Description
Technical field
The present invention relates to the technology of a kind of medical instruments field, specifically one Portable percutaneous nerve electric stimulation system
System and method thereof.
Background technology
The research about electricity irritation prevention of deep vein thrombosis abroad starts to walk relatively early, but is also the most just to have more sending out
Exhibition, mainly includes that electricity irritation lower limb different parts affects in short-term and for a long time on deep veins of lower limb is hemodynamic, and with
The effectiveness comparison etc. of other several physical prophylaxis modes.The mode of electricity irritation mainly includes neuromuscular electric stimulation therapy
(Neuromuscular electrical stimulation) and transcutaneous electric nerve stimulation (Transcutaneous
Electrical nerve stimulation), the former utilizes electric current to come the motor point of stimulation target muscle or muscle group, thus draws
Playing this muscle or contract muscular group, which is mainly used in delaying or stoping muscle disuse atrophy, neuromuscular function to rebuild, protect
Hold or increase musculation degree, improve the aspects such as muscle spasticity；The latter more emphasizes low-frequency electrostimulating signal work in the past
For sensory nerve, for treatment and the alleviation of pain, its research and clinical practice were beyond pain therapy scope in recent years.
The realization of both stimulation modes is required to the muscular tissue of complete peripheral neuropathy and health.Relative to neuromuscular
Electricity irritation, transcutaneous electric nerve stimulation has several more significantly advantage.First, the pain of transcutaneous electric nerve stimulation is relatively low,
I.e. there is preferably comfort level；Second, need more time to find appropriate muscular movement relative to neuromuscular electric stimulation therapy
Point, transcutaneous electric nerve stimulation is easier to find electricity irritation site；3rd, for common peroneal nerve, its position more table is shallow, Er Qietong
Time the position muscle group such as domination shank and foot, therefore needed for the transcutaneous electric nerve stimulation of this position, power consumption will be generally less than Neuromuscular
Meat electricity irritation.
Relatively fewer to the research of deep veins of lower limb hemodynamic effects about different parameters of electrical stimulation.Griffin etc.
People is based on forefathers' accumulation to electricity irritation prevention of deep vein thrombosis effect disquisition, and the electricity irritation that have studied different frequency acts on little
Leg muscle, on blood flow and the impact of Maximum velocity, finds after electricity irritation frequency is more than 5Hz, intravenous peak value blood flow
Speed raises with the continuation of stimulus frequency and is gradually lowered, and shrinks corresponding blood flow every time and decrease；Whole process every point
The blood flow of clock then gradually rises with the rising of electricity irritation frequency.And about other parameter of electricity irritation, as electrical stimulation waveforms,
Pulsewidth, amplitude etc. all without reference to.It addition, these researchs when used in electrical stimulation apparatus be all non-to be exclusively used in deep vein
Bolt prevention, although some stimulator is powerful, but expensive and non-portable, is not suitable for daily domestic.
Domestic there is no about the electricity irritation product being exclusively used in deep venous thrombosis prevention, and the relevant product on market abroad
Product, one is valuable product, unsuitable for the routine use of domestic average family.The electrostimulator that two is external is based on west
Side's ethnic group body constitution design, but because ethnic group body constitution between east and west differs greatly, so the parameters of electrical stimulation obtained may be not appropriate for
East ethnic group.Therefore, the portable dedicated electrostimulator developing applicable compatriots' body constitution is just particularly important.
