摘要:
The present disclosure is directed to a method of preparing an osteogenic bone graft. The method includes introducing an anticoagulant compound into a volume of cellular material including a mononuclear cell population from the intramedullary canal of a long bone; collecting an effluent including the volume of cellular material containing the anticoagulant compound at a collection point; separating a concentrated cell fraction from the effluent, the concentrated cell fraction including the mononuclear cell population and the anticoagulant compound; and preparing an osteogenic bone graft from the concentrated cell fraction.
摘要:
A device for separating and isolating components of a biological fluid comprising a container for containing the fluid to be processed, a tube cap assembly for closing the container while providing filling and extraction communication therewith, a float assembly disposed within the container for funneling and controlling biological fluid flow into an inverted domed shaped isolation chamber within the float and controlling the biological fluid flow out of the isolation chamber for effecting an encapsulation or a sealed isolation of at least one component or fraction of the biological fluid flow within the isolation chamber during a centrifugation process. The device further comprising a flexible tube for connecting an extraction passageway disposed within the float assembly and an extraction valve of the tube cap assembly for allowing extraction of at least the one component or fraction encapsulated or isolated within the chamber.
摘要:
An apparatus and method for collecting whole blood and then separating it into components for subsequent use or storage. A self-contained bag set is used to collect the sample, which may then be placed into a device adapted to fit into a centrifuge for separation of components. Each component is then sequentially extracted according to density, with a sensor present in the device to control the operation of valves directing the collection of each component. The sensor may be reading one or more of the following characteristics: infrared, optics, density, weight, radioactive, fluorescence, color, magnetism, ultrasonic, capacitance wherein the characteristic is inherent in the blood and blood component or is an additive. Each component may then be separated into its own storage container. The preferred sensors include optics and weight. Besides blood density separation, the device may contain a solution including cells, proteins, subcellular particles or viruses which may be mixed with affinity media or antibodies prior to separation.
摘要:
A mold is disclosed for forming a freezable and thawable bag of uniform thickness, especially useful for cryopreservation of thermolabile substances. The mold features one or more recessed planar surfaces, including radiused peripheral walls about the recesses, a planar top surface, and means for conforming a blank sheet to the mold. Two mold halves combine to form a completed bag. The mold halves may be complimentary.
摘要:
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.

摘要:
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.
摘要:
A device for cryoprotecting thermolabile products. A container (20) receives an annular rack (40) which is sealed by an enclosure (60). The enclosure (60) includes an outer stationary toroid (70) and a rotatable core (90). A robotic arm (160) is adapted to move and is supported by the core (90). The robotic arm (160) accesses an interior of the enclosure (60). An access portal (80) allows removal and placement of thermolabile products constrained by a holder (150). The robotic arm (160) accesses product and holder (150) and embarks upon controlled freezing of the product and its location in the rack (40) until subsequent retrieval. A computer controls the rate of freezing and stores in memory the location of all of the stored products. The robotic arm (160) reads the product in storage to assure the correct product is being accessed.
