    摘要: A stopper is provided, particularly for evacu­ated blood sample tubes, comprised of a combination of thermoplastic and rubber, which combination utilizes plurality of circumferentially spaced joints containing an adhesive. The joints serve to mechanically hold the composite body of rubber and plastic together. The arrangement reduces the quantity of rubber used while retaining its desir­able sealing properties, and reducing the quantity of relatively inexpensive thermoplastic and its desirable strength properties. The invention takes advantage of the relatively good joining properties of a rubber-adhesive combination, and avoids the relatively poor joining properties of a thermo­plastic adhesive combination.

    摘要: The invention relates to a multilayer evacuated blood collection tube (10) comprising: a bottom wall (12), a top edge (16), and a sidewall (14) between the bottom wall (12) and the top edge (16) comprising co-injected inner and outer polymeric skin layers and a polymeric core layer, wherein the core layer is located between and directly adjacent the inner and outer polymeric skin layers, with the polymeric skin layers being non-compatible with the polymeric core layer, wherein the inner and outer polymeric skin layers encapsulate the core layer and the top edge has a cross-section of only the inner and outer skin layers to physically restrain the core layer from delamination from the inner and outer skin layers.

    摘要: A blood collection assembly (10) includes a tube (12), preferably plastic, an elastomeric stopper (14) and a siliceous insert (40) immobilized in the tube (12) under the stopper (14). In a method for taking a blood sample using the assembly, the stopper (74) is punctured and the sample is discharged onto the insert (40) to initiate clotting.
