Abstract
A multi-part system to collect and analyze constituents of body fluid. The use of a multilayered gel matrix to facilitate the collection of analytes fluid and a chemistry detection methodology incorporated into the matrix to aid in the visual or electronic determination of the analyte is described.
Claims15
An integrated system for biological fluid constituent analysis, comprising:
- collector means for non-invasively collecting a body fluid analyte from a patient and indicator means responsive to the body fluid analyte for indicating a condition of the body fluid analyte;
- ethyl ether to be brought in contact with the patient's skin for enhancing a diffusion rate thereof;
- and
- electronic interpretation means receiving said indicator means and electro-optically interpreting said indicator means with regard to the condition of the body fluid analyte.
A collection and indication apparatus for biological fluid constituent analysis, comprising:
- collector means for non-invasively collecting a body fluid analyte from a patient in the form of a multi-layer laminate including a chemical reactant layer, an activation gel layer disposed below said chemical reactant layer, and a collection gel layer disposed below said activation gel layer;
- ethyl ether to be brought in contact with the patient's skin for enhancing a diffusion rate thereof;
- and indicator means contiguous with said collector means and responsive to the body fluid analyte for indicating a condition of the body fluid analyte.
A collection and indication apparatus for biological fluid constituent analysis, comprising:
- collector means for non-invasively collecting a body fluid analyte from a patient in the form of a multi-layer laminate including a chemical reactant layer, an activation gel layer disposed below said chemical reactant layer, and a collection gel layer disposed below said activation gel layer;
- solvent material to be brought in contact with the patient's skin for enhancing a diffusion rate of the skin, said solvent material being selected from the group consisting of ethyl chloride, freon, DMSO, ether and silicone oil;
- and
- indicator means contiguous with said collector means and responsive to the body fluid analyte for indicating a condition of the body fluid analyte.
A collection and indication apparatus for biological fluid constituent analysis, comprising:
- collector means for non-invasively collecting a body fluid analyte from a patient in the form of a multi-layer laminate including a chemical reactant layer, an activation gel layer disposed below said chemical reactant layer, and a collection gel layer disposed below said activation gel layer;
- solvent material to be brought in contact with the patient's skin for enhancing a diffusion rate of the skin;
- and
- indicator means contiguous with said collector means and responsive to the body fluid analyte for indicating a condition of the body fluid analyte wherein said solvent material is microencapsulated material disposed in said gel layer.
