Abstract

1. Use of polystyrene polymers for the production of drip chambers for transfusion apparatus, the upper part of the drip chamber consisting of polystyrene homopolymers or copolymers, characterized in that a mixture or alloy of a) polystyrene homopolymers or copolymers, with b) thermoplastic rubbers based on styrene-butadiene-styrene or styrene-isoprene-styrene block polymers are used for producing the flexible lower part of the drip chamber.
