Description

Electrode plate and electric field treatment system

Technical Field

The utility model relates to the field of medical equipment, in particular to an electrode slice for tumor electric field treatment and an electric field treatment system.

Background

At present, the treatment modes of tumors mainly comprise operation, radiotherapy, chemotherapy and the like, but have corresponding defects, such as side effects caused by radiotherapy and chemotherapy, and normal cells can be killed. The use of electric fields to treat tumors is also one of the leading edges of current research and development, and tumor electric field treatment is a method for producing a tumor by using an electric field generator to interfere with the mitotic processes of tumor cells through low-intensity, medium-high-frequency and alternating electric fields. Research shows that the electric field treatment has obvious effect in treating glioblastoma, non-small cell lung cancer, malignant pleural mesothelioma and other diseases, and the electric field applied by the treatment method can influence the aggregation of tubulin, prevent spindle body formation, inhibit mitosis process and induce cancer cell apoptosis.

The existing tumor electric field treatment system mainly comprises an electric field generating device for generating an alternating electric signal for tumor electric field treatment, an adapter electrically connected with the electric field generating device and a plurality of pairs of electrode plates electrically connected with the electric field generating device through the adapter. The electric field generating device transmits alternating electric signals for tumor electric field treatment to each electrode plate through the adapter, and then the alternating electric field is applied to the tumor part of the patient through the electrode plates to carry out tumor electric field treatment. The application of the tumor therapeutic electric field to the patient's body will collect heat at the location where the electrodes are applied to the skin, and therefore the temperature of the surface of the patient's tumor site to which the electrodes are applied will be monitored in real time. When the body surface temperature is too high, the electric field intensity is required to be adjusted in time, and low-temperature scalding of the skin of a patient caused by the too high temperature is avoided.

Each electrode sheet is provided with a plurality of electrode units. The existing electrode sheet is provided with a thermistor element on some electrode units corresponding to part of the electrode sheet, and each thermistor element is connected in parallel. The resistance value of the thermistor element changes with a temperature change, and the resistance value change of the thermistor element corresponds to a temperature change of the body surface to which the electrode unit is attached. Further, 8 thermistor elements are arranged on each electrode plate, and a cable with 10 core wires is connected between each electrode plate and the adapter. Each electrode sheet transmits the resistance values of 8 thermistor elements through the cable of 10-core wires. That is, the 10-core wire cable includes 8 signal output lines for transmitting the temperature signal sensed by the thermistor element to the adaptor, and further includes 1 ground line connected to each thermistor element and 1 AC signal line connected to each electrode unit. The number of thermistor elements on the electrode pads is no more than 8, regardless of the number of electrode units on the electrode pads, and the electrode pads are connected with the adapter by a cable configured with 10-core wires. For example, if 8 thermistor elements are provided on an electrode sheet having 9 electrode units, then 8 individual wires are required to transmit signals of the 8 thermistor elements, and the coverage of the thermistor elements in the electrode sheet is 89% (8/9≡0.89). For another example, if 8 thermistor elements are provided in an electrode sheet having 13 electrode units, the coverage of the thermistor elements in the electrode sheet is 62% (8/13+.0.62). For another example, 8 thermistor elements are arranged on an electrode sheet with 20 electrode units, at this time, the coverage rate of the thermistor elements in the electrode sheet is 40% (8/20 is approximately equal to 0.4), and the temperature of more than half of the electrode units cannot be monitored, so that the condition that the skin of a patient is scalded at low temperature due to incomplete monitoring is easy to occur. If it is required to provide a thermistor element on each electrode unit of the electrode sheet, more wires are required for the cables because the thermistor elements are connected in parallel with each other. However, this causes the cable to become thicker and the softness of the cable to become hard, increasing the difficulty of fixing the cable. Meanwhile, the overall weight of the electrode plate is increased due to the fact that the number of wires of the cable is increased, the adhesion effect between the electrode plate and the corresponding body surface of the tumor part of the patient can be affected, the load of the patient can be increased, and discomfort is caused.

