Abstract

A diagnostic sheet for use in conjunction with a disposable absorbent garment is disclosed. The diagnostic sheet may be operable to wick fluid vertically, and includes one or more diagnostic elements and a radio frequency identification device (RFID). The one or more diagnostic elements may be integrated with the diagnostic sheet and positioned at a first region of the diagnostic sheet, and the RFID may be integrated with the diagnostic sheet and positioned proximate the first region. In the presence of the fluid, each of the one or more diagnostic elements may be configured to indicate a result of a particular diagnostic test. In the presence of the fluid, the RFID may be configured to provide an indication that the fluid wicked by the diagnostic sheet has reached the one or more diagnostic elements.

a radio frequency identification device (RFID) integrated with the diagnostic sheet and positioned proximate the first region of the diagnostic sheet, wherein the RFID includes;

an antenna configured to receive and transmit signals;

signal generation circuitry configured to generate a signal for transmission by the antenna based on a wireless signal received at the antenna from an interrogator device;

power generation circuitry configured to provide operational power to the signal generation circuitry based on the wireless signal received at the antenna from the interrogator device; and

power control circuitry configured to disable the provisioning of power, by the power generation circuitry, to at least the signal generation circuitry until at least a portion of the power control circuitry is in the presence of the fluid,

wherein, in the presence of the fluid wicked to one or more diagnostic elements by the diagnostic sheet, each of the one or more diagnostic elements is configured to indicate a result of a particular diagnostic test, and

wherein the signal generated by the signal generation circuitry is configured to provide an indication to the interrogator device that the fluid has been wicked to the one or more diagnostic elements by the diagnostic sheet, the indication configured to cause the interrogator device, in response to receiving the signal, to generate a notification that indicates the fluid has been wicked to the one or more diagnostic elements by the diagnostic sheet.

2. The article of claim 1, wherein each of the one or more diagnostic elements is selected from the list consisting of:

a pH test, a specific gravity test, a protein test, a blood test, a glucose test, a ketone test, a bilirubin test, a urobilinogen test, a nitrites test, and a leukocytes test.

3. The article of claim 1, wherein the article is integrated into a disposable absorbent garment as a top sheet.

4. The article of claim 1, wherein the diagnostic sheet includes a front edge, wherein first region is proximate a front edge of the diagnostic sheet, and wherein the RFID is positioned between the one or more diagnostic elements and the front edge of the diagnostic sheet.

5. A disposable absorbent garment comprising:

a backsheet;

an absorbent core; and

a top sheet configured to wick fluid, the top sheet including;

one or more diagnostic elements integrated with the top sheet and positioned at a first region of the top sheet, wherein each of the one or more diagnostic elements is configured to, in the presence of the fluid wicked to one or more diagnostic elements by the top sheet, indicate a result of a particular diagnostic test; and

a radio frequency identification device (RFID) integrated with the top sheet and positioned proximate the first region of the top sheet, wherein, in the presence of the fluid wicked to the RFID by the top sheet, the RFID is configured to provide an indication that the fluid wicked by the top sheet has reached the one or more diagnostic element, and wherein the RFID includes;

an antenna; and

circuitry configured to;

power the RFID device in response to receiving a wireless signal from an interrogator device at the antenna,

generate a signal based on the received signal, and

provide the signal to the antenna for transmission,

wherein the circuitry is configured to cease providing power to the RFID device and to cease providing the signal when the wireless signal is received from the interrogator device and at least a portion of the circuitry is in the presence of the fluid wicked to the RFID by the top sheet, and

wherein the indication is provided by ceasing transmission of the signal, and

wherein the indication is configured to, when detected by an interrogator device, cause the interrogator device to generate a notification that indicates the fluid has been wicked to the one or more diagnostic elements by the top sheet; and

an intermediate top sheet disposed between the top sheet and the absorbent core;

wherein the absorbent core is disposed between the backsheet and the intermediate top sheet.

6. The disposable absorbent garment of claim 5, wherein each of the one or more diagnostic elements is selected from the list consisting of:

a pH test, a specific gravity test, a protein test, a blood test, a glucose test, a ketone test, a bilirubin test, a urobilinogen test, a nitrites test, and a leukocytes test.

7. The disposable absorbent garment of claim 5, wherein the top sheet that includes the one or more diagnostic elements and the RFID, and wherein the top sheet is removable.
