A mixing device, in particular for bone cement, in which at least two ampoules provided with a septum are pushed onto needles, in parallel to each other, for discharging the liquid.

A storage and mixing system, for pasty two-component polymethyl methacrylate bone cements, comprises a cartridge with a cylindrical interior, a cartridge head that closes an end of said cartridge, a partition wall axially disposed in the cylindrical interior of the cartridge, wherein said partition wall is connected to the circumferential surface of the cylindrical interior of the cartridge and divides the cylindrical interior of the cartridge delimited by the cartridge head into two spatially separate cavities. The first cavity includes a first pasty cement component and the separate second cavity includes a second pasty cement component, two delivery plungers close the two cavities on the side of the cavities opposite the cartridge head. At least two cutting edges are disposed on the front side of the sleeve-shaped connecting means facing the cartridge head, such that the at least two cutting edges cut off the partition wall from the cylindrical inner wall of the cartridge as at least one cut-off strip when the delivery plungers are advanced towards the cartridge head in the cavities with the connecting means, and wherein the sleeve-shaped connecting means comprises a deflecting surface which is inclined to the axis of the connecting means which, on advancing the connecting means, presses the at least one cut-off strip of the partition wall towards the inner wall of the cartridge.

A storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge with a cylindrical interior, a cartridge head that closes one end of the tubular cartridge, a partition wall axially disposed in the cylindrical interior and dividing the cylindrical interior into two spatially separate cavities, the first cavity including a first pasty cement component and the second cavity including a second pasty cement component, two delivery plungers disposed movably in the two cavities and connected via a connecting means, wherein a wedge or cone having a cutting edge on the front side thereof facing the cartridge head is disposed on the connecting means, such that said cutting edge cuts open the partition wall when the delivery pistons are advanced towards the cartridge head and the wedge or cone presses the cut open parts of the partition wall towards the inner wall of the cartridge.

A powder transfer bag includes a balloon or a membrane sealing its mouth. A connector to be used with the bags allows the bag to connect to a hydration device. A method of hydrating material in a powder transfer bag is provided.

The disclosed bag for mixing materials may include a front wall, a back wall, a mixing chamber between the front wall and the back wall, a first sidewall between the front wall and the back wall and defining a first side of the mixing chamber, a second sidewall between the front wall and the back wall defining a second, opposite side of the mixing chamber, and a port positioned to provide fluid access to the mixing chamber from a bottom of the mixing chamber, wherein the first sidewall and the second sidewall are shaped to alternate a direction of fluid flow when fluid is introduced into the mixing chamber through the port. Various other components, systems, and methods are also disclosed.

A drug mixing container is provided. The drug mixing container includes a container with an opening facing upward and a cover body. An inner peripheral wall of the container includes at least one piercing structure protruding toward the opening of the container. The cover body accommodates a drug and includes a sealing film for sealing the drug in the cover body. In use, when an opening of the cover body is coupled downward to the opening of the container, the sealing film is pierced and torn by the piercing structure to make the drug in the cover body flow into the container, thereby preventing hands of an operator from being stained with the drug.

A liquid concentrate generation system may comprise a manifold having an inlet receptacle including a first piercing member, an outlet receptacle including a second piercing member, and a flow channel connecting the inlet receptacle and outlet receptacle. The system may further comprise a cartridge having an inlet port and an outlet port sealed by a respective first and second cover. The inlet and outlet port may be respectively configured to displace within the inlet receptacle and outlet receptacle from an unspiked position to a spiked position. First and second piercing members may be in communication with the flow channel and spaced apart respectively from the first and second cover in the unspiked position. The first and second piercing members may be isolated from the flow channel and may respectively puncture the first and second cover in the spiked position.

A dissolving and mixing unit for automatically dissolving and mixing medicines includes: a support; a dissolving and mixing device mounted on the support and including two piercer bases and at least one dissolving and mixing channel, wherein each dissolving and mixing channel includes two piercers and an elastic infusion hose connecting the two piercers, and the two piercers of each dissolving and mixing channel are mounted on the two piercer bases respectively; a peristaltic pump mounted on the support and configured to squeeze the elastic infusion hose; first and second bottle-containing modules mounted on the support and configured to hold first and second medicine containers respectively; and a movement mechanism configured to drive at least one of the first bottle-containing module and one piercer base to move, and configured to drive at least one of the second bottle-containing module and the other piercer base to move.

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.

The invention relates to a metering container for mixtures of food products and liquids, a metering device for mixtures of food products and liquids and a method for metering mixtures of food products and liquids.
