[0035] Please refer to Figures 1-4 , the present utility model provides a technical solution: an infusion tube fixing device, comprising:

[0039] When in use, the infusion tube is placed inside the positioning member 100 through the mounting opening 101, and the elastic positioning member 100 can extrude the infusion tube to realize the wrapping of the infusion tube by the positioning member 100. Among them, the positioning member 100 cooperates with the supporting member 200 to support the infusion tube in the length direction of the positioning member 100, avoiding the problems of unsmooth or interrupted infusion caused by the bending of the infusion tube;

[0040] In addition, compared with the existing method of fixing the infusion tube to an external fixing surface with adhesive tape, where the infusion tube and the fixing surface are on the same side of the adhesive tape and there is an easy existence of a gap between the adhesive tape and the fixing surface, resulting in the detachment or position change of the infusion tube and affecting the fluid infusion rate. For this fixing device, the positioning member 100 is located on the opposite side of the adhesive surface 302. The positioning member 100 and the infusion tube inside the positioning member 100 can be precisely arranged on the external fixing surface in cooperation with the adhesive surface 302 on the fixing member 300, so as to maintain a constant fluid infusion rate for the patient, which is particularly important for patients in the intensive care unit with unstable circulation and requiring a constant infusion rate.

[0041] It should be noted that the external fixing surface can be the patient's skin or the surface of the hospital bed.

[0042] See Figures 1-3 , further, two adjacent positioning members 100 are respectively a first positioning member 100a and a second positioning member 100b. The fixing device further includes a connecting member 400. The connecting member 400 is connected to one end of the first positioning member 100a close to the second positioning member 100b. An engaging groove 500 is formed at one end of the second positioning member 100b facing the first positioning member 100a, and the engaging groove 500 matches the connecting member 400.

[0044] Specifically, the engaging groove 500 includes an inlet portion 501, a limiting portion 502, and a positioning portion 503 that are sequentially connected along the circumferential direction of the second positioning member 100b. The opening edge of the limiting portion 502 and the opening edge of the positioning portion 503 extend inward, and the opening edge of the limiting portion 502 and the opening edge of the positioning portion 503 enclose a constraining portion 504;

[0046] When it is necessary to adjust the length of the positioning member 100, the connecting member 400 on the first positioning member 100a is inserted into the connecting groove 500 on the second positioning member 100b, and the second connecting portion 402 is inserted into the entering portion 501. Rotate the first positioning member 100a or the second positioning member 100b along the circumferential direction of the positioning member 100. The second connecting portion 402 enters the positioning portion 503 through the limiting portion 502, and the constraining portion 504 cooperates with the positioning portion 503 to limit the second connecting portion 402, thereby realizing the fixation of the relative position between the first positioning member 100a and the second positioning member 100b. Through the above operations, the overall length of the positioning member 100 can be adjusted, so that the length of the positioning member 100 is sufficient to cover the key parts of the infusion tube and prevent the infusion tube from being folded. It should be noted that in one of the embodiments, the key part of the above infusion tube refers to the connection part between the infusion tube and the three-way joint.
