###### Abstract  
Health-care-sector-related activities are more accessible and faster as a result of technological development. Technology such as the Internet of Things (IoT) can work with blood bank services to manage and provide healthy blood in emergencies. However, there are many problems in blood bank management and inventory monitoring, especially in developing countries as compared to developed ones. The lack of an adequate and safe blood supply is a major limitation to health care in the developing world. The instability of the electric power in developing countries may lead to a temperature departure from the recommended for keeping blood inventory, and the use of manual systems, which are characterized by time and resource exhaustion and human mistakes, augments the management problems. This study aims to introduce a reliable, practical application to manage and organize the blood bank, manage donor information, monitor inventory, and obtain matching blood types as quickly as possible. The proposed system was designed and implemented in two parts: using Web technology for enhanced data management and using an IoT sensor for blood inventory temperature monitoring in real time. The test stage helped us to measure the Web application's functionality with sensors, and the results were encouraging. Obtaining and monitoring blood bank data were made easier in real time by using the black box method for functionalities testing. The evaluation step was performed using a questionnaire instrument based on three parameters: Satisfaction, Effectiveness, and Efficiency. The questionnaire was answered by 22 participants working in the blood bank management field. The results indicated that end users generally responded positively to the system which improved blood bank administration and services. This indicated efficiency of the application and the desire to adopt it. Integrating the two technologies can enhance usability and applicability in the health care sector. blood bank; blood bank management system; developing countries; internet of things; Web application +

According to the World Health Organization (WHO), the availability and safe use of blood and blood components vary between developed countries and developing countries [9]. There are significant limitations in health care systems in developing countries [2], such as those in the Eastern Mediterranean Region (EMR), where blood services face considerable problems related to the availability of blood and the assurance of its quality and safety. Unfortunately, despite the benefits of new technologies which improve and speed up the work of the BBS, these systems are not updated, especially in developing countries. This has created many challenges, barriers, and limits, such as reliance on human intervention and problems in managing donor information, periodic reports, and matching blood types for transfusions to patients [10; 11]. Moreover, the lack of coherence in the database shared by blood donation centers leads to a lack of the most recent information, and the patient is unable to obtain the necessary and matching amount of blood on time [12]. Moreover, the irregularity of the electricity supply in developing countries mainly affects the health sector [13]. Unstable access to electricity results in the storage of blood outside WHO-recommended temperature limits. Based on blood safety and availability, according to the WHO Fact Sheets, the blood collection rate is less than 10 per 1000 people in 6 of 21 MENA regions, including Iraq. In low-income countries, children under 5 years account for up to 54% of all transfusions, while patients over 60 years account for up to 76% of all transfusions in high-income countries. The average blood donation rate is more than nine times greater in high-income countries than in low-income countries [11]. Iraq is country that has suffered from wars, terrorist operations, and combative spread, and it is considered an ongoing conflict zone.
