Publication number: 20140198601Abstract: The present invention relates to a device for producing a hardenable mass, preferably bone substitute and/or bone reinforcing material or bone cement or similar material. A mixing container (3) has a mixing space (4) in which at least one powder and at least one liquid component (5, 6) are mixed to provide the hardenable mass (2). A piston means (7) is provided in the mixing space (4) of the mixing container (3). At least one means (8) which is rotatable relative to the mixing container (3) cooperates with the piston means (7) for, in a retaining position (P1), retaining said piston means (7) relative to the mixing container (3) and, by rotation to a release position (P2), releasing the piston means (7) such that said piston means can move in a direction (U) towards at least one opening (49) through which said mass (2) can pass out of the mixing space (4).Type: ApplicationFiled: January 16, 2014Publication date: July 17, 2014Applicant: Bone Support ABInventors: Lars LIDGREN, Sven JÖNSSON, Torgny LUNDGREN, Östen GULLWI, Fritz BRORSSON

Patent number: 8662737Abstract: The present invention relates to a device for producing a hardenable mass, preferably bone substitute and/or bone reinforcing material or bone cement or similar material. A mixing container may include a mixing space in which at least one powder and at least one liquid component are mixed to provide the hardenable mass. A piston may be provided in the mixing space of the mixing container. A screw device may be connectable to the mixing container such that the screw device may be configured to impart by screw movements a discharge movement to the piston to discharge the hardenable mass from the mixing space.Type: GrantFiled: September 13, 2012Date of Patent: March 4, 2014Assignee: Bone Support ABInventors: Lars Lidgren, Sven Jönsson, Torony Lundgren, Fritz Brorsson, Östen Gullwi
