Mike MacLean Opioid Devices

Accomplishments

  • Created wristwatch enclosure v1
    • Alan is very useful and enthusiastic. I gave him some guidance on how to go about the process and he made modifications to an existing enclosure design independently and in a timely manner.
  • Created inductor watch v1 – can be used as bracelet.
  • Measured time-to-release of existing device and new device with stainless steel washer. It’s not the right size but we see heating improvements with the new, magnetic stainless steel.

  • Explored device fabrication with 430 stainless steel – a biocompatible and highly magnetic steel.
    • Reached out to multiple companies
    • Reached out to Norvin to see if we can just make our own to the exact dimensions we want.
  • Barriers
    • We’ve been using non-magnetic steel.
    • Release times are still slow, even with the washer. I still cannot get the drug to release in a reasonable time without forcing the device inside the coil.
The needle we use – 304 stainless steel
304 stainless steel is only sightly magnetic

This week

  • Solder and test new board design
  • Create enclosure for new board design
  • Get all three LED’s working synchronously and design algorithm to extract oxyhemoglobin and deoxyhemoglobin concentrations.
  • How to proceed with powering? I think simulations or redesign are in order.
