Abstract:
Objective:To construct a dispatching system based on ultra wide band(UWB)positioning technique,so as to enhance dynamic management capabilities for equipment and clinical response efficiency.Methods:The dispatching system based on UWB positioning technique for emergency equipment included internet of things(IoTs)perception layer of network,network layer,data service layer,and business application layer of intelligently medical equipment,which integrated the positioning technique with UWB centimeter level and the deep Q-network(DQN)algorithm,and it can realize real-time localization and intelligent dispatching decisions for equipment.The used thirty-five emergency equipment in the intensive care unit(ICU)ward of Eastern Branch of Ningbo Medical Center Li Huili Hospital from January 2023 to December 2024 were selected.Based on different management modes,25 equipment using conventional manual dispatching during January and June 2023 were divided into control group,while 25 equipment using the UWB dispatching technique-based dispatching system during July and December 2023(included 15 equipment of the original control group and 10 new equipment at later stage)were used as observation group.The dispatching efficiency,utilization rate,positioning precision,and maintenance efficiency of equipment between two groups were compared.Results:The dispatching time for equipment in the observation group was(7.2±0.8)min,which significantly shorter than(12.2±1.5)min in the control group,and the difference was significant(t=18.34,P<0.05).The distance of movement,and response time for fault in the observation group were significantly lower than those in the control group,and the utilization rate of equipment was significantly higher than that in the control group,and the differences were significant(t=15.67,14.28,6.92,P<0.05).The repair rate for fault in the observation group was significantly higher than that in the control group,and the difference was significant(x2=7.80,P<0.05).The positioning error of the system is(35±10)cm.Conclusion:The UWB-based dispatching system can significantly optimize the dispatching process for resource of emergency equipment,which can improve utilization and management efficiency for equipment.It can provide reliably technical support for rapid response in clinical emergency.
