Abstract
ABSTRACT OF THE DISCLOSURE
The invention relates to valve type spout for a fluid container, especially for a pouch worn by a patient to collect fluid discharged from a surgically formed stoma at his abdominal wall. Heretofore, such valve type spouts have been rigid in construction and of uniform circular cross-section, their outlet ends being closed by removable valve caps. They suffer the disadvantages of becoming clogged during emptying, of having cap removal difficulties, of being without effective control of fluid drainage and of not readily accommodating attachment to external drains. These disadvantages are overcome by the invention, according to which the spout is flexible as has an inlet neck section of oval cross-section, to facilitate clamping thereof between the user's fingers to close the spout before the cap over the outlet end section is removed, thereby assuring control of the discharge through the spout. A flexible tubular coupling member for feeding an external collection unit readily attaches to the outlet end section and provides lea-proof connections with striations or mating ridges.

Description
1~6~5813 The present invention relates to a valve type spout for a fluid container. It i~ particularly suitable for a fluid container in the form of a stoma - appliance. Such an appliance i9 de~cribed in our co-pending Application No. 258,965 wherein the spout of this invention is de~cribed. The subject matter of this application has been divided out of the said Application No. 258~965.
After ostomy surgical procedures, it ls necessary for the patient- to wear an appliance to collect the fluid discharged from thQ s~oma which has been surgically formed at the abdominal wall of the patient.
Such appliances commonly include a flexible pouch for collecting urine which is discharged from the stoma.
Prior art drainage appliances include an outlet spout and valve structure which presents problems in the area of clogging as the pouch is periodically emptied. Generally, the prior art outlet structures ' used with drainage appliances include a spout stem of rigid tubular construction having an ope~ing therethrou~h of uniform circular cross-section. The spout stem is attachsd at one end to the lower section of th~
drainage appliance and a rem~vab}e valve cap is provid~d for closin~ the outlet end of the spout. The spout and valve structure of this design has the disadvantage that it can become clogged during emp~ying due to the presence of mucous in~the uri~e. This is especially so if the 3pOU~ further includes any center support in the passageway. With this construction, it is also ' .

difficult to remove the cap from the spou~ and empty the pouch with assurancQ that this is neatly accomplished.
Once the cap is removed, and even when it is only partially removed, fluid starts to drain and there is no mechanical way of controlling it.
Another limitation of the prior ar~ spou~ and valve structure is difficulty in aoc~ting or b~ing attached to external drainage conduits of varying construction. Attachment of the drainage appliances to external drains may, for example, be advantageous for night drainage or where the pouch is used in connection with a leg bag for wheel chair patients.
External drain collection units of different manufac-ture~ have different conduit constructionsO Theref~re, depending on which manufacturers' unit is used, it is generally necessary to provide a specially designed adaptor to connect the unit to the spout of the pouch.
According to the invention there is provided a valve type spout for use as an outlet on a fluid container, said spout being flexible in construction and comprising an inlet neck ~ection of oval cross-section to facilitate clamping thereof to close said spout; an outlet end section of circular cross-section having a spout opening; and a cap member adapted to be secured over said end section to close the spout opening. The preferably tapered oval shaped neck section may be clamped together between the user's fingers to seal the spout before the cap at the end is removed. This assures that discharge through the spout is controlled and not begun until the cap is completely removed.
Preferably a coupling member is provided for permitting attachment of the fluid contai~er to external collection units of different construction.
The coupling mlember can be readily attached to the spout in a sealed relation; and ~or this purpose in the preferred lembodiment b~th the coupling member and ~ ' ' : - . . ,. . ' - . ' . . : ' ' -.. .. . . . :.

