Abstract

This invention proposes a pulsed magnetic shaping instrument and its automatic identification method, system, control method, and circuit. It solves the problems of conventional shaping instruments, such as the inability to control a single channel of magnetic stimulation with a single power supply and the difficulty of channel switching and automatic channel identification. Its main technical solution includes the following steps: the lower magnetic computer first powers on the current coil channel through the main control board, then sequentially enumerates all coil type codes and communicates with the current coil channel. At the same time, it reads the current channel coil value through the Modus protocol. The success of the reading is determined by whether the initial coil address of the type coil is returned. If the reading is successful, the channel identifier in the initial coil address is modified to the current channel identifier to form the channel coil address. The channel coil address is then stored, and the current coil channel is recorded as connected and the current coil is powered off. If the reading fails, it is determined that the current coil channel is not connected to a coil. Finally, the upper magnetic computer reads the stored channel coil address to determine the coil type.

Description

Technical Field

[0001] This invention relates to the field of magnetic shaping instrument technology, and in particular to a pulse magnetic shaping instrument and its automatic identification method, system, control method and circuit. Background Technology

[0002] The application of Transcranial Magnetic Stimulation (TMS) technology has developed rapidly and has been widely used in the fields of mental health and neurorehabilitation. With the deepening exploration and application of magnetic stimulation technology, its application in stimulating the sacral nerve to treat diseases such as urinary incontinence and stimulating the female perineum for postpartum rehabilitation has become a hot application in the field of magnetic stimulation in recent years.

[0003] However, the common magnetic stimulation devices currently available on the market share the following common problems:

[0004] 1) It can only control a single channel of magnetic stimulation with a single power supply, and channel switching is required. It cannot achieve simultaneous magnetic stimulation of two channels.

[0005] 2) The channels cannot be automatically identified, and manual selection of the corresponding insertion port is required for treatment. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a pulse magnetic shaping instrument that can automatically identify coil channels and has multiple channels that can work independently or simultaneously, as well as its automatic identification method, system, control method and circuit.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a pulse magnetic shaping instrument, including: a magnetic upper computer, a magnetic lower computer, several stimulation coils, a liquid-cooled control board and a pressure kit. The magnetic lower computer is used to identify the type of stimulation coil and feed it back to the magnetic upper computer. The magnetic upper computer is used to read the data from the magnetic lower computer, select the corresponding control module to realize the output of the stimulation coil, and control the operation of the pressure kit through the liquid-cooled control board.

[0008] Furthermore, the magnetic host computer model can be upgraded via the cloud and USB flash drive.

[0009] The automatic identification method of the pulse magnetic shaping instrument includes the following steps:

[0010] S1. The lower-level magnetic controller first powers on the current stimulation coil channel via the main control board, then sequentially enumerates all stimulation coil type codes and communicates with the current stimulation coil channel. Simultaneously, it reads the stimulation coil value of the current channel via the Modus protocol. The success of the read is determined by whether the initial stimulation coil address of the corresponding type of stimulation coil is returned.

[0011] Upon successful reading, the channel identifier in the initial stimulation coil address is modified to the current channel identifier, forming the current channel stimulation coil address. This current channel stimulation coil address is then stored. Simultaneously, the current coil channel is recorded as connected, and the current coil is de-energized.

[0012] If a read fails, it is determined that no coil is connected to the current coil channel;

[0013] S2. The magnetic lower-level machine repeats the S1 operation on all stimulation coil channels in sequence until all stimulation coil channels are identified.

[0014] S3. The magnetic host computer reads all channel stimulation coil addresses stored in the magnetic slave computer via RS485 line, compares the stimulation coil type code in each channel stimulation coil address with the predetermined coil type code to identify the stimulation coil type, and controls the stimulation coil of the corresponding channel to be powered on according to the channel identifier in each channel stimulation coil address.

[0015] Furthermore, both the initial stimulation coil address and the channel stimulation coil address include a channel identifier and a stimulation coil type code, and each stimulation coil channel has a definite and unique channel identifier.

