DETAILED DESCRIPTION

[0013] According to one aspect of the present invention, a connector is provided, comprising: (a) a hollow connector body having a bottom surface and an inner wall forming a central hole extending through the bottom surface; the inner wall having at least two resilient fingers, each of the at least two resilient fingers having an upper end with an inwardly facing protrusion; and (b) a hollow tube retained in the central hole of the hollow connector body, the hollow tube having an open first end, an open second end, and a longitudinal axis, the second end having a lower portion including the central hole and including a lower portion ring shaped groove, the lower annular groove includes an elastic deformable annular seal arranged in the lower annular groove and surrounding the central hole; the hollow tube includes at least an upper groove, an intermediate groove and a lower groove spaced apart along the longitudinal axis, the lower groove includes a second elastic annular seal arranged in the lower groove, thereby sealing a portion of the inner wall of the hollow connector body; wherein the inwardly facing protrusions of the at least two elastic fingers of the hollow connector body are inserted into the upper groove of the hollow tube, so that the hollow tube can rotate in the central hole without rotating the hollow connector body.

[0014] In one aspect of the connector, each of the resilient fingers includes an inwardly facing shoulder a distance from the upper end, and in a preferred aspect, the intermediate groove has a lower wall that contacts the inwardly facing shoulder on each of the at least two resilient fingers.

[0015] In some aspects, the resilient annular seal disposed in the lower annular groove has a flexible lip.

[0016] On the other hand, a connector assembly comprises: an aspect of the connector, wherein the bottom surface of the hollow connector body (preferably, the bottom surface is aligned with the lower portion of the second end of the hollow tube) includes an integrally formed locking mechanism, the integrally formed locking mechanism including at least one lug with a narrow slot, and at least one ramp; and an anti-actuation assembly engagement portion, the anti-actuation assembly engagement portion including at least one recess and / or at least one protrusion; a removable anti-actuation assembly, the removable anti-actuation assembly including at least one peel strip and at least one recess and / or at least one protrusion, the at least one recess and / or at least one protrusion of the removable anti-actuation assembly engaging with the anti-actuation assembly engagement portion of the hollow connector body; and a removable cap, the removable cap engaging with the hollow connector body, wherein the removable anti-actuation assembly is inserted between the removable cap and the hollow connector body, and the removable cap covers the bottom surface of the hollow connector body.

[0017] According to another aspect of the present invention, a method for making a fluid connection is provided, the method comprising: (a) in a first position, placing the bottom surface of a first hollow connector body of a first connector assembly in contact with the bottom surface of a second hollow connector body of a second connector assembly, the first connector assembly comprising a first rotatable hollow tube, the first rotatable hollow tube comprising an elastically deformable annular seal arranged in an annular groove, wherein the first rotatable hollow tube is retained in a central hole of the first hollow connector body, wherein the bottom surface of the first hollow connector body further comprises a first locking mechanism integrally formed with the bottom surface of the first hollow connector body, the first locking mechanism comprising at least one lug with a narrow slot, and at least one ramp, the second connector assembly comprising a second rotatable hollow tube, the second rotatable hollow tube comprising an elastically deformable annular seal arranged in an annular groove and (b) twisting the first hollow connector body and / or the second hollow connector body so that in a second position, the first locking mechanism engages with the second locking mechanism, the first elastic deformable seal seals the first hollow tube in the annular groove surrounding the center hole of the first hollow connector body, and the second elastic deformable seal seals the second hollow tube in the annular groove surrounding the center hole of the second hollow connector body, the second position comprising an actuated position.

[0018] Aspects of the method may also include removing an anti-actuation assembly after (a) (the first position) and before (b) (the second position), wherein the anti-actuation assembly includes at least one peel-off strip (preferably two peel-off strips) inserted between the bottom surface of the first hollow connector body and the bottom surface of the first body of the second hollow connector.

