Fluid sampling device for drug analysis

Abstract

The invention discloses a fluid sampling device for drug analysis. The fluid sampling device comprises a sampling barrel, the bottom of the sampling barrel is communicated with a sampling needle tube;two air outlets for adjusting air pressure are formed in the top of the sampling barrel; an isolation sleeve plate is fixed in the sampling barrel; the sampling barrel is divided into two cavities through the isolation sleeve plate; a multi-bottle sampling device for multi-bottle quantitative sampling for drug analysis is mounted on the sampling barrel; the first piston rod in the multi-bottle sampling device stretches out and draws back to realize sampling of drugs, the quantitative adjusting piece and the flow dividing assembly are matched with each other so that equivalent medicine samplesare titrated in a plurality of test tubes at a time, compared with an existing mode that personnel titrate the medicine samples in the test tubes one by one, the titration speed is high, the titration amount of a solution in each test tube does not need to be measured, and a large amount of time is saved.

Description

technical field [0001] The invention relates to the technical field of drug analysis and sampling, in particular to a fluid sampling device for drug analysis. Background technique [0002] Drug analysis is the use of chemical, physical, biological and microbiological methods and techniques to study the chemical testing of drugs, drug stability, bioavailability, drug clinical monitoring, and the qualitative and quantitative analysis of active ingredients in Chinese herbal medicines. a discipline. It includes chemical inspection of finished drug products, quality control of drug production process, quality inspection of drug storage process, clinical drug analysis, in vivo drug analysis, etc. [0003] When analyzing raw materials, targeted sampling is required. Usually, personnel take tools to sample drugs and then analyze them. Existing fluid drugs usually use sampling tubes or plastic droppers to absorb drugs, and then drip Into the test tube, when the current fluid sampli...

Problems solved by technology

[0003]When analyzing raw materials, targeted sampling is required. Usually, personnel take tools to sample drugs and then analyze them. Existing fluid drugs are usually It is to use a sampling tube or a rubber dropper to absorb the drug, and then drop it into the test tube. When the fluid is sampled, the extraction amount is controlled by personnel observing the scale on the test tube bottle. There are observation errors, resulting in multiple The amount of sampling between samples is prone to deviation, and each sampling can only take one bottle. When there are many detection and analysis items, it is impossible to take a large number of samples in a short time, resulting in low efficiency. Therefore, we propose a drug analysis Fluid Sampling Devices
