The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] For some patients with swallowing disorders, such as those with oral and throat diseases or neurological diseases that affect swallowing, ground medicines are easier to swallow. For example, stroke patients may have decreased swallowing muscle control ability. Grinding the tablets into powder can make it easier for them to take the medicine. Ordinary tablets for the treatment of high blood pressure can be better accepted by such patients after being ground into powder, avoiding resistance to taking medicine due to swallowing difficulties. Some drugs themselves taste bitter. After grinding, they can be mixed with some sweet foods or liquids to improve the taste. In traditional nursing departments, nurses are required to manually crush and grind the tablets, which makes the processing efficiency low.
