Description

A double-connected double-bag multi-joint peritoneal dialysis fluid system

technical field

The utility model relates to a peritoneal dialysis fluid system with double-connection, double-bag and multi-joint, which is suitable for patients who have been undergoing peritoneal dialysis for a long time in the field of kidney disease, and is especially suitable for patients whose peritoneal dialysis tube is blocked and needs to be reconnected to the peritoneal dialysis fluid after flushing the tube with heparin saline. In order to avoid the waste of peritoneal dialysis fluid, reduce the economic burden of patients, and reduce the risk of infection caused by improper operation.

Background technique

With the gradual improvement of the level of medical diagnosis and treatment technology, the number of patients diagnosed with uremia is increasing year by year, and patients often face follow-up long-term renal replacement therapy. In the choice of the three types of renal replacement therapy (hemodialysis, peritoneal dialysis and kidney transplantation), peritoneal dialysis has the incomparable convenience of hemodialysis, simple operation, avoidance of blood-borne diseases, stable hemodynamics and resistance to hemodialysis. The protection of residual renal function is obviously superior to that of hemodialysis. Experts and scholars at home and abroad all suggest that peritoneal dialysis is the first choice for patients with no obvious contraindications to peritoneal dialysis. The current traditional peritoneal dialysis process is as follows: first, the patient needs to undergo peritoneal dialysis catheterization to establish a peritoneal dialysis access, and postoperative peritoneal dialysis outer tube can be seen in the patient's abdomen. The dialysate system, whether it is domestic dialysate or imported dialysate, adopts a double-connected double-bag single-joint peritoneal dialysate system. As shown in Figure 1, it consists of a peritoneal dialysis fluid bag 1 containing peritoneal dialysis fluid and a waste fluid bag 2. and two drainage tubes (inlet pipeline 3 and outlet pipeline 4), one end of the two drainage tubes is respectively connected with the peritoneal dialysis fluid bag 1 and the waste fluid bag 2, and the other ends are fused and extended to form a Share the joint, the whole is similar to a "Y"-shaped structure; then, follow the aseptic principle to start the peritoneal dialysis treatment: 1) Clean the table and prepare the necessary items, including: double double bag peritoneal dialysis solution, mask, iodophor cap , peritoneal dialysis clip, and check the volume, concentration and validity period of the peritoneal dialysis fluid, the validity period of the iodophor cap and whether the package is airtight; 2) Wear a mask and wash your hands, open the outer bag of peritoneal dialysis fluid, and check the connector pull-ring, pipeline, Whether the broken plug and the dialysate bag are intact, if you need to add drugs, add the drug to the peritoneal dialysis solution at the dosing hole of the peritoneal dialysis bag 1 according to the doctor's prescription; 3) Take out the peritoneal dialysis outer tube on the patient to ensure that the external The tube is in a closed state, pull the ring of the fresh peritoneal dialysis fluid interface, remove the iodophor cap on the outer tube, and quickly connect the peritoneal dialysis fluid pipeline common joint connection port with the end of the peritoneal dialysis outer tube. The mouth of the outer dialysis tube faces down, avoid pulling the tube, and screw the common joint port and the outer tube until they are completely tight; Break the plug, hang the dialysate bag 1, put the waste bag 2 in a low position, turn on the outer tube rotary switch to start drainage, and observe whether the drainage fluid is turbid and whether there is protein clot, and close the outer tube after drainage; 5) Remove the peritoneal dialysis clip of the liquid inlet pipe 3, so that the dialysate flows into the waste bag 2, and then use the peritoneal dialysis clip to clamp the liquid outlet pipe 4; The peritoneal dialysis solution was quickly poured into the peritoneal cavity. After the perfusion was completed, the peritoneal dialysis outer tube was closed, and another peritoneal dialysis clip was used to clamp the inlet pipeline 3; 7) Tear off the outer packaging of the iodophor cap, and place the peritoneal dialysis outer tube downward. Separate the outer tube from the connection port of the peritoneal dialysis fluid pipeline, twist the iodophor cap and the outer tube until they are completely sealed, and discard the used items.

In the process of peritoneal dialysis fluid drainage and infusion, both medical staff and patients are often most worried that the peritoneal dialysis tube is not smooth, resulting in a significant slowdown in the rate of peritoneal dialysis fluid drainage from the abdominal cavity or infusion into the abdominal cavity, or even unable to Drain or infuse. There are many clinical reasons for the obstruction of the peritoneal dialysis tube, such as: 1. A large number of protein clots in the abdominal cavity block the peritoneal dialysis tube due to infection and other reasons; 2. The omentum or other organs wrap the peritoneal dialysis tube; 3. The peritoneal dialysis tube Tube shift, etc. Among them, protein clots are the most common blockage of the peritoneal dialysis tube. In clinical practice, doctors often need to immediately disconnect the connection port between the peritoneal dialysis outer tube and the peritoneal dialysis fluid pipeline, and then use a syringe containing heparin saline to connect the peritoneal dialysis outer tube for heparin saline. through the tube. After catheterization, patients often need to reconnect peritoneal dialysis fluid for dialysis treatment. According to the principle of sterility, and in order to avoid abdominal infection caused by improper operation of patients, once the connection port of the peritoneal dialysis fluid is disconnected from the outer peritoneal dialysis tube, it cannot be reconnected for the second time, and a new peritoneal dialysis fluid needs to be replaced for treatment. , which resulted in the waste of the original peritoneal dialysis solution, further increasing the economic burden of patients.

SUMMARY OF THE INVENTION

In order to solve the technical problem that the existing peritoneal dialysis fluid system cannot be reused when the peritoneal dialysis tube is blocked during the process of peritoneal dialysis fluid drainage and infusion, the utility model provides a double-connected double-bag multi-joint peritoneal dialysis fluid The system can avoid the waste of the peritoneal dialysate system caused by the blockage of the pipeline after the heparin saline catheter treatment.

The technical scheme adopted by the utility model to solve its technical problems is:

In order to control the peritoneal dialysis fluid, a breaking plug is further provided in the connection between the fluid inlet pipeline 3 and the peritoneal dialysis fluid bag 1 . The broken plug is equivalent to a switch, which can block the outflow of the peritoneal dialysis fluid. When it is needed, it can be broken off, and the peritoneal dialysis fluid can flow out smoothly.

It is customary to use two common joints, namely the first joint and the second joint. When the first joint fails, the second joint is enabled. According to actual experience, generally do not try the third time.
