A dividable short catheter tube made of a modifying polymer intermixed with, or inserted into, a base polymer. The modifying polymer is usually one which is incompatible with the base polymer. The dividable short catheter tube is readily tearable longitudinally so that it can be removed from around a flexible catheter after the flexible catheter has been guided into a patient by means of the short catheter previously positioned in a body puncture. The tube can be extruded from a mixture of the two polymers or it can be extruded with modifying polymer longitudinal strips in walls of the base polymer.

Dividable catheter

A device for facilitating rapid and accurate determination or measurement of sedimentation rates of fluid suspensions, e.g. erythrocytes in blood plasma, includes a sedimentation tube having open upper and lower ends, a scale with a zero point adjacent the upper end of the tube, and means for selectively opening and closing the tube adjacent said upper end, said means having a surface portion extending across the tube when the tube is closed, which surface portion is located precisely at the zero point in the scale.
