Device for the mixing of polymethylmethacrylate bone cement and for storing a monomer liquid and a cement powder as starting components of the bone cement, comprising a cartridge having an internal space closed on one side by a mobile dispensing plunger; a monomer container for a monomer liquid and/or a connector for attachment of a monomer container which can be opened in the device so that the monomer liquid flows from the monomer container into the device; and a connecting conduit through which the monomer liquid can be guided into the internal space of the cartridge; having a pumping plunger that can be shifted axially in the hollow cylinder arranged in the hollow cylinder, which can be used to push monomer liquid from the hollow cylinder through the connecting conduit into the internal space of the cartridge by actuating the pumping plunger.

A portable chemical reagent mixing device is disclosed. The portable device has stabilizing guide rails to keep the chemical reagent pack in place. The device includes a mold holding a motor which has a gear at the top that presses against a gear contained at the side of a chemical reagent pack. A power source connects to the motor by electrical wires that can be secured and concealed in the base or platform of the invention. The invention has a back guard plate that houses an adjustable spring coil in place which helps secure the reagent pack in place so that the gear of the reagent pack is pressed against the gear attached to the top of the motor to agitate the contents of a chemical reagent pack to facilitate mixing.

Disclosed herein is a system for creating an injectable and flowable cold slurry, the system comprising a housing; a mount operatively connected to the housing configured to accept a container; a first motor configured to move the mount from a first position to a second position; a second motor; and a drive shaft in communication with the second motor, wherein the drive shaft is configured to rotate to cause an internal volume of the container to be transformed into the injectable and flowable cold slurry.

A system for mixing content of a container comprises a container includes an interior mixing element, an exterior drive system and a mixing device comprising an exterior bearing for coupling the exterior drive system to the interior mixing element of the container. The exterior bearing provides a driven non-rotating, nutating motion that drives the interior mixing element of the container so that it performs a mixing motion inside the container.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.

A bioreactor system includes a support housing having an interior surface bounding a compartment. A rack is secured to the support housing in alignment with the opening. An elongated first shaft has a first end and an opposing second end, the first end of the first shaft being secured to the rack. A structure is secured to the first shaft at or towards the second end of the first shaft, the structure outwardly projecting away from the first shaft. A collapsible bag bounds a chamber and is at least partially disposed within the compartment of the support housing. A member projects from the collapsible bag and passes through the opening on the support housing, the structure supporting or restraining movement of the member.

A manual mixer serves to facilitate mixing and agitating materials for use during surgery. The manual mixer includes a mixing assembly and an actuation assembly for actuating the mixing assembly. The mixing assembly includes at least a paddle portion and a plunger portion. The plunger portion is simultaneously capable of rotational movement with the paddle portion and movement upwardly or downwardly along the paddle portion. Rotation of the paddle portion serves to facilitate mixing and agitating of the materials, and downward movement of the plunger portion serves to facilitate dispensing of the materials from the manual mixer.
