[0019] According to another aspect of the invention, a method for fluid connection is provided, the method comprising: placing (A) a first connector in contact with (B) a second connector, the first connector comprising: (a) a first hollow connector body having an inner surface and an outer surface including a slot, the first hollow connector body having an orifice through the inner surface and the outer surface; (b) a second hollow connector body having an inner surface and an outer surface including a slot, the second hollow connector body having an orifice through the inner surface and the outer surface; and (c) a fluid transfer member inserted between the first hollow connector body and the second hollow connector body, wherein the fluid transfer member is slidably arranged in the slot of the inner surface of the first hollow body and the second hollow connector body. The fluid transfer member has a first surface facing the inner surface of the first hollow body and a second surface facing the inner surface of the second hollow body, and has a first fluid transfer orifice through the first surface and a second fluid transfer orifice through the first and second surfaces. The fluid transfer member has a first open end and a second closed end, wherein the first open end is in fluid communication with the first fluid transfer orifice but not with the second fluid transfer orifice. When the fluid transfer member is in the first fluid transfer position, it provides a first fluid flow path through the first open end and the first fluid transfer orifice; when the fluid transfer member is in the second fluid transfer position... At the second fluid transfer position, a second fluid flow path is provided through the orifice of the first hollow connector body, the second fluid transfer orifice of the fluid transfer member, and the orifice of the second hollow connector body; the second connector includes: (a') a first hollow connector body having an inner surface and an outer surface including a groove, the first hollow connector body having an orifice passing through the inner surface and the outer surface; (b') a second hollow connector body having an inner surface and an outer surface including a groove, the second hollow connector body having an orifice passing through the inner surface and the outer surface; and (c') a fluid transfer member inserted between the first hollow connector body and the second hollow connector body, wherein the fluid transfer member is slidably arranged inside the first hollow body. The fluid transfer member has a first surface facing the groove of the inner surface of the first hollow body and a second surface facing the groove of the inner surface of the second hollow body, so as to provide slidable movement between a first fluid transfer position and a second fluid transfer position. It also has a first fluid transfer orifice through the first surface and a second fluid transfer orifice through the first and second surfaces. The fluid transfer member has a first open end and a second closed end, wherein the first open end is in fluid communication with the first fluid transfer orifice but not with the second fluid transfer orifice. When the fluid transfer member is in the first fluid transfer position, it provides a first fluid flow path through the first open end and the first fluid transfer orifice.When the fluid transfer member is in the second fluid transfer position, a second fluid flow path is provided through the orifice of the first hollow connector body, the second fluid transfer orifice of the fluid transfer member, and the orifice of the second hollow connector body. The method further includes: contacting the outer surface of the first hollow connector body of the second connector with the outer surface of the second hollow connector body of the first connector to provide a first contact position; twisting the first hollow connector body of the second connector and / or the second hollow connector body of the first connector to provide a second contact position; and providing an activation position, causing the fluid transfer member to slide in the first connector to the second fluid transfer position, while the fluid transfer member in the second connector is in the first fluid transfer position.

Various aspects of the method for handling the fluid may include causing fluid to pass through connectors and / or connector assemblies of any number of connections.
[0021] Advantageously, according to various aspects of the invention, two or more connectors and / or connector assemblies can be connected to extend the number of operations (multiple aseptic connections via the same initial connection). Therefore, the number of potential leak points in the flow path is reduced (no need to replace the manifold, fewer connection points for the same number of connections), and the overall complexity of the manifold is also reduced. Operators can choose to use any number of connector assemblies required by the process without relying on complex arrangements of connectors, catheters, T- and Y-connectors, and external hardware such as valves and / or controllers.
[0022] Preferably, the connector or connector assembly is a genderless connector assembly, i.e., it does not require male and female connector connections. Advantageously, the connector or connector assembly can be connected to another connector or connector assembly, such as the connector assembly described herein, or the connector assembly described in U.S. Patent 10,247,342.
