(54) APPARATUS FOR STORAGE OF THE COMPONENTS OF THE BLOOD

: , .one

This is related to medical technology, and to devices for storing blood combs, used in hematology and transfusion.

When storing the concentrates, the method of their cryopreservation is used. For short-term storage of platelets or leukocytes without significant reduction in their functional properties (not more than 72 hours), storage in plastic containers at a temperature of -44 ° C or +22 ° C with constant shaking is used.

And the device for storing blood components, including a vibrator made in the form of a movable plate connected to a source of vibrations, and a plastic container for a platelet concentrate or leukocyte, mounted on a support (11.

 the device has a disadvantage, since the vibrator gives the reciprocating movement of the entire plastic container only in the vertical direction up-down).

Monotonous linear movement does not contribute to good mixing of the KROE cells, which is what leads to the storage process of the aggregates. In addition, when the plastic container is supported on the support in the vertical direction, the latter becomes stable and needs to be fixed.

The purpose of the invention is to improve the preservation of the functional properties of blood cells.

FIG. 1 is a schematic diagram of the device; in fig. 2 - the scheme of his work. 393 The device consists of a plastic container 1 for a concentrate of blood cells located on the base 2 of the vibrator, the movable plate 3 is tightly pressed against the container 1. The base 2 of the vibrator is electrically isolated from the movable plate 3 ,; which is connected to the positive pole 4 of the electrical outbreak of 5 electric charges and with the exciter 6 of its oscillations. The base 2, located in parallel and horizontally movable plate 3, is connected to the negative pole 7 of the source / electric charge 5. The device is located in the thermostat 8. The device operates as follows. The plastic container 1 is placed on the base 2, then the movable plate 3 is brought and lightly pressed to the container 1 so that the container is sloped up to Aj 2030 mm, and the container content in the vertex section 9 is raised to Aj 30-40 mm. Include a source of 5 electric, charges and a pathogen of 6 oscillations, as well as a thermostat 8.. Pathogen 6 causes plate 3 to reciprocate B 2-5 mm. At the same time, container 1 then decreases, then expands, a part of its contents flows over segment 9, the level of A2 constantly changes. Blood corpuscles in total are acted upon by vertical B and horizontal G flows, which effectively mix these elements. Bearing in mind that all blood cells normally carry on their Membrane, as a rule, a negative charge, using the repulsive effect of dissimilar charges, one can more and more prevent aggregation. An additional factor is plate charge. The base 2 with its field tends to throw up blood cells upward, and the movable plate 3 - even more fully, You can. so choose the magnitude of the charge of the base 2 and the plates 3 so that the lifting electrophoretic force D completely compensates for the force of gravity E of the blood cells, and they would receive zero buoyancy. In this case, the process would be optimal. The thermostat allows the storage temperature to be maintained. The proposed device has significant advantages. If, in a known device, on the cells of the crooks, besides the forces of gravity C, only the vertical forces B of vibration act, then the proposed device additionally has horizontal forces G, vertical lifting electrophoretic forces D of base 2 and plate 3. All this will more effectively prevent the aggregation of blood cells and it is better to preserve their functional properties. Compressing plastic containers requires much less effort than vibrating them. This reduces the power, size and cost of the device. Due to the fact that the container lies with its entire mass on the base, its stability is preserved and no additional fixing devices are required. Claim 1. Device for storing blood components, including a plastic container, a vibrator containing a movable plate connected to a source of vibrations, so that, in order to improve the preservation of the functional properties of blood cells, the vibrator contains a base, a movable plate located above the base, the plastic container is mounted on the latter, while the device contains a source of electrical charges associated with the base and the plate with opposite poles. 2.
