Abstract
The present disclosure is directed to a device for delivering an antimicrobial composition into an infusion device. The disclosure provides 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.
Claims36
A device for delivering an antimicrobial composition into an infusion device, the device comprising:
- a male connector having a male tapered surface, the male connector comprising:
- a fluid flow channel through the male connector;
- a distal tip having a distal end;
- an annular recess extending proximally from the distal end of the distal tip, the recess having an annular recess surface, wherein the recess surface is radially inward of a line of taper extending along the male tapered surface at a first taper angle relative to a central longitudinal axis of the male connector;
- and
- a water-soluble antimicrobial composition positioned on the recess surface;
- wherein the device is configured for delivering an antimicrobial composition into an infusion device.
A device for delivering an antimicrobial composition into an infusion device, the device comprising:
- a male connector comprising a male tapered surface configured to engage a female connector of the infusion 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;
- an annular recess comprising an annular recess surface extending proximally from the distal end, the recess surface positioned radially inward of a line of taper extending along the male tapered surface;
- a tapered surface distal edge proximal to the distal tip, the tapered surface distal edge having an outer diameter greater than the outer diameter of the distal tip;
- a fluid flow channel through the male connector;
- and
- a water-soluble antimicrobial composition positioned on the recess surface;
- wherein:
- upon insertion of the male connector into the female connector, an annular cavity is formed between the recess surface and the female tapered surface of the female connector;
- and
- the device is configured for delivering an antimicrobial composition into an infusion device.
A device for delivering an antimicrobial composition into an infusion device, the device comprising:
- a male connector having a male tapered surface configured to insert into a female connector of an infusion 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 having:
- a conical taper defined in part by the male tapered surface;
- a distal tip having an outer diameter that is 50 percent to 95 percent of an inner diameter of the female tapered surface at a point radially outward of the distal tip;
- an annular recess surface proximal to the distal tip and inside the conical taper;
- a fluid flow channel through the male connector;
- a water-soluble antimicrobial composition positioned on the recess surface;
- wherein, upon insertion of the male connector into the female connector, an annular cavity is formed between the recess surface and the female tapered surface of the female connector, the annular cavity having a proximal end and a distal end, a volume between the proximal end and the distal end, a width measured radially, and a length measured axially;
- wherein the male tapered surface has a distal edge that at least partially defines the proximal end of the annular cavity, the distal end of the annular cavity being configured to be in fluid communication with a fluid lumen of the infusion device when inserted into the infusion device;
- and
- wherein:
- when the distal end of the annular cavity is inserted into the infusion device a fluid inside the infusion device at least partially fills the annular cavity, and at least a portion of the antimicrobial composition is dispersed within the fluid in the annular cavity;
- wherein the device is configured for delivering an antimicrobial composition into an infusion device.
