Abstract

The invention provides for a urinary monitoring device to monitor for the presence or absence of markers indicative of a urinary tract infection (UTI). The invention also provides for methods of using such a device.

Claims

1. A urinary tract infection (UTI)-monitoring urinary catheter system for monitoring the presence or absence of one or more markers in urine that are indicative of a urinary tract infection (UTI) comprising a catheter portion, a collection tubing portion, and a collection bag portion, wherein said collection tubing portion or said collection bag portion further comprises multiple UTI indicator substrates, wherein said multiple UTI indicator substrates are configured to be serially exposed to multiple freshly voided urine specimens, wherein said multiple UTI indicator substrates are sequestered from the urine but, when exposed to a freshly voided urine specimen, are capable of detecting and signaling the presence or absence of one or more markers in said freshly voided urine specimen that are indicative of a UTI.

2. The UTI-monitoring urinary catheter system of claim 1, wherein said UTI indicator substrate is separately and sequentially exposed to urine inside of said collection tubing portion or said collection bag portion.

3. The UTI-monitoring urinary catheter system of claim 1, wherein said multiple UTI indicator substrates are releasably attached to an inside surface of said collection tubing portion or said collection bag portion.

4. The UTI-monitoring urinary catheter system of claim 1, wherein each of said multiple UTI indicator substrates detects leukocyte esterase.

5. The UTI-monitoring urinary catheter system of claim 1, wherein at least one of said multiple UTI indicator substrates detects nitrites.

6. The UTI-monitoring urinary catheter system of claim 4, wherein each of said multiple UTI indicator substrates further detects nitrites.

7. The UTI-monitoring urinary catheter system of claim 1, wherein the UTI indicator substrate comprises an antibody that has a specific binding affinity for said one or more markers in urine that are indicative of a UTI.

8. The UTI-monitoring urinary catheter system of claim 1, wherein the presence of one or more markers in said freshly voided urine is indicated by a word, symbol, or colorimetric change.

9. The UTI-monitoring urinary catheter system of claim 1, wherein the signaling the presence or absence of one or more markers in said freshly voided urine specimen that are indicative of a UTI is a word, symbol, or colorimetric change.

10. The UTI-monitoring urinary catheter system of claim 1, wherein the signaling the presence or absence of one or more markers in said freshly voided urine specimen that are indicative of a UTI comprises an electronic signal.

11. The UTI-monitoring urinary catheter system of claim 10, wherein the electronic signal is a digital read out or a light.

12. The UTI-monitoring urinary catheter system of claim 10, wherein the electronic signal is at a location that is remote from said UTI-monitoring urinary catheter system.

13. An UTI monitoring device for monitoring the presence or absence of one or more markers in urine that are indicative of a urinary tract infection comprising

a first port on one end and a second port on the other end, wherein said first and second ports are configured for in-line placement within a urinary catheter system, wherein, located between said first and second ports are multiple UTI indicator substrates, wherein said multiple UTI indicator substrates are configured to be serially exposed to multiple freshly voided urine specimens, wherein said multiple UTI indicator substrates are sequestered from the urine but, when exposed to a freshly voided urine specimen, can detect and signal the presence or absence of said one or more markers in said freshly voided urine specimen that are indicative of a UTI.

14. A urinary tract infection (UTI)-monitoring urinary catheter system for monitoring the presence or absence of one or more markers in urine that are indicative of a urinary tract infection (UTI) comprising a catheter portion, a collection tubing portion, and a collection bag portion, wherein said collection tubing portion or said collection bag portion further comprises multiple UTI indicator substrates, wherein said multiple UTI indicator substrates are configured to be serially exposed to multiple freshly voided urine specimens, wherein said multiple UTI indicator substrates are sequestered from the urine but, when exposed to a freshly voided urine specimen, are capable of detecting and signaling the presence or absence of one or more markers in said freshly voided urine specimen that are indicative of a UTI, wherein said signaling comprises a visible signal.

15. The UTI-monitoring urinary catheter system of claim 14, wherein said visible signal is a word, symbol, or colorimetric change.

16. The UTI-monitoring urinary catheter system of claim 14, wherein the visible signal is an electronic signal.

17. The UTI-monitoring urinary catheter system of claim 16, wherein the electronic signal is a digital read out or a light.

18. The UTI-monitoring urinary catheter system of claim 16, wherein the electronic signal is at or near a patient using the UTI-monitoring urinary catheter system.

19. The UTI-monitoring urinary catheter system of claim 16, wherein the electronic signal is at a location remote from a patient using the UTI-monitoring urinary catheter system.
