Description

Technical Field

[0001] The utility model relates to the technical field of drug dissolution equipment, in particular to a dissolution instrument sample feeding device. Background Art

[0002] Drug solubility is an important indicator of drug quality control. The absorption rate of drugs in the body is often determined by the speed of dissolution. Before being absorbed, drugs in solid preparations must undergo a process of disintegration and dissolution and then be converted into solutions. If the drug is not easy to release from the preparation or the dissolution rate of the drug is extremely slow, there may be problems with the absorption rate or degree of the drug in the preparation. Therefore, measuring the dissolution rate of drugs is a key step for pharmaceutical companies when developing drugs. When performing drug dissolution tests, drug samples need to be put into dissolution cups. The traditional manual dosing method requires the experimenter to manually put the tablets into the dissolution cups one by one at a certain time interval and time them separately. This drug sample dosing method has a dosing time difference. In the case of batch testing of samples, it is difficult to ensure that the dissolution time of drug samples in each dissolution cup is consistent, resulting in large differences in the dissolution results between drug samples in different dissolution cups. Therefore, a dissolution instrument sampling device is proposed to facilitate the simultaneous placement of multiple samples. Utility Model Content
