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 having a chamber in which is housed a flow rate indicator, such as a light-weight article or ball that normally rests at the bottom of the chamber. Extending into the container are opposing openings, one of which connects the chamber to a passageway through which a person inhales to remove air from the chamber, and the other of which connects the chamber to atmosphere for lifting the indicator upon inhalation.
In one embodiment the opposed openings extend through the top wall of the container. A restricted opening or port connects the chamber to atmosphere and a larger opposing opening or port to the passageway.
In another embodiment the openings are provided in the upper and lower portions of the container. The upper opening connects the top portion of the chamber to the passageway and the lower opening connects the lower portion of the chamber to atmosphere for lifting the indicator.
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 (precalibrated rate of flow) is required to raise the indicator to the top of the chamber, and predetermined additional amounts of inhalation for given additional times are required to maintain the indicator at the top thereof.
