Abstract

An adhesive fluorescence measurement patch for use with a fluorescent light-emitting bead implanted within a user'"'"'s body includes an adhesive sheet configured for removable adhesion to the user'"'"'s body, a light emitter attached to the adhesive sheet, and a light detector attached to the adhesive sheet. The light emitter is configured for emitting light that is absorbed by the fluorescent light-emitting bead while the light detector is configured for detecting fluorescent light emitted by the fluorescent light-emitting bead.

Claims

1. An adhesive fluorescence measurement patch for use with a fluorescent light-emitting bead implanted within a user'"'"'s body, the adhesive fluorescence measurement patch comprising:

at least one adhesive sheet configured for removable adhesion to the user'"'"'s body;

a light emitter attached to the at least one adhesive sheet, the light emitter configured for emitting light that is absorbed by the fluorescent light-emitting bead; and

a light detector attached to the at least one adhesive layer, the light detector configured for detecting fluorescent light emitted by the fluorescent light-emitting bead.

2. The adhesive fluorescence measurement patch of claim 1, wherein the light emitter and light detector are attached to the at least one adhesive sheet in predetermined relationship relative to an imaginary optical axis of the adhesive fluorescence measurement patch, the imaginary optical axis being positioned in a predetermined juxtaposition to the fluorescent light-emitting bead when the adhesive fluorescence measurement patch is removably adhered to a user'"'"'s body.

3. The adhesive fluorescence measurement patch of claim 1, wherein the at least one adhesive sheet includes a top layer and at least one adhesive lower layer disposed on at least a portion of the top layer, with the adhesive lower layer configured for removably adhering the adhesive fluorescence measurement patch to the user'"'"'s body.

4. The adhesive fluorescence measurement patch of claim 3, wherein the adhesive lower layer is a segmented adhesive lower layer.

5. The adhesive fluorescence measurement patch of claim 3, wherein the adhesive measurement patch is symmetrically shaped in one dimension about an imaginary optical axis of the adhesive fluorescence measurement patch.

6. The adhesive fluorescence measurement patch of claim 5, wherein the adhesive measurement patch is circular.

7. The adhesive fluorescence measurement patch of claim 4, wherein adhesive contact locations between the segmented adhesive lower layer and the user'"'"'s body when the fluorescence measurement patch is in a first position are noncoincidental with adhesive contact locations between the segmented adhesive lower layer and the user'"'"'s body when the adhesive fluorescence measurement patch is in a second position.

8. The adhesive fluorescent measurement patch of claim 4, wherein the segmented adhesive lower layer includes a plurality of concentric circular segments.

9. The adhesive fluorescent measurement patch of claim 1 further including a power module, a micro-processor module, a driver/amplifier module and a transceiver module.

10. The adhesive fluorescent measurement patch of claim 1 further including at least one release liner.
