基于新版《医疗器械分类目录》的医疗器械分类编码解析与查询机制研究

Research on medical device classification code analysis and inquiry mechanism based on the new version of Medical Device Classification Catalogue

目的:基于国家药品监督管理局2017年发布的新版《医疗器械分类目录》,提出一种简单易行的编码规则,设计新版《医疗器械分类目录》查询系统,实现医疗器械分类信息的快速查询。方法:在新版《医疗器械分类目录》基础上,提出采用WS/T18-1999"68"编码方式,将编码拓展至第四级,将医用装备和耗材编码加以区分,并预留缺省代码的医疗器械分类编码方式;使用Excel2007建立医疗器械分类关联结构数据库,采用可视化开发工具(VS)结合视觉基础应用程序(VBA)设计新版《医疗器械分类目录》查询系统。选取医院在用医用装备麻醉机和医用耗材气管插管为研究对象对其进行分类与编码,解析其分类编码过程。结果:查询系统可提供医疗器械编码、医疗器械品名和医疗器械预期用途3种递进式模糊查询,使用一级检索结构浏览查询结果,二级结构显示规范的《医疗器械分类目录》管理信息。结论:基于新版《医疗器械分类目录》的医疗器械分类编码解析与查询机制可在一定程度上提高操作者工作效率,降低因认知不足而造成的错检和漏检。

Objective:To proposed a simple and easy coding rules based on the new version of Medical Device Classification Catalogue and design a new version of the inquiry system for the Medical Device Classification Catalogue to realize fast inquiry of the classification information of medical devices.Methods:On the basis of the new version of Medical Device Classification Catalogue,the coding method was proposed to adopt the WS/T18-1999"68"coding method,extend the coding to the fourth level,distinguish the coding of medical equipment and consumables and reserve a default code for the classification of medical devices.The associated structure database of medical device classification was established in Excel 2007,and an inquiry system for the new version of Medical Device Classification Catalogue was designed by using the visual studio(VS)in combination with the visual basic for applications(VBA).Results:The inquiry system can provide three types of progressive fuzzy query,namely,the medical device code,the medical device name and the intended use of the medical device.The primary retrieval structure was used to browse the search results,and the secondary structure was used to display the standard administration information under the Medical Device Classification Catalogue.Conclusion:The medical device classification code analysis and inquiry mechanism based on the new version of Medical Device Classification Catalogue can,to a certain extent,improve the working efficiency of operators and reduce the misdetection and omission caused by cognition deficiency.
