  • Patent number: 5873810
    Abstract: An apparatus for centrifuging and furthermore automatically handling a container (10) for separating a component, such as fibrin monomer, from plasma, where the container (10) comprises a cylindrical member (11) with a lower rim as well as a piston member (12) with a tubular piston rod (12) projecting upwardly from the upper end of the cylindrical member (11). The apparatus comprises a supporting turntable (1) with a first gripping member (27) releasably gripping the lower rim of the cylindrical member (11) when the container is placed thereon, the supporting turntable being connected to a first activator (5) for rotating the turntable (1) with the container (10) about the central axis thereof. Furthermore, the apparatus comprises a rotatably journalled piston activating mechanism adapted to activate the piston (12) by way of a second activator (21) and provided with a second gripping member (13) for releasably gripping the piston rod (12).

  • Patent number: 5858253
    Abstract: In a process of separating a liquid sample having phase portions of different densities by centrifugal separation, a phase separator container is employed. The phase separator container comprises a housing having concentric inner and outer cylindrical walls defining a longitudinal axis and a top wall and further a piston body constituting a bottom wall of the housing. The piston body defines together with the outer cylindrical wall, the inner cylindrical wall and the top wall, an annular chamber for receiving the liquid sample. The piston body is displaceable within the annular chamber for draining a phase portion separated from the liquid sample through a drain conduit means communicating with the annular chamber. The phase separation chamber further comprises a reaction chamber to which the phase portions exposed from the annular chamber is processed.

  • Patent number: 5849178
    Abstract: An apparatus is provided for centrifuging and further automatically handling a container (110) for separating a component, such as fibrin monomer, from blood. The container (110) comprises a cylindrical member (27) and a piston displaceable in said cylindrical member, said piston comprising a tubular piston rod (8) extending through a top wall (73). The piston divides the cylindrical member (27) into a first chamber (70) positioned above said piston between said piston and the top wall (73), and a second chamber positioned below said piston. The top wall (73) of the container comprises an extension (90) defining a circumferential slit surrounding the outer side of the piston rod (8), whereby one end of said slit communicates in the axial direction with the first chamber. In addition, the first chamber communicates through a plurality of channels with the second chamber.

  • Patent number: 5830352
    Abstract: A reagent delivery system comprises an axial hub passing through the center of two equal-diameter, spaced apart discs, wherein the hub and discs are positioned in a sleeve such that an annular reagent chamber is provided. When the sleeve is moved in either an up or down axial direction the so-formed chamber is opened and the reagent is released. Such a regent delivery system is particularly useful in a centrifuge for concentrating or preparing blood products.

  • Patent number: 5824230
    Abstract: A method and a device for separating a component, such as fibrin monomer from blood, by centrifugation, involve feeding of blood admixed an anticoagulant to a first annular chamber in a device, where the annular chamber is defined by a cylindrical outer wall and a cylindrical inner wall, both walls extending coaxially about a common axis, as well as by a top wall and a bottom wall. The top wall or the bottom wall is formed by a piston body displaceable within the first chamber. This method involves furthermore a centrifugation of the device about the said common axis to substantially separate blood into a cell fraction and a plasma fraction followed by the resulting plasma fraction being transferred while influenced by the piston body to a second chamber defined by an outer cylindrical wall. The outer cylindrical wall extends coaxially with the said common axis, whereby a fraction with fibrin I is caused to be separated in the second chamber while a suitable enzyme is being added.

  • Patent number: 5795489
    Abstract: A method and a device for separating a component, such as fibrin I from blood, by centrifugation. The method involves feeding of blood admixed an anticlotter to a first annular chamber in a device, where the annular chamber is defined by a cylindrical outer wall and a cylindrical inner wall, both walls extending coaxially about a common axis, as well as by a top wall and a bottom wall, where the top wall or the bottom wall is formed by a piston body displaceable within the first chamber. The method involves furthermore a centrifugation of the device about the said common axis followed by a resulting liquid fraction being transferred while influenced by the piston body to a second chamber defined by an outer cylindrical wall, which extends coaxially with said common axis.

  • Patent number: 5746979
    Abstract: A method of separating fluid into two or more separable fractions. One container section (2) and the adjacent portion of the other container section are made of solid material, and the two container sections are screwed together. The container sections (1 and 2) have their respective chambers (29 and 30) for receiving their respective fluid ingredients, and these chambers are interconnected through a connecting channel (31) through the abutting portions, at which the container sections (1 and 2) are screwed together. A valve seat (21, 27) is shaped at each end of the connecting channel (31) for each valve member (22, 16) for a sealing closing of the chambers (29, 30) in the separated state of the container sections (1, 2).
