TENS) based on device, pulse is generated on the skin using electric current, to change brain to the consciousness of pain, can be used to mitigate joint
Scorching or chronic disease pain.
However, previous nerve stimulator exports stimulated current in a manner of high-voltage pulse, general is mostly in stimulator
A variable resistance is arranged in output end, and changes the size of output electric current by the resistance value of user's adjustment control variable resistance,
But under different human body impedance factors, stimulus intensity is not only not easy to be controlled by user, but also provided by input source
Driving voltage can't by variable resistance adjustment and change, therefore cause the empty consumption of driving voltage.
Another aspect, electrotherapy patch belong to consumables, when access times increase or save with use it is improper, all it is possible that
The consume of patch is caused, most obvious one symptom can exactly be fallen in use.However this be to user it is breakneck,
Because the area that patch when sliding, contacts skin changes, it is likely to result in the unstable of stimulated current output；And work as patch
When pasting back once again, user may not feel good to precipitate pulse.
And previous user is that can experience obvious electrotherapeutic effect, the most common mode is exactly mentioning nerve stimulator
High-output power, however, will lead to output power can also go out when input voltage occurs exception suddenly or even surge signal occurs
Now abnormal, user can not feel well when in use, and the output of voltage persistent anomaly also be easy to cause power wastage, if it is
When using battery as power supply, the electric power of battery will be rapidly depleted.
Therefore, how a kind of empty consumption can effectively reduce driving voltage is provided, and improves electrotherapy and contacts skin with patch
When there is unstable stimulated current to be directly delivered to human body, and how to avoid input voltage extremely and lead to user's body
Discomfort, while electricity exception void how can also be avoided to consume, these all can be this case the problem of being focused on and focus.
