Abstract
Nipples for use in coupling various secondary coupling components including so-called Hansen couplings are disclosed in which the nipple includes a longitudinally extending cylinder which includes an outer recess on its outer surface which is adapted for engagement with a Hansen-type secondary coupling component including a locking element for engaging the outer recess, and in which the nipple includes threads located between the outer recess and the outer end of the longitudinally extending cylinder, which are adapted for engagement with a secondary coupling component including corresponding threads thereon. The disclosed nipples are intended to be used in order to couple dialyzer or similar diffusion and/or filtration devices to different tube systems which can include coupling components which are intended for throw-away use and/or for multiple usage.
