Abstract
The present disclosure is directed to a device for delivering an antimicrobial composition into a medical device. Some embodiments disclosed herein provide a method for preventing infection and microbial ingress in medical device connections. The device includes a male connector with a distal tip and a recess at the distal tip. The surface of the recess includes an antimicrobial composition. In certain implementations a male luer comprises a tapered sealing member further comprising a recess containing chlorhexidine acetate.
Claims20
A male connector device for coupling with a female connector, the male connector device comprising:
- a male luer comprising a male tapered surface extending axially away from a wall of the male connector device;
- a shroud extending axially away from the wall of the male connector device, the shroud configured to surround at least a portion of a length of the male luer;
- an inner thread of the shroud configured to engage with corresponding threads of the female connector;
- a fluid flow channel through the male connector device;
- a plurality of recesses formed in a distal portion of the male luer, each recess of the plurality of recesses extends proximally from a distal end of the male luer, wherein the plurality of recesses are configured to create a space between a surface of each of the plurality of recesses and a female tapered surface of the female connector that can receive a liquid when the male connector device is coupled with the female connector;
- and
- a water-soluble antimicrobial composition positioned on the surface of each of the plurality of recesses.
A connector device for delivering an antimicrobial composition into a medical device, the connector device comprising:
- a male connector comprising a male tapered surface configured to engage a female connector of the medical device, the female connector having a female tapered surface, such that the male tapered surface engages the female tapered surface to form a fluid-tight seal, the male connector further comprising:
- a conical taper defined in part by the male tapered surface;
- a distal tip having a distal end;
- a plurality of recesses each comprising a recess surface, each recess of the plurality of recesses extends proximally from the distal end of the male connector, the recess surface of each of the plurality of recesses are configured to extend radially inward of the male tapered surface;
- a fluid flow channel through the male connector;
- and
- a water-soluble antimicrobial composition positioned on the recess surface of the plurality of recesses;
- wherein:
- the connector device is configured such that, upon insertion of the male connector into the female connector, at least one cavity is formed between the recess surface of the plurality of recesses and the female tapered surface of the female connector.
