In the present application, the first wristband 1 is a hollow cylindrical structure, and the three-way joint hard accommodating cavity 2 is used to accommodate the three-way joint 15 of the retaining needle. The tightening area and the three-way joint hard accommodating cavity 2 can be two surfaces respectively arranged on the inside of the first wristband 1 that are opposite to each other. The three-way joint hard accommodating cavity 2 is a hard structure, which can better fix and protect the three-way joint. When the three-way joint 15 of the retaining needle is placed in the three-way joint hard accommodating cavity 2 After being inserted, the first wristband 1 is tightened by shrinking the first wristband 1 in the circumferential direction through the tightening area to better match the shape of the patient's arm and fix the three-way joint more securely. When in use, after the medical staff fixes the indwelling needle needle 14 through the film, the three-way joint 15 of the indwelling needle needs to be fixed. At this time, the first wristband 1 is put from the patient's hand to the patient's wrist, the position of the first wristband 1 is adjusted, the indwelling needle three-way joint is placed in the three-way joint hard accommodating cavity 2, and then the first wristband 1 is tightened by the tightening piece 3. At this time, the indwelling needle three-way joint is further fixed to it after the first wristband 1 is tightened, and the shape of the three-way joint hard accommodating cavity 2 is adapted to the three-way joint. The three-way joint is placed inside the first wristband 1 for fixation. Firstly, it avoids the problem of the tape falling off due to sweating of the patient's skin or friction and warping of the tape surface after being fixed with medical tape, thereby achieving a more stable fixing effect on the three-way joint. Secondly, it also avoids the problem of dust falling into the infusion port due to the three-way joint being exposed to the outside. Thirdly, it avoids the problem that the three-way joint is a three-dimensional structure and is easily knocked and fallen off if it is directly pasted on the patient's skin surface and is usually located on the outside of the arm. The solution of the present application solves the above problems, wherein the tightening area is the area on the inner surface of the first wristband 1 where the tightening member 3 is fixedly arranged.
