Description

[Technical Field]

[0001] The present disclosure relates generally to medical fluid connectors, and more particularly to a fluid connector system having valve assemblies that can be coupled together to form a fluid pathway. [Background technology]

[0002] Medical connections are widely used in fluid delivery systems, such as those used in connection with intravenous (IV) fluid lines, blood access, hemodialysis, peritoneal dialysis, enteral nutrition, drug vial access, and other procedures.

[0003] In some cases, medical connections can become unintentionally disconnected or detached. For example, medical tubing of an IV set connected to a catheter can become disconnected if unintended or unexpected forces are applied to the catheter that may exceed the design limits of the catheter securement method. Unintended or unexpected forces can be applied to the tubing and / or catheter when a patient moves or turns in bed, or when the tubing or another portion of the intravenous set gets caught on a part of the bed such as a handrail, or when a patient is panicked, confused, or mentally unstable enough that the medical tubing is unintentionally or intentionally pulled from the patient or from medical equipment connected to the tubing. Summary of the Invention [Problem to be solved by the invention]

[0004] In accordance with at least some embodiments disclosed herein, it is recognized that the unintended disconnection or severance of a medical connection, such as a medical fluid line, can result in injury to the patient or caregiver, such as by depriving the patient of medication, increasing the likelihood of infection for the patient, and exposing the caregiver to harmful medications. [Means for solving the problem]

[0005] Accordingly, aspects of the present disclosure provide a connector comprising: a connector housing comprising a connector body defining a housing interior space, a luer opening, and a valve opening, wherein the housing interior space is in fluid communication with the luer opening and the valve opening; a luer portion comprising a luer end and a housing end, the luer portion defining a lumen extending between the luer end and the housing end, the housing end of the luer portion extending through the luer opening of the connector body to couple the luer portion to the connector housing, the lumen being in fluid communication with the housing interior space; and a first connector portion comprising a deformable valve member disposed within the housing interior space and comprising a spherical portion extending partially through the valve opening, the spherical portion defining a slit, the deformable valve member configured to selectively prevent fluid flow from the housing interior space through the valve opening and to deform to widen the slit and allow fluid flow from the housing interior space through the valve opening.

[0013] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject technology. It should be understood that the subject technology may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail in order to avoid obscuring the subject technology.

[0014] Furthermore, while the present description sets forth specific details of various embodiments, it will be appreciated that the description is illustrative only and should not be construed as limiting in any way. In addition, while particular embodiments of the present disclosure may be disclosed or illustrated in the context of an IV set, it is contemplated that such embodiments may be used in other fluid delivery systems. Still further, various applications of and modifications to such embodiments that may occur to those skilled in the art are also encompassed by the general concepts described herein.

[0015] According to several embodiments, the present application discloses various features and advantages of a fluid connector system. The fluid connector system can provide efficient and safe maintenance of fluid connections, such as connections used to transfer medical fluids to or from a patient. The fluid connector system can maintain a fluid path by resisting unintended disconnection when a pulling or tension force is applied to the fluid connector system, such as when the patient moves or when medical tubing is pulled from the patient.

[0016] The fluid connector system can also prevent injury to the patient or caregiver by allowing disconnection or separation between portions of the connector system when a tensile or tension force exceeds a threshold. The fluid connector system can also prevent injury to the patient or caregiver by blocking the fluid pathway when disconnection or separation occurs between portions of the connector system. Furthermore, the fluid connector system can provide efficient and safe re-establishment of the fluid pathway by allowing reassembly of portions of the system after a disconnection or separation occurs. Advantageously, the fluid connectors described herein can prevent blood loss, loss of IV fluids, infection, and / or delays in medication delivery. In some applications, the design of the fluid connector can facilitate effective cleaning and disinfection of the components. Furthermore, in some applications, the connectors described herein can be manufactured at a relatively low cost.

[0017] Referring now to the figures, Figure 1 illustrates an example of a fluid connector 100 in use, according to an embodiment of the present disclosure. The connector system 100 is coupled to the tubing of an IV set that is being used to direct fluid to a patient 10. The IV set may include a medication bag 12, a drip chamber 14, tubing 16, and an IV catheter 18.

