    摘要: A frangible seal for a fluid path including a frangible seal member secured within a tube defining the fluid path. The frangible seal member having a tubular seal member and a stem extending from the tubular seal member which, upon bending back and forth, breaks away from the seal member thereby to rupture the tubular seal in the fluid path. The tubular seal member and stem are integrally formed of a non-PVC material. The tubular seal member will bond to PVC tubing during steam heating thereof. The tubular seal member and stem are constructed to provide uniform non-reclosable rupturing. The stem includes vanes with spurs that frictionally engage the inner walls of the tube to maintain separation of the stem and ruptured tubular seal member.

    摘要: A container for housing body fluids. The container comprises a body defined by flexible walls having an interior for housing the body fluid. An elongated tube extends from the body for housing a fluid to be added to the body fluid. The tube includes means for allowing selective fluid flow from the interior of the tube to the interior of the body allowing the fluid to be added to the body fluid. Additionally, the means for allowing selective fluid flow allows the body fluid to be expressed from the body of the container into the elongated tube. The present invention also provides a method for storing and treating blood.

    摘要: A breakable seal is located within a housing. The housing includes a ribbed region of restricted diameter protruding from the wall into the bore. A breakable juncture in the seal joins the tip of a cannula member to the base of the cannula member. The leading portion of the tip is free of any projection that frictionally engages either the wall or the ribbed region. Thus, neither the wall nor the ribbed region contacts or constrains movement of the leading portion in the bore when the tip is broken from the base. The trailing portion of the tip carries at least one projection constructed to frictionally engage the ribbed region. The ribbed region constrains movement of the trailing portion through the bore when the tip is broken from the base. By rocking the cannula tip, the juncture can be broken and the cannula tip advanced to a secure position in the housing.
