Abstract

A system is provided for detecting a presence or amount of an analyte in a sample. The system may include a detection device detecting a characteristic of a fluid in communication with the sample to generate an electrical signal corresponding to the characteristic of the fluid and a processor coupled to the detection device and determining at least one property relating to the analyte, based on the electrical signal. The system may also include a telephone interface device. The telephone interface device may be coupled to the processor and responsive to the processor to transmit an alarm message indicating the property of the analyte to at least one telephone communication device.

Claims

1. A system for detecting a presence or amount of an analyte in a sample, comprising:

a detection device detecting a characteristic of a fluid in communication with the sample to generate an electrical signal corresponding to the characteristic of the fluid;

a processor coupled to the detection device and determining at least one property relating to the analyte, based on the electrical signal; and

a telephone interface device, coupled to the processor and responsive to the processor to transmit an alarm message indicating the property of the analyte to at least one telephone communication device.

2. The system of claim 1, wherein the characteristic comprises a light level.

3. The system of claim 1, wherein the property of the analyte comprises a concentration level of the analyte.

4. The system of claim 1, wherein the telephone interface device transmits the alarm message to a land-line telephone.

5. The system of claim 1, wherein the telephone interface device transmits the alarm message to a cellular telephone.

6. The system of claim 1, wherein the telephone interface device transmits the alarm message to a facsimile device.

7. A microbiological alert system for detecting contamination in a sample, comprising:

a detection device detecting a light from a fluid in communication with the sample to generate an electrical signal corresponding to the light from the fluid;

a processor coupled to the detection device and determining a presence of microorganisms in the test sample based on the electrical signal; and

a telephone interface device, coupled to the processor, and responsive to the processor to transmit an alarm message indicating the presence of microorganisms,

wherein the presence of microorganisms is determined by the processor based upon the at least one parameter and a predetermined alarm criterion.

8. The system of claim 7, wherein the telephone interface device comprises a telephone modem for transmitting the alarm message to one or more telephone devices.

9. The system of claim 7, further comprising:

a light source transmitting light to the fluid.

10. The system of claim 7, further comprising:

a liquid media containing the test sample, the liquid media facilitating growth of microorganisms and altering the value of at least one characteristic in response to metabolic byproducts of microorganisms.

11. The system of claim 10, wherein the processor comprises a processor analyzing the value of the at least one characteristic over time.

12. The system of claim 11, wherein the processor analyzes the value of the at least one characteristic in predetermined time intervals.

13. The system of claim 10, wherein the processor comprises a processor analyzing the value of the at least one characteristic over time, thereby determining at least one of the presence of or the level of microorganisms in the liquid media.

14. The system of claim 13, wherein the processor analyzes the value of the at least one characteristic in predetermined time intervals.

15. The system of claim 10, further comprising:

a barrier region in communication with the liquid media.

16. The system of claim 15, wherein the barrier region comprises a fluid portion and a non-fluid portion, the fluid portion being in equilibrium with the liquid media.

17. A microbiological alert system, comprising:

detection means for generating data corresponding to at least one parameter relating to a property of an analyte in a test sample;

processor means for receiving the data from the detection means;

means for storing processor instructions to be executed to determine an alarm state based upon at least the parameter and a specified alarm criterion; and

telephone interface means, controlled by the processor means, for transmitting an alarm message indicating the alarm state to an external telephone device.

18. The system of claim 17, wherein the property of the analyte includes a concentration level of a microorganism.

19. The system of claim 17, further comprising:

a liquid nutrient media facilitating growth of microorganisms and affecting the value of the parameter by detection of metabolic byproducts of the microorganism.

20. The system of claim 19, wherein the value of the parameter is analyzed over time to determine whether the metabolic byproducts are being generated.

21. The system of claim 17, wherein the telephone interface means comprises means for transmitting the alarm message to a land-line telephone.

22. The system of claim 17, wherein the telephone interface means comprises a telephone modem capable of dialing predetermined telephone numbers.

27. The system of claim 17, wherein the telephone interface means comprises means for transmitting the alarm message to a facsimile device.

28. A method for detecting and alerting a presence or amount of an analyte in a test sample, comprising:

generating an electrical signal corresponding to a characteristic related to the analyte in the test sample;

determining at least one parameter relating to the characteristic based on the electrical signal;

determining an alert condition indicating the presence of the analyte based upon the at least one parameter and a predetermined alarm criterion; and

communicating the alert condition to an external telephone device via a telephone communication channel.

29. The method of claim 28, wherein the characteristic is light transmissibility, the method further comprising:

transmitting light to the test sample.

30. The method of claim 28, wherein the alert condition indicates level of microorganisms.

31. The method of claim 28, wherein communicating further comprises:

dialing a predetermined telephone number to connect to the external telephone device; and

sending an audible alarm message regarding the alarm state to the external telephone device.

32. The method of claim 31, further comprising:

sending a text alarm message to the external telephone device using short message service (SMS).
