Abstract

A method for monitoring an implanted fluorescent light-emitting bead includes adhering and adhesive fluorescence measurement patch to a user'"'"'s body. The method also includes monitoring the implanted fluorescent light-emitting bead implanted in the user'"'"'s by emitting light from a light emitter included in the adhesive fluorescence measurement patch and detecting fluorescent light emitted from the fluorescent light-emitting bead with a light detector included in the adhesive fluorescence measurement patch.

Claims

1. A method for monitoring a fluorescent light-emitting bead implanted in a user'"'"'s body, the method comprising:

removably adhering a adhesive fluorescence measurement patch to the user'"'"'s body in a first position that is in operative alignment with the fluorescent light-emitting bead, wherein the adhesive fluorescence measurement patch includes

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; and

monitoring the fluorescent light-emitting bead implanted in the user'"'"'s body by emitting light from the light emitter and detecting fluorescent light emitted from the fluorescent light-emitting bead with the light detector.

2. The method of claim 1 further comprising the steps of:

removing the adhesive fluorescence measurement patch from the first position and readhering an adhesive fluorescence measurement patch in a second position.

3. The method of claim 2, wherein the removing step includes readhering an unused adhesive fluorescence measurement patch in the second position.

4. The method of claim 2, wherein the removing step includes readhering, in the second position, the adhesive fluorescence measurement patch that had been removed from the first position.

5. The method of claim 2, wherein adhesive contact locations of the first position are noncoincidental with adhesive contact positions of the second position.

6. The method 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.

7. The method of claim 1, wherein the monitoring step includes employing a remote module to control the light emitter and the light detector.

8. The method of claim 1, wherein the monitoring step includes employing a remote module to process communications from the adhesive fluorescence measurement patch.

9. The method of claim 1, wherein the at least one adhesive sheet includes a top layer and at least one segmented 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.
