Design and implementation of a positioning management system for mobile equipments in operation room based on Bluetooth low energy positioning technology

Abstract: Objective To develop a positioning management system for mobile equipments in operation room based on Bluetooth low energy positioning technology, which is used to track, check and manage common and expensive anesthesia equipments in operation room. Methods The system was composed of hardware and software. The hardware mainly included LAN switch, Bluetooth host device, Bluetooth slave device and server and the software mainly includes database and user display interface. The Bluetooth signal of each room was collected by LAN, and then written into database through the server. The user could locate the required equipment by searching it on the computer display interface. Results The system which had good performance in equipment positioning and was stable in running could obtain the working position of medical equipments or instruments, with the advantages of simple and clear interface and lower frequency of hardware maintenance. Moreover, the system was small in size, and it could be used for 2 years once fully charged. Conclusion The proposed system solves the problem of equipment positioning in operation room. At present, it has been used in clinic and achieves satisfactory results.