Accordingly, there is a need for an improved electrode sheet and electric field therapy system that fully monitors the temperature of the patient's body surface to which each electrode unit in the electrode sheet is correspondingly applied while reducing the number of wires of the cable between the electrode sheet and the adapter.

That is, when the number of the electrode units 12 of a group of electrode units 12 is the same as the number of the signal output lines 19, each signal output line 19 is electrically connected to a signal end (not numbered) of the temperature detector 14 of a different one of the electrode units 12 of the group of electrode units 12; when the number of the electrode units 12 of a group of electrode units 12 is less than the number of the signal output lines 19, there is at least one signal output line 19 that is not electrically connected to the signal end (not numbered) of the temperature detector 14 of the electrode unit 12, and the remaining signal output lines 19 are respectively electrically connected to the signal end (not numbered) of the temperature detector 14 of a different electrode unit 12 of the group of electrode units 12.

In this embodiment, the AC signal line 17, the ground line 18 and the signal output line 19 embedded in the flexible circuit board 11 are 10 lines, and when each electrode unit 12 is configured with the temperature detector 14 to perform temperature detection, the number of wires of the first cable 15 is reduced by the above line design, so as to avoid thickening the cable, hardening the softness of the cable and increasing the difficulty of cable fixing; and meanwhile, the adhesion effect between the electrode plate 10 and the corresponding body surface of the tumor part of the patient is prevented from being influenced by the increase of the number of wires of the first cable 15. The ground wire 18 and the signal output wire 19 embedded in the flexible circuit board 11 are 9 lines in total. Specifically, in this embodiment, the ground line 18 embedded in the flexible circuit board 11 is 4 lines, and the signal output line 19 is 5 lines.

In the present embodiment, the electrode elements 13 in each electrode unit 12 are connected in parallel to the AC signal line 17. In other embodiments, the electrode elements 13 in each electrode unit 12 are connected in series to the AC signal line 17.

The plurality of sets of electrode units 12 are arranged on the flexible wiring board 11 at intervals substantially in the form of a two-dimensional array. Referring to fig. 2, the electrode sheet 10 in the present embodiment has 4 sets of electrode units 12, each set of electrode units 12 having 5 electrode units 12. The electrode sheet 10 in the present embodiment has 20 electrode units 12. The 20 electrode units 12 may be arranged in a two-dimensional array.

Among the 20 electrode units 12 arranged in four rows and six columns, a group of electrode units 12 is formed by 5 electrode units 12 that are close to each other, and the 20 electrode units 12 are grouped into four groups of electrode units 12, so that the wiring design of the AC signal line 17, the ground line 18, and the signal output line 19 in the flexible wiring board 11 is facilitated. The 20 electrode units 12 of the electrode sheet 10 may also be arranged in four rows and five columns. Each row of electrode sheets 10 has 5 electrode units 12, constituting a group of electrode units 12. In other embodiments, the 20 electrode units 12 may be arranged in other ways as well. Of course, in other embodiments, the electrode sheet 10 may have other numbers of electrode units 12. In summary, the implementation of the present utility model is not limited by the number and arrangement of the electrode units 12 of the electrode sheet 10.

Each electrode unit 12 comprises an electrode element 13 and a temperature detector 14. In the embodiment shown in fig. 2, the electrode element 13 may be a dielectric element, such as a dielectric ceramic sheet. The temperature detector 14 may be a thermistor element, although in other embodiments the temperature detector 14 may be a temperature sensor other than a thermistor. Each electrode element 13 has a through hole (not numbered) provided therethrough, and each electrode element 13 has a corresponding temperature detector 14 housed therein. Each electrode unit 12 may also include a diode 16. The diode 16 is connected in series with the temperature detector 14 of the same electrode unit 12, which can prevent reverse inflow of current to prevent detection signals from other electrode units 12 from affecting the temperature detector 14.

