FIELD: medicine.SUBSTANCE: group of inventions relates to field of medicine and can be used for separate storage of medications. Flexible multi-chambered packet (10) for storing medications contains three chambers, located near each other, with first chamber (1) partially dividing upper chamber (2) from third lower chamber (3) by welded seams (4) and (5), and second chamber (2) and third chamber (3) being partially connected by welded seam (6). Welded seams (5) and (6) are made with possibility of detachment when pressure is produced on packet (10), with welded seams (5) and (6) together forming shape of upturned letter "V" with increasing angle between lines of letter "V" towards basis point (8), in which welded seams (5) and (6) start. Welded seam (4) is made non-detachable when pressure is produced on packet (10) and starts in basis point (8) of letter "V". Seams (4), (5) and (6) end in fact at right angle to circular welded seam (7) of packet (10). Basis point (8) of letter "V" is fixed and does not detach when pressure is produced on packet (10). Packet (10) also contains valve for hanging and medical port (9). Group of inventions also relates to application of said packet for sterilisation, spatially separate storage, fast mixing and introduction of carbohydrates, fats and amino acids.EFFECT: group of inventions provides complete emptying of multi-chambered packet.5 cl, 1 dwgГруппа изобретений относится к области медицины и может быть использована для раздельного хранения медицинских препаратов. Гибкий многокамерный пакет (10) для хранения медицинских препаратов содержит три расположенные рядом камеры, причем первая камера (1) частично разделяет вторую верхнюю камеру (2) от третьей нижней камеры (3) сварными швами (4) и (5), а вторая камера (2) и третья камера (3) частично соединены сварным швом (6). Сварные швы (5) и (6) выполнены с возможностью отслаивания при оказании давления на пакет (10), при этом сварные швы (5) и (6) вместе образуют форму перевернутой
