Description

TECHNICAL FIELD

[0001] The application relates to an electrode patch and a tumor electric field treatment system, and belongs to the technical field of medical devices. BACKGROUND

[0002] At present, the treatment methods for tumors mainly include surgery, radiotherapy, chemotherapy and the like, but all have corresponding shortcomings, such as side effects of radiotherapy and chemotherapy, and killing of normal cells. The use of electric fields to treat tumors is also one of the current research frontiers. Tumor electric field treatment is a tumor treatment method that generates an electric field through a special electric field generator to interfere with the mitotic process of tumor cells through a low-intensity, medium-high frequency, alternating electric field. Studies have shown that electric field treatment has a significant effect in the treatment of diseases such as glioblastoma, non-small cell lung cancer and malignant pleural mesothelioma. The electric field applied by the treatment method can affect the aggregation of tubulin protein, prevent spindle formation, inhibit the mitotic process and induce apoptosis of cancer cells.

[0003] A tumor electric field treatment system for treating tumors mainly comprises an electric field generator and an electrode patch electrically connected to the electric field generator, wherein the electrode patch is attached to the skin of the human body in pairs to apply an alternating electric field to the human body lesion for alternating electric field treatment. Each electrode patch comprises a flexible circuit board, a plurality of ceramic pieces arranged at intervals on the flexible circuit board, and a wire electrically connected to the flexible circuit board, as disclosed in Chinese Patent Publication Nos. 11271272 or 113164745. The flexible circuit board comprises a flexible board base, a plurality of conductive traces embedded in the flexible board base, and a plurality of conductive pads exposed on the flexible board base and electrically connected to the same conductive trace. The plurality of ceramic pieces are arranged on the flexible circuit board by welding with the corresponding conductive pads, and are then connected in series through a conductive trace electrically connected to all the conductive pads. One end of the wire is electrically connected to the flexible circuit board, and the other end is provided with a plug that can be plugged into the electric field generator.

[0004] Since the ceramic pieces are hard materials and the flexible circuit board is a flexible material, the mechanical strength of the flexible circuit board of the electrode patch of the above-mentioned tumor electric field treatment system at the part where the plurality of ceramic pieces are arranged at intervals is stronger than that at the part where no ceramic pieces are arranged, and thus there is a risk of bending at the junction between the part where the ceramic pieces are arranged and the part where no ceramic pieces are arranged. If the bending is severe, there is also a risk of fracture of the conductive trace in the flexible board base. The plurality of ceramic pieces of the electrode patch are connected in series through the same conductive trace of the flexible circuit board, and there is a problem that if the conductive trace of the flexible circuit board is broken, the electric signal used for tumor electric field treatment cannot be transmitted to all the ceramic pieces, resulting in that the electrode patch cannot apply an alternating electric field to the tumor site of the patient for tumor electric field treatment, the electrode patch cannot be used, the product manufacturing yield is low, and the manufacturing cost is increased.

[0034] Reference Figure 2A With Figure 2BEach electrode unit 10 comprises a flexible plate base 11, a support plate 13 and a ceramic transducer sheet 12 arranged on both sides of the flexible plate base 11 respectively, and a male seat 15 arranged on the same side surface of the flexible plate base 11 as the ceramic transducer sheet 12. The ceramic transducer sheet 12 and the male seat 15 are located at opposite ends of the flexible plate base 11, and the ceramic transducer sheet 12 and the support plate 13 are located at the same end of the flexible plate base 11. In this embodiment, the sizes of the support plate 13 and the ceramic transducer sheet 12 are slightly smaller than the size of the flexible plate base 11.

[0035] The ceramic transducer sheet 12 is made of a high dielectric constant material, which has a conductive property of hindering the conduction of direct current and allowing the passage of alternating current, so as to ensure the safety of the user during tumor electric field treatment. The ceramic transducer sheet 12 has a through hole 121 in the center. The electrode unit 10 further comprises a temperature sensor 14 arranged on the flexible plate base 11 and located on the same side as the ceramic transducer sheet 12. The temperature sensor 14 is accommodated in the through hole 121 in the center of the ceramic transducer sheet 12, and is used to sense the temperature of the skin of the patient attached to the electrode patch 100. The temperature sensor 14 has a ground end 14A and a signal end 14B. Preferably, the temperature sensor 14 is a thermistor.

