Abstract

The invention refers to medical and laboratory technique and is destined for automatical preparation of solutions, liquid pharmaceutical means and especially for preparation of dialisys solution for the apparatus of peritoneal dialisys.The pwipose of invention is the dosage apparatus, consisting of a flexible tank 6 with pipeline for dosage liquid supply 8 and pipeline for of measured dose discharge 9 an electromagnetic valve 3 placed on the pipelines with the possibility by turns lap and a regulation block 22 let joined by its outlet with the electrical inlet of the valve 3, supplimentary introduced means for detection of the rear level of the measured liquid 21, the outlet of which is joined with the input of the regulation block 22, as well as rigid dosage vessel 5 with an elastic tank 6 inside it. The rigid dosage vessel 5 is filled with dosage liquid 19 to the point of initial count level 18. In the variant of a dosage apparatus the dosage liquid 19 is electroconductive, the means of detecting of the given level of the dosage liquid 21 is made in the form of several dosing electodes 11 placed on the same height as the vessel 10 in order to assure contact with the electroconductive liquid 19 and a common electrode 17, placed under the above mentioned point 18. The regulation block 22 contains an RS-trigger 2, the source of voltage drop 15 of the RS trigger and an electronic commutator is having informational 12 and address 16 input and output 14. The output of the voltage source drop 15 of the RStrigger is connected with the output 14 of the electronic commutator 13 with the informational inputs 12 connected with the corresponding dosage electrodes 11, and the electrode 17 is connected with the R-input of the RS-trigger, and the RSştrigger - with the electrical input of the electromagnetical valve 3.The dosage apparatus ensures dosage with high precizion of small amounts, weight and electroconsumption.
