Blood Bank Application for Donor’s And Acceptor’s Using Android App ABSTRACT In health care services, blood donation is a complex process and consumes time to find some donor who has the compatibility of blood group with the patient. We developed android based blood donation application as blood bank solutions to establish a connection between the requester and donor at anytime and anywhere. The objective of this application is to provide the information about the requested blood and number of available donors around those localities. The purpose of this study was to develop a blood management information system to assist in the management of blood donor records and ease/or control the distribution of blood in various parts of the country basing on the hospital demands. Without quick and timely access to donor records, creating market strategies for blood donation, lobbying and sensitization of blood donors becomes very difficult. The blood management information system offers functionalities to quick access to donor records collected from various parts of the country. Software Requirements: Front End: XML Back End: JAVA, Firebase Android Tools: IDE: android Studio Android Emulator Hardware Requirements: Processor : Intel 3 Installed memory (RAM) : 4 GB Hard Disk : 500 GB Operating System : Windows 7,8,10 - 64 bit Existing Definition: People will go from one blood bank to another to get the blood which is time-consuming and sometimes not able to reach at the time. In some blood banks, sometimes we get the blood but that is not sufficient so we need to search for another blood bank for more blood. If some person wants to donate the blood, he/she needs to come to the bank and need to fill the form then the first doctor will check his blood group after that he will allow donating. Suppose there is some patient who needs blood urgently then how you come to know about this condition, you will not even able to reach the patient. Proposed Solution: The blood management information system offers functionality to quick access to donor records collected from various parts of the country. It enables monitoring of the results and performance of the blood donation activity such that relevant and measurable objectives of the organization can be checked. It provides to management timely, confidential and secure medical reports that facilitates planning and decision making and hence improved medical service delivery. The reports generated by the system give answers to most of the challenges management faces as far as blood donor records are concerned.
