Infusion set monitoring system and monitoring method

Abstract

The invention relates to an infusion set monitoring system. An infusion bottle is hung on a precise pull force sensor, the real-time weight of the infusion bottle is collected, output and input to an analog-digital conversion module after being amplified, the output end of the analog-digital conversion module is connected with a single-chip microcomputer, after internal calculation of the single-chip microcomputer, infusion remaining weight, flow speed and remaining time data are output in real time, the single-chip microcomputer communicates with an Android smart phone through a Bluetooth module, the Android smart phone displays the infusion remaining weight, the flow speed and the remaining time information in real time, and the single-chip microcomputer outputs a warning signal to an LED lamp to be displayed. A data collection and display instruction is directly sent on the Android phone, so that computer management of hospital infusion information is facilitated. Testing precision is high, power is supplied by a battery, and use is convenient. A photoelectric sensor is not needed, installation is convenient, and cost is low. By the adoption of an anti-interference iteration algorithm, reliable prediction of infusion flow speed and infusion remaining time is achieved. A Zigbee wireless interface is preserved, so that subsequent integration of the infusion set monitoring system and an existing doctor and patient management computer information system of a hospital is facilitated.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a monitoring system and a monitoring method for an infusion set. Background technique [0002] At present, when patients are in the hospital or at home for infusion, because they cannot accurately know the remaining time of infusion, they often feel anxious and waiting during the infusion process; on the other hand, most nurses also estimate the remaining time of infusion through experience, which brings a lot of inconvenience to work . How to accurately measure the remaining weight and remaining time of the infusion during the infusion process is a problem worthy of research and urgently to be solved. Contents of the invention [0003] The present invention is aimed at the problem of heavy infusion workload in hospitals, and proposes an infusion device monitoring system and monitoring method, which can measure the remaining weight of the infusion in real time (accuracy 0.1g, abou...

Problems solved by technology

[0003] The present invention is aimed at the problem of heavy infusion workload in hospitals, and proposes an infusion device monitoring system and monitoring method, which can measure the remaining weight of the infusion in real time (accuracy 0.1g, about 5 drops) and remaining time (accuracy 10S), when When the remaining time of infusion is less than the set value (such as 10 minutes), the alarm will be automatically cut off
