[0002] Peritoneal dialysis technology mainly implants a peritoneal dialysis catheter made of silica gel into the peritoneal cavity of a patient through a surgical method. However, the implanted peritoneal dialysis catheter often undergoes displacement, that is, the so-called "floating catheter", and dialysis treatment cannot be carried out. It is necessary to deal with it in time to avoid delaying the treatment of the patient.

[0003] At present, the methods for peritoneal dialysis catheter resetting usually include taking laxatives to increase intestinal peristalsis for resetting; strengthening exercises such as climbing stairs and standing on tiptoe for resetting, resetting by massaging the abdomen including pressing, kneading, squeezing and other techniques, fixing or re-implanting the peritoneal dialysis catheter by surgical methods. The above resetting methods have many disadvantages. Laxatives and excessive exercise damage the physical health of patients and increase the physical burden of patients. It is difficult to reset. Manual resetting and secondary surgery will cause too much psychological burden to patients, increase the economic burden of patients, the above resetting treatment has great technical difficulty, difficult to control the treatment effect, high degree of secondary injury to the body and mind of patients, increased probability of aggravating the condition, and laying hidden dangers for subsequent treatment.

[0018] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings:

[0019] As Figures 1 - 4As shown in the figure, the working principle of an artificial injector for assisting in the reset of an abdominal dialysis catheter is as follows: The luer connector 1 provided at the top of the injector body 3 is firmly connected to the connection port of the abdominal dialysis catheter remaining outside the patient. By means of pulsed rapid pressure perfusion of peritoneal dialysis fluid, the peritoneal dialysis fluid enters the abdominal dialysis catheter through the injection port 11 and finally reaches the patient's abdominal cavity. After repeated injections, the patient feels a sense of water flow impact in the lower abdomen, indicating that the abdominal dialysis catheter has returned to the correct position. A one-way piston 15 is provided at the position of the injection port 11 to prevent the peritoneal dialysis fluid from flowing back into the injector body 3 along the injection port 11. A one-way valve 12 is provided at the position of the liquid inlet 10 of the liquid inlet pipe 7 in the injector body 3 to prevent the peritoneal dialysis fluid from flowing back into the liquid inlet pipe 7 and the peritoneal dialysis fluid bag 17 through the liquid inlet 10.

[0020] As Figures 1 - 4 As shown in the figure, an artificial injector for assisting in the reset of an abdominal dialysis catheter includes an injector body 3. A luer connector 1 is provided at the top end of the injector body 3. The luer inner cavity 14 of the luer connector 1 is inserted into the connection port of the abdominal dialysis catheter remaining outside the patient. The luer inner helix 13 of the luer connector 1 is connected to the outer helix of the connection port. An outer helix is provided at the connection port and is connected and fixed in cooperation with the inner helix of the luer inner helix 13. After connection, the entire luer connector 1 fully wraps the connection port, achieving a sterile state, and this structure is tightly connected, capable of preventing the injector from detaching from the connection port when manually applying force; A one-way piston 15 is provided at the position of the injection port 11 in the injector body 3 and is fixed by a cross 16. The one-way piston 15 functions as a one-way valve. During the process of the injector injecting peritoneal dialysis fluid, the one-way piston 15 allows the injector body 3 to inject peritoneal dialysis fluid into the abdominal dialysis catheter and does not allow the peritoneal dialysis fluid in the abdominal dialysis catheter to flow back into the injector body 3; A plunger rod 9 is provided inside the injector body 3. A liquid inlet pipe 7 is provided on one side of the plunger rod 9. A one-way valve 12 is provided at the position of the liquid inlet 10 at one end of the liquid inlet pipe 7. The one-way valve 12 only allows the peritoneal dialysis fluid in the peritoneal dialysis fluid bag 17 to flow into the injector body 3 and does not allow the peritoneal dialysis fluid to flow back from the injector body 3 into the peritoneal dialysis fluid bag 17. A fixed handle 8 is provided on the plunger rod 9, and a push handle 4 is provided at the tail end of the plunger rod 9. The fixed handle 8 is fixedly connected to the liquid inlet pipe 7, ensuring that the part of the liquid inlet pipe 7 inside the injector body 3 is parallel to the plunger rod 9, reducing the folding and twisting of the liquid inlet pipe 7 and reducing the injection resistance. The push handle 4 facilitates manual pushing of the plunger rod 9 to quickly inject peritoneal dialysis fluid.

[0021] As Figure 1 As shown in the figure, further, the other end of the liquid inlet pipe 7 is connected to a plastic steel needle 5, and the plastic steel needle 5 is inserted into the peritoneal dialysis fluid bag 17.

[0022] As Figure 1As shown, further, a clamp 6 is provided on the tube body of the liquid inlet tube 7 near the plastic steel needle 5. When replacing the peritoneal dialysis solution bag 17, the clamp 6 is closed to ensure that no gas enters the liquid inlet tube. There is no need to disconnect the connection between the Luer connector 1 and the peritoneal dialysis tube. Just pull out the plastic steel needle 5, cover the needle cap, insert the plastic steel needle 5 after replacing the peritoneal dialysis solution bag 17, open the clamp 6, and continue the operation, saving treatment time.

[0023] As Figure 1 shown, further, a scale mark 2 is provided on the syringe body 3, and the scale mark 2 records the liquid volume used in the operation.

[0024] Further, the push handle 4 is made of silicone material, and the silicone material reduces the pain in the operator's palm caused by the reaction force generated during the operation.

[0025] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
