    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.

    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. A digital control circuit controls a high amperage linear voltage regulator. The voltage regulator charges a capacitor bank, which in turn powers LED light sources. The digital control circuit comprises an N-channel switched mode FET. The switched mode FET receives a pulsed digital signal from the microprocessor controlling the blood processing apparatus. A by-pass resistor in parallel with the FET allows most of the current to flow past the FET, thus minimizes heating of the FET. The performance of the FET, therefore, remains stable despite extended use of the apparatus.

    摘要: A centrifugal blood separation apparatus having an optical camera control system with a focused, stationary light source. A diffusion plate mounted on a rotor, rather than on or near the light source, allows an intense light beam to be transmitted from the light source to the rotor and then diffused at the rotor across an observation region. Different characteristics of a diffusion surface allow different lighting regions within the observation region. The diffusion plate has upper and lower plates with a diffusion surface sealed between the plates. This prevents degradation or contamination of the diffusion surface by abrasion, dirt, blood components or other materials that might incidentally contact the diffusion surface.
