Abstract

The invention provides a high-efficiency drug dissolution tester which comprises a head and an engine base, wherein the head is fixed above the unit in a lifting manner by virtue of a hydraulic cylinder; a water bath is arranged in the engine base; dissolution cups are arranged in the water bath in a matrix manner; a two-area synchronous speed regulation mechanism is arranged on the head; the two-area synchronous speed regulation mechanism comprises an upper supporting plate arranged in the head; two synchronous speed regulation assemblies are arranged on the upper supporting plate; each synchronous speed regulation assembly comprises six stirring mechanisms; each stirring mechanism corresponds to one dissolution cup; each stirring mechanism comprises a fixing seat; a stirring shaft is arranged on the fixing seat in an inserted manner; a synchronizing shaft is arranged on the top of each fixing seat; and a first synchronous pulley is arranged on each synchronizing shaft. According to the high-efficiency drug dissolution tester disclosed by the invention, the rotation speeds can be respectively fixed in separate areas, the rotation speed in each area can be independently set, the working efficiency is improved, and experimental errors are reduced; and meanwhile, the dosing mechanism is improved, and the experimental accuracy is further improved.

Description

technical field [0001] The invention relates to a dissolution apparatus, in particular to an efficient medicine dissolution apparatus. Background technique [0002] The drug dissolution apparatus is an instrument for drug dissolution experiments. It is a mechatronics test equipment controlled by a microcomputer, and each component is centrally controlled by a precision control system. The drug dissolution test is a test method for the dissolution rate and dissolution rate of solid pharmaceutical preparations such as tablets, capsules, and granules under certain conditions. Bioequivalence and bioavailability are also important indicators for evaluating the quality of drugs before clinical use. [0003] Patent 201720601696.2 discloses a drug dissolution apparatus for ibuprofen soft capsules. The drug dissolution apparatus for ibuprofen soft capsules includes a machine head and a machine base; a built-in control system in the machine head; a water bath box is arranged on the ...
