Circular tablet reducing mechanism is used to oncology
Technical Field
The invention relates to the field of oncology, in particular to a circular tablet crushing device for oncology.
Background
The tumor is a new organism formed by local tissue cell proliferation under the action of various tumorigenic factors, and is divided into two main types of benign tumor and malignant tumor according to the cell characteristics and the harmfulness degree of the new organism. Malignant tumors can be classified into carcinomas and sarcomas, and carcinomas refer to malignant tumors derived from epithelial tissues.
Tumor treatment needs to be constantly taken to inhibit tumor diffusion, but when the tumor is gradually diffused seriously, the eating ability of a patient is gradually reduced, so that the patient can not swallow tablets normally, and the tablets need to be crushed.
