Description
- This application is a continuation of U.S. application Ser. No. 16/984,315, filed Aug. 4, 2020, and is a continuation of U.S. application Ser. No. 16/149,391, filed Oct. 2, 2018, now U.S. Pat. No. 10,864,364, issued Dec. 15, 2020, and claims the benefit of U.S. Application Ser. No. 62/570,733, filed Oct. 11, 2017, the entirety of which is incorporated herein by reference.
- The present technology is generally related a dry disconnect device for transferring blood between a patient and an external device.
- Extracorporeal medical procedures include transferring blood outside of a patient's body using one or more fluid transfer tubes, such as catheters, connected to the patient and a machine to establish a continuous fluid pathway therebetween. For example, extracorporeal membrane oxygenation (“ECMO”) machines pump and oxygenate the patient's blood from outside of the patient's body and thereafter return the oxygenated blood to the patient's body. The tubes and/or the machine must be carefully connected to each other as the introduction of air bubbles into the fluid pathway increases the risk of death or medical complications, such as thrombus.
- Various systems and devices have been developed to connect fluid transfer tubes to each other. However, such systems and devices are complicated to use, consume a relatively large amount of space, and are of a size and shape prone to creating thrombus. Existing devices, such as dry disconnect couplings, are configured to connect and disconnect the fluid transfer tubes, however, such devices are susceptible to leakage and creating hazardous air bubbles. Still, other devices don't allow for connecting and disconnecting the fluid transfer tubes following a first initial connection. As a further drawback, known systems and devices are not equipped with various safety features, such as a safety lock and/or status indicator, to indicate the status of fluid transfer.
- The techniques of this disclosure generally relate to a dry disconnect device configured to transfer blood from a patient to an external device without introducing air bubbles into the device.
- In one aspect, the present disclosure provides a dry disconnect device including a first housing and a second housing lockingly engageable with each other and defining a fluid pathway therebetween; a female valve disposed within the first housing and having an extended position including the female valve sealing the fluid pathway and a retracted position including the female valve outside of the fluid pathway; a male valve disposed within the second housing and having an extended position including the male valve outside of the fluid pathway and a retracted position when the female valve is in the extended position, the retracted position including the male valve sealing the fluid pathway; and a male valve transition member in communication with the male valve for transitioning the male valve from the retracted position to the extended position when the first housing is locked to the second housing, the extended position of the male valve causing the female valve to transition from the extended position to the retracted position and causing the fluid pathway between the first housing and the second housing to be in fluid communication.
- In another aspect, the disclosure provides the first housing defining an outlet and an outlet portion of the fluid pathway, and the female valve seals the outlet portion of the fluid pathway when the female valve is in the extend position.
- In another aspect, the disclosure provides the second housing defining an inlet and an inlet portion of the fluid pathway, and the male valve includes a proximal portion and a distal portion opposite the proximal portion, the proximal portion translating from the second housing into the first housing when the male valve is in the extended position.

- In another aspect, the disclosure provides the dry disconnect device including a gasket surrounding the proximal portion of the male valve.
- In another aspect, the disclosure provides the male valve transition member being a biasing member coupled to the distal portion of the male valve, and the second housing includes a rotatable fastener coupled to the male valve transition member.
- In another aspect, the disclosure provides the dry disconnect device including a female valve transition member coupled to the female valve.

