Thanks to a non-contact vision system, a company was able to put medications in the hands of patients and keep shots out of their arms.
What if someone who needs a consistent dosage of drugs, such as painkillers or insulin, could easily administer the drugs himself without needles? Both patient and doctor would benefit. Of course, reliability would be paramount in such a drug delivery system. To ensure reliable operation, Aradigm Corp. designed dimensional accuracy into its new drug delivery device with help from the Quick Vision (QV) 3D CNC vision measuring machine from Mitutoyo America.
Aradigm developed the device, called the AERx pulmonary drug delivery system, for self-administered medication. This technology platform converts large or small molecules into fine-particle aerosols and deposits them deep inside the lungs. The device is a handheld aerosol dispenser with electronic controls that determine how much active pharmaceutical material is dispensed. The active substance is contained in a sleeve-like plastic disposable pouch called a dosage form (DF).
Engineers working on the project realized that the reliability of...
