Background

What is a Metered
Dose Inhaler?

pocket-sized handheld
inhaler
 delivers standardized
dose of medication for
bronchodilation

Who Uses Them?

Patients with asthma or
chronic obstructive
pulmonary disease
(COPD)
Background

Setting?



Critical patients in hospitals
Prescriptions for outpatient
or in-home use
How to Use?





Shake Inhaler
Hold up to mouth
Press down on the inhaler to
release the medicine as you
start to breathe in slowly
Hold breath for 10 seconds
Repeat if necessary
Problem Definition

Automatic Metered Dose Inhalant (MDI)
delivery device:
 Electromechanical,
in-hospital inhalant drug
delivery system
 Patients are mechanically ventilated and
sedated
 Medication delivered automatically as
prescribed electronically
 Medication must be well shaken
(homogenized with propellant)
Design Factors

Integration with
existing
endotracheal
tubing
 Homogenization
