Design and implementation of a low-cost automated blood flow control device through smart phone for bio-medical application

This paper reports on the design and implementation of an automatic and low cost blood flow controlling device based on microcontroller through smart phone. It is able to assist the medical personnel to monitor and control the blood flow rate to the patients using mobile phone. The heart of the controlling part is the microcontroller unit in co-ordination with the flow sensors, stepper motor and Bluetooth module. The flow sensor is attached to the neck of the blood bag to count the actual number of drops of blood per minute. Its output signal is amplified and fed to the microcontroller's input pin to continuously check whether the blood flow rate is equal to the given set-value or not. If any mismatch is detected then the microcontroller rotates the stepper motor to adjust the blood flow rate with the set-value. The designed device is implemented and tested to evaluate its real time performance. From the test data, the average experimental accuracy of the system is found over 99%.
