NEBULIZING DRUG DELIVERY DEVICE FOR VENTILATOR

摘要

The present invention provides a drug delivery device (10) having a housing (12) that includes a ventilator interface module (14) and a base module (16) removeably coupled to the ventilator interface module (14). An aerosol generator (66) is disposed in the base module (16) to nebulize a drug solution (62) provided in the housing (12). The ventilator interface module (62) has an outlet port (34) through which nebulized particles of the drug solution (62) can be communicated to a user, and an inlet port (30) through which the housing (12) receives intake gas. The housing (12) has a flow path defined therein that directs intake gas from the inlet port (30) to the outlet port (34) such that the nebulized drug solution particles formed in the housing (12) are motivated toward the outlet port (34) when the base module (16) is coupled to the ventilator interface module (14). A seal arrangement (444) substantially seals the inlet port (30) and outlet port (34) from ambient atmosphere when the base module (16) is uncoupled from the ventilator interface module (14), such that intake gas can be communicated from the inlet port (30) to the outlet port (34).
