Medicine chamber spacer

Intended purpose

A device in the form of a small container that is placed between a nebulizer or a metered dose inhaler (MDI) and the patient's mouth, to function as a reservoir into which an aerosol medication is dispensed in order to minimize delivery of large aerosolized particles. It is typically made of plastic materials and is in the form as a small tube-like container. By holding the drug(s) after aerosolization, this device reduces the direct delivery of large aerosolized particles which would otherwise deposit in the mouth and which are intended for the lower airways. This is a reusable device.
