초록 ▼

A novel integral cardiotomy/venous blood reservoir, blood oxygenator and heat exchanging device, method of making a blood oxygenating and heat exchanging device and an extracorporeal circulatory support circuit. The reservoir includes a novel blood defoaming and filtering chamber closely receiving filtering and defoaming media. The blood oxygenating and heat exchanging device includes thermal formed housing portions, and a heat exchanging barrier, blood oxygenating medium and/or filtering medium, which are sealed by potting compound at one time. The oxygenating medium comprises a hollow fiber type medium, with its ends left open to be sealingly mounted in a gas path by a novel mounting bracket.

대표청구항 ▼

An integral blood oxygenating and heat exchanging apparatus for oxygenating blood and heating or cooling blood, the apparatus being adapted to be operatively connected with a mounting device that brings a source of oxygen rich gas and heat-exchanging fluid into fluid communication with the apparatus, the apparatus comprising: a separation medium comprising hollow fibers for separating blood and gas while permitting transfer of oxygen and carbon dioxide across the medium to oxygenate the blood, the separation medium being arranged in an array having opposite ends, the hollow fibers having internal lumens with open ends open at the opposite ends of the separation medium such that gas may flow through the lumens of the hollow fibers; a heat exchanging barrier for separating blood and a heat-exchanging fluid while permitting heat transfer across the barrier to heat or cool the blood, the barrier having opposite ends positioned generally adjacent and generally aligned with the opposite ends of the separation medium, the heat exchanging barrier having at least one internal lumen with open ends open at the opposite ends of the heat exchanging barrier; a housing holding the separation medium and the heat exchanging barrier, the housing being formed into a configuration corresponding to the separation medium and the heat exchanging barrier without enclosing the open ends of the lumens of the hollow fibers of the separation medium and the open ends of the lumen of the heat exchanging barrier; and potting compound sealing the housing adjacent the ends of the separation medium and heat exchanging barrier without closing the open ends of the lumens of the hollow fibers of the separation medium and the open ends of the lumen of the heat exchanging barrier; a blood inlet and outlet into the housing defining a blood flow path inside the housing across the separation medium outside of the hollow fibers and along the outside of the heat exchanging barrier; and the open ends of the lumens of the hollow fibers and the open ends of the lumen of the heat exchanging barrier opening directly into the environment outside the housing to allow them to be brought into direct fluid communication with the device.
