The fluid replacement bag 1 is used to store dialysis fluid. A dialysis fluid inlet assembly is provided on the fluid replacement bag 1. A waste liquid discharge assembly is fixedly connected to one side of the surface of the dialysis fluid inlet assembly. The dialysis fluid inlet assembly and the waste liquid discharge assembly are in communication. A collector is inserted into the bottom surface of the waste liquid discharge assembly. A stabilizer is fixedly connected to the lateral surface of the collector. The stabilizer includes a first connecting rope 2, a clamping block 3, a second connecting rope 4, and a clasp 5. One end of the first connecting rope 2 is fixedly connected to one side of the surface of the collector. The other end of the first connecting rope 2 is fixedly connected to the clamping block 3. The other side of the surface of the collector is fixedly connected to the second connecting rope 4. One end of the second connecting rope 4 is fixedly connected to the clasp 5. The stabilizer is used to restrict the collector to a predetermined position. When the patient needs to replace the fluid, the fluid replacement bag 1 is hung on the infusion stand. The dialysis fluid inlet assembly is connected in communication with the peritoneal dialysis catheter prepositioned in the patient's body. The dialysis fluid inlet assembly is opened. The dialysis fluid in the fluid replacement bag 1 gradually flows into the peritoneum of the patient's body for peritoneal dialysis. After the peritoneal dialysis is completed, the dialysis fluid inlet assembly is closed, and the waste liquid discharge assembly is opened. The waste liquid after the peritoneal dialysis is discharged into the collector.
[0030] Further, in order to improve the stability of the collector, the collector can be placed beside the bed. The clamping block 3 is clamped into the interior of the clasp 5, so that the collector is fixed to the guardrail or railing of the hospital bed. Even if the patient moves slightly during the fluid replacement, the collector is not easy to fall off. The stability of the collector during the fluid replacement process is improved. The patient's body position is not easy to deviate or the body is not easy to shake during the fluid replacement process, so that the collector does not slide off and the liquid does not spill to the ground, thereby improving the fluid replacement efficiency.

After the liquid is replaced, the first medical clamp 7 is opened, the replaced liquid flows into the first connecting pipe 6, and then flows into the sampling bottle 8. After a certain amount of liquid is collected, the first medical clamp 7 is closed to prevent the liquid from flowing into the sampling bottle 8, and the sampling is completed. The sampled liquid can be conveniently subjected to testing and other operations, thereby achieving the effect of convenient sampling, avoiding the situation that the replaced liquid is difficult to take out, and affecting the testing efficiency.
[0032] The top of the liquid replacement bag 1 is fixedly connected with a medicine adding device.

[0039] The peritoneal dialysis fluid replacement device of the embodiment can be placed on the bedside when the patient needs to replace the fluid, and then the clamping block 3 is clamped into the inner part of the buckle 5 to fix the collector on the guardrail or the railing of the bed. Even if the patient moves slightly during the fluid replacement, the collector is not easy to fall off, which improves the stability of the collector during the fluid replacement process and avoids the situation that the patient's body position deviates or the body easily shakes during the fluid replacement process, causing the collector to slide off and the liquid to spill to the ground, affecting the fluid replacement efficiency. After the fluid replacement, the first medical clamp 7 is opened, the waste liquid after the peritoneal dialysis flows into the inner part of the first connecting pipe 6, and then the liquid flows from the first connecting pipe 6 to the sampling bottle 8. After a certain amount is collected, the first medical clamp 7 is closed to prevent the liquid from entering the sampling bottle 8, and the sampling is completed. The liquid after sampling can be easily subjected to testing and other operations, which facilitates sampling and avoids the situation that testing generally needs to sample and detect the liquid after the fluid replacement, and the liquid after the fluid replacement is difficult to take out, affecting the testing efficiency. During the fluid replacement, the connector 11 is connected to the dialysis pipeline in the body.

After the second medical clamp 10 is closed, the third medical clamp 13 is opened, the waste liquid in the body after the peritoneal dialysis flows into the third connecting pipe 12, and then flows into the fluid replacement collection bag 15 to complete the fluid replacement. After the third connecting pipe 12 is inserted into the limiting ring 14, the toxin in the patient's body can flow into the fluid replacement collection bag 15 through the third connecting pipe 12 to prevent the toxin from spilling to the ground and polluting the indoor environment. The bottom of the medicine inlet 17 is inserted into the fourth connecting pipe 16, and the top of the medicine inlet 17 expands outward to facilitate the addition of medicine and the mixing of different liquid medicines. The transparent window 18 can be more intuitive to observe the amount of toxin collected in the fluid replacement collection bag 15, and the numerical value mark 19 can clearly know the specific collection value of the toxin. The fluid replacement device can be plastic or other materials that can be used for medical treatment, without limitation. The fluid replacement collection bag 15 can be fixed on the waist, and the fluid replacement bag 1 can be held by the patient or placed at the required location. The weight of the collector of the present application is not large, and after being tied at the predetermined position, the first connecting rope 2 and the second connecting rope 4 or the collector is hung at the predetermined position, which does not affect the smoothness of the waste liquid drainage. The first medical clamp 7, the second medical clamp 10, and the third medical clamp 13 are all medical clamps in the prior art. The connector 11 on the connecting pipe 9 is used to connect the peritoneal dialysis catheter 20 in the abdominal cavity to realize the fluid replacement. By opening different medical clamps, single-channel liquid flow can be realized. The negative pressure of the bottle for collecting the waste liquid can be assisted by external equipment. When the present application is used, the fluid replacement bag 1 can be removed first to mix the medicine, and then used. The limiting ring 14 is used for clamping with the third connecting pipe 12.
