Ambulatory infusion devices and filter assemblies for use with same

An ambulatory infusing device, comprising:

• a housing;
• a reservoir defining an interior volume;
• a divider wall associated with the housing and having an inner surface that faces into the reservoir interior volume and that includes a channel;
• and
• a filter assembly including
• a filter assembly housing with a housing filter portion having a side wall and an end wall that define a filter supporting volume, the side wall including a side wall aperture that extends through the side wall to the filter supporting volume and that is aligned with the channel,
• a filter located within the filter supporting volume, and
• a bubble guard, including a bubble guard wall and at least one bubble guard aperture that extends through the bubble guard wall, associated with the filter assembly housing such that the bubble guard wall is located in spaced relation to the filter.
