Development Of Intelligent Monitoring System For Human Intravenous Infusion

Intravenous infusion is a commonly used method in hospital treatment.For the monitoring of the infusion process,the current traditional hospital management mainly relies on manual processing.This mode requires patients to always pay attention to the infusion status and notify the medical staff by themselves.It is prone to the shortcomings of the end of the infusion and the delay in handling abnormal infusion.With the development of the Internet of Things technology,real-time monitoring of the infusion process in the ward combined with wireless sensor communication and remote data transmission can provide a new management model for hospital infusion management and make hospital treatment more intelligent.Therefore,this paper designs an intelligent infusion monitoring system based on Arduino and Zigbee,which aims to construct a wireless sensor network to realize real-time monitoring of infusion parameters and patient physiological characteristics during the infusion process.The main content of this article is as follows:1.Designed the infusion monitoring node.The system combines the photoelectric sensor,and uses the Arduino Nano processor to identify the drop of the liquid during the infusion process,and calculates the drop rate and the remaining progress of the liquid through the counting of the liquid and the interval between two adjacent liquids.At the same time,the infusion data is displayed,and the infusion status is judged and alarmed based on the data.2.Collection of patient heart rate information.The system adopts the photovolume method,selects the sensor to collect the patient’s heart rate signal during the infusion process,and performs algorithmic processing to extract the corresponding feature points according to the collected signal waveform.Then the processor calculates the patient’s heart rate data,and then sends it to the host computer software through the wireless transmission module for display and data storage,which provides a basis for subsequent reference by medical staff.3.Zigbee wireless communication network design.The system establishes a Zigbee wireless sensor network and sets up the terminal nodes,router nodes and coordinator nodes of the system to realize the communication and transmission of data between each node.At the same time,according to the actual working environment of the hospital,the system determined the mesh network as the network topology of the system,and designed suitable transmission protocol frames and communication workflows.4.Host computer software management platform design.The upper computer software system is mainly developed on the Microsoft Visual Studio platform using Visual Basic.NET language to realize the display and storage of infusion data and patient heart rate data on the nurse side.At the same time,it combines personnel management,patient file management and patient file management designed with database technology Interactive interface such as heart rate information query.The medical staff can monitor the infusion process and file query management through the developed host computer system.5.Monitoring system testing.The function and performance of the system are tested.Finally,the reliability of the system is proved by analysis.Among them,the function test of the system includes data display and status warning prompt,while the performance test is mainly divided into the accuracy test of communication performance and drop speed.Finally,the results show that the system can monitor the patient’s infusion status in real time,effectively reduce the workload of medical staff,and improve the efficiency and intelligent level of hospital infusion management.
