Very interesting and relevant lecture by Ian Hewitt entitled “Design for Medical and Well Being”

Ian discussed one of the most important considerations when designing medical products which is standards and classifications which are determined by Implant, intrusive and data recording.

There are 3 classes:

Class 1

  • Low risk .. e.g. walking stick, wheel chair

Class 2

  • Stringent Regulations
  • Record data, Limited diagnosis
  • E.g. Syringe, gloves, pregnancy Kit- self diagnostic

Class 3

  • Highest category
  • High Risk- complex devices
  • Pace Maker, Ocular tweezers, Insulin Pen, Cannula.

  • NHS may not likely adopt your project just due to the system , pricing range, competitors …  “disruptive innovation”

  • Colours

Data recording

  • Legality with holding data
  • Has to be stored in a certain way


  • Safety
  • Delivery of Information

  • Paint
  • Material type (Allergies)
  • Finishes

End User

Consider constructing DARL and CRL logs as method for development

An incredibly relevant and useful lecture and I have discussed to have a meeting with Ian in the upcoming weeks to gain his thoughts and views on the project.
