ABSTRACT:
A softshell blood reservoir for heart-lung machines is symmetrical about a central vertical axis and is divided into two chambers: a small main chamber accessed by the blood inlet and outlet connectors, and a larger storage chamber accessed from the main chamber through a selectably closable passage. This arrangement greatly reduces the priming volume of the reservoir without substantially affecting its total capacity, and enhances the mixing of venous and cardiotomy blood.
