A ten-channel coagulometer has been designed. Its operation principle is based on the clotting method using a monitoring ball and magnetic transducers. The coagulometer consists of a recording unit and a unit of a thermostatic switch and a ball dosing apparatus. The device may operate off-line or may be connected to a personal computer. It has a specialized software and a medical manual. The analyzer may be used in clinical diagnosis laboratories for coagulation tests.

[A flow laser analyzer of erythrocyte deformability].

The analyser of erythrocyte deformation has been worked out, it allows one to obtain the distribution of the cells according to the deformation degree. The analyser consists of optic electronic block, sample insert unit, signal transformation unit and the information processing unit. The analyser is based on the principle of the small angle light dispersion of laser radiation registration made on each erythrocyte of the population, which was extended due to the influence of the shift efforts when the cell is passing through the narrow measuring capillary. The analyser was tested with the suspension model, normal and pathological blood samples. The analyser can be used for diagnosis and treatment of diseases related to the rheological blood properties.

[Laser flow-type counter-analyzer for microparticles].

A flow-type instrument for studying microparticles distributed in liquid suspensions is presented. With the instrument, one can determine concentrations of microparticles, their size distribution, perform computer-based data analysis. Considerations are also given to the main units of the instrument, their characteristics, and data acquisition and processing.

[Blood viscosity analyzer].

An analyzer that determines blood viscosity at different shift speed has been designed. Its operation principle is based on the use of rotation viscosity measurement using a rotor freely floating in the sample. A blood sample is placed between the stationary thermostabilized measuring cylinder and a free floating rotor. The system creates a rotating magnetic field which makes the rotor rotate with a preset speed, determines shift stress, calculates the magnitude of viscosity and indicates it on the display. The magnitude of viscosity is proportional to the square of the current drawn in the windings of a stator, which divided by the rotational speed of a rotor. The analyzer provides viscosity measurements in the range of 0.7-14 mPa.sec at shift rate of 20-200 sec-1, the sample volume is less than 1 cm3. The device can be used for the diagnosis of the diseases whose pathogenesis microcirculatory and coagulative disorders play an important role in.
