Claims24
A method, comprising:
- forming an antimicrobial blend including a quantity of an antimicrobial additive combined with a quantity of polymer;
- and
- forming a medical device with the antimicrobial blend, wherein a surface of the medical device exhibits antimicrobial properties.
A medical device, comprising:
- an antimicrobial structure comprising a mixture of:
- a polymer;
- and
- an antimicrobial additive comprising at least one of silver phosphate glass oxide or copper oxide, silver, silver oxide, copper, or copper phosphate glass oxide;
- wherein a surface of the antimicrobial structure exhibits antimicrobial properties.
2 more elements
A medical device, comprising:
- an antimicrobial structure comprising a mixture of:
- polyethylene, polypropylene, polycarbonate, or silicone;
- and
- an antimicrobial additive comprising silver phosphate glass oxide or copper oxide;
- wherein a percentage-by-weight of the silver phosphate glass oxide relative to the polymer is in the range of 2.5% to 10%;
- and
- wherein a surface of the antimicrobial structure provides at least 99.85% reduction (log 2 efficacy) of E. coli bacteria and at least 99.99% reduction (log 4 efficacy) of S. aureus bacteria.
