Infusion monitoring system based on LoRa technique

Abstract

The invention discloses an infusion monitoring system based on an LoRa technique, and mainly solves the problems that an existing infusion monitoring system is low in monitoring accuracy, high in power consumption and small in monitoring range. The infusion monitoring system comprises a murphy's dropper, a data acquisition unit, infusion monitoring terminals, an LoRa gateway, a local server, a local server, a thing internet cloud platform, local infusion monitoring and controlling equipment and long-range monitoring and controlling equipment, wherein the data acquisition unit comprises a linear array CCD sensor and a uniform illuminant which are respectively mounted on two sides of the murphy's dropper; input ends of the infusion monitoring terminals are connected with the output end of the linear array CCD sensor, and the output ends of the infusion monitoring terminals are connected with the local server through the LoRa gateway; the output end of the local server is connected with the local infusion monitoring equipment and the thing internet cloud platform; and the output end of the thing internet cloud platform is connected with the long-range monitoring and controlling equipment. According to the infusion monitoring system disclosed by the invention, the infusion monitoring accuracy rate can be increased, the power consumption of the system can be reduced, the monitoringrange can be extended, and the infusion monitoring system can be used for long-range real-time monitoring of the infusion state in hospitals.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion monitoring system, which can be used in a hospital to monitor a patient's infusion state. Background technique [0002] As the pace of life continues to accelerate, infusion has gradually become a commonly used means of disease treatment. According to public data, in my country, the annual infusion volume is tens of billions of bottles (bags), with an average of 8 bottles per person, far exceeding the international 2.5-3.3 bottles, so infusion safety is particularly important in my country. At present, most infusion monitoring is completed by nurses' patrols and patients' active calls. However, in large hospitals, nurses need to patrol a large number of patients, and nurses cannot effectively predict the progress of infusion. When the infusion is completed, they cannot handle it in time, which may cause symptoms such as blood return and air embolism, which ...

Problems solved by technology

However, in large hospitals, nurses need to patrol a large number of patients, and nurses cannot effectively predict the progress of infusion. When the infusion is completed, they cannot handle it in time, which may cause symptoms such as blood return and air embolism, which will affect the health of patients. There is an urgent need for a device that can realize intelligent infusion monitoring to solve the above problems

[0003] At present, there are many devices on the market that can realize automatic infusion monitoring, but they generally have the following disadvantages: 1) The accuracy of the monitoring method is low, which is likely to cause false alarms or missed alarms, reduce the efficiency of medical care and may cause medical accidents; 2) Monitoring The information can only be obtained in the ward or the nurse's desk, and remote real-time monitoring cannot be realized, and it is still not intelligent enough; 3) The power consumption is too high, and the frequency of charging or replacing the battery of the monitoring device is frequent; 4) Traditional ZigBee, WIFI, Bluetooth, etc. are used The wireless transmission method has shortcomings such as short transmission distance, small number of connections, weak penetration, and high power consumption.

[0007] The shortcomings of this patent are: 1) WIFI communication technology is adopted, and the communication distance is relatively short. When the data receiver of the nurse's station is far away from the ward, reliable communication cannot be realized; the capacity of the WIFI networking network is small and cannot be applied to a large number of Management of bed infusion; high power consumption, prominent power management problems

2) The monitoring of infusion status is seriously affected by the region, and it can only be performed in hospitals or near hospitals, and remote real-time infusion monitoring cannot be completed
