In drug mixing devices of disclosed embodiments, a main flow path extending from one end configured to allow liquid inside the first container to enter the main flow path therethrough to another end configured to allow liquid inside the second container to enter the main flow path therethrough, and a branch flow path branching from the main flow path are formed. The drug mixing device includes a body including a first connection part configured to be coupled with the first container and a second connection part configured to be coupled with the second container, and a backflow prevention part disposed in a partial flow path of the main flow path extending to the one end with reference to the connection point of the main flow path and the branch flow path, the backflow prevention part being configured to prevent liquid from flowing from the connection point to the one end.

A positive displacement mixer and method for mixing a product that mixes at least two materials into a homogenous product. The positive displacement mixer has at least one positive displacement element having a length, a primary compartment, and a moving element, and two or more minor positive displacement elements each having a length, a minor compartment, and a moving element. The primary compartment and the minor compartments are fluidly connected and during mixing the primary compartment and minor compartments are closed to the atmosphere.

Provided herein are apparatuses and systems for mixing liquids and suspensions that include vessels with structures that improve mixing while not contacting liquid delivery components. The apparatuses and systems can include a motor drive that allows speed and directional control of rotation of the vessel. The apparatuses and systems can include one or more magnets for separating magnetic beads in a suspension. Also provided are methods using said apparatuses and systems for mixing and separation processes.

A capsule for mixing multiple substances, comprising: a main chamber having a main chamber bottom and a main chamber top, the main chamber top having a top opening; a main piston fitted in the main chamber; a torque adapter for transferring a torque from an external actuator to a mixer element via the main chamber bottom; and a cup shaped reservoir having a reservoir bottom which is having a bottom opening, wherein the reservoir bottom is fixated to the main chamber top such that the bottom opening is aligned with the top opening of the main chamber, so that fluid pushed by the main piston from the main chamber is passed through the top opening and the bottom opening and is accumulated in the cup shaped reservoir.

A capsule for mixing multiple substances, comprising: a main chamber having a main chamber bottom and a main chamber top opening; at least two repository tubular chambers, each: adapted to contain substance, mechanically connected to the main chamber and having a repository tubular chamber top opening; at least two passages, each fluidly connecting one of the at least two repository tubular chambers to the main chamber; a main piston fitted in the main chamber; and a mixer rod having a mixer element disposed at a distal end and a torque adapter disposed at a proximal end for transferring a torque to the mixer element, the mixer rod is fitted to pass along the main piston such that the mixer element is mounted in the main chamber between the main chamber bottom and a distal end of the main piston when the main piston is in the outward position.

Described is an automated reagent mixing container for separately storing and automatically mixing together at least two stored reagent components.

A system is disclosed including at least one scanner identifying an identification associated with a receptacle. At least one dispenser is configured to dispense a first desired amount. At least one dispensing area has a measuring instrument that measures a dispensed amount and an unused amount, and associates with the identification. At least one storage device stores a program, and at least one controller which, when executing the program, is configured to receive information and associate the information with the identification. Collected data associated with the identification is recorded. A second desired amount based on at least some of the collected data in at least one file in the database is recommended. The at least one dispenser is controlled by the at least one controller based on the first desired amount or the second desired amount. The at least one dispenser is configured to dispense the second desired amount.

One aspect relates to a method for providing a bone cement from two starting components, having a hollow cylinder-shaped first container, in which a monomer liquid as first starting component can be stored, a hollow cylinder-shaped second container comprising a container wall, a first internal space, and a second internal space, whereby a bone cement powder as second starting component can be stored in the first internal space, and whereby the monomer liquid can be conveyed into the second internal space, a fluid-conducting conveying means arranged between the first internal space and the second internal space, whereby the first container and the second container are axially connected to each other.

A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.