[0018] The connector system 100 fluidly connects the tubing 16 to the IV catheter 18. While the connector system 100 is illustrated as being coupled along the fluid path of an IV set between the medication bag 12 and the patient 10, it should be understood that the connector system 100 may be connected within other fluid paths, such as between a patient and an IV pump or between a patient and a dialysis machine. The connector system 100 may also be connected along another portion of the fluid path. For example, the connector system 100 may be connected along a proximal portion of the fluid path, such as between the tubing 16 and the medication bag 12 or other fluid therapy device. In another example, either the first or second portion of the fluid connector 100 may be directly coupled to another fluid delivery device, such as a catheter or a medication bag.

[0019] 2 illustrates a perspective view of a fluid connector 100 according to an embodiment of the present disclosure. Referring to FIG. 2, the fluid connector 100 provides a fluid pathway to a patient while allowing for a "fusible link," or rapid disconnect, allowing for controlled disconnection of the fluid connector 100 if excessive force is applied. As described herein, the fluid connector 100 may allow for controlled disconnection at a predetermined level of force to prevent accidental removal of the catheter from the patient.

[0020] FIG. 3 illustrates a perspective view of connector portions 110, 150 of the fluid connector 100 of FIG. 2 according to an embodiment of the present disclosure. FIG. 4A illustrates a cross-sectional view of the separated fluid connector 100 of FIG. 2 according to an embodiment of the present disclosure. FIG. 4B illustrates a cross-sectional view of the connected fluid connectors 100 of FIG. 2 according to an embodiment of the present disclosure. With reference to FIGS. 2-4B, the fluid connector 100 provides a fluid flow path or a fluid pathway from one end of the fluid connector 100 to the opposite end of the fluid connector 100. As illustrated, the fluid connector 100 includes a first connector portion 110 and a second connector portion 150 coupled together to form a fluid pathway.

[0021] FIG. 5 is an exploded perspective view of the first connector portion 110 of the fluid connector 100 of FIG. 2 according to an embodiment of the present disclosure. Referring to FIGS. 2-5, the first connector portion 110 allows fluid flow to or from a patient or any other portion of an IV set. In the illustrated example, the first connector portion 110 includes a luer portion 120 to allow the first connector portion 110 to be connected to a mating luer connector. As illustrated, the mating luer connector can be attached to luer threads 122. Fluid can pass to and from the fluid connector 100 through the mating luer connector via a lumen 126 defined in the luer portion 120. In the illustrated example, the luer portion 120 can be coupled to other portions of the first connector portion 110. In some embodiments, the housing end 124 of the luer portion 120 can be coupled to the luer end 143 of the connector housing 140. Optionally, housing end 124 of luer portion 120 may define a ridge 125. As illustrated, ridge 125 may engage a groove 141 defined at or near luer end 143 of connector housing 140 to define a snap fit or joint between luer portion 120 and connector housing 140 to selectively couple luer portion 120 and connector housing 140.

[0022] FIG. 6 is an exploded perspective view of the second connector portion 150 of the fluid connector 100 of FIG. 2 according to an embodiment of the present disclosure. Referring to FIGS. 2-4B and 6, the second connector portion 150 allows fluid flow to and from a fluid source or any other portion of an IV set. In the illustrated example, the second connector portion 150 includes a connector housing 170 that allows the second connector portion 150 to be connected to a fluid source or other portion of an IV set. Tubing or a connector can be received in an opening 173 in the connector housing 170.

[0023] 2-6 , connector housing 140 of first connector portion 110 and connector housing 170 of second connector portion 150 may be coupled together to allow flow between first connector portion 110 and second connector portion 150. In the illustrated example, connector surface 144 of connector housing 140 may define a valve opening 148 that is in fluid communication with the housing interior space and lumen 126 of luer portion 120. Similarly, connector surface 174 of connector housing 170 may define a valve opening 178 that is in fluid communication with the housing interior space and with tubing or other IV set components that are coupled to opening 173 of connector housing 170. Optionally, connector surfaces 144, 174 may be flat or featureless to facilitate cleaning and disinfection. As illustrated in FIG. 4B, when the first connector part 110 and the second connector part 150 are connected together, fluid can flow between the valve opening 148 of the first connector part 110 and the valve opening 178 of the second connector part 110, allowing flow between the first connector part 110 and the second connector part 150.

