Laboratory Automation
Clinicians often place a great deal of blind faith in the results of IVD medical devices. Staff assumes if a device gives a result, then that result must be correct. Glucose meters, pregnancy tests, blood gas analyzers and coagulation devices are all considered equivalent to central laboratory instrumentation, only faster. Yet, central laboratory testing is conducted under well monitored and controlled conditions, while these point-of-care testing (POCT) devices are subjected to a variety of...
The anatomic pathology lab is rapidly evolving and, if current trends continue, fully automated digital pathology will soon become the norm. Not every lab scans every processed specimen slide to create digital images—not yet, at least. But compare the speed and convenience of transmitting digital files via the Internet or intranet with physically transporting glass slides, and the transition to digital pathology seems inevitable. The biggest innovations in medical diagnostic systems are...
Diaphragm metering pump Largely by default, valveless piston pumps historically have reigned as the “pumps of choice” for midrange precision fluid dosing and metering in IVD systems. Other technologies-most notably peristaltic hose pumps and high-precision syringe pumps (the simplest form of a piston pump)-have been available as alternatives. But in comparison to valveless piston types, these alternatives have not made significant headway in IVD applications because of...
  Shopping for parts, components, services, and new technologies at the Clinical Lab Expo next week? You're in luck. Here's just a tiny sampling of what will be on display there. Isolation Miniature Valves Solenoid-operated valves use a flexible diaphragm to isolate the solenoid actuation mechanism from the fluid path. When the valve is energized, the solenoid retracts an armature that is attached to a flexible diaphragm. In a normally closed valve, this raises the diaphragm, allowing...
The Clinical Lab Expo will feature new science and technology in every area of clinical diagnostics, automation, information systems, point of care, OEM, and biotech. Roughly 750 organizations will occupy about 2000 booths. According to Clinical Lab Expo's Website, "You will see more products in every clinical lab discipline than at any other show." Find What You Need The Clinical Lab Expo will have special sections for special products. Visit the special sections for point-of-...
Molecular diagnostics, POC diagnostics, and hematology are expected to see continued growth. The current IVD market includes immunochemistry, molecular diagnostics, blood donor screening, hematology, hemostasis, and point-of-care testing. As the IVD market evolves to become more efficient and less costly, a shift from manual testing to automated methods is essential. Furthermore, as patient care shifts from the hospital to the alternate care setting, IVD is likely to follow. Overall...
A laser micromachining system was developed for universities and corporate research to fabricate microfluidic, MEMs, and medical devices in a rapid prototype fashion, with tolerances approaching 1 micron. Traditionally, MEMs devices are fabricated using traditional semiconductor lithography, but the multistep process takes significant time. The RapidX250 system uses a multiwavelength excimer laser (193 nm and 248 nm) to directly fabricate the structures in a single step, drastically reducing...
Easy-to-use software keeps track of inventory items by location.  CheckMate Stockroom software can track inventory in the main stockroom as well as at other locations. It tracks inventory by multiple units of measure (ml/sq in) and records lot numbers, serial numbers, and expiration dates. Reports provide replenishment information and usage. When used with CheckMate JobData job tracking and Toolroom tool/equipment tracking, the Stockroom software becomes a production management system....
2010 was a catalyst year for computing. When Apple launched the iPad tablet computer in April, it brought the keyboard and mouse one step closer to extinction. Similarly, with Windows 7, Microsoft added true touch-screen support to desktops, tablet PCs, and smartphones. Google made an entrance as well, with Android, an operating system for smart phones and slates. Touch screen will be the dominant user interface for years to come, according to DisplaySearch.com, which monitors and reports on...
When designing an IVD or other medical instrument, most engineers look at the requirements as a group of mechanical, fluidic, electrical and software systems interacting to produce a desired result. Often, these engineers see only part of the picture. Quite a few factors come into play both during design and manufacturing and after the instrument is deployed. Following the design phase is integrating systems, performing validation, gaining approvals, manufacturing, and servicing in the field....