- Referring now to the drawings in which like reference designators refer to like elements there is shown in
FIG. 1 an exemplary dry disconnect device constructed in accordance with the principles of the present application and designated generally “10.” Thedry disconnect device 10 is configured to lock and transfer blood from a patient to an external device without the risk of air bubbles entering thedevice 10.FIG. 1 depicts thedevice 10 including afirst housing 12 defining anoutlet 14 and asecond housing 16 defining aninlet 18 for fluid to travel from theinlet 18 to theoutlet 14. Thesecond housing 16 is lockingly engageable with thefirst housing 12.FIG. 1 depicts thehousings FIGS. 2 and 3 depict thehousings first housing 12 and thesecond housing 16 include an interior made of biocompatible materials, such as stainless steel, titanium, composite, ceramic, silicone, or the like with thesecond housing 16 being configured to connect to a patient for an extended time period, such as weeks, months, or years. -
FIG. 4 is a cross-sectional side view of thedevice 10 taken along section A-A ofFIG. 3 . Thefirst housing 12 defines anoutlet portion 20 of afluid pathway 22 in fluid communication with theoutlet 14 and extending through thefirst housing 12. A first valve orfemale valve 24 is disposed within thefirst housing 12 to selectively seal theoutlet portion 20 of thefluid pathway 22, which may also be referred to as a channel. Thesecond housing 16 defines aninlet portion 26 of thefluid pathway 22 in communication with theinlet 18 and extending through thesecond housing 16. As such, theinlet portion 26 and theoutlet portion 20 collectively define thefluid pathway 22 through thedevice 10 to transfer blood from the patient to an external device (not shown). A second valve ormale valve 28 is disposed within thesecond housing 16 for selectively sealing theinlet portion 26 of thefluid pathway 22. - The
female valve 24 and themale valve 28 selectively seal thefluid pathway 22 by moving in and out of thefluid pathway 22. For example,FIG. 4 depicts thefemale valve 24 including an extended or closed position in which thefemale valve 24 extends away from arear wall 30 and within thefluid pathway 22 to seal theoutlet portion 20. Themale valve 28 is depicted in a retracted or closed position within thesecond housing 16 and uncoupled from thefemale valve 24 to seal theinlet portion 26 of thefluid pathway 22. -
FIG. 5 depicts the opposite configurations with respect toFIG. 4 , namely thefemale valve 24 including a retracted or open position in which thefemale valve 24 retracts within thefirst housing 12 toward therear wall 30 and outside of thefluid pathway 22. In addition, themale valve 28 is in the extended position in which themale valve 28 extends into thefirst housing 12 to contact thefemale valve 24 and transition thefemale valve 24 from the closed position to the open position. In other words, themale valve 28 forces thefemale valve 24 toward therear wall 30 of thefirst housing 12 to move thefemale valve 24 and themale valve 28 outside of thefluid pathway 22. Once thefemale valve 24 is retracted outside of thefluid pathway 22, theoutlet portion 20 and theinlet portion 26 of thefluid pathway 22 are open and caused to be in fluid communication with each other. -
FIGS. 4 and 5 depict themale valve 28 including aproximal portion 32 and adistal portion 34 opposite theproximal portion 32 with theproximal portion 32 being that which is inserted within thefirst housing 12. Theproximal portion 32 may be circular or another shape that is complimentary to a shape of aproximal portion 36 of thefemale valve 24. As such, theproximal portion 32 of themale valve 28 and theproximal portion 36 of thefemale valve 24 may be pressed together to form a fluid and/or air tight seal therebetween. The shape of themale valve 28 is also sized to seal thefluid pathway 22 and an aperture 38 (FIG. 5 ) defined by thesecond housing 16 which allows fluid to flow outside of thesecond housing 16 into thefirst housing 12 when thedevice 10 is activated.FIG. 2 depicts agasket 40 surrounding theproximal portion 32 of themale valve 28 to further prevent leakage of fluid between themale valve 28 and thesecond housing 16 when themale valve 28 is in the closed position. Thefirst housing 12 defines anaperture 42 which aligns with theaperture 38 to allow fluid to flow from thesecond housing 16 into thefirst housing 12. - In one configuration, safety of the
device 10 is increased through themale valve 28 being placed in the extended position after confirming that thefirst housing 12 is coupled to thesecond housing 16 to from a fluid tight seal therebetween. For example,FIG. 5 depicts thedevice 10 in use including anoutlet tube 44 disposed within theoutlet 14 and aninlet tube 46 disposed within theinlet 18. Theoutlet tube 44 may extend to an external device with theinlet tube 46 being coupled to the patient. Blood may be transferred from the patient through thedevice 10 to the external device without the risk of air bubbles entering thefluid pathway 22 as theentire device 10 is sealed with the only openings being theinlet 18 and theoutlet 14. In other words, blood travels through thedevice 10 from theinlet 18 to theoutlet 14 without exposure to air. -
FIGS. 4 and 5 depict thedevice 10 including a malevalve transition member 48 coupled to thedistal portion 34 of themale valve 28 to transition themale valve 28 from the closed position to the open position. In one configuration, the malevalve transition member 48 is a biasing member, such as a spring, coupled to arotatable fastener 50, such as a hex nut, screw, or the like. Rotation of therotatable fastener 50 moves the malevalve transition member 48 to bias themale valve 28 proximally toward thefirst housing 12. In the alternative, the malevalve transition member 48 may be a solenoid or another electromagnet allowing for electrical operation and manipulation of themale valve 28. Such examples are not intended to be limiting. - In one configuration, a female
