A tent of a pneumoframe type (not shown in the drawing) is placed on the roof rack of a mobile station, the technological equipment of which is installed in the luggage compartment.

Automatic blood analyzer 10 is a laboratory device for detecting the presence of diseases in patients with donated blood. During testing, a system of color reagents is used, which are mixed with the patient’s blood. In automatic mode, the analyzer performs preliminary dilution, dispersion, mixing, incubation, washing, measurement and calculation of results. This device works with any samples and reagents.

In the biochemical studies mode, groups of 4 wells are simultaneously monitored, a parallel study of several kinetic tests is provided. In the immunoassay mode, a strip for 8 samples is simultaneously involved.

The use of such an analyzer makes it possible to determine infectious diseases: hepatitis A, hepatitis B, hepatitis C, chlamydia, trichomoniasis, toxoplasmosis, HIV 1, 2, measles virus, syphilis, rubella virus, polio, diphtheria, tetanus and other infectious diseases.

The test kit is a set of test strips in sealed packaging. The presence of the main communicable diseases is determined by test strips: HIV, hepatitis B, hepatitis C and syphilis. When determining the aforementioned diseases, an immunochromatographic method for detecting a substance, which is considered the most accurate, is used. Each test strip contains a membrane strip coated with antigens of infectious diseases.

When determining a particular infectious disease, a patient takes blood from a finger and puts it on a test strip, during testing, the blood interacts with antigens. If the blood sample contains antibodies to HIV 1, 2, a purple bar appears in the test area of the strip, indicating a positive test result. The absence of a color bar in the test zone indicates that the sample does not contain anti-HIV, that is, when determining one or another infectious disease, the manifestation of a color line in the control zone of the test serves as a procedural control.

The pneumoframe tent is used as an additional point for blood sampling with a large number of donors, and is installed next to the bus in the open air.

The dimensions of the tent are within: length - 8.74 m, width - 4.76 m and height - 2.75 m.

Power supply to the cabin from a stationary source of alternating single-phase / three-phase current voltage of 220 V / 380 V or from a generator with a power of 2.5-5 kW.

A battery system with an inventory of 12 or 24/220 V is used as a backup source. The vehicle’s onboard network is used as an emergency source.

The proposed mobile point of collection, storage and processing of blood works as follows.

Upon arrival of the mobile donor point to the destination, the medical team performs the following operations. Equipment for cooling polymer containers with donated blood is connected to the power supply network. Then they get packing with empty polymer containers, packaging with sterilization and consumables, the necessary medical devices and organize the flow of donors. In the donor preparation unit 1, the donor is registered and a blood test is taken to determine the blood group, Rh factor and hemoglobin level in the blood. The results of this study are entered into the medical documentation, and the donor goes to the transfusiologist.

Next, the analysis taken is sent to technological unit 3, where a blood test is performed for the presence of infectious diseases, such as HIV, hepatitis B, hepatitis C and syphilis. These studies are carried out using an automatic blood analyzer 10 or using tests 12 to detect infectious diseases. After the analysis, the patient is sent to the operating unit, seated in donor chairs and blood is taken (donation), which enters the polymer containers.

The polymer container is sent to the processing unit for accumulation in thermostat 18, after collecting the required amount in the special cassette, put the cassette in the expo-cooler 17 for cooling to the desired long-term storage temperature, and then at this temperature they put it in the refrigerator-thermostat 16, which ensures this temperature for a long time.

The second blood stream enters the refrigerator centrifuge 13, where it is divided into plasma and red blood cell mass. The erythrocyte mass enters the refrigerator 16, and the plasma into the quick-freezer 14, and then into the freezer 15.

With a large number of donors, the tent is removed from the roof rack; the equipment of the pneumatic frame module is taken out of the cargo compartment 21. They deploy a pneumatic frame module and its systems, install donor chairs, chairs for medical staff and the necessary medical equipment and devices. Then, blood is sampled from donors who have been examined in the donor training unit located in the mobile blood sampling station. The collected blood is transferred to the technological compartment of the bus for storage.

The proposed mobile blood collection and processing center provides not only the collection, storage and transportation of blood (such complexes are known), but also its processing, as well as laboratory blood tests due to the availability of modern medical equipment, creating comfortable and sanitary conditions for medical personnel and donors.

Using an automatic blood analyzer and test kits allows you to quickly-high productivity and qualitatively, without reducing accuracy, to determine the deviations in the blood of donors after the initial analyzes, determined in the donor preparation unit.

As a result of which, if a donor is found to have a contagious disease, he is suspended from donation (blood collection).

Supply of a mobile point with a tent of pneumoframe type allows serving an increased number of donors. The overall dimensions and internal equipment of the tent allow for high-quality blood sampling in any environmental conditions.

The availability of communication facilities allows monitoring the mobile station, and consulting with the central blood sampling station in case of contentious situations when determining blood tests.
