An ostomy is a surgical procedure in which an organ, for example the colon or a portion thereof, is removed and the digestive tract is attached to an opening surgically created in the abdominal wall, thereby, allowing digested waste to pass through the abdomen. Examples of ostomies include colostomies, ileostomies and urostomies, amongst others. Typically, the waste is then collected by an impervious bag that is secured over the opening. The opening that results from a colonectomy, or other similar procedures is known as an a “stoma,” and the impervious bag that collects the digestive waste is generally known as an ostomy bag.
An individual who has had a colostomy, ileostomy or the like typically empties the ostomy bag one or more times a day. Additionally, there are varying procedures for irrigating the stoma, which may be done on an about daily basis to maintain good health and sanitation. An ostomy is typically irrigated by applying warm flowing water into the ostomy, maintaining it for a predetermined amount of time and then allowing the water and any waste to drain there from.
In one exemplary embodiment, a manifold for ostomy bag irrigation is disclosed. The manifold may include an inlet member having a channel defined therein, a T-member having a channel defined therein and in fluid communication with the inlet member, a left tube having a plurality of apertures defined therein and having one end coupled to the T-member, a right tube having a plurality of apertures defined therein and having one end coupled to the T-member, a left cap having a channel defined therein and coupled to the second end of the left tube, and a right cap having a channel defined therein and coupled to the second end of the right tube.
In another exemplary embodiment, a method of utilizing a manifold for ostomy bag irrigation in conjunction with an ostomy bag is disclosed. The method may include defining a passage between the inner cavity of an ostomy bag and the exterior of the ostomy bag, coupling a right tube and a left tube to a T-member, inserting the right tube, left tube and T-member into the inner cavity of an ostomy bag, coupling the T-member to an inlet member disposed on the exterior of the bag via said passage, and adhering the inlet member and T-member to the ostomy bag such that a liquid-tight seal is formed.
In another exemplary embodiment, a method of irrigating an ostomy bag is disclosed. The method may include applying positive liquid pressure to the inlet member of a manifold for ostomy bag irrigation that is coupled to an ostomy bag, splitting the positive liquid pressure between a right tube and a left tube, the right tube and the left tube each having a plurality of apertures defined therein, and directing the positive liquid pressure through the plurality of apertures into an inner cavity of the ostomy bag.

Aspects of the invention are disclosed in the following description and related drawings directed to specific embodiments of the invention. Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention. Further, to facilitate an understanding of the description discussion of several terms used herein follows.
As used herein, the word “exemplary” means “serving as an example, instance or illustration.” The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiments are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms “embodiments of the invention”, “embodiments” or “invention” do not require that all embodiments of the invention include the discussed feature, advantage or mode of operation.

First tube 104, and left and right irrigation tubes 110, 112 may be formed from any flexible, resilient material known in the art. First tube 104 may also be sized to sealably couple with inlet member 102 and T-member 106, while left irrigation tube 110 may be sized to sealably couple with T-member 106 and left plug 114, and right irrigation tube may be sized to sealably couple with T-member 106 and right plug 116. Coupling between the above-described components may be facilitated by pressure fitting tubes 104, 110, 112 over the ends of inlet member 102, T-member 106 and left and right caps 114, 116. In one embodiment, the deformation of tubes 104, 110, 112 upon coupling with the ends of members 102, 106 and caps 114, 116 may be sufficient to maintain the coupling of the components of manifold 100 to each other when liquid pressure is applied to manifold 100 such that a liquid-tight seal exists. In another embodiment, an adhesive may be applied to the components of manifold 100 such that coupling is maintained under liquid pressure.
Left irrigation tube 110 and right irrigation tube 112 may each include a plurality of apertures 118. In one embodiment, apertures 118 may be positioned in diametrically opposed pairs, that is, for every aperture 118 disposed along the axial length of tube 110 or tube 112, there may be a corresponding aperture 118 disposed at the same axial position along the length of tube 110 or tube 112, but facing an opposite side of tube 110 or tube 112 in relation to the paired aperture. Such a structure can facilitate directing the liquid flow in equal and opposite directions from tubes 110, 112. In one exemplary embodiment, each of tubes 110, 112 may have seven pairs of diametrically opposed apertures 118 disposed along its axial length. In other exemplary embodiments, any number of apertures 118 may be arranged or disposed in any desired manner.
Inlet member 102 may have a channel 103 defined therein. Channel 103 may facilitate the flow of liquid through inlet member 102 into first tube 104. Channel 103 may be sized such that a desired rate of liquid flow and a desired liquid pressure are achieved during use of manifold 100. T-member 106 may have a channel 108 defined therein. Channel 108 may facilitate the flow of liquid from first tube 104 through T-member 106 and into left and right tubes 110, 112. Channel 108 may be bifurcated such that direction of liquid flow is facilitated in equal and opposite directions into tubes 110, 112. Left and right caps 114, 116 may also have channels 115, 117 defined therein. Channels 115, 117 may facilitate the flow of liquid from left and right tubes 110, 112, through left and right caps 114, 116 and out of manifold 100. Therefore, a liquid flowing from a liquid source coupled to inlet member 102 is distributed via manifold 100 and its constituent components into a plurality of liquid streams or sprays that may emanate from apertures 118, channel 115 of left cap 114, and channel 117 of right cap 116. The result, therefore, can be a plurality of liquid streams or sprays that facilitate evenly cleaning an ostomy bag that is being used in conjunction with manifold 100.
In another exemplary embodiment, as shown in
a-2b show exemplary installations of manifold 100 in an ostomy bag 200. Generally, ostomy bags are formed from a plurality of layers 202 that are sealed, by heat-sealing or any other methods known in the art, to form a liquid-tight border that defines an inner cavity 204. Additionally, ostomy bags generally include an inlet opening 208 and an outlet opening 209 (shown in

In an exemplary method of utilizing manifold 100 to irrigate an ostomy bag 200, positive liquid pressure 302 may be applied to inlet member 102 of manifold 100. The positive liquid pressure 302 may be applied from any liquid source, for example, but not limited to via a conduit that may be capable of coupling to inlet member 102 of manifold 100, such as a flexible hose having an end fitting that can threadably couple to inlet member 102. Under pressure, the liquid can be forced through inlet portion 102, tube 104 and may then be split via T-member 106 and directed towards left and right tubes 110, 112. The liquid can then be forced through the plurality of diametrically opposed apertures 118 (or any other desired arrangement of apertures 118), that are defined in tubes 110, 112 as well as through channels 115, 117 that are defined within left and right caps 114, 116. The resultant pressurized streams or sprays of liquid 304 that emanate from apertures 118 and channels 115, 117 may evenly and thoroughly clean any contents of interior cavity 204 of ostomy bag 200. The effluent 306 is then discharged from ostomy bag 200 via the bottom opening 209 of ostomy bag 200. Irrigation of ostomy bags with convenience, minimal effort and cleanliness may thus be achieved.