[0024] In the illustrated example, first connector portion 110 and second connector portion 150 may be engaged to secure or hold first connector portion 110 and second connector portion 150 together. As illustrated, first connector portion 110 and second connector portion 150 may be coupled together by inserting a portion of first connector portion 110 into second connector portion 150. In the illustrated example, connector housing 140 of first connector portion 110 includes or defines ridge 146. As illustrated, ridge 146 extends radially outward from connector body 142. Optionally, ridge 146 may be located axially adjacent connector surface 144 that defines valve opening 148. Similarly, connector housing 170 of second connector portion 150 defines groove 176. Optionally, groove 176 may be located axially adjacent connector surface 174 that defines valve opening 178. In operation, ridge 146 of first connector part 110 can engage groove 176 of second connector part 150 to couple first connector part 110 and second connector part 150 together.

[0025] In the illustrated example, groove 176 and the circumferential wall of connector body 172 engage ridge 146 of first connector portion 110 to resist movement of first connector portion 110 and second connector portion 150 away from each other. The engagement of groove 176 with ridge 146 may define a snap fit or snap joint between first connector portion 110 and second connector portion 150 in some instances of the present disclosure.

[0026] Although groove 176 is configured to resist separation between first connector portion 110 and second connector portion 150, groove 176 and / or ridge 146 are also configured to allow separation between first connector portion 110 and second connector portion 150 when a force exceeding a threshold force is applied between first connector portion 110 and second connector portion 150. In some embodiments of the present disclosure, the threshold force for separation between first connector portion 110 and second connector portion 150 is approximately 2.27 kg (5 pounds) (22.25 Newtons) or greater. Separation between first connector portion 110 and second connector portion 150 can occur when groove 176 and / or the circumferential wall of connector body 172 are biased or deflected away from ridge 146. In the illustrated example, first connector portion 110 and second connector portion 150 can be separated from one another while maintaining the ability to reconnect first connector portion 110 and second connector portion 150 together. In some embodiments, the resistance or force to assembly and separation between first connector portion 110 and second connector portion 150 can be configured such that the force required to assemble first connector portion 110 and second connector portion 150 is less than the force required to separate first connector portion 110 and second connector portion 150.

[0027] In the illustrated example, first connector portion 110 and second connector portion 150 each include a valve member 130, 160, respectively, for controlling flow through connector 100. In particular, valve members 130, 160 allow fluid to flow between first connector portion 110 and second connector portion 150 when first connector portion 110 and second connector portion 150 are connected, and prevent fluid flow when first connector portion 110 and second connector portion 150 are disconnected.

[0028] In the illustrated example, first connector portion 110 includes a valve member 130 disposed within a housing interior space defined by a connector body 142. As illustrated, valve body 132 can selectively restrict or block flow through connector body 142 and / or valve opening 148. In operation, valve body 132 can be moved, deflected, or deformed to allow flow through connector body 142 and valve opening 148. Valve body 132 can be formed from an elastomeric material to allow elastic deformation of valve body 132.

[0029] In some embodiments, the valve body 132 can define a bulbous portion 133 for selectively sealing, restricting, or otherwise blocking flow through the valve opening 148. As illustrated, the bulbous portion 133 can expand, seal, or engage against the connector body 142 to seal or block the valve opening 148. The bulbous portion 133 can be moved, deflected, or deformed to allow flow through the connector body 142 and the valve opening 148. The bulbous portion 133 can include any portion of a sphere and can define a hemisphere.

[0030] As illustrated, the valve body 132 may define a slit 136 for selectively allowing flow through the valve member 130 and the valve opening 148. In a first position, the edges of the slit 136 may come together to resist fluid flow through the valve body 132 and block the valve opening 148. In a second position, the edges of the slit 136 may be spread apart to allow flow through the valve member 130 and through the valve opening 148.

