CA 2653568

The invention relates to an infusion set for introducing liquid medicaments into the body of a patient. The infusion set comprises a first structural part (1) with a cannula (2) protruding from it, and a second structural part (3) with a connection port (4) for the connector (5) of a supply line (6). The first structural part (1) and the second structural part (3) are designed in such a way, and connected to each other in such a way, that they are inseparable and are able to rotate relative to each other and, in each relative position of rotation, form a channel (7) for delivering a liquid from the connection port (4) to the cannula (2) or for withdrawing a liquid from the cannula (2) to the connection port (4). In addition, the connection port (4) is arranged on the second structural part (3) in such a way that the coupling and uncoupling of the connector (5) in each case take place in a direction transverse to the longitudinal axis of the cannula (2). By means of the invention, it is possible to make available infusion sets which offer a high level of comfort to the wearer and which at the same time are safe against operating errors.

L'invention concerne un kit de perfusion servant à introduire des médicaments liquides dans l'organisme d'un patient. Le kit de perfusion comprend un premier composant (1) avec une canule (2) qui en dépasse et un deuxième composant (3) avec un orifice de raccordement (4) pour le raccord (5) d'une ligne d'alimentation (6). Le premier composant (1) et le deuxième composant (3) sont conformés et reliés l'un à l'autre de telle façon qu'ils ne peuvent pas être séparés et qu'ils peuvent tourner l'un par rapport à l'autre et forment dans chaque position de rotation relative un conduit (7) qui permet d'amener un liquide de l'orifice de raccordement (4) à la canule (2) ou d'évacuer un liquide de la canule (2) vers l'orifice de raccordement (4). En outre, l'orifice de raccordement (4) est disposé sur le deuxième composant (3) de telle façon que le branchement et le débranchement du raccord (5) se font chacun dans une direction perpendiculaire à l'axe longitudinal de la canule (2). L'invention permet de proposer des kits de perfusion qui offrent à la fois un confort élevé pour le porteur et une bonne sécurité contre les erreurs de manipulation.
