摘要： A container has first and second walls, each formed of a thermoplastic sheet having a peripheral edge. A peripheral seal joins the peripheral edges together to form an interior chamber enclosed by the first and second walls. A port communicates with the interior chamber. The port is spaced from and does not extend through the peripheral seal. The port comprises a hollow thermoplastic tube, which extends through a slit in one of the first and second sheets and is oriented tangentially thereto. The slit is fused by heat about the tube, forming a heat fused junction. A medical product or a blood filter material can be housed in the interior chamber.

摘要： A blood filtration device encapsulates a filter pad assembly Within a flexible housing. The filter pad assembly includes first and second filter media layers. A first heat and pressure sealed region integrally bonds the peripheries of the first and second media layers together. The flexible housing comprises a peripheral rim aligned with the first heat and pressure sealed region of the first media layer. A second heat and pressure sealed region, formed after the first heat and pressure sealed region, joins the rim of the flexible housing to the first heat and pressure sealed region, thereby forming a composite seal that encapsulates the filter pad assembly within the housing.

摘要： The method is provided of collecting blood with a donor needle inserted into the vein, which comprises an improvement of: after drawing a desired amount of blood into the blood storage container connected to one end of flexible tubing, occluding flow through said flexible tubing at a point adjacent a flexible, transversely enlarged tubing portion positioned at a location on the tubing spaced from the ends. The flow occluding point is located between the enlarged tubing portion and the container, and the tubing portion is initially of lay-flat type, prior to passing blood through it. One then draws more blood through the needle to enter and fill the enlarged tubing portion. One then occludes flexible tubing between the enlarged tubing portion and the needle prior to withdrawing the needle from the vein of the blood donor.

摘要： Needle covers are provided for medical needle assemblies having a base and a cannula. The needle cover includes hub and cap portions. The hub portion is adapted to be secured to the base. The cap portion is adapted to substantially enclose at least a distal end of the cannula when the hub portion is secured to the base. The cap portion includes at least one generally outwardly extending wing having an outer edge and an enlarged rib extending along only a portion of the outer edge of the wing and only in a direction substantially parallel to a central axis defined by the cap portion. The cap portion is separable from the hub portion upon application of a torsional force, with the rib of the wing being thicker than the portion of the wing radially inward of the outer edge to assist gripping during application of such force.

摘要： Medical needle assemblies incorporating a needle cover are provided. According to one aspect, the needle cover is integrally formed from a material that: (1) is sufficiently rigid to prevent bending of an underlying cannula, (2) is suitable for allowing a frangible portion thereof to be broken under pre-selected conditions, and/or (3) has a moisture vapor transmission rate sufficient for steam sterilization of a needle tip enclosed by the needle cover. According to another aspect, at least part of a cap portion and a hub portion of the needle cover are translucent. According to yet another aspect, the needle cover is provided with a wing having an enlarged rib suitable for gripping during separation of a cap portion from the remainder of the needle cover.

摘要： A method correlates average fiber diameter with performance for a complex filtration media comprising a matrix of fibers having a fibrillated component with a diameter so small (e.g., less than 0.01 microns), that cannot be physically measured with accuracy. The method manufactures a selected matrix, derives the number average diameter of the fibers according to prescribed steps, some of which do not require actual physical measurements, and observes a performance characteristic. The method repeats the foregoing steps for different matrixes, yielding different number average diameters. The method expresses change in the selected performance characteristic as a function of change in number average diameter of the matrices.
