1. THE INTELLIGENT BLOOD COLLECTING APPARATUS
BASED ON INTERNETWORKING
The paper chiefly introduces the apparatus of intelligent blood-collect based on
internetworking. The apparatus uses fingerprint identifying technology to distinguish the identity
of the operator and radiofrequency identification technology to input the information of the
donator. The apparatus can measure collected blood. So it accomplishes automation of collecting
blood and increases reliability of collecting blood. The interface of internetworking is embedded
in the intelligent blood collecting apparatus. And the intelligent management of blood collecting
comes true.
Proposed system:
Blood collecting which is the important segment of blood donation directly relates to the
health of the donator and the persons using the blood. The blood-collecting apparatus is strictly
desired especially. The apparatus introduced in this paper combines the technology of computer,
measurement, electronic and communication. Main properties of the apparatus are: (1) Blood
collecting is completed automatically and its collecting process and result are showed in liquid
crystal display. (2) The RFID reader is used to input the relative information of the blood
donator. (3) Use fingerprint input to identify the operator for collecting blood the apparatus can
measure collected blood. (4) Monitor the pulse of the donator to avoid accidents using BP
sensor.
In this project, the fingerprint scanner is used to identify the operator for collecting blood
and RFID reader is used to identify the donator information to get from RFID tag and given
information to ARM processor. The BP sensor is used to check blood pressure of donator. If BP
is normal only blood will be collected from donator, blood collecting key is on to collect the
blood , the blood is collected from patient as well as monitoring donator BP condition and level
of blood collecting apparatus using weight sensor. ARM processor stops Collection blood

2. immediately either any abnormalities in BP value or collection apparatus is filled using sensed
by weight sensor.
