Abstract
An adapter for use in a breathing circuit including a housing with a conduit having a ventilator port adapted to be coupled to a breathing circuit and a patient port adapted to communicate with a patient interface. A medicament container receptacle communicates with the conduit between the ventilator port and the patient port. The receptacle includes a support block having a well shaped to receive a valve stem extending from a container of medicament and an actuator finger extending upwardly in the receptacle adjacent the support block. The actuator finger is adapted to actuate a dose counter coupled to the container.