[0036] With reference to Figure 3 , three first conductive traces 114 are embedded in the flexible plate base 11. The three first conductive traces 114 include a first ground line 114A electrically connected to the ground end 14A of the temperature sensor 14 and the male seat 15, a first signal line 114B electrically connected to the signal end 14B of the temperature sensor 14 and the male seat 15 and transmitting a temperature signal, and a first AC line 114C arranged in a ring shape and electrically connected to the ceramic transducer sheet 12 and the male seat 15. The first ground line 114A and the first signal line 114B are arranged in extension along the length direction of the flexible plate base 11. The first AC line 114C is arranged in a ring shape along the periphery of the flexible plate base 11 and has a two-segment structure with the ends electrically connected at the part of the flexible plate base 11 where the male seat 15 is arranged, i.e. the male seat 15 is electrically connected to the ceramic transducer sheet 12 through the two-segment line. Therefore, when one segment of the first AC line 114C is broken due to bending, the other segment of the first AC line 114C can still transmit an electrical signal to the ceramic transducer sheet 12, ensuring the electrical reliability of the electrode unit 10, improving the product quality and reducing the product failure rate. The first ground line 114A and the first signal line 114B are located inside the ring-shaped first AC line 114C, so as to facilitate wiring and reduce the difficulty of wiring.

[0037] Specifically, the first AC line 114C is arranged in a ring shape along the periphery of the flexible plate base 1111 and includes a first AC line segment 115 arranged in a circular arc shape at the same end as the ceramic transducer sheet 12 and a second AC line segment 116 extending from the first AC line segment 115 and arranged in an inverted "Π" shape. The first AC line segment 115 is electrically connected to the ceramic transducer sheet 12 arranged on the flexible plate base 11. One end of the first AC line segment 116 is connected to the opposite two ends of the first AC line segment 115, and the other end is welded to the male seat 15 arranged on the flexible plate base 11. The electrode unit 10 is electrically connected between the ceramic transducer sheet 12 and the male seat 15 through the electrical connection of the first AC line segment 115 of the first AC line 114C of the flexible plate base 11, the first AC line segment 115 of the first AC line 114C of the flexible plate base 11 to one end of the second AC line segment 116, and the other end of the second AC line segment 116 of the first AC line 114C of the flexible plate base 11 to the male seat 15.

[0038] The second AC line segment 116 is closed at the end away from the first AC line segment 115 after extending along the length direction of the flexible plate base 11 from the opposite two ends of the first AC line segment 115. The second AC line segment 116 extends from one end of the first AC line segment 115 in a direction away from the ceramic transducer sheet 12, then extends in a direction toward the other end of the first AC line segment 115 after bending, and then extends in a direction toward the other end of the first AC line segment 115 until connected to the other end of the first AC line segment 115. The second AC line segment 116 includes a portion extending from one end of the first AC line segment 115 and arranged in an "L" shape, and a portion extending from the other end of the first AC line segment 115 and arranged in an "I" shape. The second AC line segment 116 has two portions connected to the opposite two ends of the first AC line segment 115, respectively, so that when one of the two portions is disconnected from one end of the first AC line segment 115 due to bending, the other portion can be connected to the other end of the first AC line segment 115 to ensure electrical connection between the second AC line segment 116 and the first AC line segment 115, thereby achieving good and stable electrical connection between the ceramic transducer sheet 12 and the male seat 15. That is, the second AC line segment 116 of the first AC line 114C is connected to the opposite two ends of the first AC line segment 115 arranged in a circular arc shape, so that even when the second AC line segment 116 is disconnected from one end of the first AC line segment 115 due to bending, the electrical signal can still be transmitted to the ceramic transducer sheet 12 through the connection between the second AC line segment 116 and the other end of the first AC line segment 115, ensuring the reliability of the electrical connection between the ceramic transducer sheet 12 and the flexible plate base 11 of the electrode unit 10, improving product quality, and reducing product failure rate. The first ground line 114A and the first signal line 114B are both located in the area where the first AC line 114C is arranged in a ring shape, so as to facilitate wiring and reduce wiring difficulty.

The conductive pads 111 and the first pads 112 are located at the same end of the flexible plate base 11, and the second pads 113 are located at the other end of the flexible plate base 11. The plurality of conductive pads 111 are respectively electrically connected with the first AC line segment 115 of the first AC line 114C embedded in the flexible plate base 11, and are connected in series through the arc-shaped first AC line segment 115. The flexible plate base 11 is electrically connected with the ceramic transducer sheet 12 through the electrical connection between the first AC line segment 115 of the first AC line 114C and the conductive pads 111, and the welding between the conductive pads 111 and the ceramic transducer sheet 12.

