MEDICINE/WATER DELIVERY SYSTEM WITH RESPONSE TO CHANGES IN PATIENT'S BODY

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.
