Method and device for monitoring preparation of mixed medicament

Abstract

The invention relates to a method and device for monitoring preparation of a mixed medicament. The method comprises the following steps: acquiring a first accumulative flow of a first prepared solution and a second accumulative flow of a second prepared solution every preset time; calculating the current first flow of the first prepared solution according to the first accumulated flow obtained in the current preset time and the previous preset time; and when the current first flow is inconsistent with the first flow obtained in the previous preset time, calculating a first residual volume of the first prepared solution, a second residual volume of the second prepared solution and a second proportion of the first residual volume and the second residual volume, determining a second flow corresponding to the second prepared solution according to the current first flow and the second proportion, and controlling the flow of the second prepared solution to be changed into the second flow. The solution preparation flow can be monitored and adjusted in real time, it is guaranteed that the mixed medicament prepared in each time period meets the proportion requirement, and the reliability of preparation of the mixed medicament is effectively improved.

Description

technical field [0001] The present application relates to the technical field of medicament preparation monitoring, in particular to a method and device for monitoring the preparation of mixed medicaments. Background technique [0002] The preparation of mixed medicaments is to mix more than two kinds of preparations that need to be mixed according to the ratio requirements; the main method of preparation of mixed medicaments at present is to set the initial flow rate of each preparation, and the ratio between the initial flow rates of each preparation is equal to that of the mixed preparations. According to the proportion requirements, when the preparation starts, each dosing liquid enters the mixing tank at the initial flow rate for real-time preparation, and the mixed medicine that meets the proportion requirements is obtained. [0003] During the preparation of the above-mentioned mixed medicament, due to the change of gravitational potential energy or other emergencies ...

AI Technical Summary

Problems solved by technology

[0003] During the preparation of the above-mentioned mixed medicament, due to the change of gravitational potential energy or other emergencies that affect the flow of the dosing liquid, it cannot be guaranteed that each dosing liquid will always enter the mixing medicine box at the initial flow rate, so that the ratio of the prepared mixed medicament Inconsistent with the ratio requirements, especially when the flow of one or more of the dosing liquids cannot be accurately controlled, the error will be greater, resulting in the unusable mixed medicament, resulting in a waste of resources
