Bag body 1 top fixed connection is used for with the liquid injection pipe of dialysis equipment connection liquid inlet pipe 3, and the liquid outlet pipe 4 for with the liquid suction pipe of dialysis equipment connection, and the second sealing cover 5 is set up on liquid inlet pipe 3 and liquid outlet pipe 4. The end of liquid outlet pipe 4 extends to the inner bottom wall of bag body 1, and filter membrane 8 is arranged in liquid outlet pipe 4.
[0019] In the embodiment of the present application, the bag body 1, the first sealing cover 2, the liquid inlet pipe 3 and the liquid outlet pipe 4 are all made of plastic material, and the first sealing cover 2, the liquid inlet pipe 3 and the liquid outlet pipe 4 are fixed on the bag body 1 by plastic welding. The filter membrane 8 is a semi-permeable membrane and can be used to filter impurities in the dialysis solution. The medical staff can connect the liquid inlet pipe 3 and the liquid outlet pipe 4 to the dialysis equipment by opening the two second sealing covers 5. The dialysis equipment can inject the solution into the bag body 1 through the liquid injection pipe, and mix the solution with the dialysis powder to form the dialysis solution, and then the dialysis solution in the bag body 1 can be pumped out through the liquid pumping pipe for use. When the dry powder bag of the present application is used to prepare the dialysis solution, it is not necessary to tear the bag body 1, thereby avoiding the dialysis powder in the bag body 1 from being in contact with impurities and bacteria in the air in a large area, and the preparation quality of the dialysis solution is improved.
[0020] Further, the liquid inlet pipe 3 and the liquid outlet pipe 4 are integrally provided with a boss 6 on the outer wall, and the two second sealing covers 5 are integrally formed with the corresponding two bosses 6 through a connecting portion 7, and the two connecting portions 7 are respectively provided with a plurality of circumferential intervals along the corresponding liquid inlet pipe 3 and liquid outlet pipe 4.
