20140042081 | Filter for Removing Substances from Blood or from Blood Derivatives, and a Method for Obtaining It - A filter for removing substances, including leukocytes and platelets by way of non-limiting example, from whole blood or from blood derivatives, the filter includes a casing containing a layered filter element, at least one layer of this latter being coated with polyurethane; this polyurethane has a number average molecular weight between 10,000 and 20,000 Dalton. A method for forming the layered filter element for a filter such as mentioned above, in which at least one layer of this filter element is impregnated with polyurethane by immersing it in a container of a mixture in which the polyurethane is present. This mixture includes a solution in which the polyurethane is dissolved in a polar solvent such as water. | 02-13-2014 |
20130168308 | FILTERING DEVICE FOR THE FUEL PUMP OF A VEHICLE - A filtering device for use in filtering fluids used in a vehicle such as its fuel, in which case the device is to be positioned on the suction side of a vehicle fuel pump, or in filtering a lubricant used in the vehicle, the device including a filter body presenting two opposing panels joined together to define a closed internal cavity, in one of the panels there being provided an aperture, the fluid filtered in passing through the body penetrating into the cavity, in this latter a spacer being positioned to maintain the panels separated and prevent their mutual contact. The spacer is of open-cell polymer foam material. | 07-04-2013 |
20130098912 | Overpressure Security Vent and Exhaust Device for a Container - A vent and exhaust device for a container within which an overpressure of gas can be created during use, such as a battery for a vehicle. The device having a hollow body, suited to being arranged on an opening of such container with internal cavity, closed but communicating with the outside and with a passage connected to the inside of the container from which the gas that forms in the latter can pass to escape to the outside of the aforesaid body. There being placed on such passage a filter element permeable to such gas. Such filter element is subject to pressure placed in such cavity and suited to pushing it in the position of interception of the passage, but allowing the momentary opening of the latter for a venting of the gas when the pressure exceeds a predetermined value. | 04-25-2013 |
20130066272 | MEDICAL INFUSION FILTER WITH OPTIMIZED FILLING - A medical infusion filter including a box body defined by at least two half shells coupled to define an internal cavity divided into at least two chambers by at least one hydrophilic filtering membrane. These chambers include at least one first or entry chamber and at least one second or exit chamber. The at least one first or entry chamber connected to an entry conduit for the medical fluid originating from a corresponding container. The at least one second or exit chamber connected to an exit conduit. At least the first or entry chamber is within a first half shell presenting at least one aperture within which a corresponding hydrophobic membrane is positioned. The at least one aperture enables a differential air flow rate to pass towards the exterior of the box casing as a function of distance of the casing air exit zone from the entry conduit. | 03-14-2013 |

20100185135 | PROTECTION FILTER FOR HEMODIALYSIS LINES - A protection filter for hemodialysis lines includes a body provided with conduit coupling members, a first conduit being connected to a dialysis machine and the second conduit being directed towards a patient. The coupling members present generally coaxial internal holes opening at their ends, the holes mutually communicating within the interior of the body, within the body a filter element is present disposed between the holes of the coupling members. The body of the filter is in one piece, is homogeneous and is without joining lines between its various parts. The body incorporates the end edges of the filter element. | 07-22-2010 |

20090192472 | SEALED DEVICE FOR REGULATING THE FLOW RATE OF MEDICAL LIQUID DIRECTED TOWARDS A PATIENT - A device for regulating the flow rate of a medical liquid includes a body provided with elements associated with corresponding parts connected together but torsionally free, at least one of the parts including a plurality of recesses acting as flow regulator able to modify the flow rate of the liquid directed towards the patient by rotating the parts about a common axis of rotation. Between the parts a seal element enables the recesses to be selectively connected together via communication elements, so achieving flow rate regulation. Transverse sealers are provided between the seal element and at least the second part of the parts which are interconnected but torsionally free. The transverse sealers preventing the escape of liquid from the recesses and from the body of the device following a relative movement or misalignment between the parts in a plane perpendicular to the axis of rotation or along this latter during flow regulation or following any angular misalignment of the parts relative to the axis. | 07-30-2009 |
