  • Publication number: 20210121620
    Abstract: An extracorporeal blood treatment device comprises a single housing defining an internal blood flow cavity. The housing accommodates an oxygenator, a heat exchanger and an additional mass transfer assembly, each having an array of fluid conduits. The arrays are co-located within the internal blood flow cavity such that blood flowing through the internal blood flow cavity flows substantially homogeneously around all the conduits. The arrays are arranged relative to one another within the internal blood flow cavity such that they together define a continuous blood flow path through the internal blood flow cavity along which blood can flow. The continuous blood flow path has a blood entry surface at one end and a blood exit surface at the opposite end. The overall blood flow direction from the blood entry surface along the blood flow path to the blood exit surface follows substantially a straight line.

  • Publication number: 20200121908
    Abstract: The present invention relates to a connector system for use in connecting conduits together, such as those used with an extracorporeal blood circulation system. The system has a male and female connector and a seal. The seal is operatively associated with the male and female connectors and forms a fluid tight connection between the male and female connectors. An inner surface of the seal and the inner surfaces of the first and second coupling ends form a continuous and smooth transitional surface.

  • Patent number: 10583233
    Abstract: A mechanism for adjusting occlusion of a roller pump is described, wherein the mechanism is provided with: an elongated rod member oriented on a central axis of a pump head of the roller pump; and a drive member attached to the elongated rod member so as to move along the elongated rod member between a first position and a second position, wherein the drive member is connected to each roller block of a pump rotor of the pump head so that movement of the drive member by constant increments along the elongated rod member causes non-uniform and/or non-linear incremental movement of each roller block in a direction radial to the central axis of the pump head.
