Abstract
A new valve for regulating the flow of liquid has two housings that are removably attached to one another. When the housings are separated, the liquid can no longer pass through the valve. A system of magnetic elements is used to cycle the flow of liquid (urine) through the valve. The valve is typically connected to an indwelling bladder catheter and the valve allows the patient to be at least temporarily disconnected from a collection bag.
Description
- This application is a continuation application of and claims priority to U.S. patent application Ser. No. 13/105,640, filed on May 5, 2011, which is hereby incorporated by reference in its entirety.
- A new design for a valve that regulates the flow of a liquid has the ability to passively regulate the flow of liquid and allows the valve housing to be disconnected, allowing movement of the person to whom the valve is connected away from a collection bag.
- Many people, at home, in a hospital, and in third-party care facilities require the use of an in-dwelling bladder catheter because of a medical condition. However, being constantly attached to a bladder bag that holds the liquid (urine) is inconvenient and potentially and unnecessarily limits the person's movement and living conditions.
- A new valve allows for the cyclical emptying of the bladder and allows the patient to be disconnected from the collection bag.
- The present invention is directed to a valve for regulating the flow of a liquid therethrough that includes a first housing having an inlet and an outlet, a second housing removably attachable to the first housing, the second housing having an opening extending therethrough, a first magnet disposed in the first housing in a predetermined position, the first magnet being stationary relative to the housing, a second magnet disposed in the first first housing, the second magnet movable relative to the first magnet, and a sealing member disposed in the first housing adjacent the outlet, the sealing member sealing the outlet in the first housing when the second housing is disengaged from the first housing.
- In some embodiments, the valve includes a resealable opening disposed in the first housing.
- In some embodiments, the valve includes a vent disposed in the second housing.
- In some embodiments, the sealing member includes an elastic member that engages a portion of the first housing and the second housing has a projection that engages the sealing member and compresses the elastic member when the second housing engages the first housing.
- In another aspect, the invention is directed to a removable housing to engage a housing with at least one closable opening therein, the removable housing includes an outer housing having first end to engage the housing with at least one closable opening and a second end to engage tubing, an opening extending between the first end and the second end of the outer housing, a latch disposed adjacent the first end to engage at least a portion of the housing with at least one closable opening to maintain the removable housing in contact with the housing with at least one closable opening, a projection disposed at least partially within the opening, the projection extending from a middle portion of the opening toward the first end and configured to be disposed within an opening of the housing with at least one closable opening.
- In yet another aspect, the invention is directed to a valve for regulating the flow of a liquid therethrough that includes a first housing having an inlet and an outlet, the inlet and outlet being in fluid communication with one another, a second housing removably attachable to the first housing, the second housing having an opening extending therethrough and in fluid communication with the outlet when the second housing is connected to the first housing, and a sealing member disposed in the first housing adjacent the outlet, the sealing member sealing the outlet in the first housing when the second housing is disengaged from the first housing.
- Additional features and advantages of the invention will be set forth in the detailed description which follows, and in part will be readily apparent to those skilled in the art from that description or recognized by practicing the invention as described herein, including the detailed description which follows, the claims, as well as the appended drawings.

Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.
