Device Classification Workflow
器械分类流程
Classify device under MDR Annex VIII:
- Identify device duration (transient, short-term, long-term)
- Determine invasiveness level (non-invasive, body orifice, surgical)
- Assess body system contact (CNS, cardiac, other)
- Check if active device (energy dependent)
- Apply classification rules 1-22
- For software, apply MDCG 2019-11 algorithm
- Document classification rationale
- Validation: Classification confirmed with Notified Body
依据MDR附件VIII对器械进行分类:
- 确定器械使用时长(短暂、短期、长期)
- 判定侵入性等级(非侵入式、体腔接触、手术侵入)
- 评估接触的身体系统(CNS、心脏、其他)
- 检查是否为有源器械(依赖能源)
- 应用分类规则1-22
- 针对软件,应用MDCG 2019-11算法
- 记录分类依据
- 验证: 分类结果经公告机构确认
