An incentive inhalation device which induces respiratory exercise and which is inexpensive, safe and easy to handle and operate. The device includes a container having a plurality of flow measurement chambers which are vertical when the device is in its upright position. In each chamber is housed a flow rate indicator, such as a light-weight article and ball, that normally rests at the bottom thereof. The bottom of each chamber is open to surrounding atmosphere and the top of each chamber is open to a passageway. In operation, the patient or user withdraws air from the air passageway and chambers. When the patient achieves the precalibrated flow rate or rates, the indicators will sequentially rise to the top of each chamber. In one embodiment of the invention the emphasis of the device is on duration by making the precalibrated rate of flow essentially the same for each chamber. In another embodiment of the invention the emphasis of the device is on increased effort and duration by having different precalibrated rates of flow for at least two of the chambers. To prevent disruption of air flow into the passageway and surprise or shock to the user, means are provided in the last chamber of the device to prevent the indicator from closing that chamber to the air passageway.

Inhalation device

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.

In each chamber is housed a flow rate indicator, such as a light-weight article and ball, that normally rests at the bottom thereof. The bottom of each chamber is open to surrounding atmosphere and the top of each chamber is open to a common passageway. In operation, the patient or user withdraws air from the common air passageway and chambers. When the patient achieves a precalibrated flow rate the indicators sequentially rise to the top of each chamber. To prevent disruption of air flow into the passageway and surprise or shock to the user, means are provided in the last chamber to prevent the indicator from closing the last chamber to the common air passageway.
