Self-suturing anchor device
View Patent ↗A catheter anchor device for use with a catheter includes an adhesive layer configured to be secured to the skin of the patient proximate the catheter insertion site, a stationary base secured to the adhesive layer, a rotatable ring coupled to the stationary base and circumscribing the stationary base such that the rotatable outer ring can be rotated by the user relative to the stationary base, a first suture including a loop portion and first and second ends, the loop portion looping around a catheter when the anchor device is in place relative to the catheter insertion site, and a pull handle including first and second separable pull tabs, the pull handle being coupled to the first and second ends of the first suture, the pull handle being configured such that actuation of the pull handle actuates first suture to secure the catheter relative to the rotatable ring.
1. A catheter anchor device, the catheter anchor device comprising:
a base;
a rotatable ring coupled to the base and arranged for movement relative to the base; and
a first suture and additional sutures coupled to the rotatable ring, the first suture including a loop portion and first and second ends, the loop portion looping around a catheter when the anchor device is in place relative to a catheter insertion site, the first suture being arranged relative to the base and catheter such that a predetermined rotation of the rotatable ring deploys at least the first suture to cause the loop portion of the first suture to engage a wall of the catheter and wherein additional rotation of the rotatable ring corresponds with a relative increase in tension of the first suture about the catheter;
means for tensioning a suture, the means serving to enable tensioning of at least one suture about the catheter; and
a ratchet mechanism operably disposed with respect to the rotatable ring, the ratchet mechanism comprising a rotatable ratchet member which maintains cooperative engagement of the components of the ratchet mechanism such that the rotatable ring is rotatable in a first direction and is not rotatable in a second direction.
2. The catheter anchor device of claim 1 , wherein the means for tensioning a suture comprises a pull handle.
3. The catheter anchor device of claim 2 , wherein the pull handle comprises first and second separable portions.
4. The catheter anchor device of claim 3 , wherein the separable portions are coupled respectively to the first and second ends of the first suture.
5. The catheter anchor device of claim 2 , wherein the pull handle is formed from at least one of paper or plastic.
6. The catheter anchor device of claim 1 , further comprising an adhesive element attached to the base.
