Description
Drainage Pouch for Ostomate with Closure of Its Inlet Technical Field
The present invention relates a drainage pouch for ostomate with closure of its inlet. Ostomates have to wear a drainage pouch for the collection of their organic waste exiting the stoma created as a result of a colostomy or of an ileostomy. Said drainage pouch is usually obtained with front and rear sheets of thermoplastic material, shaped and sealed together in such a way as to be sealed at their periphery. In the rear sheet of the pouch is usually obtained an inlet which, according to various alternative means, is applied at the stoma. Through said inlet, organic waste passes from the patient's body to the drainage pouch.
Background Art hi drainage pouches currently available on the market, this opening is always through, both, obviously, when it is installed on the stoma, and after use, while it is detached from the patient's body, before its disposal in the garbage.
Now, it should be considered that one of the major problems encountered by ostomates is the removal of the drainage pouch filled with excretes. When it is removed, a bad smell is perceived and excretes, i.e. the material it contains, may even spill out. Disclosure of Invention
The main object of the present invention is to prevent the removal of a drainage pouch from the body of an ostomate from creating problems, such as the emanation of unpleasant odours and the spillage of the excretes, and embarrassment in the person who wears it. The aforementioned object is achieved by providing a drainage pouch for ostomate, made of sheets of laminar material, peripherally shaped and sealed to form a rear wall provided with an inlet whose diameter is such as to be applied around the stoma of an ostomate, and a front wall oriented opposite to the rear wall, which, from a general viewpoint, is characterised in that the drainage pouch has, applied around said inlet on the inner side of the rear wall, a closure device able to close the passage port of said inlet when it is actuated by manual control means, which are housed inside the drainage pouch in a protective member which isolates them from the rest of the drainage pouch and are projecting outside it.
Description of the Drawings
Further characteristics and advantages shall become more readily apparent from the indicative, and therefore non limiting, description of a preferred, but not exclusive embodiment as illustrated in the accompanying drawings, in which:
- Figure 1 is a vertical cross section of a drainage pouch according to the prior art, whereto is applied a closure device according to the present invention;
- Figure 2 is an enlarged top perspective view of the closure device of Figure 1 in open position, as seen from the interior of the drainage pouch;
- Figure 3 is a vertical section of the closure device of Figure 2;
- Figure 4 is an exploded perspective view of the closure device of Figure 2; - Figure 5 is a partially exploded and further enlarged perspective view of the closure device of Figure 4;

Description of the Illustrative Embodiments
With reference to Figure 1, a vertical cross section is shown of a drainage pouch 1 of a generally known kind, disclosed for example in US Patent 5,961,502. The drainage pouch is of the kind in a single piece, having sealing means that extend around the opening to seal the pouch to the wearer's skin. Alternatively, although it is not shown, the closure device according to the invention can be applied to a drainage pouch in two pieces, also known and not further described herein. The drainage pouch 1 is made of sheets of laminar , e.g. thermoplastic, material. The sheets are shaped peripherally and sealed to form a rear wall 2 and a front wall 3. The rear wall 2 is provided with an inlet 4 to be applied at the stoma of an ostomate (not shown in the figures). The front wall 3 is oriented opposite to the rear wall 2. m the rear wall 2 is provided an adhesive layer 4 to the patient's skin and, additionally, around the inlet 4, a support and seal collar 6.
