The first Russian manufacturer of laboratory reagents has been deployed in the Dubna since 2013 and since then produces several laboratory reagents, including patented protein determinants. It is also planned to launch in the Dubna seven automated blood collection production lines, production of microtubes for capillary blood and vacuum tubes for venous blood. Such tubes, in addition to stationary use, are included in the first aid kits.
The production of vacuum tubes can be compared by its importance with the production of disposable syringes. It is strategically important to have a developed domestic medical industry that provides the basic needs of medical institutions. The analysis shows that the prices for medical products of domestic production, although growing due to inflation and an increase in the cost of imported components and raw materials, are several times less than the increase of prices for imported products.
The volume of production of test tubes consist of 41 million products in 2016. By the end of 2017, Dubna will provide the 40% of vacuum test tubes on domestic market of first aid kits. In addition to the routine research of biochemistry and general blood analysis, the laying of first aid kits of pro-epidemic services includes test tubes for gas analysis and BAC tests.
The polyethylene terephthalate tubes are distinguished by their strength, transparency and gas exchange. PET tubes do not break when carried in first aid kits and centrifugation packages and do not open spontaneously.
The blood taken to produce a serum or plasma is immediately centrifuged in such a test tube. Tubes with a hemorhepherent gel are also centrifuged, which irretrievably separates the serum from the cell part. Innovation of the process consists of the finely dispersed spraying of anticoagulant on the bottom of the test tube.
The troubles occur when standard glass tubes are delivered to the laboratory: test tubes can be beaten, blood can be poured or some of it can be absorbed into a cotton swab, and even can be dropped on the personnel skin. These problems are solved with the use of vacuum systems for blood taking.
Systems with negative pressure consist of a needle, an adapter between needle nd a test tube, and a test tube filled with a preservative.
The vacuum system is similar to a common syringe, but a differential pressure is used instead of a piston. The system is the most convenient to handle and, thanks to its compact size, fits in first aid kits. The pressure provides an optimal ratio of the amount of blood to the reagent, precisely calculated at the production stage.
