The inlet channel (41) is arranged asymmetrically with respect to the longitudinal axis (A).

Storage and mixing systems for pasty two-component polymethyl methacrylate bone cements comprise a tubular cartridge having a cylindrical inner chamber, a cartridge head, which closes one end of the tubular cartridge at the front side, a partition that is disposed axially in the cylindrical inner chamber of the cartridge. The partition divides the cylindrical inner chamber of the cartridge bounded by the cartridge head into two cavities that are spatially separated from one another, wherein a first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity. The systems further comprising two dispensing plungers axially displaceable in the two cavities of the cartridge, wherein the dispensing plungers close the two cavities on the back side of the cavities situated opposite the cartridge head, a bending device for deforming the partition, wherein the bending device is axially movable in the cartridge and is disposed, or is to be disposed, behind the dispensing plungers, as seen from the cartridge head, wherein the bending device has a deflection surface that is inclined with respect to the axis of the cartridge and pushes the partition laterally in the direction of the inside wall of the cartridge when the bending device is pushed into the cartridge.

A storage and mixing system, for pasty two-component polymethyl methacrylate bone cements, comprises a cartridge with a cylindrical interior, a cartridge head that closes an end of said cartridge, a partition wall axially disposed in the cylindrical interior of the cartridge, wherein said partition wall is connected to the circumferential surface of the cylindrical interior of the cartridge and divides the cylindrical interior of the cartridge delimited by the cartridge head into two spatially separate cavities. The first cavity includes a first pasty cement component and the separate second cavity includes a second pasty cement component, two delivery plungers close the two cavities on the side of the cavities opposite the cartridge head. At least two cutting edges are disposed on the front side of the sleeve-shaped connecting means facing the cartridge head, such that the at least two cutting edges cut off the partition wall from the cylindrical inner wall of the cartridge as at least one cut-off strip when the delivery plungers are advanced towards the cartridge head in the cavities with the connecting means, and wherein the sleeve-shaped connecting means comprises a deflecting surface which is inclined to the axis of the connecting means which, on advancing the connecting means, presses the at least one cut-off strip of the partition wall towards the inner wall of the cartridge.

A storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge with a cylindrical interior, a cartridge head that closes one end of the tubular cartridge, a partition wall axially disposed in the cylindrical interior and dividing the cylindrical interior into two spatially separate cavities, the first cavity including a first pasty cement component and the second cavity including a second pasty cement component, two delivery plungers disposed movably in the two cavities and connected via a connecting means, wherein a wedge or cone having a cutting edge on the front side thereof facing the cartridge head is disposed on the connecting means, such that said cutting edge cuts open the partition wall when the delivery pistons are advanced towards the cartridge head and the wedge or cone presses the cut open parts of the partition wall towards the inner wall of the cartridge.

A system for dispensing a curable composition includes a dual barrel syringe including a first syringe barrel with a first plunger, and a second syringe barrel with a second plunger. A static mixer is connected with distal ends of the first and second syringe barrels. The first and second plungers are moveable toward the distal ends of the first and second syringe barrels for expelling first and second components of a curable composition from the distal ends of the barrels into the static mixer for mixing the components to form the curable composition. A flexible spreader connected with a distal end of the static mixer has a flat dispensing opening, and a plurality of channels extending to the flat dispensing opening to dispense the curable composition. A hot gas blower generates a hot gas stream flowing distally over the distal end of the flexible spreader for curing the curable composition.

An adapter for connecting a separated-outlet fluid cartridge to a single-inlet static mixer includes a locking portion and a connecting portion. The locking portion has at least one locking element to lockingly engage the mixer housing so as to inhibit rotation between the locking portion and the housing. The connecting portion is received within the locking portion and has first and second fluid inlet members to be coupled to respective first and second fluid outlets of the cartridge for receiving fluid from the cartridge, and a fluid outlet member is sealingly coupled to the mixer for directing fluid into the mixer. The locking portion is selectively rotatable about the connecting portion between unlocked and locked positions relative to the cartridge when the connecting portion is coupled to the cartridge. Consequently, the adapter advantageously enables dispensing with a separated-outlet fluid cartridge in combination with a single-inlet static mixer.
