Case Study : NHS trust saves 8% a year on injection consumables with reservoir CT Motion Injector


A major UK hospital wanted to move towards weight-based contrast dosing instead of a standard dose of 100ml for all CT patients, hoping to reduce the cost of consumables and to allow the hospital to reduce their contrast extravasation rate, avoiding discomfort and potential tissue damage for their patients.


Our Medtech team introduced them to the Ulrich CT Motion injector which:

  • Allows users to test the cannula and injection site in situ with saline at the same flow rate as the contrast injection
  • Uses just two disposables, one patient line to be discarded after single use and a non-volume limited, single piece 24-hour set, which needs changing only once every 24-hour period
  • Includes training for users plus control console video tutorials to help new users
  • Offers Bluetooth connectivity to facilitate installation and updating


  • Cannula test reduces extravasation
  • Two disposables, including single piece 24-hour set, which needs changing once every 24 hours saves time and money
  • Bluetooth connectivity to CT scanner meant no installation costs and no works involved
  • Average contrast use with one CT motion per patient dropped to 74ml from 100ml with old injection system. Typically, only 50ml of contrast needed for a CPTA
  • When all syringe-based injectors replaced with CT Motion Injectors, QEHB estimates they save 8% per year on injection consumables and significant reduction in waste for incineration.
