|Title:||Development Of A Neonatal Incubator Analyzer [desenvolvimento De Um Analisador De Incubadoras Neonatais]|
|Abstract:||Although designed to benefit premature newborns (NB) by creating an artificial environment close to the uterine conditions, the use of neonatal incubators may expose the NB to several sources of risk. Periodic inspections for verification of minimum requirements of performance and safety can identify these and their degrees of impact, helping to minimize them. In order to automate the metrological evaluation essays in neonatal incubators, we present the development of an analyzer with the capacity to perform all measurements of the variables defined in the standard NBR IEC 60601-2-19 and communicate them to a computer allowing the transmission of measurement data and reception of commands for remote adjustment. The development of this system creates a nationalized alternative with cheaper and more suitable features for the metrological tests required. As a result, we obtained a micro-controlled portable and useful modular prototype, which measures temperature, relative humidity, oxygen concentration, acoustic noise and air speed. The calibration results show that the maximum relative error and measurement uncertainty for the subsystems of temperature, relative humidity, acoustic noise and O 2 concentration were respectively (-0.42; 0.05 °C), (±0.72; 0.24%) RH, (-5.17; 0.68 dB) and (1.28; 2.2%). These results indicate that the analyzer presents a metrological quality compatible with the regulatory requirements established.|
