A drug dissolution tester

Abstract

The invention discloses a test instrument for dissolution rate of drugs and mainly relates to the technical field of drug inspection. The test instrument comprises a base, wherein four adjusting bolts are arranged at the edge of the base; a reference block is arranged on the base; a level bubble is arranged on the reference block; a cylindrical lug boss and a heating box are arranged at the top of the base; an annular water bath box is arranged on the cylindrical lug boss in a sleeving manner; an annular cover is arranged at the top of the annular water bath box; a lifting mechanism is arranged on the cylindrical lug boss; a cylindrical shell is arranged at the top of the lifting mechanism; a driving motor is arranged at the top of the cylindrical shell; a plurality of rotating shafts are annularly arrayed on the cylindrical shell; stirring paddles are arranged at the bottom of the rotating shafts; a dissolving cup is arranged in the annular water bath box. The test instrument has the beneficial effects of reducing the interference factor of the dissolution rate test, guaranteeing the reliability of the test result, shortening the time for correcting the test instrument for dissolution rate and improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of drug testing, in particular to a drug dissolution tester. Background technique [0002] Dissolution rate refers to the speed and degree of drug dissolution from solid preparations such as tablets in a specified solvent. Dissolution rate is an important indicator of tablet quality control. At present, the dissolution tester is mostly used to test the dissolution rate of drugs. The test results of the dissolution tester are easily affected by many factors. If the instrument is not placed horizontally and the verticality of the rotating shaft is too large, the dissolution rate will increase (relevant records are recorded in the sixth issue of volume 25 of "Northwest Pharmaceutical Impurities" in December 2010). In order to solve this kind of interference, it is necessary to , the dissolution tester is calibrated with a level, a square, etc. The calibration process takes up a lot of time and the work efficie...

Problems solved by technology

At present, the dissolution tester is mostly used to test the dissolution rate of drugs. The test results of the dissolution tester are easily affected by many factors. If the instrument is not placed horizontally and the verticality of the rotating shaft is too large, the dissolution rate will increase (relevant records are recorded in the sixth issue of volume 25 of "Northwest Pharmaceutical Impurities" in December 2010). In order to solve this kind of interference, it is necessary to , the dissolution tester is calibrated with a level, a square, etc. The calibration process takes up a lot of time and the work efficiency is low, and the water bath of the existing dissolution tester is heated by a heating wire installed at the bottom, and the heating wire is long. Scale will be generated on the surface during time use (application number: 201420243202.4, patent name: an improved dissolution test device), which will easily cause differences in water temperature at different positions in the water bath tank, thereby affecting the detection results of the dissolution tester
