摘要： The invention relates generally to methods of monitoring and controlling the processing of blood and blood samples, particularly the separation of blood and blood samples into its components. In one aspect, the invention relates to optical methods, devices and device components for measuring two-dimensional distributions of transmitted light intensities, scattered light intensities or both from a separation chamber of a density centrifuge. In embodiment, two-dimensional distributions of transmitted light intensities, scattered light intensities or both measured by the methods of the present invention comprise images of a separation chamber or component thereof, such as an optical cell of a separation chamber. In another aspect, the present invention relates to multifunctional monitoring and control systems for blood processing, particularly blood processing via density centrifugation. Feedback control systems are provided wherein two-dimensional distributions of transmitted light intensities, scattered light intensities or both are measured, processed in real time and are used as the basis of output signals for controlling blood processing. In another aspect, optical cells and methods of using optical cells for monitoring and control blood processing are provided.

摘要： The invention relates to apparatus for controlling the processing of blood into blood components, particularly components for stroboscopic LED light sources for centrifuges. The stroboscopic apparatus comprises a first light source with reflective surfaces spaced around a central illumination axis, and light-emitting diodes spaced away from the axis radially outward from the reflective surfaces. An additional light source comprises a modified parabolic reflector surrounding a light emitting diode, the parabolic reflector having walls spaced outwardly from an axis of symmetry such that focal points fall radially outwardly from a center of the LED, forming a circular focal area. A controller that energizes the diodes for selected periods of time comprises a pair of switches connected in series, with an LED connected between the switches. One of the switches is connected to ground and is closed at the end of a period of illumination.
