In one embodiment, the paint pot shaking component includes a crank gear adjacent a combination gear that contacts a slide crankshaft. The slide crankshaft is coupled to a slide crank arm that is secured by slide bracket coupled to the base. A paint pot harness holds a paint pot during agitation and moves in an upward and downward motion corresponding to the motion of the slide crank arm.

An apparatus and method for mixing and dispensing bone cement is provided. The apparatus includes a mixing vessel for mixing bone cement attached to a syringe body. The syringe body having a lumen that is connected to the mixing vessel by a passageway between the mixing vessel and the lumen of the syringe body. A separator is provided between the mixing vessel and the syringe body and includes an orifice therein so that when the opening in the separator is misaligned with the lumen the passageway is blocked and when aligned the passageway is continuous with the lumen so that bone cement can pass into the syringe body. A plunger is provided and is slideably movable along the longitudinal axis of the syringe body so as to advance the bone cement out of the distal end of the syringe.

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 storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge having a cylindrical inner chamber, a dispensing plunger that is axially displaceable in the inner chamber of the cartridge, a partition disposed axially in the tubular cartridge, and a cartridge head which closes one end of the tubular cartridge. The cartridge head has a slot-shaped opening, wherein the partition protrudes from the inner chamber of the cartridge through the slot-shaped opening of the cartridge head, wherein the partition divides the cylindrical inner chamber of the cartridge bounded by the dispensing plunger and the cartridge head into two cavities that are spatially separated from one another. A first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity, wherein the partition is removable through the slot-shaped opening of the cartridge head so that the two separate cavities are connected to one another after the partition is removed.

A stirrer assembly for, in use, stirring liquid in a receptacle with the receptacle lid in place, which includes a receptacle receiving portion which is locatable inside the receptacle, a first guide member which is mountable onto a floor of the receptacle for rotatably guiding the receptacle receiving portion, a second guide member which is defined centrally a receptacle lid and extending downward therefrom, for in use, rotatably guiding an upper region of receptacle receiving portion, a sealing member for releasably sealing the second guide member, and a drive member which is connectable to the upper region of the receptacle receiving portion, for in use, transmitting torque to the shaft upon rotation of the said drive member.

A stirring system for a bucket having a sidewall configured to form an inner cavity for containing liquid therein. The system a lid having a center hole extending through the thickness of the lid; a shaft extending from a first end to a second end, the shaft is configured to extend through the center hold of the lid and into the inner cavity; a quick-release device secured to the first end of the shaft; an upper perforated stirring paddle rigidly attached to and extending from the shaft; a middle perforated stirring paddle rigidly attached to and extending form the shaft, the middle perforated stirring paddle is configured to extend in a first plane parallel to the upper perforated stirring paddle; and a lower perforated stirring paddle secured to the second end of the shaft and extending along a second plane, the lower perforated stirring paddle having a first length equal to a second length of the upper perforated stirring paddle plus a third length of the middle perforated stirring paddle.

The invention provides a bone cement mixing assembly including a mixer, a syringe barrel and a movable plug cover. The mixer includes a stirring rod and a stirring barrel. The stirring rod has holding end, a rod body and a stirring end. The stirring barrel has a barrel cover, a first barrel open, a first barrel body, a first barrel bottom, and a stirring space located in the first barrel body. The syringe barrel has a second barrel open, a second barrel body, a second barrel bottom, and an injection space located in the second barrel body. In this way, the complete-stirred bone cement in the stirring barrel can be directly collected and pushed into the syringe barrel through the movement of the movable plug cover to achieve the effect of completing the preparation of the bone cement quickly and efficiently.

A mixing container with an internal mixing blade has an extraction funnel, a main housing, a rotatable base cap, a mixing blade and a gear mechanism. The extraction funnel has a first end with a maximum diameter and narrowing to a second end of a minimum diameter at a neck portion. The main housing includes a mixing chamber. The rotatable base cap with an internal gear is attached to and is rotatable relative to the main housing. The mixing blade has a plurality of prongs extending from a shaft. The prongs are in the mixing chamber and the shaft extends through an opening in the main housing to inside the rotatable base cap. The gear mechanism has at least one gear, each of the at least one gears is connected to or intermeshed with the internal gear of the base cap and the gear of the shaft end.
