Medical and hygiene products with removable portions for testing absorbed fluid
One embodiment of the present invention provides an apparatus for analyzing substances included in a liquid. The apparatus includes an absorber for absorbing the liquid and a testing device separate from the absorber. The absorber includes a main body and a detachable strip embedded in the main body, and both the main body and the detachable strip absorb the liquid. The testing device includes one or more sensors positioned on a top surface of the testing device to provide information associated with the substances included in the liquid in response to the detachable strip being placed on the top surface of the testing device.
1. An apparatus for analyzing substances included in a liquid, comprising:
an absorber comprising front and back surfaces for absorbing the liquid, wherein the liquid flows from the front surface to the back surface, wherein the back surface comprises a recess sealed by a detachable strip embedded in a main body of the absorber, wherein the detachable strip is configured to absorb the liquid from the main body, and wherein the detachable strip is configured to be peeled away from the back surface of the absorber in response to a testing need, thereby facilitating removal of the detachable strip without contamination; and
a testing device separate from the absorber, wherein the testing device comprises one or more sensors positioned on a top surface of the testing device to provide information associated with the substances included in the liquid in response to the detachable strip being peeled away from the back surface of the absorber and placed on the top surface of the testing device.
2. The apparatus of claim 1 , wherein the sensors include one or more of:
a capacitance sensor;
a conductance sensor;
a chemical sensor; and
a biological sensor.
3. The apparatus of claim 2 , wherein the biological sensor includes a printable carbon-nanotube based sensor.
4. The apparatus of claim 1 , wherein the detachable strip comprises one or more additional sensors.
5. The apparatus of claim 1 , wherein the sensors are configured to detect one or more of:
a biological substance; and
a chemical substance.
6. The apparatus of claim 1 , wherein the testing device comprises a microprocessor configured to process outputs of the sensors.
7. The apparatus of claim 6 , wherein the testing device further comprises a wireless communication module configured to communicate the processed outputs to an external computing device.
8. The apparatus of claim 1 , wherein the testing device further comprises a display configured to display outputs of the sensors.
9. The apparatus of claim 1 , wherein the absorber is part of:
a sanitary pad;
a diaper; or
a wound dressing.
10. The apparatus of claim 1 , wherein the detachable strip includes a tab extending out of a back surface of the absorber to allow a user to remove the detachable strip from the back surface of the absorber.
11. A method for analyzing substances included in a liquid, the method comprising:
applying an absorber comprising front and back surfaces to absorb the liquid, wherein the liquid flows from the front surface to the back surface, wherein the back surface comprises a recess sealed by a detachable strip embedded in a main body of the absorber, wherein the detachable strip is configured to absorb the liquid from the main body, and wherein the detachable strip is configured to be peeled away from the back surface of the absorber in response to a testing need, thereby facilitating removal of the detachable strip without contamination;
peeling away the detachable strip from the main body of the absorber; and
placing the detachable strip on a top surface of a testing device separate from the absorber, wherein the testing device comprises one or more sensors configured to provide information associated with the substances included in the liquid.
12. The method of claim 11 , wherein the sensors include one or more of:
a capacitance sensor;
a conductance sensor;
a chemical sensor; and
a biological sensor.
13. The method of claim 12 , wherein the biological sensor includes a printable carbon-nanotube based sensor.
14. The method of claim 11 , wherein the detachable strip comprises one or more additional sensors.
15. The method of claim 11 , further comprising processing, by a microprocessor located on the testing device, outputs of the sensors.
16. The method of claim 15 , further comprising transmitting, by a wireless communication module located on the testing device to an external computing device, processed outputs of the sensors.
17. The method of claim 11 , further comprising displaying, by a display located on the testing device, outputs of the sensors.
18. The method of claim 11 , wherein removing the detachable strip from the main body of the absorber involves pulling a tab extending out of a back surface of the absorber.
19. The method of claim 18 , wherein the absorber is part of:
a sanitary pad;
a diaper; or
a wound dressing.
20. An apparatus for analyzing substances included in menstrual fluid of a user, comprising:
a feminine hygiene product (FHP) for absorbing the menstrual fluid, wherein the FHP includes front and back surface, wherein the liquid flows from the front surface to the back surface, wherein the back surface comprises a recess sealed by a detachable strip embedded in a main absorbing body of the FHP, wherein the detachable strip is configured to absorb the menstrual liquid from the main absorbing body, and wherein the detachable strip is configured to be peeled away from the back surface of the absorber in response to a testing need, thereby facilitating removal of the detachable strip without contamination; and
a testing device separate from the FHP, wherein the testing device comprises one or more sensors positioned on a top surface of the testing device to provide information associated with the substances included in the menstrual fluid in response to the detachable strip being peeled away from the back surface of the FHP and placed on the top surface of the testing device.