[0031] Similarly, second connector portion 150 includes a valve member 160 disposed within a housing interior space defined by a connector body 172. As illustrated, valve body 162 can selectively restrict or block flow through connector body 172 and / or valve opening 178. In operation, valve body 162 can be moved, deflected, or deformed to allow flow through connector body 172 and valve opening 178. Valve body 162 can be formed from an elastomeric material to allow elastic deformation of valve body 162.

[0032] In some embodiments, the valve body 162 may define a spherical portion 163 for selectively sealing, restricting, or otherwise blocking flow through the valve opening 178. As illustrated, the spherical portion 163 may expand, seal, or engage against the connector body 172 to seal or block the valve opening 178. The spherical portion 163 may be moved, deflected, or deformed to allow flow through the connector body 172 and the valve opening 178. The spherical portion 163 may include any portion of a sphere and may define a hemisphere. In some embodiments, the valve body 162 includes a collar 168 around the spherical portion 163 to seal the valve body 162 against the connector body 172. Optionally, the spherical portion 163 may be recessed within the collar 168 against the connector body 172.

[0033] As illustrated, the valve body 162 may define a slit 166 for selectively allowing flow through the valve member 160 and the valve opening 178. In a first position, the edges of the slit 166 may come together to resist fluid flow through the valve body 162 and block the valve opening 178. In a second position, the edges of the slit 166 may be spread apart to allow flow through the valve member 160 and through the valve opening 178.

[0034] In operation, the valve members 130, 160 of the respective first and second connector portions 110, 150 can be moved, deflected, or deformed to control flow through the connector 100. As shown in FIG. 4A , when the first and second connector portions 110, 150 are separated or decoupled, the valve members 130, 160 can resist fluid flow through the valve openings 148, 178. As illustrated in FIG. 4B , when the first and second connector portions 110, 150 are engaged or coupled together, the valve members 130, 160 can contact each other and move, deflect, or deform to allow fluid flow through the valve openings 148, 178 and through the connector 100 as a whole. As illustrated, in some embodiments, deformation of the valve bodies 132, 162 can cause the respective slits 136, 166 to spread apart, allowing flow through the valve members 130, 160 and the valve openings 148, 178.

Unless otherwise noted, similar features of the fluid connector 200 are identified using similar reference numerals as those utilized with respect to the fluid connector 100. In the illustrated example, the fluid connector 200 may include valve openings 248, 278 configured to expose a larger portion of the valve members 230, 260.

[0036] In the illustrated example, connector body 242 of connector housing 240 defines a valve opening 248 at the end of connector body 242. Valve opening 248 may be defined by a wall of connector body 242 and disposed opposite luer end 243 of connector housing 240. As illustrated, valve opening 248 is in fluid communication with the housing interior space and lumen 226 of luer portion 220. In some embodiments, ridge 246 of housing body 242 is circumferentially disposed around valve opening 248.

[0037] As illustrated, the bulbous portion 233 of the valve member 230 may extend entirely beyond the valve opening 248 and the connector body 242. Additionally, as illustrated, the valve body 232 may selectively seal, restrict, or otherwise block flow through the valve opening 248, while the slit 236 may resist or allow flow through the valve body 232 without engaging or sealing against the valve opening 248.

[0038] Similarly, connector body 272 of connector housing 270 defines a valve opening 278 at an end of connector body 272. Valve opening 278 may be defined by a wall of connector body 272 and disposed opposite tubing end 273 of connector housing 270. As illustrated, valve opening 278 is in fluid communication with the housing interior space. In some embodiments, groove 276 in housing body 272 is circumferentially disposed within valve opening 278.

[0039] As illustrated, the bulbous portion 263 of the valve member 260 may be entirely recessed beyond the valve opening 278 and the edge of the connector body 272. Additionally, as illustrated, the valve body 262 may selectively seal, restrict, or otherwise block flow through the valve opening 278, while the slit 266 may resist or allow flow through the valve body 262 without engaging or sealing against the valve opening 278. In some embodiments, the collar 268 of the valve member 260 may provide a sealing surface.

