A kind of preparation method of powder medicament for pharmacy department

Abstract

The invention belongs to the technical field of medical treatment, and particularly relates to a powder medicament manufacturing method for the pharmacy department. The powder medicament manufacturingmethod adopts grinding equipment. The grinding equipment comprises a grinding barrel, a connecting frame, a push handle and a conveying unit. The grinding barrel is in a cover-less cylinder shape. The connecting frame is vertically connected into the barrel wall of the grinding barrel. A grinding protrusion and a spiral groove are formed in the inner side barrel wall of the grinding barrel. The push handle is arranged on the right side of the exterior of the grinding barrel. The conveying unit is used for conveying tablets to the left side of the interior of the grinding barrel for grinding,the tablets are placed into the grinding barrel from a feeding hole, and then tablet raw materials are pushed to the left side of the grinding barrel through the push handle and the conveying unit. The tablet raw materials are fully crushed and ground through the grinding protrusion on the left side inner wall of the grinding barrel. Powder formed after grinding flows out from the left end of thegrinding barrel. The grinding equipment adopted by a grinding method is simple in structure and low in cost, the tablets are fully extruded and ground through the grinding protrusion and a pushing block of a material passing hole in the grinding barrel, the operation steps are simple, and the grinding efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the field of medical treatment, and in particular relates to a preparation method of powder medicine used in pharmacy. Background technique [0002] Tablet medicine is one of the most common oral preparations. People usually take it directly with water, but when encountering some comatose or unconscious patients, they need to be ground into powder according to the dosage requirements of the medicine. [0003] At present, most of the methods of grinding tablet drugs are to use ceramic medicine pestle on the market. The ceramic medicine pestle is composed of a pounding medicine cylinder and a medicine hammer. This grinding method requires the staff to manually operate the medicine hammer, and the sound is loud when smashing medicine, especially in night shifts. When the nurse uses it, it will affect the rest of the patient, and it is easy to be damaged after repeated use; the tablet is ground manually, and the tablet is not broke...

[0003] At present, most of the methods of grinding tablet drugs are to use ceramic medicine pestle on the market. The ceramic medicine pestle is composed of a pounding medicine cylinder and a medicine hammer. This grinding method requires the staff to manually operate the medicine hammer, and the sound is loud when smashing medicine, especially in night shifts. When the nurse uses it, it will affect the rest of the patient, and it is easy to be damaged after repeated use; the tablet is ground manually, and the tablet is not broken enough, so that the drug powder is doped with some larger particles, which is not conducive to the absorption of the patient, which is time-consuming, laborious and inefficient. Extremely low; at the same time, for some tablets with high hardness, it is impossible to obtain powder by manual grinding
