Dissolution system

Abstract

The invention provides a device for mixing a pharmaceutical from a solid supply into a parenterally acceptable liquid flowing through a set for parenteral administration of the liquid to a patient, said device comprising a first compartment defining a mixing space through which the liquid flows in a define flow direction and in which the liquid mixes with the pharmaceutical in liquid solution. The device is characterized in said mixing space being limited in an upper part thereof by a generally horizontal partition parallel to the flow direction in the mixing space and a second compartment extending generally vertically above said partition and being in liquid communication with the mixing space via perforations in said partition, said second compartment being closed and gas impervious in its upper end and defining a space for dissolution of the pharmaceutical in liquid penetrating through the perforations, and said second compartment further comprising a storage space where undissolved solid pharmaceutical is held surrounded by entrapped gas.
