Objectives of the Work

The objectives of the research are:

• To find the drawback of existing blood flow

controllers

• To design an automated blood flow monitor which

is able to measure blood flow rate

• To build a low cost blood flow controller

Introduction

• The requirement for health care are rapidly rising with the

continuous growing of the world population.

• Tremendous success in medical technology has been
• bserved

with the rapid advancement

• f

sensor microcontrollers, and computers’ prompt development.

• Numerous technological innovation designs are taken for the

advantage of medical service improvement.

• The actual goal of this kind of function is to assist the daily

life of a patient through building an automated and price efficient blood tracking method.

• Automatic blood flow is developed to assist the doctor or

nurse to monitor and control the blood flow rate.

Working Principle

• Microcontroller is used as the controlling unit.
• The developed flow sensor is attached to the neck of the

blood bottle.

• The output signal from the flow sensor is amplified and

then feed to microcontroller’s interrupt pin to calculate drop interval.

• A high precision blood flow controller is attached with

blood delivery pipe.

• If any mismatch detected, the microcontroller sends

control signal to blood flow controller in order to correct.

automated blood control device using smart phone for medical application successfully achieved.

• In terms of performance and reliability, this project has

provided an accurate method of blood flow controlling compared to the existing researches.

Future Works

Some additional features may be added to this system:

• PID controller can be added to make fast

and accurate controller.

• IoT technology may be used here
• Heart pulse rate sensor
• Blood pressure sensor
• Other type of fluid flow can be measured