- One embodiment of the present invention illustrated in the figures is directed is a
valve 10 for regulating the flow of a liquid. Thevalve 10 has afirst housing 12 and asecond housing 14 that is removably attachable to thefirst housing 12. Thefirst housing 12 has acatheter connector 16 having aproximal end 18 and adistal end 20, theproximal end 18 of thecatheter connector 16 has aninlet 22 that is configured to engage a tubing (see, e.g.,FIG. 10 ). Theinlet 22, as illustrated, has a generally smooth outer surface that increases in diameter from the end of theinlet 22 toward the remaining portion of thecatheter connector 16. Theinlet 22 may have any other configuration that allows for connection to tubing and still fall within the scope of the present invention. The first andsecond housings - As best illustrated in
FIG. 4 , thecatheter connector 16 also has anopening 24 that functions as a sampling port. The opening 24 preferably has aneedleless port 26. Theneedleless port 26 allows for insertion of a needleless syringe (not shown) to withdraw a sample of the liquid (generally urine) for testing. Theneedleless port 26 is preferably a resealable opening. Theneedleless port 26 has amain body 28 and theresealable portion 30, theresealable portion 30 may or may not have a pre-cut slit therein. It is also possible that theneedleless port 26 is a single unit and not made of two different portions. Themain body 28 is preferably made of polypropylene and theresealable portion 30 is preferably made of a thermoplastic elastomer, but any appropriate materials may be used. - The
catheter connector 16 also has an opening 40 at thedistal end 20 that is in fluid communication with theinlet 22. The opening 40 has arecessed portion 40 a adjacent thedistal end 20 into which afirst magnet housing 42 is disposed, sealing the opening 40 of thecatheter connector 16. See, e.g.,FIGS. 6-9 . Thefirst magnet housing 42 has abase plate 44 that has the same configuration as the opening 40 and anopening 46 in thebase plate 44 to allow the liquid to pass therethrough. On afirst side 48 of the base plate 44 afirst magnet 50 is secured. Thefirst magnet 50 is secured inextensions 52 that extend from thefirst side 48 of thebase plate 44 to keep thefirst magnet 50 at a predetermined distance from theopening 46 and a second magnet, which is described in more detail below. The first magnet housing 42 preferably has on a second side 54 a raisedportion 56 around the opening 46. As described in more detail below, the raised portion provides a surface against which the second magnet can maintain contact to seal theopening 46. - As best illustrated in FIGS. 4 and 6-9,
second magnet housing 60, also a part of thefirst housing 12, is attached to thefirst magnet housing 40 and thecatheter connector 16 and extends distally from thecatheter connector 16. Thesecond magnet housing 60 is preferably generally cup-shaped, having abase member 62 and aperipheral wall 64, with an opening 66 in thebase member 62 to allow the liquid to flow therethrough. Extending from thebase member 62 toward thecatheter connector 16 and thefirst magnet housing 42 areextensions 68 that slidingly hold a thesecond magnet 70. Preferably, there are fourextensions 68, but there may be other numbers of extensions and still be within the scope of the invention. Theextensions 68 also have asurface 72 to engage thesecond magnet 70 and prevent thesecond magnet 70 from moving too far distally (toward the base member 62). Thesecond magnet 70 is drawn magnetically toward thefirst magnet 50 causing thesecond magnet 70 to engage the raisedportion 56 around theopening 46, thereby closing theopening 46 and preventing the flow of liquid through thevalve 10. However, when sufficient liquid is present in theopening 40 and exerts pressure on thesecond magnet 70 sufficient to overcome the magnetic attraction between the twomagnets second magnet 70 moves axially away from theopening 46 within the extensions 68 (but no farther than the surfaces 72) to allow the liquid to drain through the opening 46 (and the tubing that is inserted into bladder of a patient). When the liquid has drained away and removes this force, then the magnetic attraction causes thesecond magnet 70 to once again close theopening 46. - The
second magnet housing 60 has on a bottom side 80 arecessed portion 82 to receive anelastic member 84 that engages and biases a sealingmember 90 toward thesecond housing 14 in adrain end 92. While a coil spring is illustrated as theelastic member 84, any appropriate style of spring or elastic member may be used to bias the sealingmember 90. The sealingmember 90 preferably has two elements, amain sealing member 94 and aresilient cover member 96 that is attached to the main sealingmember 94. However, the sealingmember 90 may be one integral element rather than two separate elements and may be made from a single material rather than multiple materials. - The
