In an in-vitro study comparing products, only with UnoMeter™ Safeti™ Plus Urine Meter were bacteria not found at the bag to meter connection after seven days in all samples taken.1

The study compared Bard™, Kendall™, and UnoMeter™ devices in preventing migration of Proteus mirabilis in a simulated bladder model system. Four samples were taken at each of eight locations within the model after 2, 4, and 7 days respectively. *1

Summary of in-vitro test results*1

  • In the UnoMeter™ Safeti™ Plus urine meter, bacteria remained in the collection bag and did not progress to the measuring chamber or the catheter.
  • In both the Bard™ and Kendall™ devices, bacteria were found in the measuring chamber.
  • The in-vitro study demonstrated greater bacteria growth with the Bard™ and Kendall™ devices.
  • With the Bard and Kendall devices, bacteria growth was found in all four samples at the sampling site at 7 days.
