Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a tunnel flushing and disinfection catheter for dialysis and its use method with simple structure, easy operation and remarkable effect. There are two different methods of washing and smearing on the inflammation site, which effectively solves the problem of limited cleaning and disinfection of the tunnel and the inability of antibacterial drugs to reach the inflammation site of the tunnel

Embodiment 1

[0031] like figure 1 Shown: a tunnel flushing and disinfection catheter for dialysis, the catheter 1 is provided with an inclined port at the end inserted into the tunnel port (hereinafter referred to as the front end head 11) to form a main tip hole 2; and the section of the pipe extending into the tunnel is provided with A plurality of side holes 3; the end of the conduit 1 away from the tunnel mouth (hereinafter referred to as the rear end) is provided with a joint 4 for connecting a syringe.

[0032] Specifically, the front end 11 of the catheter 1 has a certain hardness, and the rest of the catheter except the front end is the hose 12, and the hardness of the front end is greater than the hardness of the hose 12, for example, a plastic head is used to facilitate smooth entry into the depths of the tunnel If the front end 11 is too hard, it is easy to damage or cut the soft tissue of the tunnel and the peritoneal dialysis catheter running in the tunnel; if the front end 11...

Embodiment 2

[0037] like figure 2 Shown: a dialysis tunnel rinsing and disinfecting catheter, the catheter 1' is provided with an inclined port at the end inserted into the tunnel port to form a main hole at the tip, and the back of the main hole at the tip and the section of the tube extending into the tunnel are provided with There is a rough surface 5 for adhering and applying the drug.

[0038] Specifically, the front end of the catheter 1' is designed to be provided with a main tip hole on one side and a rough surface on the other side. The catheter is preferably a plastic hose with a certain hardness, which can detect the depth of the tunnel inflammation and effectively reach the tunnel inflammation site with the external medicine.

[0039] In this embodiment, the rough surface 5 can be a polyester rough surface, or can be designed in a convex or groove structure, and the shape of the rough surface can be a grid shape, a spherical shape, a honeycomb shape, or the like. Preferably,...

Embodiment 3

[0043] The difference from Embodiment 2 is that the front end 11 of the catheter is a closed structure without a main hole at the tip, so that the catheter is only used for external drug smearing through the rough surface, and is not used for injecting liquid drugs.

[0044] Others are the same as in Example 2.

Abstract

The invention discloses a tunnel flushing and disinfecting catheter for dialysis and a using method thereof. An inclined opening is formed in the end, inserted into a tunnel opening, of the catheter, and a tip main hole is formed; a plurality of side holes are formed in one section of pipe body, extending into a tunnel target position, of the guide pipe; the hardness of the end head is greater than that of the pipe body; a connector used for being connected with an aspirator is arranged on the catheter. The invention further comprises another tunnel flushing and disinfecting catheter for dialysis and a using method of the tunnel flushing and disinfecting catheter. On one hand, the catheter can stretch into the deep position of a tunnel, the inflammation position of the tunnel can be effectively detected, flushing, disinfection and antibiosis are conducted in time, and deep tunnel inflammation or granulation is effectively treated in time; on the other hand, treatment in two different modes of flushing and smearing can be achieved; and moreover, the injection speed is moderate, and the problem that the infected kitchen falls off and is attached to other parts of the tunnel due to rapid flushing is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tunnel flushing and disinfection catheter for dialysis and a method for using the same. Background technique [0002] The global prevalence of chronic kidney disease (CKD) is 11-13%, and most patients enter end-stage renal disease (ESRD). Peritoneal dialysis is an important treatment method for ESRD. Compared with hemodialysis, peritoneal dialysis has the advantages of less hemodynamic impact and home operation, low medical cost and flexible treatment time. With the strong support of the government, it has developed rapidly. With the increase of peritoneal dialysis patients and the improvement of the management level of peritoneal dialysis centers, the patient's life expectancy with tube, dialysis age and quality of life have been improved. However, with the prolongation of the tube-carrying time, in addition to acute complications such as peritonitis, more and more c...