As shown in fig. 2, the electrode sheet 10 of the present embodiment includes 4 ground lines 18, each ground line 18 being used to ground the ground terminals (not numbered) of the temperature detectors 14 of the same group of electrode units 12. The 4 ground lines 18 of the electrode sheet 10 are a first ground line 18-1, a second ground line 18-2, a third ground line 18-3, and a fourth ground line 18-4, respectively. Of the four groups of electrode units 12 of the electrode sheet 10, the first group of electrode units 12 are electrode units 12-1 to 12-5, the second group of electrode units 12 are electrode units 12-6 to 12-10, the third group of electrode units 12 are electrode units 12-11 to 12-15, and the fourth group of electrode units 12 are electrode units 12-16 to 12-20. Specifically, the first ground line 18-1 is used to ground the first group of electrode units 12 (i.e., electrode units 12-1 through 12-5); the second ground line 18-2 is used to ground the second group of electrode units 12 (i.e., electrode units 12-6 to 12-10); the third ground line 18-3 is used to ground the third group of electrode units 12 (i.e., electrode units 12-11 to 12-15); the fourth ground line 18-4 is used to ground the fourth set of electrode units 12 (i.e., electrode units 12-16 through 12-20). It should be noted that these ground lines 18 may be selectively closed or opened, which may be achieved by connecting each ground line 18 in series with a switch, respectively, as will be described in more detail below. The above-described "grounding the electrode unit 12" may refer to grounding the ground (not numbered) of the temperature detector 14 in the electrode unit 12. The diode 16 is connected in series with the temperature detector 14 of the same electrode unit 12 and is grounded together. In short, each ground line 18 shorts the ground terminals of the temperature detectors 14 of all the electrode units 12 in each group of electrode units 12 to ground.

As shown in fig. 2, the electrode sheet 10 of the present embodiment further includes 5 signal output lines 19, one end of each signal output line 19 is connected to at most one electrode unit 12 of each group of electrode units 12, respectively, and the other end thereof is connected to an adapter 20 for receiving a detection signal. That is, for each group of electrode units 12, each signal output line 19 may be selectively connected to one of the electrode units 12 or not connected to any one of the electrode units 12 in the group, and the electrode units 12 to which each signal output line 19 is connected are located in different groups from each other so as to avoid the subsequent output of a repeated signal by the signal output line 19. Specifically, the 5 signal output lines 19 of the electrode pad 10 include a first signal output line 19-1, a second signal output line 19-2, a third signal output line 19-3, a fourth signal output line 19-4, and a fifth signal output line 19-5. One end of the first signal output line 19-1 is connected to signal ends (not numbered) of the temperature detectors 14 of the electrode units 12-1, 12-6, 12-11, 12-16, respectively; one end of the second signal output line 19-2 is connected to signal ends (not numbered) of the temperature detectors 14 of the electrode units 12-2, 12-7, 12-12, 12-17, respectively; one end of the third signal output line 19-3 is connected to signal ends (not numbered) of the temperature detectors 14 of the electrode units 12-3, 12-8, 12-13, 12-18, respectively; one end of the fourth signal output line 19-4 is connected to signal ends (not numbered) of the electrode units 12-4, 12-9, 12-14, and 14 of the temperature detector 12-19, respectively; one end of the fifth signal output line 19-5 is connected to signal ends (not numbered) of the temperature detectors 14 of the electrode units 12-5, 12-10, 12-15, 12-20, respectively. In short, each signal output line 19 shorts the signal ends of the temperature detectors 14 of the electrode units 12 located in different groups and corresponding to each other and is used for connection to an external device.

The AC signal line 17, the multiple-path ground line 18, and the multiple-path signal output line 19 are all lines embedded in the flexible wiring board 11. The flexible circuit board 11 is electrically connected to the first cable 15. The AC signal lines 17, the multiple ground lines 18, and the multiple signal output lines 19 embedded in the flexible circuit board 11 are electrically connected to a corresponding one of the wires in the first cable 15.

During application of the electrode sheet 10, the detection signal of each temperature detector 14 in the 20 electrode units 12 can be obtained in a time-sharing manner by using only 5 signal output lines 19.

