Abstract RU 2095092 C1

FIELD: medical engineering. SUBSTANCE: device has cylindrical container with piston arranged in it. Piston moves between upper and lower positions. It can be delayed in upper position by means of sectional locking facility. It is moved to lower position by spring. When locking facility is released, and piston moves to lower position under the action of spring active powder-like or liquid substance is sucked into container in dispersed state from traditional inhaler communicating with container.
