1. A system for monitoring hand hygiene compliance comprising:
- a catheter assembly associated with one or more tubes for conveying fluids;
a charge transfer proximity sensor assembly comprising an electrode coupled to the catheter assembly; and
a charge transfer controller circuit electrically connected to the electrode, the charge transfer proximity sensor assembly being configured to detect contact or close proximity by a person with the catheter assembly and generate an electrical signal for controlling an annunciator responsive to such contact; and
a hand sanitizer electrically associated with the controller configured for generating a signal evidencing use of such sanitizer.

Abstract
One or more intravenous catheter assemblies are monitored to ensure compliance with required hygienic procedures and/or to ensure only persons who have properly sanitized their hands are allowed to attend to such catheter assemblies. Detecting electrodes incorporated as part of such catheter assemblies facilitate determination as to whether potential contamination may have occurred. The hygienic status of a health care worker attending to the catheter assembly, as possibly evidenced by detected use of a sanitizer, may be used to determine whether the catheter assembly is being subjected to contamination.

7. A system comprising:
-
a catheter assembly including one or more tubes for conveying fluid and in fluid communication with a liquid source associated with a first person; a controller electrically coupled to the catheter assembly, the controller being configured to detect a change in an electrical parameter resulting from a second person'"'"'s contact with or close proximity to the catheter assembly and generate a signal upon detection of the change in the electrical parameter; and a hand sanitizer operatively associated with the controller configured for generating a signal evidencing use of the hand sanitizer. - View Dependent Claims (8, 9, 10)