ti5~3(3 spout are made of the same vinyl plastics material with the same durometer hardness. Both the coupling member and spout also may include striations or mating ridges which assure proper leak-proof connection to each other. Finally, the coupling member may be tubular in construction with the opening through it being of variable diameter to aco~aate external drain conduits of varying constructions.
In order that the invention may be more readily understood, a specific embodiment thereof will now be described by way of example and with reference to the accompanying drawings in which:
Figure 1 is a back view of a s~oma drainage appliance with which the present invention can be utilized:
Figure 2 is a cross-secti~nal view taken along the lines 2-2 of Figure 1 and showing a spout according to the present invention;
Figure 3 is a cross-sectional view taken along the lines 3-3 of Figure 3 showing the cross-sectional shape of the spout; and Figure 4 is a cross-sectional view showing the construction of the coupling member for the spout.
Referring to the drawings, Figure 1 shows the general construction of a fluid container in the f~rm of a drainage appliance, with which ths present inventi~n can be utilized. Generally, the appliance includes a pouch~i comprised of four superimposed layers of flexible material. These layers include two outside sheets 2 and 3 and two inside sheets 4 and 5. The sheets are sealed together along their peripheral edges, except along the lower edges of the inside sheets, to form the pouch. The flexible material is vinyl plastics having a thickness of 3 to 10 mils and the sheets are sealed together by radio-frequency techniques.
The pouch i3 divided into an upper section 6 and lower section 7 and the sections are defined by .: .. -: ~, :~- ~ - : :
.: - '; .
having the two inside sheets 4 and 5 terminate midway between the top and bottom of the pouch. The lower edges of the inside sheets shown at 8 and 9 extend from one peripheral side edge of the pouch to the other. With this construction, the upper section 6 of the pouch is formed by all four sheets while the lower section 7 is d~fined by extension of the outside sheets 2 and 3.
An inlet opening 10 is provided in the upper section of the pouch and communicates with the space between the two inside sheets. Drainage fluid from tha stoma is received through this opening. An adhesive backed flexible and circular disc 11 is sealed at its center around the inlet opening 10. This disc also has a central opening 12 overlying the opening 10.
As shown in Figure 3 the opening 12 is smaller in diameter than the opening 10. Its size may be enlarged up to the size of the opening 10 toacco~x~te stomas of larger size. The disc 11 has a peripheral section 13 with the adhesive backed side facing away from the pouch. A release paper 14 is removably attached to the adhesive backed side. Upon removal of the release ~ -paper, the disc is adapted to be adhered to the body of the individual around the stoma for attaching the appliance to the patient.
In ~he lower section of the pouch, an outlet opening generally designated at 15 is provided. This outlet opening communicates with the spacs between the two outside sheets for draining fluid collected in the bottom of the pouch. A spout in accordance with the present invention is provided for the outlet opening and will be described in more detail below.
In order to preclude or deter fluid collected ~5 in ths lower section of the pouch from splashing or passing upwardly between the two inside sheets 4 `
and 5 and boward the inlet opening 10, these inside sheets are :; . . . : . ~ :, , :

partially sealed together and to the outside sheets at 18 between the inlet opening 10 and their lower edges.
This sealing is effected along a zone, designated by the dash lines 16, whiCh i~ spaced ~rom and extends generally along the edges 8 and 9 of the inside sheets.
The sealing of ~he inslde sheets in this manner provides the necessary mechanism to enable their edges to function as a type of flutter valve. With this con-struction, these edges tend to close and stay closed as the lower section of the pouch expands with collected fluid. Thus, as the patient moves about, such collected fluid will not flow backwardly to the stoma to cause irritation or infection.
The outlet spout 29 of the present i~vention is fixed to the lower section of the pouch at the outlet opening 15. The outlet spout is made of flexible vinyl plastics material and is constructed with an inlet neck section 30 and an outlet end section 31. As shown in Figures 2 and 3, the inlet neck section is oval in cross-section and has a tapered opening 31 extending therethrough.
The vinyl plastics material from which the spout is made has a durometer hardness of between 65 and 75. The neck section of the spout is construct@d with a thickness of .078 inch and a median outside diameter of 0.5 inch. The neck section of the spo~t is also providad with a pair of spaced circumferentially ~nding d~E~cation ridges 35. These ridges provide a visual indication to the patient that the neck portion of the spout is to be squeezed between the ridges to effect clamping and sealing of the spout. This construction of the spout permits easy finger clamping of the neck section to completely close the spout.
This is desirable so as to permit control of the spout when emptying the drainage appliance.
As shown in Figure 3 the outlet end of the spout includes a valve cap 32O The cap is formed . .:: - . :.

