Mixing device (1) and fluid mixing method, by means of successive transfers between syringes. The mixing method comprises placing a pair of syringes (2, 3) in the mixing device (1), adjusting a variable fixing element adaptable to the pair of syringes (2, 3) and selecting and running a mixing programme, being the mixing force, the speed and the range and the number of transfers adjustable. The mixing device comprises a mobile carriage (7) longitudinally movable and fixing elements (8, 9) with an adjustable distance between them. The invention allows for the mixing or emulsifying of blood fluids with different viscosity, particularly a protein gel and a platelet-rich plasma, for the preparation of dermatological formulations, in a versatile, hygienic and effective manner.

A mixer assembly with a static mixing element arranged within a mixing channel. The mixer assembly has an inlet end, for receiving components of a substance and a dispensing end for dispensing a mixture from the components. The inlet end comprises for each component an inlet and an associated non-return valve. Each of the inlets is connectable for fluid communication with the mixing channel via the associated non-return valve.

One aspect relates to a device for mixing two liquids including a tube having an open end, a main line connected to the tube in a liquid-permeable manner, a rubber-elastic body delimiting a line wall of the main line, at least one secondary line in the rubber-elastic body, wherein the at least one secondary line extends from at least one secondary opening up to the main line and opens via at least one mouth into the main line, a main connection for introducing a first liquid into the main line, at least one feed line for introducing a second liquid into the at least one secondary line, which is connected to the at least one secondary opening in a liquid-permeable manner. The at least one secondary line is closed in the rubber-elastic body without the action of a force and is hydraulically openable by a pressure being exerted on a second liquid fed to the at least one secondary line by an elastic deformation of the at least one rubber-elastic body. The open at least one secondary line closes without a pressure being exerted on the supplied second liquid by the restoring force of the elastically deformed rubber-elastic body.

Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.

An apparatus for mixing bone cement for use in orthopedic surgeries includes a mixing region and an agitator for mix the cement ingredients. A temperature sensing means of apparatus determines when that the cement mix can no longer be used. The apparatus can be operated or acted on by a power tool for the mixing of the bone cement. The power tool and/or mixing apparatus may include a mechanical torque limiter that inhibits the agitator as a result of mixing torque exceeding a threshold value. A timer of the apparatus may be started by a sensor of the apparatus or by the user in response to a mechanical torque value. When the timer is complete, a cue by the apparatus signals to the user that the mixed cement is ready and able to be applied.

Systems and methods that implement a GUI functional block that allows a user to specify a compounding formula for a composition, an ingredient validation functional block configured for receiving a code on a container holding a first ingredient, consulting a database to derive a formulation ingredient to be used in preparing the composition, determining if the first ingredient matches the formulation ingredient, a planetary mixer control functional block configured for consulting the database arrangement at least partly on a basis of the specified compounding formula to determine mixing parameters for a planetary mixer that are associated with the specified compounding formula, causing a motor assembly of the planetary mixer to apply superimposed rotation and revolution movements to a container in accordance with the mixing parameters determined from the consulting, preventing operation of the motor assembly if the determining step fails to match the first ingredient to the formulation ingredient.

A disposable fluid transfer and mixing device is disclosed and includes an injector support surface for receiving an injection device thereon. A lyophilized drug vial, a diluent vial and a syringe are also attached to the device. The device features fluid passageways and a manual valve that may be manipulated so that the syringe may be used to transfer diluent from the diluent vial to the lyophilized drug vial, for reconstitution of the drug. The valve may also be configured so that the reconstituted drug is transferred from the lyophilized drug vial to the injection device. An automated transfer and mixing device receives an injection device, a lyophilized drug vial and a diluent vial and transfers diluent from the diluent vial to the lyophilized drug vial and shakes or vibrates the lyophilized drug vial to reconstitute the drug. The device then transfers the reconstituted drug from the lyophilized drug vial to the injection device.

Generation of bubbles is disclosed to occur within a flow of an aqueous fluid. The bubbles may be formed within a tube of a selected diameter and the bubbles are controlled to exit the tube at a selected diameter. Generally, bubbles are formed to include a diameter of less than 1 millimeter, including less than about 20 microns.

A device or system includes a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough. The mixer is in communication with sources or streams of at least two separate components which, when mixed, form a combined fluid stream. The sources or streams may be, at least initially, on opposite sides of the mixer, or the sources or streams may be on the upstream side of the mixer with an outlet disposed downstream of the mixer. A related method may include providing a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough, and selecting a material for the mixer based on physical characteristics of said material, said characteristics including a selected one or more of mean flow pore size, thickness and porosity volume.

A method and system are used to enhance a marker material to include a plurality of air bubbles. The method of manufacturing a marker includes enhancing a marker material to include a plurality of air bubbles using at least a first EFD and a second EFD. The method may include cycling repeatedly through a transfer process between a first container and a second container. A system for enhancing a marker material includes a transfer apparatus configured to receive a marker material and a selected amount of air. The system comprises a first EFD coupled to a first end of the transfer apparatus and a second EFD coupled to a second end of the transfer apparatus.
