Abstract

The invention discloses an absorption cell structure of a medicine absorption sampling system. The absorption cell structure is characterized in that a permeation film is arranged at the center of theabsorption cell, a mother liquor cavity is formed on one side of the permeation film, and an absorption cavity is formed on the other side of the permeation film; a mother liquor outlet is formed inthe top of the mother liquor cavity, and a mother liquor inlet is formed in the bottom of the mother liquor cavity; a drainage hole is formed in the top of the absorption cavity, and a solvent entrance is formed in one side of the bottom of the absorption cavity. Via the magnetic effect, the stirrer is driven to rotate, so that the stirrer is rotated in the absorption cavity to simulate the bloodflowing in a human body, the experiment is facilitated, and the use effect is good.

Description

technical field [0001] The invention belongs to the technical field of medical experiment equipment application, in particular to an absorption pool structure of a drug absorption sampling system. Background technique [0002] Oral preparations are a common dosage form. The premise for oral drugs to exert their medicinal effects is that the drugs are released, absorbed by the gastrointestinal tract and enter the body to exert pharmacological effects (except for drugs that directly act in the gastrointestinal tract). Evaluation of drug release and absorption is Very important content of oral preparations. In order to simulate the release and absorption of drugs in the gastrointestinal tract (eg, intestinal tract), some biomimetic systems have been developed in the prior art. For example, the Chinese invention patent No. 201110280230.4 provides a drug absorption instrument. The structure of the absorption pool of this type of absorption instrument is simple, which cannot wel...
