Abstract

Described herein is a medical device with an opening system. The medical device is foldable from an open to a closed condition. It is secured in its closed condition. In certain embodiments, the medical device is an ostomy pouch.

First claim

What is claimed is:

1. An ostomy pouch comprising:
a. opposing walls having a cavity therebetween, the walls joined along their peripheries, and tapering to an outlet opening at the proximal end of the device;
b. first and second deformable reinforcing members attached to opposing exterior surfaces of said opposing walls, wherein each reinforcing member has two lateral edges deformable by manual application of pressure to said lateral edges, so as to radially distend the outlet opening, wherein the first and second deformable reinforcing members are offset from each other along a longitudinal axis, wherein the lateral edges of the first and second reinforcing members have corners with void space, and wherein each corner with void space is configured to receive a portion of a user's digit to facilitate the manual application of pressure to said lateral edges; and
c. first and second fasteners;
wherein the outlet is flexible and foldable from an open condition to a closed condition by one or more folds.

2. The ostomy pouch of claim 1 , further comprising a system for securing the device in the closed condition, the system comprising:
d. a security flap, wherein said flap is attached to the same exterior surface of one of said opposing walls as the second reinforcing member, distal to the opening of the outlet with respect to the second reinforcing member, wherein a portion of the flap extends freely from the exterior surface of the opposing wall on which the flap is attached; and
wherein the first fastener is attached to the same exterior surface of one of said opposing walls as said first reinforcing member, distal to the opening with respect to said first reinforcing member, and the second fastener is attached to the freely opened portion of said security flap, wherein the first fastener and the second fastener are capable of forming linkage when the outlet is in the closed condition.

3. The ostomy pouch of claim 1 , wherein at least one of the first fastener or the second fastener is a hook and loop fastener.

4. The ostomy pouch of claim 1 , wherein the first deformable reinforcing member is near the outlet opening, and the second deformable reinforcing member is distal to the outlet opening with respect to the first deformable reinforcing member.

5. The ostomy pouch of claim 1 , wherein the second deformable reinforcing member is near the outlet opening, and the first deformable reinforcing member is distal to the outlet opening with respect to the second deformable reinforcing member.

6. The ostomy pouch of claim 1 , wherein the first and second deformable reinforcing members differ in size.

7. The ostomy pouch of claim 1 , wherein the first and second deformable reinforcing members differ in shape.

8. The ostomy pouch of claim 1 , wherein at least one of the first deformable reinforcing member or the second deformable reinforcing member extends the entire width of the outlet opening.

9. The ostomy pouch of claim 1 , wherein at least one of the first fastener or the second fastener extends the entire width of the outlet opening.

10. The ostomy pouch of claim 1 , wherein the first and second fasteners differ in size.

11. The ostomy pouch of claim 1 , wherein the first and second fasteners differ in shape.

12. The ostomy pouch of claim 1 , wherein the first and second fastener form a linkage after two lateral folds of the outlet.

13. An ostomy pouch comprising:
a. opposing walls having a cavity therebetween, the walls joined along their peripheries and tapering along a longitudinal axis to an outlet opening at the proximal end of the device;
b. a deformable reinforcing member on one exterior surface of said opposing walls, near the outlet, said reinforcing member having two longitudinally-extending lateral edges positioned on opposite sides of the longitudinal axis, wherein the reinforcing member is deformable by manual application of pressure to said lateral edges toward the longitudinal axis, so as to radially distend the outlet opening, wherein at least one of the longitudinally-extending lateral edges of the reinforcing member is notched; and
c. a first fastener and a second fastener attached to opposing exterior surfaces of said opposing walls, wherein one of the first fastener or the second fastener is near the outlet opening;
wherein the outlet is flexible and foldable from an opened condition to a closed condition, and wherein the first fastener and the second fastener are capable of forming a linkage when said outlet is in the closed condition.

14. The ostomy pouch of claim 13 further comprising a system for securing the device in the closed condition, the system comprising:
d. a security flap, wherein said flap is attached to one exterior surface of said opposing walls, distal to the opening of the outlet with respect to said deformable reinforcing member, wherein a portion of the flap extends freely from said one exterior surface of said opposing wall to which the flap is attached;
e. a third fastener attached to one exterior surface of said opposing walls, and
f. a fourth fastener attached to the freely opened portion of the security flap, wherein said third fastener and said fourth fastener can form a linkage when said outlet is in the closed condition.

15. The ostomy pouch of claim 14 , wherein at least one of the first fastener, the second fastener, the third fastener, or the fourth fastener is a hook and loop fastener.

16. The ostomy pouch of claim 13 , wherein the first fastener is attached to the deformable reinforcing member having two lateral edges and is deformable by manual application of pressure to said lateral edges, so as to controllably distend the outlet opening.

17. The ostomy pouch of claim 13 , wherein the second fastener is attached to the deformable reinforcing member having two lateral edges and is deformable by manual application of pressure to said lateral edges, so as to controllably distend the outlet opening.

18. The ostomy pouch of claim 13 wherein the first and second fasteners form a linkage after two lateral folds of the outlet.

19. The ostomy pouch of claim 14 , wherein the third and fourth fasteners form a linkage after two lateral folds of the outlet.

20. An ostomy pouch comprising:
a. opposing walls having a cavity therebetween, the walls joined along their peripheries, and tapering to an outlet opening at the proximal end of the device;
b. at least one reinforcing member attached to an exterior surface of one of said opposing walls, wherein the reinforcing member has two lateral edges deformable by manual application of pressure to said lateral edges, so as to radially distend the outlet opening, wherein the lateral edges of the at least one reinforcing member have corners with void space, wherein each corner with void space is configured to receive a corresponding portion of a corresponding manual digit to facilitate the manual application of pressure to said lateral edges; and
c. first and second fasteners;
wherein the outlet is flexible and foldable from an open condition to a closed condition by one or more folds.

21. The ostomy pouch of claim 20 , wherein the at least one reinforcing member comprises:
a first reinforcing member positioned near the outlet opening, wherein the first reinforcing member comprises distal corners with void space; and
a second reinforcing member positioned distally of the first reinforcing member, wherein the second reinforcing member comprises proximal corners with void space;
wherein a first distal
