| contents | Digital blood pressure monitor Rosendo Fuentes González Miguel Angel Bañuelos Saucedo Ingeniería Altera applications Blood pressure monitor Biomedical instrumentation In this work we present a blood pressure monitor which measures both the high blood pressure (systolic pressure),and the low blood pressure (diastolic pressure). It is a semiautomatic meter because the inflation of the occlusivecuff is carried out in a manual way. The transducer used is a piezoresistive silicon pressure sensor integrated onchip which provides a proportional voltage to the input pressure, with a measurement range from 0 to 50 kPa (07.3 PSI). The oscillometric method is employed, which consists on detecting the oscillometric signal on brachialartery, being processed at each pressure step, when the cuff is gradually deflated. Signal sampling is carried out ata rate determined by the heart rate.In order to program the digital electronics of the circuit we used Altera tools, with the compiler MAX-PLUS II, andthe device selected to implement the design was an EPM7128SLC84-15 CPLD (Complex Programmable LogicDevice) 2004 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47402305 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.2 |
