Sistema para ensaio de funcionalidade de incubadoras neonatais

Abstract

This work presents a prototype based on a microcomputer to assess the performance of newborn incubators in a semi-automatic way. It carries out the tests described by the Section 8 of the NBR IEC 601- 2-19/1999. The developed electronic circuit acquires data from the sensors using a microcontroller. A set of sensors are used: Five for temperature, one for humidity and one for air flow. The sampled data is sent to a PC via Bluetooth. The software running on the PC manages the data sampling, as well as guides the user through the test procedure by means of messages and sound alerts at the end of each stage. The acquired data is shown on the screen and also stored into a database that can be locally or remotely accessed. At the end, the results are presented on a graph where the measurements (temperature, humidity and air flow) performed during the whole test can be seen. The procedure to calibrate the sensors and the tests carried out with the developed system are presented. © Springer-Verlag Berlin Heidelberg 2007.
