Description
Technical field
The invention belongs to headache therapeutic equipment control system technical fields, and in particular to a kind of transcutaneous electrical stimulation physical header
The control system of pain therapeutic equipment.
Background technique
Headache (migraine) is the 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, prevention 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. comprehensively consider, and determine therapeutic regimen.But a degree of pair is usually present 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.
In terms of electrotherapy, electrode usually is placed at the certain positions of body surface, applies electric signal.The electrode that body surface is placed
Generally all far from chest, and apply voltage, electric current all very littles, any influence will not be generated to heart.Electrotherapy mainly has directly
Voltaism, galvanoiontophoresis therapy, low frequency impulse current therapy, medium-frequency pulse diathermy, high frequency electrotherapy, electrostatic
Therapy.
Different type electrotherapy is different to the physiological action of human body.What galvanism applied is constant current signal, can also
As medicine-inductiveness；Low, medium-frequency pulse electric current stimulation nerve causes contraction of muscle, is usually used in controlling for neuromuscular disease
It treats, such as non-open injury and chronic ache；High-frequency current promotes local circulation, resolution to the fuel factor of human body with it
And oedema；Static current therapy mainly treats function in local organization using electrostatic field to realize by adjusting nerve.

1. stimulating neuromuscular, cause contraction of muscle, contraction of muscle can promote artery blood supply, vein and lymphatic return, change
Kind part Nutrition and Metabolism, recession oedema also can be improved muscle tone, prevent or delay muscular atrophy process；Stimulate mind to the rhythm and pace of moving things
Through muscle, muscle Rythmic contractions characteristic can be made, to prevent as caused by damage or inflammation between muscle fibre and sarolemma, between muscle bundle
Adhesion, keep the elasticity of muscle, prevent contracture.
2. for relieving pain：It is main that the low-frequency pulse of the current strength beyond general dosage (is used using ultrastimulating electrotherapy
Therapy) and transcutaneous electric nerve stimu lation (TENS).There are two types of may for low-frequency electric pulse analgesia mechanisms.First, low-frequency pulse
Stream has restrained pain nerve and has transmitted impulsion to maincenter；Second, low-frequency pulse promotes local blood circulation, dissipate local induced pain
Substance improves tissue metabolism's function, thus plays analgesic effect.
But there is many defects for existing electric pulse headache therapeutic equipment, the frequency of electric pulse is single, selective frequency

That is, the amplitude of output treatment pulse is bigger, the high pressure that booster circuit provides is higher, and the amplitude of output treatment pulse is got over
Small, the voltage that booster circuit provides gets over low pressure.Otherwise, if no matter output treatment impulse amplitude size, using simple constant height
Power voltage supply, when necessarily causing output treatment impulse amplitude smaller, internal circuit pressure drop is excessive, and circuit energy consumption increases.
Control for pulse shaping circuit, since the pulses range of circuit output is 60-120Hz, pulse width
It is 250-300 μ s, that is to say, that within the most short about 8ms period, at most only there is pulse output in the 0.6ms time, remaining

The voltage boosting pulse signal that microcontroller provides, motivates DC-DC booster circuit, and cell voltage boosting becomes a higher direct current
Voltage VH directly powers for pulse signal generative circuit.Pulse signal generative circuit exports pulse by the control of microcontroller
Signal directly acts on human body finally by collagen patch electrode.
The mode that powers on of the system is started using artificial key, makes LDO power supply chip TPS73101DBVT output 2.4V electricity
Pressure, this voltage makes microcontroller immediately enter working condition, and the corresponding control signal function of output makes in LDO power supply chip
Energy end, takes over the voltage output control to LDO power supply chip, and after key unclamps, then persistently output is effective for microcontroller
Signal keeps the normal work of LDO power supply chip.Through actual test, TPS73101 power supply chip after manual key is pressed,
The voltage output of 2.4V is able to maintain 100ms or more, and time of the Core Microcontroller MSP430 from suspend mode to wake-up is much smaller than
