Abstract: A prismatic reflector is provided for incorporation into a centrifugal separation chamber. The prismatic reflector is formed of a light-transmissive material and includes inner and outer walls and first and second end walls. The inner wall is configured to receive light traveling along an initial path and transmit the light to the first end wall, with the first end wall receiving the light transmitted through the inner wall and directing the light toward the second end wall in a direction that is angled with respect to the initial path. The second end wall receives the light from the first end wall and transmits the light out of the prismatic reflector. The initial path of the light may be in a direction toward a rotational axis of the centrifugal separation chamber, with the prismatic reflector redirecting the light into a direction substantially parallel to the rotational axis.

Abstract: A collapsible splint includes an expandable frame within a flexible generally rectangular sleeve. The expandable frame includes a number of members that are extendable rods or tubes. The members are oriented longitudinally within the sleeve and arranged transversely across the sleeve and adjacent to one another. The rods are secured at one end of the sleeve and are connected to one another by transverse links to form the frame. The sleeve includes an opening through which the frame can be accessed and extended to a desired length. The sleeve also includes straps on its rear side suitable for binding the collapsible splint around a fractured limb.
