of the large cavity of the tube body is provided with a plurality of side holes used for increasing dialysis flow; the other cavity is a small cavity with the front end being of a blind end structure, the rear end of the small cavity is communicated with a guide wire inserting opening, and a guide wire used for adjusting the position of the dialysis built-in tube is inserted in the small cavity. The double-cavity peritoneal dialysis built-in tube has the advantages that when a dialysis tube makes displacement to make dialysis be unsmooth clinically, patients or doctors can insert the guide wire into the small cavity of the dialysis built-in tube so that the position of the dialysis built-in tube can be adjusted slightly, the peritoneal dialysis tube is guaranteed to be smooth, and thus peritoneal dialysis treatment can be conducted smoothly; the pains of the patients and the trouble of operators can be reduced, using safety is improved, surgical risks are also lowered, and convenience is brought to operation of medical staff.
