A catheter anchoring system (10) is provided to securely anchor to a patient's skin a catheter (14) and fluid supply tube (12) interconnection. The anchoring system (10) comprises a retainer (20) configured to receive a catheter adaptor (22) in a variety of positions. The adaptor (22) interconnects the catheter (14) and the fluid supply tube (12). In one embodiment the adaptor (22) has a radial recess that circumscribes the adaptor (22). The anchoring system (10) additionally includes a flexible, adhesive anchor pad (16) which can support a tube clip (24), as well as the retainer (20). The retainer (20) includes a channel (44) that is configured to receive the adaptor (22) in a snap-fit manner. The retainer (20) also includes a plurality of laterally arranged slots (50) or projections (400) that extend from a channel wall (46) and into the channel (44). Each slot (50) or radial recess is sized to receive and to capture at least a portion of the retainer (20) so as to inhibit the adaptor (22) from moving within the channel (44).

La présente invention concerne un système d'ancrage (10) qui permet de fixer solidement un cathéter (14) et le branchement du tuber d'alimentation (12) en fluides sur la peau d'un patient. Le système d'ancrage (10) comprend une pièce de retenue (20) conçue pour recevoir un adaptateur de cathéter (22) dans diverses positions. L'adaptateur (22) relie le cathéter (14) et le tube d'alimentation en fluides. Selon une réalisation, l'adaptateur (22) est limité par un évidement radial. Le système d'ancrage (10) comprend par ailleurs un patin d'ancrage adhésif et souple (16) qui peut supporter une attache de tube (24) ainsi que la pièce de retenue (20). La pièce de retenue (20) comprend un caniveau (44) dans lequel l'adaptateur vient s'encliqueter. La pièce de retenue (20) présente également une série d'encoches latérales (50) ou de saillies (400) qui dépassent de la paroi (46) du caniveau pénètrent à l'intérieur de la gorge (44). De par sa taille, chaque encoche (50) ou évidement radial peut recevoir et maintenir une partie au moins de la pièce de retenue (20) de manière à empêcher l'adaptateur (22) de bouger dans le caniveau (44).