FIG. 15 is an exploded perspective view of the first connector portion 310 of the fluid connector 300 of FIG. 12 according to an embodiment of the present disclosure. FIG. 16 is an exploded perspective view of the second connector portion 350 of the fluid connector 300 of FIG. 12 according to an embodiment of the present disclosure. With reference to FIGS. 12-16, the fluid connector 300 includes certain features that are similar to the fluid connector 100. Unless otherwise noted, like features of the fluid connector 300 are identified using similar reference numerals as those utilized with respect to the fluid connector 100. In the illustrated example, the fluid connector 300 may include valve members 330, 360 that are recessed relative to the connector housings 340, 370 to prevent contact or contamination of the valve members 330, 360 in the disconnected state.

[0041] In the illustrated example, first connector part 310 includes a valve member 330 embedded within a housing interior space defined by connector body 342. As illustrated, valve member 330 is recessed from valve opening 348 to prevent contact or contamination of valve member 330 when first connector part 310 is separated from second connector part 350. In some embodiments, the walls of connector body 342 define a collar that spaces valve member 330 from the leading edge of valve opening 348.

[0042] In some embodiments, the valve body 332 may define a half or hemispherical portion 333 for selectively restricting or otherwise blocking flow through the valve opening 348. The hemispherical portion 333 may be moved, deflected, or deformed to allow flow through the connector body 342 and the valve opening 348. Additionally, as illustrated, the valve body 332 may selectively restrict or otherwise block flow through the valve opening 348, while the slit 336 may resist or allow flow through the valve body 332 without engaging or sealing against the valve opening 348.

[0043] Similarly, the valve body 362 may define a half or hemispherical portion 363 for selectively restricting or otherwise blocking flow through the valve opening 378.

FIG. 20 is an exploded perspective view of the first connector portion 410 of the fluid connector 400 of FIG. 17 according to an embodiment of the present disclosure. FIG. 21 is an exploded perspective view of the second connector portion 450 of the fluid connector 400 of FIG. 17 according to an embodiment of the present disclosure. With reference to FIGS. 17-21, the fluid connector 400 includes certain features that are similar to the fluid connector 100. Unless otherwise noted, similar features of the fluid connector 400 are identified using similar reference numerals as those utilized with respect to the fluid connector 100. In the illustrated example, the fluid connector 400 can utilize spherical valve members 430, 460 to control flow through the first connector portion 410 and the second connector portion 450, respectively.

[0047] 17-21 , first connector portion 410 and second connector portion 450 each include a valve member 430, 460, respectively, to control flow through connector 400. In particular, valve members 430, 460 allow fluid to flow between first connector portion 410 and second connector portion 450 when first connector portion 410 and second connector portion 450 are connected, and prevent fluid flow when first connector portion 410 and second connector portion 450 are disconnected. In some embodiments, second connector portion 450 includes an O-ring 479 to enable sealing between first connector portion 410 and second connector portion 450.

[0048] In the illustrated example, the first connector portion 410 includes a valve member 430 disposed within a housing interior space defined by a connector body 442. As illustrated, the valve body 432 can selectively restrict or block flow through the connector body 442 and / or a valve opening 448. In operation, the valve body 432 can be moved or deflected to allow flow through the connector body 442 and the valve opening 448. As illustrated, the valve body 432 can define a sphere or ball 133 for selectively sealing, restricting, or otherwise blocking flow through the valve opening 448. In a first position, the valve body 432 can engage and block the valve opening 448. In a second position, the valve body 432 can be spaced from the valve opening and allow flow through the valve opening 448. The valve body 432 can be formed from a rigid material.

[0049] As illustrated, the valve body 432 can be biased toward the valve opening 448 to control the flow through the valve opening 448. In the illustrated example, the valve housing 480 can bias the valve body 432 toward the valve opening 448. As illustrated, the valve housing 480 can receive the valve body 432 in a cup 484. The valve housing 482 and the cup 484 can bias the valve body 432 toward the valve opening 448. In operation, the valve housing 480 can be deformed or energized as the valve body 432 is displaced away from the valve opening 448. In some embodiments, the valve housing body 482 can be disposed within the housing interior space of the connector housing 440. In some cases, the valve housing body 482 can include a flow channel to allow fluid flow through the valve housing 480.

