Measurement & Laboratory Technology
A laboratory device that got quieter and easier to assemble
A complete relaunch of the Disc Remover in-vitro diagnostics device: EMC-optimised housing design, new electronics, new embedded software on our own framework semf.
The task
For nearly forty years Labsystems Diagnostics has been developing technologies for newborn screening and point-of-care testing. The company's neonatal products are in use in more than seventy countries.
The Disc Remover in-vitro diagnostics device was to be built anew. Three points settled it: assembling the previous device was complicated and slow, field service management cost time and money, and the noise level spoilt the impression of quality.
The solution
The device was built from scratch: housing, electronics hardware and embedded software. The electronics design is EMC-optimised for use inside a plastic housing. We prepared the documentation for international in-vitro diagnostics approval.
The result is laid out for long service life, low service and maintenance effort, tighter measurement tolerances and comfortable use. The housing design came about together with MKI · Matzku & Konz.
Worth noting technically
The embedded software builds on semf, our own C++ framework. That speeds development up and keeps the number of mistakes down.
The stepper motor control works to an accuracy below 0.1 millimetres. The axes find their position through light barriers with daylight compensation, and optical sensors detect a loaded sample. Control and diagnostics run remotely over USB-VCP. Test software came on top, and we used it to run the performance tests.
