The peritoneal dialysis doll, used for training patients or medical personnel in peritoneal dialysis exchanges, includes a torso that is hollow and holds a fluid reservoir. A peritoneal dialysis catheter is inserted within an opening in the torso, which serves as the exit site of the catheter, and is connected to the fluid reservoir. The catheter is attached to a transfer set that includes a valve connected to the transfer set to control the flow of dialysis solution into or out of the catheter. A tubing connector includes a Luer adapter and a transfer set connector for attaching the transfer set to the catheter with Luer fittings. The fluid reservoir is retained within the doll by fitting the reservoir inside the torso through a rear opening in the doll.
