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.

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: 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 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 valved male luer connector includes an elastic hollow element which encloses a tubular member having an inlet portion and an outlet portion. A collar is axially displaceable causing a stretching deformation of the elastic hollow element and opening the flow passage between the inlet portion and the outlet portion of the tubular member. A priming cap is designed to be releasably connected to the casing of the valved connector to provide stretching deformation of the elastic element and keep the outlet portion of the tubular member in communication with the atmosphere through a liquid-impermeable barrier.

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 vial access device, includes a body having a projecting annular skirt that is elastically deformable, for engaging a complementary shaped neck of a vial. A tubular spike extends coaxially within the annular skirt for introducing into the vial, and a tubular connector protrudes from the body on the side opposite to the annular skirt and in fluid communication with the tubular spike. The tubular spike and the annular skirt are arranged, respectively, within a first and a second part, distinct from each other, and of which the first part is permanently joined to the body and the second part is connectable to the first part through an irreversible coupling.

Abstract: An access device for containers of fluidizable substances includes a body provided with a hollow spike designed to be inserted into a container of a substance to fluidize and having an axial fluid passage and an axial passage for venting of the container, an expandable chamber connected to the venting passage of the spike through a lateral passage of the body, a first check valve enabling one-way communication from the lateral passage to the expandable chamber, a second check valve enabling one-way communication from a vent opening to the venting passage of the spike. A double impermeable filtering membrane is interposed between the first check valve and the second check valve.

Abstract: A flow component particularly for haemodialysis 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 connector for medical lines includes a tubular body having a male luer-lock fitting at one end, intended to be screw-coupled with a complementary female fitting. An outer jacket is coupled in unidirectional rotation with the tubular body in the direction corresponding to the screwing of the male fitting and freely rotatable in the opposite direction. For selectively coupling the outer jacket with the tubular body in the direction corresponding to the unscrewing of the male fitting, at least one side push-button carried by said outer jacket is provided.

Abstract: An injection site for medical lines includes a tubular body made of molded plastic material within which an elastic element made of thermoplastic material is overmolded on an enlarged end of the tubular body. The enlarged end delimits an inner annular flange and is formed with at least one radial through-hole through which the elastic element is overmolded in order to rest axially against the inner annular flange and fill the radial through-hole with an appendage.

Abstract: A valve connector for medical lines includes a tubular body having a male inlet fitting with an external luer cone, which can be coupled to a female tubular fitting with an internal luer cone, wherein the male inlet fitting includes an internally threaded external tubular element for screwed engagement with the female fitting, and an internal tubular element that can be displaced axially from a retracted position of closing to an advanced position of opening of a valve that controls a passage of flow through the connector. The internally threaded external tubular element is free to turn, and an arrangement is such that, when the internally threaded external tubular element is screwed off the female fitting and the passage of flow is closed by the valve, the external luer cone and the internal luer cone remain axially coupled to one another by friction.

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.
