An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without meaningfully impairing fluid flow through the catheter. The anchoring system includes an anchor pad that adheres to the patient's skin and supports a retainer. The retainer releasably receives a portion of the catheter and includes one or more retention mechanisms. The retention mechanisms inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. In one mode, the retention mechanism is positioned within a channel of the retainer and includes at least first and second members that project from opposite sides of the channel. The members are arranged to cooperate with one another when the cover is closed so as to capture a structural portion of the catheter between the first and second members without substantially occluding an inner lumen of the catheter.

Un système d'ancrage fixe un cathéter au corps d'un patient et stoppe le mouvement axial du cathéter sans affecter sensiblement l'écoulement de fluide à travers le cathéter. Le système d'ancrage comprend une plaquette d'ancre adhérant à la peau du patient et portant un élément de retenue. L'élément de retenue reçoit de manière libérable une partie du cathéter et comprend un ou plusieurs mécanismes de retenue. Le mécanisme de retenue empêche le mouvement axial du cathéter par rapport à l'élément de retenue lorsque le cathéter y est fixé. Dans un mode de réalisation, le mécanisme de retenue est positionné à l'intérieur d'un canal dudit élément de retenue et comprend au moins des premier et second éléments dépassant des faces opposées du canal. Les éléments sont agencés pour coopérer l'un avec l'autre lorsque le couvercle est fermé afin de maintenir une partie structurelle du cathéter entre les premier et second éléments, sans occlure sensiblement une lumière intérieure du cathéter.
