Design of an embedded system of spinal cord stimulator

Abstract

Spinal cord stimulation is a treatment for pain that uses a mild electric current to block nerve impulses in the spine. SCS is used after you have tried other treatments such as medication and exercise and they have not worked. Some activities of the spinal cord are independent of the brain, i.e. spinal reflexes. To facilitate these there are extensive neuron connections between sensory and motor neurons at the same or different levels in the cord. The spinal cord incompletely divided into two equal parts, anteriorly by a short, shallow median fissure and posteriorly by a deep narrow septum, the posterior median septum. This work we designed module of the job of a spinal cord impulse simulator, which reads the vibration through a PIN-B1 and the provisional rules of procedure runs to calculate the pulse counter in a given time. Moreover, the program condition counts per cycle and amplitude in a given time. In addition, the program condition involves output pulses that uses PWM technique, impulses and frequency duty emerging count of impulses input .Finally, this work carried out using BASCOM and PRUTOUS software to stimulate the circuit work and display the results. The results of the stimulator depending on the state of patient when we adjusted the values of the parameters that we need in specific patient state of problem the signal appears as square waveform in the oscilloscope. This research intended to produce new version of spinal cord stimulator, this design will make home usage possible, cheap compared with the other types of stimulators. This stimulator design intended to be flexible and medical experts could adjust to the need and requirement of the patients. The quality of graphic display used and improved.