[0040] The two first pads 112 are located at the middle position surrounded by the plurality of conductive pads 111. The first pad 112 welded with the ground terminal 14A of the temperature sensor 14 is the first pad 112A, and the first pad 112 welded with the signal terminal 14B of the temperature sensor 14 is the first pad 112B. The first pad 112A is arranged at the end of the first ground line 114A located in the first AC line segment 115 of the first AC line 114C, and the first pad 112B is arranged at the end of the first signal line 114B located in the first AC line segment 115 of the first AC line 114C. The first pad 112A is electrically connected with one end of the first ground line 114A, and the first pad 112B is electrically connected with one end of the first signal line 114B. The flexible plate base 11 is electrically connected with the temperature sensor 14 through the first pad 112A connected with the first ground line 114A and the first pad 112B connected with the first signal line 114B.

[0041] The second soldering pad 113 is arranged at the opposite end of the flexible plate base 11 from the first soldering pad 112. The second soldering pad 113 is arranged at the end of the flexible plate base 11 away from the ceramic transducer 12 and is soldered to the male seat 15 to realize electrical connection between the second soldering pad 113 and the male seat 15. The second soldering pad 113 is at least three, including a second soldering pad 113A electrically connected to the first soldering pad 112A through the first ground line 114A, a second soldering pad 113B electrically connected to the first soldering pad 112B through the first signal line 114B, and at least one second soldering pad 113C electrically connected to the conductive disc 111 through the first AC line 114. The second soldering pad 113A and the first soldering pad 112A are arranged at the opposite ends of the first ground line 114A and are electrically connected through the first ground line 114A. The second soldering pad 113B and the first soldering pad 112B are arranged at the opposite ends of the first signal line 114B and are electrically connected through the first signal line 114B. The second soldering pad 113C and the conductive disc 111 are arranged at the opposite ends of the first AC line 114 and are electrically connected through the first AC line 114. The second soldering pad 113C is arranged at the end of the second AC line segment 116 of the first AC line 114C, and the conductive disc 111 is arranged on the first AC line segment 115 of the first AC line 114C. The flexible plate base 11 is soldered to the ceramic transducer 12 through the conductive disc 111 arranged on the first AC line segment 115 of the first AC line 114C, and the second soldering pad 113C arranged at the end of the second AC line segment 116 of the first AC line 114C is soldered to the male seat 15 to realize electrical connection between the male seat 15 and the ceramic transducer 12. The flexible plate base 11 is soldered to the ground end 14A of the temperature sensor 14 through the first soldering pad 112A arranged at one end of the first ground line 114A, and the signal end 14B of the temperature sensor 14 through the first soldering pad 112B arranged at one end of the first signal line 114B, and the second soldering pad 113A arranged at the other end of the first ground line 114A and the second soldering pad 113B arranged at the other end of the first signal line 114B are all soldered to the male seat 15 to realize electrical connection between the temperature sensor 14 and the male seat 15.

[0042] The second soldering pads 113 soldered to the public seat 15 are at least three, which can make the soldering between the public seat 15 and the flexible plate base 11 firm when the public seat 15 is soldered to the flexible plate base 11 through the second soldering pads 113, and ensure that the public seat 15 and the flexible plate base 11 have good electrical connection. And the conductive disc 111 is soldered to the public seat 15 through at least one second soldering pad 113C provided on the second AC line segment 116 of the first AC line 114C, which can ensure that the conductive disc 111 and the public seat 15 have stable electrical connection, so as to transmit the electrical signal for tumor treatment to the conductive disc 111 through the first AC line 114C, and then transmit the electrical signal to the ceramic transducer sheet 12 through the conductive disc 111. In the embodiment, four second soldering pads 113C soldered to the public seat 15 are respectively connected to the second AC line segment 116 of the first AC line 114C. In order to achieve the purpose of reinforcing the soldering between the public seat 15 and the flexible plate base 11, the application can also have other embodiments. For example, one of the plurality of second soldering pads 113 is connected to the first ground line 114A, one is connected to the second AC line segment 116 of the first AC line 114C, and the remaining ones are respectively connected to the corresponding first signal lines 114B one by one. For another example, one of the plurality of second soldering pads 113 is connected to the first signal line 114B, one is connected to the first AC line 114C, and the remaining ones are respectively connected to the first ground line 114A. That is, two of the plurality of second soldering pads 113 are respectively connected to two of the first ground line 114A, the first signal line 114B and the first AC line 114C, and the remaining second soldering pads 113 are connected to the remaining one of the first ground line 114A, the first signal line 114B and the first AC line 114C.

