Study Notes
Introduction to Biomedical Devices
- Medical instruments leverage specific physiological properties to evaluate health conditions.
- Initial design phase emphasizes understanding the underlying concepts of health assessment.
- The subsequent phase focuses on defining requirements ensuring safety and efficacy of medical products.
Levels of Technology in Healthcare
- Level 0: Diagnosis and therapy are manual and unassisted by technology.
- Level 1: Technology aids diagnosis by providing clinically relevant parameters to support pathology detection.
- Medical devices (MD) encompass instruments or materials intended for human use, including necessary software.
Categories of Medical Devices
- Diagnostic Equipment: Information flows from the patient to the technology for health assessment.
- Therapeutic Equipment: Delivers treatment to the patient, including rehabilitation devices.
- Information Processing Systems: Analyzes gathered information to aid clinical decision-making.
Tasks in Diagnostic Equipment
- Sense patient information and convert it into electrical signals.
- Eliminate artifacts and irrelevant information from the signals.
- Extract meaningful physiological parameters to assist clinician interpretation.
Importance of User-Centric Design
- Medical instrumentation must account for user involvement, particularly the 'doctor–patient in the loop'.
- Innovative products should focus on actual healthcare needs and be designed for ease of use by doctors, technicians, and patients.
Medical Instrumentation Approach
- Define medically relevant problems and metrics to measure them.
- Select appropriate instruments to detect said problems.
- Consider the organization of healthcare services to incorporate user interaction effectively.
Dimensionality of Measured Variables
- Point parameters (e.g., blood pH).
- 1-D waveforms: Changes over time or space (e.g., EEG).
- 2-D waveforms: Spatial or temporal changes (e.g., X-ray images).
- 3-D waveforms: Represent variables in three-dimensional space (e.g., CT scans).
- 4-D waveforms: Depict variable behavior over time in three dimensions (e.g., cardiac MRI).
Noise and Artifacts in Data
- Measured variables may be impacted by noise and artifacts.
- Hardware and software tools are essential to represent data accurately, assisting clinicians in determining pathologies and their severity.
Requirement Management
- The design team must outline system performance requirements and expectations to ensure functional effectiveness.
