Abstract
An inhalation device which induces respiratory exercise and which is inexpensive, safe and easy to handle and operate. The device includes a flow measurement container in which is housed a flow rate indicator, such as a light-weight article or ball, that normally rests at the bottom of the container. Extending through the top wall are opposed ports. A restricted port connects the chamber to atmosphere and a large opposing port to a passageway through which a person inhales. With the inhalation device of the invention, the user, nurse, or therapist can readily measure the amount inspired. A predetermined amount of inhalation for a given time is required to raise the indicator to the top of the container and predetermined additional amounts of inhalation for a given additional times are required to maintain the article at the top thereof.
