20140046248 | HEAT EXCHANGE DEVICE - The present invention relates to a device designed to promote heat exchange to/from a medical liquid ML. The device comprises an inlet, an outlet and a duct adapted to contain a flow of the medical liquid ML. The duct is enclosed between two walls, has a planar development defining a mean plane π, and comprises means for promoting turbulence in the flow of the liquid ML. At least one wall of the duct is suitable to allow a heat exchange with the flow of the liquid ML. The means for promoting turbulence comprises a plurality of fins, wherein each fin has a lenticular cross section and defines its own mean plane τ | 02-13-2014 |
20140037480 | TUBULAR INSERT FOR EXTRA-CORPOREAL CIRCUIT - The present invention relates to a novel type of tubular insert for connecting an extra-corporeal circuit to a peristaltic pump. This tubular insert comprises a loop formed by a tube portion; the loop comprises a curve which extends around an axis X. The tube which forms the curve has an oval cross-section with a major axis M and a minor axis m perpendicular to each other, where the major axis M is longer than the minor axis m. Finally, in the tubular insert according to the invention, the minor axis m of each cross-section of the tube along the curve is parallel to the axis X The invention further relates to a method for producing the tubular insert and to a peristaltic pump suitable for operating with tubular inserts according both to the invention and to the prior art. | 02-06-2014 |
