Dialysis Catheter) is a dialysis catheter placed in the patient's body, and the catheter has a connector-exposed end that is attached to the medical device for peritoneal dialysis. However, the connecting end of the catheter is easily damaged after a long period of use and cannot be used to connect to medical equipment. At this time, one of the solutions is to cut off the damaged portion of the connecting end of the catheter, and then combine the other catheter at the connecting end of the original medical catheter to compensate for the damaged portion of the original connecting end. However, 'the inner diameter of the other catheter is usually smaller than the inner diameter of the connecting end of the original catheter, so that the other catheter can be inserted into the connection end of the original catheter to be combined into a body, resulting in the connection of the medical catheter after the combination. In the case where the inner diameter is inconsistent at the end, when the fluid flows through the connection end of the medical catheter, the fluid tends to generate turbulence at the inner diameter of the inner tube, resulting in easy growth of bacteria at the connection end of the medical catheter.

Wherein when the second conduit 200 abuts against the first conduit 100, the first guide 200 can be pressed toward the first conduit 100 to avoid a gap at the junction of the first conduit 1 and the second conduit. Then, the thermoplastic connecting film 300 is coated on the periphery of the abutting portion of the first conduit i (10) and the second guide f, and the thermoplastic connecting film 3 is heated to heat the thermoplastic connecting film 3 to be thermoformed. Thereby, the first catheter 100 and the second catheter 200 are combined to form an integral body (step 104). The heating method of the thermoplastic connecting film is, for example, using a coil to pass electricity/"L heating, or heating with a heat conductive metal member. Since the thermoplastic connecting film 300 can be rapidly thermoformed after heating, the first conduit and the first The two guides g 200 can quickly form a combination. Therefore, the combined method of the present embodiment can quickly combine the first duct 100 and the second duct 200, wherein the first duct 00 / the second duct 200 has the same inner diameter. To avoid the poor sanitary quality of the catheter caused by the inconsistent diameter of the catheter.
