DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] FIGS. 1-7 show an ostomy pouch 100 installed on a person P (“the ostomate”) about its stoma S and covered with an ostomy pouch protector 12 according to the present invention. More particularly, the ostomy pouch 100 is of the conventional type and comprises a bag 102 provided with a stoma opening 104. A bag collar 106 is formed about opening 104. The collar 106 is equipped with a disc-shaped wafer 108 that is pierced near its center by the person to form a hole 110 to receive the stoma S therethrough. The collar 106 is applied against the person's abdomen A such that the wafer 108 will adhere to it by means of an adhesive that is provided on the wafer's rear face.

[0039] The bag 102 is oblong and comprises a bottom end 112 that has a drainage opening 114 fitted with a closable tail closure 116, for example in the form of a foldable Velcro™ seal clamp of known construction, or other equivalent closure. A filter 118, such as an active carbon filter, can be provided on bag 102.

[0040] Alternate ostomy bags of known construction can be used, including one-piece or two-piece systems.

[0041] According to the present invention, the ostomy pouch protector 12 is provided to protect the ostomy pouch 100 from water or other external threats, as detailed hereinafter.

[0042] Ostomy pouch protector 12 comprises an impermeable envelope 30 defining an enclosure 31 for receiving an ostomy pouch therein. Envelope 30 can be made of any suitable impermeable material that protects the ostomy pouch against fluids, including plastic, silicone, rubber, or the like.

[0043] Ostomy pouch protector 12 comprises a biasing attachment for releasably attaching the envelope 30 to person P. In the embodiment shown in FIGS. 1-7, the biasing attachment comprises an elastic strap 34 for attachment to the person's body. More particularly, strap 34 is in the form of a belt, and has two ends 34a, 34b sewn into loops for attachment to corresponding rigid oblong side rings 36a, 36b that are integrally linked to a strap collar 36. Strap 34 is preferably made of a stretchable elastic material.

[0044] Envelope 30 comprises an ostomy opening 38 allowing access into enclosure 31 and allowing the ostomy pouch 100 to connect to the stoma S through the ostomy opening. More particularly, ostomy opening 38 is wide enough to allow the bag collar 106 and the wafer to engage the person's abdomen. Envelope 30 defines a rim 40 that is the zone of envelope 30 located immediately about ostomy opening 31. Ostomy opening 38, circumscribed by rim 40, is consequently as wide as, or wider than, the bag collar 106 for allowing the proper engagement of bag collar 106 against the person's abdomen.

[0045] Envelope 30 also comprises a skirt 42 that extends away from rim 40. Skirt 42 extends outwardly away from opening 38, with rim 40, strap collar 36 and rings 36a, 36b being located between skirt 42 and the main body of envelope 30.

[0046] Envelope 30 is attached to strap collar 36 in a way to operatively allow installation and use of envelope 30 as detailed hereiafter. The attachment of envelope to strap collar 36 can simply rely on the resiliency of the material being used, e.g. such as that of silicone. If the envelope 30 and skirt 42 are resilient enough, it is possible to insert strap collar 36 between the skirt and the main body of envelope 30 and the intrinsic resiliency of the material will keep strap collar 36 in place. Or, a more positive attachment of strap collar to rim 40 could be envisioned, such as an adhesive, stitches or the like.

[0047] In use, ostomy pouch protector 12 can be installed on a person that has its ostomy pouch 100 already installed on them, with wafer 108 adhering to the person's abdomen. To proceed with the installation of pouch protector 12, the person will first slide the belt strap 34 around their legs and up until strap is approximately at waist level and the pouch protector 12 is located approximately at the level of ostomy pouch 10. Flexible strap 34 will stretch to accommodate the person's girth. Then, the person will slide ostomy bag 100 into the enclosure 31 of protector envelope 30 through opening 38. Since opening 38 is wider than collar 18, and since both ostomy bag 100 and envelope 30 are made of flexible material, this insertion is made easy. Bag 14 is entirely inserted into envelope 30 until rim 40 is positioned around the pouch's collar 106. Strap 34 is concurrently adjusted by sliding it on the abdomen to have it extend approximately horizontally around the abdomen.

[0048] In an alternate embodiment, a belt buckle (not shown) could be provided on belt strap 34 for attachment and removal of belt strap 34 around the person's abdomen. The strap would then not need to be elastic.

[0049] Flexible strap 34 will pull strap collar 36 towards the person's abdomen, which will apply pressure against skirt 42 that will be forced into a watertight sealing engagement against the person's body. Since the material of envelope 30 is suitable impermeable, such as a suitable plastic, silicone or rubber, it is further possible to have skirt 42 create a suction effect on the abdomen, further enhancing the sealing relationship with the abdomen and concurrently preventing the envelope rim 40 that circles wafer 108 from moving relative to wafer 108, i.e. preventing rim 40 from accidentally sliding against wafer 108 which might undesirably force wafer 108 to dislodge from engagement against the person's abdomen.

[0050] Water and other fluids will consequently be prevented from entering envelope 30 due to the watertight seal created by skirt 42, resulting in an efficient protection of both the ostomy pouch 10 and the peristomal area. This allows the person to take their shower or a bath, or even to be submerged in pool water, without the ostomy pouch becoming wet, in particular the delicate wafer seal 108 that can be affected and weakened by water to the point of losing its sealing and supporting properties; and without bacteria forming in the peristomal area.

[0051] When the person is done bathing, showering or swimming, and has dried, they can remove the pouch protector 12 very easily, by tangentially inserting a finger under skirt 42, between rim 40 and their abdomen, to let air in and break the suction effect; and then by sliding envelope 30 away from their abdomen, with the ostomy pouch 100 concurrently exiting enclosure 31 through opening 38; and finally by sliding the strap 34 down along their legs until the pouch protector 12 is entirely removed.

[0052] FIGS. 8-11 show another embodiment of an ostomy pouch protector 48 wherein the biasing attachment is in the form of a garment, and more particularly a midriff swimwear 50 that can be worn like swim trunks or shorts on the person's lower abdomen A and legs L. Garment 50 can be made for a male or female person. Garment 50 is preferably made of an elastic, stretchable material such that it will stretch when the person slides it on.

[0053] According to this embodiment, envelope 30 is carried by garment 50 and more particularly the outer peripheral edge 52 of envelope 30 is sewn to garment 50 (without the stiches piercing through into enclosure 31 of course). Envelope 30 is installed on the interior surface of garment 50 so as to face the person's abdomen when it is worn. Ostomy pouch 100 can be inserted and retrieved from envelope 30 as described in the first embodiment, with the exception that the garment is slid or removed from the person P as any other pair of shorts or swimming trunks might be donned or removed. The garment 50 carries the envelope 30 and biases the skirt 42 against the person's abdomen for creating a watertight seal with a suction effect of the skirt 42 on the abdomen, as described in the first embodiment.

[0054] In both described embodiments, the role of the biasing attachment is consequently both to carry the envelope and to bias the envelope skirt 42 against the person's abdomen. The skirt 42 will create the watertight seal to protect the ostomy pouch 100 and its wafer's attachment to the person's abdomen.

[0055] The skirt is advantageously made of the same material as the envelope, such as silicone, plastic or rubber. The skirt and the envelope proper could alternately be made of different suitable materials, i.e. the envelope proper in a first material, and the skirt in a second material. In all circumstances, the material(s) chosen for both the envelope and the skirt should be made of a material that is suitable according to a person skilled in the art, including in regard to being fluid tight, biocompatible, resistant, etc. . . . .