[0023] In a preferred aspect, the method of treating the fluid includes passing the fluid through the connected connector and / or connector assembly.
[0024] All aspects of this invention are also applicable to the application of single-use technology (SUT).
[0025] Each component of the invention will now be described in more detail below, wherein similar components have similar reference numerals.
[0026] Figure 1A and 1BOne aspect of connector 1000 is shown, which includes: (a) a first hollow connector body 100 having an inner surface 110 including a groove 155 and an annular groove 142 for receiving a seal 143 (see also) Figures 5A-5B ) and including a receiving resilient seal 123 (preferably, including a flexible lip 123a; see also Figure 1C (including chamber 123b for the lip margin 123a) and Figures 3A-3B (a) the outer surface 120 of the annular groove 122, the first hollow connector body having an opening 190 (surrounded by annular grooves 143 and 122) through the inner and outer surfaces; (b) the second hollow connector body 200 having an inner surface 210 including a groove 255 and an annular groove 242 for receiving a seal 243 (see also) Figures 5A-5B ) and including a resilient seal 223 (preferably, including a flexible lip 223A; see also Figure 1C (including chamber 223b for the lip border 223A) and Figures 3A-3B The outer surface 220 of the annular groove 222 of the first hollow connector body; the second hollow connector body having an opening 290 (surrounded by annular grooves 243 and 222) through the inner and outer surfaces; the end 125 of the first hollow connector body sealingly contacts the end 225 of the second connector body; and (c) a fluid transfer member 300, which is inserted between the first hollow connector body and the second hollow connector body, wherein the fluid transfer member is slidably arranged in a groove in the inner surface of the first hollow body and a groove in the inner surface of the second hollow body, so as to a first fluid transfer position 1 ( Figure 1A ) and the second fluid transfer position 2 ( Figure 1B The fluid transfer member provides slidable movement between the two surfaces. It has a first surface 310A with a groove facing the inner surface of the first hollow body and a second surface 310B with a groove facing the inner surface of the second hollow body. It also has a first fluid transfer orifice 311 passing through the first surface and a second fluid transfer orifice 322 passing through the first and second surfaces. The fluid transfer member has a first open end 301 and a second closed end 302, wherein the first open end is in fluid communication with the first fluid transfer orifice but not with the second fluid transfer orifice (blocked by the solid wall 313 and the solid segment 314). When the fluid transfer member is in the first fluid transfer position, it provides a first fluid flow path 1A through the first open end and the first fluid transfer orifice. Figure 1A ); and when the fluid transfer member is in the second fluid transfer position, a second fluid flow path 2A is provided through the orifice of the first hollow connector body, the second fluid transfer orifice of the fluid transfer member, and the orifice of the second hollow connector body. Figure 1B ).
[0027] Typically, the first and second hollow connector bodies 100 and 200 are identical, thereby reducing costs.
[0028] After the first connector and the additional (second) connector are connected and the pull bars 520A and 520B are removed, the second fluid transfer position 2 and the second fluid flow path 2A are utilized relative to the first connector (see...). Figure 1A and 1C , among which, Figure 1C In the second connector 2000, the structure marked with "'" corresponds to the structure in the first connector 1000 that does not have "'". The first connector includes an inlet connector 1010 with an air inlet port 1010a to allow the use of the next first fluid transfer position 1' and the next first fluid flow path 1A' relative to the second connector.
[0029] As discussed in more detail below, when the first connector is connected to the second connector, the locking mechanism on the outer surface of the second hollow connector body of the first connector contacts the locking mechanism on the outer surface of the first hollow connector body of the second connector, such that the locking mechanisms are in a first contact position. Preferably, an anti-actuation assembly 500 including at least one peel strip is inserted between the locking mechanisms (more preferably, the anti-actuation assembly includes a sub-assembly 500A associated with one hollow connector body and a sub-assembly 500B associated with another contact hollow connector body), and this assembly is removed. Subsequently, the second hollow connector body of the first connector and / or the first hollow connector body of the second connector are twisted, such that the corresponding resilient seal seals against the hollow connector body at the second contact position (including the actuated position).
