    摘要: The present invention involves an integrated double-ended needle and blood collection device assembly which is convenient to use, safely contained and ready for disposal after use. The device allows the user to expose and resheath potentially infectious needles without bringing the user's fingers or hands into close proximity with sharp or broken needle tips. After removing the needle from the patient, the needle is safely resheathed by retracting the needle into the device, thereby reducing the risks of accidental needle wounds and infection. The device also serves as a holder for blood collection tubes which can be easily inserted and removed for multiple sampling.

    摘要: A tubular filter element with a rigid, pervious core on which is wound roving in a criss-cross or diamond pattern to provide a variation in density of the wound roving from the interior portion adjacent the core to the outer surface. The change in density is achieved by varying the number of strands of a multi-strand roving during the winding process. In a preferred embodiment, the roving adjacent the core will be composed of three strands, while the roving of the outer portion will have only one strand.
