Description

Electric field therapy system

Technical Field

The utility model relates to the technical field of medical treatment, in particular to an electric field treatment system for tumor treatment.

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 of the thermistor element changes with the temperature change, and the resistance change of the thermistor element corresponds to the 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, 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). Further, if only 8 thermosensitive electrode elements are distributed on 8 electrode units of the 20 electrode units on the electrode plate with 20 electrode units, and 12 electrode units are not covered with thermosensitive resistor elements, more than half of the electrode units cannot monitor temperature, and low-temperature scald of the skin of a patient is easy to occur due to incomplete monitoring.

Accordingly, it is desirable to provide an improved electric field therapy system for comprehensively monitoring the temperature of the patient's body surface to which each electrode unit in the electrode pad is applied.

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 of the present application, the temperature detector 14 may be a temperature sensor other than a thermistor. Each electrode element 13 has a through hole (not shown) provided therethrough in the middle thereof, and each electrode element 13 has a corresponding temperature detector 14 accommodated therein. Each electrode unit 12 may also include a diode 16.

That is, the signal terminals of the temperature detectors 14 of the electrode units 12 of different groups and not corresponding are respectively connected to an external device through the respective different signal output lines 19, and the ground terminals of the temperature detectors 14 of the electrode units 12 of different groups and not corresponding are respectively short-circuited to ground through the respective different ground lines 18.

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 plurality of ground lines 18, and the plurality of signal output lines 19 embedded in the flexible circuit board 11 are electrically connected to a corresponding one of the cores in the first cable 15, respectively.

In the application process 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 and 4 grounding lines 18. Specifically, each of the plurality of ground lines 18 of the electrode sheet 10 may be individually turned on in turn, and the detection signal of the temperature detector 14 of each of the electrode units 12 of the group of electrode units 12 grounded by the ground line 18 may be acquired in the on state of each of the ground lines 18. So that the detection signals of the temperature detectors 14 of all the electrode units 12 of the electrode sheet 10 can be obtained after the operation of sequentially conducting a corresponding one of the ground lines 18 a plurality of times. In the related art, since each temperature detector 14 outputs the detection signal at the same time, 20 independent signal output lines 19 are required to detect the temperatures of all the electrode elements 13, so that the wiring difficulty of the flexible circuit board 11 is increased, the processing is difficult, and the cost is increased; and the corresponding first cable 15 is necessarily required to contain 22 cores (including the additional 1 ground line 18 and 1 AC signal line 17), which greatly increases the weight of the electrode sheet 10 as a whole and increases the manufacturing cost of the first cable 15. As can be seen from the embodiment of fig. 2, the first cable 15 of the electrode slice 10 of the present application only includes 10 cores (not shown), namely, 4 cores (not shown) electrically connected to the ground wire 18, 5 cores (not shown) electrically connected to the signal output wire 19, and 1 core (not shown) electrically connected to the AC signal wire 17, so that the overall weight of the electrode slice 10 is effectively controlled, the adhesion effect between the electrode slice 10 and the corresponding body surface of the tumor part of the patient is prevented from being affected by the increase of the number of the cores (not shown) of the first cable 15, and the processing cost is reduced; in addition, only the 1-channel AC signal line 17, the 5-channel signal output line 19 and the 4-channel grounding line 18 are arranged on the flexible circuit board 11, so that signals detected by the temperature detectors 14 of the 20 electrode units 12 can be obtained, the temperature of all the electrode units 12 of the electrode plate 10 can be comprehensively monitored, and further, the alternating current signals applied to the electrode plate 10 are controlled through the temperature signals of the electrode units 12, so that low-temperature scalding of the skin surface of a patient to which the electrode unit 12 of the electrode plate 10 is attached due to the fact that the temperature of the electrode unit 12 of the electrode plate 10 is too high is avoided, meanwhile, the wiring design of the flexible circuit board 11 is simplified, and the manufacturing cost is further reduced.

In the present embodiment, each electrode sheet 10 may further include a first connector 40.

The first connector 40 is provided in the form of a plug, facilitating quick installation and removal of the electrode pads 10 and the adapter 20, and when one of the electrode pads 10 fails, the failed electrode pad 10 can be replaced with another electrode pad 10.

The number of the grounding wires 18 embedded in the flexible circuit board 11 is related to the number of groups divided by the plurality of electrode units 12 assembled on the flexible circuit board 11, that is, the number of the grounding wires 18 is the same as the number of groups of the electrode units 12 of the electrode sheet 10. The number of signal output lines 19 embedded in the flexible wiring board 11 is related to the number of electrode units 12 in each group of the electrode pads 10. Specifically, the number of signal output lines 19 embedded in the flexible wiring board 11 is related to one set of electrode units 12 having the largest number of electrode units 12 among the respective sets of electrode units 12. Specifically, the number of signal output lines 19 embedded in the flexible wiring board 11 is the same as the total number of electrode units 12 in a group having the largest number of electrode units 12. The total number of the ground lines 18 and the signal output lines 19 is less than the number of the temperature detectors.

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, and the range can be 37-42 ℃. The communication transceiver 26 is controlled by the controller 21 to serially transmit the digital signals converted by the plurality of sets of analog-to-digital converters 22.

The working principle of the electric field therapy system 1 of the present application will be described in detail below with reference to fig. 2 and 3.

Specifically, each detection channel of each set of analog-to-digital converters 22 collects only the detection signal of a corresponding one of the temperature detectors 14 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 one 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 shorted on the first detection channel A in the analog-digital converter 22, and because the grounding ends of the temperature detectors 14 of the electrode units 12-6, 12-11 and 12-16 are all disconnected, 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 acquired 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 acquired 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 preprogrammed program codes, for example, the controller 21 first turns on the switch 24-1 of the multiple switches 24 and turns off the remaining switches 24-2 to 24-4, during which the multiple analog-to-digital converters 22 obtain the detection values of the respective detection channels and store them in the additionally provided memory, and then after a preset time interval, the controller 21 turns on the switch 24-2 of the multiple switches 24 and turns off the switch 24-1, the switch 24-3 and the switch 24-4, during which the multiple analog-to-digital converters 22 obtain 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 the 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.
