Problems solved by technology

[0003] In daily care, it is necessary to keep the outlet of the insertion tube dry. If you do not pay attention, catheter-related infection, especially tunnel infection, may occur. In order to prevent tunnel infection, you need to push the insertion tube slightly Pull out for a certain distance, and then smear alcohol or iodophor on the surface of the insertion tube for disinfection. However, since the material of the insertion tube is generally made of silica gel, alcohol and iodophor are often used for disinfection, which will cause the insertion tube to become hard and brittle. Intra-abdominal rupture is prone to occur, and the frequent insertion and extraction of the insertion tube not only increases the pain of the patient, but more importantly, it also increases the risk of bacterial infection

Embodiment 1

[0034] An anti-tunnel infection type peritoneal dialysis insertion tube, such as figure 2 , 4 , 5 and 6, including the inner tube body 1 indwelling in the abdominal cavity and the joint tube 4 outside the patient's body for connecting with the peritoneal dialysis equipment, the joint tube 4 is outside the patient's body, closed at ordinary times, and opened when performing dialysis. The peritoneal dialysis equipment is connected; the bottom end of the joint tube 4 is provided with a flexible silica gel disc 3 attached to the abdominal skin surface, and the flexible silica gel disc 3 is a disc 301 made of silica gel material, which can be attached to the patient's abdominal skin, thereby Auxiliary insertion tube is fixed. The flexible silica gel disc 3 is actually a disc with a through hole in the middle. The inner tube body 1 is connected to the flexible silica gel disc 3 through a section of drug penetration tube 2. The dialysate injected from the joint tube 4 passes through...

Embodiment 2

[0037] This embodiment is an improvement made on the basis of embodiment 1, its main structure is the same as that of embodiment 1, and the improvements are as follows: Figure 5 and 6 As shown, the upper surface of the flexible silica gel disc 3 is also provided with a liquid sampling tube 304, the liquid sampling tube 304 and the liquid medicine filling port 302 are located at different positions on the flexible silica gel disc 3, and are staggered from each other without mutual influence. The tube 304 communicates with the top of the liquid storage chamber 202 through another channel in the flexible silicone disc 3, and the liquid in the liquid storage chamber 202 is extracted through an external sampling tool for testing, so as to check whether infection occurs. The external sampling tool generally uses a syringe. The liquid sampling tube 304 is a tubular part protruding from the surface of the flexible silicone disc 3, which is closed with a plug at ordinary times. When i...

Embodiment 3

[0039] This embodiment is another improvement made on the basis of embodiment 1, its main structure is the same as that of embodiment 1, and the improvements are as follows: Figure 7 and 8 As shown, the drug penetration tube 2 is arranged around the outer wall of an expandable sleeve 5, and the inside of the expandable sleeve 5 forms a dialysate channel connecting the joint pipe 4 and the inner tube body 1, and the expandable sleeve 5 is preferably a solution It is a cylindrical shape made of medical silicone material, and its side wall is hollow, and the expansion or contraction of the expandable sleeve 5 can be realized by injecting or pumping liquid or gas into it, and the expansion and contraction of the expandable sleeve 5, The expansion and contraction of the dialysate channel will not affect the smooth flow of the dialysate channel. The top of the expandable sleeve 5 is connected to the lower surface of the flexible silicone disc 3, and is arranged on the inlet of the ...

Abstract

The invention provides a tunnel infection prevention type peritoneal dialysis imbedding tube. The tunnel infection prevention type peritoneal dialysis imbedding tube comprises an inner tube body remaining in an abdominal cavity and a connector tube located outside a patient and used for being connected with peritoneal dialysis equipment, a flexible silica gel disc is arranged at the bottom end of the connector tube, the inner tube body is connected with the connector tube through a section of medicine seepage tube, the medicine seepage tube comprises a sleeve, and a cavity is formed in the side wall of the sleeve. Polyvinyl alcohol fibers are filled in the cavity to form a liquid storage cavity, a liquid medicine filling opening is formed in the upper surface of the flexible silica gel disc, the surface of the medicine seepage tube is divided into a medicine seepage area and a non-medicine-seepage area, the medicine seepage area is located in rectus abdominis and tissue, and the non-medicine-seepage area is closer to the skin surface relative to the medicine seepage area. By means of the built-in medicine seepage tube and the flexible silica gel disc located on the body surface of the abdomen, disinfection of the interior of the imbedding pipe body can be completed without inserting and pulling out the imbedding pipe, the pain of a patient is relieved, meanwhile, the bacterial infection risk caused after pulling out is avoided, and the incidence rate of tunnel infection is effectively reduced.

Description

technical field [0001] The invention relates to a peritoneal dialysis device in the nephrology department, in particular to a tunnel infection-preventing peritoneal dialysis insertion tube. Background technique [0002] In the existing peritoneal dialysis insertion tube, the part in the abdominal cavity is fixed with the rectus abdominis and other tissues, and the other end extends out of the body to form a joint tube. When peritoneal dialysis treatment is required, the joint tube is directly connected to the peritoneal dialysis equipment. When no treatment is needed, the joint tube is fixed with an abdominal belt to prevent accidental contact with the joint tube and the displacement of the part of the implanted tube in the abdominal cavity; [0003] In daily care, it is necessary to keep the outlet of the insertion tube dry. If you do not pay attention, catheter-related infection, especially tunnel infection, may occur. In order to prevent tunnel infection, you need to push...
