A catheter securement device which automatically deploys one or more sutures to secure a catheter without requiring the practitioner to manually suture the catheter to the self-suturing anchor device. A ratchet mechanism having one or more rotatable ratchet members which pivot and a ratchet member engagement spring which maintains contact between the teeth of the rotatable ratchet member and the teeth of the ratchet ring. An O-ring is provided to maintain the position of the sutures to minimize disruption of the sutures before deployment of the sutures. In one embodiment, a stationary base of the anchor device comprises a single molded member. In another embodiment a method of manufacturing the catheter anchor device comprising welding a rotatable ring and one or more bearing members of the catheter anchor device through access bores in the stationary base.

Dispositif de fixation d'un cathéter qui déploie automatiquement une ou plusieurs sutures afin de fixer un cathéter sans que le praticien n'ait à suturer manuellement le cathéter sur le dispositif d'ancrage à suture automatique. Un mécanisme cliquet, comprenant un ou plusieurs éléments cliquets rotatifs pivotant, et un ressort d'imbrication avec l'élément cliquet, qui maintient le contact entre les dents de l'élément cliquet rotatif et les dents de l'anneau du cliquet. Un anneau en O permet de maintenir la position des sutures afin de minimiser la rupture des sutures avant déploiement de celles-ci. Dans un mode de réalisation, une base statique du dispositif d'ancrage comprend un élément unique moulé. Dans un autre mode de réalisation, on met en oeuvre un procédé de fabrication du dispositif d'ancrage du cathéter consistant à souder un anneau rotatif et un ou plusieurs éléments de palier du dispositif d'ancrage de cathéter à travers des alésages d'accès dans la base statique.
