An adapter slip configured to be seated in a fluid port, the adapter slip including a lumen, an exterior wall, a shoulder, and a sleeve. The lumen extending along a length of a longitudinal axis, the lumen configured to receive a temperature probe. The exterior wall including a proximal end portion and a distal end portion, wherein the proximal end portion includes a tapered portion tapered at an acute angle with respect to the longitudinal axis. The shoulder extending outward from the exterior wall distal to the tapered portion configured to engage with a distal end of the fluid port. The sleeve configured extend within the lumen and project a predetermined distance beyond the proximal end portion of the exterior wall, the sleeve including a sleeve lumen and a closed proximal end, the sleeve lumen configured to receive at least a temperature sensor of the temperature probe.

A method of manufacturing a bundled mat construction for an extracorporeal blood circuit heat exchanger includes attaching a leading edge of a first capillary tube mat segment to a first side of a mandrel. A leading edge of a second capillary tube mat segment is attached to a second side of the mandrel. The first side is diametrically opposite the second side. The mandrel is rolled relative to the mat segments to generate a bundled mat construction. Radial layers of the bundled mat construction are symmetrical relative to a central axis of the mandrel.

Rolled mat heat exchanger and method of manufacture

A cardiotomy and venous blood reservoir, including a housing assembly, a venous inlet port, a venous sub-assembly, a cardiotomy inlet port, and a cardiotomy sub-assembly. The housing forms a chamber. The venous sub-assembly includes a downtube and a bowl. A diameter of the downtube lumen increases to a downstream end. The bowl forms a floor surface for receiving flow from the lumen. The cardiotomy sub-assembly includes a dish and an inner post. The dish defines an aperture. The inner post extends from the dish and forms a guide surface received within the central aperture and forming an undulating curvature increasing to a diameter greater than the diameter of the central aperture. Cardiotomy liquid drops from the dish fall on to the undulating, closely positioned guide surface with minimal splashing.

Cardiotomy and venous blood reservoir and method

A cardiotomy and venous blood reservoir including a housing assembly, a downtube, and a bowl. The housing assembly forms a chamber. The downtube extends from an inlet port to a downstream end within the chamber. A diameter of the tube lumen increases to the downstream end. The bowl forms a floor surface shoulder, intermediate segment, and protrusion. The shoulder circumferentially surrounds, and is spatially above, the downstream end. The intermediate segment extends radially inwardly and downwardly from the shoulder to a bottom face. The protrusion extends radially inwardly and upwardly from the bottom face to a center that is aligned with the lumen and below the downstream end. The flared inner diameter of the lumen reduces fluid velocity as venous blood enters the reservoir. The bowl floor surface gently receives the incoming venous blood at the protrusion, and smoothly guides the blood flow.

Device for adapting a temperature probe for a use in a port in a heart-lung machine. An adaptor slip is tapered at an adaptor taper angle less than a port taper angle. The adaptor slip is sized such that the exterior wall of the adaptor slip provides an interference fit with at least a portion of the fluid port. The adaptor slip has an external shoulder abutting the end of the fluid port. The adaptor slip additionally has a sleeve having a closed end having a position with respect to the end of the adapter slip. A probe is configured to be seated in a lumen of the adaptor slip with a proximate end of the probe being proximate to the closed end of said sleeve.
