Problems solved by technology

In the dissolution test of the suppositories, in order to accurately test the drug ingredients in the suppository, it is necessary to separate the wax in the suppository. However, the current testing equipment does not have a special device for separating the wax, so the suppository can be directly decomposed. , the accuracy of the test is often not high

Abstract

A suppository testing device, comprising a device main body, a shell and a cover, the device main body includes a bottom column, a base and a diffusion cell column, the diffusion cell column is a half cylinder structure, and the arc surface of the diffusion cell column is From one side to the other side, a first diffusion pool, a second diffusion pool and a third diffusion pool are arranged in sequence, and a plurality of flow holes are arranged on the bottom side wall of the first diffusion pool; the third diffusion pool The top is provided with an outlet; the housing fits around the column of the diffusion pool, and the cover fits inside one side of the housing to achieve detachable connection with the housing. Through the first diffusion pool, The multiple filtration of the second diffusion cell and the third diffusion cell can effectively filter out the wax, which can effectively ensure the accuracy of the drug test inside the third diffusion cell, so that the penetration test of suppository samples can be carried out smoothly.

Description

technical field [0001] The invention belongs to the technical field of application of medical experimental equipment, in particular to a suppository testing device. Background technique [0002] Suppository (Suppository) refers to a solid preparation made of a drug and a suitable matrix with a certain shape for administration in the human cavity. Suppositories are solid at room temperature. After being inserted into the cavity, they can quickly soften and melt or dissolve in secretions at body temperature, and gradually release drugs to produce local or systemic effects. [0003] Since most of the suppositories are condensed into semi-solid by wax, most of the suppositories contain wax components. In the dissolution test of the suppositories, in order to accurately test the pharmaceutical ingredients in the suppository, it is necessary to separate the wax in the suppository. However, the current testing equipment does not have a special device for separating the wax, so the...
