FIELD: medical engineering. SUBSTANCE: microoperational chamber has base with projections and recesses. Changeable one-time block is positioned on projections. It is made of optically transparent plastic. Block consists of upper and lower plates interconnected by posts. Spring clamps positioned on permanent magnets secured in base hold it. Sterile silicone oil and cells with physiological solution are introduced into cavity located between plates. After operations are completed, clamps are turned; used-up changeable block is removed and replaced by new one. EFFECT: easy assembly and removal of block. 3 cl, 2 dwg