[0016] Furthermore, the stimulation coil type is coded as addr(n), where n takes values ​​from 1 to 11, namely, large circle T-shaped coil, pelvic floor liquid cooling, pelvic floor air cooling, external figure-eight T-shaped coil, cone T-shaped coil, helmet butterfly coil, elliptical coil, small butterfly coil for children, small circle coil for children, buttock shaping coil and abdominal shaping coil.

[0017] Furthermore, the stimulation coil has two independent channels.

[0018] Furthermore, the magnetic host computer maintains communication with the stimulation coil during operation. If the magnetic host computer fails to respond to repeated stimulation coil communications, it stops working.

[0019] The pulse magnetic body shaping system includes: an abdominal module, a buttocks module, a custom module, a treatment record module, and a system setting module. The custom module includes a two-channel treatment mode for the buttocks and abdomen, a two-channel treatment mode for the abdomen, and a two-channel treatment mode for the buttocks. The treatment record module is used to record the treatment site, time, and intensity. The system setting module is used to set the initial parameters of the system.

[0020] The control method for the pulse magnetic shaping instrument system is characterized by the following steps:

[0021] When a stimulation coil for the buttocks or abdomen is inserted, the magnetic host computer selects and controls the corresponding control module, namely the buttocks or abdomen module, and the buttocks and abdomen modules respectively enter the single-channel treatment interface.

[0022] When both the buttock stimulation coil and the abdominal stimulation coil are inserted simultaneously, the magnetic host computer selects and controls the custom module, which means entering the two-channel interface for the buttock and abdomen.

[0023] When two abdominal stimulation coils are inserted, the magnetic host computer selects and controls the corresponding abdominal or custom module (the buttock module turns gray). The abdominal module enters the treatment interface for the two abdominal channels, and the custom module enters the treatment interface for the two abdominal channels.

[0024] When two buttock stimulation coils are inserted, the magnetic lower unit identifies the type of stimulation coil. The location module displays the buttocks and the custom module (the abdomen module turns gray). The buttocks module enters the two-buttock channel treatment interface, and the custom module enters the custom two-buttock channel treatment interface.

[0025] The abdominal module determination steps are as follows: first, determine whether dual channels are selected on the abdominal page; then, detect the pressure kit and determine whether to display the pressure muscle detection waveform; then, click "Start Treatment" and determine whether to issue a treatment plan, adjust the intensity and display the corresponding waveform; finally, end the treatment and save the record.

[0026] The buttock module determination steps are as follows: first, determine whether dual channels are selected on the buttock page; then, click "Start Treatment" and determine whether to issue a treatment plan and adjust the intensity; finally, end the treatment and save the record.

[0027] The custom module determination steps are as follows: first, detect the channel stimulation coil type and select whether to use dual channels in the custom interface; then, edit the custom plan according to the stimulation coil type; then, click "Start Treatment" and determine whether to issue the plan and adjust the intensity; finally, end the treatment and save the record.

[0028] The circuit structure of the pulse magnetic shaping instrument is a single power supply structure, which includes a high voltage power supply, a pulse capacitor and at least two stimulation coils. The high voltage power supply is electrically connected to the pulse capacitor, and multiple stimulation coils are connected in parallel with the high voltage power supply. Each stimulation coil is charged through a thyristor and discharged through a thyristor.

[0029] Compared with the prior art, the beneficial effects of the present invention include:

[0030] 1. It adopts a single power supply to achieve independent dual-channel treatment, which can be either single-channel or dual-channel, to meet the needs of all treatment scenarios;

[0031] 2. Each channel can adapt to different coils, so as to first automatically identify the type of stimulation coil to provide a feasible treatment module, and then determine the number of channels to achieve treatment;

[0032] 3. Use a seven-layer architecture with strict layering. Each layer should only do what it is supposed to do to avoid high coupling and large modules. The presentation layer should not contain business logic and should only handle presentation logic. The business layer should handle all business logic and should not contain database access logic. Each module should have a single responsibility, be small rather than large, maximize module reuse, avoid duplicate code, and each module should only expose necessary interfaces that are easy to test.

[0041] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0042] According to one embodiment of the present invention, Figures 1-6 As shown.

