Automatic liquid medicine mixing method

Abstract

The invention discloses an automatic liquid medicine mixing method. The method involves a liquid medicine preparation device, and the device comprises a PLC, a three-dimensional motion machine provided with a mechanical claw, a mother liquor workbench for storing a plurality of mother liquor bottles, injectors, a metering workbench for storing sample cups and a rack; and a weight sensor for metering is arranged below the sample cups, the bottlenecks of the mother liquor bottles are screwed with the injectors, each injector comprises an injector body and a piston, the mechanical claw comprisesa clamping and rotating mechanism, and the clamping and rotating mechanism is used for clamping and rotating the injector bodies and extracting the pistons. The working process of the device mainly comprises four steps of calling out, extracting, injecting and sending back, the movement of the injectors between the mother liquor bottles and the sample cups is realized by the aid of the mechanicalclaw in different preparation processes, and the process is mainly set by the PLC. The method and the device can replace manual operation to increase the working efficiency, reduce the labor intensityand ensure smooth development of research work, and are suitable for various medical and chemical enterprises.

Problems solved by technology

Especially in the teaching and scientific research work in the chemical industry, laboratories, research rooms, etc., will use a large number of chemical reagents. High precision, but also limited by various conditions such as orderliness and timeliness

Reagent configuration is a very cumbersome and time-consuming work, especially for research reagent configuration and formula, which often requires many configuration tests. When there are a large number of reagents (dozens of types), manual operation and record Time-consuming and labor-intensive, it is necessary to search a large number of reagent bottles, which has problems such as heavy tasks and low efficiency; laboratory managers cannot conveniently and quickly check the remaining amount of chemical reagents, and if they are not replenished in time, the progress of experimental research will be affected

At present, similar products are mostly used in medical and chemical companies, and are usually expensive or have a single configuration

The configuration of chemical reagents on the laboratory site is still limited to manual operation. If a small-scale, decentralized drug configuration system is to be constructed to achieve multi-type configurations, there is still a lack of standardized construction standards and operating modes. At the same time, the corresponding environmental purification costs and hardware The maintenance cost has not been significantly reduced, which has affected the progress of experiments in many institutions
