Medical Device Counter Inspection

Medical Device Inhaler Incremental Counter Verification


The purpose of this application is to verify the correct three digits are present and aligned on the incremental counter on a medical inhaling device and verify assembly completion.  The incremental counter digits represent the number of device dosages that remain within the medical device.


  • Multiple inspections methods deployed within a single program.
  • Custom lighting solution permits the incremental counter digits to be visualized through a molded plastic window within the device.
  • System was integrated into an OEM rotary machine control system that assembles the medical device, tracks, and rejects the product at designated stations.


  • System ensures the proper number of doses is displayed to the end user out of the box.
  • The new system reduces potential production downtime associated with false failures due to improper/poor pattern match or OCR analysis by prior system.
  • The solution reduces the risk of a potential recall due to assembly verification of counter digits and active system actuation.
