    Field of Invention
    [001] The present invention relates, in general, to connectors for medical fluids and, more in particular, with reference to a male luer connector with valve, designed to be connected to a female luer connector to open a flow passage through the two connectors. Previous Technique
    [002] Considering its use in the medical field, connectors made in this way must be able to guarantee a perfect closure in the absence of the female connector, an instantaneous coupling during coupling with the female connector and an instantaneous return to the closed position after the female connector uncoupling.
    [003] In order to obtain such effects, a valved male luer connector comprising a housing, a tubular member having an inlet part with an initial end and an outlet part and a hollow resilient member secured to the housing and sealing axially and slidingly the inlet of the tubular member was proposed in US patent 7,559,530 transferred to the Applicant. The hollow resilient element has an end wall having a cut and adjacent to the leading end of the inlet portion of the tubular member, and a collar is interposed between the housing and the hollow resilient element. The collar is axially displaceable, second to the engagement tightened by a female connector, to cause a deformation in the stretching of the hollow resilient element, with the consequent opening of the cut mentioned above and the flow passage between the inlet part and the outlet of the tubular member.
    [004] Thus, this male luer connector with valve operates differently from the valve connector analogous to the prior art, due to stretch deformation rather than a compression of the hollow resilient element that defines, through the end wall thereof with the cut , the closing valve member.
    [005] Although fully efficient in the case where the connector is intended for disposable use or for a limited number of uses, this prior art connector has disadvantages in the case of repeated opening and rewiring cycles. risk of an inadequate sealed reconnection by the end wall of the hollow resilient element, caused by protrusions or even breaks in the cutting zone, in turn, due to an asymmetrical deviation or deformations of the hollow resilient element during the stretching of its extension, which it would also have an impact on the subsequent correct elastic return to the undeformed condition.
    [006] An additional disadvantage of this prior art valved male luer connector is the fact that possibly the resilient hollow element, which is freely exposed on the outside in the closed condition, may be inadvertently or even intentionally deformed creating an unopened opening. desired and risky cut of the relative end wall. Invention Summary
    [007] The present invention aims to improve the aforementioned connector known from the aforementioned document US-7,559,530 and, more in particular, to reduce the risk of malfunction due to incorrect deformations of the hollow resilient element, and the problems with respect to secure and reliable closure of the end wall cut-out thereof.
    [008] A further aim of the invention is to prevent the inadvertent or, however, undesired opening of the cutting of the end wall of the hollow resilient element.
    [009] According to the invention, these objectives are achieved due to a male luer valve connector of the type defined in the preamble of claim 1, whose main feature is the fact that the collar interposed between the compartment and the hollow resilient element has an axial containment attachment for said hollow member resilient to substantial proximity to the end wall thereof.
    [010] This idea of solution allows obtaining several important advantages.
    [011] First, the containment action exerted by the axial attachment of the collar prevents uncontrolled or, however, incorrect deformations of the side wall of the hollow resilient element during its stretch deformation, thus ensuring the perfect closing of the wall cut relative terminal even following the repeated opening and rewiring cycles of the valve connector.
    [012] On the other hand, the presence of the axial attachment of the collar drastically reduces the risk of lacerations of the end wall of the hollow resilient element in the relative cut and, in the case of a laceration, its propagation is, however, limited or interrupted.
    [013] The stretch deformation of the resilient hollow element is thus well controlled for almost the entire axial extension thereof comprised between the end wall thereof and the collar zone from which the relative axial containment attachment extends.
    [014] According to a preferred embodiment of the invention, the side wall of the hollow resilient element has an external radial flange that faces axially toward the aforementioned axial containment attachment of the collar.
    [015] The boundary between such external radial flange and the free end of the axial containment attachment of the collar allows, in the closed condition of the connector, to further prevent the undesired or inadvertent opening of the cut of the end wall of the hollow resilient element. Additionally, such radial flange advantageously allows to provide the positive reconnection of such a cut, allowing the opening of the same by the female connector and the subsequent removal of the latter. Such positive rewiring effect, determined by the axial tightening applied by the axial containment attachment of the collar against the outer radial flange of the end wall of the resilient hollow element, further contributes to ensuring perfect closure of the connector even after repeated opening and rewiring cycles , in addition to efficiently controlling the resilient deformation of the hollow element and the end wall relative to the cut.
