    摘要： An apparatus for separating blood is provided with a closed end and a thixotropic gel-like sealant with a specific gravity intermediate between the gravities of serum and clot phases. A cavity is formed on the upper surface of said sealant. The sealant consists essentially of an .alpha.-olefin-dimaleate copolymer having a viscosity from 10,000 to 120,000 c.p. (25.degree. C.), to which a viscosity-specific gravity adjusting agent is added to adjust the specific gravity to 1.035-1.055. The cavity is formed in such a size that diameter of the upper surface is from 0.15 to 0.7 times the inner diameter of the apparatus and its depth is from 0.13 to 0.65 times the thickness of said sealant.

    摘要： A blood collector comprising a collection container in the form of a tube having a forward end adapted for drawing of blood into the container and an opened rear end, a closure unit adapted for closing the opened rear end of the collection container, and a mechanism including a valving element for allowing passage of air when blood is flowing into said container and preventing passage of air and blood when said container is filled with blood, said valving element of said mechanism including an air passage and a filter member communicating with the air passage, said filter member comprising water insoluble but water-swellable polymeric material and provided at least at the contact portion of the closure member with collected blood. Air contained in the blood collecting space of the collection container is expelled through the valving element by the collected blood which rises to a desired level for expelling air from said space practically completely. As the blood contacts the water insoluble but water-swellable high polymeric material contained in filter member of the valving element, the material swells into gel body to block the air passage in the valving element connecting to outside of the collector. Thus blood analysis may be effected without influences by outside air and air otherwise contained in the blood collecting space.

    摘要翻译： 一种血液收集器，包括管形式的收集容器，其具有用于将血液吸入容器的前端和敞开的后端，适于封闭收集容器的打开的后端的封闭单元，以及包括 用于当血液流入所述容器时允许空气通过的阀元件，并且当所述容器充满血液时防止空气和血液通过，所述机构的阀元件包括空气通道和与空气通道连通的过滤器构件， 所述过滤器构件包括水不溶性但水可溶胀的聚合物材料，并且至少在封闭构件的接触部分处提供收集的血液。 包含在收集容器的血液收集空间中的空气被收集的血液通过阀元件排出，其升高到期望的水平，从而实际上完全从所述空间排出空气。 当血液接触包含在阀元件的过滤器构件中的不溶于水但可水膨胀的高聚物材料时，材料溶胀到凝胶体中以阻挡连接到收集器外部的阀元件中的空气通道。 因此，血液分析可以在不受外部空气和空气的影响的情况下进行，而外部空气和空气不包含在血液收集空间中。

    摘要： A syringe includes an outer cylinder, a gasket having at least one part which slidably contacts the inner wall of the cylinder and being made of an elastomer material including a block copolymer having styrene units at both terminal ends, and means for sliding the gasket inside the cylinder. The slidably contacting part is compressed inside the cylinder at a compressiblity C (%) of a predetermined range selected according to a particular inner diameter of the cylinder. The product of the total contact area S (mm.sup.2) at the compressibility C (%) of the contacting part with the inner wall of the cylinder with the compressibility C (%) is about 350 to about 900.
