Improvement of instrument for preparation of medical patch material / 医疗卫生装备

ABSTRACT

Objective To modify the existing preparation instrument for medical patch material to realize its scale and automatic production.Methods The instrument had its shaking table improved and a cylindrical processing system added with comprehensive analysis on raw materials and kinds of process flows.A spreading and fixation mechanism for animal materials was placed in the cylindrical processing system,which had the holes for liquid inlet and outlet respectively on its top and bottom.The cylindrical processing system was fixed to the base of the shaking table.Results The instrument enhanced preparation efficiency significantly,and had the raw material utilization rate increased by 20％,product qualification rate raised by 35％,preparation cycle reduced by 33％ and total cost saved by 40％.Conclusion The instrument behaves well in adaptability to multi animals,preparation process,inter-assay difference,raw material utilization rate,product qualification rate and cost reduction,which is of great significance to promote the clinical application of medical biological patch.
