一覽

IEC 62304 is the international standard for medical device software development, encompassing risk management, design controls, traceability, testing, and post-market surveillance. Used in hospitals, clinics, and every FDA-regulated medical device. Mastery takes 8-12 months. IEC 62304 expertise commands 25-35% premium because regulatory violations = lawsuits, recalls, and criminal liability. Non-compliance can halt device commercialization. Essential for medical device manufacturers, healthcare IT, software engineers in regulated industries, and quality assurance roles.

什麼是 IEC 62304 Medical Software

IEC 62304 is the international standard for medical device software lifecycle processes. It mandates planning, design controls, risk management, traceability, testing, validation, and post-market surveillance. The standard ensures medical device software is safe, effective, and traceable from requirement to deployment. Practitioners apply IEC 62304 across the full development lifecycle: risk analysis (what can go wrong?), design specification (how will it work?), code review (are requirements met?), testing (does it work?), and validation (does it work in the real world?). Every step is documented, traced, and auditable for FDA or European regulatory inspections.

❓ 常見問題

What's the difference between IEC 62304 Class A, B, and C software?
Class A (low risk): no injury if it fails (e.g., scheduling app). Class B (medium risk): serious injury possible (e.g., drug dosage calculator). Class C (high risk): death/permanent harm (e.g., pacemaker firmware, surgical robot). Higher class = more documentation, more testing, more oversight. Classification drives effort. Class C = 2-3x more work than Class B.
What's V&V (Verification & Validation) in medical device context?
Verification: Did we build it right? (does software match spec). Validation: Did we build the right thing? (does software meet user needs). Both required by IEC 62304. Verification = unit tests, integration tests, code review. Validation = user acceptance testing, real-world scenarios. Both must be documented, traceable.
What's traceability and why is it critical?
Traceability = every requirement → design → code → test → validation documented and linked. Audit trail showing requirement X is implemented in file Y, tested by test Z. If bug found, trace back to root cause. Missing traceability = failed audit. Tools: Jira, Azure DevOps with traceability plugins. Overhead: 20-30% of development effort.
What's 21 CFR Part 11 and how does it apply?
21 CFR Part 11 = FDA regulation for electronic records, electronic signatures. If your medical software handles patient data or submissions, Part 11 applies. Requirements: audit trails, access control, data integrity, secure deletion. Compliance demonstrates record integrity to FDA. Missing Part 11 = rejected submission.
What's the 510(k) pre-market notification and how does software documentation fit?
510(k) = FDA pathway for 'substantially equivalent' medical devices. Submit if device similar to existing cleared device. Requires software documentation: design spec, risk analysis, validation summary, test results. Software documentation 20-40% of 510(k) submission. Clearance time: 30-90 days. IEC 62304 documentation streamlines 510(k) preparation.
