    摘要： A blood parameter measurement device especially useful for surgical procedures includes a compact housing with a light source, light detector and signal converter contained within the housing. In use, the device is releasably coupled to a cassette that can be either used as an in-line cell in series with a cardiopulmonary by-pass circuit, or in another passageway that shunts the cardiopulmonary by-pass circuit. Preferably, the housing of the device has a longitudinal axis that extends in a direction generally parallel to the direction of blood flowing through the cassette.

    摘要： A parameter of blood is sensed with a system which includes a catheter and a sensor and a volume oscillator element. The catheter has a lumen extending therethrough, a proximal end, a distal end and an opening, adapted to be placed in the blood vessel of a patient. The sensor senses a blood parameter and is adapted to be located outside the patient's body in fluid communication with the lumen. The volume oscillator element is in fluid communication with the lumen and is capable of acting to periodically cause blood to enter and exit the lumen. The system is structured so that a flush or anti-clotting solution flows into the patient when the volume oscillator element is inactive. With the volume oscillator activated, blood is moved back and forth in the lumen to expose the sensors to blood so that the blood parameter of interest can be sensed.

    摘要： A sensor probe for in-situ measurement of pH in a human tissue (e.g., cardiovascular) environment comprises a hollow needle having a tip and a back end. The tip is insertable through tissue into the tissue environment. An optic cable comprises a light conduit surrounded by a cladding. A first end of the light conduit not covered by the cladding is inserted from the back end of the needle and extends to within a predetermined distance of the tip to define a cavity within the tip. A porous dye layer is contained within the cavity adjacent to the first end of the light conduit, wherein the dye layer has a response to excitation light delivered through the light conduit that varies according to the pH of the tissue environment. An overcoat layer is deposited on the dye layer, wherein the overcoat layer is ionically permeable and substantially opaque at a light wavelength corresponding to the variable response of the dye layer.
