<p>An autotransfusion device (10) having a rigid cylindrical housing (12) with an end wall (14), a movable piston (20) located in the housing, and a deformable collection bag (32) attached between the end wall and the piston. When the piston (20) is moved towards the end wall, collapsing the collection bag, the piston is rotated to twist the collection bag and prevent the collection bag from being seized between the housing wall and the piston. The autotransfusion device also includes an automatic air purge unit (52) and an auxiliary air purge unit (60) which is used when the automatic air purge unit malfunctions. In order to facilitate the filling of the collection bag to capacity, a length to diameter ratio of 1:1 is preferred. </p> |