[0030] The hollow connector bodies can be interconnected, including using a locking mechanism and rotating from a first contact position to a second contact (actuated or enabled) position, as disclosed in U.S. Patent 10,247,342.
[0031] Any number of connectors and / or connector assemblies can be connected, each additional connector or connector assembly initially utilized with a first fluid transfer location and a first fluid flow path, and utilized via a second fluid transfer location and a second fluid flow path after being connected to a new (additional) connector or connector assembly. Thus, for example, using... Figure 1C and 2CFor reference, an additional (e.g., third) connector may be attached to the outer surface 200' of the second connector 2000 and, after the hollow body is placed in the actuated position, and subsequently after the fluid transfer member 300' is moved to the second fluid transfer position, receive fluid from the second connector along the second fluid flow path, and, when the fluid transfer member in the third connector is in the first position, transfer fluid along the first flow path.
[0032] by Figure 4B-4D Referring to the aspect shown in 5A, the fluid transfer member 300 has pins 315A, 315B that prevent further sliding movement in the grooves 155, 255 in the first and second positions when in contact with the ends 161A, 261A, 162B, 262B of the wall sections 160, 260 in a first position and when in contact with the ends 181A, 281A, 181B, 281B of the wall sections 170, 270, 180, 280 in a second position.
[0033] In a preferred aspect of the connector (see...) Figure 2A 3 (especially), 5A and 5C), the outer surfaces 110 and 220 of the first and second hollow connector bodies each include a corresponding locking mechanism (first locking mechanism 150; second locking mechanism 250), the corresponding locking mechanism including: protrusions 151 and 251 extending above the surface, the protrusions including grooves 152 and 252 and guides 153 and 253; and inclined surfaces 155 and 255 extending below the surface. In some embodiments, the locking mechanism includes guides 153 and 253 on the protrusions and spring arms 159 and 259. Figures 3A-3B In the aspects shown, the first connector body includes first locking mechanisms 150A and 150B, which include protrusions 151A and 151B, grooves 152A and 152B, guides 153A and 153B, bevels 155A and 155B, and spring arms 159A and 159B; the second connector body includes second locking mechanisms 250A and 250B, which include protrusions 251A and 251B, grooves 252A and 252B, guides 253A and 253B, bevels 255A and 255B, and spring arms 259A and 259B. The locking mechanisms are integrally formed with the body, therefore, when the body moves from the first position to the second position, the locking mechanisms will not move separately from the other parts of the body. It should be understood that, for ease of reference, although... Figure 1A , 2AFigures 1 and 3 show locking mechanisms 150, 250 and sub-assemblies 500A, 500B on the outer surfaces of the first and second hollow bodies of the first connector 1000, but when the two connectors are connected together, the locking mechanism of the hollow body of one connector contacts the locking mechanism of the hollow body of the other connector, and the anti-actuation assembly 500 (sub-assemblies 500A, 500B include corresponding strips 520A, 520B) is inserted between the locking mechanisms.
[0034] An anti-actuation component (when present) prevents the formation of an actuating position between the connector or connector assembly, while allowing the formation of an actuating position between the connector or connector assembly when removed. This component, or each sub-assembly, may include a pull ring if desired.
[0035] After removing the anti-actuation component 500, any one or both contact hollow connector bodies can be rotated from the first position such that the bevel of the locking mechanism of one hollow connector body engages with the groove in the protrusion of the locking mechanism of the other hollow connector body, until the hollow body is in the second (actuated) position. Once the hollow connector body is in the actuated position, the interior of the connector body will circulate fluidly through the corresponding coaxially aligned orifices 290, 190', preferably in a sterile manner without any external contamination.
