Abstract: A valved male luer connector includes a resilient hollow element enclosing a tubular member having an inlet portion and an outlet portion. A collar is axially displaceable to cause a stretching deformation of the resilient hollow element so as to open a cut of a terminal wall thereof adjacent to an initial end of the inlet portion of the tubular member. The collar has a containment axial appendage of the resilient hollow element up to close to the terminal wall thereof. A stop means for limiting the stretching deformation of the resilient hollow element is provided for in the zone close to the terminal wall thereof.

Abstract: A device for the controlled supply of a liquid within a medical flow line, includes a retaining body rotatable on an intermediate tubular connector arranged between a tubular inlet connector and a tubular outlet connector of a primary liquid and within which a bottle pierceable and containing a secondary liquid can be fitted. The retaining body includes a hollow piercing spike, rotation blocking means of the retaining body disengageable following insertion of the bottle, axial stop means of the inserted bottle, and progressive opening means of a flow passage from the hollow spike to a flow line of the primary liquid during the rotation of the retaining body with the bottle inserted therein from a first angular position of complete closure to a second angular position of complete opening.

Abstract: A medical device, particularly for mixing medical fluids, includes two tubular bodies made of materials of different elasticity having respective open ends to be joined together. The end of the second body is inserted axially by friction within the end of the first body and is then blocked via radial projections, which are obtained by plastic deformation of the wall of the end of the first body and are engaged against the end of the second body.

Abstract: A check valve for medical infusion lines and the like, includes a diaphragm made of elastic material set between a first tubular connector and a second tubular connector. The diaphragm includes an end wall of a cup-shaped element, having an outer peripheral edge of which is normally pressed in seal contact against an annular valve seat with a conical surface of the first tubular connector under an axial thrust exerted by a side wall of the cup-shaped element. A free edge of the side wall of the cup-shaped element is set resting against a transverse surface of the second tubular connector only in regions corresponding to angular portions of the latter separated by non-resting angular portions.

Abstract: Valve connector for infusion medical lines including an external tubular body (1) with an inlet end (4) and an outlet end (10), an internal hollow spike (2) and an intermediate sealing member (3) including an elastic head (35) with pre-slit (38) and an elastic hollow element (36) formed with sealing members (47, 48) in contact with the hollow spike (2) and with an elastic thrust means tending to maintain the elastic head (35) in a closure condition. An annular member (55) surrounds the elastic hollow element (36) and it axially slides into the tubular body (1) due to the movement of the elastic head (35) between the closure condition and the opening condition of the connector.

Abstract: A valve connector for medical infusion lines including an external tubular body with an inlet end and an outlet end, an internal hollow spike and an intermediate sealing member including a head with pre-slit and an elastic hollow element formed with fluid-tight members in contact with the hollow spike and with an elastic thrust means, which tends to maintain the elastic head in a closed condition. The elastic thrust means comprises a base part joined to the elastic hollow element of the sealing member through a generally transverse annular wall, which, during axial displacement of the elastic head from the closed condition to the open condition, bends within an annular chamber defined between the base part and a portion with conical surface of the hollow spike.

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

Abstract: Syringe (1) including a cylinder (2) and a piston (4), in which the outlet end (6) of the cylinder (2) is integrated with a valve male luer lock connector (7).

Abstract: A valve connector for medical infusion lines includes an external tubular body with an inlet end and an outlet end, a hollow internal pin and an intermediate elastic sealing member 3 having a head with pre-slotting and an elastic hollow element abutted radially against the hollow pin. The hollow pin has a closed terminal shaped, as a result of the insertion of a fluid introducer into the inlet end, in such a way as to make the elastic head assume an elastically deformed configuration without crossing the pre-slotting, which is opened to place in communication the inlet end with the outlet end through lateral holes of the hollow pin.

Abstract: A medical valve connector comprising a tubular body having an inlet fitting of the male luer or luer-lock type with an inner tubular element displaceable axially from a retracted position for closing a passage of flow towards an outlet fitting to an advanced position for opening said passage of flow. A tubular body made of elastic material, set between the inlet and outlet fittings, tends to keep the inner tubular element in the retracted position. Also the outlet fitting can rotate and axially translate between a retracted position and an advanced position.
