Autoinjector Testing System | Root Cause Analysis

Instron’s Autoinjector Testing System uses a high-resolution video camera, along with the machine vision camera, to provide critical visuals to aid in root cause analysis when a device failure occurs.
Some device failures are clearly detectable based on the calculated results, data curves, or the appearance of the device itself. Other failures are not obvious until the entire sample batch has been tested and statistically analyzed (K-value). In either scenario it is important to determine whether a bad result was truly a device failure or simply the result of a testing error. Root cause analysis for failed devices can be an extremely time-consuming process requiring significant retesting and leading to costly delays.
The autoinjector system’s high-resolution camera records a video of the injection. Visualizing the injection provides useful insights to understanding discrepancies in delivered volume, needle length, and injection time. In addition, the machine vision camera used to measure injection time and needle depth captures injection images that provide insight into the accuracy of the needle depth calculation. These capabilities provide the means to analyze sample results post-test and reduce the time required for root cause analysis studies in production environments.
