An assembly for preparing and dispensing a paste, preferably bone cement, includes a cylinder containing a powder and a receptacle containing a liquid. A piercing device is configured to open the receptacle to allow liquid to flow into the cylinder to be mixed with the powder. The receptacle is collapsed by a differential pressure between the cylinder and the receptacle.

Method and assembly for preparing and dispensing a paste

A device for mixing, dispensing and applying a paste, such as bone cement, has a housing (), a cylinder () for receiving the paste, and a piston () associated with a piston rod (). A mixing paddle () is provided with ridges () for engagement with grooves () on the piston (). By this engagement, the paddle-piston assembly (-) can be rotated after removal of a safety pin () and interconnected by a jamming mechanism (). After this interconnection, the paddle-piston assembly (-) is used to push the paste inside the cylinder () and out thereof for dispensing. A low-friction piston rod locking mechanism () is provides as well.

Device for mixing and delivering bone cement

A cardiopulmonary system is disclosed which is intended for oxygenation of a patient's blood during heart surgery in which the patient's own lungs are used for such oxygenation. The cardiopulmonary system includes use of a blood reservoir which includes at least two chambers, one for venous blood collected from the patient's heart or a major vein and one for arterial blood, and include filters for filtering both the venous and arterial blood as they enter the respective chambers.
