Abstract
Systems, methods, and devices for providing an antimicrobial composition to the proximal elements of a transdermal catheter and into the lumen of the transdermal catheter are disclosed. In an embodiment, the device includes a cap configured to be removably secured to the hub, the cap comprising a ring member comprising first threads for engaging second threads on the hub of the transdermal catheter, the ring member having an opening through its interior; and an insert member secured within the opening of the ring member; wherein the insert member comprises an antimicrobial composition and the ring and insert member do not readily rotate with regard to one another.
Claims21
A connector configured to be removably secured to a hub on a proximal end of a transdermal catheter, the connector comprising:
- a ring member, comprising:
- first threads configured to engage second threads on the hub of the transdermal catheter;
- an opening through an interior of the ring member;
- two or more retaining fingers projecting into the opening;
- and
- one or more recesses positioned between the two or more retaining fingers;
- and
- an insert member positioned within the opening of the ring member, comprising:
- a central protrusion extending axially along at least a portion of the insert member;
- and
- one or more fins projecting away from an outside surface of the insert member and extending axially from a proximal end of the insert member, the one or more fins engaged with the one or more recesses to prevent rotational and axial movement of the insert member relative to the ring member;
- wherein:
- the connector comprises an antimicrobial composition on at least a portion of the insert member;
- and
- the connector is configured to provide flow within the transdermal catheter.
A connector configured to be removably secured to a hub on a proximal end of a transdermal catheter, the connector comprising:
- a ring member, comprising:
- first threads configured to engage second threads on the hub of the transdermal catheter;
- an opening through an interior of the ring member;
- and
- one or more recesses formed in the ring member;
- and
- an insert member positioned at least partially within the opening of the ring member, comprising:
- a central protrusion extending axially along at least a portion of the insert member;
- a distally extending member extending axially from a distal end of the central protrusion;
- and
- one or more fins projecting away from an outside surface of the central protrusion and positioned at a proximal end of the central protrusion, the one or more fins each engaged with the one or more recesses to prevent rotational movement of the insert member relative to the ring member;
- wherein the connector comprises an antimicrobial composition on at least a portion of an inside surface of the ring member.
A device for insertion into a hub on a proximal end of a transdermal catheter, the device comprising:
- a connector configured to be removably secured to the hub, the connector comprising:
- a ring member, comprising:
- first threads configured to engage second threads on the hub of the transdermal catheter;
- and
- an opening through an interior of the ring member;
- and
- an insert member positioned within the opening of the ring member, comprising:
- a central protrusion extending axially along at least a portion of the insert member;
- and
- one or more fins projecting away from an outside surface of the central protrusion, the one or more fins having a radius measured from a center of the insert member and an arcuate distance measured around a base of the one or more fins, the radius and the arcuate distance are configured such that the one or more fins are secured to the ring member achieve to an interference fit in order to rotationally lock the ring member to the insert member at least when the device is rotated and threaded onto the hub at the proximal end of the transdermal catheter;
- wherein the insert member comprises an antimicrobial composition on at least a portion of the insert member.
