Embodiment Construction

[0037] like Figure 1 to Figure 7 In the shown embodiment, the synthetic resin material is extruded by an extruder 3, and at the same time, it is stretched with a certain force to reduce the diameter, that is, the synthetic resin pipe 1 is formed while the diameter is fixed. The diameter reduction of the pipe material 1 is called pull-down in this way. like figure 1 As shown, in the cooling water tank 4, the pipe material 1 through sizing is cooled, and its size is specified.

[0038] Heat the top of the pipe material 1 that makes like this with heating device 5, as figure 2 As shown, the heated portion expands while melting. The size of the expanded portion 1a formed at this time is approximately the size of the pipe material 1 before being drawn down. This is a general characteristic of synthetic resin catheters. The present invention focuses on the above-mentioned characteristics of synthetic resin catheters and applies them to bonding.

Abstract

The invention provides a guide pipe and a bonding device thereof. The device can simply weld pipes onto a target surface after the pipes are continuously manufactured and cut into the pipes with the required length. A synthetic resin material is extruded by an extruder, the diameter is reduced by pull-down, a pipe made of synthetic resin is formed, the top of the pipe is heated and expanded, a heating device is pressed onto the bonded surface of the pipe made of the synthetic resin to heat and melt the pipe, and a melting recess corresponding to a cylindrical bulge of the heating device is formed on a heating and melting part; meanwhile, melted resin of which the volume size is equivalent to that of the melting recess is extruded to the periphery of an opening of the melting recess, the melted resin formed at the periphery of the opening and the extruded melted resin form an integrated melting part, the end of the pipe is in compression joint with the heated melting recess and the heated melting part of the bonded surface through the heated expansion part, and the expansion part is bonded to the melting recess and the melting part.

Description

technical field [0001] The present invention relates to a catheter for bonding a thin synthetic resin catheter to a surface to be bonded, and a bonding device thereof. Background technique [0002] When bonding the tip of a thinner catheter to the target surface, because the bonding area of ​​the catheter tip is very small, it is usually extremely difficult, and in fact it has not been practically applied. However, it is theoretically conceivable that Figure 8 As shown, the flange portion 2 may be formed in advance on the tip of the pipe material 1, and the flange 2 may be fused to the target surface. [0003] However, in the case where the flange portion 2 is formed at the tip of the pipe material 1 as described above, the pipe material 1 cannot be continuously manufactured and the cutting length is determined according to the application. Therefore, only according to its specific purpose of use, the length of the catheter is predetermined, and the catheter is manufacture...
