Abstract: An optical blood monitoring system for blocking unwanted light from reaching sensors in a sensor clip assembly fastened to a blood chamber connected in an extracorporeal blood treatment system. The blood chamber has an internal flow cavity for communicating the extracorporeal blood flow and viewing windows to enable the sensor clip assembly to illuminate the blood with light as the blood flows through the blood chamber in order to monitor characteristics of the blood. The sensor clip assembly includes opposing heads with LED emitters and photodetectors. In one embodiment, lenses in the heads are surrounded by shrouds extending from the lenses so that when the sensor clip assembly is fastened to the blood chamber the shrouds block unwanted light from reaching the photodetectors. Either alternatively or as a complement to the shrouds, the blood chamber includes an opaque portion or a portion colored to attenuate particular wavelengths of light to further enhance the overall ability of the blood chamber and sensor clip assembly to block unwanted light from reaching the photodetectors.

Abstract: A sensor mounting system having a suction cup array is disclosed. In one application, the system eases the initial positioning of the colorimeter on the screen to be measured, minimizes the force applied to the screen upon which it is mounted, and minimizes the distortion in the mounted area of the screen surface. In addition, the mounting system can be configured so that the distance from the colorimeter sensor to the screen will not significantly change over time. Such positional stability operates to improve SNR. The mounting system is further adapted for ease of removal from the screen upon which it is mounted. Applications not only include a mount for low to high accuracy colorimeters, but also for other measurement devices that can benefit from advantages of the present invention. Injection molding manufacturing techniques can be employed in fabrication of the system.

Abstract: The dispersion photometer described is designed particularly for the kinetic determination of total proteins and has a light source (20), an optical system, a removable optical cell (24) in the sample chamber, a stirrer, a photo-electric sensor (38) which receives light scattered forward at an angle, and an electronic processing and display unit (46) connected in series with the photo-electric sensor (38). All the elements located between the light source (20) and the optical cell (24), and between the optical cell (24) and the photo-electric sensor (38), have a coefficient of transmission or reflection in the visible region of the spectrum which is as high as possible, and do not reflect or absorb selectively.

Abstract: An injection system for use with a luminometer, comprises a carrier (15,16,32) movable between a liquid loading station and a liquid dispensing station and a dispenser assembly mounted on the carrier and including an injector needle (33) arranged, when at the liquid loading station, to pass through an aperture (39) in a part of the luminometer aligned with a test sample container (9) therein, the container being in a test chamber with which a photomultiplier device communicates. The system also includes a sealing arrangement (23,41,43,49) which prevents light from passing through the aperture in the luminometer, both when the needle extends through the aperture and when the needle has been withdrawn from the aperture.

Abstract: In this sample measuring device a lifting mechanism conveys a sample container from a rack to a sample measuring chamber. An inside light-shielding structure is extended over the upper surface of a base frame and the lower surface of a head, and surrounds a shaft. The inside light-shielding structure is configured from a first ring groove and a first ring protrusion. When the head is in a ground state, the upper surface of the base frame and the lower surface of the head are contacted by the action of a spring. At this time, the first ring groove and the first ring protrusion are integrated. An outside light-shielding structure is provided to the periphery of the inside light-shielding structure. A top plate contains a laminate structure which includes a lightshielding sheet and a lightreflecting plate.
