Description

transporting these probes through the ambient air, and then the operation of immersing the probes in the receiver 33 for washing liquid for a specified period of time. In the process of transporting probes through an air environment, a certain amount of air is sucked, and when immersed in the receiver, a certain amount of washing liquid is sucked. Then the probes are again transported through the surrounding medium and immersed in the next test tube installed by this time in the receiver for a specified period of time for suction of a new portion of air and subsequent suction of the measured volumes of plasma and blood cells.

When the probes are immersed in a test tube that controls the operation of three-way valves 34 and 35, the solenoid 36, which is under the control of the software device 21, sets the valve 34 to the closed position, and the valve 35 to the open position. As a result, a stream of washing liquid supplied by pipelines 37 and 38, separated by air gaps, will circulate through the office and pipelines 39, 40 and 41 and return to tank 42. When the probes are in intensive or gradual compression or squeezing the pipeline (not shown) of the pump through the inlet 29 of the probe 31 ensures the suction of a portion of blood plasma, which then through the outlet 43 of the probe and further along the pipeline 1 for blood enters the indicated a new compressible pump tube for further passage through it. Similarly, compression or squeezing of another pipeline will cause suction through the inlet 30 of the probe 32 portions of blood cells, which then through the outlet 44 and pipe 2 into the specified pump tube for further passage through it.

While the probes are in the receiver for the washing liquid, the solenoid 45 controlled by the software device sets the three-way valve 34 to the "open" position and the three-way valve 35 to the "closed" position. As a result, a gap of flushing fluid separated by air, fed to a three-way valve 34 through line 37, will be directed by a valve to the inlet 46 in the probe 32 for thoroughly flushing the probe cavity with subsequent passage through the external gyne tube 47, hole 48, inner hypotube 49 and outlet 44 probes, thereby ensuring the removal of residues of blood cells there.

Similarly, setting the three-way valve 35 to the closed position during immersion of the probe into the receiver for flushing liquid ensures flushing of air separated by air 38 through the pipeline 38, the three-way valve and to the plasma probe 31 inlet 50 to thoroughly flush the probe with subsequent exit

This jet through pipe 1 and a compressible pasosnuyu tube to remove the remainder of the plasma located here. At the time the probes are transported from the tube to the receiver, a solenoid,

working from a software device, will keep the three-way valves, respectively, in the position “closed and“ open, so the surrounding air gets through the corresponding inlet holes 29 and 30

to the corresponding pipelines 1 and 51, forming air gaps, which contributes to the flushing of the probe, the pipeline and the pumping pipeline, and makes it possible to clearly distinguish the plasma and cell parts of this

portions of blood.

Consequently, during operation of the device, a jet is formed consisting of individual portions or plasma doses taken from successive tubes 26, which are separated from one another sequentially: a void gap, a section of washing liquid, and again an air gap. The jet is supplied by a compressible pump line to the plasma line 51. Similarly, in

During the operation of the device, a jet is formed in phase, consisting of individual portions or doses of blood cells taken from test tubes, which are separated from one another sequentially: an air gap, a section of washing liquid and again an air gap. The jet is fed to the blood cell line 52.

The device provides a constant circulation of the washing liquid supplied by the pump tube through the receiver 33 for the washing liquid.
