Description

peritoneal dialysis connection system

technical field

The utility model relates to the field of peritoneal dialysis, in particular to a peritoneal dialysis connection system.

Background technique

Peritoneal dialysis uses the peritoneum as a semi-permeable membrane, and uses gravity to pour the prepared dialysate into the patient's peritoneal cavity through a catheter. In this way, there is a concentration gradient difference of solutes on both sides of the peritoneum, and the solutes on the high concentration side move toward the low concentration. Water moves from the low-osmotic side to the high-osmotic side, and the peritoneal dialysate is constantly replaced to achieve the purpose of removing metabolites and toxic substances in the body and correcting water and electrolyte balance disorders.

At present, the used peritoneal dialysis connection system includes a peritoneal dialysis supervisor, a peritoneal dialysis tube, and a waste liquid tube. The peritoneal dialysis supervisor is connected with the peritoneal dialysis tube and the waste liquid tube respectively. The end of the dialysis tube is connected with a peritoneal dialysis bag, the peritoneal dialysis tube is provided with a peritoneal dialysis tube clamp, the end of the waste liquid tube is connected with a waste liquid bag, and the waste liquid tube is provided with a waste liquid line clip, and the peritoneal dialysis bag is filled with fresh During the dialysis exchange, the dialysis waste liquid in the peritoneal cavity flows into the waste liquid bag along the peritoneal dialysis main pipe and the waste liquid pipe through gravity, and then the fresh dialysate is input into the peritoneal cavity through the peritoneal dialysis pipe and the peritoneal dialysis main pipe , the peritoneal dialysis connection system is removed and discarded during the interval of the peritoneal dialysis solution, so as to facilitate the patient's activities. In the process of peritoneal dialysis, sometimes protein clots in the dialysate, blood clots or omentum in the peritoneal cavity will block the pipeline, causing the flow rate of the dialysate to drop, or even no liquid to flow out, resulting in the failure of peritoneal dialysis. If the flow drop is detected in time, drugs can be used to dissolve the clot to relieve the obstruction. However, the current monitoring of the flow of dialysis waste fluid mainly relies on visual observation, which is neither objective, accurate, nor quantitative. It is impossible to detect the flow drop in time and take timely measures , causing the pipeline to be blocked, resulting in the failure of peritoneal dialysis to proceed smoothly.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the peritoneal dialysis connection system includes a peritoneal dialysis main tube 1, a peritoneal dialysis tube 2, and a waste liquid tube 3. The end of 2 is connected with a peritoneal dialysis bag 4, the peritoneal dialysis tube 2 is provided with a peritoneal dialysis pipeline switch 5, the end of the waste liquid tube 3 is connected with a waste liquid bag 6, and the waste liquid tube 3 is provided with a waste liquid pipeline switch 7. The waste liquid pipe 3 is provided with a flow monitoring device. The use process of the peritoneal dialysis connection system is as follows: first, close the peritoneal dialysis circuit switch 5, open the waste liquid circuit switch 7, and make the dialysis waste liquid in the peritoneal cavity flow into the waste water along the peritoneal dialysis main pipe 1 and the waste liquid pipe 3 by gravity. Liquid bag 6, then, open peritoneal dialysis circuit switch 5, close waste liquid circuit switch 7, and fresh dialysate is input in the peritoneal cavity by peritoneal dialysis tube 2, peritoneal dialysis supervisor 1. Since the flow monitoring device is set on the waste liquid pipe 3, during the peritoneal dialysis process, the liquid flow in the waste liquid pipe 3 can be monitored in real time, so that the medical staff can grasp the change of the liquid flow in the waste liquid pipe 3 in time, Once the flow rate drops, take relevant measures to clear the pipeline in time to avoid pipeline blockage and ensure the smooth progress of peritoneal dialysis.

In the above implementation process, the flow monitoring device can use various existing flow monitoring tools, such as differential pressure flowmeter, electromagnetic flowmeter, etc., as a preferred method: the flow monitoring device includes an ultrasonic flow sensor 8. Processor 9 and display 11, the ultrasonic flow sensor 8 is arranged on the waste liquid pipe 3, the ultrasonic flow sensor 8 and the display 11 are respectively electrically connected to the processor 9, the ultrasonic flow sensor 8 includes a housing 80 and is arranged on the An ultrasonic generator 81 and an ultrasonic receiver 82 are located in the casing 80 and located on both sides of the waste liquid pipe 3 . The flow monitoring device composed of the ultrasonic flow sensor 8, the processor 9 and the display 11 can monitor the flow without contacting the peritoneal dialysis fluid, effectively avoiding the pollution of the dialysis waste liquid, and making the flow monitoring device clean and hygienic.

During the peritoneal dialysis process, sometimes it is necessary to temporarily stop the peritoneal dialysis. At this time, the peritoneal dialysis circuit switch 5 and the waste liquid circuit switch 7 need to be closed. However, in the actual operation process, sometimes the peritoneal dialysis circuit switch 5 is not turned off 1. If the waste liquid pipeline switch 7 is closed tightly, liquid leakage will occur, so that after the peritoneal dialysis is stopped, the dialysate still flows into the peritoneal cavity of the patient, causing unnecessary troubles. Therefore, in order to completely avoid the occurrence of the above situation, the A rotary switch 10 is set on the main tube 1, and the occurrence of liquid leakage can be completely avoided through double switches. At the same time, since the rotary switch 10 set on the primary tube 1 of peritoneal dialysis is closer to the patient's body, the rotary switch 10 can be sterilized , to avoid bacterial infection in patients.

In addition, the peritoneal dialysis pipeline switch 5 and the waste fluid pipeline switch 7 can adopt various existing switches, since the peritoneal dialysis tube 2 and the waste fluid tube 3 are all made of soft materials, Generally, clips are used as the peritoneal dialysis circuit switch 5 and the waste liquid circuit switch 7 .