    [016] Such an effect is further enhanced due to the fact that, according to an additional advantageous feature of the invention, the tubular member has, near the initial end of the inlet part thereof, an outer annular groove within which a projection guides The inner part of the hollow resilient element is slidably fitted.
    [017] The cooperation between such internal guide projection of the hollow resilient element and the external groove of the tubular member substantially limits the locking means of the stretch deformation of the zone of the hollow resilient element close to the end wall thereof, further contributing to avoid the risk of lacerations or breakages in the area of such cut.
    [018] In order to ensure a gradual opening, as free as possible from shearing of the end wall of the resilient hollow element during coupling between the male luer connector with valve and a female connector, the initial end mentioned above of the part of tubular member inlet is conveniently formed with an outer annular rounded enlargement. Brief Description of Drawings
    [019] The additional features and advantages of the invention should be clear from the detailed description below, with reference to the attached drawings purely by way of non-limiting example, in which:
    [020] Figure 1 is a schematic perspective view of a male luer valve connector according to the invention;
    [021] figure 2 is an axial sectional view of figure 1;
    [022] Figure 3 is an exploded perspective view of the connector;
    [023] Figure 4 is a sectional view of Figure 3; and
    [024] figures 5, 6 and 7 are schematic sectional views analogous to figure 2 that exemplify the different stages of operation of the male luer connector with valve according to the invention. Detailed Description of the Invention
    [025] Initially, with reference to figures 1 to 4, the male luer valve connector according to the invention comprises a housing 1 consisting of a lower flange portion 2 permanently coupled to an upper hollow body 3 formed on the opposite side to flange 2, with an internally threaded seat 4.
    [026] The flange 2 is, in turn, integrally and coaxially formed with a tubular member indicated in its entirety with 5, which has an inlet part 6 extending through the hollow body 3 that projects out of the respective seat threaded 4, and an outlet part 7. The inlet part 6, along with other parts to be described later in this document, defines with the threaded seat 4 a male luer lock connector designed to be engaged by a female connector, not illustrated insofar as it is known per se. For example, the female connector may be of the valve type described and illustrated in patent application EP-1834665A2 also in the name of the Applicant.
    [027] The outlet part 7 communicates with a tubular attachment 8, for example, configured as a female lock luer connector, also formed integrally with the flange 2 and which protrudes at the rear with respect to the compartment 1.
    [028] The input 6 and output 7 parts are connected to each other through two series of separate radial passages 9, 10 whose mutual communication is controlled as explained later in this document.
    [029] The inlet part 6 has an initial open end, indicated by 11, in which an annular enlargement of rounded wall 12 is formed that delimits, at the top, an outer annular groove 13, in turn, delimited on the inner part by a blocking step 14.
    [030] A hollow resilient element, typically an elastomer or silicone rubber, which includes an annular base 16 secured in the housing 1 between the flange 2 and the body 3, a generally cylindrical first part 17 connected to the base 16 through a generally conical part 18 which diverges towards such cylindrical part 17, and a second generally cylindrical part 19 slightly narrow with respect to the first cylindrical part 17 and which has a transverse end wall 20 is indicated by 15 .
    [031] The end wall 20 is provided, centrally, with a cut 21, for example, in linear or tricuspid type format in the case of the illustrated example, normally closed due to the resilience characteristic of the hollow resilient element 15. A radial flange outer 22, whose function is to be explained later in this document, projects from the edge of the perimeter of end wall 20.
    [032] The second cylindrical part 19 of the hollow resilient element 15 is internally formed with an annular guide projection 23, sliding within the groove 13 of the inlet part 6 of the tubular member 5, between the annular enlargement 12 and step 14.
    [033] The first cylindrical part 17 is internally formed having at least a first, a second and a third annular sealing projection spaced apart from each other, respectively indicated by 24, 25 and 26, in sliding sealing contact on the tubular member 5 .
    [034] The end wall 20 of the hollow resilient element 15 is generally disposed immediately above the starting end 11 of the inlet part 6, with the cut 21 thereof held closed. Such position corresponds to the closed position of the valve connector, shown in figures 1, 2 and 5, in which the communication between the radial passages 9 and 10 of the tubular member 5 are isolated from each other at least by the internal annular projection 24 of the hollow element resiliently 15, therefore, communication between the inlet part 6 and the outlet part 7, i.e. the flow passage through the connector, is impeded.