[0036] Optionally, (a) the surface of the bevel and the surface of the groove that will contact the surface of the bevel have an initial angle, and are then leveled such that when the connector body is in the actuated position, the protrusion rests on the horizontal surface, providing the required amount of pressure to the body of the seal, and / or (b) particularly as Figures 3A-3B As shown in Figure 5B, the locking mechanism has spring arms 159 (159A, 159B) and 259 (259A, 259B) that bend to deflect bump guides 153 (153A, 153B) and 253 (253A, 253B). Once the bump has passed, the bump guides return to hold the bump in the actuated position, preferably providing a tactile and / or audible "click" sound simultaneously. Figure 3A For reference, "A" and "B" indicate the position of the spring arm after bending, providing a tactile and / or audible "click" sound.
[0037] In some embodiments, each connector or connector assembly includes an alignment arrangement for mating an anti-actuation component with a first connector hollow body and a second connector hollow body, the alignment arrangement including a protrusion and a recess; wherein the first and second surfaces of the anti-actuation component, the first end of the first hollow connector body, and the first end of the second hollow connector body each have at least one protrusion and / or at least one recess, such that the first surface of the anti-actuation component mates with the first hollow connector body surface, and the second surface of the anti-actuation component mates with the second hollow connector body surface.
[0038] For example, in Figure 3A and 3B In the illustrated aspect, the connector further includes an alignment arrangement structure 800 comprising a recess 801 (illustrated recess having two slots, (801a and 802b)) in a face 110 of a first hollow connector body and a protrusion 810 (shown as having two hooks 810' and a pin 810) on a first surface 511 of an anti-actuation protrusion 501, the protrusion engaging with the recess 801 (wherein the second connector hollow body has the same structure). As described below, in the aspect including the pin, the engagement of the pin with the recess further reduces bending / movement when the sub-assembly engages with the corresponding hollow body.
[0039] If necessary, each sub-assembly 500A, 500B may include a bonding arrangement structure comprising at least one protrusion and at least one recess, such that when the hollow connector bodies are in contact with each other in a first position, the first anti-actuation sub-assembly and the second anti-actuation sub-assembly can mate together. For example, as Figure 5C As shown, subassemblies 500A and 500B include corresponding bonding arrangements 550A and 550B, which include protrusions 551A and 551B and recesses 552A and 552B, wherein protrusion 551A mates with recess 552B, and protrusion 551B mates with recess 551A. Advantageously, this allows the operator to pull any one or both subassemblies and / or any one or both peelable strips 520A and 520B, and to remove the anti-actuation component from the connector or connector assembly, enabling the hollow connector body to be placed in the actuated position.
[0040] In some respects, the integrally formed locking mechanism and anti-actuation components and their operation can be as described in U.S. Patent 10,247,342.
[0041] To improve the sterility of the connector body's interior, the strip (sealing layer) is preferably arranged to cover the opening at the outer surface of the hollow connector body. The strip can have different configurations. Typically, the strip is attached (e.g., welded, captured, or clamped) to the anti-actuation component protrusion and / or the surface of the hollow connector body. Preferably, the strip is attached to the corresponding sub-component protrusion and the hollow connector body surface (also covering the seal and contacting the sealing lip). In many embodiments, the strip may also cover all or at least a portion of the face seal without being attached to the seal. For example, each strip may completely cover at least the seal closest to the opening. The strip may not be attached to the seal itself, but may be attached to the surface of the face surrounding each seal.
[0042] The release strip may be made of an impermeable material or a permeable material that resists the passage of contaminants, including bioinhibitors. These materials include, but are not limited to, elastic sheets, polymer films, and metal foils, such as aluminum foil, any of which may further include reinforcing materials. Furthermore, the release strip may be coated and / or impregnated with a biocide. Preferably, the release strip is a sterile porous or microporous membrane that allows steam to pass through during autoclaving and has a minimum tensile strength of about 60 N in some respects.
