ABSTRACT:
A therapeutic device for exercising and stimulating the lung with the aid of a mouthpiece (1) which sealingly co-acts with the lips of the user during the exhalation phase of a breathing cycle. The mouthpiece is connected to a cylindrical, hollow extension (2) and communicates with the surrounding atmosphere through an opening (3) of adjustable area disposed in the extension. The opening (3) is located in the circumference of the extension (2) and the extension is closed-off with the aid of a sealing plug having the function of a valve (4). The valve is rotatable and has a surface which co-acts with the inner surface of the extension, such that the exposed area of the opening (3) can be adjusted by rotation of the valve. To facilitate adjustment of the exposed area of the opening, the valve (4) and the extension (2) are provided with respective, mutually co-acting promontories and recesses which are effective in releasably fixing the valve in relation to the extension in a desired rotational position selected from a number of relative rotational positions, by rotation of the valve relative to the extension. This enables the device to be readily adjusted to a pre-determined exhalation resistance.
