Abstract
A reservoir for the collection, purification, and storage of blood during surgical procedures which comprises a hollow blood storage casing having a hollow, perforated member within said casing extending from end-to-end thereof. Blood defoaming means and a filter are carried by the hollow member, so that the blood defoamer and filter are noncollapsible, and extend the entire length of the chamber within the casing, with one of the ports communicating with the interior of the hollow member, so that blood passes through the perforations of the hollow member and defoamer-filter means.
