DEVICE FOR EXTRACTION, STORAGE AND/OR PROCESSING OF BLOOD OR OTHER SUBSTANCES OF HUMAN OR ANIMAL ORIGIN AND FOR USE OF BLOOD COMPOUNDS OR OTHER BIOLOGICAL COMPOUNDS
FIELD: medicine.SUBSTANCE: device for extraction, storage and/or treatment of blood or other substances of human or animal origin, as well as for the use of blood or other biological compounds, contains a housing with an inner piston moving longitudinally. The housing has the first end in which a channel is formed that connects the interior space of the housing between the piston and the channel with a space outside the housing and the second end through which the piston projects outwardly and which is hermetically sealed from the interior by means of a piston. At least a portion of the piston can be detached from the rest of the device, so that the piston does not protrude from the housing. The piston comprises at least one locking surface. The housing comprises at least one locking surface adapted to come into contact with the piston locking surface and to provide one-way locking of the piston which results in resistance to piston movement towards the first end, while the piston can move freely back towards the second end. The device further comprises a sealing member to seal the channel of the first end of the housing if a needle is introduced into the channel, so that a vacuum may exist in the interior space.EFFECT: invention is universal； can be used for various purposes, reduces the number of transfers between containers that are normally required in procedures includong extraction, processing and storage of blood or blood compounds； reduces or eliminates the negative effects caused by the loss of vacuum over time in devices for blood extraction and storage.20 cl, 24 dwgИзобретение относится к медицинской технике, а именно к устройству для извлечения, хранения и/или обработки крови либо других веществ человеческого или животного происхождения, а также для использования соединений крови или других биологических соединений.
