Abstract:
Blood Collection Monitor is helpful for accurate blood collection; it’s a compact instrument to provide smooth and gentle rocking of homogenous mixing with anti coagulant ; i.e. without clot formation of blood cells during collection of blood from a donor.
BLOOD COLLECTION PROCESS IS HAPPENING IN DIFFERENT ENVIRONMENTS. THE CHALLENGE TO PHLEBOTOMIST (One who draws blood for analysis or transfusion) IS TO MAKE EACH BLOOD COLLECTION PROCESS COMFORTABLE AND SAFE WITHOUT COMPROMISING QUALITY. BLOOD COLLECTION MONITOR COMES INTO ROLE HERE; IT IS SPECIALLY DESIGNED TO MAKE STANDARDIZED HIGH QUALITY BLOOD COLLECTION WITH REDUCED WORK LOAD OF PHLEBOTOMIST. BLOOD COLLECTION MONITOR ENSURES CORRECT VOLUME OF BLOOD COLLECTION WITH CONSTANT AGITATION FOR BETTER COMPONENT YIELD.
SO, THE CORRECT VOLUME OF BLOOD COLLECTION AND MIXING OF THE BLOOD AND ANTICOGULANT GENTLY AND PERIODICALLY DURING COLLECTION OF BLOOD; CAN BE DONE BY BLOOD COLLECTION MONITOR.

LOOD COLLECTION MONITOR is an advanced device which is aimed to collect the blood prior to collection with use of latest technology in place of earlier, insufficient, conventional methods i.e. without accurate weight by using random movement.
The main concept behind this project is use of mechanically provide rocking movement to blood and proper mixing with anticoagulants. Also restrict the blood flow from donor when particular limit is reached. I.e. 350ml or 450ml.This is done by load cell and by comparing signal activate the stopping clamp is activated.
As, sensing range of load cell is in mill volts; directly the signal can be given as input to the circuit because it will provide insufficient output. So, it is required to be properly amplified. So, the block diagram is designed taking into account this matter. Then comparing it with reference signal which is decided by many
