Problems solved by technology

[0002] In the medical field, during drug development and proportioning, it is necessary to grind the drug into a fine powder, and then press the drug into a tablet, which is convenient for patients to take quantitatively; in the process of drug grinding, a grinder is needed, and the traditional grinding The bottom of the device is concave in a rounded arc shape, the drug is concentrated at the bottom of the grinder, and the grinding rod can be easily squeezed and ground; since the radius of curvature of the grinding rod is inconsistent with the radius of curvature of the inner bottom of the grinder, the grinding process is like two An inscribed spherical surface can only achieve point contact, and the grinding efficiency is greatly reduced at this time; in addition, when encountering drugs with hard particles, the drug particles are easy to collapse during the extrusion process between the grinding rod and the grinder, which not only affects the grinding effect , affect the progress of the experiment, and cause waste of drugs

Abstract

The invention relates to a working method of a solid drug grinder. The solid drug grinder comprises a grinding disc and a grinding rod; the grinding rod comprises a handle and a grinding ball mountedat the position of the handle; the outside of the grinding ball is coated with an elastic layer, and a spherical space is filled with regulation liquid; a regulation barrel is arranged in the handle,and the regulation barrel is communicated with the spherical space by a deflector hole; a piston plate is arranged in the regulation barrel, and the piston plate can slide in an air-tight reciprocating mode on the barrel wall of the regulation barrel; a regulation ring is also arranged on the handle, a regulation screw is fixedly arranged on the axis of the regulation ring, and the regulation screw passes through the axis of the piston plate; grinding sheets are tightly arranged in an array mode on the outer surface of the elastic layer, and the section of each grinding sheet is of a sector shape; the grinder is novel in structure; a grinding speed can be effectively improved; a grinding effect can be reinforced; drug splashing is effectively prevented; efficient and safe preparation of drugs is implemented.
