Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
See Fig. 1 and Fig. 2, a kind of portable tibialis anterior electrostimulator, four interfaces comprising shell 1, be arranged on Master control chip in shell 1 and battery, be arranged on display screen 2 on shell 1 and button 3 and be arranged on shell 1; Four interfaces are connected to stimulating electrode line 5, plantar pressure sensor 6, trigger 7 and power interface; Stimulating electrode line 5 is connected with stimulating electrode sheet; Plantar pressure sensor 6, button 3 are connected with Master control chip input; Master control chip outfan is connected with display screen 2 and stimulating electrode sheet; Trigger 7 is connected with Master control chip input.Button 3 comprises power key, advance key, back spacer, increase key successively, reduces key and acknowledgement key.
Portable tibialis anterior electrostimulator of the present invention is a hand held medical device, be mainly used in rectification and the treatment of hemiplegic patient foot drop gait, the tibialis anterior of patient is stimulated by electricity irritation, reach the object of correcting food drop, electricity irritation can be had and triggered by the plantar pressure sensor 6 in patient vola, also can be triggered by trigger 7.
By display screen 2 display menu and treatment parameter, by button 3 choice menus and adjustment treatment parameter.Conventional treatment parameter can be stored as therapeutic scheme.
One passage electricity irritation adds a passage plantar pressure collection; Stimulus waveform: asymmetrical square wave, Parameter adjustable also can be preserved, automatically containing stimulus frequency, pulse width, rise time, fall time, activation pressure threshold value, trigger delay time etc.; Button 3 and menu operation, button 3 wakes display screen 2 up, Current Regulation button 3; Lithium battery power supply, shell fixation clamp hangs in belt or leg strap
Performance
Electrically stimulating parts
Export stimulus intensity: 0mA ~ 99mA is adjustable.
Export stimulus frequency: 01-99Hz is adjustable, error: ± 15%.
Output pulse width: 30-400 μ s is adjustable, error: ± 30%.
The rise/fall time: 0.01-9.99S is adjustable.
Plantar pressure collecting part:
Sample frequency 100Hz
Sampling precision 12
Pressure limit: 0-400N
Pressure measurement accuracy: ± 10%
Stimulate needs according to carrying out dynamic electric in hemiplegic patient's gait processes, portable tibialis anterior electrostimulator of the present invention, fuselage weight only has 150 grams, can hang in belt or leg strap.Be mainly used in rectification and the rehabilitation of hemiplegic patient foot drop gait, the tibialis anterior of patient is stimulated by electricity irritation, reach the object of correcting food drop, electricity irritation can be had and triggered by the plantar pressure sensor 6 in patient vola, and also can trigger liftoff beginning of heel by trigger 7 stimulates, and stimulates and rises to about 0.2 second of maximum time, then keep, start slowly to reduce to stimulate to heel contact, set level to foot and stop completely, about 0.2 second fall time.The liftoff of heel to be detected by plantar pressure sensor 6 with landing, and threshold value can regulate.Rise time and fall time scalable, range of accommodation is from 0.1s-10s.
Electrostimulator operational approach of the present invention is easy, and by 3.2 cun of color LCD screens, resolution 320*240 liquid crystal display screen display menu and treatment parameter, by button choice menus and adjustment treatment parameter.Design five buttons 3, adjust current intensity, stimulus frequency respectively: from 2Hz to 100Hz, pulse width: from 50 μ s, to 400 μ s, rising and falling time: from 0,0.1, to 10S current intensity: from 0 to 100mA, activation threshold value: from 0 to 99N.After setting current intensity, pin " determination " to start to stimulate, unclamp and stop stimulating, whether measuring current intensity is suitable.Conventional treatment parameter can be stored as therapeutic scheme.
" optimum configurations " state is, parameters in this case, measuring current intensity after start.Under " optimum configurations " state, select " beginning " by confirming button, enter life's work state.All optimum configurations are complete, automatically preserve upon start, this parameter of start next time acquiescence.After life's work, 30S is without button operation, automatically closes display screen 2 backlight, wakes display screen 2 up by any key.After formally starting working, all parameters all can not adjust again, must turn back to " optimum configurations " state and could adjust parameter again.
