AI Technical Summary

Benefits of technology

The device provides high-resolution, immediate, and accurate measurements of substance concentrations, reducing pain and inconvenience for users, as it is easy to operate and transport, and does not require blood processing or collection.

Problems solved by technology

Monitoring or detecting a concentration of a substance typically requires a set up of relatively complex, sensitive, and expensive equipment or instrumentation.
Additionally, such complex equipment may not provide results which are of a high resolution.
Since finger pricking or lancing is required for self monitoring levels of glucose in a patient, many patients avoid this because it is painful and inconvenient.
Although these devices use noninvasive methods, in that no blood is collected, none of these devices have been commercially accepted or viable.

Embodiment Construction

[0023] Referring now to the drawings, wherein like numbers refer to like items, number 10 identifies a preferred embodiment of a micro optical sensor device constructed according to the present invention. As illustrated in FIG. 1, the device 10 comprises a pencil or pen shaped body 12 which includes a tip portion 14, a central body portion 16, and an end cap 18. The central body portion 16 further includes a display device 20, such as an LED (light emitting diode) type display or an LCD type display, for displaying information. The end cap 18, which may be removable from the central body portion 16, is used to allow access into the interior of the central body portion 16. Batteries (not shown) can be inserted into the central body portion 16 to supply power to the device 10, as will be explained. The central body portion 16 may also include an ON / OFF switch 22 which may be used to operate the device 10. Other switches (not shown) may be incorporated into the central body portion 16 ...

Abstract

A method of using a sensor device for measuring a concentration of a substance within a sample includes inserting a tip portion of a sensor into a sample. The sensor has an optical transmission member having a first end and a second end. The second end has the tip portion attached thereto and an active material incorporated within the tip portion. The active material is capable of interacting with a substance within the sample. The method includes producing a reflected beam of light from the interaction of the active material with the substance within the sample, the reflective beam of light having a second wavelength different from the first wavelength. The method includes determining the concentration of the substance based on the reflected beam of light.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation-in-part of U.S. patent application Ser. No. 09 / 729,611, filed on Dec. 4, 2000 which is a continuation of U.S. patent application Ser. No. 09 / 100,295 filed Jun. 19, 1998, now U.S. Pat. No. 6,157,442.BACKGROUND OF THE INVENTION [0002] This invention relates generally to a sensor device and more particularly to a micro optical sensor device which may be employed in a variety of sensor applications to monitor, sense, or measure a concentration of a material within a sample. [0003] There are numerous applications in which a device is used to monitor or detect a concentration of material within a substance. For example, it may be required to know the concentration of a chemical in a sample of material such as knowing the concentration of sodium, calcium, or some other chemical composition in a sample. Monitoring or detecting a concentration of a substance typically requires a set up of relatively complex, sensitive, and...
