Abstract

Breastpump assemblies having antimicrobial agents associated therewith are disclosed. Embodiments include breastpump assemblies associated with elemental nanosilver. Other embodiments include breastpump assemblies associated with ionic silver in an ionic exchange resin.

Claims

1. An improved breastshield for a breastpump, comprising:

a breastshield, said breastshield having a first inner surface adapted to receive a breast therein and direct breastmilk therethrough, and

an antimicrobial agent applied to at least a portion of said breastshield inner surface.

2. The breastshield of claim 1 wherein said antimicrobial agent is comprised of an antimicrobial form of silver.

3. The breastshield of claim 2 wherein said antimicrobial form of silver is exposed on said breastshield inner surface.

4. The breastshield of claim 2 wherein said antimicrobial form of silver is in part partially embedded in said breastshield, and said breastshield inner surface is of a material that permits the silver to migrate to said breastshield inner surface.

5. The breastshield of claim 1 wherein said antimicrobial agent is comprised of silver sodium hydrogen zirconium phosphate.

6. The breastshield of claim 1 wherein said antimicrobial agent is a nanosilver particulate material.

7. A method of conferring antimicrobial properties to a breastpump assembly, comprising:

providing one or more of a breastshield, other breastpump related components and breast feeding equipment, said breastshield and said other breastpump related components and breast feeding equipment having surfaces which come into contact with a mother'"'"'s body or breastmilk in use, and

providing a contact active antimicrobial agent to at least portions of said one or more of a breastshield, said other breastpump related components and breast feeding equipment.

8. The method of claim 7 wherein said antimicrobial agent is comprised of an antimicrobial form of silver.

9. The method of claim 8, further comprising providing the antimicrobial form of silver in a layer on said surfaces.

10. The method of claim 9, wherein said providing of said antimicrobial form of silver is accomplished by applying a solution containing silver sodium hydrogen zirconium phosphate onto at least said breastshield inner surface.

11. The method of claim 8, wherein said one or more of a breastshield, said other breastpump related components and said breast feeding equipment is comprised of a material wherein said antimicrobial sliver is embedded for migration to an exposed surface thereof.

12. The method of claim 7, wherein said one or more of a breastshield, said other breastpump related components and breast feeding equipment includes one or more of bottles, collars, caps, lids, feeding nipples, freezer bags, cooler carriers, pump valves, separation membranes, and breastshield inserts.

13. The method of claim 7, wherein said agent includes lanolin.

14. A method of reducing microbial activity during breastpumping or breast feeding, comprising:

providing one or more of a breastshield and other breastpump or breast feeding related components with a contact active antimicrobial agent comprising silver.

15. A method of reducing microbial activity during breastpumping, comprising:

providing a lanolin composition with a contact active antimicrobial agent comprising silver to form a lanolin based antimicrobial agent; and

applying the lanolin based antimicrobial agent to one or more of a user, a breastshield and other breastpump related components.
