Description

Technical Field

[0001] The utility model relates to the technical field of medical care equipment, in particular to a pulse circuit system with self-programmable graphics and adjustable intensity and an electrotherapy device thereof. Background Art

[0002] The electrotherapy device uses alternating current or pulsed electricity of a certain voltage and frequency, which is connected to the human body through electrodes. The current stimulates the acupuncture points of the human body for treatment and rehabilitation. Since many components of human tissue have certain electrical properties, when the pulse current passes through the affected part of the human body, the muscles, nerves, body fluids, and blood of the human body will produce a certain degree of physical and chemical reaction. The scope of application of the electrotherapy device: used for analgesia; improving local blood circulation, promoting the dissipation of inflammation; softening scars, loosening adhesions and other therapeutic effects, without any toxic side effects. The electronic therapy device is suitable for any health care, health care, beauty, rehabilitation, physical therapy institutions, etc. Its characteristics of not requiring injections or medication avoid iatrogenic and drug-induced infections. Many people feel that it is safer, so the demand for electronic therapy devices is constantly increasing.

[0003] Electrotherapy devices are being used by more and more people, but the corresponding physical sensations have attracted much attention. Only rich physical sensations can reduce waveform tolerance when people use electrotherapy devices and obtain more effective usage experience and treatment.

[0004] The pulse circuits of existing electrotherapy devices no longer meet the requirements for a rich user experience. This is because the waveforms they output are relatively simple, resulting in poor user experience. The increase and decrease in waveform output intensity are not subtle enough, which can cause intolerance in sensitive people. Furthermore, massage techniques used by medical staff or technicians include but are not limited to tapping, pressing, kneading, pinching, and combinations of these techniques, as well as the most appropriate pressure technique and frequency for the corresponding condition. Existing electrotherapy devices cannot simulate massage techniques.

[0005] In view of this, how to solve the above problems existing in the prior art has become the subject to be studied and solved by this utility model. Utility Model Content

[0007] 1. How to achieve the output of pulse waveforms of different shapes.

[0008] 2. How to increase or decrease the intensity of the pulse output.

[0009] 3. In addition to self-programming to output different waveforms, how to realize the function of autonomously learning the massage waveforms of medical staff or technicians and storing the records for waveform reproduction output or research.

[0010] To achieve the above-mentioned purpose, the first aspect of the present invention proposes a pulse circuit system with self-programmable graphics and adjustable intensity, wherein the pulse circuit system includes a main control chip module connected by wires, a modulation waveform output module, a modulation waveform intensity control module, and a modulation waveform secondary amplification module.

The power amplifier chip has a modulation waveform input pin, which is electrically connected to the modulation waveform output pin. The modulation waveform input pin is connected to the power amplifier chip, the transformer, and the electrode sheet in sequence.

[0016] 1. In the above technical solution of the present invention, the output of different-shaped pulse waveforms and the increase or decrease of pulse intensity at the same time as pulse output are achieved through the innovative design of the main control chip module, the modulation waveform output module, the modulation waveform intensity control module, and the modulation waveform secondary amplification module in the above pulse circuit system. To achieve the output of different-shaped pulse waveforms, when the user uses it, the PWM output function of the main control chip is used to output a PWM wave with a set frequency, and the PWM wave is introduced into the first voltage reference pin of the first modulation chip as the voltage reference value of the waveform output (the reference is the maximum voltage value that can be output). At the same time, the first data input receiving pin receives the control of the main control chip, which enables the first modulation chip to set different voltage output ratios according to the DATA value, thereby outputting different amplitude voltage values, so as to depict the modulation, etc. The output waveform is amplified by an op amp for use in subsequent circuits. To achieve simultaneous pulse output and intensity sensory increase and decrease, the amplified modulated waveform is introduced into the second voltage reference pin of the second modulation chip as the voltage reference value for the waveform output (this reference is the maximum output voltage value). Simultaneously, the second data input receiving pin receives control from the main control chip, enabling the second modulation chip to set different voltage output ratios according to the DATA value, thereby outputting different amplitude voltage values.

The multi-channel chip collector has a press data sending pin, and the main control chip is provided with a press data receiving pin electrically connected to the press data sending pin. Using a matching manikin covered in pressure sensors, a medical professional or technician massages the corresponding areas. The voltage output of the pressure sensors in the corresponding areas changes with the pressure applied. This voltage is then amplified by a third op amp and fed into a multi-channel chip data collector. The main control chip reads the ADC chip and the corresponding area channels to convert the analog voltage into a digital value and associate it with the relevant area. The main control chip then transmits the collected digital values ​​and area to a host computer via a communication interface. The host computer visually depicts the pressure waveform based on the digital values ​​and records and saves the generated waveform array and the corresponding massage area, thereby learning the massage technique waveform of the medical professional or technician. If there are any related symptoms, the operator can also enter this information into the host computer and archive it.

For the realization of self-learning, please refer to the following.

[0077] The process of achieving self-learning:

[0078] To achieve the self-learning process, a matching dummy with pressure sensors 51 all over its body is used. After the medical staff or technicians massage the corresponding parts of the body, the voltage output value of the pressure sensor 51 at the corresponding part will change with the change of the pressure. After being amplified by the third operational amplifier component 52, it is sent to the multi-channel chip collector 53 (the accuracy of the ADC chip is 24 bits, and the output digital value range is 0~2^ 24 )), the main control chip 13 converts the voltage analog quantity into an intuitive digital quantity and matches the value with the relevant part by reading the ADC chip and the relevant part channel of the ADC chip. At the same time, the main control chip 13 uploads the real-time collected digital quantity value and part to the host computer 11 through the communication interface. The host computer 11 intuitively depicts the waveform style of the pressing pattern based on the digital quantity value, and records and saves the array of generated relevant waveforms and the corresponding massage parts, thereby learning the massage technique waveform of the medical staff or technician. If there are related symptoms, the operator can input them into the host computer 11 and archive them. In this way, the detailed record of the massage technique of the medical staff or technician can be learned by self-learning, enriching the waveform body sensory library while facilitating later research and waveform reproduction.

[0079] The massage techniques that can be learned include but are not limited to tapping, pressing, kneading, pinching, etc., as well as the combination of various techniques, and the most suitable pressing techniques and pressing frequencies for the corresponding symptoms, which are convenient for research and use or for calling waveforms to reproduce and output massage. The waveforms corresponding to some massage techniques can be referred to 9A to 9D shown.

[0080] In the later stage, the main control chip 13 can cooperate with the modulation waveform output module 2 and the modulation waveform intensity control module 3 according to the array data generated by the host computer 11 to reproduce the massage technique in a 1:1 manner and at the same time can also amplify or reduce the massage intensity as a whole, which is more convenient.

[0081] The learned data can be later organized into relevant disease prescriptions. Different waveform techniques and different frequency combinations can be output directly through the disease configuration input of the host computer 11, and sent to the main control chip 13 for execution. Common disease prescription configurations can also be stored in the memory chip 12 or the flash memory inside the main control chip 13, and the main control chip 13 can directly call them offline.
