The instant disclosure is directed to a heterogeneous fiber fluid reservoir for holding and delivering fluid. A reservoir may comprise a rod having a core component and a surrounding component. Each of the core component and the surrounding component may comprise fibers. The core component may have a first property, and the surrounding component may have a second property different from the first property, or the core component and the surrounding component may each have a different value or range of values for the same property. Alternatively, a reservoir may comprise a rod that includes fibers and has a cross-sectional diameter. At least one property of the rod may vary in value along the cross-sectional diameter of the rod. The property may include, for example, fiber bulk density, fiber diameter, fiber material, fiber morphology, fiber surface tension, capillary force, fluid absorption capacity, color, or combinations thereof.

Heterogeneous fiber fluid reservoirs

The present disclosure provides small diameter tubular porous fiber filters. These tubular porous fiber filters have many uses including but not limited a filtration medium for removing particles of 5 microns or less from liquid or air.

Small diameter tubular porous fiber filter

The present invention provides infusion devices, such as intravascular (IV) devices, comprising a hydrophilic sintered porous plastic filter or a hydrophilic porous fiber filter which are effective at stopping or greatly reducing transmission of air through the filter.

Infusion device with a hydrophilic sintered porous plastic or hydrophilic porous fiber air stop filter

An improved biological sample preparation device and method of using the device, the device including a squeezable tube and a tip assembled to the squeezable tube. The tip includes a filter and a wick configured to enable controlled delivery to a diagnostic device by capillary action. The device provides precise and repeatable sample volume dispensing control, reduces potential contamination in the working environment, increases ease of use, and improves safety for healthcare workers.

Squeezable sample preparation device

The present application provides devices and methods of making and using these devices. The devices comprise a sintered porous polymeric material, a porous membrane attached to at least a portion of the sintered porous polymeric material, and optionally a housing which surrounds at least a portion of the sintered porous polymeric material. The devices can be used for sample collection, purification and transfer.

Membrane-coated sintered porous media for sample collection

The instant disclosure relates to an integral porous fiber media with distinguishable distribution of fiber density, fiber diameter and capillary force. The instant disclosure further relates to a fiber porous media that includes multiple density portions. The disclosed media is a single piece, such that the different density portions are not separable. The disclosed media provides improved liquid delivery properties for a specific liquid delivery device.

Integral porous fiber media with distinguishable density or fiber diameters

The present invention provides a porous non mechanical valve which retards or prevents the passage of bodily fluids and is resistant to being occluded or blocked by exposure to the surgical fumes or aerosols encountered during surgical procedures.

Hydrophobic porous non mechanical valve for medical suction device

The present invention provides a liquid sampling, storage, transfer and delivery device comprising housing containing a porous nib. The porous nib in the device contacts the sample, collects the sample, stores the sample, transports the sample inside its porous matrix and releases the sample from the porous matrix upon demand.

Liquid sampling, storage, transfer and delivery device

The present application provides a device and methods of making and using these devices. The devices comprise porous caps and porous vents made from sintered porous polymeric media comprising plastic particles, elastomeric particles or a combination thereof. These devices are used with medical devices or components thereof to provide ease of use, resistance to infection, sterilization and venting.

Sintered porous polymeric caps and vents for components of medical devices

This application discloses porous self-sealing media comprising a sintered mixture of an absorbent material and a thermoplastic. The self-sealing media block passage of organic solvents or organic solvents in aqueous mixtures, wherein the organic solvents are at concentrations greater than about 40%. The self-sealing media also block acidic solutions. The self-sealing media are useful in a variety of applications such as a pipette tip filter, in line filter, vent, non-mechanical check valve, safety valve, and suction canister.

Sintered porous plastic liquid barrier media and applications thereof

The present invention provides sintered porous plastic plugs for use in filtered serological pipettes which facilitate manufacture or assembly of the filtered serological pipettes. In one embodiment, a sintered porous plastic plug of the present invention comprises plastic and a cylindrical body, a first end and a second end, the first end having a cross-sectional area less than the cross-sectional area of the cylindrical body, and the second end having a cross-sectional area less than the cross-sectional area of the cylindrical body.

Sintered porous plastic plug for serological pipette

This application discloses cards comprising sintered porous plastic which may be employed in liquid sample collection, storage, transport and/or delivery to an analytical device. Sintered porous plastic materials provide a unique porous structure, an inert substrate, precise liquid holding capability, are quick drying, and easy to cut and handle.
