Abstract

Illustrative pairs of caps are disclosed, each of the caps being sized and shaped to provide a protective union about a separated medical connector. A pair of caps can include a male cap and a female cap, each of which is configured to be coupled to the other cap in an assembly. The assembly is sealed until the caps are separated for use, thereby maintaining sterility of the internal surfaces of the caps. Related methods are also disclosed.

Claims (28)

1. A method of applying an antiseptic agent to a medical connection having a male luer connector and a needleless injection site, the method comprising:

providing an assembly comprising

a male-disinfecting cap including a receiving portion having (i) a single opening in which a male luer connector can be received, (ii) an exterior surface having a recess disposed about an outer circumference thereof and (iii) an antiseptic agent;

a female-disinfecting cap including a receiving portion having (i) a single opening in which a needleless injection site can be received, (ii) an exterior surface having a recess disposed about an outer circumference thereof, and (iii) an antiseptic agent; and

a seal disposed around and in contact with both the recess of the exterior surface of the male-disinfecting cap and the recess of the exterior surface of the female-disinfecting cap and linking the male-disinfecting cap to the female-disinfecting cap;

separating the male-disinfecting cap from the assembly;

inserting the male luer connector into the receiving portion of the male-disinfecting cap so as to transfer at least some of the antiseptic agent to at least a surface of the male luer connector;

separating the female-disinfecting cap from the assembly; and

inserting the needleless injection site into the receiving portion of the female-disinfecting cap so as to transfer at least some of the antiseptic agent to at least a surface of the needleless injection site.

2. The method of claim 1 , wherein the assembly further comprises a pad.

3. The method of claim 2 , wherein the pad is disposed within the receiving portion of the male-disinfecting cap.

4. The method of claim 3 , further comprising scrubbing the male luer connector with the pad.

5. The method of claim 1 , wherein separating one cap from the assembly comprises rotating the male-disinfecting cap relative to the female-disinfecting cap.

6. The method of claim 1 , wherein the male-disinfecting cap comprises threading, the method further comprising engaging the threading of the male-disinfecting cap into the threading of the male luer connector.

7. A method of applying an antiseptic agent to a medical connection having a male luer connector and a needleless injection site, the method comprising:

providing an assembly comprising

a male-disinfecting cap having an interior portion with a single opening and an exterior surface having a recess disposed about an outer circumference thereof;

a first pad having an antiseptic agent and disposed within the interior portion of the male-disinfecting cap;

a female-disinfecting cap having an interior portion with a single opening and an exterior surface having a recess disposed about an outer circumference thereof;

a second pad having an antiseptic agent and disposed within the interior portion of the female-disinfecting cap; and

a seal disposed around and in contact with both the recess of the male-disinfecting cap and the recess exterior of the female-disinfecting cap and linking the male-disinfecting cap and female-disinfecting cap;

separating the male-disinfecting cap from the assembly;

inserting the male luer connector into the interior portion of the male-disinfecting cap so as to transfer at least some of the antiseptic agent of the first pad to at least a surface of the male luer connector;

separating the female-disinfecting cap from the assembly; and

inserting a needleless injection site into the interior portion of the female-disinfecting cap so as to transfer at least some of the antiseptic agent of the second pad to at least a surface of the needleless injection site.

8. The method of claim 7 , wherein in the assembly, a portion of the male-disinfecting cap is nested within the female-disinfecting cap.

9. The method of claim 7 , further comprising scrubbing the needleless injection site with the second pad.

10. The method of claim 7 , wherein the male-disinfecting cap comprises threading, the method further comprising engaging the threading into threading of the male luer connector.
