Improved Multifunctional Electrical Stimulator for Microprocessor Control for Surface Stimulation of Semi-Intolerant Patients

摘要

The system of the present invention consists of a single pulse source and an amplifier 103 for outputting various electrode pulse strings and is generated and controlled entirely under the microprocessor 104 and can be operated upright and walkable in the relaxed state of the upper muscular dystrophy patients The microprocessor of the microprocessor optionally performs multiplexing of the pulse train to provide their selective distribution to the various surface electrodes attached to the patient's skin at the appropriate stimulation location. It controls pulse lock, pulse duration, pulse amplitude and pulse shape. Furthermore, the system can calculate and activate (audible and / or visual) alert signals to alert the patient when it approaches its maximum output. This occurs when muscle fatigue occurs so that no further increase in the stimulation level can keep the patient standing.;The system provides an automatic fail-safe and override capability to assist in assuring that the patient will not fall in case of failure or misbehavior of the main circuit or system. This is an important capability because the system can be used for outpatient patients who lack a sense at the lower extremity.
