Abstract
A system, method, and article for delivering an antimicrobial agent into the lumen of a trans-dermal catheter are disclosed. In an embodiment, the system comprises an elongate member configured for insertion into a lumen of a catheter, and the elongate member containing an antimicrobial. In the alternative an antimicrobial agent can be placed on an interior surface of a retaining ring.
Claims28
A method of delivering antimicrobial to a catheter, the method comprising:
- filling at least a portion of the catheter with a liquid;
- using a clamp to block flow of the liquid from a proximal end to a distal end of the catheter;
- and
- inserting an elongate member into the proximal end of the catheter such that the elongate member is entirely proximal to the clamp so as to cause at least some of the liquid to flow out of a proximal opening of the catheter, wherein the elongate member includes the antimicrobial;
- wherein the elongate member is connected to a male luer connector, the male luer connector further comprises a tapered sealing member with a solid cross section.
A method of delivering an antimicrobial to a catheter containing a liquid, the method comprising:
- closing a clamp onto the catheter proximal to a distal end of the catheter to close a lumen of the catheter, thereby restricting flow of the liquid into the distal end of the catheter;
- and
- after closing the clamp, inserting an antimicrobial-containing elongate member into a proximal end of the catheter such that the antimicrobial-containing elongate member is entirely proximal to the clamp;
- wherein a male luer connector is connected to the antimicrobial-containing elongate member, the male luer connector further comprises a tapered sealing member with a solid cross section.
A method of delivering antimicrobial to a catheter, the method comprising:
- filling at least a portion of the catheter with a liquid;
- closing a clamp onto the catheter proximal to a distal end of the catheter to close a lumen of the catheter, thereby restricting flow of the liquid into the distal end of the catheter;
- after closing the clamp, inserting an elongate member into a proximal end of the catheter to cause the liquid to flow out of a proximal opening of the catheter, wherein the elongate member includes antimicrobial, wherein the antimicrobial of the elongate member transfers from the elongate member into the catheter proximal to the clamp, and the clamp prevents the transferred antimicrobial from entering the catheter distal to the clamp;
- and
- engaging an exterior surface of the catheter with an internal surface of a male luer connector, the male luer connector being connected to the elongate member, wherein the internal surface of the male luer connector includes antimicrobial, wherein the liquid that flows out of the proximal opening flows to the exterior surface of the catheter and transfers the antimicrobial of the internal surface to the exterior surface of the catheter, and wherein the elongate member is entirely proximal to the clamp during the inserting and engaging steps;
- wherein the male luer connector includes a tapered member with a solid cross section.
