Description

Technical Field

[0001] The utility model relates to the field of grinding equipment, in particular to a grinding device for piperacillin sodium and tazobactam sodium medicine powder for injection. Background Art

[0002] Piperacillin Sodium and Tazobactam Sodium for Injection, the indication is piperacillin / tazobactam is suitable for the treatment of the following systemic and / or local bacterial infections caused by detected or suspected sensitive bacteria. In the pharmaceutical process, grinding and mixing drugs is a common pharmaceutical method. Traditional drug grinding and mixing requires manual work, which is time-consuming and labor-intensive, and has low yield. The existing grinding and mixing equipment does not grind the drugs thoroughly enough, and the ground and mixed drugs are not easy to collect, which reduces the work efficiency of the staff. Among them, a pharmaceutical mixing equipment with application number "CN201710456273.0" uses grinding balls to grind materials and uses a dividing plate to separate materials. Pre-mixing is carried out, and at the same time, the material is prevented from falling directly into the bottom of the grinding box and affecting the grinding effect. The material at the bottom of the inner side of the grinding box is turned over by using a panel to make the material at the bottom of the inner side of the grinding box more fully ground and improve the grinding effect. The material is stirred and mixed by using a stirring blade. By setting a handle, it is convenient for the staff to pull the collection cabinet out of the mixing box, thereby improving work efficiency. However, there are still certain deficiencies in the use of this equipment: the distance between the grinding ball and the grinding box is large, which makes the ground particles larger. For the grinding of piperacillin sodium and tazobactam sodium injection powder, the powder particle requirements are relatively high, and the grinding requirements of this equipment cannot meet the powder grinding requirements.
