Abstract
An apparatus and method are provided for visually monitoring, detecting, and/or determining the presence, absence, and/or growth of harmful or potentially harmful bacterial microorganisms beneath a wound dressing, in one example used to cover an indwelling central venous catheter or other catheter. A bacteria detection apparatus includes a barrier membrane, a permeable membrane for placement proximate a wound or a catheter insertion site, and an indicator between the barrier membrane and the permeable membrane for indicating the presence of bacteria proximate the permeable membrane. A method of using a bacterial growth detection apparatus is also provided.

1-30. (canceled)
A method of indicating microbial growth at a wound site, said method comprising the steps of:
- I) providing a wound dressing, which comprises:
- a) a barrier membrane,
- b) a permeable membrane for placement proximate to a wound, and
- c) an indicator which visibly signals microbial growth at the wound site;
- II) placing the permeable membrane of the wound dressing over the wound;
- and
- III) detecting the presence of microbial growth by detecting a visible change in the indicator, wherein the visible change in the indicator is caused by byproducts of microbial growth at the wound site.
