Description

technical field [0001] The invention relates to a medical device, in particular to a device for pulverizing granular medicine, stirring it evenly and then coating it. Background technique [0002] For some medicines, it can be taken internally or applied externally. Some of this medicine are made into tablets during production, which brings troubles for external application. For example, Jidesheng Snake Medicine, a medicine used to treat snake bites, is finished in tablets. When applying externally, it is necessary to grind the tablets with a predetermined amount into powder, then mix with water to form a paste, and apply it on the affected part with a tongue depressor. When grinding, it is difficult to crush the tablets evenly. When mixed with water, if the stirring is insufficient, the ointment will not be uniform, which will affect the adhesion of the medicine to the affected area, and further affect the therapeutic effect of the medicine. In practice, due to the urge...

AI Technical Summary

Problems solved by technology

When grinding, it is difficult to crush the tablets evenly

When mixed with water, if the stirring is insufficient, the ointment will not be uniform, which will affect the adhesion of the drug to the affected area and further affect the therapeutic effect of the drug

In practice, due to the urgent processing time, it is difficult to have enough time to grind and stir, and the drug is easy to fall off after coating on the affected area, which affects the curative effect

In addition, when the pasty drug is applied to the affected area with a tongue depressor, the drug is easy to fall off when it is applied on a large area, and the long-lasting drug effect cannot be guaranteed.
