  • Publication number: 20220088297
    Abstract: IV filters are described herein. An IV filter includes a body, a filter media, and a bulb. The body defines a body volume. The filter media is disposed within the body volume. The filter media defines an inlet portion of the body volume and an outlet portion of the body volume. The filter media permits inlet flow from the inlet portion of the body volume to the outlet portion of the body volume and captures particulate from the inlet flow. The bulb defines a bulb volume in fluid communication with the outlet portion of the body volume. The bulb is deformable to compress the bulb volume and direct back flow from the outlet portion of the body volume through the filter media and into the inlet portion of the body volume, displacing particulate captured in the filter media into the inlet portion of the body volume.
