A mixing and dispensing container for mixing and dispensing dental materials. The mixing and dispensing container includes: a plunger; an open-ended liquid receptacle adapted to receive the plunger; and a main body with a proximal end, a distal end, a chamber open at the proximal end and an aperture in the distal end. The chamber is adapted to receive the liquid receptacle. The dental capsule mixes various components of the dental materials and forms a dental paste for dispensing. The container is especially envisaged for use in mixing of components to provide a paste for dental use.

A low-cost drug compounding system that can practically fit inside of a fume hood or the like is provided. The system can use a single pump operable in forward and reverse directions (or multiple pumps) to compound complex mixtures particularly including those requiring the creation of solutions from dry or powdered ingredients. A wireless link allows operation of the system remotely. In one embodiment, the system uses a disposable mixing tube set that can be discarded after mixing while still attached to the base ingredient containers used for the compounding thereby minimize the chance of personnel exposure.

A mixer for mixing and degassing fluids includes a revolution device having a revolution base to be driven for rotation; a first spin device connected to the revolution base of the revolution device; a first barrel connected to the first spin device to be spun by the first spin device; an transmitting coil electrically connected to a power source to generate a time-vary magnetic field; and a receiving coil connected to the revolution base of the revolution device and electrically connected to the first spin device, wherein the receiving coil rotates with the revolution base. The receiving coil receives the power from the time-vary magnetic field of the transmitting coil and produces an electromotive force to be supplied to the first spin device.

A fluid injection system is a system that enables the automatic mixing and dispensing of select additives to desired output locations. The system may include at least one supply line, at least one pumping mechanism, at least one injection assembly, and a base controller. The at least one supply line carries the supply flow from a supply source for the mixing and the distribution of the selected additives to the desired output locations. The at least one pumping mechanism facilitates the injection of the additives to the supply flow being carried by the at least one supply line. The at least one injection assembly enables the introduction of the combined additives into the supply flow via the at least one pumping mechanism. Finally, the base controller monitors the injection of the right amounts of additives as well as the correct combination of the additives being injected into the supply flow.

Examples of containers for the production of a foamed sclerosant composition are provided. The containers include a container body comprising one or more sidewalls extending between a top and a bottom of the container body and a bottom surface, a foaming space being defined in an interior of the container body. The foaming space contains a sterile gas and a mixing element configured to be operatively coupled with a rotatable actuator without the actuator entering into the foaming space. The container includes a female coupling member for mating with a syringe, and a pressure equalizer for equalizing a pressure inside the foaming space with a pressure outside the foaming space. Systems and kits including such containers are also provided. Also disclosed are methods for the preparation of a sclerosant foam which may include a pressure release before extraction of the foam and/or a continued rotation of the actuator while the foam is being extracted.

An apparatus and system for managing the level of dissolved gases in water for aquatic life that provides sufficient water with sufficient oxygen saturation, without introducing excessive amounts of bubbles, and that can adequately degas or strip harmful dissolve gases from the water. The apparatus can generally comprise a storage compartment, a filter compartment, and a pump compartment. The filter compartment can be coupled with the storage compartment and comprise a filter element. The pump compartment can be coupled with the storage compartment and comprise a venturi air intake port, a degassing vent, a pump filter element, and a pump assembly. The pump assembly can comprise a venturi nozzle coupled with the venturi air intake port and a flow pump in fluid communication with a flow pump intake port. The pump filter element can at least partially encircle the flow pump intake port.
