It has been found that during electric field therapy, the host device generates electric field energy that is distributed via the junction box to the electrode patches, which couple the electric field energy into the body to apply an alternating electric field to the tissue region where the tumor is located.

As shown in fig. 1, a tumor electric field therapeutic apparatus related to the related art is provided with two pairs of electric field patches, and the current common mode is that two pairs of electric field patches are alternately switched to output an electric field. Each pair of electric field patches consists of two pieces, and the electric field patches are applied on the cranium in a manner of being basically symmetrical, and the typical structure of each pair of electric field patches is shown in fig. 2, and corresponds to the front part (corresponding to the N1 jack connected with fig. 1), the rear part (corresponding to the P1 jack connected with fig. 1), the left side (corresponding to the N2 jack connected with fig. 1) and the right side (corresponding to the P2 jack connected with fig. 1) of the cranium of a user respectively.

The electrode patches are electrically connected with the junction box, and the junction box of the tumor electric field therapeutic apparatus has the main function of distributing electric field energy to the electrode patches, and temperature data of the electrode patches are also transmitted to the junction box through the connecting cable. The junction box is provided with the sockets corresponding to the number of the electrode patches, and the electrode patches are used in pairs, so that when the electrode patches are inserted into the junction box, the direction of the electrode patches needs to be distinguished, the corresponding junction box sockets are inserted, the process is complicated, a patient can easily misinsert the sockets, and the machine can be abnormally operated to stop, so that the treatment is influenced.

To at least partially solve one or more of the above-mentioned problems, and other potential problems, the present disclosure provides an electric field output device and method, an electric field treatment apparatus, to automatically determine the identity of the output without requiring a user to discern the electrode patch direction, ensuring a therapeutic effect.

For ease of understanding the embodiments of the present disclosure, the electric field therapy apparatus provided by the embodiments of the present disclosure will be described in detail first. As shown in fig. 3, a schematic diagram of an electric field treatment apparatus according to an embodiment of the present disclosure is provided, where the electric field treatment apparatus mainly includes a host device 31, an electric field output device 32, and an electrode patch 33.

The electric field output device 32 can automatically determine the identification information of the output end, and the output end is electrically connected with the electrode patch 33, so that the direction (namely the N direction and the P direction) of the electrode patch 33 can be automatically determined, the problem that in the related art, when the electrode patch is inserted into the junction box, a patient easily misoperates and misplaces the jack or further causes abnormal machine operation to stop due to the fact that the electrode patch direction is required to be distinguished in the related art is avoided, the problem of plug-and-play is avoided, the automatic distinguishing of the electrode patch direction is not required to be carried out by the patient, the operation is simpler, and the practicability is better; on the other hand, in each signal output period, multiple alternating signals can be output to multiple electrode patches through multiple output ends, that is, the electric field output device 32 can perform electric field switching of one period when receiving a signal of one period, so as to realize multi-direction electric field switching, for example, under the condition that 8 periodic signals are determined, 8-direction electric field switching can be determined, and compared with the related art, the electric field action range of the electric field treatment device is obviously improved when only front-back and left-right electric field switching is supported, so that the treatment effect is better.

Considering the electric field output device 32 as a key component of the above-described electric field treatment apparatus, the operation principle of the electric field output device 32 will be explained with emphasis on the following two aspects.

In the first aspect, as shown in fig. 4, the electric field output device 32 provided in the embodiment of the present disclosure mainly includes an output module 321, a measurement module 322, and an identification module 323; wherein:

an output module 321 including a plurality of outputs; the output end is used for electrically connecting the electrode patch, and the output module 321 outputs an alternating signal to the electrode patch through the output end;

the measurement module 322 is electrically connected with the output ends and is used for testing the electric signal of the loop between any two output ends; the method comprises the steps of,

the identification module 323 is electrically connected with the measurement module 322 and is used for determining the identification information of the output ends according to the electric signal of the loop between any two output ends measured by the measurement module 322;

the output module 321 outputs a corresponding electrical signal to the output terminal according to the identification information of the output terminal.

In order to facilitate understanding of the electric field output device 32 provided in the embodiments of the present disclosure, a simple description of an application scenario of the device is provided next. The electric field output device 32 in the embodiments of the present disclosure may be mainly applied in the field of electric field therapy, and in particular may be adapted to electrode patches to form alternating electric field signals for the treatment of tumors.

The electric field output device may be a functional device integrated into the junction box, in which case the output terminal may correspond to a socket provided on the junction box, and the electric field output device may be provided in the host device, so that in the case where a socket is provided on the host device, the socket may be used as the output terminal. In practical applications, the electric field output device herein may be applied to the electric field treatment apparatus in other ways, and is not particularly limited herein. In order to better illustrate the existing electric field therapy apparatus shown in fig. 1, a jack of a junction box is used as an output terminal.

Considering the problem that the insertion direction of the electrode patch on the junction box cannot be well distinguished, which may cause equipment abnormality in the related art, an electric field output scheme for automatically identifying the insertion direction of the electrode patch by combining the cooperation of the output module 321, the measurement module 322 and the identification module 323 is provided, so that the complexity of using the equipment is remarkably reduced.