[0019] On the other hand, a method for handling fluid is provided, the method comprising: (a) in a first position, placing the bottom surface of a first hollow connector body of a first connector assembly in contact with the bottom surface of a second hollow connector body of a second connector assembly, the first connector assembly comprising a first rotatable hollow tube, the first rotatable hollow tube comprising an elastically deformable annular seal arranged in an annular groove, wherein the first rotatable hollow tube is retained in a central hole of the first hollow connector body, wherein the bottom surface of the first hollow connector body further comprises a first locking mechanism integrally formed with the bottom surface of the first hollow connector body, the first locking mechanism comprising at least one lug with a narrow groove, and at least one ramp, the second connector assembly comprising a second rotatable hollow tube, the second rotatable hollow tube comprising a second elastically deformable annular seal arranged in an annular groove, and (b) twisting the first hollow connector body and / or the second hollow connector body so that in a second position, the first locking mechanism engages with the second locking mechanism, the first elastic deformable seal seals the first hollow tube in the annular groove surrounding the center hole of the first hollow connector body, and the second elastic deformable seal seals the second hollow tube in the annular groove surrounding the center hole of the second hollow connector body, the second position including an actuated position; and transferring fluid through the first connector assembly and the second connector assembly.

In some aspects, the first anti-actuation subassembly and the second anti-actuation subassembly mate together when the first hollow connector body and the second hollow connector body contact each other in a first position.

[0021] Advantageously, even when using conduit having a large diameter (e.g., 3 / 4 inch is larger) and / or braiding to make the conduit rigid and inflexible, because the hollow tube can rotate independently of the hollow connector body, fluid connections can be made independent of the orientation of the device to which the connector is connected.

[0022] Aspects of the present invention are particularly well-suited for single-use technology (SUT) applications. Preferably, the connector assembly is a hermaphroditic connector assembly, i.e., does not require a hermaphroditic connection. Advantageously, the connector assembly can be connected to another connector assembly, for example, as described herein or as described in U.S. Patent No. 10,247,342.

[0023] Each component of the present invention will now be described in more detail below, wherein like components have like reference numerals.

[0024] use Figure 1 For reference, the illustrated aspects include a connector assembly 1000 comprising a hollow connector body 100 having a top surface 110 and a bottom surface 120, a rim 119 and a central hole 190 passing through the top and bottom surfaces, a rotatable hollow tube 300 being retained in the central hole, the hollow tube having a longitudinal axis A, the tube body extending from an open first end 301 to an open second end 302, the open second end having a lower portion 303 including a tube central hole 121, the hollow tube including an elastically deformable annular seal 130 having a central opening 131 and an outer flexible lip 132, wherein the seal 130 is arranged in an annular groove 122 in the lower portion of the tube, the annular groove concentrically surrounding the tube central hole 121.

[0025] exist Figure 1 、 Figures 2A to 2B 、 Figures 3A to 3B and Figure 5A In the illustrated aspects, the hollow connector body 100 has an inner wall 199 forming a central hole 190 extending from the top surface through the bottom surface; the inner wall has a plurality of resilient fingers 175, each of which has an upper end 176 with an inwardly facing protrusion 176A. In these illustrated aspects, each resilient finger includes an inwardly facing shoulder 177 at a distance from the upper end that contacts a portion of the lower surface 312a of the intermediate recess 312 of the tube, thereby helping to prevent the tube from being fully inserted into the hollow connector body (see Figure 2B In aspects including a shoulder, the distance of the shoulder from the upper end can be determined by one skilled in the art.

[0026] If desired, the top surface of the connector body may include one or more blades 125 for insertion into slots in the cover 180 .

[0027] exist Figure 1 、 Figures 2A to 2B 、 Figures 3A to 3B and Figure 4 In the illustrated aspect, the hollow tube 300 includes at least an upper groove 311, an intermediate groove 312, and a lower groove 313 spaced apart along the longitudinal axis, the lower groove including a second elastic annular seal 313A disposed therein, thereby sealing a portion 199A of the inner wall 199 of the hollow connector body (see FIG. Figure 2B ); wherein the inwardly facing protrusion of the elastic finger-shaped member of the hollow connector body is inserted into the upper groove of the hollow tube (see Figures 2A to 2B 、 Figures 3A to 3B ), so that the hollow tube can be rotated in the center hole without rotating the hollow connector body. Figure 2B In the illustrated aspect, the intermediate recess 312 has a lower surface 312a that is contacted by the shoulder 177. Once fully inserted into the hollow connector body, similar to the aspect including the shoulder 177 contacting the surface 312a, the inserted protrusion helps prevent the tube from moving downward, and the inserted protrusion and shoulder still allow the hollow tube to be rotated within the central bore without rotating the hollow connector body.

