dc.description.abstract This thesis presents the design of an electronic circuit capable of detecting and measuring the concentration of SulfHemoglobin (sulfHb) in blood. Levels from 0.2%, to above 3% of contamination are measured can be measured to detect Sulfhemoglobinemia. Detection was designed using different analog and digital modules, capable of measuring light intensity variations related to the concentration of SulfHb in the blood sample. The proposed system registers the current-to-voltage changes produced by the absorption and fluorescence emission spectrum of the sample, allowing the detection and measurement of SulfHb percentage concentration in blood. Obtained results demonstrate that the designed circuit is capable of detecting the absorption and fluorescence emission spectrum of the sample. Comparison between absorption and emission detection between the proposed circuit and other experimental work is shown.
dc.description.abstract Esta tesis presenta el diseño de un circuito electrónico capaz de detectar y medir la concentración de SulfHemoglobina (sulfHb) en sangre. Se miden niveles desde el 0.2 % hasta más del 3 % de contaminación para detectar Sulfhemoglobinemia. La detección se diseñó utilizando varios módulos digitales y análogos capaces de medir las variaciones de intensidad de la luz relacionadas con la concentración de SulfHb en la muestra de sangre. El sistema propuesto registra los cambios de corriente a voltaje producidos por el espectro de absorción y emisión de fluorescencia de la muestra, permitiendo la detección y medición del porcentaje de concentración de SulfHb en sangre. Los resultados obtenidos demuestran que el circuito diseñado es capaz de detectar el espectro de absorción y emisión de fluorescencia de la muestra. Se muestra la comparación entre la detección de absorción y emisión entre el circuito propuesto y otros trabajos experimentales.
