Detailed Description

The present invention will be described in detail with reference to the following embodiments, wherein like or similar elements are designated by like reference numerals throughout the drawings or description, and wherein the shape, thickness or height of the various elements may be expanded or reduced in practical applications. The embodiments of the present invention are provided only for illustration, and not for limiting the scope of the present invention. Any obvious and obvious modifications or alterations to the present invention can be made without departing from the spirit and scope of the present invention.

Example 1

Referring to fig. 1, in an embodiment of the present invention, an external fixing device for a peritoneal dialysis catheter includes a bottom plate 1; the top of the bottom plate 1 is fixedly connected with a buckle 2, and the fixing mode can adopt glue adhesion and the like; the structure of the buckle 2 is tubular, and a bayonet is arranged on one side of the buckle 2; preferably, the bottom plate 1 and the buckle 2 both adopt silica gel, so that skin and a conduit are prevented from being scratched; the bottom plate 1 and the buckle 2 are integrally processed, so that the connection is tighter; the edge of the buckle 2 is rounded, so that the catheter is more convenient to mount; during production, the inner diameter of the buckle 2 is slightly smaller than the outer diameter of the peritoneal dialysis catheter, for example, the outer diameter of the peritoneal dialysis catheter is 5mm, and the inner diameter of the buckle 2 is 4.5 mm; therefore, the peritoneal dialysis catheter is plugged into the buckle 2 from the bayonet, and then the peritoneal dialysis catheter and the buckle can be fixed; the bottom of the bottom plate 1 is fixedly covered with a back adhesive layer 3, the back adhesive layer 3 is made of waterproof and oilproof adhesive fabric with good biocompatibility, and the possibility of adhesive fabric allergy and skin inflammation injury of patients with sensitive skin is avoided; the device can be fixed on the skin through the back adhesive layer 3, so that the peritoneal dialysis catheter is fixed, and the condition that the adhesive plaster is easy to fall off due to weak strength in the traditional fixing mode is avoided; the adhesive component of the adhesive plaster can not remain on the catheter, and the catheter can not be damaged.

Example 2

Referring to fig. 2-3, on the basis of embodiment 1, two buckles 2 are arranged at the top of the bottom plate 1, and the two buckles 2 are respectively located at two ends of the bottom plate 1, so that the bottom area of the bottom plate 1 is larger, and the adhesion between the bottom plate 1 and the skin through the back adhesive layer 3 is more stable; the bayonet directions of the two buckles 2 are opposite, so that the clamping of the catheter peritoneal dialysis catheter is more stable and is not easy to fall off, the peritoneal dialysis catheter is effectively fixed on a straight line, the movement in all directions can be avoided, and the traction damage of the catheter movement to an outer opening is avoided;
