[0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing a concentration similar to that of the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.

[0003] There is a problem in clinical practice. If the patient cannot use heparin during dialysis, blood clots are likely to form in the dialyzer and dialysis tubing.

The upper pot cover 11, the lower pot cover 12 and the intravenous pot body 1 can be fixed by threaded connection or thermal bonding, and the lower pot cover 12 and the intravenous pot body 1 can also be designed as an integral whole. The intravenous pot body 1, the upper pot cover 11 and the lower pot cover 12 form a sealed chamber, and a filter screen 14 is arranged in each intravenous pot body 1. A boss ring 15 for mounting the filter screen 14 is arranged on the inner wall of the intravenous pot body 1. The filter screen 14 is interference fit or overfit with the inner wall of the intravenous pot body 1. The shape of the filter screen 14 can be flat, or the shape of the filter screen 14 can be designed to be truncated or conical, so that the filtering area of ​​the filter screen 14 can be further increased, so that the filter screen 14 has a higher filtering efficiency and service life. The upper pot cover 11 is provided with an upper connecting pipe 111, and the upper connecting pipe 111 is connected with an upper passage switching assembly 2, and the upper passage switching assembly 2 is used to switch the liquid inlet passages of the two intravenous pot bodies 1. The lower pot cover 12 is provided with a lower connecting pipe 121, and the lower connecting pipe 121 is connected with a lower passage switching assembly 3, and the intravenous pot body 1 is used to switch the liquid outlet passages of the two intravenous pot bodies 1.

[0029] like Figure 4 , 5As shown in Figure 6, the upper passage switching assembly 2 includes an upper barrel body 21, a lower barrel body 22, an upper rubber plug 23 and a lower rubber plug 24. The upper barrel body 21 and the lower barrel body 22 are plugged together to form a cylindrical accommodating chamber. The upper barrel body 21 and the lower barrel body 22 are rotatably connected. The upper barrel body 21 is plugged into the lower barrel body 22. The lower barrel body 22 can rotate relative to the upper barrel body 21. The upper rubber plug 23 is fixedly connected to the upper barrel body 21, and the lower rubber plug 24 is fixedly connected to the lower barrel body 22. The upper rubber plug 23 and the lower rubber plug 24 are tightly fitted. The upper rubber plug 23 and the lower rubber plug 24 are arranged in the cylindrical accommodating chamber.

When the blood inside the working venous pot main body 1 coagulates and the blood cannot circulate, the pipeline is switched to another venous pot main body 1 through the upper pathway switching component 2 and the lower pathway switching component 3. First, switch the pipeline of the lower passage switching assembly 3, and drive the two intravenous pot bodies 1 to move and rotate, so that the upper barrel body 21 in the lower passage switching assembly 3 on the lower side rotates relative to the lower barrel body 22, and rotates until it is aligned with the arrow 212 and another aligned convex line 221. At this time, it means that the upper through hole 231 of the upper rubber plug 23 in the lower passage switching assembly 3 has been connected with the lower through hole 24 in the lower rubber plug 24, that is, the lower side of the liquid pipe 211 is connected with the intravenous pot body 1, indicating that the pipeline switching of the lower passage switching assembly 3 of the inoperative intravenous pot body 1 is completed, and the rotation can be stopped. Similarly, the upper passage switching assembly 2 above the intravenous pot body 1 to be operated can be performed in the same way, so that the upper connecting pipe 111 of the intravenous pot body 1 to be operated is connected with the liquid pipe 211, and the operation switching of the intravenous pot body 1 is completed.
