  • Publication number: 20070066942
    Abstract: 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. A suture retention assembly is provided to maintain the position of the sutures to minimize disruption of the sutures before deployment of the sutures.

  • Publication number: 20060095009
    Abstract: A self-suturing anchor device includes rotatable ring adapted to automatically deploy sutures to secure a catheter. The rotatable ring is utilized in connection with a ratchet mechanism which allows movement of the rotatable ring in a first direction while preventing movement of the rotatable ring in the opposite direction. The rotatable ring is also utilized in connection with a bearing member to facilitate smooth and efficient rotation of the rotatable ring. An extension saddle is utilized to provide a desired amount of displacement between suture securement points to minimize pivotal movement of the catheter. The rotatable ring is wider than its height to minimize kinking of the catheter tube and to relieve pressure when pressed between the patient and a support surface. In another embodiment, a plurality of scallops or other gripping members are utilized to facilitate easy gripping and rotation of the rotatable ring.

  • Publication number: 20060095008
    Abstract: A self-suturing anchor device includes a base having a securement mechanism. The securement mechanism includes one or more resilient pockets in which are placed a plurality of looped sutures. The securement mechanism and looped sutures facilitate automatic securement of a catheter relative to the self-suturing anchor device. In at least one embodiment, the looped sutures are also threaded through loops in another corresponding looped suture, such that each looped sutures slidably tighten in concert with one another. When at least a portion of the securement mechanism is moved, at least one of the plurality of looped sutures is tensioned and closes against a securement point on the catheter. A catheter can be secured in a self-suturing anchor device in a quick and efficient manner with minimal effort.

  • Publication number: 20050049548
    Abstract: An over pressurization relief apparatus having a manual over pressurization selector which allows a user to manually select from at least a first and second over pressurization limit. The over pressurization relief apparatus includes a pressurization chamber, a pressure relief mechanism, a seal, and a manual over pressurization selector. The pressurization of the pressurization chamber corresponds with the pressurization of the pressure infusion bag. The pressure relief mechanism prevents additional pressurization of the pressure infusion bag once the over pressurization limit has been reached. The seal is positioned between the pressurization chamber and the pressure relief mechanism to prevent the loss of pressurization from the pressure infusion bag when the pressurization in the pressurization chamber is less than the over pressurization limit.
