  Between the first fixing portion 22 and the second fixing portion 24 in the fixture main body 12, a catheter support portion 30 that supports the fixation target portion 104 of the catheter 102 is provided. A reinforcing member 32 is provided on the outer surface of the catheter support portion 30. The reinforcing member 32 extends in a quadrangular shape along the outer circumference of the catheter support portion 30 and extends along the slit 16 and the catheter insertion hole 18. The reinforcing member 32 is made of a material having transparency (light transmittance) and moisture permeability. As a constituent material of the reinforcing member 32, for example, the same constituent material as that of the fixture main body 12 can be used.

  The reinforcing member 32 may be provided not on the outer surface of the catheter support part 30 but on the back surface (the surface on the side in contact with the patient's skin 100a). Further, the reinforcing member 32 may be provided on both surfaces of the catheter support portion 30. In this case, the strength of the catheter support part 30 can be further improved.

  In FIG. 1C, the back surface of the catheter support part 30 is provided with a plurality of back-side adhesive parts 34 that can adhere (adhere) the catheter fixture 10 to the patient's skin 100a. The back side adhesive part 34 is formed in a circular shape. The adhesive strength of the back side adhesive part 34 is set to such an extent that it can be peeled off from the skin 100a. The plurality of back side adhesive portions 34 can be arbitrarily arranged on the back surface of the catheter support portion 30.

  The catheter fixture 10 according to the present embodiment is basically configured as described above. Next, a method of using the catheter fixture 10 will be described. In the following description, as shown in FIGS. 2 and 3, the fixing target portion 104 of the catheter 102 (the proximal end side of the catheter tube 106, the catheter hub 108, and the extension tube) placed in the blood vessel of the patient's arm 100. The case where a part of 110 is fixed to the skin 100a of the arm 100 by the catheter fixture 10 will be described.

  First, the user passes the proximal end side of the catheter tube 106 (exposed portion outside the body) through the slit 16 and inserts it into the catheter insertion hole 18. Then, as shown in FIG. 2, the back side adhesive portion 34 of the fixture main body 12 is adhered to the skin 100 a of the arm 100. Thereby, the fixture main body 12 is fixed to the skin 100a of the arm 100. Further, the fixation target portion 104 of the catheter 102 is positioned on the outer surface of the catheter support portion 30 of the fixture main body 12. At this time, in the example of FIG. 2, the extension tube 110 connected to the proximal end of the catheter hub 108 is bent 180 degrees toward the catheter tube 106 side.

  After that, as shown in FIG. 3, the fixture body 12 is wound around the arm 100 so that the fixation target portion 104 of the catheter 102 is covered by the fixture body 12, and one end portion of the fixture body 12 is connected to the first fixing portion 22. And one end side of the fixture main body 12 (the other end side of the one end portion of the fixture main body 12) is adhered to the second fixing portion 24. At this time, the user grasps one end side of the fixture main body 12 and winds the fixture main body 12 around the arm 100 while pulling the fixture main body 12 outward in the extending direction, thereby fixing the fixture main body 12 to the arm 100 without loosening. can do.
