PRODUCTS & APPLICATIONS MEDICAL & PHARMACEUTICAL AUTOMATING MEDICAL DEVICE INSPECTION
Automated medical device inspection systems supplied by Industrial Vision Systems (IVS) are being used by blue-chip medical device manufacturers for the programmed checking of components, sub-assemblies and packs. These systems feature a customisable dial plate which can be modified to suit varying sizes and shapes of parts, and use the latest generation IVS HD digital camera technology with telecentric optics to provide high speed inspection of medical device products at up to 300 parts per minute. Capable of accommodating up to six inspection
camera stations, each utilising different light and optics for varying quality checks, these also have an integrated hopper and bowl which supplies
continuous feeding of parts, allowing the vision system to provide 24/7 continuous inspection. Typical applications include inspecting for micron level mould defects in flash and shorts, checking key dimensional data on parts, syringe body inspection for inclusions, needle tip verification and measurement, plus medical device sub-assembly checks. All machines installed and
commissioned by Industrial Vision Systems are fully
validated to GAMP/ISPE protocols for medical device and pharmaceutical manufacturing.

MEASURING MOISTURE IN OXYGEN CYLINDERS
Based in North Wales, Medical Gas Solutions (MGS) designs and manufactures lightweight, high pressure valve, medical oxygen cylinders for the ambulance service, hospitals, medical centres and other emergency services. As the company follows the stringent requirements outlined in the European Pharmacopoeia standard 2.5.28, which states that there must be no more than 67ppm moisture present in the production of Medical Grade Oxygen, the measurement and analysis of moisture is essential in detecting and avoiding high levels of moisture contamination.
PHARMACEUTICAL INSPECTION
The newest inspection technologies from Antares Vision can reach speeds up to 30,000 bottles/ hour and 300,000 tablets/hour, and are capable of detecting defects up to 40μm. The Tablets and Capsules Inspector (TCI) gently manipulates pharmaceutical products, ensuring the detection of even the smallest defect or imperfection by six colour high resolution cameras that acquire up to 12 images per product with an image resolution up to 0.002 square millimeter. Products found to be defective are automatically rejected.

A SENSOR FOR MEDICAL APPLICATIONS
Now available from Acal BFi is Honeywell’s ABP series of basic amplified board mount pressure sensors. Offering high performance and reliability, these are suitable for medical applications including blood pressure monitoring and ventilators.
This compensated, amplified pressure sensor measures just 8 x 7 x 3mm, and it has a low current consumption of 2µA with sleep mode enabled. In addition, this piezoresistive silicon pressure sensor offers 56 different pressure ranges to improve system accuracy and resolution. The ABP series is available with either ratiometric analogue
or digital outputs for reading pressure over the specified full scale pressure span and temperature range. Alongside medical applications, the sensors can also be used in
industrial applications, the company adds. Acal BFi
www.acalbfi.co.uk To help, the company has selected the
Systech Illinois MM510 moisture analyser to measure the moisture and water vapour within its medical grade oxygen. According to the company, this electrolytic, phosphorous pentoxide (P2O5) analyser is ideal, and also conforms to the European Pharmacopoeia standard. Although the moisture content in
medical oxygen can range from less than 1ppm up to 60ppm, this range can be accommodated by the MM510 which auto-ranges from 0.01 to 1000ppm. It also offers the option of auto-calibration and incorporates a new, long life, P2O5 electrolytic moisture sensor of the highest quality.

www.systechillinois.com DETECTING MEDICINE PACKAGES IN PHARMACY PICKING SYSTEMS
Light section sensors, such as Leuze electronic’s line profile sensor (LPS), operate according to the ‘light-section method’, a commonly used method for optical shape recognition. The LPS light section sensors, which combine the laser as a light source and the camera in one housing, measure just 160 x 74 x 56mm. Thanks to the benefits they offer, Gollmann Kommissioniersysteme, a manufacturer of picking machines for pharmacies, selected the LPS 36. The company produces a roll-fronted system, the
‘wandering gap’ storage principle, which achieves a very high storage density. Depending on the design, the flexible picking systems in a pharmacy hold several thousand packages in every meter of housing length. Each package lies ready in its own storage space for direct and fast access and, even in the basic version, these systems allow for the storage and immediate availability of 100 packages in less than eight minutes, as well as the retrieval of 350 packages per hour. The stored packages can be dispensed directly at the machine or at any location in the room by means of an optional conveyor system. The light section sensors from Leuze electronic are used in fully automated

warehousing modules, which can optionally be adapted to the picking machines. With these, the picking machines are loaded fully automatically within seconds. Goods deliveries are simply emptied unsorted into a container and separated on a conveying belt. An LPS 36 light section sensor then detects the contour, position and volume of the individual medicine packages as they pass through. With the height information provided by the light section sensors, reliable detection of all packages was ensured right from the start. Using the 3D coordinates ascertained for the medicine cartons, the handling system in the warehousing module can correctly and gently receive the packages and deposit them in the transfer bin of the picking machines. The Ethernet interface of the LPS 36 is used for data transfer. “With a line length of 600mm and a measurement range of up
to 800mm, we detect the entire range of package sizes, from the smallest eye ointment to the largest dressing package,” explained
