Abstract: A filter for medical infusion lines includes a box-like body having an inlet connector and inside which there is arranged a plate-like element on whose one or both opposite faces there are formed respective channels placed in communication with an outlet connector. Filtering hydrophilic membranes separate the channels from at least one interspace placed in communication with the inlet connector. With the outlet connector there is operatively associated an overpressure valve incorporated in the box-like body of the filter.

Abstract: Filter for infusion medical lines having a box-like body within which there are arranged four filtering hydrophilic membranes parallel and spaced from each other so as to form three interspaces placed in communication with the inlet connector of the liquid to be filtered.

Abstract: Roller clamp for regulating the flow of a fluid through an elastically deformable tubing including a generally channel-shaped body whose bottom wall has a clamping surface with a longitudinal groove with a cross-section decreasingly variable from an initial end towards a terminal end. The longitudinal groove is arranged asymmetrically with respect to the lateral walls of the body.

Abstract: A pressure pod for haemodialysis medical lines includes a hollow body with an intermediate flexible membrane which delimits a gas chamber and a liquid chamber with inlet and outlet tubular fittings for connection to the haemodialysis medical line. A female luer-lock connector has an outer tubular body and an inner tubular body on which the outer tubular body is axially blocked rotatably. A tubular fitting is engaged within an annular cavity formed between the inner and outer tubular bodies of the female connector.

Abstract: A Y-connector for medical lines, includes a tubular body provided with a first inlet coaxial to the tubular body and containing a valve device formed by an elastic element, and a second inlet arranged obliquely to the tubular body and communicating therewith between the first inlet and the outlet. The tubular body is formed with an inner septum for deviating a flow coming from the second inlet towards the hollow elastic element prior to directing the flow to the outlet.

Abstract: A filter for infusion medical lines including a flattened box-like body provided inside which is a plate-shaped element formed on whose one or both of the opposite faces are respective ribs defining inner channels. Arranged on the ribs are respective filtering hydrophilic membranes which separate the channels from respective interspaces delimited by a pair of half-shells. The interspaces are placed in communication with the inlet connector, the channels are placed in communication with the outlet fitting and the interspaces are placed in communication with the outside through vent openings arranged on the end walls of the box-like body.

Abstract: A valve connector for infusion medical lines includes an outer tubular body, an inner hollow spike and an intermediate sealing member formed by an elastic hollow element including a head with a pre-slit normally closed. The elastic hollow element has a base part substantially generally barrel-shaped and a wall having a differentiated radial thickness.

Abstract: A foot valve for drip chambers of medical infusion or transfusion apparatuses having an annular valve seat with which a float obturator axially displaceable between a position for closing and a position for opening the valve seat cooperates. A containment cage bush has an elastically deformable lateral wall within which the float obturator floats in a guided fashion, and the lateral wall of the containment bush and the float have respective mutually facing surfaces configured such that a radial deformation of the containment bush applies an axial thrust to the float obturator in the direction of moving it apart from the annular valve seat.

Abstract: A flow component particularly for hemodialysis medical lines includes a duct having a first and a second end tubular connector coaxial to each other and designed to be connected to the line, and an intermediate tubular connector of the female luer type arranged orthogonally to the duct. A hollow elastic element substantially extends along the entire intermediate tubular connector and the body is internally configured so that, in use, the flow along the duct is partly diverted towards the intermediate tubular connector and introduced with a swirling motion along the cavity of the hollow elastic element.

Abstract: A tubular fitting for medical fluid lines includes a hollow body within which a male connector and an opposite female connector are coaxially housed. The male connector is coupled in rotation with respect to the body in a direction corresponding to a screwing with a female connector of the line, while it is normally freely rotatable in the unscrewing direction, in the same way as the female connector is coupled in rotation with respect to the body in the direction corresponding to the screwing with a male connector of the line, while it is normally freely rotatable in the unscrewing direction. The male connector and/or the female connector can possibly be locked in rotation with respect to the body in the unscrewing direction, only following a positive command.

Abstract: Drip chamber and spike assembly for medical lines, including a generally cylindrical body whose end edge is fixed on a hollow tang of the spike assembly and it is externally formed with a crown of integral reliefs defining a grasping element.

Abstract: A Y-connector for medical lines, includes a tubular body provided with a first inlet coaxial to the tubular body and containing a valve device formed by an elastic element, and a second inlet arranged obliquely to the tubular body and communicating therewith between the first inlet and the outlet. The tubular body is formed with an inner septum for deviating a flow coming from the second inlet towards the hollow elastic element prior to directing the flow to the outlet.

Abstract: A method for checking a faultless joint between a first and a second component of a medical device, namely a drip chamber and a spike, wherein the first component has an annular coupling edge facing downwardly to be sprayed interiorly with a liquid solvent. The solvent is mixed with a tracer detectable through ultraviolet or infrared light and the coupling edge is illuminated with a ultraviolet or infrared light so as to make an image of the sprayed solvent, which is reflected and captured by an electronic scanning device configured to establish whether such image is faultless, visible through a tracer.

Abstract: A valve connector for hemodialysis lines includes a male luer lock valved fitting, a female luer lock fitting that can be engaged with the male luer lock fitting, and a rotatable ring nut carried by the male luer lock fitting and that can be screwed with the female luer lock fitting. Before the rotatable ring nut begins the screwing on the female luer lock fitting, the male luer lock valved fitting is fully opened, and as soon as the ring nut ceases the unscrewing from the female luer lock fitting, the male luer lock valved fitting fully closes instantly.

Abstract: A cap for medical fluid lines and the like includes a hollow body within which a male or female connector accessible at one end of the body is coaxially housed. The connector is configured to inviolably obstruct the passage through the body. A unidirectional coupling locks in rotation the connector with respect to the body in the direction corresponding to the screwing of the connector, and a complementary connector, and to enable free rotation of the connector in the opposite direction. The connector can be possibly locked in rotation with respect to the body in the unscrewing direction, only following a positive command.
