  • Publication number: 20200139104
    Abstract: The disclosure provides a method for preventing infection and microbial ingress in medical device connections between tubing sets and medical devices. The tubing set includes a male connector with a distal tip and a recess at the distal tip configured to trap bacterial, and deliver and confine antimicrobial into solution within a cavity formed by the recess. 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.

  • Publication number: 20200139101
    Abstract: Examples herein provide a syringe comprising a fluid reservoir and a male connector comprising a fluid flow channel in fluid communication with the fluid reservoir. The male connector including a male luer having a tapered sealing surface configured to mate with a female tapered surface of a female connector to form a substantially fluid-tight seal. The male luer has a distal tip with a recess defined by a recess surface that is distal to the tapered sealing surface. A water-soluble antimicrobial composition is disposed on the recess surface. The male luer is configured such that, when the male connector is mated with a female connector to form a substantially fluid-tight seal, a cavity is formed between the female tapered surface and the recess surface.

  • Publication number: 20200139103
    Abstract: A needleless connector and methods for preventing microbial ingress in medical device connections are disclosed. Various examples provide a needleless connector including a male luer having a recessed distal tip surface containing a water-soluble antimicrobial composition. Further examples include a trap for retaining antimicrobial composition. As the needleless connector is inserted into a female connector, a tapered surface distal edge acts to push microorganisms, while the distal tip surface is configured to leave microorganisms undisturbed. After insertion of the needleless connector, microorganisms present on the female luer surface are biased to reside in the recess region. The recess, trap, and antimicrobial composition are configured to facilitate a long-lasting supply of antimicrobial solution within the fluid-filled recess, at the same time confining the antimicrobial solution inside the recess.
