  • Patent number: 6077447
    Abstract: A device for producing fibrinogen includes a platen having a surface configured for heat exchange with a container, which is adhered to the platen by device of a vacuum and heat exchange allowing both cooling and heating to occur along the boundary between the container and the platen. The platen is operatively coupled to a device of rocking the platen about a horizontal axis and the container allows scavenging of a cryoprecipitate fibrinogen from the blood product for subsequent utilization.

  • Patent number: 5975367
    Abstract: A fibrin glue dispenser including a spring biased rack. The rack spring is a coil spring having substantially linear characteristics along its operating length. The rack spring forces first and second plungers into first and second loaded syringes to dispense thrombin and fibrinogen into first and second exits such that the admixture of the two occurs for forming fibrin glue away from the exists. A dispensing lever can be controlled as to the fibrin glue formation to dispense either drops of fibrin glue or an elongate line of fibrin glue.

  • Patent number: 5939023
    Abstract: An instrumentality for promulgating the cryoprecipitation of fibrinogen from a blood product. The instrumentality contemplates a container for the blood product, an apparatus for creating the fibrinogen within the container and a method of manipulating the container within the apparatus and subsequently after fibrinogen has been formed. The apparatus includes a receiver within which the container is supported, a motion transfer device for the receiver to impart motion to the container while simultaneously subjecting the container to a temperature differential to cause heat transfer. The motion imparted to the container results in a thin coating of the blood product being disposed on an interior surface of the container which, in turn, is exposed to a heat transfer fluid through the wall of the container. Successive coatings placed on an interior of the container are timed such that each coating is placed on a previous coating that has changed phase.

  • Patent number: 5759171
    Abstract: A sprayer for dispensing fibrinogen and thrombin to form fibrin glue immediately away from the sprayer to prevent clogging and insure accurate precise metering. The sprayer includes a pistol grip area, a barrel and a trigger which moves a plunger support that captures the plunger of a syringe. One syringe holds thrombin and the other syringe holds fibrinogen. Each syringe communicates with an outlet having an atomizer.

  • Patent number: 5557943
    Abstract: Rapid cooling or freezing of foodstuffs, perishables or blood products is accomplished by using a thin film membrane to totally envelope the foodstuffs or blood product only during the heat extraction period. This thin film encapsulation system closes around the item and is held tightly to the item by atmospheric and/or hydrostatic pressure. Once the item is encapsulated, low temperature heat transfer fluids are then circulated on the exterior surface of the membrane, thus extracting the heat within the item through the thickness of the membrane. Upon completion of the necessary chilling or freezing, the atmospheric and/or hydrostatic pressure is withdrawn and the chilled or frozen item is extracted.

  • Patent number: 5261255
    Abstract: A method and device for fractionating pouches of cryoprecipitable material including a membrane which provides a barrier within an interior of the device with the membrane receiving the pouches of cryoprecipitable material therewithin. The interior of the device includes a sump having a heat transfer fluid stored therein and maintained at a temperature which is to be achieved by the cryoprecipitable material as it cycles between freezing and thawing. The pouch of material, after placement within the membrane, is exposed (through the membrane) to hydrostatic forces associated with the heat transfer fluid in the sump collapsing the membrane on the pouch while pulsating jets impinge indirectly upon the pouch through the membrane. In this way, as the contents within the pouch change temperature, circulation of the fluid within the pouch occurs for more rapid realization of the cycling target temperatures for the cryoprecipitable material within the pouch.

  • Patent number: 5243833
    Abstract: A method and device for thawing pouches of frozen transfusion material including a membrane which provides a barrier within an interior of the device with the membrane receiving the pouches of frozen material therewithin. The interior of the device includes a sump having thawing fluid stored therein and maintained at a constant target temperature which is to be achieved by the frozen transfusion material to be thawed. The pouch of material to be thawed, after placement within the membrane, is exposed (through the membrane) to hydrostatic forces associated with the fluid in the sump collapsing the membrane on the pouch while pulsating jets impinge indirectly upon the pouch through the membrane. In this way, as the contents within the pouch thaw, circulation of the fluid within the pouch occurs for more rapid realization of the target temperature for the fluid within the pouch.

  • Patent number: 5103651
    Abstract: A thermal transport device having a hollow within which a plasma storage freezer is deployed. The freezer acts as a cold "battery" by having a eutectic fluid contained therewithin. The freezer is placed in a commercial, powered refrigeration unit for chilling ("charging") the eutectic fluid of the plasma storage freezer to approximately -30.degree. C. The freezer is then deployed within the thermal transport device and sent to a remote locale for collecting blood plasma. Blood plasma is disposed between a central heat sink and lateral heat sinks of the freezer freezing the blood plasma quickly and maintaininig its initial high quality because of negligible time loss for freezing. Ultimately, the device is returned to a commercial powered refrigeration unit for ("recharging") rechilling the eutectic fluid for subsequent reuse.

  • Patent number: 4730460
    Abstract: Ultra rapid freezing of thin wall containers, preferably plastic bags or bottles, of blood plasma by direct contact with a low freezing temperature liquid mixture of a chlorofluorocarbon (CFC 113) and at least one of a group of fluorocarbons minimizes migration of toxins in the heat transfer liquid to the plasma and improves the percentage yield of blood soluble protein fractions extracted from the frozen plasma in a subsequent freeze drying process.
