# Bluetooth-Based Healthcare Information and Medical Resource Management System
###### Abstract  
This paper presents a healthcare information and medical resource management platform utilizing wearable devices, physiological sensors, and an indoor positioning system (IPS). This platform provides medical healthcare information management based on the physiological information collected by wearable devices and Bluetooth data collectors. The Internet of Things (IoT) is constructed for this medical care purpose. The collected data are classified and used to monitor the status of patients in real time with a Secure MQTT mechanism. The measured physiological signals are also used for developing an IPS. When the patient is out of the safety zone, the IPS will send an alert message instantly by pushing the server to remind the careaker, easing the careaker's burden and offering extra protection for the patient. The presented system also provides medical resource management with the help of IPS. The medical equipment and devices can be tracked by IPS to tackle some equipment rental problems, such as lost and found. A platform for the medical staff work coordination information exchange and transmission is also developed to expedite the maintenance of medical equipment, providing the shared medical information to healthcare and management staff in a timely and transparent manner. The presented system in this paper will finally reduce the loading of medical staff during the COVID-19 pandemic period.

continues to rise, the demand for medical care escalates, and the workload of healthcare workers increases. This, coupled with the declining fertility rate, has resulted in a declining workforce and has highlighted the shortage of medical manpower. In addition to patient care, medical staff in medical institutions also need to manage medical equipment and supplies [13]. Medical devices and equipment such as wheelchairs and crutches are available for rent to people/patients who come to the facility, but people often forget to return them to their original place after using them and may even take them away from the facility. These oversights often cause great problems for medical staff in the management of medical supplies and increase the workload of medical staff. Furthermore, in the maintenance of medical equipment, management staff need to be quickly informed of the maintenance time and status of each piece of medical equipment. For example, in the case of bed management, the statuses of beds, such as not-in-use, in-use, and clearing beds, are required to be updated immediately so that medical staff can clearly have those empty beds for new patients. During the period between patient check-out and bed cleaning, it is often necessary for nursing staff and bed cleaning staff to provide each other with real-time information on the status of beds to improve the overall speed of the bed cleaning process. In the past practice of using telephone contact for bed cleaning, nursing staff may forget, due to their busy work schedule, to notify bed cleaners in time when patients check out, which leads to delays in bed cleaning progress. Therefore, how to provide this shared medical information to healthcare and medical management staff in a timely and transparent manner to enhance the efficiency of medical institutions is an urgent problem for medical institutions today. Therefore, in order to provide a solution to the above challenges, this paper will apply wearable devices in medical institutions and physiological information sensing technology to build a medical Internet of Things (IoT) platform and integrate various medical-related and healthcare-related information through the MQTT (Message Queuing Telemetry Transport) protocol of IoT [14; 15; 16; 17].
