  • Patent number: 6267745
    Abstract: A confined air tube is intended to be placed into in-line communication with the transfer tubing of a blood processing system. The confined air tube provides an incremental volume of air, which keeps the transfer tubing from collapsing and sticking together during heat sterilization. After sterilization, the confined air tube accommodates conveyance of a blood component into an associated downstream transfer container. The confined air tube can also receive air vented from the transfer container, so that the blood component can undergo further processing or be stored in an air-depleted environment within the transfer container.

  • Patent number: 6207107
    Abstract: A steam sterilizable unit for inactivating pathogens in a body fluid is provided including a plastic structure for housing a therapeutically effective amount of a methylene blue solution. The plastic structure preferably includes at least an inner layer constructed from a non-PVC plastic. Preferably, the methylene blue solution has a pH of less than 7.0 and preferably less than or equal to approximately 6.3.

  • Patent number: 6132413
    Abstract: 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.

  • Patent number: 5906915
    Abstract: The present invention provides an improved aqueous solution for suspending and storing red blood cells. The solution includes sodium citrate, a combination of sodium biphosphate and sodium phosphate dibasic, adenine, and mannitol. The solution is formulated at a low osmolarity and has a physiological pH of approximately 7.4. The solution simultaneously maintains stored red cells ATP and 2,3-BPG. Also disclosed is a method for storing red blood cells comprising adding an anticoagulant with a reduced citrate concentration compared to a CPD solution comprising 26.3 g/l, sodium citrate and 3.28 g/l citric acid hydrous to whole blood, separating the red cells and adding a storage solution comprising sodium citrate, sodium diphosphate, sodium phosphate dibasic, adenine and mannitol.

  • Patent number: 5445629
    Abstract: 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.

  • Patent number: 5330464
    Abstract: 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.

  • Patent number: 5270003
    Abstract: A blood sampling system having an in-line sampling member is provided. The member includes a frangible joint located along the length thereof providing an easily openable port for directly sampling a donor's blood during blood collection into a collection bag. In further embodiments, an integral clamping system can be provided with the sampling member for temporarily cutting off flow of blood from a donor.

  • Patent number: 4583971
    Abstract: A sterile, closed drug delivery system (10) is provided comprising a flexible container (12), a capsule (22) coupled to the flexible container and a standard glass drug vial (36) positioned within the capsule. The flexible container has a liquid diluent therein. The capsule has supporting legs (32-35) which extend inwardly from the capsule to support the vial and also a highly flexible, pleated cap (28) which enables the drug vial to be manually moved relative to the supporting legs. The capsule is coupled to the flexible container by means of a hollow spike (54) located within the capsule and a frangible member (58) located within the flexible container, which frangible member allows fluid passage only when it is broken. Manual pressing of the pleated cap moves the drug vial downwardly onto the spike, piercing the stopper of the drug vial. Once the frangible member is broken, there is sterile communication between the drug vial and the liquid diluent contents of the flexible container.
