[Problems to be Solved by Prior Art and Invention]

 FIG. 4 is a schematic view of a currently used catheter fixing tool 31. The catheter fixing tool 31 is composed of a disc-shaped main body 32 and a catheter insertion port 33 projecting from the main body 32. However, since the catheter insertion port 33 is vertically projecting from the main body 32, the catheter tube 34 is bent at the rising of the catheter tube 34 and is apt to be blocked. In addition, since it is necessary to fix the end portion of the main body 32 with a suture thread, it is troublesome. Therefore, the present inventor arrived at the next inventor as a result of earnest studies to solve the above problems.

【Example】

 FIG. 1 is a schematic view of a catheter fixing tool 1 of the present invention (hereinafter, “fixing tool 1”). The fixture 1 is configured by connecting the main body 2 and the lid 3 via a hinge 4. A wide ridge 6 and a narrow ridge 7 are formed on the surface of the body 2, and a catheter fixing groove 5 is formed in the length direction of the body 2 from the ridge 6 to the ridge 7. A needle hole 12 is formed on a side portion of the narrow ridge portion 7, and a tip of a subcutaneous indwelling needle 10 formed into a curved shape in the needle hole 12 is inserted. The needle hole 12 is formed so as to penetrate the body 2 along the shape of the curved subcutaneous indwelling needle 10. The rear end of the subcutaneous indwelling needle 10 (two in FIG. 1, but at least one or more) is fixed to the needle base 11. A hook-shaped first needle retainer 13 is formed on a side portion of the needle hole 12. A fitting groove 8 corresponding to a catheter retainer 15 described later is formed in the catheter fixing groove 5 on the side of the raised portion 6, and a locking groove 9 corresponding to a lid retainer 14 described later is formed on a side portion of the main body 2. ing.

The lid 3 is composed of a catheter retaining lid 3A and a needle retaining lid 3B. The catheter retaining lid 3A has a catheter retaining portion 15 corresponding to the fitting groove 8 formed at an end thereof, and the locking groove on a side portion thereof. The lid clamp 14 corresponding to 9 is formed. The other-direction retention lid 3B has a second needle retainer 16 having fitting grooves 17 and 18 corresponding to the needle retainer 11 and the needle retainer 13 on the side, and a retainer retainer 14 corresponding to the locking groove 9. And a catheter groove 19 is formed at the end. Further, by constructing the entire fixture 1 with an antibacterial resin, the antibacterial property with the catheter insertion part can be maintained. Any known antibacterial resin can be used.

Next, a method of using the fixture 1 will be described. A catheter (not shown) is attached along the catheter fixing groove 5, and the catheter retaining lid 3A is fitted to the main body 2. The catheter is pressed by the catheter retainer 15 and strongly fixed to the main body 2, and the lid retainer 14 locks the catheter retainer lid 3A with the main body 2. Subsequently, as shown in FIG. 2, the subcutaneous indwelling needle 10 is half-turned along the raised portion 7 to fix the needle base 11 with the needle anchor 13 to fix the subcutaneous part of the human body and the body 2. Subcutaneous indwelling needle 10 can be indwelled subcutaneously in the same trajectory through needle hole 12. Further, the tip of the needle 10 can be rotated and stored in the needle hole 12 of the main body 2. Finally, the needle retention lid 3B is fitted to the main body 2 and the needle 10 is double-locked by the needle retention 16. At the same time, the lid 14 locks the needle retention lid 3B with the main body 2.

[Function and effect of the device]

 (1) Since the catheter is fixed parallel to the skin, there is less obstruction due to bending of the catheter. (2) The procedure can be simplified because the needle can be easily fixed subcutaneously by rotating it half way.
