A mixing device for bone cement comprising a plunger for extruding the mixed material, which plunger is also used as a cover. The plunger has spring blades adapted to be latched on a collar of the housing.

A vessel configured to contain a liquid is provided. The vessel includes a collapsible bad, a reusable support structure, a sensor, and a controller. The collapsible bag is operative to contain the liquid. The reusable support structure is operative to support the collapsible bag. The sensor is operative to measure a parameter within the collapsible bag. The controller is in electronic communication with the sensor and operative to introduce an antifoaming agent into the collapsible bag based at least in part on a signal received from the sensor.

Embodiments of the present disclosure involve methods, devices, and systems for hydrating polymers using multiple mixing chambers. Adjacent mixing chambers may be coupled using an under-over baffle, and each mixing chamber may be generally rectangular with rounded corners.

Mixing devices and associated methods are described herein. Various embodiments of mixing devices can comprise a plate configured to rotate about a longitudinal axis and a plurality of enclosures coupled to the plate. The enclosures can each include (a) at least one sidewall that defines an oblique angle with the plate and (b) a chamber configured to receive a media and a fluid. The enclosures can be fluidly coupled to a fluid source for receiving the fluid in the chambers. When the plate is rotated, the enclosures revolve about the longitudinal axis to mix the media with the fluid in the chambers.

A method for enhancing mixing and aeration of a liquid reaction medium in a toroidal bioreactor vessel includes dispensing a liquid reaction medium into an interior of a toroidal bioreactor vessel, the interior being bounded by an inner surface, a textured surface being arranged on at least a portion of the inner surface, the textured surface having a plurality of upstanding protuberances. The toroidal bioreactor vessel is rotated in an orbital motion such that there is a resonant frequency traveling wave of the fluid orbiting in one direction in the interior of the toroidal bioreactor vessel when a particular orbital speed is imparted to the toroidal bioreactor vessel.

A device for preparing a gelatin-based product may comprise a mix tank, a mix pod that is fluidly coupled to the mix tank via a pod spike, and a hot water tank, where the hot water tank is coupled to the mix pod via the pod spike. In at least one example, the pod spike may comprise an outer tube and an inner tube. In one or more examples, the pod spike of the device may comprise a hub, where a first end of the outer tube is coupled to the hub. Further, in some examples, a first end of the inner tube may also be coupled to the hub.

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

An improved drinking vessel is a drinking cup or glass having a mixing blade located on the interior bottom having a shaft passing through the bottom of the glass to a rotationally separate portion of the glass that can be spun by hand. A screen sets inside the glass just above the mixing blade to prevent ice or other large solids in the glass from contacting the mixing blade.

The present invention is directed to a fluid mixing system. In an embodiment, the fluid mixing system includes a first vessel; a second vessel disposed within the first vessel; a mixer disposed outside of the first vessel in fluid communication with the second vessel; and a media introduction port disposed outside of the first vessel in fluid communication with the mixer.
