The invention discloses a multi-purpose training teaching aid for hematodialysis catheter nursing. The multi-purpose training teaching aid comprises a front piece, a liquid storing connecting pipe IIand a hemodialysis catheter sleeve, wherein a liquid storing bag is arranged on the surface of the front piece, a liquid storing connecting pipe I is inserted on the bottom of the liquid storing bag in a penetrating manner, an adjusting device is fixedly connected to the bottom of the liquid storming connecting pipe I, the bottom of the adjusting device is fixedly connected with the top of the liquid storing connecting pipe II, one end, far away from the adjusting device, on the liquid storing connecting pipe II is fixedly connected with the hemodialysis catheter sleeve in a sealed manner, andthe adjusting device comprises a shell. For the multi-purpose training teaching aid for hematodialysis catheter nursing, through the match use of the structures, the problem that during the practicaluse process, the traditional hemodialysis catheter sleeve effect can not simulate the one-way flowing in different directions of blood in clinic, for example the flowing direction during back pumping, meanwhile, the closing for the flowing channel is not convenient and rapid, so that inconvenience is brought to use, and the teaching quality and efficiency are reduced is solved.
