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.
1. INTRODUCTION:
BLOOD 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 experiments. It activates the clamp and stops the rocking movement of plate when weight in blood bag is presented.
It is approximate to the actual design but more function of the instrument by extra features like flow detector, flow rate measurement etc. So, the component specifications may differ from the actual one.
2. REQUIREMENT OF PROJECT:
As we all know that blood collection monitor is very helpful for collection of accurate blood, it’s a compact instrument that provide smooth and gentle rocking movement of homogeneous mixing with anti-coagulant, so in modern lifestyle most of the doctors prefer these types of instrument for collection of blood very accurately.
Blood collection monitor is very helpful to donate blood. what happen in past that there’s no such types of instruments were present so it is inaccurate random process for doctors to take blood from the donor and also sometimes improper mixing with anti coagulant lead to waste the valuable donated blood that process may not helpful to accurately blood collection.
With the help of this modern instrument it is very easy for doctors to take the blood from the donor, and through this instrument may also required less effort. Collection of blood accurately and safely.