[0028] The bottom surface 120 of the connector body 100 includes a locking mechanism 150. In some aspects, the first connector assembly 1000 and the second connector assembly 2000 have the same structure and are coupled to each other by corresponding identical locking mechanisms (see, for example, Figure 8A and Figure 8B ). However, in other aspects, a connector assembly according to an aspect of the present invention may be coupled to a different connector assembly, for example, as disclosed in US Pat. No. 10,247,342.

[0029] Illustratively with respect to the same structure, the connector assembly 2000 includes a hollow connector body 200, wherein the connector body 200 has a top surface 210 and a bottom surface 220, a rim 219 and a central hole 290, in which a rotatable hollow tube 300 is retained, the hollow tube having a longitudinal axis A, an open first end 301, an open second end 302, the open second end having a lower portion 303 including a tube central hole 221, the hollow tube including an elastically deformable annular seal 230 having a central opening 231 and an outer flexible lip 232, wherein the seal 230 is arranged in an annular groove 222 in the lower portion of the tube, the annular groove concentrically surrounding the tube central hole 221.

[0030] The connector bodies 100, 200 can be connected by (using Figure 5BFor reference, the respective locking mechanisms (first locking mechanism 150; second locking mechanism 250) are coupled to each other at their bottom surfaces 120, 220, and include: lugs 151, 251 extending above the bottom surface, the lugs including slots 152, 252, guides 153, 253, recesses 154, 254; and ramps 155, 255 extending below the bottom surface. In some embodiments, the locking mechanisms each include a guide 153, 253 on the lugs, and an arm 159, 259. Figure 5B In the illustrated embodiment, the first connector body 100 includes a first locking mechanism 150A, 150B, which includes lugs 151A, 151B, slots 152A, 152B, guides 153A, recesses 154A, ramps 155A, 155B, and arms 159A, 159B; and the second connector body includes a second locking mechanism 250A, 250B, which includes lugs 251A, 251B, slots 252A, 252B, guides 253A, recesses 254A, ramps 255A, 255B, and arms 259A, 259B. The locking mechanism is integrally formed with the body, and therefore, when the body moves from a first contact position to a second contact (actuated) position, the locking mechanism does not move separately from the rest of the body.

[0031] As will be discussed in more detail below after removing the anti-actuation assembly 500, one or both of the hollow connector bodies can be rotated from the first contact position such that the ramps of the locking mechanism of one hollow connector body engage the slots in the lugs of the locking mechanism of the other hollow connector body until the two hollow connector bodies are in a second contact (actuated (or activated)) position. In a preferred aspect, after providing the second contact position, the fluid is processed by passing the fluid through the first hollow connector body and the second hollow connector body.

[0032] The hollow connector bodies can be coupled to each other, including using a locking mechanism and rotation from a first contact position to a second contact (actuated) position, as disclosed in US Patent 10,247,342.

[0033] Once the hollow connector body is in the actuated position, the interiors of the hollow connector bodies are in fluid communication with each other through the coaxially aligned holes 121 , 221 , preferably in a sterile manner without any external contamination.

[0034] Alternatively, as Figure 8A and Figure 8BAs shown, (a) the surface of the ramp, and the surface of the slot that will contact the surface of the ramp, have an initial angle and then reach a level so that when the connector body is in the actuated position, the lug rests on the level surface, thereby providing a desired amount of pressure on the body of the seal, and / or (b) as shown Figure 5B In particular, the locking mechanism is shown having arms 159 (159A, 159B), 259 (259A, 259B) which lock the lug guides 153 (153A), 253 (253A) into the recesses 154 (154A), 254 (254A) once the lugs have passed, thereby holding the lugs in the actuated position to prevent disconnection.

