Atrion stock is down 64% from its ATH. Does anyone know much about this company?

Hi there, I saw this stock ATRI down quite a bit lately but their balance sheet looks pretty solid and their revenues and profits seem to be holding up. The company sells medical products for fluid delivery, cardiovascular and ophthalmology markets. Does anyone own or have this stock on their watchlist and know much about the company and why the price is falling so rapidly? $Atrion(ATRI.US)$
