DETAILED DESCRIPTION

[0030] Before describing the invention in detail, it should be observed that the present invention resides primarily in a novel and non-obvious combination of elements and process steps. So as not to obscure the disclosure with details that will readily be apparent to those skilled in the art, certain conventional elements and steps have been presented with lesser detail, while the drawings and specification describe in greater detail other elements and steps pertinent to understanding the invention.

[0031] The following embodiments are not intended to define limits as to the structure or method of the invention, but only to provide exemplary constructions. The embodiments are permissive rather than mandatory and illustrative rather than exhaustive.

[0032] In the following, we describe the structure of an embodiment of a training pad 110a, 110b for absorbing and diagnosing illness in juvenile human and dog urine with reference to FIG. 1A, in such manner that like reference numerals refer to like components throughout; a convention that we shall employ for the remainder of this specification.

[0033] In an embodiment, as shown in FIGS. 1A and 1B, a training pad system 100a, 100b can include: [0034] a) a training pad 110a, 110b, which is configured to receive (i.e., absorb) a liquid, such as urine, when the training pad is positioned on an underlying surface 170, such as a floor in a bathroom or other room of a house; or on a seat of a chair, such as a wheel chair, or car sear; or a on a mattress of a bed, or on another surface used by humans or pets; [0035] such that the training pad 110a, 110b can be used for house training of a pet 182, such as a dog 182, or a human 184, including a juvenile human, an elderly human, or a human patient with a medical condition.

[0036] In a related embodiment, as shown in FIGS. 1A and 2A, the training pad 110a, 110b can further include at least one diagnostic zone 120, which can further include: [0037] a) at least one diagnostic test area 122, which can be configured to indicate a diagnostic condition, after the at least one diagnostic test area 122 is exposed to urine 240 (i.e., saturated with urine), such that a color change visually indicates a potential disease condition; [0038] wherein the at least one diagnostic zone 120 can be located on an upper surface 310 of the training pad 110a, 110b and is configured to visually indicate illness through coloration.

[0039] In a further related embodiment, the at least one diagnostic zone 120 can be indicated with a first printed line (or alternatively a first printed surface area) on a top surface of the training pad 110a, 110b, wherein the first printed line indicates an outer edge of the at least one diagnostic zone 120, and wherein the first printed line for example can be a colored line (or colored surface area), which indicates a location of the diagnostic test areas(s) 122.

[0040] In a yet further related embodiment, the at least one diagnostic test area 122 can be indicated with a second printed line (or alternatively a second printed surface area) on a top surface of the training pad 110a, 110b, within the at least one diagnostic zone 120, wherein the second printed line indicates an outer edge of the at least one diagnostic zone 120, and wherein the second printed line for example can be a colored line (or colored surface area), which indicates a location of the diagnostic test areas(s) 122.

[0041] In a related embodiment, as shown in FIG. 1A, the training pad 110a can be sized appropriately for domestic pet use, for example with a rounded rectangular shape as shown.

[0042] In a further related embodiment, the at least one diagnostic test area 122 can be configured (by predetermined calibration) with a calibrated concentration of the reactive agent 123 of the at least one diagnostic test area 122, such that the concentration of the reactive agent 123 is calibrated for exposure of the urine 240 until drying of the urine 240 has completed, such that exposure of urine 240 with a negative diagnostic condition will result in a color intensity up to or less than a negative threshold signal 446, and exposure of urine 240 with a positive diagnostic condition will result in a color intensity of at least or more than a positive threshold signal 448, wherein the positive threshold signal 448 is more color intense (i.e., has a stronger color) than the negative threshold signal 446. Note that conventional multi-panel test strips are typically calibrated for limited time exposure, such as 20 or 30 seconds, which generally permits more accurate reading and can distinguish an increased number of test value readings (rather than just negative or positive). The reduced accuracy of testing with increased length exposure (i.e. until completion of drying) means that the tests can normally be considered as only indicating a risk of disease, which warrants more accurate diagnostic testing to permit an actual diagnosis.

[0043] In another related embodiment, as shown in FIG. 1B, at least a portion of a training pad 110b can be configured to match a shape of a lower portion 192 of a toilet 190, such that the training pad covers a surface area surrounding the lower portion of the toilet, when the training pad 110b is positioned around the toilet 190, wherein the training pad 110b can further include: [0044] a) a pad cutout 212, as shown in FIG. 2B, which is configured to (i.e. shaped to) match a shape of the lower portion 192 of a toilet 190, such that the training pad 110b covers a surface area surrounding front, left, and right sides of the lower portion 192 of the toilet 190, when the pad cutout 212 of the training pad 110b is positioned around the lower portion 192 of the toilet 190.
