A unique benefit of the iPRECIO pump is its ability to be refilled after implantation, while in the animal. Test solutions can be exchanged or replenished via percutaneous access to the pump through a re-sealable septum. This feature enables researchers to perform chronic infusion studies without having to replace empty pumps, eliminating the need for multiple surgeries during the course of the study. Pump refilling can extend the duration to up to six months (at 1 ul/hr flow rate) for the iPRECIO SMP-200 pump, or up to 67 days (at 0.1 ul/hr flow rate) for the iPRECIO SMP-310R pump, at which point the installed battery is depleted.
The iPRECIO reservoir is elastic and its geometry allows gentle palpation to approximate the level of fluid in the reservoir and confirm pump performance. Furthermore, the iPRECIO management software calculates refill timing so the user can adjust the volume as needed throughout the study.
