摘要:
An injection site for tubular medical connectors, includes a perforable body inserted in a seat of a connector delimited by an annular wall having a retention edge turned in against the outer end of the perforable body. The outer end is formed with a peripheral annular step and with an exposed portion with reduced cross section projecting axially. The peripheral step is defined by an annular groove having a shape complementary to that of the turned-in retention edge of the connector, and the portion with reduced cross section of the perforable body connects up to the groove through an annular surface projecting radially above at least part of the turned-in retention edge and resting against it.
摘要:
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.
摘要:
A valve connector for medical infusion lines including a tubular body (1) with an inlet (4) and an outlet (10), an internal hollow spike (2), and a sealing member (3) including an elastic head (14) with pre-slit (17) normally kept in an undeformed closed condition within the inlet (4). The outlet (10) comprises a pierceable injection point (22) coaxially facing the hollow spike (2).
摘要:
A flow component for medical infusion/transfusion lines includes a tubular body having a side inlet connector, housed in a fluid-tight way in which is an elastic sealing element that can be traversed by a fluid introducer. The elastic sealing element has at least one axial cavity, which defines, for traversal by the fluid introducer, a diaphragm of small thickness.
摘要:
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.
摘要:
A device for administering medical liquids comprising a tubular element made of moulded plastic material and an elastic sealing body made of elastic thermoplastic material overmoulded within one end of the tubular element with a part for anchorage on the outside of said end.
摘要:
A check valve and, in particular, an anti-siphon valve, for medical infusion lines and the like, including an axial upstream passageway and an axial downstream passageway, staggered and parallel with respect to each other, and a diaphragm of elastic material cooperating with an annular valve seat for normally keeping communication between these passageways closed. The diaphragm is composed of the end wall of a cup-shaped element on which a plunger rests coaxially, the plunger being slidable between a retracted inoperative position and an advanced operative position. Valve opening occurs following flexion of the diaphragm, which can be spontaneous due to a predetermined fluid pressure developing in the upstream passageway, or positively operated via the plunger (9).
摘要:
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.
摘要:
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.
