Desing and Test of an Incubator Analyzer

Abstract

Incubators are cabins that provide the environment with necessary conditions for premature or newborn babies, and they are designed to allow monitoring and care of the baby. The incubator analyzer is the analyzer that shows the performance of the incubator. Knowing how close the values of a medical device are to the actual values is very important in the treatment process. To ensure the accuracy of medical devices, tests and controls are required. As a result of periodic tests and controls, it is possible to reduce the risks by preventing incorrect measurements. If the temperature, humidity and oxygen sensors of the incubators are measured incorrectly, the baby's life would be threatened. This study aims to determine the design requirements of a single incubator analyzer that measures heat, oxygen and humidity in the incubator and to design an analyzer. The general design of the incubator analyzer consists of a battery circuit, a microcontroller, a liquid crystal display (LCD) screen, five temperature sensors, a humidity sensor and an oxygen sensor. Incubator standards of our country and EU has been reviewed according to the design. In addition, within the scope of the project, the sensors in accordance with the standards have been researched and determined, but due to their high cost, alternative sensors are preferred. By that the design of the analyzer can be a model for the actual device. Proper firmware is programmed for temperature, oxygen and humidity sensors, and data from those sensors are processed and displayed on a LCD screen. Also a suitable case is designed by computer aided programs. The analyzer is tested in incubators and functioned properly. With this project, it is determined that a cost effective incubator analyzer can be designed and with more sensitive sensors proper standards can be achieved. This project can be a model for incubator analyzer design.