[0050] Similarly, the second connector portion 450 includes a valve member 460 disposed within a housing interior space defined by a connector body 472. As illustrated, the valve body 462 can selectively restrict or block flow through the connector body 472 and / or a valve opening 478. In operation, the valve body 462 can be moved or deflected to allow flow through the connector body 472 and the valve opening 478. As illustrated, the valve body 462 can define a sphere or ball for selectively sealing, restricting, or otherwise blocking flow through the valve opening 478. In a first position, the valve body 462 can engage and block the valve opening 478. In a second position, the valve body 462 can be spaced from the valve opening and allow flow through the valve opening 478. The valve body 472 can be formed from a rigid material.

[0051] As illustrated, the valve body 462 can be biased toward the valve opening 478 to control the flow through the valve opening 478. In the illustrated example, a valve housing 490 can bias the valve body 462 toward the valve opening 478. As illustrated, the valve housing 490 can receive the valve body 462 in a cup 494. The valve housing 492 and cup 494 can bias the valve body 462 toward the valve opening 478. In operation, the valve housing 490 can be deformed or energized as the valve body 462 is displaced away from the valve opening 478. In some embodiments, the valve housing body 492 can be disposed within the housing interior space of the connector housing 470. Optionally, the valve housing body 492 can include a flow channel to allow fluid flow through the valve housing 490.

[0052] In operation, the valve members 430, 460 of the respective first and second connector portions 410, 450 can be moved or deflected to control flow through the connector 400. As illustrated in FIG. 19A , when the first and second connector portions 410, 450 are separated or disconnected, the valve housings 480, 490 bias the valve members 430, 460 toward the valve openings 448, 478 to resist fluid flow through the valve openings 448, 478. As illustrated in FIG. 19B , when the first and second connector portions 410, 450 are engaged or coupled together, the valve members 430, 460 can contact each other and move or deflect to allow fluid flow through the valve openings 448, 478 and through the connector 400 as a whole. As illustrated, in some embodiments, the valve housings 480, 490 may deform to allow the valve members 430, 460 to deflect or displace, allowing fluid flow through the valve openings 448, 478.

[0053] FIG. 22 illustrates a perspective view of a fluid connector 500 according to an embodiment of the present disclosure. FIG. 23 illustrates a cross-sectional view of the separated fluid connector 500 of FIG. 22 according to an embodiment of the present disclosure. FIG. 24 illustrates a cross-sectional view of the connected fluid connector 500 of FIG. 24 according to an embodiment of the present disclosure. With reference to FIGS. 22-24, the fluid connector 500 provides a "fusible link" and can utilize a flange 540 and spherical valve members 530, 570 to control flow through the first connector portion 510 and the second connector portion 550, respectively.

[0054] In the illustrated example, the fluid connector 500 provides a flow path or fluid pathway from a first end 514 to a second end 554 of the fluid connector 500. As illustrated, the fluid connector 500 includes a first connector portion 510 and a second connector portion 550 coupled together to form the fluid pathway.

[0055] In the illustrated example, first connector portion 510 allows fluid flow to or from a patient or any other portion of an IV set. In the illustrated example, first connector portion 510 includes a luer portion 520 to allow first connector portion 510 to be connected to a luer connector or any other suitable connector. As illustrated, a mating connector can be attached to first end 514. Fluid can pass to and from fluid connector 500 through the mating connector via a lumen defined in luer portion 520. In the illustrated example, luer portion 520 can be coupled to connector housing 516 of first connector portion 510.

[0056] As illustrated, second connector portion 550 allows for fluid flow to or from a fluid source or any other portion of an IV set. In the illustrated example, second connector portion 550 includes a tubing portion 560 that allows second connector portion 550 to be connected to a fluid source or other portion of an IV set. Tubing or a connector may be received in or attached to second end 554 of tubing portion 560.

[0057] As illustrated, connector housing 516 of first connector portion 510 and connector housing 556 of second connector housing 550 can be coupled together to allow flow between first connector portion 510 and second connector portion 550. In the illustrated example, connector housing 516 can define channels 534, 536 that are in fluid communication with the lumen of luer portion 520. Similarly, connector housing 556 can define channels 574, 576 that are in fluid communication with the lumen of tubing portion 560. As illustrated in FIG. 23B , when first connector portion 510 and second connector portion 550 are coupled together, fluid can flow between channel 536 of first connector portion 510 and channel 576 of second connector portion 550, allowing flow between first connector portion 510 and second connector portion 550.

