Absorbent articles including a body fluid signaling device

摘要

Wetness indicators may include alarm devices that are designed to assist parents or attendants in identifying a wet diaper condition early on. These devices produce either a visual or an audible signal. Many of these devices rely on electronics, which may increase the expense of the absorbent article. Further, electronic devices rely on electrical sources and may be prone to failure if not utilized for an extended period of time. The invention concerns a signaling device that does not appreciably increase the cost of the absorbent article, while providing a meaningful (e.g. visible indication of time passed since insult) signal to the caregiver without relying on an electrical source for operation.
