Do you mean the object that some say looks like a *flute*? One of the instruments of physicke associated with bathing is a bladder for inserting herbal washes and medicines into the "matrix". This tool was called a "syringe". I've been searching for a picture of this instrument, but all I've found to date is the description. There is a second type that looks something like a child's wooden top that was used for inserting suppositories into the "foundament" (you guessed it). Until I find a picture of the "syringe" bladder, I can't be certain, but it's a good probability.
