Patent ID: 7980754

Claim:
Method for bringing a powder and a liquid component, in contact with each other for mixing thereof to form bone cement, wherein: the powder component (P) is placed in a mixing container ( 1 ) in which the mixing shall occur and the liquid component (M) in at least one liquid container ( 18 ) from which said liquid component (M) is transferred to the powder component (P) in the mixing container ( 1 ), a vacuum is generated in the mixing container ( 1 ), the liquid container ( 18 ) is opened by means of at least one cannula ( 14 ) through which the liquid component (M) can be brought to flow from the liquid container ( 18 ) to the mixing container ( 1 ), the cannula being located between a first and a second end portion ( 33 , 34 ) of the mixing container ( 1 ) and protruding from said mixing container ( 1 ) in a radial direction relative to a geometric longitudinal axis (A) of the mixing container ( 1 ), the vacuum is brought to suck the liquid component (M) from the liquid container ( 18 ), through the cannula ( 14 ) and into the mixing container ( 1 ) to the powder component (P) therein, and/or the liquid component (M) is pressed into the mixing container ( 1 ) through the cannula ( 14 ) while the liquid container ( 18 ) is compressed because of the pressure difference between the vacuum in the interior of the liquid container ( 18 ) and the air pressure outside said liquid container.
