1. A tampon saturation sensor comprising:
- a. a protrusion shape including a protrusion cross section and a protrusion length, said protrusion shape protruding inside a fluid absorbing body of a tampon;
b. a first fluid accessible sensor terminal extending inside said protrusion cross section and along said protrusion length;
c. a second fluid accessible sensor terminal extending inside said protrusion cross section, along said protrusion length and adjacent said first terminal;
d. a spacer extending inside said protrusion cross section, along said protrusion length and at least in between said first terminal and said second terminal; and
wherein at least one of said fluid accessible sensor terminals and said spacer is body fluid accessible while said tampon saturation sensor is inside said fluid absorbing body.

Abstract
A tampon has a combined fluid saturation sensor and signal cable that peripherally connects the sensor with a remote signal processor. The sensor provides a blood wetting response signal to a progressing blood saturation boundary in the tampon. Cable and sensor are preferably monolithically fabricated. The lengthy sensor extends spatially inside the tampon to respond to axially progressing blood saturation as well as peripheral leakage blood flow.

20. A tampon comprising:
-
a. 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; b. a tampon saturation sensor comprising; i. a protrusion shape including a protrusion cross section and a protrusion length, said protrusion shape protruding inside said fluid absorbing body; ii. a first fluid accessible sensor terminal extending inside said protrusion cross section and along said protrusion length; iii. a second fluid accessible sensor terminal extending inside said protrusion cross section, along said protrusion length and adjacent said first terminal; iv. a spacer extending inside said protrusion cross section, along said protrusion length and at least in between said first terminal and said second terminal; wherein at least one of said both terminals and said spacer is body fluid accessible via said fluid absorbing body; c. a signal transmitting cable peripherally connecting said saturation sensor across said peripheral end; and wherein said protrusion shape is flexible inside said fluid absorbing body. - View Dependent Claims (21, 22, 23, 24, 25)