[0043] The ground signal of the temperature sensor 14 is transmitted to the corresponding second pad 113A through the first ground line 114A electrically connected with the ground terminal 14A; the temperature signal detected by the temperature sensor 14 is transmitted to the corresponding second pad 113B through the first signal line 114B electrically connected with the signal terminal 14B; and the temperature signal detected by the temperature sensor 14 is transmitted to the electric field generator 200 through the second pad 113 welded with the male seat 15, the male seat 15 inserted with the adapter plate 20, the adapter plate 20 electrically connected with the wire 30, and the wire 30 inserted with the electric field generator 200, so as to achieve the purpose that the electric field generator 200 controls the alternating current signal transmitted to the ceramic transducer 12 through the detected temperature signal, and avoids the patient's tumor surface from being scalded due to the high temperature. The AC signal generated by the electric field generator 200 is transmitted to the first AC line 114C arranged in a ring through the corresponding at least two second pads 113C, and then transmitted to the ceramic transducer 12 through the plurality of conductive discs 111 welded with the first AC line 114C, so as to apply the AC signal to the tumor part for tumor electric field treatment. The AC signal required by the ceramic transducer 12 is an alternating current signal output by the electric field generator 200. The electric field generator 200 also outputs a direct current signal to the temperature sensor 14, so that the temperature sensor 14 is connected with the ground signal and generates the temperature signal.

[0044] The support plate 13 is adhered to the side surface of the flexible plate base 11 away from the conductive disc 111 by an adhesive (not shown). The support plate 13 corresponds to the ceramic transducer 12 in the thickness direction. The temperature sensor 14 is welded at the position corresponding to the two first pads 112 of the flexible plate base, the ceramic transducer 12 is welded at the position corresponding to the plurality of conductive discs 111 of the flexible plate base 11, and the male seat 15 is welded at the position of the second pad 113 of the flexible plate base 11. The temperature sensor 14, the ceramic transducer 12, and the support plate 13 are arranged at the same end of the flexible plate base 11. When the temperature sensor 14 and the ceramic transducer 12 are welded, the support plate 13 provides strength support for the flexible plate base 11, provides a flat welding plane for the welding operation between the flexible plate base 11 and the temperature sensor 14 and the ceramic transducer 12, and improves the product yield. The reinforcing plate 16 is adhered to the end of the flexible plate base 11 where the male seat 15 is welded, and is arranged on the side surface of the flexible plate base 11 opposite to the male seat 15, so as to provide strength support for the flexible plate base 11, to facilitate the welding of the male seat 15 thereon, and to avoid the flexible plate base 11 and the male seat 15 from being bent at the welding position when the male seat 15 is inserted with or pulled out of the adapter plate 20, so as to avoid the conductive trace embedded in the flexible plate base 11 from being broken. The reinforcing plate 16 and the male seat 15 are arranged on opposite sides of the flexible plate base 11. The reinforcing plate 16 and the male seat 15 are located at the same end of the flexible plate base 11.

[0045] The adapter plate 20 is provided with at least one female seat 25 corresponding to and electrically connected with the male seat 15 of the electrode unit 10. A plurality of electrode units 10 can be respectively plugged and combined with the corresponding female seat 25 on the adapter plate 20 through the corresponding male seat 15 to form an electrode patch 100 with at least one electrode unit 10.

The plurality of female sockets 25 arranged on the branch 22 are symmetrically arranged along the longitudinal symmetry axis of the trunk 21. Two of the five female sockets 25 arranged on the two branches 22 on the same side of the trunk 21 are arranged at the end of the corresponding branch 22 in a longitudinal alignment, and the remaining three are arranged in a longitudinal alignment at a position close to the trunk 21 of the corresponding branch 22.

