In many medical applications, the medicine or water needs to be infused over a period oftime. The systems also need fully involvement from the physician to monitor the delivery rate and control the amount of rate by adjusting the device manually. Most of the delivery system is an open loop system where the rate is set basis of the past experience, mathematical computation and trial and error. This might lead to the human error with wrong collected data such as mistake in decimal place dose. Based on the problems, this project is done to replace and enhance the open loop systems by using the automated closed loop system. Basically, this project is to create a medicine delivery system with response to changes in patient's body. The change in patient's body is referred to the temperature. Basically, athermistor sensor is used to detect the changes in the temperature by placing it at the human skin. Then, the signal from the sensor is sent to the PIC microcontroller to control the medicine delivery by automatically adjusting the pump movement. The microcontroller evaluates the received signal and displays the value in degree Celsius on the LCD display. The overall delivery system is fully automated controlled by the controller which depends onthe human body temperature changes.
