  • Patent number: 6076522
    Abstract: An apparatus (100) adapted for applying to a carrier (C) a suspension (S) comprising a suspending agent and a powdered medicament. The apparatus (110) includes a reservoir (110), a junction container (120) adapted to contain a liquid, an outlet line (130) extending from the reservoir (110) and through the junction container (120) to a pump (P), a nozzle (160) connected to the pump (P) and a sonicator (150) operatively connected to the junction container (120). The reservoir (110) is adapted to maintain the agent and the medicament admixed in suspension. The nozzle (160) is formed from an inner cylinder (161) disposed within an outer cylinder (162), thereby defining a space (X) therebetween, and includes a purge line (165) fluidly connected with the outer cylinder (162) for providing a gas jet to the space (X).
