Abstract
An incentive spirometer is provided that allows a user to achieve Sustained Maximal Inspiration (SMI) through the use of helical tubes. Specifically, the incentive spirometer includes three chambers, wherein each chamber includes a ball traveling upwards through three helical tubes in sequential order and subsequently dropping down through a basket. Here, each of the helical tubes and corresponding baskets generally represent various levels of lung capacity achieved with repetitive use and operation of the incentive spirometer.
Claims18
A spirometer comprising:
- an air tube;
- a chamber comprised of a column, wherein the chamber further comprises a basket;
- a first helical tube, wherein the first helical tube is in fluid communication with the air tube and the chamber;
- and
- an object disposed within the first helical tube, wherein the spirometer is configured to allow the object to move through the first helical tube and through the chamber in response to inhalation;
- and
- a second helical tube and a second chamber, wherein the second chamber is in fluid communication with the air tube and the second helical tube.

A spirometer comprising:
- an air tube;
- a chamber having a basket;
- a first helical tube, wherein the first helical tube is in fluid communication with the air tube and the chamber;
- a reciprocating gate adjacent to an outlet of the first helical tube;
- and
- an object disposed within the first helical tube, wherein the spirometer is configured to allow the object to move through the first helical tube in response to inhalation;

5 more elements
A spirometer comprising:
- an air tube;
- a chamber comprised of an upright column having a top region and a lower region, wherein the chamber further comprises one or more basketball hoops;
- a helical tube having a first end and a second end, wherein the helical tube is in fluid communication with the air tube and the chamber, and wherein the first end of the helical tube is connected to the top region of the chamber and the second end of the helical tube is directly connected to the lower region of the chamber;
- and
- an object disposed within the helical tube, wherein the spirometer is configured to allow the object to move through the helical tube in response to inhalation.
