Referring to fig. 1-4, the present invention provides a technical solution:

the invention provides a central venous catheter fixer, which is provided with a fixing paste 2 and a fixing buckle 3 for fixing a venous catheter quickly and painlessly. The pipe joint comprises a main pipe 1 and a pair of branch pipes 10, wherein one ends of the branch pipes are connected in an inserted mode, and a butterfly-shaped fixing sticker 2 is arranged below the main pipe 1, so that the whole pipe joint is attractive, the contact surface is large, and the pipe joint is firm. The top surface of the fixing paste 2 is provided with a fixing buckle 3 connected with the branch conduit 10. The center of the top surface of the fixed sticker 2 is provided with a strip-shaped viscous groove 20, and a glue layer 21 is bonded inside the viscous groove 20, so that the glue layer 21 is not raised. The upper half part of the glue layer 21 is bonded with the main duct 1, so that the main duct 1 is fixed on the fixing sticker 2. The fixing buckle 3 is of a bilateral symmetry structure, a square fixing plate 30 is arranged between the adjacent ends, and the fixing plate 30 is bonded with the lower half part of the glue layer 21, so that the fixing buckle 3 is fixed on the fixing sticker 2. Two rows of convex columns 31 are symmetrically arranged on the top surface of the fixing plate 30 and on the same side of the fixing buckle 3, a blank holder 33 is vertically arranged at one end of the fixing buckle 3 far away from the fixing plate 30 downwards, the fixing buckle 3 is rolled upwards, and the blank holder 33 is attached to the top surface of the fixing plate 30. The side surfaces of the pressing edges 33 are symmetrically provided with sleeve holes 34 which are matched with the same-side convex columns 31 in an inserting manner, so that the pressing plates 33 are stabilized on the fixing plate 30, the fixing buckles 3 are shaped into a circular ring structure, and the sleeve column distribution guide pipes 10 are facilitated.

In this embodiment, the fixing patch 2 is made of an anti-allergic skin-friendly material, and the fixing buckle 3 is made of a PP material and is of an integrally formed structure, so that the fixing patch is light in weight, good in toughness, rigid in strength and not easy to break.

Further, the branch ducts 10 are covered by the fixing buckles 3 which are rolled up in a circular ring, thereby preventing the branch ducts 10 from slipping off the main duct 1.

Specifically, the bottom surface of the fixing sticker 2 is also coated with a layer of glue, and a protective film 22 is adhered to the bottom surface of the glue, namely a PE film, and the fixing sticker 2 can be adhered to the skin to be fixed by tearing off the protective film 22.

In addition, the outer diameter of the upper half section of the convex column 31 is larger than that of the lower half section of the convex column 31, the outer diameter of the sleeve hole 34 is matched with that of the lower half section of the convex column 31, and the fixing buckle 3-position plastic product can be deformed under stress, so that the sleeve hole 34 is expanded when being sleeved into the top end of the convex column 31 and is sleeved into the lower half section of the convex column 31 without slipping, and the fixing buckle 3 is ensured to keep a circular ring structure to clamp the branch conduit 10.

It should be supplemented that the joint of the fixing buckle 3 and the fixing plate 30 is provided with a folding groove 32 in a triangular prism structure, the folding groove 32 does not penetrate through the fixing buckle 3, the fixing buckle 3 is favorably folded upwards, and the folding groove 32 avoids interference.
