Dissolving cup cover opening mechanism of automatic release rate sampling system

Abstract

The invention provides a dissolving cup cover opening mechanism of an automatic release rate sampling system. The dissolving cup cover opening mechanism comprises a transverse plate, a dissolving cupholder fixing block, a dissolving cup holder, a rotating block, a dissolving cup cover, a shifting block fixing plate, a shifting block, a limiting rod and a rebounding device, wherein the dissolvingcup holder fixing block is arranged on the upper surface of the transverse plate; the rotating block is arranged on one side of the dissolving cup holder fixing block; the dissolving cup cover comprises a cover plate and a rotating plate, and two side edges of the cover plate are of a downward-turning structure to form a cover plate turning edge, wherein one end of the rotating plate is turned upwards to form a rotating plate handle, and the other end of the rotating plate is turned downwards to form a rotating plate turning edge; the center of the shifting block is rotatably connected to theshifting block fixing plate through a shaft; one side surface of the shifting block is provided with a shifting block cross rod; the limiting rod is arranged on one side of the top end of the shiftingblock; and the rebounding device is arranged on one side of the dissolving cup cover and comprises a rebounding device shell, a rebounding rod, a rebounding rod lug, a rebounding rod resisting pieceand a spring. The dissolving cup cover realizes automatic cover opening and closing, and has high continuity and high test efficiency in the instrument test process; and the structure is simple, the manufacturing process is simple, the production cost is low, and the economic performance is high.

Description

technical field [0001] The invention belongs to the technical field of medical experiment equipment application, in particular to a melting cup cover opening mechanism of an automatic release rate sampling system. Background technique [0002] In order to simulate the absorption status of drugs in the gastrointestinal environment and detect the dissolution rate of different drugs, a dissolution apparatus has been proposed in the field of medicine to detect various key indicators such as the dissolution rate of drugs. The dissolution apparatus is to place the drug in the medicine basket, extend it into the dissolution cup through the lifting mechanism, and rotate the cradle in the dissolution cup through the rotating device to perform the drug release experiment. After improving the dissolution apparatus, the rotation device of the dissolution apparatus was improved to a device that moves up and down, and other structures were improved, and a new type of automatic release rat...

AI Technical Summary

Problems solved by technology

The existing technology has the following technical defects: During the test, it is necessary to repeatedly open and close the lids of each set of dissolving cups. In this process, the existing testers manually perform repeated operations, which makes the test process cumbersome and affects the test. The continuity of the process reduces the test efficiency. In the current technology, there is no structure in the release rate sampling system to automatically open the lid of the dissolution cup.
