    Abstract: The spectrophotometer comprises a light source (13), a first diffusing element (17), a second diffusing element (24), a test cuvette filled with the fluid to be investigated arranged between the first (17) and second light diffusing element (24) and a photodetector (26) adjacent to the second light diffusing element (24). Light coming from the source (13), is randomly scattered within the first light diffusing element (17) transmitted through the test fluid (21) in the cuvette (20) gathered by the second light diffusing element (24) and converted into an electric signal by photodetector (26). The electric signal is then further processed and monitored by an appropriate electronic circuitry (30, 32, 35). The light diffusing elements (17) and (24) are preferably integrating spheres.

    Abstract: A method and apparatus for sensing the presence of bubbles in a liquid wherein radiation is directed through said liquid toward a radiation responsive sensor and the differential between the response of the sensor when a bubble is not present in the radiation path and the response thereof when a bubble is present in the radiation path is markedly increased by limitation of the radiation which can reach said sensor to wavelengths strongly absorbed by said liquid.

    Abstract: The invention relates to a method of detecting the presence of a gas or a liquid in a conduit by sensing the reflective properties of a flat surface which is being obliquely illuminated by semi-monochromatic light on the said surface which is an inner wall of the conduit, said surface being optically reflective when a gas is present in the conduit, and transmissive when a liquid which has an index of refraction significantly higher than that of the gas is present in the conduit as well as to an apparatus therefor.

    Abstract: Bubble detecting infusion apparatus for infusing a liquid from a source into a patient through the lumen of a light transmissive conduit member, which lumen has a flat wall surface portion contacted by the liquid in the lumen, the conduit member having an operative position within a yoke in which it is removable disposed, the yoke having a light source for directing a light beam through the conduit member wall toward the flat lumen wall surface portion thereof and having a light sensor positioned to receive light from the source reflected through the conduit member wall by the flat lumen wall surface portion, the angularity between the incident light beam and the normal to the flat lumen wall surface portion being such that when a gas bubble is in contact with the lumen flat wall surface portion, substantially all light from the source incident thereon is reflected by said surface portion toward the light sensor, and when a bubble-free liquid is in contact with the lumen flat wall surface portion, said surface portion is not substantially reflective. Shoulder means on the yoke and conduit member cooperate, when the conduit member is in operative position, to prevent rotation of the conduit member and thereby to maintain the desired angularity of the flat lumen wall surface portion with respect to the light source and the light sensor.