drain end 92, which constitutes the last element of thefirst housing 12, is attached to thesecond magnet housing 60 and is in fluid communication with theinlet 22 in thecatheter connector 16. See FIGS. 4 and 6-9. Thedrain end 92 has a generallycylindrical center portion 98 in which the sealingmember 90 is slidingly movable. Thecylindrical center portion 98 has aninlet 100 and anoutlet 102. The sealingmember 90 is, as noted above, biased away from thesecond magnet housing 60 and toward theoutlet 102 of thedrain end 92. Thedrain end 92 also has anouter portion 104 that is secured to thebottom side 80 of thesecond magnet housing 60. Between thecylindrical center portion 98 and theouter portion 104 is anopening 106 into which acantilevered latch 108 from thesecond housing 14 is inserted to hold thesecond housing 14 to thefirst housing 12. - The
second housing 14 has aproximal end 110 and adistal end 112. Thesecond housing 14 has aninner opening 114 that extends between theproximal end 110 and thedistal end 112 and defines aninner surface 116. Thesecond housing 14 also has aoutside surface 118 and anopening 120 that extends between theoutside surface 118 and theinner surface 116. The opening 120 functions as a vent to allow air to enter thevalve 10 and the liquid to move through thevalve 10 and into thecollection bag 140. SeeFIG. 10 . Theopening 120 is preferably covered by a Tyvek covering 122 and acover 124, which allows air to enter into thevalve 10 for complete (or near-complete) emptying of thevalve 10 without allowing the liquid to escape therethrough. - Positioned within the
inner opening 114 is aprojection 130 that extends fromcentral portion 132 of theinner opening 114 toward theproximal end 110. Theinner opening 114 also has in the central portion 132 (and preferably at the location of the distal end 134 of the projection 130) a proximally-facingsurface 136. Theinner opening 114 is configured and sized to receive thecylindrical center portion 98 of thefirst housing 12 therein and the proximally-facingsurface 136 is positioned and configured such that the outer portions ofoutlet 102 of thedrain end 92 make contact with thesurface 136 and seal thevalve 10 to prevent leaking when the twohousings projection 130 is configured and sized, when thesecond housing 14 is connected to thefirst housing 12, to engage the sealingmember 90 through theoutlet 102 of thedrain end 92 and move it axially and in a proximate direction (toward the inlet 22). This allows for the liquid to drain from thefirst housing 12 in to thesecond housing 14. Openings spaced around the bottom of theprojection 130 allow the liquid to pass around theprojection 130 and along theinner surface 114. Since theproximal end 110 of thesecond housing 14 is, by way of thelatch 108, removably mounted to thefirst housing 12, removing thesecond housing 14 also removes theprojection 130 from thedrain end 92, allowing the sealingmember 90 to seal theoutlet 102, even if thesecond magnet 70 moves to allow the liquid to pass through theopening 46. This allows the patient to, at least temporarily, be separated from acollection bag 140, which is illustrated inFIG. 10 . - As noted above, the first and
second housings latch 108. By “removably attached,” Applicant means that the twohousings housings FIGS. 5 and 6 , thelatch 108 is integral with thebutton 138, which when pressed then causes thelatch 108 to be disengaged from theouter portion 104 of thedrain end 92, and thehousing 14 can be removed fromhousing 12. It should also be noted that due to the tight fit of thecylindrical center portion 98 in theinner opening 114, only onelatch 108 needs to be used to maintain the connection between the twohousings valve 10 and still come within the scope of the present invention. - Turning now to
FIGS. 6-10 , the operation of thevalve 10 will be described in more detail.FIG. 6 is a cross sectional view of thevalve 10 through thelatch 108. The position of thesecond magnet 70 is in the proximal position, that is thesecond magnet 70 is sealing off theopening 46 as it makes contact with the raisedportion 56 around theopening 46. As can be seen in the left side of the figure, theprojection 130 has engaged the sealingmember 90 through theoutlet 102 since thesecond housing 14 is attached to thefirst housing 12. -
FIG. 7 is a cross sectional view of thevalve 10 at a 90° angle to the view inFIG. 6 . In this figure, thesecond magnet 70 is illustrated as if the liquid has exerted a sufficient force on thesecond magnet 70 to move it away from the raisedportion 56 around theopening 46 and toward thesurfaces 72. -
FIG. 8 is a cross sectional view ofvalve 10 in the same orientation asFIG. 6 , but thesecond magnet 70 is is the open position and not closed as inFIG. 6 . Additionally, the arrow indicates at least one path for the liquid to pass through thevalve 10. -
FIG. 9 is a cross section of thevalve 10 with thefirst housing 12 and thesecond housing 14 separated from one another. In this figure, it is clear that theprojection 130 no longer engages the sealingmember 90, and the sealingmember 90 is firmly in theoutlet 102, preventing the liquid from exiting thefirst housing 12. This configuration allows a patient to disconnect thehousings second magnet 70 is illustrated as being against the raisedportion 56 around theopening 46, thereby closing theopening 46, even if opening 46 were open, the liquid still would not leak from thefirst housing 12. - It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Thus it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
