P-Valve developments

dlegros · May 6th, 2006, 09:46 PM

Well, not exactly P-Valves, but sheath/condom catheters.

Found an ad in a journal at work for a company called BioDerm.

They are marketing a new type of external catheter that only attaches to the glans (the bell-end

) and can stay in place for up to 3 days

Silver inbound here Dom...you should start marketing them!!

Looks like an excellent idea. The question is how durable it is and how hard you can "pull" the catheter without detaching it. If I can get a sample I will try it.

Appologies if I appear a prud....but that looks painfull and a bit close to the Major for my liking!!

My samples have arrived and Ill be doing a two day test on the 19th and a three day on the 123 July.

Ill let you know the results.

They are expensive at 7.50 each (I think) but you leave them on for the whole trip

. Seeing as my diving is usually a minimum of two days it works out only slightly more expensive than the £2.50 catheters i normally use. the advantage is apparently comfort and no problems with cold water shrinkage (if you know what I mean.

Whilst for your average dive I would imagine they would be considered too expensive I think they would still be a viable consideration on long dives where spending a few hours in a urine soaked under suit may be less than optimal. Ironically on all my dive where I am expecting 120min + run times I am about as hydrated as i can be so i end up peeing a half a dozen or more times during deco.

I had seen these last year. Then they were not giving out samples. The smallest order was 30 at $230UDS. Little too pricey for my blood then. Like to try them now they are doing samples.

Thanks for the heads up!!

I've tried them. They are a little scary tbh, as they are stick as hell, and there's no taking the things off without solvent from the manufacturer (seriously) or a long soak in the bath ( I can vouch that this works too

).

they are fiddly to put on, and you get once chance to get it right, or have a useless piece of plastic stuck to the side of your unmentionable until your next bath

However, they do the job once they are on. They are far more secure than normal catheter condoms.

The price, however, at about £7 each, hurts about as much as taking them off

These do indeed work fantastically well, and as Garf said, they stick like sticky the stick insect on a very sticky day!! Had it on all day (and overnight) and it was still sticking like a limpet the next day. If you can stomach the price then go for it.

I wrote a little report here
