DRUG DELIVERY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an improved drug delivery apparatus by using prescription of drugs.

SOLUTION: A drug delivery apparatus includes: a drug delivery device for selectively delivering drug-laden air or air not laden with the drug; a sensor 4 for monitoring the breathing pattern of a patient; a controller 24 arranged to control the drug delivery device to begin to deliver drug-laden air in pulses which begin when the patient is monitored by the sensor 4 to begin inhalation, the pulses having a duration which is adjusted by the controller 24 on the basis of the monitored breathing pattern of the patient; a feedback indicator 16 which indicates to a patient whether the monitored breathing pattern is effective for inhaling drug-laden air or not; a dose calculator 25 which calculates the dose delivered to the patient; and an indicator 17 which indicates to the patient when a desired dose has been delivered.
