Patent ID: 7806882

Claim:
A tampon saturation monitoring system comprising: a. a tampon including: i. a fluid absorption body protruding along a saturation progress axis, said fluid absorption body including a fluid access end and a peripheral end opposite to said fluid access end in the direction of said saturation progress axis; ii. a saturation sensor extending axially with respect to said saturation progress axis in between said fluid access end and said peripheral end, said saturation sensor including at least two proximal signal terminals having a signal potential across a fluid responsive medium that is separating said at least two proximal signal terminals, said fluid responsive medium being in a wetting communication with said fluid absorption body, said fluid saturation sensor generating a gradual wetting response signal in conjunction with an axially progressing saturation boundary of said body fluid absorption element; iii. a first signal line peripherally connecting said saturation sensor across said peripheral end; b. a signal processor in a first communication with said saturation sensor via said first signal line, said signal processor monitoring the progress of said saturation boundary based on the wetting response signal; and c. a notifier in communication with said signal processor, said notifier providing notification about said saturation boundary progress in response to a signal from said signal processor.