[0043] Any of a variety of seals can be provided on the surface, including, for example, gaskets, resilient sealing members, or O-rings. Preferably, the seal comprises soft rubber or thermoplastic elastomer (TPE) (e.g., Shore A hardness of about 50 to about 65). Flexible sealing lips 123A, 223A (if present) help prevent environmental contaminants from entering the connector assembly when the anti-actuation component is removed. Because the lips can bend and spring back, the stripper strip can be removed with less force, and the lips can quickly close the gap. When the hollow connector body moves (e.g., twists) to the actuation position, the flexible lips 123a, 223a (preferably narrow) quickly fold into recesses in each hollow connector body surface (123b, 223b), where the lips and sealing bodies (sealing rhombuses) contact each other, providing a more robust face seal. The contact between the rhombuses provides a face-to-face seal, preventing fluid leakage even under increased pressure (e.g., pressures up to about 4 barg).
[0044] In another aspect, a connector assembly is provided, including one aspect of the connector, further comprising: a first removable cover engaging with a first hollow connector body, wherein a removable anti-actuation component is inserted between the first removable cover and the first hollow connector body, the first removable cover covering an outer surface of the first hollow connector body; and a second removable cover engaging with a second hollow connector body, wherein a removable anti-actuation component is inserted between the second removable cover and the second hollow connector body, the second removable cover covering an outer surface of the second hollow connector body.
[0045] To prevent accidental removal or damage to the stripper strip, each connector body may further include a removable cover that at least covers a large portion of the stripper strip and a first end of the connector body. The cover may be fitted onto the connector body at the first end, for example, via a friction fit or a snap-fit, and may have any of a variety of different configurations. For example, as... Figure 7A and 7BAs shown, each cover 600 (the cover 700 on the second connector assembly will have the same structure) may have a rigid top 601 protecting at least a portion of the stripping strip and a skirt 602 fitted along the edge of the connector bodies 100, 200. The cover 600 may also include a handle 610 as part of the skirt or a handle extending axially below the skirt 602. Preferably, as Figure 7B As shown, the cover includes a tear strip 615 having a tear strip handle 616 to allow an operator to grasp the tear strip handle and tear the tear strip, making it easier to remove the cover from the connector body. A peel strip 520 (520A) can be axially bent under 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 tear strip handle can be used to lift the cover 600 from the connector body 100 and also to prevent unintentional manipulation of the anti-actuation component protrusion 501 and / or the peel strip.
[0046] The connectors and the components of the connector assembly can be sterilized in a manner known in the art (e.g., autoclaving, gamma irradiation, etc.).
[0047] The connector and its components can be formed from a variety of materials. For example, any one or more of the following—the hollow connector body, locking mechanism, anti-actuation component, and cover—can be made of any metallic and / or polymeric material compatible with the fluid that will flow through the connector assembly. Preferably, the connector body, locking mechanism, and cover are made of a polymeric material, which may include, but is not limited to, one or more of polycarbonate, polypropylene, polystyrene, polyvinyl chloride, polyethersulfone, polyvinylidene fluoride, or polysulfone. For some embodiments, transparent or translucent polymeric materials may be selected. Typically, the hollow body, hollow tube, protrusion, and connector body cover are formed of rigid injection-molded plastic, preferably BPA-free plastics such as polyethersulfone (PES), polycarbonate (PC), polysulfone (PSU), and polybutylene terephthalate (PBT), while the cover is made of low-density injection-molded plastic, such as TPE or polypropylene (PP).
[0048] These components can be manufactured in various ways, including molding, machining, pressing and stamping, and can be shaped into sub-assemblies.
[0049] Alternatively or additionally, certain components according to various aspects of the invention may be integral, for example, manufactured by additive manufacturing (sometimes referred to as "additive layer manufacturing" or "3D printing"). They are typically formed by repeatedly depositing metal powder bonded together with an activatable binder (e.g., binder jetting, sometimes also referred to as "droplet deposition on powder"), typically followed by agglomeration of the powder, for example, by sintering. Certain components may be manufactured together substantially simultaneously in a continuous operation via additive manufacturing.
[0050] Any suitable additive manufacturing equipment can be used, and various production 3D printers are suitable and available on the market.
