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: Cannula with protection cap for medical infusion lines and the like, comprising a hollow body provided at one end with a female luer lock connector and at the other end with an axial tubular ferrule. The hollow body and the protection cap are provided with respective formations for mutual torsional coupling acting in the direction of rotation corresponding to the unscrewing of the female luer lock connector relative to a male luer lock connector of the medical line.

Abstract: Medical connector comprising a tubular body with an inlet fitting and an outlet fitting of the female luer-lock type connected to the body in a rotary and axially translatable way between a retracted position and an advanced position. One-directional detent assemblies enable rotation of the outlet fitting in one direction in the retracted position and in the opposite direction in the advanced position.

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.

Abstract: Described herein is a drip chamber for medical lines with a generally cylindrical body having an inlet, on which a precision flow regulator is directly applied.

Abstract: Transducer-protector device for biomedical haemodialysis lines comprising a first and a second element each of which is formed in a single piece of moulded plastic material with a tubular fitting and an annular radial flange. The first element is formed with a semi-crystalline polymer and the related annular radial flange has greatly thinner portions able to allow the see-through viewing of the filtering membrane secured between the flanges of the first and of the second element.

Abstract: A flow regulator for medical liquids comprising a first body and a second body coupled to one another in a rotatable way and a gasket set between them and overmoulded on the second body. Provided thereon is at least one graduated scale formed by impressions and/or, respectively, by reliefs integral with the second body, and by inserts and/or, respectively, by complementary openings of a side skirt of the overmoulded gasket.

Abstract: A flow component for medical infusion/transfusion lines comprises a main duct and a lateral tubular connection containing a one-way valve, in an area corresponding to which the main duct has an axial section with a wall having a convergent-divergent profile.

Abstract: A male luer lock connector for medical fluid lines comprising an elongated tubular body having an end portion with external luer cone and an internally threaded bushing mounted so that it can turn and slide on a portion with a cylindrical external surface of the tubular body. Cooperating formations disposed between the portion with cylindrical external surface of the tubular body and the bushing are provided to produce during use a perceptible click when the bushing draws near to a fully advanced position of engagement with a female luer lock connector.

Abstract: Flat filter for venting gas in intravenous medical lines, comprising a case formed by a frontal plate and by a dorsal plate between which a hydrophilic filtering membrane is interposed. The dorsal plate has a single through hole for gas venting in communication with an elongated collecting channel formed on the inner surface of the dorsal plate and along which a hydrophobic membrane of complementary shape is applied.

Abstract: A male luer lock connector for medical fluid lines comprising an elongated tubular body having an end portion with external luer cone and an internally threaded bushing mounted so that it can turn and slide on a portion with a cylindrical external surface of the tubular body. Cooperating formations disposed between the portion with cylindrical external surface of the tubular body and the bushing are provided to produce during use a perceptible click when the bushing draws near to a fully advanced position of engagement with a female luer lock connector.

Abstract: A check valve for medical infusion lines and the like, including a diaphragm made of elastically deformable material inserted between an upstream passageway and a downstream passageway and cooperating with an annular valve seat to keep the check valve normally closed. The annular valve seat is formed by a front surface of the first tubular element, and the diaphragm consists of the bottom wall of a cup-shaped element arranged coaxially with the upstream and downstream passageways.

Abstract: Transducer-protector device for biomedical haemodialysis lines, comprising a first tubular connector of the female Luer Lock type and a second tubular connector which are coaxial to each other and provided with a first and a second annular radial flange, respectively, for their mutual permanent sealed connection by ultrasonic welding, and a filtering membrane interposed and clamped between the first and second annular flanges. The second tubular connector with the second annular flange is formed in one piece of high rigidity molded thermoplastic material, while the first tubular connector with the first annular flange is formed in one piece of a molded thermoplastic material having higher elasticity characteristics, conveniently selected in the class of polybutylenterephthalate polymers.