[0035] Figure 1 The illustrated embodiment of the connector assembly 1000 also includes a removable anti-actuation assembly 500 comprising a tab 501 having a first surface 511 (facing the first hollow connector first body end) and a second surface 512 (facing the second hollow connector first body end), and a peel strip 520 interposed between the first hollow connector first body end and the second hollow connector first body end, wherein the anti-actuation assembly, when present, prevents the connector assembly from being in an actuated position when the first and second hollow connector bodies are in contact with each other in a first position, and allows the connector assembly to be in an actuated position when removed. The tab may include a pull ring, if desired.

[0036] In some aspects, the integrally formed locking mechanism and anti-actuation assembly and their operation may be as described in US Patent 10,247,342.

[0037] When necessary, the connector assembly may include an alignment device for mating the anti-actuation assembly with the first connector hollow body and the second connector hollow body, the alignment device including a protrusion and a recess; wherein the first surface and the second surface of the anti-actuation assembly, the bottom surface of the first hollow connector and the second hollow connector bottom surface each have at least one protrusion and / or at least one recess, so that the first surface of the anti-actuation assembly mates with the end of the first body of the first hollow connector, and the second surface of the anti-actuation assembly mates with the end of the first body of the second hollow connector.

[0038] For example, in Figure 5B 、 Figure 5C 、 Figure 7A and Figure 7BIn the illustrated aspect, the connector further includes an alignment arrangement 800 comprising a recess 801 in an exterior portion of the first hollow connector body (the recess shown is illustrated with two slots 801a, 801b) and a protrusion 810 (illustrated as having two hooks 810' and a pin 810") on a first surface 511 of the anti-actuation tab 501, the protrusion being engageable with the recess 801 (wherein the second connector hollow body has the same structure). In the aspect including the pin, the engagement of the pin with the recess further reduces flexure / movement when the subassembly is engaged with the corresponding hollow body.

[0039] In some aspects, for example, Figure 5B 、 Figure 5C 、 Figure 7A and Figure 7B As shown, the anti-actuation assembly 500 includes: a first anti-actuation subassembly 500A, the first anti-actuation subassembly including a subassembly tab 501A having a first surface 511, and a first peel strip 520A; and a second anti-actuation subassembly 500B, the second anti-actuation subassembly including a subassembly tab 501B having a second surface 512, and a second peel strip 520B. If desired, each subassembly may include a keying device including at least one protrusion and at least one recess so that the first anti-actuation subassembly and the second anti-actuation subassembly can be mated together when the first hollow connector body and the second hollow connector body contact each other in the first position. For example, as Figure 5C 1A, subassembly tab 501A is shown having a second surface 521A including a keying arrangement 550A including a protrusion 551A and a recess 552A, and subassembly tab 501B having a second surface 522B including a keying arrangement 550B including a protrusion 551B and a recess 552B, wherein protrusion 551A can mate with recess 552B and protrusion 551B can mate with recess 551A. Advantageously, this allows an operator to pull on either or both tabs 501A, 501B and / or either or both peelable strips 520A, 520B and remove the anti-actuation assembly from the connector assembly, allowing the hollow connector body to be placed in an actuated position.

[0040] In order to enhance the sterility of the interior of the connector body, the peel strip (seal layer) is preferably arranged to cover the opening at the first end of the connector body. The peel strip can be configured differently. Typically, the peel strip is coupled (e.g., welded, clamped or clamped) to the anti-actuation assembly tab and / or the face of the hollow connector body. Preferably, the peel strip is coupled to the corresponding subassembly tab and the hollow connector body face (also covering the seal and contacting the seal lip). For many embodiments, the peel strip can also cover all or at least a portion of the face seal without being coupled to the seal. For example, each peel strip can completely cover at least the seal closest to the opening. The peel strip can be coupled not to the seal itself but to the surface of the face surrounding each seal.

