Hello ostiboy.
I agree with you about the cost of these things – and most things that are medical. For the person who need to purchase such items the costs seem ridiculously high. However, I also agree with Alex, who rightly points out that one-off or rarely bought items tend to be expensive because of the development costs compared with the likely return in profits.
Here is the dilemma: If we want or need research and development, then ‘someone’ needs to pay for it.
As a potential ‘user’ of such items, I would never be able to afford to purchase them myself so, my answer is to design and make them myself. (usually out of whatever might be available in my ‘shed’).
I’ve mentioned before that I make my own base plates; I have also made my own pressurised water dispenser for irrigation out of an old garden sprayer, both of which have worked perfectly well for years. Stoma-guards are no different in this respect, as long as you know what it is you want from them. Plastic is really easy to mould into almost any shape when gently heated, so all you need to do is make a mould to melt it around. However, I have found that fibreglass tends to be easier to work with when experimenting because you can get a basic shape and add bits to it afterwards if you think of something better. Not to be daunted by making stuff one’s self, very often what you are looking for is possibly/probably being used in some other capacity, and as long as you know what shape it is (I draw it out), then you can keep an eye out for such a shape in the many plastic containers and devices in the supermarkets and DIY stores.
I have a perfectly adequate stoma guard which is a simple addition to my baseplates, and that is a 90% water waste bend, which fits onto a short piece of appropriate pipe attached to the baseplate. This device, not only safeguards the stoma, but it guides the output away from the stoma and into the container (bag or sleeve whichever I’m wearing at the time). It cost next to nothing to make in terms of materials, but if I was to count my thinking/designing/development/searching and DIY time the costs would rise astronomically.
Alternatively, if you are lucky enough to have a charitable ‘engineering’ group nearby (as we have in our town), then you could explain the problem and ask if they might make you whatever you require.
These groups are usually made up of retired engineers and DIYers who love a ‘challenge’ for a good cause. My own expertise has been in reconditioning/recycling wheelchairs, which are not always available on the NHS. It is surprising how many people/carers need a wheelchair for the people they care for, but they cannot afford to buy a new one, and sometimes they only want to borrow one for a holiday or day’s shopping trip.
I hope you manage to resolve your needs soon.
Best wishes
Bill
