This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
泏 combines 氵 (water) with 出 (exit), but the exact historical development and original meaning are uncertain.
Water 氵 exiting 出 could suggest something flowing out, but the meaning is unclear, so treat this as a visual placeholder.
For チュツ, imagine water exiting a tube with a sharp 'chuts' sound: chuts -> チュツ, as the water spurts out.