[0058] In the illustrated example, first connector portion 510 and second connector portion 550 may be engaged to secure or hold first connector portion 510 and second connector portion 550 together. As illustrated, first connector portion 510 and second connector portion 550 may be coupled together by inserting a portion of second connector portion 550 into first connector portion 510. In the illustrated example, connector housing 556 of second connector portion 550 includes or defines a ridge 562. As illustrated, ridge 562 extends radially outward from connector housing 556. Similarly, connector housing 516 of first connector portion 510 defines a lip 522. In operation, the ridge 562 of the second connector portion 550 can engage the lip 522 of the first connector portion 510 to couple the first connector portion 510 and the second connector portion 550 together.

[0059] In the illustrated example, lip 522 and the circumferential wall of connector housing 516 engage ridge 562 of second connector portion 550 to resist movement of first connector portion 510 and second connector portion 550 away from each other. The engagement of lip 522 with ridge 562 may define a snap fit or snap joint between first connector portion 510 and second connector portion 550 in some instances of the present disclosure.

[0060] The lip 522 is configured to resist separation between the first connector portion 510 and the second connector portion 550, but the lip 522 and / or the ridge 562 are also configured to allow separation between the first connector portion 510 and the second connector portion 550 when a force exceeding a threshold force is applied between the first connector portion 510 and the second connector portion 550. In some embodiments of the present disclosure, the threshold force for separation between the first connector portion 510 and the second connector portion 550 is approximately 2.27 kg (5 pounds) (22.25 Newtons) or greater. Separation between the first connector portion 510 and the second connector portion 550 can occur when the lip 522 and / or the circumferential wall of the connector housing 516 is biased or deflected away from the ridge 562. In the illustrated example, the first connector portion 510 and the second connector portion 550 can be separated from one another while maintaining the ability to reconnect the first connector portion 510 and the second connector portion 550 together. In some embodiments, the resistance or force to assembly and separation between the first connector portion 510 and the second connector portion 550 can be configured such that the force required to assemble the first connector portion 510 and the second connector portion 550 is less than the force required to separate the first connector portion 510 and the second connector portion 550.

[0061] In the illustrated example, the first connector portion 510 and the second connector portion 550 each include a valve member 530, 570, respectively, for controlling flow through the connector 500. In particular, the valve members 530, 570 allow fluid to flow between the first connector portion 510 and the second connector portion 550 when the first connector portion 510 and the second connector portion 550 are connected, and prevent fluid flow when the first connector portion 510 and the second connector portion 550 are disconnected.

[0062] In the illustrated example, the first connector portion 510 includes a valve member 530 disposed within an interior housing space defined by a connector housing 516. As illustrated, the valve member 530 can selectively restrict or block flow through the connector housing 516 and / or a channel 536. In operation, the valve member 530 can be moved or deflected to allow flow through the connector housing 516 and the channel 536. As illustrated, the valve member 530 can define a sphere or ball for selectively sealing, restricting, or otherwise blocking flow through the channel 536. In a first position, the valve member 530 can engage and block the channel 536. In a second position, the valve member 530 can be spaced from the valve opening and allow flow through the channel 536. The valve member 530 can be formed from a rigid material.

[0063] As illustrated, valve member 530 can be biased toward channel 536 to control flow through channel 536. In the illustrated example, biasing member 532 can bias valve member 530 toward channel 536. In some embodiments, biasing member 532 can be a spring or any other suitable biasing member. In operation, biasing member 532 can be deformed or energized as valve member 530 is displaced away from channel 536. In some embodiments, biasing member 532 can be disposed within an interior housing space of connector housing 516.

[0064] Similarly, the second connector portion 550 includes a valve member 570 disposed within the housing interior space defined by the connector housing 556. As illustrated, the valve member 570 can selectively restrict or block flow through the connector housing 556 and / or the channel 576. In operation, the valve member 570 can be moved or deflected to allow flow through the connector housing 556 and the channel 576. As illustrated, the valve member 570 can define a sphere or ball for selectively sealing, restricting, or otherwise blocking flow through the channel 576. In a first position, the valve member 570 can engage and block the channel 576. In a second position, the valve member 570 can be spaced from the valve opening and allow flow through the channel 576. The valve member 570 can be formed from a rigid material.

