More Information
Summary:Infusion apparatus includes a housing with an infusate chamber in the housing and means for conducting infusate from the chamber through a restrictive outlet passage to an additional small chamber having an entrance port closed by a self-sealing penetrable septum. An exit tube from the small chamber leads directly to a cannula at the infusion site so that liquid can be injected into the small chamber through its septum and delivered directly to the infusion site without backflowing into the infusate chamber.