Considering that the characteristics of the electrical signals corresponding to different electrode patches are different, based on this, the electric field output device provided in the embodiment of the disclosure may test the electrical signals between the output ends corresponding to different electrode patches based on the measurement module 322 in advance, then determine the identification information of the output end based on the test result, and take the sockets arranged on the junction box as the output ends as examples, so that the electrode patches corresponding to different sockets in different positions can be determined, and then output corresponding electrical signals to the output ends, thereby realizing electric field treatment.

The specific number of the output terminals is not limited, and is usually an even number, and may be increased with the number of the electrode patches. Taking skull application as an example, the number of the electric field patches can be four, the front part, the rear part, the left side and the right side of the skull of the user can be correspondingly applied, and the four electric field patches are correspondingly connected with corresponding output ends. Once the identification information of the output terminals is determined, that is, the electrode patch to which position the electrode patch connected to each output terminal corresponds is determined, for example, in the case where the identification information of one output terminal is determined to be 1, it can be determined that the output terminal corresponds to the N terminal of the front portion of the user's skull, so that the corresponding electric signal can be given to achieve effective electric field treatment. Four more outputs are illustrated below.

In the process of determining the identification information of the output ends, firstly, a current measuring unit included in the measuring module 322 can be used for measuring a current value of a loop between any two output ends, and a voltage measuring unit included in the measuring module 322 can be used for measuring a voltage value of the loop between any two output ends; then, the identification module 323 can calculate and obtain the impedance value of the loop between any two output ends according to the tested current value and voltage value; identification information of the corresponding output terminal is determined according to the impedance value. This is mainly to take into account that different application positions generally have different impedance values, and still taking a skull application mode as an example, generally, the impedance between the front electrode patch and the rear electrode patch of the skull is larger than the impedance between the left electrode patch and the right electrode patch, and the impedance between the two adjacent electrode patches is the lowest, so that the output end can be identified based on the characteristic.

In practical application, the detection mode can be performed after the power-on, the host device outputs a weaker electric signal to any two output ends in turn, and is used for detecting impedance values between the two electrode patches, sorting is performed according to the detected impedance values, two groups (corresponding to the first group of output ends connected with the front and rear skull patches) with the largest impedance are selected, and the other two output ends are left and right groups (corresponding to the second group of output ends connected with the left and right skull patches).

Here, to further ensure recognition accuracy, periodic detection may be performed by the measurement module 322 to determine a final recognition effect according to the periodic detection result. The measurement module 322 is capable of periodically detecting a first impedance difference between any two output terminals and a second impedance difference between the first set of output terminals and the second set of output terminals after determining the identification information of the plurality of output terminals, so that the control output terminal outputs an electrical signal in the normal mode when it is determined that the first impedance difference meets a first measurement condition and the second impedance difference meets a second measurement condition.

It should be noted that, the current difference value in the embodiment of the disclosure is largely characterized by the magnitude of the impedance difference value between the electrode patches, and the larger the current difference value is, the smaller the current difference value is, the larger the impedance difference value is, in this case, the larger the current difference value is, and in addition, the preliminary determination can be performed by combining the current difference value corresponding to the resistance difference value, and the normal output mode can be entered under the condition that the related condition is satisfied, and the prompt can be performed based on the prompt module under the condition that the related condition is not satisfied, that is, the prompt module can generate the prompt information for manually determining the electrode patch identifier under the condition that the first measurement condition or the second measurement condition is determined not to be satisfied.

In practical application, once the identification of the electrode patches is automatically identified after the power-on, the four electrode patches can be respectively numbered A, B, C, D, and then 5-10 switching periods can be continuously output in the grouping mode. And when the first measurement condition and the second measurement condition are determined to be met simultaneously (for example, the change of two impedance values detected in each period is less than 2 percent and the difference of the two impedance values is greater than 10 percent), determining that the detection is correct, and entering a normal output mode. If the impedance change is larger or the difference value is less than 10% in the detection mode, the output is stopped, prompt information is sent out, and the electrode patch direction is manually determined, so that potential safety hazards caused by patch abnormality identification are avoided.

It can be known that, the embodiment of the disclosure automatically identifies the electrode patch, can effectively solve the problem that the electrode patch is excessively complicated to insert into the junction box, can not generate the problem that the operation of equipment is abnormal due to misplug of the electrode patch no matter how the electrode patch is inserted, and ensures the safety of the equipment.

The output module 321 in the embodiment of the disclosure further includes an N output end and a P output end that output alternating signals, where the N output end is configured to output an electrical signal to two output ends of the four output ends according to the identification information; the P output end is used for outputting an electric signal to the other two output ends in the four output ends according to the identification information. Here, taking four output ends applied to the skull as an example, the N output ends can output an electrical signal to the electrode patch at the front part of the skull corresponding to the application position, and can also output an electrical signal to the electrode patch at the left side of the skull corresponding to the application position, and similarly, the P output ends can correspondingly output electrical signals to the electrode patches at the rear part and the right side of the skull, which will not be described herein.

