    摘要: An improved apparatus and method for evaluating platelet functionality of a blood sample. The apparatus includes a plurality of test cells. Each of the cells includes a platelet function restoration agent, an anticoagulant agent, and a clotting reagent. At least one of the cells also includes a platelet activating agent. The clotting time is determined for each of the aliquot portions, and the relative clotting times of the aliquot portions in the cells are determinative of the platelet functionality of the sample. The method includes the steps of combining a platelet function restoration agent, an anticoagulant agent, a platelet activating agent, and the sample of blood to be tested to form a test mixture. The platelets of the sample are activated by adding a clotting reagent to the test mixture at the start of the activated clotting time test, and the activated clotting time test is terminated upon detecting a predetermined change in a property of the test mixture. The activated clotting time of the sample of blood is calculated based on the elapsed time.

    摘要: A ion selective electrode is formed by an electrode having a first membrane with a diffusion rate selective to heparin or other polyions, and a selective polymeric coating thereon having a polyion diffusion rate lower than the polyion diffusion rate of the first membrane. The electrode is sensitive to solutions containing low polyion concentrations such as low heparin concentrations.

    摘要: The present relates to an autologous bioadhesive sealant composition or fibrin glue prepared by a two-phase method, wherein all of the blood components for the bioadhesive sealant are derived from a patient to whom the bioadhesive sealant will be applied. A platelet rich plasma and a platelet poor plasma are formed by centrifuging a quantity of anticoagulated whole blood that was previously drawn from the patient. In one embodiment, the platelet rich plasma is divided into two portions. In phase one, a compound that reverses the effect of the anticoagulant is added to the first portion and a clot is allowed to form. The clot is then triturated, and the resulting serum containing autologous thrombin is collected. In phase two, the serum obtained from phase one is mixed with the second portion of the platelet rich plasma to form the bioadhesive sealant of the present invention.

    摘要: Blood is tested for clot lysis conditions such as natural lytic capabilities, the effect of previously administered thrombolytic and anti-thrombolytic agents, and dose responses thereto, by forming a clot in a sample of blood, lysing the clot, and measuring the elapsed time period from initial clot formation to clot lysis, all while continuously evaluating the blood sample. Thrombolytic agents include streptokinase, urokinase and recombinant tissue plasminogen activator. Plasmin and plasminogen activator inhibitors, clot activating agents (e.g. kaolin), and agents to deactivate anticoagulants (e.g. heparinase) may also be used as reagents during testing.
