Abstract

A multiplexed testing strip testing device includes a hydrophobic paper-based strip housing element configured for placement of one or more testing strips. One or more alignment markers on the hydrophobic paper-based housing element are marked to facilitate placement of the one or more testing strips. A cover element is arranged above the strip housing element and includes a machine-readable test identifier on an upper surface. A removably attached filtering element is arranged on the hydrophobic paper-based strip housing element.

Claims (44)

1. A multiplexed chemical testing strip device, comprising:

a hydrophobic paper-based strip housing element configured for placement of one or more testing strips;

one or more alignment markers positioned on the hydrophobic paper-based housing element configured to facilitate placement of the one or more testing strips;

a cover element arranged above the strip housing element and including a machine-readable test identifier on an upper surface; and

a removably attached filtering element configured to remove contaminates that can change a shade of the one or more testing strips and arranged on the hydrophobic paper-based strip housing element to reduce a distortion of an image of the one or more testing strips.

2. The testing strip device according to claim 1 , further comprising a color reference information area arranged on an upper surface of the cover element for result interpretation and digitalization by a digital Information Technology (IT) system, wherein:

the one or more testing strips received by the hydrophobic paper-based strip housing element display colorimetric results, and

at least one of the machine-readable test identifier or the color reference information identifies the test being performed.

3. The testing strip device according to claim 2 , wherein:

the one or more testing strips comprise a plurality of testing strips, and

the hydrophobic paper-based strip housing element is configured to secure the plurality of the testing strips for simultaneous immersion in a sample for multiplexed testing of the sample.

4. The testing strip device according to claim 3 , wherein at least some of the plurality of testing strips secured by the hydrophobic paper-based strip housing element are configured to perform different chemical testing of the sample, respectively.

5. The testing strip device according to claim 1 , wherein:

the hydrophobic paper-based strip housing element comprises a plurality of channels formed by the strip housing element and extends in a longitudinal direction, and

each respective channel of the plurality of channels has a length and a width configured to receive one testing strip of the one or more testing strips.

6. The testing strip device according to claim 1 , wherein:

the hydrophobic paper-based strip housing element comprises a plurality of grooves extending in a longitudinal direction, and

each respective groove of the plurality of grooves has a length and a width configured to receive one testing strip of the one or more testing strips.

7. The testing strip device according to claim 1 , wherein:

the removably attached filtering element is adhered to the upper surface of the cover element, and

the filtering element is configured to filter the sample.

8. The testing strip device according to claim 7 , wherein the removably attached filtering element is configured to filter samples comprising at least one of particulates of the liquid sample, soil, or wastewater.

9. The testing strip device according to claim 1 , wherein the removably attached filtering element comprises a peelable filtering element comprising a filtering paper portion and a carrier portion arranged along part of a periphery of the filtering paper portion.

10. The testing strip device according to claim 8 , wherein the carrier portion is configured to peelably remove the filtering element from the test device to enhance viewing of the testing strips to facilitate a result determination and a digitalization of the sample tested.

11. The testing strip device according to claim 1 , wherein the one or more testing strips received by the hydrophobic paper-based strip housing element display colorimetric results, and the testing strip device further comprises a timer element configured to indicate a predetermined time period at which a testing of the input sample is complete.

12. The testing strip device according to claim 11 , wherein the timer element comprises a paper-based hydrophilic timing channel formed by a hydrophobic material, wherein the timer element provides a colorimetric display when a predetermined period of testing time for a test being performed by one or more of the testing strips has elapsed from a contact of the sample with the timer element.

13. The testing strip device according to claim 12 , wherein the predetermined period of time at which the timer element visually indicates that a testing time has elapsed is configured based on one or more of the viscosity of the sample being tested, an impedance of the paper path, and the test performed by the testing strips.

14. The testing strip device according to claim 1 , wherein the cover element comprises a top cover having a transparent portion configured to view test results of the one or more testing strips and to facilitate an image capture or a visualization of the one or more testing strips for result interpretation and digitalization.

15. A method of manufacturing a multiplexed chemical testing strip device, comprising:

configuring a hydrophobic paper-based strip housing element configured to receive one or more testing strips for testing a sample;

providing the strip housing element with one or more alignment markers for arrangement of the one or more testing strips;

arranging a cover element above the strip housing element and including a machine-readable test identifier on an upper surface of the cover element; and

arranging a removably attached filtering element configured to remove contaminates that can change a shade of the one or more testing strips on the strip housing element to reduce a distortion of an image of the one or more testing strips.

16. The method according to claim 15 , further comprising providing a color reference information area on an upper surface of the cover element for result interpretation and digitalization by a digital Information Technology (IT) system, wherein at least one of the machine-readable test identifier or the color reference information, identifies the test being performed.

17. The method according to claim 16 , wherein the one or more testing strips comprise a plurality of colorimetric testing strips, and the method further comprises configuring the hydrophobic paper-based strip housing element to secure the colorimetric testing strips for simultaneous immersion in a sample for multiplex testing of the sample.

18. The method according to claim 16 , wherein the removably attached filtering element is configured for filtering a turbid sample by adhering the removably attached filtering element to the cover element along a periphery to be peelable from the multiplexed chemical testing strip device after performing a filtering operation of the turbid sample.

19. A multiplexed chemical testing strip device, comprising:

a hydrophobic paper-based strip housing element configured to receive a plurality of colorimetric testing strips;

one or more alignment markers arranged on the hydrophobic paper-based housing element for placement of the plurality of colorimetric testing strips;

a cover element arranged above the strip housing element and including a machine-readable test identifier comprising a Quick Response (QR) code, a barcode, or a Radio-Frequency Identification (RFID) on an upper surface;

a removably attached filtering element configured to remove contaminates that can change a shade of the one or more testing strips and arranged on the hydrophobic paper-based strip housing element to reduce a distortion of an image of the one or more testing strips; and

a color reference information area on an upper surface of the cover element configured to provide a result interpretation and a digitalization by a digital Information Technology (IT) system, wherein at least one of the machine-readable test identifier or the color reference information identifies the test being performed.