[0065] As illustrated, valve member 570 can be biased toward channel 576 to control flow through channel 576. In the illustrated example, biasing member 572 can bias valve member 570 toward channel 576. In some embodiments, biasing member 572 can be a spring or any other suitable biasing member. In operation, biasing member 572 can be deformed or energized as valve member 570 is displaced away from channel 576. In some embodiments, biasing member 572 can be disposed within an interior housing space of connector housing 556.

[0066] In operation, the valve members 530, 570 of the respective first and second connector portions 510, 550 can be moved or deflected to control flow through the connector 500. As illustrated in FIG. 23A , when the first and second connector portions 510, 550 are separated or decoupled, the biasing members 532, 572 bias the valve members 530, 570 toward the channels 536, 576 to resist fluid flow through the channels 536, 576. As illustrated in FIG. 23B , when the first and second connector portions 510, 550 are engaged or coupled together, the valve members 530, 570 can be moved or deflected to allow fluid flow through the channels 536, 576 and through the connector 500 as a whole. As illustrated, in some embodiments, the biasing members 532, 572 can compress to allow the valve members 530, 570 to deflect or displace, allowing fluid flow through the channels 536, 576.

[0067] In the illustrated example, first connector portion 510 includes flange 540 to facilitate fluid transfer between first connector portion 510 and second connector portion 550. As illustrated, when first connector portion 510 and second connector portion 550 are connected, flange 540 can displace valve members 530, 570 and direct fluid flow between channels 536, 576. In the illustrated example, flange 540 includes protrusions 542, 544 for engaging or displacing valve members 530, 570, respectively. In some embodiments, flange 540 further defines channels 543, 546, 545 to allow fluid flow through or across flange 540. As illustrated, channel 543 can be formed in protrusion 542, channel 546 can be formed in the main body of flange 540, and channel 545 can be formed in protrusion 544. In some applications, channel 543 is configured to selectively fluidly contact channel 536 when valve member 530 is displaced by protrusion 542, and channel 545 is configured to selectively fluidly contact channel 576 when valve member 570 is displaced by protrusion 544.

[0068] 23A, when the first and second connector portions 510, 550 are separated or disconnected, the flange biasing member 541 can urge the flange 540 and protrusions 542 away from the valve member 530, preventing or resisting flow across the flange 540. As illustrated in FIG. 23B, when the first and second connector portions 510, 550 are engaged or coupled together, the protrusions 542, 544 of the flange 540 can move or deflect the valve members 530, 570 to allow fluid flow from the channels 536, 576 through the channels 543, 546, 545 of the flange 540, allowing flow through the connector 500 overall.

[0098] Various items may be arranged differently (e.g., placed in a different order or divided in a different manner) without departing from the scope of the subject technology. All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later become known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Furthermore, nothing disclosed herein is intended to be made available to the public, regardless of whether such disclosure is expressly recited in the claims. No claim element is to be construed under the provisions of 35 U.S.C. § 112, paragraph 6, unless the element is expressly recited using the phrase "means for," or, in the case of a method claim, unless the element is recited using the phrase "step for." Still further, with respect to the use of the terms "comprises," "having," and the like, such terms are intended to be as inclusive as "comprising," as the term "comprising" would be interpreted when used as a transitional phrase in a claim.

[0099] The Title, Background, Summary, Brief Description of the Drawings, and Abstract of this disclosure are hereby incorporated into this disclosure and are provided as illustrative examples of the disclosure, not as a limiting description. This disclosure is submitted with the understanding that they will not be used to limit the scope or meaning of the claims. Additionally, in the Detailed Description, it may be recognized that the description provides exemplary illustrations, and that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed structure or operation. The following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as separately claimed subject matter.

[0100] The claims are not intended to be limited to the embodiments described herein, but are to be accorded the full scope consistent with the claims as written and to encompass all legal equivalents. Nevertheless, no claim is intended to, and should not be construed to, encompass subject matter that does not satisfy the requirements of 35 U.S.C. §§ 101, 102, or 103.
