The indwelling catheter 2 can be manually controlled to move back and forth along the length direction of the drainage catheter 1. The expansion fixing structure 4 is provided at one end in the same direction as the drainage catheter 1. When the indwelling catheter 2 moves toward the end of the drainage catheter 1, the expansion fixing structure 4 is squeezed and deformed by force, and is fixed in an open state toward all sides.
[0024] like Figure 3As shown, during use, the utility model has a puncture device 3 disposed inside the drainage catheter 1, and the drainage catheter 1 is sleeved on the outer surface of the puncture device 3, and a hole is formed by penetrating the human body surface through the puncture device 3, and the drainage catheter 1 and the indwelling catheter 2 are synchronously inserted into the formed hole, and the expansion and fixing assembly and the front end of the drainage catheter 1 are both inserted into the hole, and after the inner edge of the hole is fitted and fixed with the outer surface of the indwelling catheter 2, the drainage catheter 1 is pulled outward to control the expansion and fixing structure 4 to open and fit with the inner surface of the body cavity, so as to prevent the indwelling catheter 2 from falling off from the puncture hole under force, thereby achieving a better fixing effect, facilitating subsequent care through the drainage catheter 1, and the wound is not easily touched during cleaning and dressing change, thereby reducing the patient's pain.
[0025] like Figure 2 and Figure 4 As shown, further, in the above scheme, a plurality of expansion groups 401 are arranged at equal intervals around the outer surface of the drainage catheter 1, and the expansion group 401 is composed of two expansion sheets 5 and three connecting parts 6. After the expansion fixing structure 4 is inserted into the hole, the expansion group 401 is expanded and fits on the inner wall of the body cavity under the pulling of the drainage catheter 1.

[0033] Furthermore, in the above solution, the outer surface of the indwelling catheter 2 is provided with an annular groove 201 recessed toward the indwelling catheter 2 , and both sides of the notch of the annular groove 201 are connected to the outer surface of the indwelling catheter 2 in an arc surface.
[0034] Furthermore, in the above solution, the drainage catheter 1, the indwelling catheter 2, the expansion sheet 5 and the connecting part 6 are made of one of polyvinyl chloride, polypropylene, polycarbonate and polymethyl methacrylate.
[0035] It should be noted that if Figure 6 As shown, after the expansion fixing structure 4 is opened and fixed, the end of the drainage catheter 1 will protrude outward along the human body's epidermis, and the longer end of the drainage catheter 1 extending along the human body's epidermis can be shortened by using a tool scissors, so that the extended length of the drainage catheter 1 is suitable for bonding and fixing to the human body surface by medical tape.
[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
