Abstract: A three-way connector (1) including a body (2) with a tubular central part (3) having a first (4) and a second (5) opposite ends, the first end being open and the second end being closed, an internal cavity (6) of the tubular central part (3) communicating with internal ducts (7, 8, 9) of connection portions (10, 11, 12) which project radially from said tubular central part (3), a first (10) and a second (11) intake connection portion being able to receive fluids, at least one of these fluids being infused to a patient by means of the third, output connection portion (12), a tubular valve element (13) with an internal cavity (16) being inserted inside the internal cavity (6) of said central portion (3), and projecting from the first, open end (4) of said tubular central part (3) with a grasping portion (17) thereof with radial arms (17A).

Abstract: 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.

Abstract: A device for regulating the flow rate of a liquid in a medical infusion line, includes a body presenting elements for its connection to a first and to a second conduit connected to a container for the liquid and directed to a patient respectively, the body presenting a plurality of parts connected together but torsionally free about a common axis of rotation (K) to enable flow rate variation elements, associated with the body, to modify the flow rate variation elements are a plurality of recesses provided in a single part of the body, a first recess being annular and of constant depth, and at least one second recess being in the form of a broken ring and of variable depth, the recesses being concentric.

Abstract: A filter comprises a box casing in which at least one cavity is present between an outer element of the casing and an inner surface presenting a plurality of channels on which a corresponding hydrophilic filtering membrane lies, the cavity communicating with a conduit for entry of the fluid into the filter and the channels being connected to a conduit for exit of the fluid, in the outer element there being provided through apertures with which hydrophobic membranes are associated. A surface bounded by the shortest possible ideal closed line, which totally comprises all the hydrophobic membranes, contains substantially within its interior the projection thereon of the useful hydrophilic surface of the hydrophilic filtering membrane, this enabling the filter to be employed in a plurality of spatial positions during its use.

Abstract: A device for regulating the flow rate of a liquid in a medical infusion line, said device (1) comprising a body (2) presenting elements (40, 59) for its connection to a first and to a second conduit connected to a container of said liquid and directed to a patient respectively, the body (2) presenting a plurality of parts (3, 4) connected together but torsionally free about a common axis of rotation (K) to enable flow rate variation means (54, 55, 67), associated with the body (2), to modify the flow rate of the liquid fed to the patient. The flow rate variation means are a plurality of recesses (54, 55, 67) provided in a single part (4) of said body (2), a first recess (54) being annular and of constant depth, and at least one second recess (55, 67) being in the form of a broken ring and of variable depth, said recesses (54, 55, 67) being concentric.
