FIELD: dispensing of liquids; medicine.
SUBSTANCE: invention relates to devices for drop dispensing of liquids. Proposed device contains reservoir with wall flexibly deformable at hand pressing and terminating in rigid neck I which metering head is installed diaphragm featuring hydrophilic and hydrophobic properties and, in preferable version, antimicrobic properties, is arranged in metering head square to direction of liquid flow to channel designed for forcing liquid out. Said diaphragm lest in air into reservoir after part of liquid has passed out at stage of forcing out, and vial restores its initial shape after each dispensing operation. Breakable partition is provided which isolates diaphragm from liquid in vial prior to first forcing out when it is ruptured by special punch rigidly coupled with metering head.
EFFECT: improved reliability at storing and use, provision of means to protect diaphragm from damage.
