Embodiments of the present invention provide a hollow cylindrical filter for removing efficiently foreign substances from fluids. This is performed by forming complicated passages including an axial direction and a radial direction in the filter. The hollow cylindrical filter is formed by winding a metal wire rod in a spiral and multilayered manner. The metal wire rod includes a recess formed throughout the entire length in a longitudinal direction, or recesses repeated along said longitudinal direction. Some wire rod layers extend in an axial direction of the hollow cylindrical filter while the adjacent wire rod layers extend in an intersecting direction, thereby forming a plurality of communication paths for communicating between the overlapping wire rod layers. Additionally, a space is formed between the recess of one wire rod layer and another adjacent wire rod layer, allowing the plurality of communication paths to communicate with each other.

Filter media incorporating one or more filtration layers that include fibers including fiber portions orientated at a non-zero angle with respect to a surface of the filtration layer are provided. In some embodiments, at least a part of the fiber portions are positioned at an angle of at least 20 degrees (e.g., between 46 degrees and 90 degrees, or between 61 degrees and 90 degrees) with respect to a surface of the filtration layer or an outer or cover layer of the media. This orientation of fiber portions may result in an increased efficiency (e.g., average efficiency and/or initial efficiency) compared to similar filter media that do not include such oriented fiber portions.

A tubing set for a blood processing system includes a first connector, a first tube, and a second tube. The first connector is configured to connect to a separation device within the blood processing system, and has a first inlet configured to be fluidly connected to an outlet of the separation device. The first connector also has an outlet and a second inlet. The first tube fluidly connects to the outlet and fluidly connects the separation device and a blood component storage container. The second tube is fluidly connected to the second inlet and fluidly connects the separation device and a saline storage container. The second tube may include a second connector that connects to the saline storage container.

A two-stage dust-air separation structure includes a cyclone separator and a spiral dust-air separation device. A first stage separation of dust from air is realized by a cyclone housing, and by arranging a second-stage cyclone barrel 5 inside the cyclone housing and arranging the spiral dust-air separation device at a barrel opening of the second-stage cyclone barrel, the dusty air, after going through the first stage separation, is guided by the spiral dust-air separation device to form, on an inner wall of the second-stage cyclone barrel, an airflow rotating towards the barrel bottom, and the dust in the airflow is driven by a centrifugal force to rotate downwardly to the barrel bottom and be collected in a second-stage dust collecting space, and the air in the rotating airflow is extracted by the negative pressure, thereby realizing a second stage separation of dust from air.

The present invention generally relates to the field of pharmaceutical sciences. More specifically, the present invention includes apparatus and devices for the preparation of pharmaceutical formulations containing large diameter synthetic membrane vesicles, such as multivesicular liposomes, methods for preparing such formulations, and the use of specific formulations for therapeutic treatment of subjects in need thereof. Formation and use of the pharmaceutical formulations containing large diameter synthetic membrane vesicles produced by using the apparatus and devices for therapeutic treatment of subjects in need thereof is also contemplated.

A device for filtering a flow of gas conveying liquid or solid particles in a flow channel. According to the invention, the particles are imparted a speed that is high enough to project same by inertia into the opening of a recovery channel formed inside the flow channel, while the gas from the flow bypasses said opening due to a specific configuration of the flow conditions of a perfect fluid in the flow channel and in the collection channel.

Disclosed is composite media that may be utilized in coalescing elements, coalescing cartridges, coalescing systems, and coalescing methods. The disclosed media typically is a composite or laminate material formed by bonding adjacent layer of media material comprising bicomponent fibers.

A filter having a plurality of filter pores penetrating one surface and another surface of the filter, wherein the filter pore has a first opening on the one surface and a second opening on the another surface, a ratio (L1/W1) of a major axis diameter L1 to a minor axis diameter W1 of the first opening is 1.00 or more and 1.20 or less, the minor axis diameter W1 is 7.0 ?m or more and 9.0 ?m or less, a ratio (L2/W2) of a major axis diameter L2 to a minor axis diameter W2 of the second opening is 1.00 or more and 1.20 or less, and a ratio (W2/W1) of the minor axis diameter W2 to the minor axis diameter W1 and a ratio (L2/L1) of the major axis diameter L2 to the major axis diameter L1 are both 1.20 or more and 1.50 or less.
