Embodiment 1

[0029] like Figure 4 As shown, as another specific embodiment of strengthening the anti-stretch, the flexible adapter plate 6 is provided with a second anti-stretch pad 12 for welding with the anti-stretch wire 7-2 in the transmission cable 7 .

[0030] During specific welding, it is sufficient that the slack of all the wires 7-1 be greater than that of the anti-stretch wire 7-2. The plate is first stressed, so as to avoid pulling the solder joint at the end of the wire 7-1, thereby protecting the solder joint of the wire.

[0031] like figure 2 As shown, the circuit contacts on the front and back of the wiring board 5 are welded with the transfer contacts 8-1 on the edges of the two ends of the flexible adapter plate 6 to form a plurality of solder joints 9, and the solder joints are connected to corresponding circuits, and the solder joints make The fixed wiring board 5 and the flexible adapter board 6 are fixedly connected. The transition contacts 8-1 at the edges of ...

Abstract

The invention relates to a flexible circuit board patch cord structure and an electrode patch for treating tumors in an electric field. The patch cord structure comprises a flexible circuit board, a wiring board is arranged on the flexible circuit board, and line contacts at the end heads of a plurality of circuit wires are gathered on the front and back surfaces of the wiring board; the adapter plate is a rectangular strip-shaped flexible adapter plate, two ends of the adapter plate are respectively provided with a plurality of adapter wires, and two ends of each adapter wire are respectively provided with an adapter contact piece; after the flexible adapter plate is folded, the rotary contact pieces at the edges of the two end parts are respectively welded with the line contact pieces on the front and back surfaces of the wiring board, and the rotary contact piece close to the middle part is welded with a plurality of leads in the transmission cable. The electrode patch comprises the flexible circuit board patch cord structure.

Description

technical field [0001] The invention relates to a flexible circuit board transfer wire structure and an electrode patch for treating tumors with an electric field. Background technique [0002] Due to the continuing limitations of currently available cancer therapies including chemotherapy or radiotherapy, new treatment modalities including electrical stimulation have recently attracted extensive research exploration or clinical application interest. Medium-frequency electric fields have long been considered to have no significant effect on biological processes because their alternation is too fast to cause effective neuromuscular stimulation, and low intensities can only cause limited heating effects. However, in recent years, research and clinical studies have found that when the frequency of the electric field is in the range of 100-500 kHz, the external alternating electric field can significantly inhibit the growth rate of different cancer cells in vitro and in vivo. S...
