The preset program parameter information can be stimulation intensity parameter information, which is set by a user (including but not limited to a patient, a family member, and a medical staff), including but not limited to stimulation amplitude, frequency, pulse width, period, etc.

[0047] The controller module 20 can be electrically connected with the stimulation module 30, and the controller module 20 can be configured to obtain the preset stimulation program by looking up a table according to the preset program parameter information received from the program module 40. Further, the controller module 20 can generate a power control signal and a stimulation program signal corresponding to the obtained preset stimulation program, and can transmit the generated stimulation program signal to the stimulation module 30 and the generated power control signal to the power module 10, so that the power module 10 can output the required stimulation voltage to the stimulation module 30, thereby enabling the stimulation module 30 to output the required stimulation waveform to the patient.

[0048] The controller module 20 can include a processor or a microprocessor (MCU), etc. Optionally, the controller module 20 can further include a memory. The memory stores a mapping table of the preset program parameter information and the preset stimulation program. In addition, the above-mentioned operations / functions of the controller module 20 can be implemented as computer readable codes / algorithms / software stored on the memory thereof, which can include a non-volatile computer readable recording medium. The non-volatile computer readable recording medium is any data storage device that can store data readable by a processor or a microprocessor. Examples of the computer readable recording medium include a hard disk drive (HDD), a solid state drive (SSD), a silicon disk drive (SDD), a read-only memory (ROM), a random access memory (RAM), a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, etc. The processor or the microprocessor can perform the operations / functions of the controller module 20 by executing the computer readable codes / algorithms / software stored on the non-volatile computer readable recording medium. Specifically, the second stage boost circuit 13 of the power module 10 can be electrically connected with the controller module 20, and the second stage boost circuit 13 can be configured to adjust the second level outputted by the second stage boost circuit 13 to the stimulation module 30 according to the power control signal of the controller module 20 received from the controller module 20.

[0049] In the exemplary embodiment of the present application, the controller module 20 can control the output of the second-stage boost circuit 13, specifically, the controller module 20 can compare the actual output voltage of the second-stage boost circuit 13 with the stimulation voltage required by the stimulation module 30 obtained according to the received preset programmed parameter information, and can adjust the actual output voltage of the second-stage boost circuit 13 so that the actual output voltage of the second-stage boost circuit 13 is equal to the stimulation voltage required by the stimulation module 30 obtained according to the received preset programmed parameter information, thereby providing the stimulation module 30 with the required stimulation voltage to achieve the best working effect.

[0050] The stimulation module 30 can be configured to receive a stimulation program signal from the controller module 20 and generate stimulation waveforms of multiple channels according to the received stimulation program signal. In the embodiment according to the present application, the stimulation program signal can include but is not limited to stimulation amplitude, frequency, pulse width, period, etc. parameter information.

The stimulation module 30 can output a wider range of stimulation current, such as 0.2mA-20mA stimulation current, according to the stimulation voltage output from the power supply module 10.

[0051] Therefore, the multi-channel extracorporeal stimulator according to the exemplary embodiment of the present application can support more stimulation channels, more stimulation modes and a wider range of stimulation current amplitudes, so that the doctor can set multiple treatment programs for the patient's condition to achieve the best treatment effect.

[0052] In addition, in order to improve the safety and reliability of the power supply module 10, the power supply module 10 can further include a monitoring circuit 14. Referring to Figure 2 , the monitoring circuit 14 can be electrically connected with the battery 11 and the controller module 20 respectively, and the monitoring circuit 14 can be configured to monitor the voltage of the battery 11 and send the monitoring result to the controller module 20. The controller module 20 can compare the received voltage of the battery 11 with a preset voltage, and when the difference between the voltage of the battery 11 and the preset voltage exceeds a threshold value, send a signal of abnormal battery voltage to the input and output module 50 and / or the programmed module 40, so that the user can replace the battery 11 of the power supply module 10 in time.

