A point on just the center of two initial division points as the end points of the block is set as a sample point. A spline function through the three points in the appropriate block is obtained as a first approximate curve. Next, a distance l between the approximate curve and the outline at respective points in the block is calculated. A point on the outline with a maximum l is set as a new sample point, and a spline function through four points, i.e. this new point and the previous three points, is obtained as a new second approximate curve. Similarly, a distance l between the new approximate curve and the outline at respective points in the block is calculated. A point on the outline with a maximum l is set as a new sample point, and a spline function through five points, i.e. this new point and the previous four points, is obtained as a new approximate curve. The outline is approximated by obtaining approximate curves for all the blocks by the repeat of the above operation.

IPC: G01N33/49
Filed: 1991-07-19
Abstract: PURPOSE: To easily detect a viscosity change of liquid possessing an electrolyte solution characteristic by mainly providing an electrical insulating receptacle, a vibration field generating means, and a detecting means. CONSTITUTION: When blood is introduced, an electrolytic cell 1 starts to let electricity flow to a resistor 10, and at the same time, a vibration generating device 21 starts to move for causing blood congelation. Synchronously, voltage generation from terminals 5a, 6a in the electrolytic cell 1 is recorded with a time when the blood 7 is introduced, a circuit is closed, and initialization for the start of measurement is carried out. Until an artificially restricted voltage part takes an ordinary polarization curve again, a time actually handling blood congelation is recorded. An operator can directly read a congelation time from this record. The coagulation time can be measured by means of a signal processor provided with an electronic counting means. This method is superior to a conventional one as the measuring time has no dependency on the liquid volume.
