Study Notes
Biomedical Engineering
- Biomedical engineering is a broad field that involves application of engineering principles to medical devices, systems, and processes.
- Biomedical engineers are expected to have knowledge of medical devices, their design, regulation, and use, as well as safety aspects.
What is Design?
- Design is not research or craftsmanship, but involves the integration of knowledge to accomplish a task.
- Design may require research, and involves devices, processes, re-engineering, systems, optimization, regulations, finances, innovation, and invention.
Design Principles
- Verb: invent, intend, devise
- Noun: drawing, arrangement, pattern, plan, art of making designs
What Might be Designed?
- Optimization of T cell trapping in a microfluidic device
- Biomedical devices (e.g. patient brace, tracking device, hand exerciser)
- Biomedical systems (e.g. patient record-keeping system, vaccine database system)
- Biomedical processes (e.g. patient flow in an emergency room, patient communication in a breast cancer clinic)
Basic but Essential Questions
- Who?
- What?
- Where?
- When?
- Why?
- How?
Design Process
- Generalized flowchart for design process includes:
- What, Who, Where, When, Why
- How
- Go/No-go decision
- National Academy of Science (NAS) design process includes:
- Mission requirements analysis
- Product specification
- Concept development
- Preliminary product and process design
- System prototype development
- Preparation for production
- Production, testing, certification, delivery
- Operation, support, maintenance, disposal
Other Design Concerns
- Retracing if problem is ill defined
- Excessive documentation
- Human patients, animal studies, permissions
- Design is often iterative
- Delving into already patented information bases
- Teamwork, finances, reality
