Tablet cutting device
Technical Field
The invention relates to the technical field of medical instruments, in particular to a tablet cutting device.
Background
In general, a pharmacist or a pharmacist in a hospital dispenses a medicine in a dosage smaller than one tablet, and in this case, the tablet needs to be divided into two equal parts or other equal parts according to the medication condition and then dispensed. The general tablet is round or oval in shape, and although the general tablet is provided with streaks for facilitating medicine distribution, patients in hospitals are more, the dosage is larger, different patients have different illness states, and the dosage of medicines is different. It is often encountered that the dosage is one third of that of a tablet, and that it is necessary to make three equal parts of the tablet, but typically tablets are provided with only two equal parts of the striation. At this time, it is necessary to use a drug cutting tool for three equal parts. The conventional medicine cutting tools are basically single type medicine cutting tools, such as two-part medicine cutting tools and three-part medicine cutting tools, and the medicine cutting tools need to be replaced continuously when a medicine dispenser uses the medicine cutting tools, so that the medicine cutting work efficiency is seriously affected.
