  • Patent number: 10124105
    Abstract: A device (1) for the extracorporeal oxygenation of the blood of a patient, comprising a containment casing (2) which has at least an inlet port (4) of the venous blood and at least an outlet port (5) of the arterial blood, at least an inlet channel (6) and at least an outlet channel (7) of a work gas intended to provide oxygen to blood and/or to remove CO2 from the same, at least a bundle of hollow fibers (8) arranged within the casing (2) and placed between the inlet channel (6) and the outlet channel (7), the hollow fibers being in communication with the inlet and outlet channels (6, 7) and being intended to be crossed by the relative work gas, at least a first and at least a second filtering elements (12, 13) arranged inside the bundle of hollow fibers (8) and spaced apart the one from the other, the filtering elements (12, 13) being able to trap any air bubbles present in the treated blood, where the first and second filtering elements (12, 13) define a relative open profile and where the hollow fibers (8

  • Patent number: 8066942
    Abstract: An integrated device for heating and oxygenating blood in an extracorporeal blood circuit, comprising a shell-and-tube heat exchanger module provided with a coupling to a blood supply line and with two couplings respectively for the intake and discharge of the water designed to exchange heat with the blood; ports are also provided for the passage of the blood toward an oxygenator module of the hollow-fiber type which is located at the peripheral region of the heat exchanger and is provided with a coupling to a blood discharge line; the device further comprises means adapted to direct the flow of blood along a turbulence-free path and with optimum distribution within the two modules.

  • Patent number: 8052632
    Abstract: A cardiotomy reservoir, comprising an outer wall provided, at the lid, with connectors for the inflow of blood to be filtered and, at the bottom, with a connector for the outflow of the filtered blood, a filtering mass being provided which divides the space delimited by the outer wall into a portion that is connected to the inflow connectors and a portion that is connected to the outflow connector; the cardiotomy reservoir comprises a layer of material adapted to retain fats present in blood, and further comprises a first partition and a second partition, which are adapted to delimit at different distances the region that comprises the blood outflow connector and are provided with ports for the passage of the blood in its path for accessing the connector which are arranged at differentiated levels with respect to the bottom, the ports that are provided in the first partition that lies closest to the outflow connector being located at a height, from the bottom, that is greater than the height of the ports prov

  • Patent number: 7748438
    Abstract: A heat exchanger for medical use, comprising a tube bundle formed by a plurality of tubes having a straight axis for the conveyance of a primary fluid, which are embedded at their ends in disks located at the end faces of an outer jacket which is adapted to delimit, together with the disks, a portion of space for the containment of the tube bundle which is designed to be crossed by a secondary fluid, each tube having, at least at a portion of its length, a plurality of consecutive crimps adapted to determine a progressive variation of the shape of the passage section.

  • Patent number: 7666159
    Abstract: A venous reservoir in an extracorporeal blood circuit, comprising a rigid outer enclosure for a filtering mass in the form of a hollow cylinder, provided with an upper lid which comprises couplings for the inflow of blood with the portion of space delimited by the filtering mass and with a connector at the bottom, the reservoir further comprising a diaphragm which is arranged below the upper lid and is adapted to receive the blood that enters through the couplings provided in the peripheral region of the lid, at the axis of a central hole of the diaphragm there is a column with longitudinal vanes which protrude upwardly until they skim the rim of the hole and are adapted to follow the blood in its flow by gravity toward the collection region at the base of the enclosure.
