Abstract
Abstract A device and method for increasing inhalation strength and capacity of the lungs. The device includes an air inlet and air outlet which are interconnected by a conduit. A valve in the conduit is opened by the pressure differential created when the user inhales through a mouthpiece. The valve is biased to a normally closed position. The biasing force is adjustable so that the force required to open the valve during inhalation can be varied to increase the strength of the users' lungs. A timer is provided for monitoring the length of time of successive inhalations. The method includes the steps of inhaling through a mouthpiece and flexible conduit, creating a vacuum in said conduit of sufficient force to open a variable resistance valve, and breathing in atmospheric air to fill the lungs. The amount of air inhaled is monitored.

Claim 4
Dependent Claim
19 words
A device as defined in claim 1 including means for measuring the vacuum drawn by the user during inhalation.
Claim 5
Dependent Claim
22 words
A device as defined in claim 3 wherein said vacuum measuring means is disposed between said first valve and said air outlet.
Claim 6
Dependent Claim
21 words

Claim 7
Dependent Claim
51 words
A device as defined in claim 5 wherein said measuring means includes pressure differential detecting means disposed between said inlet and said first valve, a timer and a switch means, said switch means being operable to complete a circuit to said timer when the presence of a pressure differential is detected.
Claim 8
Dependent Claim
44 words
A device as defined in claim 5 including means for selecting a predetermined interval during which said first valve is to be maintained open, an energizable signal, and means for energizing said signal when said first valve has been opened for said predetermined interval.

A device as defined in claim 1 including bellows, said bellows having an outlet, said bellows outlet being connected to said air inlet, a venting valve in said conduit between said bellows and said first valve, said venting valve being normally closed, and energizable means for selectively opening said venting valve to permit air to enter said conduit and vent said device.
Claim 10
Dependent Claim
43 words
A device as defined in claim 8, including a presettable timer which can be set to a predetermined interval, said energizable means being electrically coupled to said timer so that after said predetermined interval said energizable means is energized to vent said device.
Claim 11
Dependent Claim
25 words
A device as defined in claim 8 including means for selecting the time interval during which said venting valve is open to vent said device.
Claim 12
Dependent Claim
18 words
A device as defined in claim 10 wherein said means interval for selecting the time includes a timer.
Claim 13
Dependent Claim
26 words
A device as defined in claim 8 including means for selecting the time interval between the cessation of inhalation and the opening of said venting valve.
Claim 14
Dependent Claim
18 words
