Inhaler nozzle maintenance apparatus and method
A medication dispenser includes a thermal drop generator ejector head. Medication is maintained in a pressurized container connected to a valve under the control of control electronics and to a compliant chamber. Fluid flows from the container to the chamber and to the ejector head. In a first mode the dispenser is operable to dispense aerosolized medication. In a second mode the ejector head is purged with fluid from the container to maintain the ejector head.
