Embodiment 1

[0030] A wearable transcutaneous electrical nerve stimulation treatment device for dysmenorrhea, including: a power supply module, a control module, a waveform modulation module, an electrode sheet connected to the human body, and a mobile terminal APP;

[0031] The waveform modulation module includes a waveform generating circuit and a power amplifier circuit;

[0032] The power amplifying circuit is composed of a class D power amplifier and an intermediate frequency transformer, the class D power amplifier amplifies the waveform output by the waveform generating circuit, and the class D power amplifier uses a 12V power supply voltage to improve The output voltage of the output voltage; the intermediate frequency transformer further boosts the output voltage of the class D power amplifier, and the intermediate frequency transformer adopts the EPC direct plug-in skeleton.

[0033] Specifically, to meet the conditions of low power consumption, high efficiency and high output vo...

Embodiment 2

[0043] There are two common design schemes for existing transcutaneous electrical nerve stimulation treatment equipment for dysmenorrhea. One is to generate low-frequency high-voltage signals through RLC resonance, and then output pulse signals through triode chopping. The pulse waveform output by this scheme is a single rectangular wave, which is easy develop drug resistance. The other is to directly use the DAC to directly generate the small signal form of the target waveform, and then amplify the power to output the stimulation waveform. However, since the transformer is used in the power amplifier device, and the stimulation signal is a medium-low frequency signal, the volume of the medium-low frequency transformer limits the reduction of the total volume of the equipment, which is an obstacle to the portability of the equipment. However, the waveform generated by the DAC in Scheme 2 can flexibly change the waveform form, frequency, amplitude and combination form, etc., wh...

Abstract

The invention discloses a wearable transcutaneous electrical nerve stimulation (TENS) dysmenorrhea therapeutic instrument comprising: a power module, a control module, a waveform modulation module, anelectrode piece connected to a human body and a mobile terminal APP. The power module supplies power to each module of the system. The control module determines a therapeutic prescription by interacting with the mobile terminal APP, and controls the waveform modulation module to generate a stimulation pulse which acts on the human body through the electrode module connected to the human body. Thepower module includes a boosting circuit and a voltage stabilizing circuit. The control module includes a wireless communication circuit and a main control SCM. The waveform modulation module includes a power amplification circuit and a waveform generation circuit. The wearable TENS therapeutic instrument can generate a plurality of prescription waveforms, has high waveform generation efficiencyand accurate waveforms, has an intensity adjustment function, achieves a good therapeutic effect in combination with various current therapies, has a wearable design and a user-friendly interface, andis very easy to operate.

Description

technical field [0001] The invention relates to technical fields such as transcutaneous electrical nerve stimulation analgesic therapy, software and hardware development, the Internet of Things, and in particular to a wearable transcutaneous electrical nerve stimulation treatment instrument for dysmenorrhea. Background technique [0002] Transcutaneous electrical nerve stimulation (TENS for short) is an electrotherapy method that injects specific pulse currents into the human body through the skin to treat pain. In 2001, Clinical Electrophysiology and the American Physiotherapy Association defined Transcutaneous Electrical Nerve Stimulation (TENS) as follows: Transcutaneous Electrical Nerve Stimulation (TENS) is a method of applying electrical stimulation to the skin to control pain. Compared with traditional electrical stimulation, which mainly stimulates the body's motor fibers to achieve analgesic effects, transcutaneous electrical nerve stimulation (TENS) mainly stimulat...