[0060] In this embodiment, the female sockets 25 arranged on the branches 22 are arranged on the edge of the corresponding branch 22, and the female sockets 25 arranged on the trunk 21 are arranged in a transverse alignment with the corresponding female sockets 25 arranged on the branches 22, so as to facilitate the wiring arrangement of the second conductive traces 26 of the adapter plate 20, and the female sockets 25 are connected in parallel on the adapter plate 20 through the second conductive traces 26. As shown in Figure 4 and Figure 6B The electrode units 10 connected in a detachable manner with the female sockets 25 arranged at the end of each branch 22 are arranged in a transverse group on the adapter plate 20, and the electrode units 10 connected in a detachable manner with the female sockets 25 arranged at the end of each branch 22 are arranged in a longitudinal group on the adapter plate 20. In other embodiments, since the electrode units 10 are connected in parallel on the adapter plate 20, the on-off of the AC signal, the ground signal and the temperature signal of each electrode unit 10 does not affect each other, and the number of electrode units 10 connected in a detachable manner on the adapter plate 20 is less than the number of female sockets 25 on the adapter plate 20.

[0061] In combination with Figure 4 , Figure 5A , Figure 5B and Figure 8AOne end of the wire 30 is electrically connected to the wiring portion 27 of the adapter plate 20, and the other end is provided with a plug 32. Preferably, the wire 30 is a Remo female sheathed wire. The wire 30 has a plurality of cores (not shown), and each core (not shown) is respectively welded to the corresponding fourth pad 24 on the surface of the two sides of the wiring portion 27. In this embodiment, the number of electrode units 10 of the electrode patch 100 is 13, and the number of cores (not shown) of the wire 30 is 16. Accordingly, there are cores (not shown) in the wire 30 which are welded to the fourth pads 24A, 24B, and 24C and are electrically connected, and there are cores (not shown) which are welded to the virtual pad 24D and are not electrically connected. The periphery of the welding position of the wire 30 and the wiring portion 27 is also provided with a layer of heat shrink sleeve 31 for sealing and insulating protection of the welding position of the adapter plate 20 and the wire 30, to prevent the welding position of the adapter plate 20 and the wire 30 from breaking, and also to prevent dust and water.

The fourth pad 24 also includes a fourth pad 24E located at the end of the wiring portion 27, which can be welded to the shielding mesh wire (not shown) of the wire 30 to shield the wire 30 from external signal interference with the signals transmitted by the plurality of cores (not shown) of the wire 30. The fourth pad 24E for shielding and the fourth pad 24A for transmitting a ground signal are both connected to the second ground line 26A of the second conductive trace 26.

The adapter wire 33 is detachably connected to the wire 30, which not only allows the length of the wire 30 between the electric field generator 200 or the adapter 300 to be increased or decreased as needed, but also allows the wire 30 welded to the adapter plate 20 to be scrapped when the electrode patch 100 needs to be replaced, without scrapping the adapter wire 33, thereby reducing costs and avoiding unnecessary waste. The number of cores (not shown) of the adapter wire 33 is the same as the number of cores (not shown) of the wire 30, and each core (not shown) of the adapter wire 33 corresponds to one core (not shown) of the wire 30.

The two second perforations 51B respectively correspond to the positions where the branch 22 extends laterally from the stem 21 of the adapter plate 20, so that part of the heat of the electrode patch 100 can be transferred from the adapter plate 20 to the external environment through the backing 40 to achieve the purpose of heat dissipation. The two second perforations 51B are both long holes. The size of each first perforation 51A is slightly larger than the size of the end of the electrode unit 10 to which the ceramic transducer sheet 12 is welded. Preferably, the support 50 is foam.

Three adhesive members 60 are provided in a transverse parallel manner, and each covers three ceramic transducer sheets 12 of the electrode unit 10. Two adhesive members 60 are provided in a longitudinal parallel manner, and each covers two ceramic transducer sheets 12 of the electrode unit 10. The two adhesive members 60 provided in a longitudinal parallel manner are distributed on both sides of the three adhesive members 60 provided in a transverse parallel manner.

[0067] The electrode patch 100 can further include at least one release paper 70. The release paper 70 is located on the side of the adhesive 60 away from the backing 40 and covers the corresponding part of the adhesive 60 and the backing 40 to protect the adhesive 60 and the backing 40 from contamination. In this embodiment, the electrode patch 100 has two release papers 70. The two release papers 70 collectively cover the adhesive 60 and the backing 40.