valve transition member 52, such as a spring, may be coupled to adistal end 54 of thefemale valve 24. In use, themale valve 28 pushing against thefemale valve 24 causes thefemale valve 24 to retract against the femalevalve transition member 52 to counter the force of the malevalve transition member 48. The counter force maintains the fluid and/or air tight seal between thefemale valve 24 and themale valve 28. In other configurations, the femalevalve transition member 52 may be another mechanical or a magnetic component configured to counter the force of the malevalve transition member 48. -
FIGS. 5 and 6 depict thefirst housing 12 including ashoulder 56 for receiving thefemale valve 24 in contact therewith. For example,FIG. 5 depicts thefemale valve 24 in the open position including thefemale valve 24 resting firmly on theshoulder 56. Theshoulder 56 may include a smoothouter surface 58 to promote blood flow through thefluid pathway 22 and decrease the risk of thrombus or blood becoming stagnate within thefluid pathway 22. -
FIG. 7 depicts a transparent perspective view of thedevice 10 including thefluid pathway 22 being continuous and uninterrupted when theoutlet portion 20 and theinlet portion 26 are in fluid communication with each other. The continuous anduninterrupted fluid pathway 22 promotes blood flow and decreases the risk of thrombus within thedevice 10. In other words, fluid, such as blood, flows freely through thefluid pathway 22 without obstructions and/or turbulence. For example,FIG. 7 depicts thedevice 10 including thefemale valve 24 disposed within acylindrical housing member 60. Thecylindrical housing member 60 is free of protrusions and creates a barrier between thefemale valve 24 and blood flowing through thedevice 10 during transfer. The remaining portions of thedevice 10 which define thefluid pathway 22 are also free of protrusions, sharp edges, and the like, known to cause thrombus, shear stress, or other types of blood damage. In configurations not including thecylindrical housing member 60, the smoothouter surface 58 of theshoulder 56 also reduces the risk of thrombus and/or other types of blood damage. - The
device 10 defines adevice axis 62 extending through thefirst housing 12 and thesecond housing 16. Theinlet 18 and theoutlet 14 are depicted as being transverse to thedevice axis 62 with thefluid flow pathway 22 being through theinlet 18 and subsequently parallel to thedevice axis 62 to thefirst housing 12 where the fluid may flow in a circumferential direction around thefemale valve 24 to theoutlet 14. - The
device 10 includes a lockingmember 64 which locks thefirst housing 12 and thesecond housing 16 together during use of thedevice 10. The lockingmember 64 may be coupled to either or bothhousings member 64 includes abase 66 and amoveable member 68, such as a pin, lever, handle, or the like, inserted within thebase 66 through manual, device, or system activation, such as using an electrical solenoid. - A local or
remote position sensor 70 is proximate the lockingmember 64 and may be coupled to either or bothhousings position sensor 70 may be an accelerometer, resistance-based sensor, capacitive sensor, optical sensor, or the like, in communication with either or bothvalves valves fluid pathway 22. Such information indicates the status of the mechanical state of operation, such as whether thefluid pathway 22 is obstructed or open. Theremote position sensor 70 may communicate the measurement or position information associated with thefirst valve 24 and/or thesecond valve 28 visually through a display, audibly through a speaker, or the like through thedevice 10. In the alternative, such information may be transmitted to aremote device 10 having a processor in communication with thedevice 10 through a wired or wireless link. Thefluid pathway 22 being open indicates that thedevice 10 should remain locked and it is safe to transfer fluid through thedevice 10. For example, with respect toFIG. 7 , theposition sensor 70 is configured to detect that thefirst housing 12 and thesecond housing 16 are lockingly engaged with respect to each other, themale valve 28 is coupled to thefemale valve 24, and theoutlet portion 20 and theinlet portion 26 of thefluid pathway 22 are in communication with each other. As such, theopen fluid pathway 22 indicates that it is safe to transfer fluid through thedevice 10 without the risk of air bubbles entering the device or leakage of fluid. -
FIG. 8 is a cross-sectional side view of another embodiment of adry disconnect device 72 including afirst housing 74 and asecond housing 76 defining adevice axis 78 and afluid pathway 80 extending therethrough. Thefirst housing 74 defines an outlet 82 and thesecond housing 76 defines aninlet 84 for thefluid pathway 80. The outlet 82 and theinlet 84 are positioned parallel to thedevice axis 78. In addition, a portion of thefluid pathway 80 is parallel to thedevice axis 78 with the exception of a curved or angled portion around afemale valve 86 and amale valve 88. Thedry disconnect device 72 operates in a manner the same as or similar to thedry disconnect device 10 with the outlet 82, theinlet 84, and thefluid pathway 80 being in different locations with respect to thedevice 10. - It should be understood that various aspects disclosed herein may be combined in different combinations than the combinations specifically presented in the description and accompanying drawings.
