Abstract: An intravenous cannula cap (100) includes a cap body (102) formed from a medical-grade polymer and a passive contamination indicator (104) embedded within the cap body (102). The passive contamination indicator (104) includes a pH-sensitive dye micro-layer configured to undergo a color change in response to environmental exposure conditions. A semi-permeable membrane (106) is disposed adjacent to the pH-sensitive dye micro-layer and configured to permit controlled interaction between the pH-sensitive dye micro-layer and an external environment. A connection portion (110) is configured to engage with a catheter hub of an intravenous cannula. The passive contamination indicator (104) transitions from a first color state indicating sterile conditions to a second color state indicating an alert condition upon exposure to air beyond a predetermined duration, and to a third color state indicating an unsafe condition upon exposure to elevated contamination risk conditions.
