A feedstock delivery system for injection molding includes a vessel unit that includes a vessel with an internal volume and an inlet for receipt of a feedstock. First and second dispensing units are alternatively connectable to the vessel unit and each include first and second ends, first and second valves, and a buffer chamber. The first end is connectable to the dispensing unit such that the buffer chamber is in communication with the internal volume of the vessel. The second end is connectable to an injection mold and defines an outlet of the feedstock delivery system. The outlet is in communication with the buffer chamber, and the buffer chamber is positioned between the first and second valves. The buffer chamber of the first dispensing unit defines a first chamber volume, and the buffer chamber of the second dispensing unit defines a second chamber volume greater than the first chamber volume.

A stirring and defoaming device is a stirring and defoaming device of a revolution and rotation type, wherein a vacuum unit for sucking air in each container to bring the inside of each container into a vacuum state includes sealing bodies that seal respective containers, a vacuum generation source, a suction path running toward a revolution center with each container as a starting end, passing through the revolution center to go outside the system, and reaching the vacuum generation source placed outside the system, at least part of the suction path being an independent path from the starting end in association with each container, and at least two or more vacuum measurement units, each provided in an independent path.

A bone material comprising a coherent mass of cartridge milled and demineralized bone fibers is provided, the coherent mass having no binder disposed in or on the coherent mass. In some embodiments, a bone material comprising a lyophilized coherent mass of cartridge milled and demineralized bone fibers is provided, the lyophilized coherent mass having no binder disposed in or on the coherent mass. In some embodiments, a method of making an implantable bone material is provided, the method comprising drying a coherent mass of cartridge milled and demineralized bone fibers, the coherent mass having no binder disposed in or on the coherent mass.

A mixer is disclosed including a sealed mixing chamber having an interior, and a rotating mixing bowl within the interior of the sealed mixing chamber. A stand operatively supports the sealed mixing chamber. The stand includes: a foundation, a mixing chamber base movably coupled to the foundation and positioning the sealed mixing chamber at an angle relative to horizontal, and a linear actuator system configured to move the mixing chamber base relative to the foundation in at least one linear direction. A rotating mixing head is operatively positioned and sealingly disposed within the sealed mixing chamber, the rotating mixing head rotating within the rotating mixing bowl. The mixer and a related method provide for ceramic suspension mixing with reduced cooling and possibly without cooling the suspension.

A vacuum mixing system for the mixing of polymethylmethacrylate bone cement, comprising at least one cartridge (4) having an evacuable internal space for mixing of the bone cement, a pump (18) for generating a negative pressure, and a connecting conduit (12) connecting the internal space of the at least one cartridge (4) to the pump (18) for generating a negative pressure, an integrated energy reservoir (28) for driving the pump (18) that is or can be connected to the pump (18) and has energy for at least one pumping process of the pump (18) stored in it, whereby a negative pressure can be generated by means of the pump (18) during the pumping process, which negative pressure can be used to evacuate gas from the internal space of the at least one cartridge (4) through the connecting conduit (12).

A vacuum blender having the ability to reduce oxidation of ingredients for a more nutrient-rich product. The blender includes a container for holding ingredients to be blended, the container being open at a top end and having blender blades at a lower end, a lid for covering the open end of the container, and a base having a motor contained therein for driving the blender blades, an interface for coupling with the blender blades of the container, a vacuum system for effecting a vacuum to the container and electronic controls for operating the motor and vacuum system. The vacuum system is configured to couple with the lid to draw a vacuum from the top of the container when activated.

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.
