Wireless infusion monitoring system and monitoring method based on multi-sensor fusion

Abstract

The invention discloses a system and a method for wirelessly monitoring transfusion on the basis of multi-sensor fusion.The system comprises transfusion monitoring nodes, a transfusion monitoring center and mobile terminals.Transfusion progress and speeds are comprehensively monitored by the transfusion monitoring nodes, data of the various monitoring nodes are comprehensively processed and managed by the transfusion monitoring center, the mobile terminals can access the monitoring center so that transfusion conditions of patients can be queried in real time, and the transfusion monitoring nodes, the transfusion monitoring center and the mobile terminals are wirelessly connected with one another.The system and the method have the advantages that medicine liquid data are simultaneously acquired by weight sensors and infrared correlation light sensors of the transfusion monitoring nodes, accordingly, the system and the method are high in precision as compared with a single sensor, and overall progress information and specific dripping speed information can be simultaneously acquired; the transfusion monitoring nodes and the transfusion control center are in ZigBee wireless communication modes, and ZigBee is low in power consumption and cost and high in capacity; accurate transfusion monitoring results can be obtained by means of Kalman filtering by the aid of processes for fusing and processing every two corresponding sensors.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a wireless transfusion monitoring system and a monitoring method based on multi-sensor fusion. Background technique [0002] Intravenous infusion is a very important way of administration in clinical treatment. At present, due to the lack of economical and effective automatic infusion monitoring devices, patients need special personnel to observe the infusion of drugs at any time during the infusion process. The long-term infusion process can easily lead to negligence of patients and accompanying staff. If the inappropriate situation cannot be discovered in time, it may delay the patient's treatment process, seriously threaten the safety of the patient's life and property, and increase the hidden danger of medical accidents. Of course, some automatic infusion devices such as infusion pumps have also appeared on the market, but these devices are complicated and expensiv...

Problems solved by technology

At present, due to the lack of economical and effective automatic infusion monitoring devices, patients need special personnel to observe the infusion of drugs at any time during the infusion process. The long-term infusion process can easily lead to negligence of patients and accompanying staff. If the inappropriate situation cannot be discovered in time, it may delay the patient's treatment process, seriously threaten the patient's life and property safety, and increase the hidden danger of medical accidents.

Of course, some automatic infusion devices such as infusion pumps have also appeared on the market, but these devices are complicated and expensive, cannot be used in large areas in hospitals, and are not convenient for centralized management
