Abstract

An arterial blood filter device for use during cardiovascular surgery. The device includes an outer housing having a top and bottom section, an inner housing, and a filter element. The filter element is disposed within the outer housing, and the inner housing is disposed between the filter element and the housing. The inner housing is separate from the outer housing and extends the entire axial length of the filter element. Fluid enters the device through an inlet. The majority of the fluid then rises in a centripetal motion where any large air bubbles exit through a vent at the top section of the outer housing. The fluid then flows through openings in the top and bottom of the inner housing. After entering the inner housing, the fluid passes through a filter element, where filtration takes place, and exits through the bottom section of the housing through an outlet.
