Touchstone Systems / Paxar – Mobile Blood Tracking
Evolved Software Studios was commissioned to develop mobile blood scanning software to a thoroughly detailed specification for Touchstone Systems which provides laser-scanning handheld units immediate access to blood transfusion across– and between – hospital and mobile units complete with data interfaces to popular laboratory information management systems.
The purpose of the software was to identify patients, blood product items and to control the access of the blood product; to ensure that only the correct blood product is used for the correct allocated patient and that a blood product is not re-used and disposed of safely.
The technology was primarily .NET Compact Framework 1.1 running on Windows CE 4.0 and SQL Server 2000 with an ASP.NET management back end console.
Subcontracted for Touchstone Systems for Avery Dennison.

Dorset County Hospital NHS Foundation Trust has appointed Avery Dennison Corporation’s Printer System Division to deploy one of its Tervia blood tracking systems across all eight of its sites by June.
In 2005, the EU introduced The Blood Safety and Quality Regulations 2005, which stated all hospitals must have in place a blood recording mechanism. The supplier says that, to date, it believes very few hospitals have implemented a technology-based recording system, leaving room for human error.
The company adds: “Thousands of blood samples are taken annually and some rejected due to human error. Rejected samples are typically labelled incorrectly, and such inaccuracies can lead to patients receiving the wrong blood type.”
Tervia allocates each patient an individual barcode, printed onto their admission wristband. This code can then be scanned using a Tervia Pathfinder hand-held terminal each time blood is taken or received, after which the terminal prints a label containing the patient’s details, which can then be positioned on the blood sample. Once blood is “allocated” to the patient, tracking the blood unit and matching it to the right patient at any stage of the transfusion process becomes simple.
