Medical Device Validation Stencil
Unfortunately, since the Fixture is still in production, I cannot share the Solidworks drawings or validation testing data due to an NDA... BUT I can show the initial prototype, and I can demonstrate how it works!
​
This process was incredibly fulfilling. It occurred during my Medical Murray internship and was a great contribution to their Verification and Validation testing in a unique way! I am extremely experienced in machine tools, like Lathes, Milling Machines, and Drill Presses, so it was fun to apply my previous experience to a new challenge. The Solidworks for this part was also extremely challenging due to the unique holes that needed to be placed. It wasn't possible to just mirror the holes because some needed to be deeper or more off-centered than others. It was really rewarding to see the prototype cut the testing prep time from ~2 minutes to ~15 seconds! The repeatability testing with Minitab was also a new experience for me, so it was great to be exposed to that.

The catheter or tube is inserted into the small hole in the top (Black Arrow)
Once the desired amount of the catheter or tube sticks out, the rubber ring on the end keeps the catheter in place and the punch tool is inserted into the 3 holes on the sides (Red Arrows)
This creates perfect skived holes in desired locations for drug delivery or drainage
