Description

A peritoneal dialysis system

technical field

The utility model relates to the field of peritoneal dialysis, in particular to a peritoneal dialysis 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 system includes a peritoneal dialysis supervisor, a peritoneal dialysis tube, and a waste liquid pipe. The peritoneal dialysis supervisor is connected with the peritoneal dialysis tube and the waste liquid pipe respectively. The end of the 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 Dialysate, during dialysis exchange, the dialysis waste liquid of the peritoneal cavity is first flowed into the waste liquid bag along the peritoneal dialysis main pipe and the waste liquid pipe by 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 system is disassembled and discarded during the interval of the peritoneal dialysis solution, so as to facilitate the patient's activities.

When the peritoneal dialysis fluid is input into the peritoneal cavity, the pressure of the abdominal cavity will increase. If too much peritoneal dialysis fluid is input, the pressure of the abdominal cavity will be too high, resulting in abdominal discomfort, compression of the heart and lungs, and even sleep disorders. The size of the abdominal cavity of each patient is also They are not the same, after inputting the same amount of peritoneal dialysis fluid, the change of abdominal pressure of each patient is also different. The degree of change determines the input volume of peritoneal dialysis fluid. Since the existing peritoneal dialysis system does not have a corresponding peritoneal pressure detection device, the following methods are generally used to measure the peritoneal pressure. When the dialysis is stopped, the peritoneal dialysis system is separated, connected to the infusion tube, and the other end of the infusion tube is opened. Highly measured intra-abdominal pressure, this method is cumbersome to operate, requires interruption of dialysis, and the open end will increase the chance of infection.

Detailed ways

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

As shown in Figure 1, the peritoneal dialysis system includes a peritoneal dialysis supervisor 1, a peritoneal dialysis tube 2, and a waste liquid pipe 3. The end is connected with a peritoneal dialysis bag 4, the peritoneal dialysis tube 2 is provided with a peritoneal dialysis circuit 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 circuit switch 7. The peritoneal dialysis main pipe 1 or the waste liquid pipe 3 is provided with a pressure detection device for detecting the pressure of the liquid in the pipe. The use process of the peritoneal dialysis 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 liquid along the peritoneal dialysis main pipe 1 and waste liquid pipe 3 by gravity Bag 6, then, open the peritoneal dialysis circuit switch 5, close the waste liquid circuit switch 7, and fresh dialysate is input in the peritoneal cavity by the peritoneal dialysis tube 2, the peritoneal dialysis main pipe 1. Since the pressure detection device is set on the peritoneal dialysis main pipe 1 or the waste liquid pipe 3, during the peritoneal dialysis process, the liquid pressure in the pipe can be detected, thereby indirectly knowing the pressure change in the abdominal cavity. According to the pressure change in the peritoneal cavity, The medical staff can easily determine the appropriate amount of dialysate input, so that the patient's abdominal pressure can be kept at an appropriate value, and the pressure in the abdominal cavity can be avoided. Reduce the chance of patients being infected.

In the above implementation process, the pressure detection device can adopt various existing pressure detection tools, such as a hydraulic tester, a pressure gauge, etc., as a preferred mode: the pressure detection device includes a pressure sensor 8, a processor 9. Display 11 , the pressure sensor 8 is arranged on the outer wall of the peritoneal dialysis main pipe 1 or the waste liquid pipe 3 , the pressure sensor 8 and the display 11 are electrically connected to the processor 9 respectively. Since the pressure of the dialysis waste liquid changes with the change of the abdominal cavity pressure, and the pressure change of the dialysis waste liquid will cause the wall of the peritoneal dialysis main pipe 1 or the waste liquid pipe 3 to expand or contract, the expansion and contraction will be detected by the pressure sensor 8 The change state of the system is recorded and transmitted to the processor 9, and after being processed by the processor 9, it is displayed on the display 11 to facilitate the monitoring of the medical personnel. This pressure detection device can detect the pressure without contacting the peritoneal dialysis fluid, and can effectively The pollution of dialysis waste liquid is avoided, the chance of patients being infected is reduced, and the pressure detection device is also kept clean and hygienic. The shape of the pressure sensor 8 can be various. As a preferred mode, the pressure sensor 8 is annular, and the annular pressure sensor 8 is sleeved on the peritoneal dialysis main pipe 1 or the waste liquid pipe 3. The annular pressure sensor 8 has a larger contact area with the peritoneal dialysis main pipe 1 or the waste liquid pipe 3, and can more accurately measure the pressure of the liquid in the pipe.

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 .
