Abstract: A control method of a shape measuring apparatus divides a curve indicating a movement path of a probe into a plurality of sections. A measurement target section is selected from the plurality of sections sequentially from a starting point side of the curve indicating the movement path of the probe. A first curvature radius is calculated from a curvature of the measurement target section. A second curvature radius is calculated according to an angle between a first straight line connecting a starting point to an ending point of the measurement target section and a second straight line connecting a starting point to an ending point of a section next to the measurement target section. A smaller value from among the first curvature radius and the second curvature radius is set as an effective radius. A maximum speed of probe movement increasing according to an increase in the effective radius is calculated for the measurement target section.

Abstract: A hollow filament type blood processing apparatus, typically dialyzer includes a bundle of multiple hollow filaments (3) for processing blood inserted in a housing (2). Inlet and outlet ports (12, 11) are disposed in the housing near its opposite ends for passing a dialysis fluid through the housing. The filament bundle is fixedly secured to the housing at its opposite ends by partitions (5, 6). Caps (9, 10) are fixedly attached to the opposite ends of the housing and each have a port for passing blood from one port (8) to the other port (7) through the hollow filaments. Each cap has received therein inside and outside elastomeric rings (17a, 17b). The inside elastomeric ring (17a) is interposed under pressure between the cap (9) and the partition (5). The outside elastomeric ring (17b) is interposed under pressure between the cap (9) and the housing (2). No blood leakage occurs between the caps and the housing.
