Abstract: A method and apparatus for predicting the fertility status of a human female subject. The onset of menstruation of the subject is noted. Daily determinations are made of the subjects eccrine sweat pH, beginning not more than 4 days following menstruation. The start of the fertile period is determined as a function of a significant decline in pH, followed by a sharp rise. The peak of this pH rise is indicative of imminent ovulation, which generally coincides with a second pH decline of variable degree. The apparatus provides provisions for automatically taking the pH readings, analysing them, and displaying to the user the daily fertility status.

Abstract: A method and device to predict ovulation in a female human by measuring changes in the concentration of a number of ions in eccrine sweat is disclosed. The concentration, or changes in concentration, of one or more ions are determined throughout the day and analyzed against predetermined patterns in order to predict ovulation one to five days in advance. This permits the user to more accurately determine commencement of the fertile phase, which for female humans is generally considered to be about four days prior to ovulation to one day after ovulation. The concentration of the ions measured include sodium (Na+), potassium (K+), ammonium (NH 4 +), calcium (Ca 2 +), chloride (Cl-) and nitrate (NO 3 -). To further increase the accuracy of the reading, a large number of readings can be obtained throughout a day and statistically analyzed to determine the change over time. In addition, the concentration of two or more ions can be obtained to increase accuracy. Ratiometric measurements between two or more ions can be determined to increase accuracy and account for ion accumulation on the skin. Ratiometric measurements between ammonium (NH 4 +) and calcium (Ca 2 +) have been found to provide more distinct patterns because the concentration of these two ions change in opposite directions during the relevant period preceding ovulation.
Abstract translation: 公开了一种通过测量异常汗液中多个离子的浓度变化来预测女性人体排卵的方法和装置。 在一天内确定一个或多个离子的浓度或浓度变化，并针对预定模式进行分析，以提前一到五天预测排卵。 这允许用户更准确地确定可育阶段的开始，对于女性人类，通常认为排卵前约四天至排卵后一天。 测得的离子浓度包括钠（Na +），钾（K +），铵（NH4 +），钙（Ca2 +），氯化物（Cl-）和硝酸盐（NO3-）。 为了进一步提高读数的准确性，可以在一天内获得大量读数，并进行统计分析以确定随时间的变化。 此外，可以获得两个或更多个离子的浓度以提高精度。 可以确定两个或更多个离子之间的比例测量，以提高准确度并解释皮肤上的离子积聚。 已经发现铵（NH4 +）和钙（Ca2 +）之间的比例测量提供更多不同的模式，因为在排卵之前的相关时期，这两种离子的浓度在相反方向变化。

Abstract: Un método y aparato para producir el estado de fertilidad de una mujer. Se observa el inicio de la menstruacion de la persona. Se realizan determinaciones diarias del pH del sudor ecrino de las personas, empezando no más de 4 días después de la menstruacion. El inicio del período fértil se determina como funcion de una reduccion significante en le pH seguido por un aumento abrupto. El pico de este aumento de pH indica la ovulacion inminente, que generalmente coincide con una segunda reduccion de pH de grado variable. El aparato provee condiciones para tomar automáticamente las lecturas de pH, analizarlas, y mostrar al usuario el estado de fertilidad diario.