[0041] The stripping strip can be made of a permeable or impermeable material that prevents contaminants (including biological contaminants) from passing through. These materials include, but are not limited to, elastomeric sheets, polymer films, and metal foils (e.g., aluminum foil), any of which may also include reinforcing materials. In addition, the stripping strip can be coated with and / or impregnated with an antimicrobial agent. Preferably, the stripping strip is a sterile porous or microporous membrane that allows steam to pass through during autoclaving and, in some aspects, has a minimum tensile strength of about 60N.

[0042] Any of a variety of seals can be provided on the face, including, for example, a gasket, an elastic sealing member, or an O-ring. Preferably, the seal comprises a soft rubber or thermoplastic elastomer (TPE) (e.g., having a Shore A durometer of about 50 to about 65). Preferably, the seal can include a flexible seal lip that helps prevent environmental contaminants from entering the connector assembly when the anti-actuation assembly is removed. Because the lip is flexible and resilient, the peel-off strip can be removed with less force, and the lip can quickly close the gap. When the hollow body is moved (e.g., twisted) to the actuated position, the flexible lip (preferably narrow) can quickly fold into an optional recess in each hollow tube, where both the lip and the seal body (seal lozenge) contact each other, providing a more secure face seal. The contact between the seal lozenges provides a face-to-face seal that prevents fluid leakage even under increased pressure (e.g., pressures up to about 4 barg).

[0043] If desired, the first hollow connector body may include a first connector outer surface (eg, as a cover 180 and / or rim 119 on the first hollow connector body (see Figure 1 and Figure 8A ) portion), the first connector outer surface also includes a first external connector alignment indicator 900a; and the second hollow connector body includes a second connector outer surface (e.g., as a cover 280 and / or rim 219 on the second hollow connector body (see Figure 8A ) part), the second connector outer surface also includes a second external alignment indicator 900b; when the first hollow connector body and the second hollow connector body are in the first position, the first external alignment indicator and the second external alignment indicator are not aligned, and when the first hollow connector body and the second hollow connector body are in the second (actuated) position, the first alignment indicator and the second alignment indicator are aligned.

[0044] To prevent inadvertent removal or damage of the peel strip, each connector body may also include a removable cap that covers at least a majority of the peel strip and the first end of the connector body. The cap may be assembled to the connector body at the first end, for example, by a friction fit or a snap fit, and may have any of a variety of configurations. For example, Figure 1 、 Figure 6A 、 Figure 6B and Figure 7B As shown, each cap 600 (the cap 700 on the second connector assembly will have the same structure) can have a rigid top 601 that protects at least a portion of the peel strip, and a skirt 602 that fits along the edge 119 of the connector body 100. The cap 600 can also include a handle 610 that extends axially as part of the skirt or below the skirt 602. Preferably, as shown in FIG. Figure 1 and Figure 6B As shown, the cap includes a tear strip 615 having a tear strip handle 616, thereby allowing an operator to grasp the tear strip handle and tear the tear strip, thereby allowing the cap to be more easily removed from the connector body. The peel strip 520 (520A) can be axially bent below the handle 610, and the handle can extend along all or at least a portion of the peel strip 520 (520A). The handle, tear strip and / or processed tear strip can be used to lift the cap 600 from the connector body 100 and can also prevent inadvertent manipulation of the anti-actuation assembly tab 501 and / or the peel strip.

[0045] The components of the connector assembly can be sterilized as known in the art (e.g., autoclaving, gamma irradiation, etc.)

[0046] The components of the connector assembly can be formed from a variety of materials. For example, one or more of the following can be made of any metal material and / or polymer material that is compatible with the fluid that will flow through the connector assembly: the hollow connector body, the hollow tube, the connector body cover, the locking mechanism, the tab, and the cap. Preferably, the connector body, the hollow tube, the locking mechanism, and the cap are made of a polymer material, and the polymer material may include, but is not limited to, one or more of polycarbonate, polypropylene, polystyrene, polyvinyl chloride, polyethersulfone, polyvinylidene fluoride, or polysulfone. For some embodiments, a transparent or translucent polymer material can be selected.