[0043] Regarding the overall structure of the magnetic shaping instrument in this embodiment, as follows: Figure 1As shown, it mainly includes a magnetic host computer, a magnetic slave computer, several stimulation coils, a liquid-cooled control board, and a pressure kit. In use, the magnetic slave computer identifies the type of stimulation coil by identifying the pre-coded and classified stimulation coils and feeds it back to the magnetic host computer. The magnetic host computer then reads the data from the magnetic slave computer and selects the corresponding control module for different stimulation coil types. The control module then controls the pressure kit, i.e., the airbag, to work through the liquid-cooled control board. The magnetic host computer itself can also be upgraded via cloud disk and USB flash drive to meet the actual iteration and upgrade of the product.

[0044] Specifically, the method for the magnetic lower-level machine to identify the stimulation coil is as follows:

[0045] S1. The lower-level magnetic controller first powers on the current stimulation coil channel via the main control board, then sequentially enumerates all stimulation coil type codes and communicates with the current stimulation coil channel. Simultaneously, it reads the stimulation coil value of the current channel via the Modus protocol. The success of the read is determined by whether the initial stimulation coil address of the corresponding type of stimulation coil is returned.

[0046] Upon successful reading, the channel identifier in the initial stimulation coil address is modified to the current channel identifier, forming the current channel stimulation coil address. This current channel stimulation coil address is then stored. Simultaneously, the current coil channel is recorded as connected, and the current coil is de-energized.

[0047] If a read fails, it is determined that no coil is connected to the current coil channel;

[0048] S2. The magnetic lower-level machine repeats the S1 operation on all stimulation coil channels in sequence until all stimulation coil channels are identified.

[0049] S3. The magnetic host computer reads all channel stimulation coil addresses stored in the magnetic slave computer via RS485 line, compares the stimulation coil type code in each channel stimulation coil address with the predetermined coil type code to identify the stimulation coil type, and controls the stimulation coil of the corresponding channel to be powered on according to the channel identifier in each channel stimulation coil address.

[0050] Both the initial stimulation coil address and the channel stimulation coil address include a channel identifier and a stimulation coil type code. Each stimulation coil channel has a unique channel identifier. For the stimulation coil type code in S1, different types of stimulation coils correspond to different RS485 communication addresses. Specifically, the coil type code is marked as addr(n), where n takes values ​​from 1 to 11 (in practice, n can be extended to 1 to 31, meaning that based on 1 to 11, 12 to 31 can match stimulation coils with more functional types), as follows:

[0051]

[0052]

[0053] The formation and storage of the channel coil addresses in S1 are shown in the table below.

[0054]

[0055] The connection between the stimulation coil and the host is via an RS485 bus. The stimulation coil, acting as a slave, communicates with the programmable control board in the host via the RS485 bus. Simultaneously, the high-voltage power supply module also acts as a slave and connects to the programmable control board via the same RS485 bus. This bus communication uses the Modbus protocol, so each slave has a unique one-byte address ID. For the stimulation coil, the stimulation coil type code is used as the address ID for communication. Since multi-channel devices may have multiple stimulation coils and multiple power supplies, the same stimulation coil type may appear when multiple stimulation coils are present. To avoid address ID conflicts, a channel identifier is introduced to distinguish the stimulation coil when establishing a connection. As shown in the table above, bits 0-4 represent the stimulation coil type (range 1-31), bit 5 indicates the slave type (0 for a coil, 1 for a power supply), and bits 6-7 indicate the channel the stimulation coil belongs to. When connecting the stimulation coil, the channels should be powered on and queried in descending order of channel number. When the stimulation coil type is found, the updated address ID with the corresponding channel identifier (i.e., the channel stimulation coil address) should be written to the stimulation coil and then stored in the magnetic lower-level machine.

[0056] Specifically, in this embodiment, taking a dual-coil channel and an abdominal / buttock stimulation coil as an example, the corresponding control system includes an abdominal module, a buttock module, a custom module, a treatment record module, and a system setting module.

[0057] like Figure 2 As shown, for the system as a whole, after logging in through the login interface on the main screen, the magnetic host computer can independently select different modes, including abdominal mode, hip mode and custom mode. All three modes are controlled by a single power supply and dual channels, and the temperature can be monitored by the temperature monitoring module during operation. In abdominal mode, the user's abdominal muscles can also be monitored by the muscle status monitoring module.