    [035] A collar interposed between the hollow body 3 of the compartment 1 and the hollow resilient element 15 and which constitutes, as can be seen from this point onwards, an actuator member designed to control the opening of the flow passage through the connector that follows the coupling thereof with the female luer connector, due to a stretch deformation of the hollow resilient element 15 is indicated by reference numeral 28.
    [036] The collar 28 seals the first cylindrical part 17 of the hollow resilient element 15 and the bottom 29 thereof is engaged with the conical part 18 of such hollow resilient element 15.
    [037] According to the distinctive feature of the invention, the collar 28 is also provided with, at the top, an axial containment attachment 30 that seals the second cylindrical part 19 of the hollow resilient element 15 and extends substantially close to the wall terminal 20 of it. The free end of the containment attachment 30 faces axially towards the outer radial flange 22 of the end wall 20.
    [038] The axial containment attachment 30 of the collar 28 has an external engagement surface of the female connector, for example, though not necessarily, a luer cone.
    [039] The valve connector according to the invention operates as follows.
    [040] In the closed condition, as shown in figures 1, 2 and 5, the cut 21 of the end wall 20 of the hollow resilient element 15 is closed and the inadvertent or, however, unwanted opening thereof is prevented by the presence of the attachment of axial containment 30, against which the outer radial flange 22 abuts in the event of an attempt to push or deform the cylindrical part 19 downwardly with the end wall 20 which tends to cause the opening of the cut 21.
    [041] In order to provide the opening of the connector, it is necessary to introduce and couple a female luer connector to seat 4 of structure 3: due to such introduction, the female connector as mentioned is not shown in the drawings, but which corresponds, for example , to that described and illustrated in the aforementioned EP-1834665A2 axially engages the containment attachment 40 and thus applies an axial grip on the collar 28 so as to drive it towards the outlet passage 7. Due to the interaction between the base 29 of the collar 28 and the conical part 18, the hollow resilient element 15 is thus extended and resiliently deformed, pressing the inner surface of the end wall 20 against the starting end 11 of the inlet part 6 of the tubular member 5. During this step, represented initially in figure 5 and then in figure 6, the inner guide projection 23 of the hollow resilient element 15 moves along the groove 13, starting from the outer enlargement12, until it stops. against the locking step 14 as shown in Figure 6. Simultaneously, an inner annular projection 24 of the hollow resilient element 15 moves downwards, due to the stretch deformation of the part 17 thereof, until it releases the communication between the radial passages 9, 10 and so, between the inlet part 6 and the outlet part 7 of the tubular member 5. During this step, the cut 21 starts to open due to the interaction between the end wall 20 and the outer annular enlargement 12.
    [042] Following the complete opening of the female connector, and further downward displacement of the collar 28 and thus, the guaranteed stretch deformation of the hollow resilient element 15, the additional interaction between the end wall 20 and the annular enlargement 12 produces the complete opening of the cut 21 and, correspondingly, the complete opening of the flow passage between the inlet part 6 and the outlet part 7, as shown in figure 7.
    [043] The controlled stretching of the second cylindrical part 19 of the hollow resilient element 15 avoids, due to the interaction between the internal guide projection 23 and the groove 13, the risk of laceration of the cut 21. Additionally, in the downward translation of the second cylindrical part 19 , up to the limit of the internal guide projection 23 against step 14, the containment provided by the axial attachment 30 of the collar 28 prevents such part 19 from diverging laterally, therefore, ensuring the subsequent correct return to the initial position following the decoupling of the female connector. Furthermore, such a return is not only obtained due to the elastic return of the hollow element 15 to the initial undeformed condition, but also due to the positive action provided by the axial attachment 30. Indeed, the interaction between the free end of the axial attachment 30 and the outer radial flange 22 of end wall 20 safely and reliably restores the closed, undeformed condition of cut 21.
    [044] Thus, the description described above clearly shows that the presence of the axial containment attachment 30 and also of the external groove 13 with the locking step 14 that cooperates with the internal guide projection 23, as well as with the external radial flange 22 and with enlargement 12, allows improved control of the opening and reconnection of the connector according to the invention, thus preventing the risk of malfunction, even in the case of repeated actuations.
    [045] Obviously, the construction details and modalities can vary widely with respect to what has been described and illustrated, without departing from the scope of protection of the present invention, as defined in the claims that follow.