As shown in fig. 2, each set of the analog-to-digital converter 22 includes 5 detection channels, which are a first detection channel a, a second detection channel B, a third detection channel C, a fourth detection channel D, and a fifth detection channel E, respectively.

The electric field generator 30 is further configured to adjust the voltage of the alternating electrical signal provided to the electrode elements 13 in the plurality of groups of electrode units 12 of the electrode sheet 10 in accordance with the received digital signal. For example, when any one of the received digital signals exceeds a preset threshold, it indicates that the temperature of at least one electrode element 13 in the electrode sheet 10 exceeds a preset threshold temperature (for example, 41 ℃ and 42 ℃), and at this time, the voltage of the ac electric signal output by the electric field generator 30 may be appropriately reduced, so as to avoid the electrode sheet 10 from causing low-temperature scalding to the skin of the patient. The preset threshold temperature and the preset threshold value can be determined according to related experimental data. The communication transceiver 26 is controlled by the controller 21 and serially transmits the digital signals converted by the plurality of sets of analog-to-digital converters 22.

The operation of the electric field therapy system 1 of the present embodiment will be described in detail with reference to fig. 2 and 3.

Specifically, each channel of each set of the analog-to-digital converters 22 collects only the detection signal of the temperature detector 14 of the corresponding one of the electrode pads 10 at the same time, and the detection signal may be a voltage value. Only 1 switch 24 is on at the same time with 4 switches 24, and the other 3 switches are off. So configured, each set of analog-to-digital converters 22 may only collect voltage values for all temperature detectors 14 of one set of electrode units 12 shorted to a ground line 18 corresponding to a switch 24 that is turned on. Specifically, when the switch 24-1 is closed and the switches 24-2, 24-3 and 24-4 are all opened, the temperature detectors 14 of the electrode units 12-1 to 12-5 are electrified, the temperature detectors 14 of the electrode units 12-6 to 12-20 are powered off, the temperature detectors 14 of the electrode units 12-1, 12-6, 12-11 and 12-16 are short-circuited on the first detection channel A in the analog-digital converter 22, and since the grounding ends of the temperature detectors 14 of the electrode units 12-6, 12-11 and 12-16 are all open, the diode 16 connected in series with the temperature detector 14 is arranged on each electrode unit 12, the resistance value of the temperature detector 14 of the electrode unit 12-1 is not affected, so that only the temperature detector 14 of the electrode unit 12-1 effectively operates on the first detection channel A of the analog-digital converter 22, and the collected detection signal (voltage value) is the voltage value of the temperature detector 14 of the electrode unit 12-1. Similarly, the voltage value detected on the second detection channel B in the analog-to-digital converter 22 is the voltage value of the temperature detector 14 of the electrode unit 12-2. The voltage value detected on the third detection channel C in the analog-to-digital converter 22 is the voltage value of the temperature detector 14 of the electrode unit 12-3. The voltage value detected on the fourth detection channel D in the analog-to-digital converter 22 is the voltage value of the temperature detector 14 of the electrode unit 12-4. The voltage value detected on the fifth detection channel E in the analog-to-digital converter 22 is the voltage value of the temperature detector 14 of the electrode unit 12-5.

The controller 21 and the multiple analog-to-digital converters 22 may automatically perform operations by pre-programmed program code, for example, the controller 21 first closes the switch 24-1 of the multiple switches 24, opens the remaining switches 24-2 to 24-4, during which the multiple analog-to-digital converters 22 acquire the detection values of the respective detection channels and store them in the additionally provided memory, and then after a predetermined time interval, the controller 21 again closes the switch 24-2 of the multiple switches 24, opens the switches 24-1, 24-3, and 24-4, during which the multiple analog-to-digital converters 22 acquire the detection values of the respective detection channels. Thus, each switch 24 in the plurality of groups of switches 24 is turned on individually in turn, and detection values of all the temperature detectors 14 on the electrode sheet 10 can be obtained. By this operation, the detection values of all the temperature detectors 14 on at least one pair of electrode pads 10 are obtained.
