So I managed to have a look at the video via linkedin.
My first impressions were that we need people like this to be inventing stuff that 'might' work effectively and take us forward.
However, at present I irrigate and use a stoma plug, so this will be what I am comparing this device too.
Dr. armstrong says that there are no 'caps' - but then goes on to place a plastic cap over the device which sticks out considerably more than the thin plastic wafer on the stoma plug; Also, the stoma plug has small air vents so that gas can escape relatively easily. We know (from experience) how gas can cause all sorts of problems, including 'blowouts', bringing output with it once the 'cap' is dislodged. If gas builds up behind this device, then it will either be painful, or there will be a 'disaster' waiting to happen. My own stoma plugs intermittently get ejected from the stoma along with gas and sometimes faeces. However, The baseplate stays in place long enough to get to facilities where I can rectify the problem. It might be useful to explain that I wear an irrigation sleeve at nights and sometimes this is blown up like a balloon with gas. Anything that does not allow that gas free passage will potentially cause a problem.
I would also want to know how it will cope with peristomal hernias. If these are just behind the stoma outlet, then the internal part of the device is likely to be distorted or the hernia may be damaged. At present, my stoma plugs are made of porous material that 'goes with the flow' so to speak and, if there is undue pressure, they get expelled without causing any damage.
On the surface, this does seem to be a great idea, but it needs some real-life trials and some honest feedback from participants in those trials.
Hopefully, we will hear more about this product as it goes into the trial phase.