[0053] Further, the controller module 20 can be configured to periodically activate the monitoring circuit 14 to reduce the power consumption of the multi-channel external stimulator. According to an embodiment of the present application, the controller module 20 can be further configured to deactivate the second-stage boost circuit 13 when the stimulation module 30 is not activated or in a standby mode (which can be a power-on only mode, but the controller module 20 has not yet received the preset programming parameter information sent by the programming module 40 and the pressing instructions of the input and output module 50), so that the multi-channel external stimulator of the embodiment of the present application can be more energy-saving and thus can be used for a longer time.

[0054] Referring back to Figure 1 , the multi-channel external stimulator according to an exemplary embodiment of the present application can further include an input and output module 50, which can be electrically connected to the controller module 20.

[0057] Specifically, in an exemplary embodiment of the present application, the key unit 52 can include m stimulation program keys, where m is a positive integer greater than or equal to 1.

In addition, the key unit 52 can include a "+" key for increasing the stimulation intensity and a "-" key for decreasing the stimulation intensity. For each preset stimulation program, the user can increase or decrease the stimulation intensity through different keys of the key unit 52 to achieve the stimulation intensity required by the patient, so as to obtain the best therapeutic effect.

[0058] In addition, the pressing instruction can further include a third instruction of stopping the external stimulation in time, and correspondingly, the key unit 52 can further include a "stop" key. In the case of abnormal battery voltage of the battery 11 of the power module 10 and working information of the multi-channel external stimulator, the user can stop the working of the multi-channel external stimulator in time through the "stop" key on the input and output module 50. In the case that the patient feels uncomfortable, the patient can also stop the working of the multi-channel external stimulator in time through the "stop" key, so that the multi-channel external stimulator according to the exemplary embodiment of the present application will not cause harm to the human body.

[0059] The stimulation module 30 can further include a detection unit. The detection unit can be configured to detect stimulation state information of the stimulation site of the patient in real time, including but not limited to electrode connection state, current, temperature and other stimulation state information, and send the detected stimulation state information to the controller module 20.

[0060] The controller module 20 can be further configured to issue an alarm through the input and output module when it is determined that the stimulation state information is abnormal. Specifically, the input and output module 50 can further include a first alarm unit. When the controller module 20 determines that the stimulation state information is abnormal, the controller module 20 can send a signal of abnormal stimulation state information to the first alarm unit to make the first alarm unit issue an alarm and display the abnormal stimulation state information on the display unit 51, so that the user can know the abnormal stimulation state information in time and stop the working of the multi-channel external stimulator in time, so that the multi-channel external stimulator according to the exemplary embodiment of the present application will not cause harm to the human body.

[0061] In order to enable medical staff to know whether the stimulation state information of the multi-channel external stimulator used by the patient is abnormal or an emergency occurs in time, the program control module 40 can further include a second alarm unit. When the controller module 20 determines that the stimulation state information is abnormal, the controller module 20 can send a signal of abnormal stimulation state information to the second alarm unit to make the second alarm unit issue an alarm, so that the medical staff can stop the working of the multi-channel external stimulator in time, so that the multi-channel external stimulator according to the exemplary embodiment of the present application will not cause harm to the human body.

[0062] In an emergency, for example, in the case of an emergency such as electrode connection abnormality, overcurrent or overtemperature, the controller module 20 can send an emergency stop signal to the second alarm unit to make the second alarm unit issue an alarm of emergency stop, so that the medical staff can stop the working of the multi-channel external stimulator in time, so that the multi-channel external stimulator according to the exemplary embodiment of the present application will not cause harm to the human body.

[0063] The multi-channel external stimulator according to the exemplary embodiments of the present application can realize more stimulation modes and wider stimulation current amplitudes by supporting more stimulation channels, so that a doctor can set multiple treatment programs for a patient's condition to achieve the best treatment effect.

[0064] In addition, the multi-channel external stimulator according to the exemplary embodiments of the present application can be more energy-saving by periodically operating the monitoring circuit 14 of the power module 10 and / or controlling the enable / disable of the second-stage boost circuit 13, so that the multi-channel external stimulator according to the embodiments of the present application can support a longer use time.
