Abstract
Description
Technical Field

[0002] Gels refer to thick liquid or semi-solid preparations in the form of solutions, suspensions or emulsions made of drugs and excipients that can form gels. During the preparation process of gels, it is necessary to ensure that the colloidal particles are evenly dispersed, do not sink or clump, and remain in a gel state at room temperature. The existing operation generally involves adding raw materials, excipients and solvents into a stirring device for stirring. However, most raw materials and excipients are in powder form, and the contact area with the solvent is limited, which can easily cause uneven stirring and mixing. At the same time, since the gel is in a gel state, it is easy to adhere to the side wall of the gel container, and the gel attached to the container wall is easy to coagulate into lumps because it cannot be fully stirred, resulting in long-term attachment to the container. It is difficult to pour out and is not easy to clean, resulting in waste of gel. This affects the quality of the finished gel product and ultimately affects the effect of the gel.
