Abstract
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.
