Touchstone Systems / Paxar – Mobile Blood Tracking

Project description

A blood unit used on the wrong patient is not a data-quality issue. EU Blood Safety and Quality Regulations 2005 needed a trail that a ward could actually run, and paper labels were still rejecting samples and, worse, mismatching units.

We wrote the software on the Windows CE scanning guns: identify the patient, identify the product, decide whether that unit is allowed, and refuse it a second time. A management console sat behind the guns, with interfaces into the laboratory systems. Dorset County Hospital later rolled Tervia Pathfinder terminals across eight sites; this was the software that had to say no.

Subcontracted for Touchstone Systems for Avery Dennison. We did not invent transfusion safety. We made the check that stops the wrong bag.
