Abstract: Systems and method are disclosed for measuring an analyte (e.g., glucose) in a fluid (e.g., blood) using a tunable source. The system can draw blood from a patient and deliver the blood to a sample cell. Some or a particular component of the fluid (e.g., plasma) may be positioned at a sample portion of the sample cell for measurement. The sample cell can include a cuvette with two window pieces defining a gap for fluid analysis. Wider gaps can facilitate measurement of larger biological fluid components, and laser optical sources can provide sufficient power to traverse larger gaps. Tunable sources can provide for measurement of a wider variety of components. Aspects of the system can be adjusted to accommodate measurement of multiple analytes with multiple wavelengths.

Abstract: Various embodiments disclosed herein relate to measuring multiple analytes in a medical system configured to draw in biological fluids. The system can include a fluid handling network configured to receive a fluid sample drawn from a patient and to deliver at least a portion of the fluid sample to an analyte measurement system. The measurement system can include a flow cell incorporated in line in a fluid system, shaped to allow a light source to directly abut the flow cell and cause radiation to pass through to a spectrometer on the other side.

Abstract: A selectively protected electrical system includes or operates with a power source, a load, a power driver circuit for controllably transferring power from the power source to the load, the power driver circuit being encapsulated in a potting material, and a controller for enabling and disabling the power driver circuit, the controller being un-encapsulated by the potting material. If a contaminant induced electrical fault occurs in the selectively protected electrical system, the electrical fault is more likely to occur in the un-encapsulated controller, such that the selectively protected electrical system is disabled. The contaminant is inhibited from contacting and inducing an electrical fault in the power driver circuit, thus providing for a controlled failure of the selectively protected electrical system.
