Need of blood is drastically increasing. Per annum we require 5 million blood units and only 5 million blood units are available. This is the major drawback in case of emergency blood required some patients have daily need of blood those suffering from cancer. Even though the technology is developed still we fail to bring blood donors and recipients on the common platform. Accidents cannot be predicted. There may be blood requirement at any moment so direct communication between donor and user becomes necessary to avoid longer time span in the availability of blood [1]. Basically user/patient needs to send the request with required blood details from database data will be fetched and notification will be sent to the respective blood donor. This paper consists the object tracking system diagram, system flow and software design in section II. Kalman filter algorithm and its mathematical equations are explained. The process of managing the blood bag that is received from the blood donation events needs a proper and systematic management that is done by the blood banks. As the blood is related to someone’s life so the bags of must be handled with care and treated thoroughly. The blood consists of different blood constituents and every constituent of blood is having a specific function. Statistics say that in our India every two seconds someone needs a blood transfusion. The Blood transfusions are used for trauma victims - due to accidents and burns - heart surgery, organ transplants, women with complications during childbirth, newborns and premature babies, and patients receiving treatment for leukaemia, cancer or other diseases, such as sickle cell disease and thalassemia [6]. The different blood constituent is applied to the patient for different type’s disease given in table1. India today faces a blood shortage of 10% relative to its blood requirements. It means that we require covering a shortfall of over 12 lakhs of blood units. Given that the eligible donor population of our India is more than 512 million, this deficit is surprising. Every day more than 1200 road crashes occurring in our India, 60 million trauma induced surgeries are performed in the country every year. Near about 230 million major operations, 331 million cancer-related procedures like chemotherapy and 10 million pregnancy complications all these require the blood transfusion [9]. Besides all this, the patients which are for sickle cell anaemia, thalassemia and haemophilia require large quantities of blood daily. Another reason for the shortage of the blood supply is the ban on payment to blood donors that was enacted in 1995. Previously near about one third of the blood supply was from paid donors. But with the ban, both private and government hospitals have faced a larger shortage in the blood supply. Automated online blood bank database: A number of online blood bank databases are available, however none of them offer the capability for a direct contact between the donor and recipient. This is a major drawback particularly in cases where there is an urgent need of blood. Our project aims to overcome this communication barrier by providing a direct call routing technique using Asterisk hardware. A blood bank database is created by collection of details from various sources like Blood banks, NSS, NGO's, hospitals and through web interface. The data collected will be maintained in a central server. This central server will be associated with a Toll-free number that can be used to connect to it. The willingness of donor and the closeness of the donor to the place from where the call is coming are also accounted for in defining this algorithm. Based on the algorithm the most eligible donor is found out. From the server the call from the required person is routed to the eligible donor's number. Such a system considerably cuts down on the overheads involved in referring to an online database and then calling the donors and verifying their willingness at a time when there is a critical need for the blood.

   

The main objective of this project is:

1. To design an automated blood bank system.
2. To send the patient details to donors when there is requirement of blood.
3. The details are sent through GSM modem.

The major building blocks of this project are:

• Battery Supply(9v,12v).
• Power supply.
• Raspberry Pi processor.
• GSM modem
• SD card.

Software’s used:

1. Raspbian OS.
2. Python language.
3. Express SCH for Circuit design.
