A method for producing a single-phase phase-stable liquid is provided, in which, in an embodiment: in a first step, a lipophilic liquid is mixed with a hydrophilic liquid, so that a mixture of the liquids is obtained; in a second step, the static pressure of the mixture is brought below the vapor pressure of at least one of the liquids, so that cavitation bubbles occur, for example, as a result of what is known as hard cavitation; and in a third step, the cavitation bubbles are caused to implode, a single-phase phase-stable liquid being obtained.

A storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge having a cylindrical inner chamber, a dispensing plunger that is axially displaceable in the inner chamber of the cartridge, a partition disposed axially in the tubular cartridge, and a cartridge head which closes one end of the tubular cartridge. The cartridge head has a slot-shaped opening, wherein the partition protrudes from the inner chamber of the cartridge through the slot-shaped opening of the cartridge head, wherein the partition divides the cylindrical inner chamber of the cartridge bounded by the dispensing plunger and the cartridge head into two cavities that are spatially separated from one another. A first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity, wherein the partition is removable through the slot-shaped opening of the cartridge head so that the two separate cavities are connected to one another after the partition is removed.

A biological fluid sample analysis cartridge is provided. The cartridge includes a housing, a fluid module, and an analysis chamber. The fluid module includes a sample acquisition port and an initial channel, and is connected to the housing. The initial channel is sized to draw fluid sample by capillary force, and is in fluid communication with the acquisition port. The initial channel is fixedly positioned relative to the acquisition port such that at least a portion of a fluid sample disposed within the acquisition port will draw into the initial channel. The analysis chamber is connected to the housing, and is in fluid communication with the initial channel.

Disclosed is a multi-lumen mixing device that includes a first and second lumen constructed and arranged to separately pass a first and second reagent to a mixing chamber in the device, where the mixing chamber includes a mixing feature that mixes the first and second reagents. The disclosed multi-lumen mixing device may also include a port in fluid communication with the reaction mixing to permit the product of the combined reagents to be injected into a patent.
摘要:
A mixer for mixing a dental composition comprises a mixer housing with a wall of the mixer housing forming a light filter. The light filter provides for substantially blocking light of certain wavelengths, whereas it transmits light of at least some other wavelengths. The invention may help to prevent dental compositions from degrading.

A mixer assembly for a vehicle exhaust system includes a mixer having an upstream end and a downstream end. The mixer defines an internal cavity within which exhaust gases are mixed. A mixer inlet body has an enclosed end and an open end that attaches to the upstream end of the mixer. The mixer inlet body includes an outer peripheral surface extending from the enclosed end to the open end to surround a center axis. The outer peripheral surface includes an inlet port and the enclosed end includes a helically formed portion that initiates a swirling motion to the exhaust gases exiting the inlet port.
摘要:
The present invention relates to a fluid mixer having a fluid inlet (5), a first passage (1) which connects to the fluid inlet, a helical flow passage (2) which connects to the first flow passage, branched flow passages (4) which are branched from the helical flow passage, a second flow passage (3) to which the branched flow passages individually connect, a connection flow passage (7) which connects the first flow passage and the second flow passage, and a fluid outlet (6) which connects to the second flow passage. The branched flow passages are individually branched from different positions in the direction of flow through the helical flow passages. The branched flow passages which are branched from the helical flow passage individually connect to the second flow passage at different positions in the direction of flow through the second flow passage.
