<p>A low profile ostomy coupling system consisting of two circular coupling members (1,2) and a 'handcuff shaped' locking device (3). The first coupling member (1) consists of a polymeric flange (4) with an upstanding projecting rib (5), provided with a small ridge (6) alongside the outer circumference, and it is designed to be welded on the top layer of a skin friendly pressure sensitive adhesive (21) to be adhered to a patients skin. The second coupling member (2) consists of a radially outwards projecting 'U' shaped channel with uneven legs. The aperture of the second coupling member is sized to fit easily around the first coupling member, lightly jammed in between the flange and the small ridge (6) around its projecting rib. The channel is designed to fit the profile of the 'handcuff' locking device (3) and its largest leg is meant to be welded to a stoma appliance such as stoma pouch. The 'handcuff' locking device has a hinge (10) for easy positioning around the second coupling member, whereby its body profile fits exactly the channel of the coupling member (2). The ends of the 'handcuff' consist of a male (11) and a female (12) part, together forming a dual locking mechanism. The primary locking position keeps both arms of the handcuff together without pressure on the coupling members. The second locking position will be activated by putting more pressure on the male and female ends, thus squeezing the two coupling members together, which in practice will create a secure and leak proof connection between a stoma appliance and a body side wafer. To unlock, one simply pushes a button (15) and due to its spring in the hinge (16), the handcuff will unlock and slip back into its primary locking position.</p> |