For better on-off control of the output end, the output module 321 may further include an output switch circuit, which is used for controlling on-off of the N output end and the output end; and the control unit is used for controlling the on-off of the P output end and the output end; in addition, the output module 321 may also receive a control signal sent by the main control chip through the output control circuit, and control the on-off of the output switch circuit according to the control signal. Based on the on-off control mechanism, different output ends can be well controlled to output electric signals to different electrode patches according to the appointed electric signals, so that a better treatment effect is realized.

In a second aspect, the electric field output device 32 provided in the embodiment of the present disclosure mainly includes an output module for outputting a plurality of alternating signals to a plurality of electrode patches through a plurality of output terminals in each signal output period.

Considering that the connection between the junction box and the electrode patch is realized in a fixed socket connection mode in the related art, the formed electric field direction is insufficient to solve various complex tumor treatment scenes at present, and therefore, the embodiment of the disclosure provides an electric field output device supporting multiple directions so as to expand the acting direction of the electric field and improve the practicability.

The output module in the embodiment of the disclosure comprises an N output end and a P output end for outputting alternating signals; the N output end is electrically connected with any plurality of output ends in the four output ends, the P output end is electrically connected with any plurality of output ends in the four output ends, a plurality of output matched sets are formed, each output matched set consists of a first output end electrically connected with the N output end and a second output end electrically connected with the P output end, and the first output end and the second output end belong to different output ends;

In practical application, the output module can realize the on-off of the N output end and the first output end and the on-off of the P output end and the second output end through the output switch circuit and the output control circuit, and realize the electric field switching of a plurality of output matching groups (corresponding to a plurality of groups of electrode patches) in multiple directions.

Here, the number of electrode patches may be four, six, eight, or the like, and four electrode patches 33 are exemplified in the following in consideration of the wide application of the electric field treatment apparatus for skull application.

In order to facilitate understanding of the operation principle of the electric field output device described above, an example will be described below with reference to fig. 5. As shown in fig. 5, the total electrode patch may include four electrode patches (corresponding to electrode patch a, electrode patch B, electrode patch C, and electrode patch D), four output terminals may correspond to socket 1, socket 2, socket 3, and socket 4, respectively, the N output terminal corresponds to an N terminal output (WaveOut N), and the P output terminal corresponds to a P terminal output (WaveOut P).

The four electrode patches in the embodiment of the disclosure can form six situations in a combined mode, the WaveOut N and the WaveOut P are two output ends of a host signal, and the two output ends are output together to form at least six alternating electric field signals.

Three paths of change-over switches can be respectively configured at a P port (corresponding to a P output end) and an N port (corresponding to an N output end), signals can be output to a jack 1, a jack 2 and a jack 3 in the upper diagram by the P port, and signals can be output to the jack 2, the jack 3 and the jack 4 in the upper diagram by the N port. Wherein the jack 2 and the jack 3 can be adjusted to be N-end output or P-end output, thereby realizing the function that any two electrode patches can be combined into a pair.

When the main control chip outputs a control signal, the output control circuit can control the on-off of the output switch circuit, so that the output of the output ports of the N end and the P end of the output switching circuit is controlled.

It can be known that, the electric field output device provided by the embodiment of the present disclosure may support multi-directional electric field switching through the cooperation of the output control circuit and the output switch circuit, as shown in fig. 6 (a) to 6 (h), and the electric field direction can be extended to 8 directions by using the electric field output device provided by the embodiment of the present disclosure.

It should be noted that, the application of two sets of electrode patches as a skull patch is only a specific example, in practical application, there may be more sets of electrode patches, corresponding application positions may be separately provided, and more sets of electrode patches mean that more electric field directions may be expanded, and at the same time, application of an adaptive alternating electric field may be performed in combination with the application positions, so as to achieve a better therapeutic effect.

In order to achieve a better treatment effect, the electric field output devices provided in the two aspects can be combined in practical application, so that electric field treatment matched with multi-directional electric field switching is realized under the condition that the direction of the electrode patch is automatically identified.

Based on the electric field output device provided in the foregoing embodiments, the embodiments of the present disclosure further provide an electric field treatment device, where a host device of the electric field treatment device is capable of generating a control signal for performing electric field treatment on a target tumor location in response to target tumor location information confirmed by a user, that is, the host selects different combinations of electric field output directions according to different locations of a tumor of the user, thereby covering the tumor to the maximum extent and improving a therapeutic effect through multi-directional combinations. The output switch circuit in the electric field output device provided by the embodiment of the disclosure is matched with the output control circuit to realize output on-off of each electrode patch, and the switching sequence can be freely combined.

To facilitate a further understanding of the principles regarding sequential combinations, the above-described illustration of the electric field example in 8 directions may be used.

For example, when the tumor position is located in the left front of the head, the treatment can be performed in the electric field direction shown in fig. 6 (b) and 6 (c) so as to obtain the optimal treatment effect.

In practical application, the host device in the embodiment of the disclosure may further be provided with a relevant tumor position confirmation key, so that the tumor position can be further calibrated under the confirmation of the patient or doctor, and the targeted treatment of the tumor is promoted.
