Abstract:
1. A system, comprising: a reservoir for receiving an infusion medium from an infusion medium container, the infusion medium container having an interior volume for holding the infusion medium, the reservoir comprising: wherein the collapsible housing and the chamber housing are configured such that when (i) a gaseous pressure within the interior volume of the chamber housing is less than a particular gaseous pressure within the interior volume of the infusion medium container and (ii) the collapsible housing is in the collapsed state and (iii) a path for transferring the infusion medium is established between the interior volume of the infusion medium container and the interior volume of the collapsible housing, the collapsible housing and the chamber housing allow for a pressure differential between the interior volume of the chamber housing and the interior volume of the infusion medium container to cause the collapsible housing to expand and to cause the infusion medium to be pushed from the infusion medium container to the collapsible housing; the system further comprising: wherein the reservoir is supported by the base.
