BLOOD HAEMATOCRIT MEASUREMENT

摘要

Disclosed is a process and apparatus for the determination of parameters of particles suspended in a liquid, particularly for the parameters of shaped blood particles. As the suspension is caused to flow through a capillary there is generated a signal that is characteristic of the number and size of the particles and the information concerning the number of particles passing through it is stored digitally. The pulses of the signal characterizing the number and size of the particles are selected according to amplitude and time duration. The amplitude value of the pulses corresponding to the selection conditions are digitally determined and summed, and further a storage area is designated with a digital value of the amplitude for the reception of data concerning the volume distribution of the particles and thus the value of the mean cell volume and the distribution curve of the cell volume are determined simultaneously.
