Several months ago, on a Rusch double ballon nozzle appeared "discontinued" notice:
https://www.medtech3000.de/Ruesch-Doppelballon-Darmrohr-nach-Gaul-Doppelballondarmrohr::8.html
But now this appears on all interesting nozzles on this site:
https://www.medtech3000.de/Doppelballon-Darmrohr-mit-2-Geblaese-Darmkatheter-Ballondarmrohr::409.html
https://www.medtech3000.de/Doppelballon-Darmrohr-Set-2-Stueck-2-Geblaese-Darmkatheter::484.html
And even more bad news:
Single balloon nozzle is not in list anymore.
There is a little hope that it is product line update, and in time we will see new products.
But usually new products appear before old ones discontinued.
I can't find another suppliers that sales this nozzles.
Moreover, currently there is only couple of cleanstream inflatable nozzles on ohn, amazon and other well known web sites.
Honestly, i'am in panic.
