Role of Vacuum Decay Technology in Medical Device Package Inspection

Role of Vacuum Decay technology in medical device package inspection

Apart from validating the functionality and design of medical devices, ensuring package integrity is crucial to make sure that the product reaches the end-user intact. Packaging and delivery formats available for medical devices range from porous flexible packaging to non-porous rigid containers. Each packaging format has a unique set of characteristics and requirements, which necessitates a comprehensive approach while selecting an appropriate inspection technique.

With increasing innovations in packaging formats and materials, packaging challenges have also increased. Among other medical devices, Class III medical devices pose the highest level of risk associated with ensuring package integrity. Such devices sustain or support life and are implanted. Examples of Class III devices include pacemakers, cardiovascular stents, respiratory ventilators and breast implants. Since these devices are directly placed into human bodies, even a minute breach in the packaging can pose significant risk to patient safety. Hence testing container closure integrity (CCI) of medical devices is crucial.

Vacuum Decay is a non-destructive Container Closure Integrity test method focused on package integrity and detection of leak paths. Compared to manual inspection and other non-deterministic test methods, Vacuum Decay offers quantitative, deterministic and reliable test results to ensure package integrity. Vacuum decay technology is capable of accommodating a wide variety of packaging formats including filled and sealed rigid, semi-rigid and flexible packaging made of non-porous or porous materials. This test operates by placing packages in a well fitted evacuation test chamber, which has an external vacuum source. The vacuum levels are continuously monitored to identify any variations from a pre-determined targeted vacuum level. A defect in the package will cause air to escape from the package into the test chamber. On the other hand, packages without any defect hold in the air, maintaining constant chamber vacuum level. Vacuum Decay technology has been proven over years to be one of the most practical and sensitive vacuum-based leak detection solutions.

PTI’s VeriPac inspection technique is an ASTM approved (F2338), FDA recognized testing method capable of evaluating wide range of high-risk package applications. It can be efficiently incorporated into the packaging process to ensure quality, reduce waste and allow operators to have a proper understanding of package integrity. Multiple vacuum supply types along with single or dual high-resolution transducers configuration enables the VeriPac series to provide fast and reliable test results that are quantitative and deterministic. It is an ideal solution for medical device manufacturers to ensure that the product meets regulatory standards. Based on packaging materials used and the level of test sensitivity required, manufacturers can select the appropriate VeriPac model.

PTI has revolutionized Vacuum Decay technology with the development of next generation PERMA-VAC technology, that offers increased test sensitivity and repeatable results. The technology is capable of detecting leaks in the MALL range for parenteral packaging and can accommodate a variety of flexible and semi-flexible package formats. The advancements in PERMA-VAC technology has made the VeriPac series the most reliable and practical vacuum-based leak test method available today.

Benefits of Vacuum Decay technology:

  • Non-destructive, non-subjective, no sample preparation
  • Capable of detecting defects down to 0.05 ccm
  • Accurate, reliable, repeatable results
  • Supports sustainable packaging and zero waste initiatives
  • FDA recognized standard for package integrity testing
  • ASTM test method F2338
