Design and Development of a Temperature Controlled Blood Bank Transport Cooler

The transportation of blood is one of the most important issues in the hospital and healthcare sector since the blood bags have to be kept within a certain range of the temperatures for the entire travel time in order to maintain blood quality during transportation. Therefore, the objective of this work is to design, develop and construct a temperature controlled blood bank transport cooler to maintain the properties of blood for transportation within the hospital. The developed blood bank transport cooler uses thermoelectric peltier cooler to create coolness and a microcontroller with Proportional-Integral-Derivative (PID) controller is used to control the temperature in the blood bank cooler within the range between 2°C and 8°C. The current temperature in the cooler is monitored on the LCD display and the notification as light and sound will be activated when the current temperature is out of the desired range. To verify the performance of the developed blood bank cooler, the temperature measured from the temperature sensor of the developed blood bank is compared with the temperature measured from the temperature calibrator. The results show that the measurement errors are within ±10.984%, which is in the acceptable range according to the standards of the World Health Organization (WHO).
