Detailed Description

The infusion alarm device is composed of a liquid drop detection module, a liquid level detection module, a signal processing module, a data acquisition card, a Labview development platform, a controller, an infusion locking module and an audible and visual alarm module. The liquid drop detection module comprises a photosensitive sensor; the photosensitive sensor uses infrared rays for monitoring and converting into optical signals and electric signals. The liquid level detection module comprises a float type liquid level sensor; float level sensors utilize a tiny metal film strain sensing technique to measure the level of a liquid.

The input end of the signal processing module is connected with the liquid drop detection module and the liquid level detection module, and the output end of the signal processing module is connected with the data acquisition card; and the data acquisition card is connected with the Labview development platform. The signal processing module comprises a filter circuit, an amplifying circuit and a converting circuit, wherein the filter circuit filters and denoises information acquired by the photosensitive sensor, the information is amplified by the amplifying circuit, and the converting circuit converts the information into a digital signal and uploads the digital signal to the data acquisition card and the Labview development platform; the input end of the controller is connected with the Labview development platform, and the output end of the controller is connected with the infusion locking module and the audible and visual alarm module. And the Labview development platform compares the analysis result of the uploaded data with preset parameters and then transmits the analysis result to the controller. The controller sends an alarm to the sound-light alarm module according to the signals collected by the data collection card and adjusts the sound-light alarm module through the transfusion locking module.

When the infusion alarm device works, firstly, a liquid drop detection module and a liquid level detection module are correspondingly arranged on a dropper of an infusion bottle and a bottle body of the infusion bottle, when the infusion alarm device works, the infusion alarm device is initialized, in the working process, the liquid drop detection module and the liquid level detection module carry out signal acquisition through sensors, the acquired signals are uploaded to a signal processing module, and the signal processing module converts the signals into digital signals through a conversion circuit and uploads a data acquisition card and a Labview development platform; the Labview development platform compares the analysis result of the uploaded data with preset parameters and then transmits the comparison result to the controller, and if the comparison value is smaller than or reaches a set value, the controller sends an instruction to the infusion locking module and the acousto-optic alarm module to make the infusion locking module give an audible alarm and clamp the dropper; otherwise, the alarm and the dropper are cancelled to ensure the normal operation of the dropper.
