<p>An absorbent pad or tampon is defined which permits a pregnant woman herself to determine with a reasonable degree of accuracy whether or not she has expelled amniotic fluid. The absorbent pad or tampon intended to be worn by the pregnant woman contains a detector or indicator chemical which produces a visual change (usually a color change) in the pad upon contact with amniotic fluid which is leaked or otherwise discharged from the amnion. The woman wearing the device can observe the visual change and know with a reasonable degree of certainty whether or not the discharged fluid was amniotic fluid, and thus know whether to contact her medical advisor. Preferably the chemical indicator is a dye, and more preferably nitrazine or a related chemical. Further, from this invention, permitting immediate detection of discharged amniotic fluid by the woman herself, a physician can determine the imminence of a pregnant woman's delivery of her infant or detect the potential for there to be a fetal abnormality or other dysfunctional pregnancy.</p> |
