DEVICE FOR KEEPING MEDICINAL, MAINLY ANTISEPTIC PREPARATIONS Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: device has casing with an opening, internal cavity being filled with porous capillary material impregnated with liquid medicinal preparation. Capillary rod is linearly movably and fixedly mounted in the opening due to friction-cohesion interaction with the casing. The capillary rod is engageable with the porous material inside the casing at one end, the other end protruding outside. The rod has multilayer structure, the layer being arranged in perpendicular to the longitudinal axis of the pencil, the rupture strength being less on the layer interface boundary, than that of the rod material itself. EFFECT: small-sized structure, useable under imponderability conditions. 1 dwg
