OXYGENATOR
An oxygenator apparatus for use in an extracorporeal circuit. The apparatus includes a housing and a membrane assembly disposed within the housing. The membrane assembly includes a first plurality of gas exchange elements disposed in a first zone and a second plurality of gas exchange elements disposed in a second zone. The second zone is arranged concentrically around the first zone. The first and second plurality of gas exchange elements are fluidly open along a body and fluidly separated along a distal end. The first zone is configured to be fluidly coupled to an oxygen source and the second zone is configured to be fluidly coupled to a negative pressure source. A blood flow path includes a generally radial flow through the first zone to add oxygen to the blood and the second zone to separate gaseous micro emboli from the blood through the plurality of gas exchange elements.
FIBER MEMBRANE TUBE FOR MASS TRANSFER BETWEEN FLUIDS AND METHOD OF AND CORE WINDER FOR MAKING SAME
The invention relates to a method for producing a device for a mass transfer between two fluids, wherein at least one hollow-fiber mat (9) is wound on an at least partly hollow core assembly (1, 1a, 1b, 2), and the formed coil is inserted into a housing (10). The assembly of the housing (10) and the coil is then sealed (10), in particular potted, with a sealant at the opposing axial ends in the regions between the hollow-fiber ends and the housing. The core assembly (1, 2) is made of at least two axially adjacent core parts (1, 1a, 1b, 2) arranged one behind the other, at least one (1, 1a, 1b) of which has a hollow design, and the core parts (1, 1a, 1b, 2) are kept in specified axial positions relative to each other, in particular at a distance to each other, by means of at least one aid element (7) at least over the period of the sealing process and preferably over the period of the winding process as well. After the sealing process and the removal of the at least one aid element (7), at least the axially end-face core parts (1, 1a, 2) are kept in their relative positions to each other by means of the sealant. The invention also relates to a coil, a core assembly, and a core system.
EXTRACORPOREAL OXYGENATOR WITH INTEGRATED AIR REMOVAL SYSTEM
Extracorporeal blood flow circuit devices can be used during medical procedures such as on-pump open-heart surgery. For example, extracorporeal heat exchange and oxygenation devices can be used to facilitate surgical procedures such as coronary artery bypass grafting. In some embodiments, such an oxygenation device can include an integrated air removal structure. In particular embodiments, the air removal structure can comprise one or more porous hollow fibers.
Device with inlet portion for treating a biological liquid
A device for treating a biological liquid has a housing with a first chamber defining a cavity and which is adapted to receive a liquid to be treated. At least one gas exchanger is at least partly disposed in the first chamber. An inlet portion is formed in a first surface of the housing for the inlet of the liquid to be treated into the chamber. The inlet portion is formed at an acute angle relative to the surface of the housing. Such a device allows a gas exchange in a lung assist method for example.
PRESSURE MEASURING DEVICE AND EXTRACORPOREAL CIRCULATOR
A pressure measuring device 30 installs on a tube 11 for transferring a medium (e.g., blood in a extracorporeal blood circulator) so as to measure a pressure of the medium inside the tube 11. The pressure measuring device 30 includes a main body portion 31 mountable to the tube 11, an image acquisition unit 32 disposed in the main body portion 31 so as to acquire image information on a pressure receiver that is deformed in response to the received pressure of the medium inside the tube 11, and a control unit 100 that converts the image information acquired by the image acquisition unit into pressure information about the pressure.
VA ECMO with pulmonary artery ventilation
A veno-arterial extracorporeal membrane oxygenation system includes a dual lumen drainage cannula configured for withdrawing blood from a patient's vasculature in a manner that provides a perfusion of oxygenated blood with reduced carbon dioxide content while unloading the left ventricle, with two points of access to the patient's vasculature. The dual lumen drainage cannula has a first drainage tube and a second drainage tube co-axially aligned with the first drainage tube. The first and second drainage tubes are fluidly coupled to a connector. A blood pump having a pump inlet is configured for fluidly connecting with the connector, while an oxygenator having an oxygenator inlet is configured for fluidly connecting with a pump outlet. An infusion cannula is configured for fluidly connecting with an oxygenator outlet for infusing oxygenated blood into a patient's bloodstream.
