The present disclosure relates to systems and methods for mixing and injecting fluid treatment, such as cement to treat bone or hard tissue. In some embodiments, a mixing apparatus may facilitate mixing within a syringe. Additionally, the syringe may be configured to extract bone cement from a cement mixer. A syringe for mixing and injecting cement may include a detachable handle that may be detached after extracting bone cement from a mixer to facilitate coupling to a high-pressure syringe for injection.

A method includes the step of receiving a first weight value from a sensor associated with a feed mixer. A first rotation speed associated with the first weight value is monitored. A second weight value is received from the sensor associated with the feed mixer and a second rotation speed associated with the second weight value is monitored. A mixing profile is generated based on the first weight value, the second weight value, the first rotation speed, and the second rotation speed. In one embodiment, a first feed ingredient is associated with the first weight value and a second feed ingredient is associated with the second weight value.

The present invention relates to a method of making a composition, the composition comprising a cross-linked polymer and water, comprising at least the following steps: a) providing a first mixture, comprising at least one polymer and an aqueous alkaline solution; b) generating a gel by cross-linking the at least one polymer with a cross-linking agent; c) neutralizing the generated gel by using a neutralization solution; d) optionally adding a second mixture, comprising a cross-linked and/or non-cross-linked polymer and water, to the neutralized gel obtained in step c); e) dialyzing the gel obtained in step d) or dialyzing the gel obtained in step c) and optionally subsequent addition of the second mixture, comprising a cross-linked and/or non-cross-linked polymer and water; and f) filling the dialyzed gel obtained in step e) into a container, wherein at least two or three or four or five or all of steps a) to f) are automated.

In the case of a rotor (109) for a device for mixing powder and liquid, which device has a stator which interacts with the rotor (109), at least some shear blades (124) are of wedge-shaped form and are inclined with one face side (233) in a flow direction (239). This has the result, in the case of an effective diversion at side walls (227) situated at the front in a flow direction (239), of an intense shear action at the face sides (233) and of a relatively low risk of formation of deposits and adherent accumulations on the side walls (230) situated at the rear in the flow direction (239).

A device for processing a product mass, including a container for receiving the product mass, at least one product mass processing tool in the container, which is provided to act on the product mass, and at least one sensor means having a dielectric sensor, wherein the sensor means is arranged and formed in such a way that dielectric properties of the product mass can be detected continuously or at least temporarily by means of the dielectric sensor in an environment of the dielectric sensor. The invention further relates to a method for processing a product mass, in particular by means of a device of this type.

In the case of a rotor (109) for a device for mixing powder and liquid, a number of connecting arms (203) are formed, as a connecting structure, between an outer blade carrier plate (215), which is equipped with outer blades (127), and a shaft receptacle (117), between which connecting arms there are situated liquid outlet regions (206). This has the result, owing to a relatively high throughput with a shear action which is still sufficient, of a relatively high mixing rate and of a relatively low tendency for powder to agglutinate.
