Abstract: A drinking aid device which is used for fluid intake, in particular for elderly people, patients and the like. The user receives the liquid from a valve assembly with the assistance of a mouthpiece member. The valve assembly includes an upper lid member, a lower housing member and a closure member which is disposed between the lid member and the housing member. The closure member has one or more apertures and is movable by suction between an open position and a closed position in a check valve fashion for allowing the liquid to flow therethrough.

Abstract: A tap for aseptic packages of the type which contain solutions and, in particular, solutions for medical applications. The type has a body, a packaging penetrating tip extending from the body, a liquid passageway extending from the tip and through the body for dispensing liquid from the package and a fluid passageway extending from the tip and through the body for admitting make-up air to the package interior. A cylindrical member of resilient material is positioned between the tap body and its penetrating tip and is insertable through the package wall in trailing relation to the tip. The resilient member is selectively compressed along its cylindrical axis to expand within the package and engage the wall to seal the orifice formed by the tip on penetration of the package wall and to secure the tap to the package.

Abstract: A catheter is provided with a first radiographic contrast strip extending helically on or in the catheter wall with a constant pitch and a second such strip which is either disposed on a longitudinal generatrix of said wall to intersect said first strip once per convolution thereof or extends helically at the same constant pitch but in the opposite direction to intersect said first strip twice per convolution on respective opposite longitudinal generatrices.
