::Also, it's a real surname (I found a "de Pooter"), and also that of the main character/writer (Charles Pooter) in The Diary of a Nobody, which seems to be a more researched topic than an aspirator gun.  So perhaps the wrong end of the stick is what we have here; I would think on the basis of notability, the book trumps the item.  I think that we should therefore change this to "aspirator gun" and create a semi-pro'd dab page to deal with the slang and other uses of the word.
