Technical field

The utility model belongs to headache therapeutic equipment control system technical field, and in particular to a kind of through cranial nerve physiotherapy The control system of instrument.

Background technology

Headache (migraine) is clinical most common primary headaches type, clinical with ictal middle severe, beating sample head Pain is main performance, and headache is mostly inclined side.

The therapeutic purposes of headache (migraine) are to mitigate or terminate Headache attacks, alleviate concomitant symptom, prevent headache recurrence. Treatment means include two aspects of drug therapy and non-drug therapy.Drug therapy is had a headache degree, adjoint by doctor according to patient Symptom, the past medicining condition etc. consider, and determine therapeutic regimen.But it is usually present a degree of pair using drug therapy Effect, patient are likely to occur adverse reaction.

Non-drug therapy is mainly physical therapy, electrotherapy can be used, magnetic therapy, psychological counseling relieve stress etc..With drug Treatment is compared, and maximum advantage is exactly the toxic side effect for being not in drug.

As shown in fig. 6, the treatment pulse that the pulse shaping circuit generates is positive and negative alternately bipolar pulse, with pulse Simple to repeat difference, each period paraphase for the treatment of pulse polarity that this circuit generates is primary, specifically takes the form of, previous Period negative pulse terminates, and latter period negative pulse starts；Previous cycle positive pulse terminates, and latter period positive pulse starts, in this way It can so that therapeutic effect is more preferable.

Master-plan is in line with the theory of " first survey and control afterwards ", and in whole work process after powering, system is dynamically supervised always Survey pulsed electrode, skin and collagen patch electrode electrical characteristics, and according to measurement result optimize treatment parameter, automatically adapt to battery, The characteristic variations of skin and collagen electrode make every effort to every user and are attained by optimum therapeuticing effect.Fully taking into account simultaneously makes The personalized difference of user devises three kinds to the more personalized therapy programs of user on system hardware platform base Operating mode, pulse frequency, pulse width, the pulse strength of Three models are different, are all according to opening however, which kind of pattern Machine afterpulse amplitude gradually increases (being to be automatically increased, grow from weak to strong), keeps stablizing a period of time after reaching design object, this The treatment experience that the treatment mode to grow from weak to strong can allow user to obtain is being improved.Nonetheless, in the arteries and veins of each pattern It rushes during amplitude gradually increases, user can press that singly-bound multiplexing button is primary, and treatment intensity is locked in works as immediately at any time Preceding state, until this treatment cycle terminates.

It cannot recognize being further described made by the present embodiment the above content is specific preferred embodiment is combined The specific implementation for determining the present embodiment is confined to these explanations.The present embodiment person of an ordinary skill in the technical field is come It says, under the premise of not departing from the present embodiment design, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to this The protection domain of embodiment.
