Steps
Step 1
Application Requirement Analysis
This step conducts in-depth analysis of biomedical engineering problems, clarifying clinical requirements and technical specifications. The core of biomedical engineering is combining engineering technology with medical needs, requiring analysis of physiological mechanisms, technical feasibility and safety requirements starting from clinical application scenarios. Determine design inputs through literature review and clinical needs investigation.
• Search databases such as PubMed and IEEE Xplore, investigate domestic and international research status and technology development trends
• Analyze clinical application scenarios and user needs, clarify indications, target population and key performance indicators
• Identify technical difficulties and risk points, develop technical route and key performance parameter specifications
Deliverable: Requirements analysis report (including literature review, clinical needs, technical specifications, risk analysis, technical route) | Quality standard: Thorough investigation, clear requirements, reasonable specifications, feasible technical route
Step 2
Material Selection and Comparison
This step is an important element in biomedical engineering projects, closely integrating engineering technology with medical needs to solve clinical problems. Biomedical engineering must strictly follow relevant medical device regulations and standards, ensuring safety and effectiveness. Work is carried out using interdisciplinary methods of biology, medicine and engineering.
• Work according to relevant medical device regulations (NMPA, FDA, CE) and standards (ISO, GB, YY)
• Use professional tools (MATLAB/COMSOL/SolidWorks/SPSS, etc.) for design, calculation and data analysis
• Perform biocompatibility and safety evaluation, ensuring compliance with clinical application requirements
Deliverable: Professional report (including method description, experimental data, analysis results, risk assessment, conclusions and suggestions) | Quality standard: Compliant methods, accurate data, safe and effective, compliant with medical ethics
Step 3
Surface Modification Design
This step performs biomedical system or device scheme design, translating clinical needs into specific technical solutions. Biomedical design must simultaneously consider functionality, biocompatibility, safety and regulatory compliance, seeking optimal solutions under multi-objective constraints. Adopt modular design methods to ensure system verifiability, manufacturability and maintainability.
• Perform system architecture design, divide functional modules, determine interface specifications and communication protocols for each module
• Select key components and materials, evaluate biocompatibility according to ISO 10993 or GB/T 16886
• Design circuit schematics or mechanical structures, complete detailed design using Altium Designer or SolidWorks
Deliverable: Design document (including system architecture diagram, schematic/structural diagram, BOM table, material selection description, interface specifications) | Quality standard: Reasonable design, correct parameters, compliant materials, meeting clinical needs
Step 4
Performance Evaluation
This step performs comprehensive performance evaluation and risk assessment of biomedical products, providing basis for clinical application or registration submission. Biomedical evaluation must balance effectiveness, safety and economy, conducting full life cycle risk management according to medical device risk management standards. Form complete evidence chain through pre-clinical evaluation and clinical evaluation.
• Conduct risk management according to ISO 14971, identify hazards, estimate risks, evaluate risks and control risks
• Perform pre-clinical performance evaluation, including summary analysis of bench tests, in vitro tests and animal experiment results
• Compare with similar product performance parameters, analyze technical advantages and clinical value, form comprehensive evaluation conclusion
Deliverable: Evaluation report (including risk analysis, performance assessment, clinical value analysis, comprehensive evaluation, improvement suggestions) | Quality standard: Scientific evaluation method, controllable risks, qualified performance, clear clinical value
