Abstract: A method for forming a disposable non-latex tourniquet from a thermoplastic elastomer and an additive comprising slip and anti-block components.

Abstract: A vessel useful for the collection of body fluid samples includes a first elongate tube defining an axis. The first tube has an open end with an inside diameter and a closed end section with an outside diameter. The first tube includes a receptacle therein for receiving a fluid sample that is accessible from open end. The vessel includes a second elongate tubes substantially identical to the first tube. The closed end section outside diameter is less than the inside diameter of the open end. The first tube closed end section is conjugately disposed in the open end of the second tube so that the first tube and the second tube are substantially axially aligned thereby forming a single article.

Abstract: A medical article of a polymeric nonthermoplastic material and method therefor is made by a continuous compression molding method in which a predetermined quantity of the polymer is added sequentially to a series of molds on a track.

Abstract: A disposable non-latex tourniquet formed from a thermoplastic elastomer and an additive comprising slip and anti-block components. More particularly, the disposable non-latex tourniquet is formed from a metallocene octene based polymer and an additive comprising slip and anti-block components. The disposable non-latex of the present invention substantially minimizes discomfort to the patient and facilitates ease of use in knotting and releasing the tourniquet from the patient.

Abstract: A blood collection assembly includes a plasma-treated blood collection container and a blood collector which optionally may also be plasma-treated. The collector has a body portion providing a blood passageway between the container and a scoop shaped portion which contacts a puncture wound. A vent in the collector allows air displacement from the container when blood enters. The inside wall of the container has longitudinal ribs molded thereon and an altered surface chemistry characterized by an enhanced oxygen content. The invention includes a method to increase blood flow across the interior surface of a plastic blood collection container comprising plasma treatment of the surface.

Abstract: An arrangement is provided for inducing rapid flow of a blood sample into a collection assembly for the sample, with the arrangement including an elongated member of narrow width positioned in the flow path of the blood from the source therefore to the collection area therefore. The member of the invention may be, for example, an elongated flat strip, flexible or rigid, a solid rod, a solid strip square in cross section, or a tubular rod. The elongated device may be separate and positioned or adhered to a surface forming the blood flow path or it may be molded simultaneously with a collection assembly. The device may serve to provide a bridging transition from the surface of one part of an assembly to another. Finally, the device may be used to induce sample flow back and forth in a collection tube during mixing.

Abstract: A blood microcollection container and associated lancet-collection assembly is provided for making a puncture wound, engaging the wound and rapidly receiving blood from the wound. The assembly incorporates a lancet together with a scoop arrangement for engaging the blood source, and for directing in a rapid and efficient manner the blood to a collection chamber. A two-position cap is provided for sealing the scoop collector of the assembly prior to use, and for permanently locking to the collector after use to prevent exposure of the lancet and collector to the person handling the blood sample, or contamination of the blood sample from outside sources.

Abstract: A microsyringe includes an elongated hollow tube having no piston, plunger or the like positioned in its lumen. A needle cannula is at one end of the tube in fluid communication with the lumen. A connector hub is at the other end of the tube for attachment to a device for providing a fluid movement force into the lumen.
