ABSTRACT:
An integral interstitial fluid sensor for application to the skin of a person or an animal for the detection of chemical components of tissue fluid is disclosed. The fluid sensor comprises a substrate of a porous material for the passage of the interstitial fluid therethrough. At least two electrodes are provided. One of the electrodes has two sides, with one side mounted on the substrate. The electrode is also of a porous material and permits the passage of the interstitial fluid from one side through to the second side which is generally opposite the one side. A layer of chemical is on the second side. The layer of chemical comprises a chemical for reaction with one component of the fluid, mixed in a mediating agent. The electrodes generate an electrical signal upon the detection of the reaction of the one component of the fluid with the chemical. The electrical signal is received by a detector and a display is generated, indicating the amount of the one component detected. Finally, a pump for sucking the fluid from the skin into the sensor is disclosed.
