Latest Patents
One of John K Lazier's latest patents is a medical-analytical gas detector designed for transcutaneous measurement of CO.sub.2 concentration in the blood. This innovative gas analyzer circulates sample gases from the body within a cavity of the device. A rotating wheel inside the cavity features two reference cells and a sample cell, which are sequentially rotated into the optical path between a source and a detector. This mechanism generates three signals that can be combined to provide an output indication of the CO.sub.2 concentration in body fluids. In a preferred embodiment, the sample cell is an 'inverted cell' that remains in open communication with the circulating sample gas, ensuring that the gas in the sample cell is a portion of the circulating gas surrounding the reference cells. This design allows for an output indication that is insensitive to contaminants in the sample. Another embodiment isolates the sample cell from the surrounding region, positioning it in series with the reference cells in the optical detection path. The rotating wheel is equipped with permanent magnets that interact with electromagnets, enabling its rotation.