[0058] In custom mode, since the two channels are independent of each other, there are three states: two-channel treatment mode for buttocks and abdomen, two-channel treatment mode for abdomen, and two-channel treatment mode for buttocks. The channel parameters of each mode can be adjusted through the program parameter adjustment module.

[0059] Similarly, the system also includes a treatment record module and a system settings module. The treatment record module mainly includes the treatment site, treatment time, treatment intensity, and the generated report for each treatment, which is convenient for different users to manage. The system settings module is for adjusting the parameters of the whole machine, such as language selection, volume adjustment, brightness adjustment, system time, login interface management, and basic host parameters such as screen height adjustment, stimulation coil type, and overall muscle condition assessment.

[0060] When a stimulation coil for the buttocks or abdomen is inserted, the magnetic host computer selects and controls the corresponding control module, namely the buttocks or abdomen module, and the buttocks and abdomen modules respectively enter the single-channel treatment interface.

[0061] When both the buttock stimulation coil and the abdominal stimulation coil are inserted simultaneously, the magnetic host computer selects and controls the custom module, which means entering the two-channel interface for the buttock and abdomen.

[0062] When two abdominal stimulation coils are inserted, the magnetic host computer selects and controls the corresponding abdominal or custom module (the buttock module turns gray). The abdominal module enters the treatment interface for the two abdominal channels, and the custom module enters the treatment interface for the two abdominal channels.

[0063] When two buttock stimulation coils are inserted, the magnetic lower unit identifies the type of stimulation coil. The location module displays the buttocks and the custom module (the abdomen module turns gray). The buttocks module enters the two-buttock channel treatment interface, and the custom module enters the custom two-buttock channel treatment interface.

[0064] like Figure 3 As shown, for the overall process of the abdominal module, firstly, the magnetic host computer interface selects whether to use dual channels, then selects whether to use the pressure detection kit to detect the user's abdominal muscles and present the waveform, then the treatment begins, after the treatment, the user can choose whether to issue a plan, adjust the intensity, display the corresponding muscle waveform, and monitor and report abnormalities, and finally end the treatment and save the treatment record.

[0065] like Figure 4 As shown, for the overall process of the buttock module, firstly, the buttock page determines whether to select dual channels, then click "Start Treatment" and determine whether to issue a treatment plan and adjust the intensity, and finally end the treatment and save the record.

[0066] like Figure 5 As shown, for the overall process of the custom module, firstly, the channel stimulation coil type is detected and dual-channel is selected in the custom interface. Then, the custom plan is edited according to the stimulation coil type. Next, the start treatment is clicked and it is determined whether to issue the plan and adjust the intensity. Finally, the treatment is ended and the record is saved.

[0067] Regarding the circuit structure in this embodiment, such as Figure 6 As shown, the circuit structure adopts a single power supply structure, which includes a high-voltage power supply, a pulse capacitor and at least two stimulation coils. The high-voltage power supply and the pulse capacitor are electrically connected, and multiple stimulation coils are connected in parallel with the high-voltage power supply. Each stimulation coil is charged through a thyristor and discharged through a thyristor.

[0068] like Figure 6 As shown, taking the power supply structure of dual-channel coil stimulation as an example, stimulation coil L1 and stimulation coil L2 are connected in parallel with the high-voltage power supply. Stimulation coil L1 is charged and discharged through thyristors Q1 and Q2, and stimulation coil L2 is charged and discharged through thyristors Q3 and Q4. When Q1 is on, L1 is charged; when Q1 is off and Q2 is on, L1 is discharged, and the same applies to L2.

[0069] like Figure 7 As shown, taking the power supply structure of a four-channel coil stimulation as an example, the stimulation coils L3 and L4 are the same as L1 and L2 in the dual-channel system. The four stimulation coils are also connected in parallel with the high-voltage power supply. Stimulation coil L3 achieves the charging and discharging of the coil in the channel through thyristors Q5 and Q6, respectively. Stimulation coil L4 achieves the charging and discharging of the coil in the channel through thyristors Q7 and Q8, respectively. When Q5 is on, coil L3 is charged; when Q5 is off, coil L3 begins to discharge, and the same applies to L4.

[0070] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
