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.

Claims

1. A cap device for reducing risk of contamination of a patient fluid line access valve, the cap device comprising:

a first cavity for retaining a first pad, the first pad comprising a first cleaning solution, the first cavity further comprising a set of threads for threadedly receiving a set of threads of the patient fluid line access valve such that an access portion of the patient fluid access valve contacts the first pad;

a second cavity for retaining a second pad comprising a second cleaning solution, the second cavity having an opening through which the access portion of the patient fluid access valve may be inserted to temporarily contact the second pad; and

an internal wall interposed between the first and second cavities.

2. The cap device of claim 1 wherein the first and second cleaning solutions comprise an antimicrobial agent.

3. The cap device of claim 2 wherein the first cleaning solution is different than the second cleaning solution.

4. The cap device of claim 1 wherein the internal wall comprises a breakable connector.

5. The cap device of claim 1 and further comprising:

a lid sealing the second pad within the second cavity.

6. The cap device of claim 1 further comprising a housing in which the first and second cavities are provided.

7. A method of reducing risk of contamination of a patient fluid line access valve, the method comprising:

inserting an access portion of the patient fluid line access valve into a first cavity of a cap device, the first cavity having a first pad comprising a first cleaning solution, the first cavity having an opening through which an access portion of the patient fluid access valve may be inserted to temporarily contact the first pad; and

attaching a second cavity of the cap device to the access portion of the patient fluid line access valve, the second cavity having a second pad comprising a second cleaning solution, the second cavity further comprising a set of threads for threadedly receiving a set of threads of the patient fluid line access valve such that the access portion of the patient fluid access valve contacts the second pad, the cap device further comprising an internal wall separating the first and second cavities.

8. The method of claim 7 and further comprising:

removing the access portion of the patient fluid access valve from the first cavity prior to attaching the second cavity of the cap device to the access portion of the patient fluid line access valve.

9. The method of claim 7, wherein the first cleaning solution is different than the second cleaning solution.

10. The method of claim 7 and further comprising:

removing a lid from at least one of the first and second cavities prior to inserting or attaching the access portion of the patient fluid line access valve to the respective cavity.

11. The method of claim 7, wherein the cleaning solutions of the first and second pads comprise an antimicrobial agent.
