- a rotating table is provided with a plurality of the above heating jigs, and each heating jig is a thermoplastic tube (soft polysalt-bulb resin tube) that is a member constituting an AVF needle.
- a needle base (hub) 7 composed of the following was inserted and fitted into a bonded state, and set in a state of being clamped in each of six molds 13 arranged on a synthetic resin molten mold base 14.
- Each of the six molds 13 'placed on the molten mold table 14' was set in a clamped state.
- one of the plurality of heating jigs holding the AVF needle component member in a joined state was first moved by rotating the rotating member to the heating jig heating section.
- This heating jig heating section has coils 15 and 15 ', and by causing a high frequency current to flow through the coils, Joule heat is generated in the heat conductive plates 12 and 2', and this heat is generated as described above. Heat is transferred to the synthetic resin molten molds 13 and 13 ′, the synthetic resin molten molds 13 and 13 ′ are heated, and the components of the AVF needle sandwiched between the molds 13 and 13 ′ are heated. Fused.
- the part surface portion of the synthetic resin melting mold is not heated, and the fusion is insufficient in the circumferential direction of the heat-sealing portion.
- the synthetic resin melting mold is closed again. After that, it is preferable to perform reheat fusion.
- the heating jig in which the constituent members of the AVF needle are thermally fused in the heating jig heating unit is moved to the cooling means and cooled, and at the same time, the heating The jig heating unit is controlled by the control device so that heating is started at the same time that the heating jig holding the following AVF needle component member in the joined state is moved.
- the medical synthetic resin member when heat-sealed, for example, a relatively soft thermoplastic tube constituting the AVF needle and other parts harder than the tube, for example, a wing shape