?~j~jS8C3 integrally with the spout and connected thereto by a lanyard 33. An internal plug 34 is provided in the cap ?
for insertion into the spout openlng upon secuxing the cap to the spout~ This type of construction permits 5 the spout and cap to be made of flexible plastics material and still provide an adequate seal. The plu~
34 supports the wall of the spout opening so that the latter is properly sealed within the cap. The resiliency of the lanyard will automatically swing the cap out of 10 the path of the spout so that the patient can release the clamping pressure on the neck section to empty the appliance in a neat manner.
The spout is constructed by a separate molding operation with an integrally formed and outwardly 15 directed flange 36 at the inlet end thereof. This flange is provided for attaching the spout to the !
pouch of the dralnage appliance. The attachment is `
effected by radio-frequency sealing and for this purpose, the flange 36 has a thickness no more than three or 20 four times that of the pouch material. For example, with the pouch material having a thickness of 3 to 10 mils, the flange of the spout may range between .10 and .020 inch. The vinyl plastics material of the spout is compatible with the vinyl plastics material 25 of the pouch for permitting this radio-frequency sealing.
A disadvantage of the prior art spout construc-tion i~ that the spout is constructed with an opening of uniform cross-section. In some prior art construc-tions, the spout even includes center support structure 30 for providing more rigidity to the spout. Since urine contains mucous this type of prior art construction tends to become blocked. With tha present tapered construc~ion of the spout and with the unobstructed opening therethrough, this problem is avoidad entirely 35 and complete drainage of the appliance can be quickly effected.
In som2 situations, it is necessary or :

desirable to connect the drainage appliance to an ex~
ternal collection unit. For example, during the night such a connection may be desirahle. To effect this connection, the cap 32 is removed from the spout and a tubular coupling member shown at 37 in Figure 4 is connected~ This member is formed of the same vinyl plastics material as the spout with the same durometer hardness. As shown in Figure 4 the coupling member has an internally striated or ribbed section 38 extending ci~cumferentially around the opening 39 through the coupling member. This ribbed section is adapted to mate with a similar externally ribbed section 40 formed on the outlet end of the spoutO In addition, the coupling member at its ribbed end is constructed of a thickness sufficient to make it relatively rigid as compared to the spout. This construction facilitates connection of the coupling member to the spout by simply pushing it on. Also, the ribbed section provides a friction fit of the coupling member to the spout for a fluid tight connection therewith.
The free end of the coupling member is adapted to be connected to external conduits of a fluid collection unit~ In the preferred embodiment and for purposes of aco~xdating external conduits of different -~
sizes, the opening through the coupling member tapers in cross-section as measured i~ the direction extending toward the free end thereofO This tapered construction is shown at 41. With this taper and with the flexible ' !
nature of the coupling member, insertion of an external conduit 42 having the size and tapered construction as shown in Figure 4 will at some point intermediate the ends of the tapared section 41 effect a frictional sealed engagement in the coupling member. It will be appreciated that external conduits of different diameters will effect the same type of sealing as shown in Figure 4O Thus, the coupling member can accommodate coupling to drainage units of different manufacture.

o As an example of a presently preferred con-struction of the coupling member, it is constructed with a total length of 1-9/16 inches and an outside diameter as its ribbed end of 11/16 of an inch.
The tapered opening through the coupling member extends for about 1 inch and is formed with a taper angle of about 5~. The median diamete!r of the opening is .320 inch while the minimum diameter is the same as the spout opening and measures .218 inch.
