[0071] Example - Flexibility Test

[0072] The flexibility of the link with a substantially inextensible string was tested. The connector such as Figure 10 shown in .

[0073] The test is performed in the Figure 13The standard three-point bending test rig shown is performed. The machine used was a conventional instron testing machine (not shown) which applied bending at a rate of 30mm / min. The test was stopped when the bend had reached 10mm. The support column for this three-point bending test consists of two rollers 101 and the force is applied by a third roller 102 connected to a load cell 103 .

[0074] The specimen consisted of a two-piece ostomy pouch. Initially, the release liner is removed from the base plate (sheet). The base plate is then mounted centrally onto the rollers 101 and the collection bag is attached to the base plate and locked using the locking ring.

[0075] The load used to bend the specimen by 10 mm was measured.

[0076] For comparison, an ...

[0081] Example - Compression Test

[0082] The ability to withstand compression was also tested.

[0083] An ostomy bag with a coupling having a locking ring in the form of a string element (eg Figure 8 shown). The pressure in the bag was measured. The highest pressure in the bag was recorded when air bubbles appeared, indicating a leak of the ostomy bag. For comparison, an ostomy pouch with a coupling with a conventional locking ring (in Figure 14 shown and described in WO9101118). This locking ring is sold by Coloplast A / S Click products.

Abstract

A coupling for an ostomy bag is provided. The coupling comprises a substantially non- extendable string functioning as locking ring in the coupling. The string is twisted by use of a tab when it is moved from an un-locked position to a locked position. A coupling as described can be made flexible and thereby more comfortable for the user.

Description

technical field [0001] The present invention relates to a mechanical coupling for an ostomy appliance, wherein the locking ring comprises a string of substantially inextensible material. Background technique [0002] With regard to surgery for many gastrointestinal disorders, one outcome in many cases is an abdominal stoma (such as a colostomy or an ileostomy) in the patient's abdominal wall for Evacuation of visceral contents. The discharge of visceral contents cannot be regulated at will. For this purpose, the user will have to rely on the appliance to collect the material emerging from such an opening in a bag which is then emptied and / or discarded at the appropriate moment. [0003] The ostomy appliance may be in the form of a two-part appliance comprising a base plate and a collection bag which may be coupled to and decoupled from each other by couplings. This means that the base plate does not need to be detached from the user's skin as often as is required for chan...
