Patient fluid line access valve antimicrobial cap/cleaner
First Claim
1. A device for maintaining a patient fluid line access valve having an access portion with a distalmost end face that includes a septum and external threads on the access portion proximate the distalmost end face, the device comprising:
- a housing having an inner cavity, wherein an opening to the inner cavity is configured for receiving the access portion of the patient fluid tine access valve;
a material impregnated with a liquid antimicrobial agent prior to receiving the access portion of the patient fluid line access valve, wherein the material is disposed in the inner cavity;
threading protruding inwardly into the inner cavity from an inner wall of the housing near the opening, the threading configured to engage the external threads of the access portion of the patient fluid line access valve as the housing is placed over the access portion of the patient fluid line access valve to contact the material with the distalmost end face of the access portion of the patient fluid line access valve, and configured to disinfect the distalmost end face and at least a portion of the external threads of the access portion of the patient fluid line access valve with the liquid antimicrobial agent from the material,wherein the threading receives the external threads of the access portion of the access valve thereby causing the distalmost end face to advance into the inner cavity such that the septum contacts the material.

Abstract
Cap and cleaning devices antiseptically maintain patient fluid line access valves to minimize the risk of infection via catheters. The devices have a cap that may contain a dry pad impregnated with an antimicrobial agent. The cap covers the access portion of the access valve when not in use. The devices have a hood that contains a wet pad impregnated with a cleaning solution and, optionally, an antimicrobial agent. The wet pad cleans the access portion of the access valve prior to and optionally, after the access valve is utilized to access the patient fluid line.

12. A device for maintaining a patient fluid line access valve having an access portion with a distalmost end face that includes a septum and external threads on the access portion proximate the distalmost end face, the device comprising:
-
a housing for covering the access portion of the patient fluid line access valve, the housing having an open end, a closed end, and a cavity, the housing including a thread on an inner wall of the cavity proximate the open end for engaging the external threads on the access portion of the patient fluid line access valve; a material impregnated with a liquid antimicrobial agent prior to attachment of the housing to the access portion of the patient fluid line access valve, the material being positioned within the cavity for contacting the distalmost end face of the access portion of the patient fluid line access valve when the housing is positioned over and covers the access portion to reduce the amount of microbes on the access portion, wherein in response to insertion of the access portion of the patient fluid line access valve into the cavity, the thread is configured to engage the external threads on the access portion as the access portion is advanced into the inner cavity so that the distalmost end face of the access portion contacts the material to provide the liquid antimicrobial agent to the septum and at least a portion of the external threads. - View Dependent Claims (13, 14)

15. A device for maintaining a threaded patient fluid line access valve having an access portion with a distalmost end face that includes a septum and external threads on the access portion proximate the distalmost end face, the device comprising:
-
a housing having an inner cavity for covering the access portion of the patient fluid line access valve; a material within the housing and impregnated with a liquid antimicrobial agent prior to contacting the patient fluid line access valve, the material being configured to contact at least a portion of the threaded patient fluid line access valve and the distalmost end face of the patient fluid line access valve to reduce the amount of microbes on the patient fluid line access valve; a thread within the inner cavity of the housing and positioned between the material and an opening to the inner cavity, the thread for engaging the external threads of the threaded patient fluid line access valve to cause the material to contact the distalmost end face of the patient fluid line access valve, wherein in response to the distalmost end face of the access valve being inserted into the housing, the distalmost end face contacts the material to provide the liquid antimicrobial agent to the septum and at least a portion of the external threads. - View Dependent Claims (16, 17, 18)