According to the invention, the drainage pouch 1 has, applied around the inlet 4 on the inner side of the rear wall 2, a closure device 7. As will be described in the remainder of the description, the closure device 7 is able to shut off the passage port of the inlet 4. Reference is made to Figure 2, which is an enlarged top perspective view of the closure device 7 of Figure 1 in the open position. The closure device 7 is shown separate from the drainage pouch and as if it were seen from the interior of the pouch itself. Differently from Figure 1, the closure device 7 is shown set down on a base element 18, with annulus shape, which delimits the inlet 4 of the drainage pouch 1. With reference to Figures 3 and 4, which are respectively a vertical section and an exploded perspective view of the closure device of Figure 2, the closure device 7 according to an embodiment of the present invention comprises a tubular element 8, whose diameter is greater than the diameter of the inlet 4. The tubular element 8 is bend back on itself in accordion fashion, as shown more clearly in Figures 5 and 6, which are respectively a partially exploded and further enlarged view of the closure device of Figure 4, and a partial section thereof. In order to remain bent back on itself, the tubular element 8 is made with a material chosen among those used in this sector of the art, in order to have adequate characteristics of elasticity and flexibility. For example, it could be made of latex. Obviously, the bending of the tubular element 8 back on itself could be different, e.g. promoted by a tapered shape thereof.
The tubular element 8 has an end 9 attached to the inner side of the rear wall 2 by means of the base element 18. The other end 10 of the tubular element 8 ends with a sheath 11. The tubular element 8 is enclosed within its covering means, thereby being able to project outside them in the closing actuation of the device 7. The covering means of the tubular element 8, elastically deformable, substantially have toroidal shape. They comprise a lip 19 and a barrier 20. The L shaped lip 19 is fastened with its base peripherally to the edge of the inlet 4. The L shaped lip 19 has its core curving towards the interior of the drainage pouch 1 at the opposite part of the inlet 4. The barrier 20, which has a G shaped profile, is fastened at its base adjacently to the end 9 of the tubular element 8. Its free end is oriented towards the port of the inlet 4.
In an open position of the device, i.e. when the tubular element 8 is contained inside the covering means, the latter are in such a relative position that the lip 19 overhangs the free end of the barrier 20, as shown in particular in Figures 2, 3 and 6. To place the closure device in the active position, manual control means are provided which comprise a pair of strings 12, 13. The strings 12, 13 are inserted in the sheath 11 and they separately project out of two respective slots 14, 15 obtained therein. Preferably, the slots 14, 15 are obtained in diametrically opposite portions of the sheath 11.
Imparting a traction on each of the strings 12 and 13 in opposite directions, the sheath 11 exits the covering means passing between the lip 19 and the barrier 20, creating a screen as shown in Figures 7 and 8, which are top perspective views of the closure device of Figure 1 in closed position, as seen from the interior and, respectively, from the exterior of the drainage pouch. The end 9 of the tubular element that is opposite to the sheath 11 remains attached to the rear wall 2 directly or through the base element 18. To prevent the strings 12 and 13, in their part inside the drainage pouch 1, from coming in contact with the materials excreted through the stoma, a protecting member is provided, comprising a pair of channels 16, 17 shown only partially in the figures. Each of the channels 16, 17 is joined at one of its ends to the covering means of the tubular element 4, in particular to the barrier 20 at one of the two slots 14, 15 of the sheath 11, wherefrom project, respectively, the strings 12, 13. Although it is not shown in the figures, the other end of the channels 16, 17, opposite the one in contact with the barrier 20, is attached to one of the two walls, front and rear, 2, 3 of the drainage pouch 1. hi this way, a passage port is thus delimited to house within it one of the pair of strings 12, 13 so that its free end projects out of the drainage pouch 1 and can be pulled, each string from mutually opposite sides, to close the end 10 of the tubular element 8. In use, the user, before detaching the drainage pouch, pulls the strings 12, 13, thereby closing the device positioned in the inner side of the inlet 4. The strings 12, 13 remain pulled thanks to friction with the channels 16, 17 and with the sheath 11. The tubular element 8, after exiting clean and undamaged from the covering means 19, 20, creates a screen on the port of the opening 4. This prevents material and unpleasant smells from issuing out of the drainage pouch, and its interior is also advantageously obscured from view.
As stated previously, it should be kept in mind that the closure device according to the present invention is not limited to the drainage pouch shown herein, but can be applied substantially to any type of pouch.
